Problems to be solved by the invention
However, in a state before the pair of fixing portions are fixed to the vertical column, a gap is formed between each of the pair of fixing portions and the vertical column in order to facilitate insertion of the vertical column between the pair of fixing portions. When the pair of fixing portions are fixed to the vertical column, the vertical column is easily deformed by the slit, so that the gap between each of the pair of fixing portions and the vertical column is eliminated. Since the notch is formed in the center of the vertical column in the depth direction of the car room, there is a problem that: in order to eliminate the gap between each of the pair of fixing portions and the vertical column when the vertical column is deformed in a state in which the vertical column extends in the vertical direction, trial and error of the fastening amount of each of the plurality of bolts and the fastening order of each of the plurality of bolts must be repeated, and the assembly work efficiency is low.
The present invention has been made to solve the above-described problems, and an object thereof is to provide an elevator car frame device capable of improving the assembly work efficiency.
Means for solving the problems
The elevator car frame device of the invention comprises: a lower beam; an upper beam disposed above the lower beam; and a vertical column that is bridged between the lower beam and the upper beam, at least one of the lower beam and the upper beam having a pair of fixing portions facing each other, the vertical column having an insertion portion that is inserted between the pair of fixing portions, the insertion portion including: a first column mounting part fixed to one of the pair of fixing parts by a fastener; and a second column mounting part fixed to the other of the pair of fixing parts by a fastener, wherein the rigidity of the first column mounting part and the rigidity of the second column mounting part are different from each other.
Effects of the invention
According to the elevator car frame device of the present invention, since the rigidity of the first pillar mounting portion and the rigidity of the second pillar mounting portion are different from each other, when the pair of fixing portions are fixed to the vertical pillars by the fasteners, the higher rigidity of the first pillar mounting portion and the second pillar mounting portion is smaller than the lower rigidity. Therefore, by fixing the fixing portion to the first column attachment portion or the second column attachment portion with higher rigidity, the vertical column can be deformed such that the gap between each of the pair of fixing portions and the vertical column disappears in the state where the vertical column extends in the vertical direction. Thus, trial and error of the fastening amounts of the plurality of fasteners and the fastening order of the plurality of fasteners do not have to be repeated. As a result, the efficiency of the assembly work of the elevator car frame device can be improved.

Detailed Description
Implementation mode one
Fig. 1 is a front view showing an elevator car frame device according to a first embodiment of the present invention, fig. 2 is a side view showing the elevator car frame device of fig. 1, and fig. 3 is a cross-sectional view taken along the line III-III of fig. 1 in the direction of an arrow. An elevator car frame device according to a first embodiment of the present invention supports a car room, not shown. The elevator car frame device is provided with: a lower beam 1 that is provided so as to extend in the width direction of the car room and supports the car room; an upper beam 2 disposed above the lower beam 1; and a pair of vertical columns 3 which are erected between the lower beam 1 and the upper beam 2. The pair of vertical columns 3 are arranged to extend upward from the lower beam 1. The upper beam 2 is disposed above the car room so as to be bridged over the upper end portions of the pair of vertical pillars 3. The pair of vertical pillars 3 is arranged such that the car room is sandwiched between the pair of vertical pillars 3 in the width direction. The width direction of the car room is a lateral width direction of the car room, and is a direction of an arrow a in fig. 1.
The underbeam 1 has a pair of fixing portions 11 that sandwich the lower end portions of the vertical columns 3 in the depth direction of the car room. The pair of fixing portions 11 face each other in the depth direction of the car room. The facing direction, which is the facing direction of the pair of fixing portions 11, is the depth direction of the car room. The depth direction of the car room is the direction of arrow B in fig. 2. The pair of fixing portions 11 are fixed to the vertical column 3 by a plurality of fasteners 12. Examples of the fastener 12 include a bolt and a screw.
The upper beam 2 has a pair of fixing portions 21 that sandwich the upper end portions of the vertical columns 3 in the depth direction B of the car room. The pair of fixing portions 21 face each other in the depth direction of the car room. The facing direction, which is the facing direction of the pair of fixing portions 21, is the depth direction B of the car room. The pair of fixing portions 21 are fixed to the vertical column 3 by a plurality of fasteners 22. Examples of the fastener 22 include a bolt and a screw.
The vertical column 3 has: a first vertical column member 31 that spans between the lower beam 1 and the upper beam 2; a second vertical column member 32 that spans between the lower beam 1 and the upper beam 2; and a plurality of coupling members 33 that couple the first vertical column member 31 and the second vertical column member 32. The first vertical pillar member 31 is disposed closer to the landing side than the second vertical pillar member 32 in the depth direction B of the car room. In other words, the second vertical pillar member 32 is disposed farther from the landing in the depth direction B of the car room than the first vertical pillar member 31. The plurality of coupling members 33 are arranged at intervals in the height direction.
The dimension of the first vertical column member 31 in the depth direction B of the car room is the same throughout the entire height direction. The dimension of the second vertical column member 32 in the depth direction B of the car room is the same throughout the entire height direction.
The vertical column 3 has an insertion portion 34 inserted between the pair of fixing portions 11. The insertion portion 34 includes: a first post mounting portion 311 fixed to one of the pair of fixing portions 11 by a fastener 12; and a second column mounting portion 321 fixed to the other of the pair of fixing portions 11 by a fastener 12. The vertical column 3 has an insertion portion 35 inserted between the pair of fixing portions 21. The insertion portion 34 includes: a first column mounting portion 312 fixed to one of the pair of fixing portions 21 by a fastener 22; and a second column mounting part 322 fixed to the other of the pair of fixing parts 11 by a fastener 22. The first vertical column member 31 includes a first column mounting portion 311 and a first column mounting portion 312. The second vertical column member 32 includes a second column mounting portion 321 and a second column mounting portion 322. The first vertical column member 31 and the second vertical column member 32 are separate members from each other.
The first vertical pillar member 31 and the second vertical pillar member 32 are different in size from each other in the depth direction B of the car room. Therefore, the first vertical column member 31 and the second vertical column member 32 have different rigidities from each other. Thus, the first column mounting part 311 and the second column mounting part 321 have different rigidities from each other, and the first column mounting part 312 and the second column mounting part 322 have different rigidities from each other.
Specifically, the first vertical pillar member 31 is larger in size than the second vertical pillar member 32 in the depth direction B of the car room. Therefore, the rigidity of the first vertical column member 31 is higher than the rigidity of the second vertical column member 32. Thus, the rigidity of the first column mounting portion 311 is higher than that of the second column mounting portion 321, and the rigidity of the first column mounting portion 312 is higher than that of the second column mounting portion 322. The rigidity ratio of the first pillar mounting portion 311 to the second pillar mounting portion 321 in the depth direction B of the car room is, for example, approximately 5:1 to 10: 1. The rigidity ratio of the first column mounting portion 312 to the second column mounting portion 322 in the depth direction B of the car room is, for example, approximately 5:1 to 10: 1.
Preferably, the dimension of the connecting member 33 arranged from the lower end of the vertical column 3 to the lowermost portion of the plurality of connecting members 33 is larger than the dimension of the fixing portion 11 in the height direction. In other words, it is preferable that the coupling member 33 is not disposed between the pair of fixing portions 11. Further, it is preferable that the dimension of the coupling member 33 disposed uppermost among the plurality of coupling members 33 from the upper end portion of the vertical column 3 is larger than the dimension of the fixing portion 21 in the height direction. In other words, it is preferable that the coupling member 33 is not disposed between the pair of fixing portions 21.
Further, spacers may be inserted into the gap between the vertical column 3 and the pair of fixing portions 11 and the gap between the vertical column 3 and the pair of fixing portions 21. In this case, in order to avoid deformation of the spacer when the vertical column 3 is inserted between the pair of fixing portions 11 or when the vertical column 3 is inserted between the pair of fixing portions 21, the dimension of the spacer in the thickness direction needs to be 0.5mm or more. Therefore, even when the spacer is used, a total space of less than 0.5mm is formed between the vertical column 3 and the spacer and between the spacer and the fixing portion 11, and a total space of less than 0.5mm is formed between the vertical column 3 and the spacer and between the spacer and the fixing portion 21.
Since the dimension of the vertical column 3 in the height direction is 10 times or more the dimension of the fixing portion 11 and the fixing portion 21 in the height direction, the amount of deformation of the vertical column 3 is 0.5(mm) × 10 — 5(mm) by simple calculation. The amount of deformation of the vertical column 3 of ± 5mm has been reduced by trial and error of the amount and order of fastening the fastener 12 and the fastener 22. In the present invention, since the rigidity ratio of the first column mounting part 311 to the second column mounting part 321 is, for example, between 5:1 and 10:1, and the rigidity ratio of the first column mounting part 312 to the second column mounting part 322 is, for example, between 5:1 and 10:1, the deformation amount of the vertical column 3 of ± 5mm can be suppressed to between ± 0.5mm and ± 1mm by assembling well in order. The deformation amount of the vertical column 3 of this degree can be sufficiently absorbed by a guide shoe or the like that guides the elevator car frame device. Therefore, it is not necessary to correct the deformation of the vertical column 3. Therefore, the elevator car frame device with high precision and high working efficiency can be obtained.
Next, the procedure of assembling the elevator car frame device will be described. First, the lower end of the vertical column 3 is inserted between the pair of fixing portions 11, and the upper end of the vertical column 3 is inserted between the pair of fixing portions 21. In order to easily fit the vertical column 3 between the pair of fixing portions 11, a gap is formed between each of the pair of fixing portions 11 and the vertical column 3. Further, in order to easily fit the vertical column 3 between the pair of fixing portions 21, a gap is formed between each of the pair of fixing portions 21 and the vertical column 3.
Then, the fixing portion 11 is fixed to the first post mounting portion 311 with a plurality of fasteners 12, and the fixing portion 21 is fixed to the first post mounting portion 312 with a plurality of fasteners 22. When the fixing portion 11 is fixed to the first pillar attachment portion 311 and the fixing portion 21 is fixed to the first pillar attachment portion 312, the gap between the first pillar attachment portion 311 and the fixing portion 11 in the depth direction B of the car room is eliminated, and the gap between the first pillar attachment portion 312 and the fixing portion 21 in the depth direction B of the car room is eliminated. Accordingly, the gap between the second column attachment portion 321 and the fixing portion 11 in the depth direction B of the car room is increased, and the gap between the second column attachment portion 322 and the fixing portion 21 in the depth direction B of the car room is increased.
Then, the fixing part 11 is fixed to the second column mounting part 321 with a plurality of fasteners 12, and the fixing part 21 is fixed to the second column mounting part 322 with a plurality of fasteners 22. At this time, the vertical column 3 deforms so that the gap between the second column mounting part 321 and the fixing part 11 and the gap between the second column mounting part 322 and the fixing part 21 disappear. Further, at this time, since the rigidity of the first column mounting part 311 is higher than that of the second column mounting part 321, and the rigidity of the first column mounting part 312 is higher than that of the second column mounting part 322, the amount of deformation of the first column mounting part 311 is smaller than that of the second column mounting part 321, and the amount of deformation of the first column mounting part 312 is smaller than that of the second column mounting part 322. Therefore, the vertical column 3 can be deformed so that the gap between each of the pair of fixing portions 11 and the vertical column 3 and the gap between each of the pair of fixing portions 21 and the vertical column 3 disappear in a state where the vertical column 3 extends in the vertical direction.
As described above, according to the elevator car frame device according to the first embodiment of the present invention, since the rigidity of the first pillar mounting portion 311 is higher than the rigidity of the second pillar mounting portion 321, when the pair of fixing portions 11 are fixed to the vertical pillar 3 by the fastener 12, the first pillar mounting portion 311 deforms less than the second pillar mounting portion 321. Therefore, by fixing the fixing portion 11 to the first column attachment portion 311, the vertical column 3 can be deformed such that the gap between each of the pair of fixing portions 11 and the vertical column 3 disappears in the state where the vertical column 3 extends in the vertical direction. Thus, trial and error of the fastening amounts of the fasteners 12 and the fastening order of the fasteners 12 do not have to be repeated. As a result, the efficiency of the assembly work of the elevator car frame device can be improved.
In this elevator car frame device, since the rigidity of the first pillar mounting portion 312 is higher than the rigidity of the second pillar mounting portion 322, when the pair of fixing portions 21 are fixed to the vertical pillars 3 by the fasteners 22, the first pillar mounting portion 312 deforms less than the second pillar mounting portion 322. Therefore, by fixing the fixing portion 21 to the first column attachment portion 312, the vertical column 3 can be deformed such that the gap between each of the pair of fixing portions 21 and the vertical column 3 disappears in the state where the vertical column 3 extends in the vertical direction. Thus, trial and error of the fastening amounts of the fasteners 22 and the fastening order of the fasteners 22 do not have to be repeated. As a result, the efficiency of the assembly work of the elevator car frame device can be improved.
Further, the vertical column 3 has: a first vertical column member 31 including a first column attachment portion 311; a second vertical column member 32 including a second column mounting portion 321; and a coupling member 33 that couples the first vertical column member 31 and the second vertical column member 32, the first vertical column member 31 and the second vertical column member 32 being separate members from each other. Thus, the first column mounting part 311 and the second column mounting part 321 can be formed with a simple structure. Further, the vertical column 3 has: a first vertical column member 31 including a first column attachment portion 312; a second vertical column member 32 including a second column mounting portion 322; and a coupling member 33 that couples the first vertical column member 31 and the second vertical column member 32, the first vertical column member 31 and the second vertical column member 32 being separate members from each other. Thus, the first column mounting part 312 and the second column mounting part 322 can be formed with a simple structure.
Second embodiment
Fig. 4 is a front view showing an elevator car frame device according to a second embodiment of the present invention, fig. 5 is a side view showing the elevator car frame device of fig. 4, and fig. 6 is a cross-sectional view taken along the line VI-VI in fig. 4 in the direction of an arrow. In the first embodiment, a description has been given of a configuration in which the vertical column 3 includes the first vertical column member 31, the second vertical column member 32, and the plurality of coupling members 33. The structure of the first embodiment is suitable for an elevator car frame device for a large-sized elevator or an elevator car frame device for a large-capacity elevator in which the vertical column 3 cannot be formed of one member. The structure of the second embodiment is suitable for an elevator car frame device for a medium-sized elevator or an elevator car frame device for a medium-sized elevator in which the vertical column 3 can be formed of one member.
A slit 341 is formed in the insertion portion 34 of the vertical column 3. The slit 341 is disposed so as to extend in the height direction. The slit 341 is disposed so as to be offset in the depth direction B from the center of the insertion portion 34 in the depth direction B of the car room. Specifically, the notch 341 is disposed so as to be offset from the center of the insertion portion 34 in the depth direction B of the car room in a direction away from the landing in the depth direction B. The insertion portion 34 of the vertical column 3 includes: a first post mounting portion 311 fixed to one of the pair of fixing portions 11 by a fastener 12; and a second column mounting portion 321 fixed to the other of the pair of fixing portions 11 by a fastener 12. The cutout 341 is disposed between the first pillar mounting portion 311 and the second pillar mounting portion 321 in the depth direction B of the car room. By forming the cutout 341 in the insertion portion 34 of the vertical column 3, the rigidity of the first column mounting portion 311 and the rigidity of the second column mounting portion 321 are different from each other.
A notch 351 is formed in the insertion portion 35 of the vertical column 3. The notch 351 is disposed to extend in the height direction. The notch 351 is disposed so as to be offset in the depth direction B from the center of the insertion portion 35 in the depth direction B of the car room. Specifically, the notch 351 is disposed so as to be offset from the center of the insertion portion 34 in the depth direction B of the car room in a direction away from the landing in the depth direction B. The insertion portion 35 of the vertical column 3 has: a first column mounting portion 312 fixed to one of the pair of fixing portions 21 by a fastener 22; and a second column mounting part 322 fixed to the other of the pair of fixing parts 21 by a fastener 22. The notch 351 is disposed between the first column attachment portion 312 and the second column attachment portion 322 in the depth direction B of the car room. By forming the notch 351 in the insertion portion 35 of the vertical column 3, the rigidity of the first column attachment portion 312 and the rigidity of the second column attachment portion 322 are different from each other.
Specifically, the rigidity of the first column mounting portion 311 is higher than that of the second column mounting portion 321, and the rigidity of the first column mounting portion 312 is higher than that of the second column mounting portion 322. The rigidity ratio of the first pillar mounting portion 311 to the second pillar mounting portion 321 in the depth direction B of the car room is, for example, approximately 5:1 to 10: 1. The rigidity ratio of the first column mounting portion 312 to the second column mounting portion 322 in the depth direction B of the car room is, for example, approximately 5:1 to 10: 1. The other structure is the same as in the first embodiment.
Preferably, the dimension in the longitudinal direction of the slit 341 is larger than the dimension in the height direction of the fixing portion 11, and the dimension in the longitudinal direction of the slit 351 is larger than the dimension in the height direction of the fixing portion 21. In other words, it is preferable that the slit 341 be formed over the entire height between the pair of fixing portions 11, and the slit 351 be formed over the entire height between the pair of fixing portions 21.
Next, the procedure of assembling the elevator car frame device will be described. First, the lower end of the vertical column 3 is inserted between the pair of fixing portions 11, and the upper end of the vertical column 3 is inserted between the pair of fixing portions 21. In order to easily fit the vertical column 3 between the pair of fixing portions 11, a gap is formed between each of the pair of fixing portions 11 and the vertical column 3. Further, in order to easily fit the vertical column 3 between the pair of fixing portions 21, a gap is formed between each of the pair of fixing portions 21 and the vertical column 3.
Then, the fixing portion 11 is fixed to the first post mounting portion 311 with a plurality of fasteners 12, and the fixing portion 21 is fixed to the first post mounting portion 312 with a plurality of fasteners 22. When the fixing portion 11 is fixed to the first pillar attachment portion 311 and the fixing portion 21 is fixed to the first pillar attachment portion 312, the gap between the first pillar attachment portion 311 and the fixing portion 11 in the depth direction B of the car room is eliminated, and the gap between the first pillar attachment portion 312 and the fixing portion 21 in the depth direction B of the car room is eliminated. Accordingly, the gap between the second column attachment portion 321 and the fixing portion 11 in the depth direction B of the car room is increased, and the gap between the second column attachment portion 322 and the fixing portion 21 in the depth direction B of the car room is increased.
Then, the fixing part 11 is fixed to the second column mounting part 321 with a plurality of fasteners 12, and the fixing part 21 is fixed to the second column mounting part 322 with a plurality of fasteners 22. At this time, the vertical column 3 deforms so that the gap between the second column mounting part 321 and the fixing part 11 and the gap between the second column mounting part 322 and the fixing part 21 disappear. Further, at this time, since the rigidity of the first column mounting part 311 is higher than that of the second column mounting part 321, and the rigidity of the first column mounting part 312 is higher than that of the second column mounting part 322, the amount of deformation of the first column mounting part 311 is smaller than that of the second column mounting part 321, and the amount of deformation of the first column mounting part 312 is smaller than that of the second column mounting part 322. Therefore, the vertical column 3 can be deformed so that the gap between each of the pair of fixing portions 11 and the vertical column 3 and the gap between each of the pair of fixing portions 21 and the vertical column 3 disappear in a state where the vertical column 3 extends in the vertical direction.
As described above, according to the elevator car frame device of the second embodiment of the present invention, since the cutout 341 is formed in the insertion portion 34 and the cutout 341 is disposed between the first pillar mounting portion 311 and the second pillar mounting portion 321 in the depth direction B of the car room, the first pillar mounting portion 311 and the second pillar mounting portion 321 can be formed with a simple configuration. Further, since the notch 351 is formed in the insertion portion 35 and the notch 351 is disposed between the first column attachment portion 312 and the second column attachment portion 322 in the depth direction B of the car room, the first column attachment portion 312 and the second column attachment portion 322 can be formed with a simple configuration.
Further, since the slit 341 is disposed so as to extend in the height direction and so as to be offset in the depth direction B from the center of the insertion portion 34 in the depth direction B of the car compartment, the first column mounting portion 311 and the second column mounting portion 321 can be formed with a simple configuration. Further, since the notch 351 is disposed so as to extend in the height direction and so as to be offset in the depth direction B from the center of the insertion portion 35 in the depth direction B of the car compartment, the first column attachment portion 312 and the second column attachment portion 322 can be formed with a simple configuration.
Third embodiment
Fig. 7 is a front view showing an elevator car frame device according to a third embodiment of the present invention, fig. 8 is a side view showing the elevator car frame device of fig. 7, and fig. 9 is a cross-sectional view taken along the line IX-IX of fig. 7 in the direction of an arrow. In the second embodiment, a description has been given of a configuration in which the vertical column 3 is formed of one member and the cuts 341 and 351 are formed in the vertical column 3. The structure of the second embodiment is suitable for an elevator car frame device for a medium-sized elevator or an elevator car frame device for a medium-sized elevator. The configuration of the third embodiment is suitable for an elevator car frame device for a small-sized elevator or an elevator car frame device for a small-sized elevator in which the notches 341 and 351 cannot be formed in the vertical column 3.
A groove 342 is formed in the insertion portion 34 of the vertical column 3. The groove 342 is disposed so as to extend in the height direction. The groove 342 is disposed so as to be offset in the depth direction B from the center of the insertion portion 34 in the depth direction B of the car room. Specifically, the groove 342 is disposed so as to be offset from the center of the insertion portion 34 in the depth direction B of the car room in a direction away from the landing in the depth direction B. The insertion portion 34 of the vertical column 3 includes: a first post mounting portion 311 fixed to one of the pair of fixing portions 11 by a fastener 12; and a second column mounting portion 321 fixed to the other of the pair of fixing portions 11 by a fastener 12. The groove 342 is disposed between the first column mounting portion 311 and the second column mounting portion 321 in the depth direction B of the car room.
The portion of the insertion portion 34 where the groove 342 is formed has a thickness. That is, the portion of the insertion portion 34 where the groove 342 is formed does not penetrate in the thickness direction. The dimension in the thickness direction of the portion of the insertion portion 34 where the groove 342 is formed is smaller than the dimension in the thickness direction of the portion of the insertion portion 34 where the groove 342 is not formed. By forming the groove 342 in the insertion portion 34 of the vertical column 3, the rigidity of the first column attachment portion 311 and the rigidity of the second column attachment portion 321 are different from each other.
A groove 352 is formed in the insertion portion 35 of the vertical column 3. The groove 352 is disposed to extend in the height direction. The groove 352 is disposed so as to be offset in the depth direction B from the center of the insertion portion 35 in the depth direction B of the car room. Specifically, the groove 352 is disposed so as to be offset from the center of the insertion portion 35 in the depth direction B of the car room in a direction away from the landing in the depth direction B. The insertion portion 35 of the vertical column 3 has: a first column mounting portion 312 fixed to one of the pair of fixing portions 21 by a fastener 22; and a second column mounting part 322 fixed to the other of the pair of fixing parts 11 by a fastener 22. The groove 352 is disposed between the first column mounting portion 312 and the second column mounting portion 322 in the depth direction B of the car room.
The portion of the insertion portion 35 where the groove 352 is formed has a thickness. That is, the portion of the insertion portion 35 where the groove 352 is formed does not penetrate in the thickness direction. The dimension in the thickness direction of the portion of the insertion portion 35 where the groove 352 is formed is smaller than the dimension in the thickness direction of the portion of the insertion portion 35 where the groove 352 is not formed. By forming the groove 352 in the insertion portion 35 of the vertical column 3, the rigidity of the first column attachment portion 312 and the rigidity of the second column attachment portion 322 are different from each other.
Specifically, the rigidity of the first column mounting portion 311 is higher than that of the second column mounting portion 321, and the rigidity of the first column mounting portion 312 is higher than that of the second column mounting portion 322. The rigidity ratio of the first pillar mounting portion 311 to the second pillar mounting portion 321 in the depth direction B of the car room is, for example, approximately 5:1 to 10: 1. The rigidity ratio of the first column mounting portion 312 to the second column mounting portion 322 in the depth direction B of the car room is, for example, approximately 5:1 to 10: 1. The other structure is the same as in the second embodiment.
Preferably, the dimension of the groove 342 in the longitudinal direction is larger than the dimension of the fixing portion 11 in the height direction, and the dimension of the groove 352 in the longitudinal direction is larger than the dimension of the fixing portion 21 in the height direction. In other words, it is preferable that the groove 342 is formed in the entire height direction between the pair of fixing portions 11, and the groove 352 is formed in the entire height direction between the pair of fixing portions 21.
Next, the procedure of assembling the elevator car frame device will be described. First, the lower end of the vertical column 3 is inserted between the pair of fixing portions 11, and the upper end of the vertical column 3 is inserted between the pair of fixing portions 21. In order to easily fit the vertical column 3 between the pair of fixing portions 11, a gap is formed between each of the pair of fixing portions 11 and the vertical column 3. Further, in order to easily fit the vertical column 3 between the pair of fixing portions 21, a gap is formed between each of the pair of fixing portions 21 and the vertical column 3.
Then, the fixing portion 11 is fixed to the first post mounting portion 311 with a plurality of fasteners 12, and the fixing portion 21 is fixed to the first post mounting portion 312 with a plurality of fasteners 22. When the fixing portion 11 is fixed to the first pillar attachment portion 311 and the fixing portion 21 is fixed to the first pillar attachment portion 312, the gap between the first pillar attachment portion 311 and the fixing portion 11 in the depth direction B of the car room is eliminated, and the gap between the first pillar attachment portion 312 and the fixing portion 21 in the depth direction B of the car room is eliminated. Accordingly, the gap between the second column attachment portion 321 and the fixing portion 11 in the depth direction B of the car room is increased, and the gap between the second column attachment portion 322 and the fixing portion 21 in the depth direction B of the car room is increased.
Then, the fixing part 11 is fixed to the second column mounting part 321 with a plurality of fasteners 12, and the fixing part 21 is fixed to the second column mounting part 322 with a plurality of fasteners 22. At this time, the vertical column 3 deforms so that the gap between the second column mounting part 321 and the fixing part 11 and the gap between the second column mounting part 322 and the fixing part 21 disappear. Further, at this time, since the rigidity of the first column mounting part 311 is higher than that of the second column mounting part 321, and the rigidity of the first column mounting part 312 is higher than that of the second column mounting part 322, the amount of deformation of the first column mounting part 311 is smaller than that of the second column mounting part 321, and the amount of deformation of the first column mounting part 312 is smaller than that of the second column mounting part 322. Therefore, the vertical column 3 can be deformed so that the gap between each of the pair of fixing portions 11 and the vertical column 3 and the gap between each of the pair of fixing portions 21 and the vertical column 3 disappear in a state where the vertical column 3 extends in the vertical direction.
As described above, according to the elevator car frame device of the third embodiment of the present invention, since the groove 342 is formed in the insertion portion 34 and the groove 342 is disposed between the first pillar mounting portion 311 and the second pillar mounting portion 321 in the depth direction B of the car room, the first pillar mounting portion 311 and the second pillar mounting portion 321 can be formed with a simple configuration. Further, since the groove 352 is formed in the insertion portion 35 and the groove 352 is disposed between the first column attachment portion 312 and the second column attachment portion 322 in the depth direction B of the car room, the first column attachment portion 312 and the second column attachment portion 322 can be formed with a simple configuration.
Further, since the groove 342 is disposed so as to extend in the height direction and so as to be offset in the depth direction B from the center of the insertion portion 34 in the depth direction B of the car compartment, the first column mounting portion 311 and the second column mounting portion 321 can be formed with a simple configuration. Further, since the groove 352 is disposed so as to extend in the height direction and so as to be offset in the depth direction B from the center of the insertion portion 35 in the depth direction B of the car compartment, the first column mounting portion 312 and the second column mounting portion 322 can be formed with a simple configuration.
In each of the above embodiments, the first column attachment portion 311 and the second column attachment portion 321 have different rigidities in the depth direction B in the portion of the vertical column 3 sandwiched between the pair of fixing portions 11, and the first column attachment portion 312 and the second column attachment portion 322 have different rigidities in the depth direction B in the portion of the vertical column 3 sandwiched between the pair of fixing portions 21. For example, a structure is also possible in which: in the portion of the column 3 sandwiched between the pair of fixing portions 11, the first column mounting portion 311 and the second column mounting portion 321 each have different rigidity in the depth direction B, and in the portion of the column 3 sandwiched between the pair of fixing portions 21, the first column mounting portion 312 and the second column mounting portion 322 each have the same rigidity in the depth direction B. Further, the structure may be such that: in the portion of the column 3 sandwiched between the pair of fixing portions 11, the rigidity of each of the first column mounting portion 311 and the second column mounting portion 321 in the depth direction B is the same, and in the portion of the column 3 sandwiched between the pair of fixing portions 21, the rigidity of each of the first column mounting portion 312 and the second column mounting portion 322 in the depth direction B is different.
Embodiment IV
Fig. 10 is a front view showing an elevator car frame device according to a fourth embodiment of the present invention, fig. 11 is a side view showing the elevator car frame device of fig. 10, and fig. 12 is a cross-sectional view taken along line XII-XII of fig. 10 and shown in the direction of an arrow. In the third embodiment, a description has been given of a structure in which the vertical column 3 is formed of one member and the groove 342 and the groove 352 are formed in the vertical column 3. The structure of the third embodiment is suitable for an elevator car frame device for a small-sized elevator or an elevator car frame device for a small-sized elevator in which the grooves 342 and the grooves 352 can be formed in the vertical column 3. The configuration of the fourth embodiment is suitable for an elevator car frame device for a small-sized elevator or an elevator car frame device for a small-sized elevator in which the grooves 342 and 352 cannot be formed in the vertical column 3.
The underbeam 1 has a pair of fixing portions 11 that sandwich the lower end portions of the vertical columns 3 in the depth direction B of the car room. One of the pair of fixing portions 11 includes a fixing portion body 111 and a reinforcing portion 112, and the reinforcing portion 112 is provided in the fixing portion body 111 and reinforces the fixing portion body 111. The other of the pair of fixing portions 11 does not include a reinforcing portion. Therefore, the pair of fixing portions 11 are respectively different in rigidity from each other. One of the pair of fixing portions 11 is a fixing portion 11A, and the other is a fixing portion 11B.
Specifically, the ratio of the rigidity of the one fixing portion 11A of the pair of fixing portions 11 to the rigidity of the other fixing portion 11B in the depth direction B of the car room is, for example, about 5:1 to 10: 1.
The upper beam 2 has a pair of fixing portions 21 that sandwich the upper end portions of the vertical columns 3 in the depth direction B of the car room. The pair of fixing portions 21 are different from the fixing portions 11A, and do not include a reinforcing portion. Therefore, the pair of fixing portions 21 are each rigid and the same. One of the pair of fixing portions 21 is a fixing portion 21A, and the other is a fixing portion 21B.
The vertical column 3 has an insertion portion 34 inserted between the pair of fixing portions 11. The insertion portion 34 includes: a first post mounting portion 311 fixed to one of the pair of fixing portions 11 by a fastener 12; and a second column mounting portion 321 fixed to the other of the pair of fixing portions 11 by a fastener 12. The first column mounting part 311 and the second column mounting part 321 are integral with each other.
The vertical column 3 has an insertion portion 35 inserted between the pair of fixing portions 21. The insertion portion 35 includes: a first column mounting portion 312 fixed to one of the pair of fixing portions 21 by a fastener 22; and a second column mounting part 322 fixed to the other of the pair of fixing parts 11 by a fastener 22. The first column mounting part 312 and the second column mounting part 322 are integral with each other. The other structure is the same as in the first embodiment.
Next, the procedure of assembling the elevator car frame device will be described. First, the lower end of the vertical column 3 is inserted between the pair of fixing portions 11, and the upper end of the vertical column 3 is inserted between the pair of fixing portions 21. In order to easily fit the vertical column 3 between the pair of fixing portions 11, a gap is formed between each of the pair of fixing portions 11 and the vertical column 3. Further, in order to easily fit the vertical column 3 between the pair of fixing portions 21, a gap is formed between each of the pair of fixing portions 21 and the vertical column 3.
Then, the fixing portion 11A is fixed to the first post mounting portion 311 with a plurality of fasteners 12, and the fixing portion 21A is fixed to the first post mounting portion 312 with a plurality of fasteners 22. When the fixing portion 11A is fixed to the first pillar attaching portion 311 and the fixing portion 21A is fixed to the first pillar attaching portion 312, the gap between the first pillar attaching portion 311 and the fixing portion 11A in the depth direction B of the car room is eliminated, and the gap between the first pillar attaching portion 312 and the fixing portion 21A in the depth direction B of the car room is eliminated. Thus, the gap between the second column attachment portion 321 and the fixing portion 11B in the depth direction B of the car room is increased, and the gap between the second column attachment portion 322 and the fixing portion 21B in the depth direction B of the car room is increased.
Then, the fixing portion 11B is fixed to the second column mounting portion 321 with a plurality of fasteners 12, and the fixing portion 21B is fixed to the second column mounting portion 322 with a plurality of fasteners 22. At this time, the vertical column 3 deforms so that the gap between the second column mounting part 321 and the fixing part 11B and the gap between the second column mounting part 322 and the fixing part 21B disappear. At this time, since the rigidity of the fixing portion 11A is higher than that of the fixing portion 11B, the amount of deformation of the fixing portion 11A is smaller than that of the fixing portion 11B. Therefore, the vertical column 3 can be deformed such that the gap between each of the pair of fixing portions 11 and the vertical column 3 disappears in the state where the vertical column 3 extends in the vertical direction.
As described above, according to the elevator car frame device of the fourth embodiment of the present invention, since the rigidity of the fixing portion 11A of the pair of fixing portions 11 is higher than the rigidity of the fixing portion 11B, when the pair of fixing portions 11 are fixed to the vertical column 3 by the fastening tool 12, the fixing portion 11A deforms less than the fixing portion 11B. Therefore, by fixing the fixing portion 11A to the first column attachment portion 311, the pair of fixing portions 11 can be deformed such that the gap between the pair of fixing portions 11 and the vertical column 3 disappears in a state where the vertical column 3 extends in the vertical direction. Thus, trial and error of the fastening amounts of the fasteners 12 and the fastening order of the fasteners 12 do not have to be repeated. As a result, the efficiency of the assembly work of the elevator car frame device can be improved.
In the fourth embodiment, the structure in which the fixing portion 11A includes the reinforcing portion 112 and the fixing portion 11B, the fixing portion 21A, and the fixing portion 21B do not include the reinforcing portion has been described, but the present invention is not limited thereto. For example, a structure is also possible in which: the fixing portion 11A and the fixing portion 21A each include a reinforcing portion, and the fixing portion 11B and the fixing portion 21B do not include a reinforcing portion. Further, the structure may be such that: the fixing portion 21A includes a reinforcing portion, and the fixing portions 11A, 11B and 21B do not include a reinforcing portion.
In each of the above embodiments, the fixing of the lower beam 1 and the vertical column 3 and the fixing of the upper beam 2 and the vertical column 3 in the elevator car frame device have been described, but the present invention may be applied to the fixing of other devices. Examples of the fixing of the other devices include fixing of a vertical frame and an upper frame and fixing of a vertical frame and a lower frame in a counterweight frame for an elevator.
