[0002] During construction, various electrical lines need to be set up inside the structure. When laying the electrical lines, in order to protect the cables and increase their service life, the cables are usually installed in protective tubes. During operation, the protective tubes need to be installed first, and then the cables are passed through the protective tubes. This operation process is called threading.

[0003] The threading method in the prior art is that a worker usually passes a steel wire through a pipe first, and another worker ties a cable on the end of the steel wire. One worker pulls the steel wire while the other worker passes the cable into the pipe. The entire threading process is not only labor-intensive, but also inefficient, time-consuming and labor-intensive. Summary of the invention

When threading the cable, the first motor is started to drive the winding roller to rotate and unwind, and the driving mechanism drives the driving roller and the driven roller to rotate in opposite directions. The cable is driven for transportation under the drive of friction, so that the cable output end moves forward in the protective tube and guides the transported cable through the guide head, thereby realizing automatic threading of the cable, reducing the trouble of manual threading, and improving the efficiency of threading work.

[0010] By adopting the above technical solution, the output end of the cable is passed through the fixed ring and the rotating ring. When the cable is threaded, the driving roller drives the rotating ring and the oil pipe to rotate through the rotating mechanism. During the cable feeding process, the pump body is started to transport the lubricant into the cavity. The lubricant enters the oil pipe and is then sprayed out through the nozzle. During the rotation of the rotating ring and the oil pipe, the nozzle sprays the lubricant on the outer peripheral surface of the cable, thereby reducing the friction between the cable and the inner wall of the protective tube, reducing the resistance during cable laying, and improving the cable threading efficiency.

[0015] Preferably, the end of the guide head is provided with a mounting hole for inserting the cable; the inner side wall of the mounting hole is provided with a group of threaded through holes in the radial direction; and a group of threaded rods are threadedly connected on the inner side walls of the threaded through holes.

[0016] By adopting the above technical solution, the cable output end is inserted into the installation hole, and then the threaded rod is rotated to press against the outer wall of the cable, thereby realizing the installation of the guide head on the cable output end, so that the guide head can guide the cable conveyed into the protective tube.

In addition, the cooperation of the slide plate, the slide rod and the spring can make the guide head adapt to protective tubes of different diameters, so that the guide head can move in protective tubes of different diameters to guide the cable threading.

[0019] Preferably, a cleaning brush located on a side of a group of sleeves away from the mounting hole is threadedly connected on the outer peripheral surface of the guide head.

[0020] By adopting the above technical solution, when the guide head and the cable move in the threading tube to perform the cable threading work, the cleaning brush arranged on the outer wall of the guide head can clean the dust and impurities on the inner wall of the protective tube, thereby reducing the wear of the outer layer of the cable during the threading process.

During the cable feeding process, the lubricant in the cavity is sprayed onto the outer surface of the cable through the nozzle, reducing the friction between the cable and the inner wall of the protective tube, reducing the resistance to cable movement, and improving the cable threading efficiency.

[0024] In summary, this application has the following beneficial effects: 1. Pull out the cable output end on the winding roller, install the guide head, and place it in the protective tube.

A driving mechanism 4 is provided on the outer wall of the second support frame 34, which can drive the driving roller 35 and the driven roller 36 to rotate in opposite directions. The driving mechanism 4 includes a second motor 41, a first spur gear 42 and a second spur gear 43. The second motor 41 is horizontally installed on the outer wall of the second support frame 34. The output end of the second motor 41 is coaxially fixed to the driving roller 35.

A ball 28 is arranged on the outer surface of the guide head 2 to contact the inner wall of the protective tube under the cooperation of the slide plate 26, the slide rod 27 and the spring 25. When the cable is threaded, the ball 28 rolls to drive the guide head 2 forward. The sliding friction between the guide head 2 and the inner wall of the protective tube is converted into rolling friction through the rolling of the ball 28, thereby reducing the resistance of the guide head 2 when moving. During the movement of the guide head 2, the cleaning brush 29 cleans the inner wall of the protective tube to reduce the influence of dust and impurities on the degree of wear of the cable threading.

During the rotation of the rotating ring 6 and the oil pipe 61, the nozzle 62 sprays the lubricant on the outer peripheral surface of the transported cable, reducing the friction between the cable and the inner wall of the protective tube when the cable moves in the protective tube, reducing the resistance during cable laying, and improving the cable threading efficiency.

[0038] like Figure 1 and Figure 7 As shown, the rotating mechanism 7 includes a rotating shaft 71, a first bevel gear 72, a second bevel gear 73, a ring gear 74 and a third spur gear 75.

[0039] Under the meshing cooperation of the first bevel gear 72 and the second bevel gear 73, the driving roller 35 drives the rotating shaft 71 and the third spur gear 75 to rotate during the rotation. Under the meshing cooperation of the third spur gear 75 and the ring gear 74, the rotating shaft 71 drives the rotating ring 6 to rotate, thereby realizing the transmission of kinetic energy during the rotation of the driving roller 35, so that the lubricant can be sprayed on the outer peripheral surface of the feed cable.

During the cable feeding process, the driving roller 35 drives the rotating ring 6 and the oil delivery pipe 61 to rotate through the rotating mechanism 7, so that the lubricant in the cavity 51 is sprayed on the outer peripheral surface of the cable through the nozzle 62, thereby reducing the friction between the cable and the inner wall of the protective tube, reducing the resistance of the cable movement, and improving the cable threading efficiency; S4: After the threading process, the electric push rod 52 is started to drive the blade 53 to move downward to cut the cable so that the remaining cable can be rolled up for later use.

During the threading process, the guide head 2 guides the cable moving in the protective tube, and the cleaning brush 29 cleans the inner wall of the protective tube during the movement of the guide head 2. After the guide head 2 passes through the protective tube, the guide head 2 is removed from the cable, and the electric push rod 52 is started to drive the blade 53 to move down and cut the cable, thereby realizing the automatic threading of the cable, reducing the labor intensity of manual labor, and improving the efficiency of cable threading. When the driving roller 35 rotates to feed and transport the cable, the driving roller 35 drives the rotating ring 6 and the oil pipe 61 to rotate through the rotating mechanism 7. During the rotation of the rotating ring 6, the pump body 37 is started to transport the lubricant to the cavity 51. The lubricant in the cavity 51 enters the oil pipe 61 and is sprayed out through the nozzle 62. During the rotation of the rotating ring 6, the nozzle 62 sprays the lubricant on the outer peripheral surface of the feeding and transporting cable, thereby reducing the friction between the cable and the inner wall of the protective tube when the cable moves in the protective tube, reducing the resistance to the movement of the cable, and improving the cable threading efficiency.
