There is wire rope distortion of knoing to current endless rope winch or other modes traction tow rope in-process, causes the wire rope to bounce-back and hinders people, the impaired phenomenon of knotting of wire rope, the utility model aims to provide an automatic rotatory knotting prevention device, the device simple structure, solved the rotatory problem that causes of tow rope process wire rope, avoided personnel injured and wire rope damage.

The working principle is as follows: and fixedly connecting the rope head of the steel wire rope with the second hoisting ring, and connecting the first hoisting ring with the side of the towing rope. When dragging the rope, wire rope produces the rotation, and the circulator in this device can be rotatory along with wire rope this moment, and then has dissolved the rope strength, and the lead screw can not rotate owing to be connected through bearing and circulator, consequently drags the rope side and can not receive any influence, has ensured that the dragging rope can not take place to tie a knot the distortion, has effectively avoided the problem that the wire rope rotation brought.

Furthermore, the base is composed of two square steel plates which are respectively welded on the other side of the base and are arranged in parallel at a certain distance; the two square steel plates are vertical to the surface of the base; and one ends of the two square steel plates, which are opposite to the base, are provided with notches, and the second hoisting ring part is inserted into the two notches and is welded and fixed with the square steel plates.

The base is used for connecting the rotator and the second lifting ring, and the connection mode is simple and firm in connection.

Furthermore, the base is of a square plate structure, and the through hole is formed in the center of the square plate; the two square steel plates are respectively close to two opposite side edges of the square structure and are welded.

The rotator has the advantages of simple structure, low manufacturing cost and firm structure, and is suitable for batch production.

The utility model discloses an install autogiration additional between wire rope fixed point and draw gear, when dragging the rope, wire rope produces the rotation, and the circulator rotates and has further dissolved the rope strength, and wire rope stops the rotation, has stopped to drag the rope in-process wire rope phenomenon of knoing, has solved wire rope and has hindered people and the impaired phenomenon of wire rope.
