The traveling roller 11 provided on the outside of the pipe threading auxiliary ring 1 is used to assist in cable laying. When the staff places the pipe threading auxiliary ring 1 on the outside of the cable and fixes the cable and the pipe threading auxiliary ring 1, the pipe threading auxiliary ring 1 and the cable can be placed inside the pipe. At this time, when the staff pulls the cable, the cable will move with the assistance of the pipe threading auxiliary ring 1 and the traveling roller 11, so as to avoid the situation where the friction between the cable and the inner wall of the pipe is large. The two clamping rings 2 sliding on the inner side of the pipe threading auxiliary ring 1 are used to clamp and fix the cable, so that the cable can be fixed on the inner side of the pipe threading auxiliary ring 1, and the cable laying work is completed with the assistance of the pipe threading auxiliary ring 1 and the traveling roller 11. The extended fixing seats 3 fixed on both sides of the pipe threading auxiliary ring 1 are used to The extension base 3 is provided with a plurality of fixing members 31, 32 and 33, and the fixing members 31 are provided with a plurality of fixing members 31, 32 and 33, respectively.
[0018] A connecting rod 12 is fixedly connected between the pipe threading auxiliary ring 1 and the traveling roller 11, and threaded holes 13 are provided inside the two pipe threading auxiliary rings 1; the connecting rod 12 fixed between the pipe threading auxiliary ring 1 and the traveling roller 11 is used to provide support for the traveling roller 11, so that the traveling roller 11 can slide on the inner wall of the pipe, thereby assisting the movement of the pipe threading auxiliary ring 1 and the cable, reducing the friction between the cable and the pipe, and avoiding wear of the cable during laying.
[0019] The outer sides of the two clamping rings 2 are fixedly connected with threaded rods 21, and the threaded rods 21 are rotatably connected to the pipe threading auxiliary ring 1 through the threaded holes 13; the threaded rods 21 fixed on the outer sides of the clamping rings 2 are used to adjust the position of the clamping rings 2. The staff can rotate the threaded rods 21 inside the threaded holes 13 to change the vertical position of the clamping rings 2, thereby completing the clamping work of cables of different specifications, so that the cables can be fixed inside the pipe threading auxiliary ring 1.
[0020] A telescopic rod 34 is fixedly connected between the positioning block 31 and the steering roller 32, and a clearance groove 35 is opened inside the extension fixing seat 3, and the adjustment rod 4 slides inside the clearance groove 35; the telescopic rod 34 fixed between the positioning block 31 and the steering roller 32 is used to provide support for the steering roller 32, so that the steering roller 32 can slide on the inner wall of the pipeline to complete the work of assisting the movement of the pipe threading auxiliary ring 1, and the telescopic rod 34 is telescopically set and has a spring installed inside, so that when the pipe threading auxiliary ring 1 passes through the bend of the pipeline, the steering roller 32 can continue to be close to the pipeline, thereby ensuring that the steering roller 32 can provide assistance for the stable movement of the pipe threading auxiliary ring 1.

[0022] The working principle and use process of the utility model are as follows: when the staff needs to lay cables, they need to first move the two pipe threading auxiliary rings 1 close to each other according to the diameter of the pipe. When the pipe threading auxiliary ring 1 moves, it will drive the extension fixing seat 3 and the adjustment rod 4 to move synchronously. At this time, the adjustment rod 4 will be inserted into the extension fixing seat 3 located below. After the staff adjusts the two pipe threading auxiliary rings 1 to a suitable distance, the extension fixing seat 3 can be fixed by inserting the limit block 33 into the adjustment rod 4, so that the two pipe threading auxiliary rings 1 can continue to maintain a suitable distance and can be placed in the pipe. Then the staff can place one end of the cable in the clamp The inside of the ring 2, and then the staff can rotate the threaded rod 21 to the appropriate position according to the actual specifications of the cable. When the threaded rod 21 rotates, it will drive the clamping ring 2 to move vertically, so that the two clamping rings 2 are in contact with the cable, and the cable is fixed. At this time, the staff can pull the pipe threading auxiliary ring 1 through a winch, so that the pipe threading auxiliary ring 1 drives the cable to move on the inner wall of the pipe, and the traveling roller 11 and the auxiliary roller 32 of the pipe threading auxiliary ring 1 will assist the movement when it moves, so as to ensure the stability of the pipe threading auxiliary ring 1 when it moves inside the pipe, reduce the friction between the cable and the inner wall of the pipe when it moves, and prevent the cable from being worn.
