Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension vehicle mounting device and a suspension vehicle mounting method for mounting a suspension vehicle by diverting or replacing a beam included in an existing elevator device, for example, when repairing an elevator.

  2. Description of the Related Art Conventionally, there is an elevator apparatus having a configuration in which a beam is attached to an upper or lower part of a car so that a longitudinal direction thereof is parallel to a back or side face of the car and an end of a rope is fixed to the beam. As a method of attaching the beam to the lower part of the car, there is a type in which the tip of the beam is projected from the lower part of the car toward the wall of the hoistway, and the end of the rope is fixed to the tip of the projected beam. However, in such an elevator apparatus, when projecting the tip of the beam from the car, the layout is restricted by a gap between the car and the hoistway, a guide rail provided on the hoistway, and the like, so that the longitudinal length of the beam is reduced. The direction may not be arranged parallel to the back or side of the car.

  When such an elevator device is modified to an elevator device configured to attach a suspension wheel to a beam provided on a car, the suspension vehicle is attached to the beam at an inappropriate angle. Therefore, the technique described in Patent Literature 1 uses a plurality of mounting plates on the suspension vehicle so that the mounting angle of the suspension vehicle can be changed when the suspension vehicle is mounted on a beam that is not arranged parallel to the back or side surface of the car. Mounting holes are provided.

  However, in the technique described in Patent Document 1, since the suspension vehicle and the support member of the suspension vehicle and the mounting plate to the mounting beam are integrated, when the mounting plate is replaced for further repair, the suspension vehicle is not used. In addition, it is necessary to replace the support member of the suspension car together with the mounting plate. In addition, the mounting plate described in Patent Document 1 has a structure in which a mounting surface provided with a plurality of mounting holes protrudes largely in the horizontal direction with respect to a support member of the suspension vehicle and is fastened from the upper side. Unless the beam has a mounting surface, it cannot be mounted.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and does not require replacement of the suspension vehicle and the support member of the suspension vehicle even when the mounting plate is replaced. It is another object of the present invention to provide an elevator hoisting device that can be attached to a beam having no attachment surface at the top.

And, on one end side in the longitudinal direction of the beam 50, three through holes for fastening the connecting body 10 are provided in each of two side walls forming a U-shaped cross section. In this manner, the suspension device is configured, and the support plate 90 that supports the suspension vehicle 80 is attached by abutting the pair of support plate attachment surfaces 11 of the connector 10, and the pair of beam attachment surfaces 12 of the connector 10 are By fixing the suspension 80 to the beam 50 via the connecting body 10, the suspension 80 is fixed to the beam 50 via the connecting body 10, and the rotation axis L <b> 1 of the suspension 80 and the longitudinal center line L <b> 2 of the beam 50. Are fixed at a predetermined angle.

  Next, with reference to FIGS. 2 to 6, a description will be given of a case where the hydraulic elevator apparatus 100 is modified into the rope elevator apparatus 200 using the suspension device according to the first embodiment.

  FIG. 2 is a schematic view of the hydraulic elevator apparatus before the repair as viewed from the side, and FIG. 3 is a cross-sectional view along the line III-III in FIG. As shown in FIGS. 2 and 3, in the hydraulic elevator apparatus 100, a car 20, a guide rail 40 that guides the car 20 to go up and down in a hoistway 30, and a sheave 60 is fixed to a tip end. The hydraulic jack 70 includes a hydraulic jack 70, a beam 50 attached to the bottom surface of the car 20, one end side fixed to the beam 50, and the other end side including a rope 61 wound around a sheave 60. The car 20 is moved up and down by being moved up and down. 2 and 3, the car 20 has a side facing the landing 21 as a front side and an opposite side as a back side.

  When a rope 61 for raising and lowering the car 20 and a beam 50 for attaching the suspension vehicle 80 are provided below the car 20, the longitudinal center line L2 of the beam 50 is It is desirable to arrange the car 20 so that it passes through the center of gravity and is parallel to the side surface or the back surface of the car 20.

  However, in the elevator apparatus having the car 20 and the hoistway 30 as shown in FIGS. 2 and 3, since the distance between the rear surface of the car 20 and the inner wall of the hoistway 30 is narrow, the longitudinal direction of the beam 50 In a case where the end of the beam 50 is made to protrude to the rear side of the car 20 when arranged in parallel with the side surface of the elevator 20, the beam 50 interferes with the inner wall of the hoistway 30.

  On the other hand, since there is room in the space between the side surface of the car 20 and the inner wall of the hoistway 30, the end of the beam 50 can be protruded toward the side surface of the car 20. However, when the longitudinal direction of the beam 50 is arranged in parallel with the back surface of the car 20 and the center line L2 in the longitudinal direction of the beam 50 is arranged to pass through the center of gravity G of the car 20, the end of the beam 50 becomes When projecting to the side of the car 20, it interferes with the guide rail 40 provided on the hoistway 30. Therefore, in this hydraulic elevator apparatus 100, as shown in FIG. 3, the center line L2 in the longitudinal direction of the beam 50 is arranged so as to form an angle α with the back surface of the car 20, so that the guide rail 40 And avoid interference.

  FIG. 4 shows a drive unit of the hydraulic elevator apparatus 100 shown in FIG. 3, in which the sheave 60 and the hydraulic jack 70 are removed, the rope 61 is removed from the beam 50, and then the connecting body 10 is attached to the beam 50. It shows the state where it was turned on. As shown in FIG. 4, the connecting body 10 is formed to be a parallelogram in a top view, and is formed such that the support plate mounting surface 11 is parallel to the side surface of the car 20 when mounted on the beam 50. Have been.

  FIG. 5 shows a state where the support plate 90 of the suspension vehicle 80 is fixed to the support plate mounting surface 11 of the connecting body 10 shown in FIG. Since the support plate mounting surface 11 of the connecting body 10 is parallel to the side surface of the car 20, the rotation axis L 1 of the hanging vehicle 80 mounted on the support plate mounting surface 11 via the support plate 90 is connected to the rear surface of the car 20. And become parallel. If the hoist 80 is attached to the beam 50 in such a posture, the hoist 80 does not interfere with the inner wall of the hoistway 30 or the guide rail 40.

  As described above, if the connecting body 10 in the hoisting device of the present invention is used, the hoisting wheel 80 is attached to the beam 50 via the connecting body 10 without rotating the rotating shaft L1 of the hoisting wheel 80 without adjusting the direction. The axis L1 can be parallel to the back of the car 20. Further, since the connecting body 10 is fixed to the inner wall of the beam 50, the connecting body 10 can be attached even to a beam 50 having no mounting surface on the upper portion, and the connecting body 10 does not protrude around the beam 50. Furthermore, even if a situation occurs in which the direction of the rotation axis L1 of the hoist 80 is changed, the support plate 90 of the hoist 80 and the connecting body 10 are separate bodies. Frequently, it is not necessary to replace the hanging wheel 80 and the supporting plate 90 of the hanging wheel.

  FIG. 6 is a schematic side view of the rope type elevator device 200 after the hydraulic elevator device 100 of FIG. 2 has been repaired. As shown in FIG. 6, in the rope type elevator apparatus 200, a drive unit support beam 52 is installed above the hoistway 30, and the drive unit of the car 20 is newly arranged. Uses the car 20 and the beam 50 in the hydraulic elevator apparatus 100.

  A sheave 82 and a thruster 83 of a hoist are installed on a drive part support beam 52 provided at an upper portion of the hoistway 30, and one end of a rope 81 is fixed. On the other end of the rope 81, a weight 84 is suspended, and further, the other end of the rope 81 is wound around the thruster wheel 83 and the sheave 82, and is wound around the hanging wheel 80 of the car 20, It is fixed to the drive section support beam 52. Then, the car 20 of the rope type elevator apparatus 200 is suspended by a rope 81 driven by a sheave 82 of a hoist and moves up and down. The configuration of the drive unit of the rope type elevator apparatus 200 is an example, and the arrangement of the sheave 82, the thruster wheel 83, the weight 84, and the rope 81 of the hoisting machine is not limited to this.

  Next, a procedure for repairing the hydraulic elevator device 100 shown in FIG. 2 to the rope type elevator device 200 shown in FIG. 6 will be described. Here, the repair procedure of the control system and the power supply system is omitted.

  First, the connecting body 10 to be attached to the beam 50 of the hydraulic elevator apparatus 100 to be repaired is manufactured. In manufacturing the connector 10, the beam mounting surface 12 and the support plate mounting surface 11 of the connector 10 are formed based on the angle formed between the longitudinal center line L <b> 2 of the beam 50 and the back or side surface of the car 20. Determine the angle.

  As shown in FIG. 3, when the center line L2 in the longitudinal direction of the beam 50 forms an angle α with the back surface of the car 20, the rotation axis L1 of the pulling sheave 80 is arranged parallel to the back surface of the car 20. In order to do so, as shown in FIG. 5, it is sufficient to mount so that the rotation axis L1 of the hanging wheel 80 and the longitudinal center line L2 of the beam 50 form an angle α. At this time, since the surface of the support plate 90 that supports the suspension vehicle 80 and is attached to the connecting body 10 is perpendicular to the rotation axis L1, the support plate mounting surface 11 of the connecting body 10 is also perpendicular to the rotation axis L1. . Further, since the rotation axis L1 is parallel to the rear surface of the car 20, the support plate mounting surface 11 of the connector 10 is parallel to the side surface of the car 20, as shown in FIG.

  As shown in FIG. 4, the beam mounting surface 12 adjacent to the support plate mounting surface 11 of the connecting body 10 is parallel to the side wall of the beam 50, and thus is parallel to the longitudinal center line L2 of the beam 50. Therefore, the angle β between the support plate mounting surface 11 and the beam mounting surface 12 in the connecting body 10 shown in FIG. 4 is 90 ° −α. In this way, the angle between the pair of adjacent beam mounting surfaces 12 and the support plate mounting surface 11 of the connector 10 is determined. Further, the dimensions of the surface of the beam 50 to which the connecting body 10 is fixed are measured, and the presence or absence of existing holes in the beam 50 is checked, and the number and position of the screw holes provided on each surface of the connecting body 10 are determined. Then, the connected body 10 is manufactured.

In the repair work, first, the car 20 of the hydraulic elevator apparatus 100 is lowered to the lowermost end and stopped.
Next, the rope 61, the sheave 60, and the hydraulic jack 70 are removed.
Next, a drive part support beam 52 that supports a hoist and the like is attached to the upper part of the hoistway 30. If an existing beam or the like exists in the hoistway 30, this operation is omitted.
Next, the hoisting machine, the sheave 82 and the thruster wheel 83 are installed on the attached driving part support beam 52.
Next, the beam 50 is removed, and a mounting hole for mounting the connecting body 10 is formed. At this time, if an existing hole provided in the beam 50 can be used, this operation is omitted.
Next, the beam 50 is returned to the original position.
Next, the beam mounting surface 12 of the connecting body 10 is brought into contact with the inside of the beam 50, the mounting hole provided in the beam 50 and the screw hole of the beam mounting surface 12 are aligned, and a fastening member is used. The connecting body 10 is fixed to the beam 50.
Next, the support plate 90 of the suspension vehicle 80 is brought into contact with the support plate mounting surface 11 of the connector 10, the mounting holes of the support plate 90 and the screw holes of the support plate mounting surface 11 are aligned, and a fastening member is used. Then, the support plate 90 is fixed to the connecting body 10.
Next, the rope 81 is wound around the hanging wheel 80, and one end side of the rope 81 is returned to the upper drive support beam 52 and fixed.
Next, the other end of the rope 81 is wrapped around the sheave 82 and the solace wheel 83.
Next, a weight 84 is suspended from the other end of the rope 81 via a suspension vehicle or the like, and the other end of the rope 81 is fixed to the drive unit support beam 52.
Thus, the work of repairing the hydraulic elevator device 100 to the rope type elevator device 200 is completed.

  According to such a method of repairing an elevator apparatus, the use of the connecting body 10 allows the hanging wheel 80 to be attached to the existing beam 50 attached to the existing car 20 without adjusting the attachment angle. In addition, the period of the renovation work can be shortened, and the renovation cost can be reduced. Even if the existing beam 50 is not used and replaced with a newly manufactured beam, the mounting angle can be adjusted by previously drilling a mounting hole for attaching the connecting body 10 to the new beam. The same effect can be obtained because the hanging wheel 80 can be attached without performing.

  In the first embodiment, the connecting body 10 is a hexahedron having a parallelogram-shaped cross section in the horizontal direction, but is not limited thereto. For example, a polyhedron having a hexagonal cross section as shown in FIGS. 7 and 8 may be used, or the support plate 90 may be formed in a circular column shape. 6 and 7 includes a pair of first support plate mounting surfaces 11a facing each other and a pair of second support plate mounting surfaces 11b facing each other. Then, as shown in FIG. 7, whether the support plate 90 of the hanging vehicle 80 is attached to the pair of first support plate attachment surfaces 11a or is attached to the pair of second support plate attachment surfaces 11b as shown in FIG. Thereby, the mounting angle of the support plate 90 with respect to the connecting body 10a can be changed. At this time, the support plate 90 of the suspension vehicle 80 is attached to the first support plate of the connecting body 10a by using one of the three through holes provided in two rows of three through holes in the vertical direction. Surface or three screw holes provided on the second support plate mounting surface. According to such a connecting body 10a, it is possible to change the mounting angle of the hanging wheel 80 with respect to the beam 50 without removing the connecting body 10a from the beam 50. In the first embodiment, the top surface and the bottom surface of the connecting body are flat, but the present invention is not limited to this. For example, the top surface or the bottom surface may be a curved surface or a pyramid shape.
