The first weight guide rail 4 has a second beam attachment portion 22 and a third beam attachment portion 23 that are respectively located at the upper part in the hoistway 1. The 2nd beam attachment part 22 and the 3rd beam attachment part 23 are mutually separated about the up-down direction.

  The position of the first beam mounting portion 21 is set so as to avoid the position of the plurality of rail brackets and the position of the equipment in the hoistway (not shown) fixed to the first car guide rail 2. The positions of the second beam mounting portion 22 and the third beam mounting portion 23 are the positions of the plurality of rail brackets 20 and the position of the equipment in the hoistway (not shown) fixed to the first weight guide rail 4. Set to avoid.

  In this example, the first beam mounting portion 21, the second beam mounting portion 22, and the third beam mounting portion 23 are respectively present at positions lower than the position of the machine base 11. In this example, the position of the first beam mounting portion 21 is at the same height as the position of the second beam mounting portion 22. Furthermore, in this example, the third beam mounting portion 23 is positioned below the second beam mounting portion 22.

  The connection support 13 is attached to the first support beam 16 having a U-shaped cross section attached to the first beam attachment portion 21 and the second beam attachment portion 22, and is connected to the first support beam 16. A plate-like second support beam 17, and a plate-like third support beam 18 attached to the third beam attachment portion 23 and connected to the second support beam 17. In this example, the connection support 13 is disposed outside the respective areas of the car 6 and the counterweight 7 when viewed from above.

  One end of the first support beam 16 is attached to the first beam attachment portion 21 with a bolt and a rail clip. Thereby, the first support beam 16 is horizontally disposed along the depth direction of the hoistway 1. The position of the other end of the first support beam 16 is far from the position of the car back surface 6b when viewed from the landing 8. In this example, as viewed from above, as shown in FIG. 2, the first support beam 16 is disposed in a space between the first car side surface 6 c and the wall surface of the hoistway 1.

  One end of the second support beam 17 is attached to the second beam attachment portion 22 with a bolt and a rail clip. Accordingly, the second support beam 17 is horizontally disposed along the width direction of the hoistway 1. In this example, when viewed from above, as shown in FIG. 2, the second support beam 17 is disposed in a space between the car back surface 6 b and the wall surface of the hoistway 1. In this example, the other end of the second support beam 17 is attached to the other end of the first support beam 16 with a bolt.

  As shown in FIG. 3, one end of the third support beam 18 is attached to the third beam attachment portion 23 via a plate-like attachment member 24. The attachment member 24 is horizontally fastened to the third beam attachment portion 23 by bolts and rail clips. One end of the third support beam 18 is fastened to the mounting member 24 with a bolt.

  The other end of the third support beam 18 is fastened to the other end of the second support beam 17 with a bolt. Accordingly, the third support beam 18 is inclined with respect to the horizontal plane and the second support beam 17. Further, the third support beam 18 is inclined downward from the other end of the second support beam 17 toward the first weight guide rail 4. Thereby, the 2nd support beam 17 and the 3rd support beam 18 comprise the truss structure in the state attached to the 1st weight guide rail 4. FIG. In this example, when viewed from above, the third support beam 18 is disposed in a space between the car back surface 6 b and the wall surface of the hoistway 1.

  A plate-like fixing portion 25 is horizontally fixed to the first support beam 16. The fixing portion 25 is provided with a first rope stop portion 26. The first rope stopper 26 is disposed at a position away from the first car guide rail 2. In this example, as shown in FIG. 2, the distance L1 from the first rope stopper 26 to the first car guide rail 2 is such that the first rope stopper 26 and the first support beam 16 and the second It is smaller than the distance L2 to the connecting portion with the support beam 17. As shown in FIG. 1, the machine table 11 is provided with a second rope stopper 27.

  The car 6 and the counterweight 7 are suspended in the hoistway 1 by a plurality of cable-like bodies 30. As the cord-like body 30, for example, a rope or a belt is used. Each cord 30 has a first end 30 a connected to the first rope stop 26 and a second end 30 b connected to the second rope stop 27. As a result, the first end 30a is disposed on the upper part of the hoistway 1 while being supported by the machine base 11, and the second end 30b is supported by the first support beam 16 while being hoistway. 1 is arranged in the upper part. In this example, the first rope stop 26 and the first end 30 a are arranged at a position closer to the car back surface 6 b than the first car guide rail 2 in the depth direction of the hoistway 1.

  Each cord-like body 30 is wound around the pair of the car suspension wheel 9, the drive sheave 15, and the weight suspension wheel 10 in this order from the first end 30a, and reaches the second end 30b. Thereby, each cable-like body 30 suspends the car 6 and the counterweight 7 while being wound around the driving sheave 15, the pair of car suspension cars 9, and the weight suspension car 10.

  The load acting on the first rope stopper 26 is shared and supported by the first car guide rail 2 and the first weight guide rail 4 via the connection support 13. The load acting on the second rope stopper 27, the load acting on the hoisting machine 12, and the own weight of the hoisting machine 12 are transmitted through the machine base 11 to the second car guide rail 3 and the first weight guide rail. 4 and the second weight guide rail 5 are shared and supported.

  Here, the case where there is no connection support body 13 is considered. In the absence of the connecting support 13, the load acting on the first rope stopper 26 is supported by only one first car guide rail 2. Therefore, in this case, the load acting on the first car guide rail 2 is applied to each of the second car guide rail 3, the first weight guide rail 4 and the second weight guide rail 5. There is a possibility that it becomes larger than the load per rail.

  On the other hand, in the present embodiment, the load acting on the first rope stopper 26 is supported not only by the first car guide rail 2 but also by the first weight guide rail 4. The burden on the first car guide rail 2 is smaller than in the case where there is no 13.

  FIG. 4 is a front view showing the connection support 13 of FIG. The load F acting on the first rope stopper 26 is expressed by the following formula (1), where W1 is the weight of the car 6 and W2 is the load weight of the car 6.

  F = (W1 + W2) / 2 (1)

  Of the load F acting on the first rope stopper 26, the burden load F1 of the first car guide rail 2 is expressed by the following equation (2). Furthermore, the load F2 of the first weight guide rail 4 among the loads F acting on the first rope stopper 26 is expressed by the following formula (3).

  F1 = F × L2 / (L1 + L2) (2)

  F2 = F × L1 / (L1 + L2) (3)

  Therefore, the ratio of the respective burdens of the first car guide rail 2 and the second weight guide rail 4 to the load F acting on the first rope stopper 26 can be adjusted by adjusting the distances L1 and L2. is there.

  The third support beam 18 is inclined downward from the other end of the second support beam 17 toward the first weight guide rail 4. Therefore, in a state where the burden load F <b> 2 acts on the first weight guide rail 4, a tensile load acts on the second support beam 17 and a compressive load acts on the third support beam 18. Further, no bending moment acts on each of the second support beam 17 and the third support beam 18. Furthermore, in the present embodiment, the other end of the first support beam 16 is supported by the second support beam 17 and the third support beam 18 that are respectively attached to the first weight guide rail 4. The bending moment acting on the first car guide rail 2 is suppressed.

  Next, the operation will be described. When the hoisting machine 12 is driven and the driving sheave 15 rotates, the cord-like body 30 moves according to the rotation of the driving sheave 15. As a result, the car 6 moves up and down while being guided by the first car guide rail 2 and the second car guide rail 3, and the counterweight 7 is moved to the first weight guide rail 4 and the second weight guide rail. 5 while moving up and down.

  In such an elevator apparatus, the first support beam 16 is mounted on the first beam mounting portion 21 of the first car guide rail 2, and the second beam mounting portion 22 and the first beam mounting portion 22 of the first weight guide rail 4 are connected. The second support beam 17 and the third support beam 18 are respectively attached to the third beam attachment portion 23, and the second support beam 17 is connected to the first support beam 16. Is connected to the second support beam 17 and the first end 30a of the cord-like body 30 is supported by the first support beam 16, so that the load F acting on the first end 30a is Not only the first car guide rail 2 but also the first weight guide rail 4 can be shared and supported. Thereby, a part of the load of the load of the first car guide rail 2 can be transferred to the first weight guide rail 4, and the first car guide rail 2, the second car guide rail 3, and the first car guide rail 2 can be moved. The load burden of the weight guide rail 4 and the second weight guide rail 5 can be made close to each other. Therefore, it is possible to prevent the size of the guide rails 2 to 5 from increasing and the number of rail brackets from increasing, and the installation cost of the guide rails 2 to 5 can be suppressed.

  Further, since the second beam mounting portion 22 and the third beam mounting portion 23 are separated from each other in the vertical direction, the truss structure can be constituted by the second support beam 17 and the third support beam 18. The connection support 13 can be strengthened.

  Moreover, since the position of the 1st beam attachment part 21 exists in the same height as the position of the 2nd beam attachment part 22, each of the 1st support beam 16 and the 2nd support beam 17 is arrange | positioned horizontally. Thus, the installation work of the first support beam 16 and the second support beam 17 can be facilitated.

  Further, the first support beam 16 is disposed in a space between the first car side surface 6 c of the car 6 and the wall surface of the hoistway 1 when viewed from above, and is disposed outside the area of the car 6. Therefore, the car 6 can be moved to a position where the position of the upper end of the car 6 is higher than the position of the first support beam 16. Thereby, the moving range to the up-down direction of the cage | basket | car 6 can be expanded.

  Further, the second support beam 17 and the third support beam 18 are arranged in a space between the car back surface 6b of the car 6 and the wall surface of the hoistway 1 when viewed from above, and are out of the area of the car 6. Therefore, the range of movement of the car 6 in the vertical direction can be expanded. Further, since the bending moment does not act on the second support beam 17 and the third support beam 18 constituting the truss structure, the second support beam is considered in consideration of only buckling due to compressive load and fracture due to tensile load. The strength of each of the 17 and the third support beam 18 may be designed, and the second support beam 17 and the third support beam 18 can be thinned. Thereby, even if it arrange | positions the 2nd support beam 17 and the 3rd support beam 18 in the car back surface 6b side, the expansion of the distance between the car back surface 6b and the wall surface of the hoistway 1 can be suppressed. Therefore, expansion of the depth dimension of the hoistway 1 can be suppressed, and space saving of the hoistway 1 can be achieved.

  In the above example, one end portion of the third support beam 18 is attached to the third beam attachment portion 23 of the first weight guide rail 4 via the attachment member 24. However, the present invention is not limited to this. Alternatively, one end of the third support beam 18 may be directly attached to the third beam attachment portion 23 by, for example, a bolt and a rail clip.

  In the above example, the position of the second beam mounting portion 22 is at the same height as the position of the first beam mounting portion 21, but the position of the third beam mounting portion 23 is set to the first beam mounting portion 21. You may make it the same height as the position of 21. In this case, the third support beam 18 is disposed horizontally, and the second support beam 17 is inclined with respect to the horizontal plane.

Embodiment 2. FIG.
In the first embodiment, the third beam mounting portion 23 is positioned below the second beam mounting portion 22, but the position of the third beam mounting portion 23 is the same as the position of the second beam mounting portion 22. You may make it upward.

  That is, FIG. 5 is a front view showing the connection support 13 of the elevator apparatus according to Embodiment 2 of the present invention. The third beam mounting portion 23 is located above the second beam mounting portion 22. One end of the third support beam 18 is attached to the third beam attachment portion 23 via an attachment member 24. Similar to the first embodiment, the second support beam 17 is attached to the second beam attachment portion 22 by bolts and rail clips. The other end of the third support beam 18 is connected to the other end of the second support beam 17 as in the first embodiment. Accordingly, the third support beam 18 is inclined with respect to the horizontal plane and the second support beam 17. Further, the third support beam 18 is inclined upward from the other end of the second support beam 17 toward the first weight guide rail 4. The third support beam 18 and the second support beam 17 constitute a truss structure in a state of being attached to the first weight guide rail 4.

  Therefore, in a state where the burden load F2 of the first weight guide rail 4 is applied to the first weight guide rail 4, a tensile load is applied to the third support beam 18 and the second support beam 17 is applied. A compressive load is applied. Further, no bending moment acts on each of the second support beam 17 and the third support beam 18.

  The connection support 13 supports an electronic device 41 that is a device in the hoistway that is lighter than the weight of the car 6, the counterweight 7, and the hoisting machine 12. In this example, the electronic device 41 is supported by the connection support body 13 with the housing of the electronic device 41 attached between the second support beam 17 and the third support beam 18. Other configurations are the same as those in the first embodiment.

  In such an elevator apparatus, the position of the second beam mounting portion 22 is at the same height as the position of the first beam mounting portion 21, and the third beam mounting portion 23 is higher than the second beam mounting portion 22. Since it is located above, the length of the second support beam 17 on which the compressive load acts can be made shorter than the length of the third support beam 18. Thereby, it is possible to make it difficult for buckling due to a compressive load to occur in the connection support 13.

  In the above example, the position of the second beam mounting portion 22 is at the same height as the position of the first beam mounting portion 21, but the position of the third beam mounting portion 23 is set to the first beam mounting portion. You may make it the same height as the position of 21. In this case, the third support beam 18 is disposed horizontally, and the second support beam 17 is inclined with respect to the horizontal plane.

  In the first and second embodiments, the third support beam 18 is connected to the second support beam 17. However, the third support beam 18 may be connected to the first support beam 16. In this case, the other end of the third support beam 18 is attached to the other end of the first support beam 16 with, for example, a bolt. Even in this case, the load from the first support beam 16 can be transmitted to the first weight guide rail 4 via the second support beam 17 and the third support beam 18, and the first car guide The burden of the load on the rail 2 can be reduced.

Embodiment 3 FIG.
In the first and second embodiments, the position of the first beam mounting portion 21 is at the same height as the position of the second beam mounting portion 22 or the third beam mounting portion 23. You may set the position of the 1st beam attachment part 21 to the same height as the position between this position and the position of the 3rd beam attachment part 23.

  6 is a front view showing the connection support 13 of the elevator apparatus according to Embodiment 3 of the present invention. The third beam mounting portion 23 is located below the second beam mounting portion 22. The position of the first beam mounting part 21 is at the same height as the position between the position of the second beam mounting part 22 and the position of the third beam mounting part 23 in the vertical direction. Thereby, the 1st support beam 16 is arrange | positioned at the same height as the position between the position of the 2nd beam attachment part 22 and the position of the 3rd beam attachment part 23 about an up-down direction.

  One end portion of the second support beam 17 is attached to the second beam attachment portion 22 with a bolt and a rail clip. One end portion of the third support beam 18 is attached to the third beam attachment portion 23 by a bolt and a rail clip.

  A plate-like attachment member 28 is fixed to the other end of the first support beam 16. The attachment member 28 is disposed orthogonal to the longitudinal direction of the first support beam 16. The other end portions of the second support beam 17 and the third support beam 18 are fastened to the attachment member 28 with bolts. That is, each of the second support beam 17 and the third support beam 18 is connected to the first support beam 16 via the attachment member 28.

  Each of the second support beam 17 and the third support beam 18 is inclined with respect to the horizontal plane. The second support beam 17 is inclined upward from the first support beam 16 toward the first weight guide rail 4, and the third support beam 18 is inclined from the first support beam 16 to the first weight guide rail 4. It is inclined downward. Accordingly, a tensile load acts on the second support beam 17 and a compressive load acts on the third support beam 18. A bending moment does not act on each of the second support beam 17 and the third support beam 18.

  The connection support 13 supports an electronic device 41 that is a device in the hoistway that is lighter than the weight of the car 6, the counterweight 7, and the hoisting machine 12. The method of attaching the electronic device 41 to the connection support 13 is the same as in the second embodiment. Other configurations are the same as those in the first embodiment.

  Even in this case, a part of the load of the first car guide rail 2 can be transferred to the first weight guide rail 4, and the size of the guide rails 2 to 5 can be increased or the number of rail brackets can be increased. It is possible to prevent the increase. Thereby, the installation cost of the guide rails 2-5 can be suppressed. Moreover, a truss structure can be comprised by the 2nd support beam 17 and the 3rd support beam 18, and the connection support body 13 can be strengthened.

  In the above example, the second support beam 17 is directly attached to the second beam attachment portion 22. However, the second support beam 17 is attached to the second beam attachment portion 22 in the first or second embodiment. You may attach via the attachment member 24 of this. In the above example, the third support beam 18 is directly attached to the third beam attachment portion 23. However, the third support beam 18 is attached to the third beam attachment portion 23 in the first or second embodiment. You may attach via the attachment member 24 of this.

  In the above example, each of the second support beam 17 and the second support beam 18 is connected to the first support beam 16 via the attachment member 28, but the other end of the third support beam 18. The portion may be connected to the other end of the second support beam 17.
