BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire rope twist prevention device for a winch device.

[0002]

2. Description of the Related Art FIG. 3 shows a conventional vehicle winch device. Here, 1 is a working vehicle equipped with a main winch and a sub winch, 2 is an object to be recovered (collected vehicle), 3 is a wire rope of a sub winch, 4 is a wire rope of a main winch, 5
Is a sheave (large), 6 is a sheave (small), and 7 is a sheave for connecting the auxiliary winch wire rope and the sheave (large).

In this structure, the object to be recovered (vehicle to be recovered)
In order to recover 2, the work vehicle 1 must connect the wire rope 4 of the main winch to the recovered vehicle 2. In particular, depending on the working conditions, the main winch wire rope 4 may be used in a compound rope state as shown in the figure. In such a case, it is necessary to carry the main winch wire rope 4 and the sheave (large) 5 to the recovered vehicle 2, and the sub winch is used for pulling out the main winch wire rope 4.

The problem here is that when each element is connected as shown in FIG. 3, when the auxiliary winch wire rope 3 is wound up and tension is applied, the auxiliary winch wire rope 3 has a characteristic of the wire rope to rotate. (Force to return the twist of the wire rope) is generated. The rotation force causes the main winch wire rope 4 including the sheave (large) 5 to be twisted.

This twist not only hinders the work, but also causes a kink in the wire rope and contributes to rope damage.

[0006]

[Problems to be solved by the invention] Since the wire rope twist is a cause of shortening the life of the rope and presents a safety problem, the wire rope twist is prevented when the main winch wire rope is pulled out from the auxiliary winch wire rope. There is a need to.

[0007]

[Means for Solving the Problems] At the portion of the sheave connecting the auxiliary winch wire rope to the sheave of the main winch,
A twist prevention tool is attached to prevent the relative rotation of the sheave and the sub winch wire rope.

[0008]

[Operation] By attaching the wire rope twisting preventive device to the sheave part that connects the sheave of the main winch wire rope and the sub winch wire rope for pulling out,
Rotation of the shelter is prevented, and thus twisting of the main winch wire rope is prevented.

[0009]

1 and 2, 1 is a working vehicle, 2 is an object to be recovered (collected vehicle), 3 is a wire rope of a sub winch, 4 is a wire rope of a main winch, and 5 is a sheave (large). , 6 is a sheave (small), 7 is a shelter for connecting the auxiliary winch wire rope and the sheave (large), 8 is a twist preventive tool (whole), 8a is a hook through which the auxiliary winch wire rope is passed, and 8b is combined with the sheave A U-shaped portion 8c for holding the fixing bolt for closing the open end of the U-shaped portion.

The members 1 to 7 are the same as those in the prior art shown in FIG. 3, and 8 is the anti-twist device according to the present invention. When the sub winch wire rope 3 is wound to pull out the main winch wire rope 4, tension is generated in the sub winch wire rope 3 and the main winch wire rope 4 due to the weight of the main winch wire rope 4 and the resistance of the main winch device. To do. This tension causes the sub winch wire rope 3 to rotate, and the main winch wire rope is twisted.

In the present invention, when the wire ropes 3 and 4 are connected, the auxiliary winch wire rope 3 is passed through the hook 8a of the anti-twist device 8 and the other end of the twist device is U-shaped 8b and the fixing bolt 8c. The main winch wire rope including the sheave (large) 5 can be prevented from being twisted by fixing it to the sheave 7 via the.

[0012]

The wire rope twist prevention device according to the present invention has a main winch and a sub winch installed in a work vehicle, a sheave (small) is attached to an object to be recovered, and the sheave (small) is folded back through the sub winch. In a winch device for a vehicle, in which a winch wire rope is connected to a sheave (large) of a main winch wire rope via a shelves, a U-shaped portion and a fixing bolt connected to the sheave portion, and a U-shaped portion projectingly provided on the U-shaped portion. By having a hook through which the auxiliary winch wire rope is passed and preventing twisting of the wire rope, the following effects are obtained.

(1) It is possible to prevent a twist when the wire rope is pulled out. (2) The life of the wire rope is improved.
