1. Configuration of Elevator First, a configuration of an elevator according to an embodiment of the present invention (hereinafter, referred to as “present example”) will be described with reference to FIGS. 1 and 2.
1 and 2 are schematic configuration diagrams illustrating a configuration example of the elevator of the present example.

  As shown in FIGS. 1 and 2, the elevator 1 of the present example is provided on a hoistway 110 formed in a building structure 200. The elevator 1 includes a car 120 on which people and luggage are placed, a main rope 130, a counterweight 140, a warp wheel 150, and a hoist 100. The hoistway 110 is formed in the building structure 200, and a machine room 160 is provided at the top. In the machine room 160, the hoisting machine support mechanism 10 is installed.

  The hoist 100 and the warp wheel 150 are supported by a hoist support mechanism 10 provided in a machine room 160. The hoist 100 has a sheave 101 around which a main rope 130 is wound, a drive part 102 for driving the sheave 101 to rotate, and a base part 103 for supporting the sheave 101 and the drive part 102. The detailed configurations of the hoisting machine support mechanism 10, the hoisting machine 100, and the warp wheel 150 will be described later. A main rope 130 is wound around the sheave 101 and the warp wheel 150 of the hoisting machine 100.

  The car 120 is arranged in the hoistway 110. A car-side pulley 121 is provided at an upper end of the car 120. The car-side pulley 121 is set to have a diameter L1. Similarly, a weight side pulley 141 is provided at the upper end of the counterweight 140. The car-side pulley 121 and the weight-side pulley 141 are arranged so that their axial directions are orthogonal to the axial directions of the sheave 101 and the deflector wheel 150 of the hoisting machine 100.

  At both ends in the axial direction of the main rope 130, rope adjustment members 131 for adjusting the tension of the main rope 130 are provided. Both ends of the main rope 130 are fixed to a rope support mechanism 20 provided in the machine room 160 via a rope adjustment member 131. The detailed configurations of the rope adjustment member 131 and the rope support mechanism 20 will be described later.

  The main rope 130 descends vertically in the hoistway 110 from one end in the axial direction, is wound around the car-side pulley 121, and is then wound around the sheave 101 and the warp wheel 150 of the hoisting machine 100. . The main rope 130 is wound around the sheave 101 and the warp wheel 150 of the hoisting machine 100, and then is wound around the pulley 141 on the weight side. After the main rope 130 is wound around the pulley 141 on the weight side, the other end in the axial direction is fixed to the rope support mechanism 20 provided in the machine room 160 via the rope adjusting member 131.

  Thus, when the hoist 100 is driven, the car 120 and the counterweight 140 move up and down in the hoistway 110 via the main rope 130.

2. Next, the configurations of the hoisting machine support mechanism 10 and the rope supporting mechanism 20 will be described with reference to FIGS.
FIG. 3 is a front view showing a state around the hoist 100, and FIG. 4 is a plan view showing a state around the hoist 100. FIG. 5 is a sectional view taken along line TT shown in FIG. 3, and FIG. 6 is a sectional view taken along line SS shown in FIG.

[Hoist support mechanism]
First, the hoisting machine support mechanism 10 will be described. As shown in FIGS. 3 and 4, the hoisting machine support mechanism 10 includes a spacer 11 placed on the floor 161 of the machine room 160, a first machine beam 12A, and a second machine beam 12B. ing. The spacer 11, the first machine beam 12A, and the second machine beam 12B are so-called H-section steels whose H-shaped cross section in the vertical direction is formed.

  The spacer 11 is placed on the floor 161 via the vibration isolating member 40. The spacer 11 is arranged such that the extending direction is substantially parallel to the axial direction of the sheave 101 of the hoisting machine 100. The height of the hoisting machine 100 in the vertical direction is adjusted by the spacer 11. The first machine beam 12A and the second machine beam 12B are fixed to the upper portion of the spacer 11 by a fixing method such as a fixing bolt or welding.

  The first machine beam 12A and the second machine beam 12B are arranged so that their extending directions are parallel to each other and orthogonal to the direction in which the spacer 11 extends. Further, the first machine beam 12A and the second machine beam 12B are arranged at predetermined intervals in the direction in which the spacer 11 extends.

  The base 103 of the hoisting machine 100 is attached to the upper part of the first machine beam 12A and the second machine beam 12B via a vibration isolating member 41. A support member 151 and a pulley beam 152 are provided on the lower surface of the base 103 in the hoisting machine 100 in the vertical direction. A warp wheel 150 is rotatably supported by the support member 151 and the pulley beam 152. The warp wheel 150 is disposed between the first machine beam 12A and the second machine beam 12B. Then, the main rope 130 wound around the sheave 101 and the warp wheel 150 passes between the first machine beam 12A and the second machine beam 12B.

A rope supporting mechanism that supports the main rope 130 via a rope adjusting member 131 below the hoisting machine 100 supported by the hoisting machine supporting mechanism 10 in the vertical direction and near the second machine beam 12B. 20 are arranged.
[Rope adjustment member]
Here, the rope adjusting member 131 will be described.
As shown in FIGS. 1 and 2, the rope adjusting members 131 are provided at both ends in the axial direction of the main rope 130. As shown in FIG. 6, the rope adjustment member 131 has a thimble rod 132, a spring member 133, a nut 134, a first spring seat 135, and a second spring seat 136.

  The thimble rod 132 is formed in a rod shape, and is fixed to an end of the main rope 130. A male screw is formed on the outer peripheral surface of the thimble rod 132. The thimble rod 132 passes through a through hole 21b and an auxiliary through hole 22d of the rope support mechanism 20 described below from below in the vertical direction. A spring member 133, a nut 134, a first spring seat 135, and a second spring seat 136 are attached to a vertical upper portion of the thimble rod 132 exposed from the rope support mechanism 20.

  The first spring seat 135 is in contact with the upper end of the spring member 133 in the vertical direction, and the second spring seat 136 is in contact with the lower end of the spring member 133 in the vertical direction. The second spring seat 136 is placed on the upper surface of the main surface 22a of the auxiliary plate 22 of the rope support mechanism 20, which will be described later.

  The nut 134 is screwed to the distal end side of the thimble rod 132, that is, the upper end side in the vertical direction, relative to the first spring seat 135. By adjusting the position at which the nut 134 is screwed into the thimble rod 132, the amount of expansion and contraction of the spring member 133 disposed between the first spring seat 135 and the second spring seat 136 can be set. Thereby, the tension of the main rope 130 is adjusted. Further, the load applied to the thimble rod 132 is applied to a rope support mechanism 20 described later via a spring member 133.

[Rope support mechanism]
Next, the rope support mechanism 20 will be described. As shown in FIG. 3, the rope support mechanism 20 includes a second machine beam 12B, a rope support beam 13, two support plates 21 and 21, and two auxiliary plates 22 and 22. In the present example, the second machine beam 12B constituting the hoisting machine support mechanism 10 also serves as the rope support beam of the rope support mechanism 20. Thus, the number of support beams installed on the top of the hoistway 110 can be reduced.

  The rope support beam 13 is made of an H-shaped steel, like the first machine beam 12A and the second machine beam 12B. Here, the configurations of the second machine beam 12B and the rope support beam 13 will be described.

  As shown in FIG. 6, the second machine beam 12B has an upper flange portion 14, a lower flange portion 15, and a connecting portion 16 that connects the upper flange portion 14 and the lower flange portion 15. The lower flange portion 15 is composed of a first flange piece 15a and a second flange piece 15b that are substantially continuous from the connecting portion 16. The first flange piece 15a and the second flange piece 15b protrude from the lower end of the joint 16 in opposite directions.

  Further, the rope support beam 13 has an upper flange portion 17, a lower flange portion 18, and a connecting portion 19 for connecting the upper flange portion 17 and the lower flange portion 18. The lower flange portion 18 is composed of a first flange piece 18a and a second flange piece 18b that extend substantially perpendicularly from the coupling portion 19. The first flange piece 18a and the second flange piece 18b protrude from the lower end of the connecting portion 19 in opposite directions.

  As shown in FIG. 4, the rope support beam 13 is fixed on the upper part of the spacer 11 similarly to the first machine beam 12A and the second machine beam 12B. Further, the rope supporting beam 13 is arranged so that its extending direction is substantially parallel to the direction in which the first machine beam 12A and the second machine beam 12B extend. Further, the rope support beam 13 is arranged at a predetermined interval on the opposite side of the second machine beam 12B from the first machine beam 12A. The distance between the rope support beam 13 and the second machine beam 12B is set according to the diameter L1 of the car-side pulley 121 (see FIG. 2).

  Two support plates 21 and 21 and two auxiliary plates 22 and 22 are arranged on the second machine beam 12B and the rope support beam 13. One end of the main rope 130 in the axial direction is fixed to one of the two support plates 21 and 21 via the rope adjusting member 131, and the other end of the main rope 130 is fixed to the other end in the other direction. It is fixed via a rope adjusting member 131.

  As shown in FIGS. 5 and 6, the support plate 21 is formed in a substantially flat plate shape. Further, the support plate 21 is arranged so as to connect the lower flange portion 15 of the second machine beam 12B and the lower flange portion 18 of the rope support beam 13. The upper surface 21a of the support plate 21 in the vertical direction contacts the lower flange portion 15 of the second machine beam 12B and the lower surface of the lower flange portion 18 of the rope support beam 13 in the vertical direction.

  The support plate 21 is fixed to the lower flange portions 15 and 18 by a fixing member 25 including a fixing bolt 25A and a fixing nut 25B. Thereby, the load applied to the support plate 21 is distributed to the second machine beam 12B and the rope support beam 13. As a result, the size of the second machine beam 12B and the rope support beam 13 can be reduced.

  Further, one end of the support plate 21 on the second machine beam 12B side is fastened and fixed to both the first flange piece 15a and the second flange piece 15b of the lower flange portion 15 by a fixing member 25. The other end of the support plate 21 on the side of the rope support beam 13 is fastened and fixed to both the first flange piece 18a and the second flange piece 18b of the lower flange portion 18 by a fixing member 25. That is, the support plate 21 is fixed to both of the flange pieces 15a, 15b, 18a, 18b projecting from both sides of the coupling portions 16, 19 in the lower flange portions 15, 18.

  Therefore, the load applied to the lower flange portions 15 and 18 via the support plate 21 is distributed to both the first flange pieces 15a and 18a and the second flange pieces 15b and 18b. Thus, it is possible to prevent a load from being applied to only one of the two flange pieces 15a, 15b, 18a, 18b constituting the lower flange portions 15, 18, and to suppress deformation of the loaded flange piece. can do. Further, the loads applied to the lower flange portions 15 and 18 can be transmitted to the coupling portions 16 and 19 in a well-balanced manner.

  Thus, by applying a load to the second machine beam 12B and the rope support beam 13 in a well-balanced manner, the size of the second machine beam 12B and the rope support beam 13 can be reduced.

  Further, the support plate 21 has a plurality of through holes 21b. The plurality of through holes 21b penetrate the support plate 21 in the vertical direction. Further, the plurality of through holes 21b are formed in the support plate 21 in a staggered manner. The position where the plurality of through holes 21b are provided is set in accordance with the diameter L1 of the car-side pulley 121 and the diameter of the weight-side pulley 141.

Further, the plurality of through holes 21b are formed such that the support plate 21 avoids the places where the plurality of through holes 21b are in contact with the second machine beam 12B and the rope support beam 13. That is, the plurality of through holes 21 b are formed between the second machine beam 12 </ b> B and the rope support beam 13 in the support plate 21. The thimble rod 132 of the rope adjusting member 131 penetrates the through hole 21b.

  In this manner, the location where the thimble rod 132, which is the end of the main rope 130, is attached is the support plate 21 disposed between the second machine beam 12B and the rope support beam 13. That is, the thimble rod 132 is not disposed between the upper flange portion 14 and the lower flange portion 15 of the second machine beam 12B or between the upper flange portion 17 and the lower flange portion 18 of the rope support beam 13. As a result, the vertical lengths of the coupling portions 16 and 19 of the second machine beam 12B and the rope support beam 13 can be designed without being restricted by the thimble rod 132, and the second machine beam 12B and the rope support beam 13 can be designed. The size of the beam 13 can be reduced.

  Further, by reducing the size of the second machine beam 12B and the rope support beam 13, it is possible to save space in the machine room 160 in which the second machine beam 12B and the rope support beam 13 are installed. Further, even when the space of the machine room 160 provided at the top of the hoistway 110 is narrow, the rope support mechanism 20 can be disposed, and the end of the main rope 130 can be supported.

  Above the rope adjustment member 131 attached to the support plate 21 in the vertical direction, no support beam is arranged and the support beam is open. As a result, a space is secured above the rope adjustment member 131 in the vertical direction, and the work of attaching the rope adjustment member 131 and the work of adjusting the tension of the main rope 130 by the rope adjustment member 131 can be easily performed.

  An auxiliary plate 22 is placed on the upper surface 21a on the upper side in the vertical direction of the support plate 21. The auxiliary plate 22 is formed in a substantially flat shape. The auxiliary plate 22 has a main surface portion 22a formed in a rectangular shape, and two auxiliary support pieces 22b and 22c.

  The main surface portion 22a is placed between the second machine beam 12B and the rope support beam 13 on the upper surface 21a of the support plate 21. A plurality of auxiliary side through holes 22d are formed in the main surface portion 22a.

  The auxiliary side through hole 22d penetrates the main surface portion 22a in the vertical direction. The auxiliary through hole 22d is formed at a position facing the through hole 21b provided in the support plate 21 when the main surface portion 22a is placed on the upper surface 21a of the support plate 21. The auxiliary side through-hole 22d communicates with the through-hole 21b of the support plate 21. The thimble rod 132 of the rope adjusting member 131 penetrates the auxiliary side through hole 22d. The second spring seat 136 of the rope adjusting member 131 is placed on the main surface portion 22a, and a load from the thimble rod 132 is applied to the main surface portion 22a.

  A first auxiliary support piece 22b is provided at an end of the second machine beam 12B on the main surface 22a. A second auxiliary support piece 22c is provided at an end of the rope support beam 13 on the main surface 22a.

  The first auxiliary support piece 22b protrudes from the end of the main surface portion 22a on the second machine beam 12B side toward the second machine beam 12B. The second auxiliary support piece 22c protrudes from the end of the main surface portion 22a on the rope support beam 13 side toward the rope support beam 13.

  When the auxiliary plate 22 is placed on the upper surface 21a of the support plate 21, the first auxiliary support piece 22b is disposed above the second flange piece 15b of the lower flange portion 15 in the second machine beam 12B in the vertical direction. Normally, a gap 29 is formed between the first auxiliary support piece 22b and the second flange piece 15b. The second auxiliary support piece 22c is disposed above the first flange piece 18a of the lower flange portion 18 of the rope support beam 13 in the vertical direction. In a normal state, a gap 29 is formed between the second auxiliary support piece 22c and the first flange piece 18a, similarly to the first auxiliary support piece 22b.

  In normal times, the load from the thimble rod 132 applied to the auxiliary plate 22 is transmitted to the support plate 21 via the main surface portion 22a. As a result, it is possible to prevent a load from being applied from the first auxiliary support piece 22b and the second auxiliary support piece 22c to one of the flange pieces 15b and 18a of the lower flange parts 15 and 18 in a normal state. 15 and 18 can be prevented from being deformed.

  Further, a notch 22f is formed at a corner of the first auxiliary support piece 22b and the second auxiliary support piece 22c. The formation of the cutout portion 22f can prevent the first auxiliary support piece 22b and the second auxiliary support piece 22c from interfering with the fixing nut 25B of the fixing member 25 that fixes the support plate 21.

  The auxiliary plate 22 is fixed to the support plate 21 by a plate fixing member 27 including a fixing bolt 27A and a fixing nut 27B.

  When the fixing bolt 25A for fixing the support plate 21 to the second machine beam 12B or the rope support beam 13 is broken, the first auxiliary support piece 22b and the second auxiliary support piece 22c are connected to the flanges of the lower flange portions 15 and 18. It is placed on the pieces 15b and 18a. The auxiliary plate 22 is supported by the lower flange 15 of the second machine beam 12B and the lower flange 18 of the rope support beam 13. Thus, the load from the thimble rod 132 can be received by the auxiliary plate 22, the second machine beam 12B, and the rope support beam 13. As a result, even if the fixing bolt 25A is broken, it is possible to prevent the car 120 from dropping, and it is possible to enhance the safety of the elevator 1.

3. Next, an example of a method of attaching the main rope 130 using the rope support mechanism 20 having the above-described configuration will be described.
In addition, as shown in FIG. 4, a second machine beam 12B and a rope support beam 13 are previously installed in the machine room 160, and as shown in FIGS. The thimble rod 132 is attached in advance.

  First, as shown in FIGS. 5 and 6, the support plate 21 is disposed below the lower flange portion 15 of the second machine beam 12B and the lower flange portion 18 of the rope support beam 13. Next, as shown in FIG. 6, the upper surface 21a of the support plate 21 is brought into contact with the lower surfaces of the lower flange portions 15 and 18. Then, the support plate 21 is fixed to the lower surfaces of the lower flange portions 15 and 18 using the fixing bolts 25A and the fixing nuts 25B.

  Next, the main surface 22a of the auxiliary plate 22 is placed on the upper surface 21a of the support plate 21. At this time, a gap 29 is formed between the first auxiliary support piece 22b and the second flange piece 15b and between the second auxiliary support piece 22c and the first flange piece 18a. Then, the auxiliary plate 22 is fixed to the support plate 21 using the fixing bolt 27A and the fixing nut 27B. Thereby, the through hole 21b provided in the support plate 21 and the auxiliary side through hole 22d provided in the auxiliary plate 22 communicate with each other.

  Next, the thimble rod 132 attached to the end of the main rope 130 is inserted into the through hole 21b and the auxiliary through hole 22d from below in the vertical direction. Thus, the thimble rod 132 penetrates the through hole 21b and the auxiliary side through hole 22d, and the upper end protrudes upward from the auxiliary plate 22.

  Next, the spring member 133, the nut 134, the first spring seat 135, and the second spring seat 136 are attached to the upper end of the thimble rod 132 projecting from the auxiliary plate 22. At this time, no other member such as the upper flange portion of the support beam is arranged above the thimble rod 132 penetrating the support plate 21 and the auxiliary plate 22, and a sufficient space is secured. Therefore, the operation of attaching the spring member 133, the nut 134, the first spring seat 135, and the second spring seat 136 to the thimble rod 132 can be easily performed.

  Then, by attaching the spring member 133, the nut 134, the first spring seat 135, and the second spring seat 136 to the thimble rod 132, the attaching operation of the main rope 130 is completed.

  For example, in the above-described embodiment, an example has been described in which the second machine beam 12B of the hoisting machine support mechanism 10 is applied as one of the two rope support beams to which the support plate 21 is attached. However, the present invention is not limited to this. For example, one additional rope support beam may be provided. Alternatively, two machine beams 12A and 12B constituting the hoisting machine support mechanism 10 may be used as rope support beams.

  Furthermore, the example in which the hoisting machine 100 is installed in the machine room 160 provided at the top of the hoistway 110 has been described, but the present invention is not limited to this. For example, the hoisting machine 100 may be arranged at the bottom of the hoistway, and two driven pulleys around which the main rope is wound may be provided at the upper part of the hoistway. In this case, two rope support beams are installed at the top of the hoistway.

  In addition, the method of fixing the support plate to the beam is not limited to the fastening and fixing using the fixing nut and the fixing bolt, and various other fixing methods such as a fixing method using welding or a locking hook may be used. Good.
