[0002] When protecting cables, in order to prevent them from being damaged, the cables are passed through pipes to protect them. In existing threading devices, the traction line is generally passed through the pipe first, and then the cables are fixed on the traction line. The traction line is dragged to drive the cables to move, and the cables are passed through the pipe. When fixing, such as the patent authorization announcement number CN 219998908U, the authorization announcement date is 2023.11.10, and the name is a construction power construction pipeline threading device. When the fixed hoop and the movable hoop are combined, the bolts and nuts are installed on the end plate, and the nuts are tightened so that the fixed hoop and the movable hoop cooperate with the inner layer to hold the outer surface of the cable end tightly. Since the fixation relies entirely on the friction during clamping, it is easy to cause the cable to detach, affecting the threading process and resulting in a waste of time. Utility Model Content

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1: Reference Figure 1-3, a municipal pipeline threading device includes a steel wire rope 1, a guide part 2 is connected to one end of the steel wire rope 1, and a fixing part 3 is fixedly connected to the other end of the steel wire rope 1. The fixing part 3 includes a connecting column 7, which is fixedly connected to the steel wire rope 1, and a plurality of hinged seats 5 are fixedly connected to the connecting column 7 at equal distances around the circumference. A plurality of hinged seats 5 are hingedly connected to a rotating part 4, and a plurality of rotating parts 4 are fixedly connected to an insertion nail 6. The plurality of insertion nails 6 are rotated by an abutment mechanism. When the cable is fixed, the abutment mechanism moves downward, which will cause the rotating part 4 to rotate so that the insertion nail 6 on the rotating part 4 is inserted into the cable, thereby connecting and fixing the cable, enhancing the fixing effect, avoiding the situation where the cable is detached during threading, and ensuring the threading process.

[0019] The rotating part 4 includes a vertical part, on which an inclined part is fixedly connected, and the inclined part is hinged to the hinge seat 5. The abutment mechanism includes a connecting column 7 on which a movable ring 11 is provided. The movable ring 11 is moved by a moving mechanism. Rollers 8 are fixedly connected to the movable ring 11 at equal distances on the circumference. Multiple rollers 8 are respectively in abutment with the inclined part. When the movable ring 11 is moved, the rollers 8 are moved, which will cause the inclined part to rotate, so that the insertion nail 6 moves toward the defense line close to the axis of the connecting column 7, so that the insertion nail 6 can be inserted into the cable.

[0020] The moving mechanism includes a connecting ear 10, which is fixedly connected to the connecting column 7. A threaded rod 9 is connected to the connecting ear 10 through a thread, and a torsion block is provided on the threaded rod 9. The threaded rod 9 is rotatably connected to the moving ring 11 through a bearing. By rotating the threaded rod 9, the position of the threaded rod 9 in the connecting ear 10 is adjusted to drive the moving ring 11 to move.

[0021] When in use, first pass the wire rope 2 through the pipe, then put the cable head into multiple rotating parts 4, move the moving ring 11, move the roller 8, rotate the inclined part, and move the insertion nail 6 toward the defense line close to the axis of the connecting column 7, insert the insertion nail 6 into the cable, fix the cable, pull the wire rope 2, and the wire rope 2 will pass through the pipe with the cable, and finally move the moving ring 11 to reset, press the rotating part 4 to pull the insertion nail 6 out of the cable, and separate the cable from the fixing part 3 to complete the threading.

[0022] Example 2: In Example 1, the steel wire rope 2 and the fixing portion 3 are fixedly connected. When the steel wire rope 2 is broken or damaged, or when the fixing portion 3 is damaged, it cannot be replaced, which easily leads to a waste of resources. Figure 1-3As another preferred embodiment of the present invention, based on embodiment 1, a threaded through hole is provided in the connecting column 7, a bolt 12 is threadedly connected to the threaded through hole, the wire rope 1 is inserted into the threaded through hole and fixedly connected with the bolt 12, the bolt 12 is a rust-proof bolt, and the steel rope 1 and the fixing part 3 can be disassembled and replaced and repaired by loosening the bolt 12, thereby avoiding waste of resources.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
