The position of the anti-bias parts is adjusted according to the different sizes of the cables. The support seat 103 carries the rolling rod 104, and the cable passes over the wire roller 105 and upwardly abuts the abutment according to the different sizes of the cables. The top plate 102 is now in the sliding direction of the telescopic rod 107, and the telescopic rod 107 slides upward and lifts the limit block 106, and the spring 108 is compressed so that the abutment fits the cable. When the cable towing operation is performed, the anti-bias part cooperates with the abutment part to prevent the cable from shaking. When the cable towing operation is performed, the limit block 106 is used to prevent the abutment from contacting the wire roller 105.

The fixed plate 112 prevents the threaded rod 114 from tilting.

[0026] At the same time, the connecting block 115 is rotatably connected to the threaded rod 114 and is located on the outside of the threaded rod 114, the clamping seat 116 is fixedly connected to the connecting block 115 and is located on the outside of the connecting block 115, the anti-skew wheel 117 is rotatably connected to the clamping seat 116 and is located on the outside of the clamping seat 116, the connecting block 115 fixes the clamping seat 116, the clamping seat 116 fixes the anti-skew wheel 117, and the anti-skew wheel 117 fits the side of the cable, thereby effectively preventing the cable from shaking left and right during the towing operation.

[0027] In addition, the fixing frame 101 has a slide groove 118 adapted to the slide rod 111. The slide rod 111 prevents the support frame 109 from being offset when moving through the slide groove 118, thereby improving the stability of the movement of the support frame 109 and allowing the wire pressing roller 110 to be more stably supported against the cable.

[0028] The adjustable towing cable device for a coal mining machine using the present embodiment is provided with a top plate 102, two support seats 103, a rolling rod 104, a conductor roller 105 and an adjusting component. When it is used, the rotating disk 113 is rotated, the threaded rod 114 rotates in the connecting block 115, and pushes the clamping seat 116 to move, and the position of the anti-deviation wheel 117 is adjusted according to the size of the cable. The cable passes over the conductor roller 105, and the wire pressing roller 110 is supported upward according to the different sizes of the cable. The support frame 109 moves upward, the sliding rod 111 slides in the sliding groove 118, the telescopic rod 107 slides upward, and the spring 108 is compressed to make the wire pressing roller 110 fit the cable. In this way, the clamping position of the device can be adjusted according to the different sizes of the cable during the towing operation, which is convenient for adapting to cables of different types and improving the flexibility and convenience of the use of the device.
