[0022] Specifically, the path of the trolley 2 adopts a spliced ​​track 1, which can be adjusted according to the length of the tower and fixed with a clamp at the edge of the tower to prevent the track deviation of the trolley 2 during operation, resulting in unstable wiring length. The baffle 11 plays a guiding role in the movement of the trolley 2. When working, first fix the cable drum on the installation mechanism 4. The on-site electrical wiring is coordinated by two people, one of whom is at the cable drum and the other is at the tower. The two people are respectively located at the two ends of the spliced ​​track 1. The person at the cable drum controls the forward and backward movement of the trolley 2 by manual operation. After the cable drum is fixed, Fix one end of the cable on the cable reel on the fixing mechanism 3 so that the trolley 2 can drive the cable to move, and then start the trolley 2 to move along the spliced ​​track 1. When the trolley 2 moves to the end of the spliced ​​track 1, another person controls the trolley 2 to stop and sends a signal to the person at the cable reel. After receiving the signal from the person at the tower, the person at the cable reel cuts the cable pulled out by the trolley 2, and then the person at the tower releases the cable through the fixing mechanism 3. After releasing the cable, the person at the tower controls the trolley 2 to return to its original position along the spliced ​​track 1, and repeats the back and forth process to complete the cable wiring work.

[0023] The present invention cooperates with the spliced ​​track 1, the trolley 2 and the fixing mechanism 3, and the cable can be pulled out and moved to the desired position through the trolley 2. The staff only needs to cut the cable, control the trolley 2 to return to the original path, and repeat the above operation to complete the wiring, thereby reducing the wiring team of four to six people to two people, and there is no need to equip components such as hand winches, which greatly saves working hours and improves work efficiency. At the same time, it ensures the safety of personnel, reduces personnel investment, reduces labor costs, and ensures the working effect of the device.

[0024] like Figure 2As shown, in one embodiment, the trolley 2 includes a shell 21, and a plurality of rotating shafts 22 are rotatably connected inside the shell 21, both ends of the rotating shafts 22 extend to the outside of the shell 21 and are sleeved with wheels 23, the fixing mechanism 3 is detachably connected to the outer wall of the shell 21 through a hook 24, and a driving mechanism for driving one of the rotating shafts 22 to rotate is provided inside the shell 21, and the driving mechanism includes a motor 25 provided inside the shell 21, and a first gear 26 is sleeved on the outer wall of one of the rotating shafts 22, and a second gear 27 is provided on the output end of the motor 25 on one side of the first gear 26, and the second gear 27 is meshed with the first gear 26, and a heat dissipation fan 28 is provided on the inner wall of the shell 21 on one side of the motor 25.

When the trolley 2 moves, the motor 25 can be started, and the motor 25 drives the second gear 27 to rotate, and the second gear 27 drives the first gear 26 to rotate, thereby driving one of the rotating shafts 22 to rotate, and the corresponding two wheels 23 rotate with the rotating shaft 22, thereby driving the trolley 2 to move, so that the trolley 2 can move along the spliced ​​track 1 to complete the cable wiring work; optionally, the motor 25 is a servo motor, and the first gear 26 and the second gear 27 are both bevel gears. When the trolley 2 moves, the cooling fan 28 moves at the same time to dissipate heat for the motor 25, thereby ensuring the stability of the device during operation. The fixing mechanism 3 is hung on the housing 21 through the hook 24, so that the fixing mechanism 3 is easy to disassemble, thereby ensuring the convenience of the device.

[0026] In one embodiment, a position sensor 5 is provided at one end of the spliced ​​track 1, and the position sensor 5 is electrically connected to the motor 25, and an encoder is provided on one side of the outer wall of one of the mounting brackets 41.

[0027] Specifically, the position sensor 5 is located at the end of the spliced ​​track 1 away from the cable drum, with the end of the spliced ​​track 1 close to the cable drum as the starting point and the end close to the tower as the end point. When the trolley 2 drives the cable to move to the end point, the trolley 2 moves to one side of the position sensor 5, and the position sensor 5 controls the motor 25 to cut off the power, thereby stopping the movement of the trolley 2. There is no need for personnel to control the stopping of the trolley 2, thereby ensuring the convenience of the device. In addition, the present application uses an encoder to check the length of the cable pulled out by the trolley 2. Combined with the above-mentioned position sensor 5, the present application uses an encoder and a position sensor 5 to prevent the cable outlet length from being inconsistent and the wiring position from being uneven, which does not meet the process requirements and leads to cable waste, thereby ensuring the working effect of the device.

[0029] Specifically, the relative distance between the two mounting frames 41 can be adjusted according to actual work requirements. When the adjustment work is in progress, the slide bar 45 and the sleeve 46 slide relative to each other, and the support rod 47 and the support tube 48 slide relative to each other. When the adjustment of the two mounting frames 41 is completed, the position of one of the first openings is aligned with the position of one of the second openings, and the second pin can be fixed to the corresponding first opening and second opening to fix the relative position of the slide bar 45 and the sleeve 46, thereby completing the distance adjustment work of the two mounting frames 41. The support rod 47 and the support tube 48 play a supporting role for the two mounting frames 41. Use; similarly, the slider 43 and the fixed block 42 can be controlled to slide relative to each other, and the fourth opening can be aligned with the position of one of the third openings, so as to adjust the height of the perforating shaft 44. When the perforating shaft 44 is adjusted to the required height, the second pin can be fixed in the corresponding third opening and fourth opening to complete the adjustment of the perforating shaft 44. The cable drum is installed on the outer wall of the perforating shaft 44; the present application can adjust the relative distance between the two mounting frames 41 and adjust the height of the perforating shaft 44, so that the present application is compatible with cable drums of various specifications and models, thereby ensuring the practicality of the present device.

[0031] When in use, the first fastener 31 and the second fastener 32 are assembled, and one end of the cable is passed through the through hole, and the cable is located on one side of the arc block 33. Then, the cable on one side of the arc block 33 is wrapped and tightened multiple times by the flexible rubber belt 34. Finally, the other end of the flexible rubber belt 34 is fixed to the first pin 35, so that the cable is fixed inside the through hole. Finally, the pull ring 36 is put on the hook 24, so that the trolley 2 can drive the cable to move; when the cable needs to be removed, only the first pin 35 needs to be removed, which ensures the convenience of the present application.
