Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator rope socket mounting device for mounting a rope socket on a terminal portion of a wire rope.

[0002]

2. Description of the Related Art Generally, in an elevator, a rope socket is integrally provided at a terminal portion of a wire rope for lifting a car or the like, and the thimble rod provided in the car or the like is connected to the rope socket. It is like this.

FIG. 5 is a front view showing a state in which a rope socket of this type is attached to a terminal portion of a wire rope. Conventionally, the rope socket 2 is provided at the end of the wire rope 1 in FIG.
To attach the wire rope, first insert the end portion of the wire rope 1 into the rope socket 2, then unravel the end portion of the wire rope 1 and fold the wires together as a plurality of thin wires. Is formed into a chrysanthemum shape. Next, the operator grips the wire rope 1 and hits the end portion 3 of the rope socket 2 with a hammer or the like (not shown) upward in FIG. 5 to fit the end portion of the wire rope 1 into the rope socket 2. Was there.

After that, the molten alloy is injected into the rope socket 2 through the alloy injection hole 4 and solidified, so that the end portion of the wire rope 1 is fixed in the rope socket 2.
The dimension A between the lower edge portion 5 of the alloy injection hole 4 and the upper edge portion 6 of the rope socket 2 is defined by law.

[0005]

By the way, in the above-mentioned prior art, when the rope socket 2 is attached to the end portion of the wire rope 1, the bent thin wire of the end portion of the rope socket 2 and the wire rope 1 are Since a considerable frictional force acts between them, it is difficult to hit the rope socket 1 with a hammer, which requires a lot of labor and takes time. Further, when the dimension A between the lower edge portion 5 of the alloy injection hole 4 and the upper edge portion 6 of the rope socket 2 is set to a predetermined dimension, the rope socket 2 is slightly moved by the manual work of hitting with the hammer. There is also a problem that it is difficult to do so and it takes a lot of trouble.

The present invention has been made in view of the actual situation in the prior art, and an object thereof is to easily attach a rope socket to a terminal portion of a wire rope without requiring manual work of hitting the rope socket with a hammer or the like. An object is to provide an elevator rope socket mounting device that can be mounted.

[0007]

In order to achieve this object, the present invention relates to the rope socket by inserting each thin wire of the wire rope end into the rope socket in a bent state in a loop shape. In an elevator rope socket mounting device to be mounted on a terminal portion of a wire rope, a support body that supports the rope socket, a gripping body that grips the wire rope, and the wire rope from the rope socket via the gripping body. A pulling means for pulling the gripping body away and a movement restricting means for restricting the movement of the gripping body when the gripping body moves by a predetermined dimension are provided.

[0008]

Since the present invention is configured as described above, the rope socket is supported by the support body and the wire is held by the gripping body in a state in which each thin wire of the wire rope end portion inserted in the rope socket is bent in a loop shape. Grasp the rope,
The wire rope is towed by the towing means in the direction away from the rope socket via the gripping body. And
When the gripping body moves by a predetermined dimension by the operation of the towing means, the movement of the gripping body is restricted by the movement restricting means, so that the end portion of the wire rope is fitted into the rope socket of a predetermined size. As a result, the rope socket can be easily attached to the end portion of the wire rope without requiring manual work of hitting the rope socket with a hammer or the like.
