Detailed Description
An elevator according to an embodiment will be described below with reference to fig. 1 to 9. In the drawings, common members are denoted by the same reference numerals.
1. Structure of elevator
First, the structure of an elevator according to an embodiment of the present invention (hereinafter referred to as "this example") will be described with reference to fig. 1.
Fig. 1 is a schematic configuration diagram showing a structural example of an elevator of this example.
As shown in fig. 1, the elevator 1 of the present example performs a lifting operation in an elevator hoistway 110 formed in a building structure. The elevator 1 comprises a car 120 loaded with people and goods, ropes 130, a counterweight 140 and a hoisting machine 100. The elevator shaft 110 is formed in a building structure, and a machine room 160 is provided on top of the elevator shaft.
The hoisting machine 100 is disposed in the machine room 160, and the car 120 is lifted and lowered by winding the rope 130. Further, a deflector pulley (deflector wire) 150 is provided near the hoisting machine 100 to mount the cable 130.
The counterweight 140 is set to have substantially the same mass as the car 120 is empty. Therefore, when no load or no load is placed in the car 120, the tension ratio of the rope 130 on the car 120 side to the counterweight 140 side is 1. This can suppress the output of the hoisting machine 100 at the time of no load to be low.
The car 120 is coupled to a counterweight 140 via a rope 130, and moves up and down in the hoistway 110.
[ Car ]
Next, the structure of the car 120 will be described with reference to fig. 2 and 3.
Fig. 2 is an external perspective view of the car 120. Fig. 3 is a perspective view showing a part of an upper frame and a vertical frame of the car 120.
As shown in fig. 2, the car 120 has a car room 121, a car frame 122, and a door unit not shown. The car chamber 121 is formed in a hollow substantially rectangular parallelepiped shape. One surface of the car chamber 121 is provided with an entrance as an opening. People and goods enter and exit the inner space of the car chamber 121 from the entrance and exit. A door unit is provided at an entrance of the car room 121. The door unit is configured to be capable of opening and closing an entrance of the car chamber 121.
The car room 121 includes a car floor 125, 4 side plates 126A to 126D, and a car roof 127. The car floor 125 is formed in a substantially rectangular shape. 4 side plates 126A to 126D are disposed around the car floor 125. The ceiling plate 127 is opposed to the car floor 125 in the up-down direction. 4 side plates 126A to 126D are disposed around the ceiling plate 127.
The side plate 126A is formed with the above-described inlet and outlet. The side plate 126A is opposite to the side plate 126B. Further, the side plate 126C is opposite to the side plate 126D. Hereinafter, the direction in which the side plate 126A and the side plate 126B face each other is referred to as the front-rear direction, and the direction in which the side plate 126C and the side plate 126D face each other is referred to as the left-right direction.
The car frame 122 is formed in a rectangular frame shape surrounding the car floor 125, the side plates 126C and 126D, and the car ceiling 127. The car frame 122 has a lower frame 21 supporting the car floor 125, vertical frames 22A, 22B facing the side plates 126C, 126D, respectively, and an upper frame 23 facing the car ceiling 127.
The vertical frames 22A and 22B extend in the up-down direction. The cross-sectional shape orthogonal to the vertical direction of the vertical frames 22A, 22B is substantially C-shaped. The vertical frames 22A and 22B are opposed to 2 guide rails 170 (1 is omitted in fig. 2) provided in the elevator shaft 110 (see fig. 1). The 2 guide rails 170 extend in the up-down direction. The 2 guide rails 170 guide the car 2 in the up-down direction (lifting direction).
The upper portions of the vertical frames 22A, 22B are connected to the upper frame 23 using a connecting member 37 described later. Further, 4 raised members 31 are connected to the longitudinal frames 22A, 22B and the upper frame 23 using screws.
The upper frame 23 extends in the left-right direction. The cross-sectional shape orthogonal to the left-right direction of the upper frame 23 is substantially C-shaped. 2 sliders 25 (1 omitted from fig. 2) are fixed to the upper frame 23. The 2 sliders 25 are disposed at both ends in the longitudinal direction of the upper frame 23. The 2 sliders 25 slidably engage with the 2 guide rails 170, respectively. Thereby, the car 120 is guided by the 2 guide rails 170 to move up and down in the hoistway 110 (see fig. 1).
As shown in fig. 3, the vertical frames 22A, 22B have a base sheet 221 and side sheets 222, 223 continuous with the base sheet 221. The substrate 221 is formed in a rectangular shape long in the up-down direction. The plane of the substrate 221 is orthogonal to the left-right direction. One plane of the base 221 is opposite to the side plate 126C (126D) of the car 121. The upper portion of the substrate 221 is provided with 2 through holes 221a for connection members. The connection member screws (bolts) 55 pass through the 2 connection member through holes 221a (see fig. 9).
The side panels 222, 223 stand up substantially perpendicularly from the long sides of the base 221. The side pieces 222 and 223 are formed in a rectangular shape long in the up-down direction. The planes of the side panels 222, 223 are orthogonal to the front-rear direction. The side panels 222, 223 are opposed in the front-rear direction. The upper portions of the side panels 222 and 223 are respectively provided with 2 through holes 224 for the raised members. The vertical frame screws (bolts) 51 pass through the 2 through holes 224 (see fig. 6) for the height-increasing member.
The upper frame 23 has a base sheet 231 and side sheets 232, 233 continuous with the base sheet 231. The substrate 231 is formed in a rectangular shape long in the left-right direction. The plane of the substrate 231 is orthogonal to the up-down direction. One plane (lower surface) of the base 231 is opposite to the ceiling 127 of the car 121. Two ends of the base 231 in the lateral direction are provided with 2 through holes 231a for connecting members. The connection member screws (bolts) 55 pass through the 2 connection member through holes 231a (see fig. 9).
The side pieces 232, 233 stand up substantially perpendicularly from the long sides of the base 231. The side panels 232, 233 are formed in a rectangular shape long in the left-right direction. The planes of the side panels 232, 233 are orthogonal to the front-rear direction. The side panels 232, 233 are opposed in the front-rear direction. Two through holes 234 for 2 height-increasing members are provided at both ends of the side pieces 232, 233 in the lateral direction. The upper frame screws (bolts) 53 pass through 2 through holes 234 for the height-increasing member (see fig. 6).
[ heightening Member ]
Next, the structure of the elevation member 31 will be described with reference to fig. 4 and 5.
Fig. 4 is a perspective view of the raised member 31 from the outer surface side. Fig. 5 is a perspective view of the raised member 31 from the inner surface side.
As shown in fig. 4 and 5, the height-increasing member 31 is constituted by a plate body having a substantially L-shape in plan view. The elevation member 31 has a vertical frame connecting portion 32 connected to the vertical frame 22A (22B) and an upper frame connecting portion 33 connected to the upper frame 23. The vertical frame connecting portion 32 is formed in a rectangular shape extending in the up-down direction. The vertical frame connecting portion 32 is provided with a vertical frame screw through hole 32a through which the vertical frame screw 51 is passed. The screw through holes 32a for the vertical frames are formed in a vertically elongated shape extending in the vertical direction. This makes it possible to easily change the connection position of the elevation member 31 in the up-down direction.
The upper frame connecting portion 33 is continuous with the upper side of the vertical frame connecting portion 32. The upper frame connecting portion 33 has a screw penetrating piece 34 formed in a rectangular shape extending in the left-right direction and a support piece 35 continuous with the screw penetrating piece. The screw penetration piece 34 abuts against the side piece 232 (233) of the upper frame 23. The screw through-piece 34 has 2 upper frame screw through-holes 34a and suspension holes 34b.
The 2 upper frame screw through holes 34a are arranged at appropriate intervals in the left-right direction. The upper frame screws 53 pass through the 2 upper frame screw through holes 34a. The hanging hole 34b is disposed at a corner of the upper portion of the screw penetrating piece 34 on the side of the vertical frame connecting portion 32. The suspension hole 34b is used when the elevation member 31 is suspended.
The support piece 35 is formed by bending processing. The support piece 35 protrudes substantially perpendicularly from the lower side of the screw penetration piece 34. The support piece 35 is abutted against one plane (lower surface) of the base 231 of the upper frame 23. Thereby, the support piece 35 supports the lower portion of the upper frame 23. As a result, the load of the upper frame 23 can be prevented from being concentrated on the upper frame screws 53.
[ heightening operation of upper frame ]
Next, the raising operation of the upper frame 23 will be described with reference to fig. 6 to 9.
Fig. 6 is a perspective view showing a state in which the elevation member 31 is connected to the car frame 122. Fig. 7 is a perspective view showing a state before the upper frame 23 is raised. Fig. 8 is a perspective view showing a state in which the upper frame 23 is raised. Fig. 9 is a perspective view showing a state in which the upper frame 23 and the vertical frame 22A are connected by the connecting member 37.
When the car 120 of the elevator 1 is mounted in a building structure, first, the vertical frames 22A and 22B of the car frame 122 are positioned on the guide rail 170. Next, the upper frame 23 and the lower frame 21 are connected to the vertical frames 22A, 22B. In the case of connecting the upper frame 23 to the vertical frame 22A (22B), 4 raised members 31 are used.
As shown in fig. 6, in the operation of connecting the upper frame 23 and the vertical frame 22A (22B), the 2 vertical frame screws (bolts) 51 are inserted through the vertical frame screw insertion holes 32A of the height-increasing member 31 and the 2 height-increasing member insertion holes 224 of the vertical frame 22A (22B), and the nuts 52 are screwed together. Thereby, the elevation member 31 is connected to the vertical frame 22A (22B). At this time, the upper vertical frame screw 51 contacts the upper end of the vertical frame screw through hole 32a. The lower vertical frame screw 51 is located in the middle of the vertical frame screw through hole 32a.
Further, 2 upper frame screws (nuts) 53 are passed through the 2 upper frame screw through holes 234 of the upper frame 23 and the 2 upper frame screw through holes 34a of the upper frame 31, and nuts 54 are screwed. Thereby, the elevation member 31 is connected to the upper frame 23. Then, the upper frame 23 is positioned at the connection position with respect to the vertical frames 22A, 22B.
When the upper frame 23 and the vertical frame 22A (22B) are connected by the raised member 31, the vibration-proof member 41 provided on the side surface of the ceiling 127 is brought into contact with the vertical frame connecting portion 32 of the raised member 31 via the vibration-proof rubber 42. Thereby, vibration of the car 121 can be suppressed. The vertical frame connecting portion 32 has a length in the up-down direction set to be at least a length opposite to the vibration isolation member 41 (vibration isolation rubber 42).
Next, as shown in fig. 7, the slider 25 is fixed to the upper frame 23, and the slider 25 is slidably engaged with the guide rail 170. At this time, a screw (nut) 55 for a connecting member is used as a screw for fixing the slider 25. That is, 2 screws (nuts) 55 for connecting members are passed through the slider 25, the through holes for connecting members 37, and the 2 through holes 231a for connecting members of the upper frame 23, and the nuts 56 are screwed.
After the slider 25 is fixed to the upper frame 23, the ceiling 127 of the car room 121 is disposed and suspended in the car frame 122. Next, the lower frame 21 and the side plates 126C and 126D are disposed in the car frame 122, and the 4 side plates 126A to 126D are connected to the car floor 125. At this time, the car floor 125 is supported by the lower frame 21 of the car frame 122.
When the 4 side plates 126A to 126D are connected (assembled), the side plates 126A to 126D may interfere with the ceiling plate 127, and the appearance of the ceiling plate 127 may be impaired. Therefore, the suspended ceiling plate 127 is lifted to a position where it does not interfere with the side plates 126A to 126D. At this time, the upper frame 23 of the car frame 122 interferes with the car ceiling 127, and thus the upper frame 23 is raised.
In the raising operation, when the car top plate 127 is raised, the upper frame 23 is raised to a raised position where interference with the car top plate 127 does not occur. In the raising operation, the fastening of the screws (bolts) 51 and nuts 52 for the 2 vertical frames is first loosened. Thereby, the elevation member 31 and the upper frame 23 connected to the elevation member 31 can be moved upward.
Thereafter, as shown in fig. 8, the elevation member 31 and the upper frame 23 are raised until the lower vertical frame screw 51 contacts the lower end of the vertical frame screw through hole 32a. Thereby, the upper frame 23 is arranged to the raised position. Next, the vertical frame connecting portion 32 of the heightened member 31 and the vertical frame 22A (22B) are fastened by using 2 vertical frame screws (bolts) 51 and nuts 52. Thereby, the raising operation of the upper frame 23 ends.
After 4 side plates 126A to 126D are assembled in the car frame 122, the 4 side plates 126A to 126D are connected to a car ceiling 127. At this time, the ceiling plate 127 is lowered. Next, the fastening of the 2 screws (bolts) 51 for the vertical frames and the nuts 52 is loosened. Then, the raising member 31 and the upper frame 23 are lowered until the upper vertical frame screw 51 contacts the upper end of the vertical frame screw through hole 32a. Thereby, the upper frame 23 is configured to the connection position.
Next, the vertical frame connecting portion 32 of the heightened member 31 and the vertical frame 22A (22B) are fastened by using 2 vertical frame screws (bolts) 51 and nuts 52. Thereby, the upper frame 23 is fixed at the connection position.
Next, as shown in fig. 9, the upper frame 23 and the vertical frame 22A are connected using a connecting member 37. The connecting member 37 improves the connection strength between the upper frame 23 and the vertical frame 22A. In the case where the connection strength of the heightened member 31 is sufficient, the connection member 37 may be omitted. The side surface shape of the connecting member 37 is formed in a substantially L-shape.
As described above, the connecting member 37 has been fixed to the upper frame 23. Thus, the connecting member 37 is fixed to the vertical frame 22A (22B). That is, 2 connecting member screws (nuts) 55 are passed through the connecting member 37 and the 2 connecting member through holes 221a of the vertical frame 22A (22B), and nuts (not shown) are screwed. Thereby, the connecting member 37 is fixed to the vertical frame 22A (22B).
As a result, the car 120 according to the present embodiment includes the heightening member 31, and the heightening member 31 is connected to the vertical frames 22A and 22B and the upper frame 23 by using the vertical frame screws 51 and the upper frame screws 53. The height-increasing member 31 has a vertical frame screw through hole 32a through which the vertical frame screw 51 passes and an upper frame screw through hole 34a through which the upper frame screw 53 passes. Then, the vertical frame screw through hole 32a is formed in a vertically elongated shape extending in the vertical direction. By this, the fastening of the vertical frame screw 51 is released, and the raised member 31 in a state of being connected to the upper frame 23 can be easily moved upward. As a result, the raising operation of the upper frame 23 can be facilitated. Further, the upper frame 23 can be held in the raised position by the raised member 31. Thereby the processing time of the product is reduced,
the raising member 31 has a vertical frame connecting portion 32 connected to the vertical frame 22A (22B) by a vertical frame screw 51, and an upper frame connecting portion 33 connected to the upper frame 23 by an upper frame screw 53. Then, the upper frame connecting portion 33 includes a through piece 34 formed with an upper frame screw through hole 34a, and a support piece 35 continuous with the screw through piece 34 and supporting the lower portion of the upper frame 23. This can prevent the load of the upper frame 23 from being concentrated on the upper frame screws 53.
The screw penetration piece 34 of the upper frame connecting portion 33 abuts against the upper frame 23 in the front-rear direction of the car chamber 121. The front-rear direction of the car chamber 121 is a direction orthogonal to the vertical direction in which the vertical frames 22A and 22B extend and the horizontal direction in which the upper frame 23 extends. Therefore, the upper frame 23 and the vertical frames 22A and 22B are connected by the use of the height-increasing member 31, whereby the upper frame 23 can be positioned in the front-rear direction with respect to the vertical frames 22A and 22B.
In the raising member 31, the vertical frame screw through hole 32a and the upper frame screw through hole 34a have the same direction of penetration. Thus, the worker can perform the operation of screwing the vertical frame screw 51 and the nut 52 and the operation of screwing the upper frame screw 53 and the nut 54 without changing the posture. As a result, workability when the height-increasing member 31 is connected to the vertical frames 22A, 22B and the upper frame 23 is improved.
Further, an anti-vibration rubber 42 (anti-vibration material) is interposed between the damper Gao Goujian and the anti-vibration member 41 of the car chamber 121. Thereby, vibration of the car 121 can be suppressed. Furthermore, after installation of the elevator 1, the elevation member 31 can also be connected to the longitudinal frames 22A, 22B and the upper frame 23. Therefore, unnecessary components after the elevator 1 is mounted can be reduced.
Further, the elevation member 31 has a hole 34b for suspension. Thereby, the elevation member 31 can be easily conveyed to an arbitrary height. In addition, the car frame 122 can be suspended as a whole while being connected to the upper frame 23 and the vertical frames 22A, 22B. As a result, the position of the car frame 122 can be easily adjusted.
The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the gist of the invention described in the patent claims.
In the above embodiment, 2 screws 51 for the vertical frames are used for connecting the height-increasing member 31 to the vertical frames 22A and 22B. However, the connection between the height-increasing member and the vertical frame according to the present invention may be performed by using at least 1 vertical frame screw 51. In the above embodiment, 2 upper frame screws 53 are used for connecting the upper frame 23 to the upper member 31. However, the connection of the heightening member and the upper frame according to the present invention may be performed by using at least 1 upper frame screw 53.
In the present specification, the terms "parallel" and "orthogonal" are used, but these terms are not limited to the strict terms "parallel" and "orthogonal", and may include the terms "parallel" and "orthogonal" and are in a state of "substantially parallel" and "substantially orthogonal" within a range where the functions thereof can be exhibited.
