[0033] The two limiting wheels 7 are distributed in an up-down manner.

[0034] By Figure 1 - Figure 3 It can be known that the guide structure 83 comprises a fixed plate 831, a sliding block 833, a screw rod 834 and a fastening nut 835, the fixed plate 831 is provided with two, and a plurality of movable guide wheels 832 are movably inserted between the two fixed plates 831, the sliding block 833 is fixedly connected to the bottom end of the bottom fixed plate 831, the screw rod 834 is fixedly connected to the bottom end of the sliding block 833, the fastening nut 835 is threadedly connected to the outer surface of the screw rod 834, and the sliding block 833 is movably inserted into the sliding limiting groove 82.

[0035] As can be seen, the end of the cable is penetrated between the two guide structures 83, the fixed plate 831 is moved, the sliding block 833 is driven to slide in the sliding limiting groove 82, and the sliding block 833 is fixed by the fastening nut 835 after being moved to the appropriate position, so that the left and right movement ranges of the cable are limited. The cables on both sides of the wire roller 4 are in close contact with the movable guide wheels 832 on both sides during the movement, so that the cables are limited and guided. The movable guide wheels 832 rotate between the fixed plates 831 due to friction during the movement of the cable, so that the flexibility of the cable is improved, and the wear of the cable is reduced.

[0036] Preferably, the fixed plates 831 are arranged in an arc-shaped structure, and the bottom fixed plate 831 is in close contact with the top end of the fixed support 81.

[0037] As can be seen, the fixed plates 831 are arranged in an arc-shaped structure, and the movable guide wheels 832 are installed according to the arc-shaped structure of the fixed plates 831, so that the cables can be limited and guided.

[0038] Embodiment two:

[0039] Reference Figure 4 As shown, the output end of the driver 56 is fixedly connected to one end of the supporting wheel 55, and the inner walls of the fixed frame 51 are fixedly connected to the two ends of the supporting frame 6.

[0040] As can be seen, the screw rod 52 is rotated, the screw rod 52 is rotated in the fixed frame 51 and is moved downward, the movable seat 53 drives the compression wheel 54 to be displaced downward, the compression wheel 54 is in close contact with the outer surface of the cable below, the driver 56 is started, the output end of the driver 56 drives the supporting wheel 55 to rotate, the supporting wheel 55 drives the cable in close contact therewith to move, so that automatic traction and movement of the cable are realized during the laying of the cable, the labor intensity of workers is reduced, and the work efficiency is improved.

[0041] The output end of the driver 56 is fixedly connected with the supporting wheel 55, so that the supporting wheel 55 is rotated when the driver 56 is started.

[0042] Further, the design application is applied to the cable laying process of a coal mine cable, the wire roller 4 with the cable is inserted between the two supporting plates 3, then the end of the cable penetrates the gap between the two guide structures 83 and is further inserted into the space between the compression wheel 54 and the supporting wheel 55. As the cable is continuously pulled, it smoothly penetrates the channel set between the two limiting wheels 7. At this time, the screw rod 52 is rotated stably in the fixed frame 51 and gradually pushed downward, the movable seat 53 connected with the screw rod 52 is synchronously moved downward, and the downward movement of the movable seat 53 further causes the compression wheel 54 to be in close contact with the outer surface of the cable, so that the movement range of the cable in the vertical direction is effectively limited.

[0043] Next, the position of the fixed plate 831 is adjusted, so that the slider 833 moves smoothly in the sliding limiting groove 82, at the same time, the slider 833 also drags the screw rod 834 to slide synchronously in the sliding limiting groove 82, when moving to the preset ideal position, it is locked firmly through the fastening nut 835, in this way, the moving range of the cable in the horizontal direction is also accurately limited;
