Hereinafter, embodiments of the suspension vehicle device of the present invention will be described with reference to the drawings.

Embodiment 1 FIG.
FIG. 1 is a configuration diagram illustrating a suspension vehicle device according to Embodiment 1 of the present invention. As shown in FIG. 1, the suspension vehicle device includes a support plate 90 that supports the suspension vehicle 80, a beam 50, and a connector 10 that connects the support plate 90 to the beam 50. The support plate 90 includes a pair of plate-like members, and supports the suspension wheel 80 so as to be sandwiched between the pair of plate-like members from the direction of the rotation axis L1. Four through holes for fastening the support plate 90 to the coupling body 10 are provided at the ends of the pair of plate-like members constituting the support plate 90, respectively.

The connecting body 10 is a hexahedron, a horizontal cross section parallel to the top surface forms a parallelogram, and adjacent side surfaces are not perpendicular but formed at a predetermined angle. Of the pair of opposing side surfaces of the connecting body 10, one pair of side surfaces is a beam mounting surface 12 that is attached to contact with the beam 50, and each has three screw holes. Yes. The pair of side surfaces of the other set is a support plate mounting surface 11 to which the support plate 90 is abutted and attached, and four screw holes for fixing the support plate 90 are provided in each. .

As shown in FIG. 1, the cross section of the beam 50 in the short direction is formed in a U-shape. Then, on one end side in the longitudinal direction of the beam 50, three through holes for fastening the coupling body 10 are provided in each of two side walls constituting a U-shaped cross section. Thus, the suspension vehicle device is configured, and the support plate 90 that supports the suspension vehicle 80 is attached to the pair of support plate attachment surfaces 11 of the connection body 10 so that the pair of beam attachment surfaces 12 of the connection body 10 are connected to the beam. 50, the suspension wheel 80 is fastened to the beam 50 via the coupling body 10, and the rotation axis L1 of the suspension wheel 80 and the longitudinal center line L2 of the beam 50 are fixed. Are fixed to form a predetermined angle.

Next, with reference to FIGS. 2 to 6, the case where the hydraulic elevator apparatus 100 is modified to the rope type elevator apparatus 200 using the suspension vehicle apparatus according to the first embodiment will be described.

FIG. 2 is a schematic view of the hydraulic elevator device before renovation as seen from the side, and FIG. 3 is a cross-sectional view taken along line III-III in FIG. As shown in FIGS. 2 and 3, the hydraulic elevator apparatus 100 includes a car 20 that moves up and down in the hoistway 30, a guide rail 40 that guides the raising and lowering of the car 20, and a sheave 60 fixed to the tip. The hydraulic jack 70 includes a hydraulic jack 70, a beam 50 attached to the bottom surface of the car 20, and a rope 61 having one end fixed to the beam 50 and the other end wound around a sheave 60. The car 20 is raised and lowered by being raised and lowered. Moreover, in FIG.2 and FIG.3, the cage | basket | car 20 makes the side facing the landing 21 the front, and makes the other side the back.

When the rope 61 for raising and lowering the car 20 and the beam 50 for attaching the suspension car 80 are provided at the lower part of the car 20, in consideration of the balance of the weight applied to the beam 50, the center line L2 in the longitudinal direction of the beam 50 is It is desirable to arrange so that it passes through the center of gravity and is parallel to the side surface or 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, the distance between the rear surface of the car 20 and the inner wall of the hoistway 30 is narrow. When the end of the beam 50 is protruded to the back side of the car 20 when arranged in parallel with the side surface of the car 20, it interferes with the inner wall of the hoistway 30.

On the other hand, since there is a sufficient 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 to the side surface side of the car 20. However, when the longitudinal direction of the beam 50 is arranged parallel to the rear surface of the car 20, if the longitudinal center line L 2 of the beam 50 passes through the center of gravity G of the car 20, the end of the beam 50 is When projecting to the side of the car 20, it interferes with the guide rail 40 provided in the hoistway 30. Therefore, in the hydraulic elevator apparatus 100, as shown in FIG. 3, the guide rail 40 is arranged such that the center line L2 in the longitudinal direction of the beam 50 forms an angle α with respect to the back surface of the car 20. To avoid interference.

FIG. 4 shows the drive unit of the hydraulic elevator apparatus 100 shown in FIG. 3, the sheave 60 and the hydraulic jack 70 are removed, the rope 61 is removed from the beam 50, and then the connector 10 is attached to the beam 50. Shows the state. As shown in FIG. 4, the connecting body 10 is formed in a parallelogram shape when viewed from above, and is formed so that the support plate attachment surface 11 is parallel to the side surface of the car 20 when attached to the beam 50. Has been.

FIG. 5 shows a state in which the support plate 90 of the suspension vehicle 80 is fixed to the support plate attachment surface 11 of the connector 10 shown in FIG. Since the support plate mounting surface 11 of the connector 10 is parallel to the side surface of the car 20, the rotation axis L1 of the suspension wheel 80 attached to the support plate mounting surface 11 via the support plate 90 is the back surface of the car 20. Becomes parallel. If the suspension vehicle 80 is attached to the beam 50 in such a posture, the suspension vehicle 80 does not interfere with the inner wall of the hoistway 30 and the guide rail 40.

As described above, by using the connecting body 10 in the suspension vehicle device of the present invention, the suspension car 80 can be rotated without adjusting the direction of the rotation axis L1 of the suspension car 80 only by attaching the suspension car 80 to the beam 50 via the connecting body 10. 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 if the beam 50 does not have a 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 suspension vehicle 80 is changed, the support plate 90 and the connection body 10 of the suspension vehicle 80 are separate from each other, so if only the connection body 10 is replaced. Well, there is no need to replace the suspension vehicle 80 and the suspension vehicle support plate 90.

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

On the driving unit support beam 52 provided at the upper part of the hoistway 30, a sheave 82 of a hoisting machine and a sorceress wheel 83 are installed, and one end side of the rope 81 is fixed. A weight 84 is suspended from the other end side of the rope 81, and the other end side of the rope 81 is wound around the sorase wheel 83 and the sheave 82, and is wound around the suspension wheel 80 of the car 20, The drive unit support beam 52 is fixed. The car 20 of the rope type elevator apparatus 200 is lifted and lowered by being suspended by a rope 81 driven by a sheave 82 of the hoisting machine. Note that the configuration of the drive unit of the rope type elevator apparatus 200 is an example, and the arrangement of the sheaves 82, the ramp wheel 83, the weights 84, and the ropes 81 of the hoisting machine is not limited thereto.

Next, a procedure for repairing the hydraulic elevator apparatus 100 shown in FIG. 2 to the rope type elevator apparatus 200 shown in FIG. 6 will be described. Here, the refurbishment 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 device 100 to be repaired is manufactured. In manufacturing the connecting body 10, the beam mounting surface 12 and the support plate mounting surface 11 of the connecting body 10 are formed based on the angle formed by the longitudinal center line L 2 of the beam 50 and the back surface or side surface of the car 20. Determine the angle.

As shown in FIG. 3, when the center line L 2 in the longitudinal direction of the beam 50 forms an angle α with respect to the back surface of the car 20, the rotation axis L 1 of the suspension wheel 80 is arranged in parallel with the back surface of the car 20. In order to do this, as shown in FIG. 5, the rotation axis L1 of the suspension wheel 80 and the center line L2 in the longitudinal direction of the beam 50 may be attached so as to form an angle α. At this time, since the surface of the support plate 90 that supports the suspension vehicle 80 that is attached to the coupling body 10 is perpendicular to the rotation axis L1, the support plate attachment surface 11 of the coupling body 10 is also perpendicular to the rotation axis L1. . Since the rotation axis L1 is parallel to the back surface of the car 20, the support plate mounting surface 11 of the connecting body 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 coupling body 10 is parallel to the side wall of the beam 50, and thus is parallel to the longitudinal center line L 2 of the beam 50. Therefore, the angle β formed by the support plate mounting surface 11 and the beam mounting surface 12 in the connector 10 shown in FIG. 4 is 90 ° −α. In this manner, the angle formed by the pair of adjacent beam mounting surfaces 12 and the support plate mounting surface 11 of the coupling body 10 is determined. Furthermore, while measuring the dimension of the surface to which the connection body 10 is fixed in the beam 50, and confirming the presence or absence of the existing hole in the beam 50, the number and position of the screw holes provided in each surface of the connection body 10 are determined. Decide and manufacture the connector 10.

In the renovation work, first, the car 20 of the hydraulic elevator apparatus 100 is lowered to the lowest end and stopped.
Next, the rope 61, the sheave 60, and the hydraulic jack 70 are removed.
Next, the drive unit support beam 52 that supports the hoisting machine or the like is attached to the upper part of the hoistway 30. It should be noted that this operation is omitted when there are existing beams in the hoistway 30.
Next, the hoisting machine, the sheave 82 and the sorceress wheel 83 are installed on the attached drive unit support beam 52.
Next, the beam 50 is removed, and a mounting hole for mounting the connector 10 is drilled. At this time, when the 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 coupling body 10 is brought into contact with the inside of the beam 50, the positions of the mounting holes provided in the beam 50 and the screw holes of the beam mounting surface 12 are aligned, and using a fastening member, 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 positions of the mounting holes of the support plate 90 and the screw holes of the support plate mounting surface 11 are adjusted, and a fastening member is used. Then, the support plate 90 is fixed to the connector 10.
Next, the rope 81 is wound around the suspension wheel 80, and one end side of the rope 81 is returned to and fixed to the upper drive unit support beam 52.
Next, the other end side of the rope 81 is wound around the sheave 82 and the wheel 37.
Next, the weight 84 is suspended from the other end side of the rope 81 via a suspension wheel or the like, and the other end side of the rope 81 is fixed to the drive unit support beam 52.
Thus, the work for repairing the hydraulic elevator device 100 to the rope elevator device 200 is completed.

According to such a modification method of an elevator apparatus, the suspension vehicle 80 can be attached to the existing beam 50 attached to the existing car 20 without adjusting the attachment angle by using the connecting body 10. In addition to shortening the repair work period, the repair cost can be reduced. Even when the existing beam 50 is not diverted and replaced with a newly produced beam, the mounting angle can be adjusted by previously drilling a mounting hole for attaching the connector 10 to the new beam. Since the suspension vehicle 80 can be attached without doing, the same effect can be acquired.

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 arc shape in a cylindrical 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, whether the support plate 90 of the suspension vehicle 80 is attached to the pair of first support plate attachment surfaces 11a as shown in FIG. 7, or is attached to the pair of second support plate attachment surfaces 11b as shown in FIG. Thereby, the attachment angle of the support plate 90 with respect to the coupling 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 coupling body 10a using three through holes in one of six through holes provided in two rows in the vertical direction. It is attached to three screw holes provided on the surface or the second support plate attachment surface. According to such a connection body 10a, the attachment angle of the suspension wheel 80 with respect to the beam 50 can be changed without removing the connection body 10a from the beam 50. Moreover, in Embodiment 1, although the top | upper surface and bottom face of the coupling body were planes, it does not restrict to this. For example, the top surface or the bottom surface may be a curved surface or a pyramid shape.
