The main rope 3 is wound around the car-side sheave 2a, the sheave of the hoisting machine 4, and the counterweight-side sheave 5a in this order from one end.
The other end of the main rope 3 extending upward in the hoistway from the counterweight-side sheave 5a is attached to the upper portion of the hoistway in the same manner as the one end. The car 2 and the counterweight 5 are driven by the hoisting machine 4 to move up and down in the hoistway.
2. Example of Car construction
Fig. 2 is a front view showing the car 2 in the car room.
As shown in fig. 1 and 2, the car 2 includes a floor assembly 10 serving as a floor of a car room, a side plate 11, a ceiling plate 12, a door 13, and a frame 16 (see fig. 3). The bottom plate assembly 10 and the top plate 12 are disposed to face each other in the vertical direction. The side plates 11 are erected around the bottom plate assembly 10 and the top plate 12. Further, of the side plates 11 surrounding the periphery of the floor assembly 10, a front side plate 14 disposed on the front side of the car 2 is provided with an entrance 14a. An operation panel, a display unit, and the like, not shown, are attached to the front side plate 14 in accordance with the design specifications of the customer. The size of the doorway 14a may be variously changed according to the design specifications of the customer. Therefore, the thickness and size of the front side panel 14 can be variously changed according to the design specifications of customers.
Further, a door section 13 is openably and closably provided at an entrance 14a provided in the front side plate 14. The floor assembly 10, the side plate 11, the ceiling plate 12, the front side plate 14, and the door 13 constitute a car room for people and cargo in the car 2.
Fig. 3 and 4 are perspective views showing the floor assembly 10 and the housing 16, and fig. 5 is a side view showing the floor assembly 10 and the housing 16.
As shown in fig. 3 to 5, the floor panel assembly 10 is supported by the frame 16. The frame 16 includes 2 vertical frames extending in the vertical direction and a horizontal frame extending in the width direction, i.e., the left-right direction. Further, a car-side sheave 2a is attached to a lower portion of the frame 16 in the vertical direction.
Fig. 6 and 7 are perspective views showing the bottom plate assembly 10. Fig. 8 isbase:Sub>A front view showing the bottom plate assembly 10, and fig. 9 isbase:Sub>A sectional view taken along linebase:Sub>A-base:Sub>A shown in fig. 8.
As shown in fig. 6 to 9, the floor panel assembly 10 has a floor panel main body 21, a fixing bracket 23, and a floor panel 22. The bottom panel 22 is placed on the top surface of the bottom panel main body 21 and the fixing bracket 23 in the vertical direction. The floor main body 21 is formed in a substantially rectangular shape. The bottom plate main body 21 is supported by the frame 16 (see fig. 3 and 4). The floor body 21 is set to have the same size as the floor bodies of the other cars. The floor main body 21 is shared with floor main bodies of other cars.
The fixing bracket 23 is fixed to a front surface portion, which is a front end portion in the front-rear direction of the bottom plate main body 21, via a fixing bolt 35. The fixing bracket 23 is formed of an elongated member extending in the left-right direction orthogonal to the front-rear direction. The length of the fixing bracket 23 in the left-right direction is set to be substantially the same as the length of the bottom plate main body 21 in the left-right direction.
Fig. 10 and 11 are views showing a state in which the rocker 42, the side plate 11, and the front side plate 14 are provided in the floor panel assembly 10.
As shown in fig. 10 and 11, the rocker bracket 41 is fixed to a front surface portion in the front-rear direction, which is a surface of the fixing bracket 23 opposite to the surface facing the floor main body 21. A rocker 42 that movably supports the door portion 13 is provided on an upper surface portion in the vertical direction of the rocker bracket 41. That is, the rocker 42 is fixed to the floor main body 21 via the fixing bracket 23.
As shown in fig. 10 and 11, a plurality of side plates 11 and a front side plate 14 are attached to an upper surface portion in the vertical direction of the bottom plate assembly 10. The plurality of side plates 11 are attached to an outer edge portion of the bottom plate main body 21 in the bottom plate assembly 10. In addition, the plurality of side plates 11 are attached to 3 outer edge portions of the 4 outer edge portions of the bottom plate main body 21 except the front surface portion.
The front side plate 14 provided with the doorway 14a and the operation panel is mounted on the side plate 11 and attached to the fixed bracket 23. The fixing bracket 23 is formed in cooperation with the dimensions of the threshold 42 and the front side panel 14. Thus, when the dimensions of the rocker 42 and the front side plate 14 are changed, the dimension of the fixing bracket 23 may be changed in the floor panel assembly 10, and the dimension of the floor panel main body 21 does not need to be changed. That is, even if the size of the front side plate 14 varies, the floor main body 21 can be used in common with floor main bodies of different cars. As a result, the car 2 that can flexibly cope with the use change of the customer can be provided.
Further, since the rocker 42 is fixed to the floor main body 21 via the fixing bracket 23, when a load is applied to the rocker 42, a large bending moment occurs in the fixing bracket 23. Therefore, as shown in fig. 6, 7, and 9, a plurality of reinforcing members 31 are provided on the fixing bracket 23. The plurality of reinforcing members 31 are provided at intervals in the lateral direction of the fixing bracket 23, that is, the width direction. The reinforcing member 31 is provided at least at a position corresponding to the doorway 14a through which people and cargo enter and exit the fixed bracket 23.
Next, the detailed structure of the fixing bracket 23 and the reinforcing member 31 will be described with reference to fig. 12 and 13.
Fig. 12 is an enlarged cross-sectional view of the fixing bracket 23. Fig. 13 is a plan view of the fixing bracket 23 and the rocker 42 as viewed from below in the up-down direction.
As shown in fig. 12 and 13, the fixing bracket 23 has a first fixing surface portion 25, a second fixing surface portion 26, a lower surface portion 27, and an upper surface portion 28. The first fixing surface portion 25 and the second fixing surface portion 26 are opposed to each other in the front-rear direction. The first fixing surface portion 25 is fastened and fixed to the front surface portion of the bottom plate main body 21 via a fixing bolt 35. The rocker bracket 41 is fastened and fixed to the second fixing surface portion 26 via the fixing bolt 35. The first fixing surface portion 25 and the second fixing surface portion 26 are arranged in parallel to the vertical direction.
The upper end portions of the first fixing surface portion 25 and the second fixing surface portion 26 in the vertical direction are connected to an upper surface portion 28 at a right angle. The bottom panel 22 can be placed on the upper surface 28. Therefore, the fixing bracket 23 is formed in a shape cut in the vertical direction into a substantially コ letter shape. Further, at the lower end portion in the vertical direction of the second fixing surface portion 26, a lower surface portion 27 is connected to the second fixing surface portion 26 at a right angle. The lower surface portion 27 protrudes from the lower end portion of the second fixing surface portion 26 toward the first fixing surface portion 25. The lower surface portion 27 and the upper surface portion 28 face each other in the vertical direction.
The reinforcing member 31 is inserted between the first fixing surface portion 25 and the second fixing surface portion 26 in the fixing bracket 23. The reinforcing member 31 is fastened and fixed to the fixing bracket 23 by a fixing bolt 35.
Here, a case where the reinforcing member 31 is fixed in the horizontal direction, that is, fixed to the first fixing surface portion 25 and the second fixing surface portion 26 will be described. In order to insert the reinforcing member 31 between the first fixing surface portion 25 and the second fixing surface portion 26 in the fixing bracket 23, the length of the reinforcing member 31 in the front-rear direction needs to be slightly shorter than the distance between the first fixing surface portion 25 and the second fixing surface portion 26. When the fixing bolt 35 is tightened when the reinforcing member 31 is fastened and fixed, the first fixing surface portion 25 and the second fixing surface portion 26 are deformed in a direction to approach each other. Therefore, the first fixing surface portion 25 and/or the second fixing surface portion 26 are inclined with respect to the up-down direction. As a result, the rocker 42 fixed to the second fixing surface portion 26 is inclined with respect to the horizontal direction, and the front end portion of the rocker 42 in the front-rear direction hangs down in the up-down direction.
In contrast, in the car 2 of this example, the reinforcing member 31 is fixed to the fixed bracket 23 with 2 shafts in different directions. The detailed structure of the reinforcing member 31 and the method of fixing the reinforcing member 31 in the car 2 of this example will be described below.
The reinforcing member 31 is formed in a substantially right-angled triangular shape when viewed from the left-right direction. The reinforcing member 31 has a first surface 31a and a second surface 31b. The first surface 31a is a lower surface of the reinforcing member 31 in the vertical direction. The second surface 31b is connected to an end portion of the first surface 31a on the rear end side in the front-rear direction. The second surface 31b is bent upward in the vertical direction substantially perpendicularly from the end of the first surface 31 a.
When the reinforcing member 31 is inserted between the first fixing surface portion 25 and the second fixing surface portion 26 of the fixing bracket 23, the first surface portion 31a faces the lower surface portion 27 of the fixing bracket 23, and the second surface portion 31b faces the first fixing surface portion 25 of the fixing bracket 23. The first surface portion 31a is fastened and fixed to the lower surface portion 27 via a fixing bolt 35, and the second surface portion 31b is fastened and fixed to the first fixing surface portion 25 via a fixing bolt 35. That is, the reinforcing member 31 is fixed to the fixing bracket 23 at 2 of the first fixing surface portion 25 and the lower surface portion 27. Thereby, the reinforcing member 31 is fixed between the first fixing surface portion 25 and the second fixing surface portion 26 in the fixing bracket 23.
As described above, the first surface 31a and the second surface 31b fixed to the fixing bracket 23 are orthogonal to each other. That is, the 2 fixing bolts 35 that fix the reinforcing member 31 are arranged so that their axial directions are orthogonal to each other. When the 2 fixing bolts 35 attached to the first surface portion 31a and the second surface portion 31b are fastened, the fixing bracket 23 is loaded by the fixing bolts 35 on the first fixing surface portion 25 and the lower surface portion 27 perpendicular to the first fixing surface portion 25. Therefore, even if 2 fixing bolts 35 are tightened, the interval between the first fixing surface portion 25 and the second fixing surface portion 26 does not change.
Thus, even when the reinforcing member 31 is fixed to the fixing bracket 23, the first fixing surface portion 25 and the second fixing surface portion 26 can be kept parallel to each other in the vertical direction. As a result, the rocker 42 fastened and fixed to the second fixing surface portion 26 via the fixing bolt 35 can be prevented from inclining with respect to the horizontal direction.
Further, by fixing the reinforcement member 31 inside the fixed bracket 23, even when a load is applied to the rocker 42, the fixed bracket 23 can be prevented from being deformed by a bending moment.
In the car 2 of this example, the second surface 31b of the reinforcing member 31 is fixed to the first fixed surface portion 25 of the fixed bracket 23, but the present invention is not limited thereto, and the second surface 31b may be fixed to the second fixed surface portion 26 of the fixed bracket 23. In addition, although the example in which the lower surface portion 27 of the first surface portion 31a of the fixing reinforcing member 31 in the fixing bracket 23 is formed on the second fixing surface portion 26 side has been described, the present invention is not limited thereto, and the lower surface portion 27 may be formed on the first fixing surface portion 25 side.
Further, although the reinforcing member 31 is formed in a substantially right triangle shape, the present invention is not limited thereto, and may be formed in various shapes such as a square shape or a コ font shape. In addition, although the example in which the axial directions of the 2 fixing bolts 35 fixing the reinforcing member 31 are orthogonal has been described, the present invention is not limited to this, and the axial directions of the 2 fixing bolts 35 may intersect with each other.
The present invention is not limited to the embodiments described above and shown in the drawings, and can be variously modified and implemented without departing from the scope of the present invention.
In the above embodiment, the example in which the fixing bolt is applied as an example of the fixing member has been described, but the present invention is not limited to this, and a rivet may be applied as the fixing member.
The present invention can also be applied to a multi-car elevator in which a plurality of cars move up and down in one hoistway.
In the present specification, terms such as "parallel" and "orthogonal" are used, but they do not mean "parallel" and "orthogonal" strictly, and may be in a state of "substantially parallel" and "substantially orthogonal" within a range capable of functioning including "parallel" and "orthogonal".
