Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device for elevator guide rails.

[0002]

2. Description of the Related Art A conventional guide rail of an elevator is pulled into the hoistway by, for example, one end of the guide rail of the elevator horizontally placed at the landing of the elevator, as described in Japanese Patent Laid-Open No. 56-141,282. The guide rails were installed by hoisting them from the top of the hoistway and pulling them into the hoistway while stacking them in order.

[0003]

Conventionally, when the elevator guide rail is pulled into the hoistway, the other end of the guide rail is pulled when one end of the guide rail placed horizontally at the elevator hall is lifted and pulled into the hoistway. Had been lifted and moved by an operator so as not to drag on the floor of the elevator hall, but this guide rail was long and heavy, and the operator was very tired. Further, since the guide rail is moved to the vicinity of the hoistway and guided into the hoistway, there is a risk that the worker may fall into the hoistway.

The present invention is intended to solve the above-mentioned conventional problems, and an object thereof is to perform horizontal movement when one end of a guide rail is lifted without the operator lifting the other end. (EN) A lifting device for elevator guide rails that can be smoothly and safely performed.

[0005]

In order to achieve the above-mentioned object, the present invention provides a guide rail for an elevator, in which one end of a guide rail placed at an elevator landing is lifted above a hoistway and pulled into the hoistway. In the lifting device for a vehicle, an auxiliary device including a support member that supports the other end of the guide rail, a caster that guides the support member, and a support body that holds the support member is arranged at the other end of the guide rail. It has been configured.

[0006]

According to the present invention, when the guide rail is pulled into the hoistway from the elevator hall, the other end of the guide rail is
If one end of the guide rail is lifted in a state where the auxiliary device including the support member, the caster, and the support body is arranged, the other end of the guide rail moves following the guide rail by the caster of the auxiliary device, and the worker of the guide rail moves. The guide rail can be moved smoothly without lifting the other end.

Further, the auxiliary device that moves following the movement of the guide rail can be controlled away from the hoistway by the support body that holds the support member, and the work can be performed safely.

[0008]

An embodiment of the present invention will be described below with reference to the drawings.

2 and 3 are a perspective view and a plan view of an auxiliary device that constitutes a lifting device for a guide rail of an elevator according to an embodiment of the present invention, and a bottom plate 5 for receiving a cross section of the guide rail 2 of the elevator. A bottom gripping member 6a which is formed upright on the bottom plate 5 and supports the bottom of the guide rail 2, and a bottom gripping member 6a which is formed upright on the bottom 5 and supports the neck of the guide rail 2 and does not adhere to the bottom gripping member 6a. Neck gripping members 6b and 6c erected at the position,
A support member 8 is composed of a grip transmission portion 6d that is formed obliquely on the bottom plate 5 so as to face the bottom grip member 6a. The support member 8 and a rotatable caster provided at the bottom of the support member 8 are provided. An auxiliary device 10 is formed by 7 and a support body 9 that is connected to the grip transmission portion 6d and holds the support member 8.

FIG. 1 shows a usage state of the lifting device for a guide rail of this elevator. When the guide rail 2 is pulled into the hoistway 3 from the elevator hall 1, the lower end of the winch wire rope 4 suspended from the upper part of the hoistway 3 is tied to one end of the guide rail 2, and the bottom and neck of the other end of the guide rail 2 are connected. Bottom gripping member 6 of the auxiliary device 10
a, the neck gripping members 6b and 6c are mounted so as to be sandwiched between them, and the other end of the guide rail 2 is floated from the floor surface of the landing 1 by the casters 7, and the support 9 is pulled. In this state, when the winch wire rope 4 tied to one end of the guide rail 2 is gradually lifted, the other end of the guide rail 2 is in contact with the floor surface via the casters 7, and therefore, in the hoistway 3 direction. Try to move. Here, by loosening the support 9 connected to the support member 8,
The guide rail 2 moves to an appropriate position.

Further, while lifting the winch wire rope 4, the other end of the guide rail 2 is controlled by the support 9, and the other end of the guide rail 2 is moved on the floor surface of the elevator hall 1 and drawn into the hoistway 3. .. When the guide rail 2 becomes vertical, the support member 8 is disengaged from the other end of the guide rail 2, and the auxiliary device 10 is recovered via the support body 9.

As described above, the guide rail 2 smoothly moves on the floor surface of the landing 1 by lifting the winch wire rope 4 and controlling the support 9. Moreover, since the guide rail 2 can be easily controlled at a position away from the hoistway 3, the guide rail 2 can be safely moved while the work is being carried out safely.
It can be hung inside.

[0013]

As described above, according to the present invention, the other end of the guide rail is moved up by being lifted by the caster of the auxiliary device, so that the operator can support the guide rail without lifting the end of the guide rail. The guide rail can be moved smoothly on the floor of the landing only by controlling the body,
Further, since the work can be performed at a position away from the hoistway, the guide rail can be safely pulled into the hoistway without fatigue.
