Abstract

(57) [Summary] [Purpose] To protect the anti-lifting side of the guide rail from damage caused by dragging, and to move it smoothly and safely. [Structure] The other end of the guide rail 2 whose one end is suspended from the upper part of the hoistway 3 is attached to a bottom plate 5 that holds a cross section of the guide rail 2, and a bottom grip member 6a that holds a part of the bottom surface of the guide rail 2. , mounted on a support member 8 having neck gripping members 6b and 6c that hold the neck of the guide rail 2,
A caster 7 is attached to the bottom of this support member 8, and the other end of the guide rail 2 is moved and drawn into the hoistway 3 by the caster 7, and then the guide rail 2 is fixed at a predetermined position.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a lifting aid for an elevator guide rail.

0002

[Conventional technology]

Conventional elevator guide rail retraction is disclosed in Japanese Patent Application Laid-Open No. 141282/1982. An elevator guide rail placed horizontally in an elevator landing, as described in While lifting one end from the top of the hoistway, pull it into the hoistway and load it one by one. I was trying to raise it up and install a guide rail.

0003

[Problem that the idea aims to solve]

Conventional elevator guide rail retraction was done as described above, Lift up one end of the guide rail placed in the elevator landing and pull it into the hoistway. When moving, the other end of the guide rail moves while dragging on the floor of the elevator landing. This may damage the end of the guide rail or cause the guide rail to be close to vertical. When this happens, the amount of movement of the other end dragging on the floor becomes long and rapid. It is also very dangerous.

0004 The purpose of this invention is that when one end of the guide rail is lifted, the other end Protects against damage and allows for smooth and safe horizontal movement of the other end To provide a lifting auxiliary device for elevator guide rails that can be used to It is in.

[0005]

[Means to solve the problem]

In order to achieve the above object, the present invention provides a support member that supports the other end of the guide rail. and a caster attached to the support member.

[0006]

[Effect] The lifting auxiliary device for elevator guide rails according to the present invention is constructed as described above. Therefore, when pulling the guide rail from the elevator landing to the hoistway, the guide Slide the guide rail with the other end of the rail held by a support member with casters. When one end is lifted, the other end follows the caster and is damaged on the floor. You can easily control the amount of movement at the other end and work safely. Wear.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. Figures 2 and 3 show an elevator guide rail hoist according to an embodiment of the present invention. FIG. 2 is a perspective view and a plan view of the elevator assisting device, and shows a cross section of the elevator guide rail. a bottom plate 5 that stands upright with the bottom plate 5 and supports the bottom of the guide rail 2; The holding member 6a is formed upright on the bottom 5 and supports the neck of the guide rail 2. The neck gripping members 6b and 6c, which are erected at positions that do not come into close contact with the bottom gripping members, are used to support the It constitutes a holding member 8, and a rotatable caster 7 is provided at the bottom of this supporting member 8. Ru.

[0008] A side view showing the usage status of the lifting aid for the guide rail of this elevator. It is shown in FIG. Pull guide rail 2 from elevator landing 1 to hoistway 3 When lifting, connect the lower end of the wire rope 4 suspended from the top of the hoistway 3 to the guide rail. Tie one end of the guide rail 2 together, and attach the bottom and neck of the other end of the guide rail 2 to the guide rail suspension. be held by the bottom gripping member 6a, neck gripping members 6b, 6c of the lifting assisting device. Attach it in such a way that the other end is lifted off the floor of landing hall 1 using casters 7. . In this state, gradually lift the wire rope 4 tied to one end of the guide rail 2. As you go up, the other end of the guide rail 2 is in contact with the floor at the caster 7. There is no damage to the end of the guide rail 2, and there is no intermittent movement. It moves smoothly following the lifting of the rope 4, and its movement is easily controlled. Therefore, the work can be carried out safely and lifted into the hoistway 3.

[0009]

[Effect of the idea]

As explained above, according to the present invention, the other end of the guide rail is raised by a caster. Since the structure is configured to move by dragging the guide rail, it is possible to move by dragging the end of the guide rail. There was no damage to the guide rail, and as the guide rail was lifted up, other guide rails were removed. The end can be moved smoothly along the landing surface, and the guide rail The other end can be lifted and carried safely without moving all at once. Ru.
