[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a winding and unwinding device for laying power transmission cables, including a frame 1, a winding drum 2 is provided on the inner side of the frame 1, and a winding shaft 3 is provided at both ends of the winding drum 2. The winding shaft 3 is rotatably connected to the frame 1, and a first power group for controlling the rotation of the winding shaft 3 is provided on the outer side of the frame 1.

[0024] Two dustproof covers 7 are provided below the winding cylinder 2. A positioning seat 9 is slidably arranged between the two dustproof covers 7. A guide 8 is provided above the positioning seat 9. The guide 8 is detachably connected to the positioning seat 9. A through hole 19 is opened at the upper end of the guide 8. A cleaning sleeve 20 is provided in the through hole 19. Both ends of the cleaning sleeve 20 are provided with annular baffles 21 to prevent the cleaning sleeve 20 from falling off. The annular baffles 21 are placed outside the through hole 19.

[0025] The dust cover 7 is equipped with a second power unit for controlling the horizontal reciprocating movement of the positioning seat 9. The second power unit is connected to the first power unit through a transmission unit located inside the frame 1.

[0026] The dust cover 7 can shield against flying debris and provide protection for the second power unit.

[0027] The frame 1 is mounted on a mobile trolley. The first power unit controls the rotation of the reel 3. The reel 3 completes the winding and unwinding of the cable during rotation. During the rotation of the reel 3 controlled by the first power unit, the second power unit is driven to run synchronously through the transmission unit. During the operation of the second power unit, the positioning seat 9 is controlled to move horizontally back and forth. During the back and forth movement of the positioning seat 9, the guide 8 is used to guide the cable, so that the cable is evenly wound around the outside of the drum 2 or evenly unwinds the cable.

[0028] During the guiding process, the cable will come into contact with the cleaning sleeve 20 inside the guide 8. The cleaning sleeve 20 protects the cable, preventing direct contact between the cable and the guide 8 and thus avoiding damage to the cable sheath. As the cable passes through the cleaning sleeve 20, the cleaning sleeve 20 cleans the cable, removing small stones adhering to the cable surface and preventing them from getting tangled on the winding drum 2 and damaging the cable sheath. The guide 8 is fitted onto the outside of the cleaning sleeve 20 using a snap-fit ​​method. The bottom of the guide 8 is fixed to the positioning seat 9 via a detachable connection. This split design makes it easy for staff to replace the guide 8 and the cleaning sleeve 20, facilitating daily maintenance.

[0029] It is worth explaining in detail that the guide 8 has a pin plate 11 at its lower end, which is fixedly connected to the guide 8. The lower end of the pin plate 11 is inserted into a through groove at the upper end of the positioning seat 9, and the through groove is slidably connected to the pin plate 11. The outer side of the positioning seat 9 is provided with a positioning element to limit the sliding of the pin plate 11. When removing the guide 8 from the upper end of the positioning seat 9, after releasing the fixation between the pin plate 11 and the positioning seat 9 through the positioning element, the guide 8 is pulled upward to pull the pin plate 11 out of the through groove at the top of the positioning seat 9.

[0030] In a preferred embodiment, the positioning element includes a positioning bolt 17, which is mounted on the outside of the positioning seat 9. The positioning bolt 17 is screwed into the through groove and threadedly connected to the positioning hole on the outside of the pin plate 11. The outside of the pin plate 11 has multiple positioning holes, which are evenly arranged along the height of the pin plate 11.

[0031] Rotate the positioning bolt 17 on the outside of the positioning seat 9 and screw the positioning bolt 17 into the corresponding positioning seat 9 to lock the position of the guide 8. By changing the positioning seat 9 that cooperates with the positioning bolt 17, the height of the guide 8 can be adjusted, further increasing the flexibility of the guide 8 setting.

[0032] Regarding the first power unit:

[0033] The first power unit includes a motor 4, a first belt 5, and two first pulleys 6. The motor 4 is mounted on one side of the frame 1. The output end of the motor 4 is fixedly connected to one of the first pulleys 6, and the other first pulley 6 is fixedly connected to one end of the reel 3. The two first pulleys 6 are connected by the first belt 5.

[0034] The motor 4 is fixed to the frame 1. The motor 4 drives the first pulley 6 to rotate. The first pulley 6 will pull the other first pulley 6 to rotate through the first belt 5. Since the reel 3 is fixed to the first pulley 6, when the first pulley 6 rotates, the reel 3 will also rotate with the winding drum 2 to complete the winding and unwinding of the cable.

[0035] Regarding the second power unit:

[0036] The second power unit includes a reciprocating screw 13 and a nut seat 15. The reciprocating screw 13 is located inside the frame 1, and the left and right ends of the reciprocating screw 13 are rotatably connected to the frame 1. The nut seat 15 is sleeved on the outside of the reciprocating screw 13 and threadedly connected to the reciprocating screw 13. The upper end of the nut seat 15 is detachably connected to the positioning seat 9.

[0037] The helical groove on the outer side of the reciprocating screw 13 rotates alternately to the left and right. When the reciprocating screw 13 rotates one revolution, the nut seat 15 moves one lead in one direction. When the nut seat 15 moves to the reversing position of the helical groove of the reciprocating screw 13, it will be guided by the rotation change of the helical groove or the reversing mechanism to automatically change the direction of movement. Thus, the nut seat 15 can continuously and periodically reciprocate linearly without the reciprocating screw 13 rotating in the opposite direction.

[0038] To improve the stability of the nut seat 15 during horizontal movement, a limiting rod 14 is provided on the inner side of the frame 1. The left and right ends of the limiting rod 14 are fixedly connected to the frame 1. A sliding sleeve 16 is sleeved on the outer side of the limiting rod 14. The sliding sleeve 16 is slidably connected to the limiting rod 14 and fixedly connected to the nut seat 15.

[0039] When the nut seat 15 moves horizontally along the reciprocating screw 13, the sliding sleeve 16 fixed to the nut seat 15 will also slide along the rod of the limit rod 14. The sliding sleeve 16 guides the nut seat 15 by cooperating with the limit rod 14, ensuring that the nut seat 15 will not deflect when it slides along the rod of the reciprocating screw 13.

[0040] The positioning seat 9 is fixed to the upper end of the nut seat 15 by a bolt connection. Specifically, the lower end of the positioning seat 9 is provided with a bolt plate 22, which is fixedly connected to the positioning seat 9. Multiple fixing bolts 18 are mounted on the bolt plate 22, passing through the bolt plate 22 and threadedly connected to bolt holes opened at the upper end of the nut seat 15. When removing the positioning seat 9 from the upper end of the nut seat 15, simply rotate the fixing bolts 18 on the bolt plate 22 to unscrew them from the bolt holes at the top of the nut seat 15.

[0041] Regarding the transmission assembly:

[0042] The transmission assembly includes a second belt 12 and multiple second pulleys 10. The second belt 12 and the second pulleys 10 are located inside the frame 1. Each second pulley 10 is fixedly mounted at the left and right ends of the winding shaft 3 and the reciprocating screw 13, respectively. Adjacent second pulleys 10 are connected by the second belt 12. After the first power assembly drives the winding shaft 3 and the drum 2 to rotate, the second pulleys 10 fixed to the winding shaft 3 will drive another set of second pulleys 10 to rotate via the second belt 12. The second pulleys 10 control the rotation of the reciprocating screw 13 during rotation, thereby achieving rotational control of the reciprocating screw 13.

[0043] To facilitate the display of the power unit and transmission unit, the dust cover 7 on the outer and inner sides of the frame 1 is in a removed state. During the assembly process, the dust cover 7 will be fixed to the inner and outer sides of the frame 1 by connecting bolts to cover and protect the first power unit and transmission unit.

[0044] How this application works:

[0045] The frame 1 is mounted on a mobile trolley. The first power unit controls the rotation of the reel 3, which winds and unwinds the cable during rotation. While the first power unit controls the rotation of the reel 3, it drives the second power unit synchronously via a transmission unit. During operation, the second power unit controls the horizontal reciprocating movement of the positioning seat 9. As the positioning seat 9 reciprocates, it uses the guide 8 to guide the cable, ensuring it is evenly wound around the outside of the winding drum 2 or evenly unwound. During this guiding process, the cable comes into contact with the cleaning sleeve 20 inside the guide 8. The cleaning sleeve 20 protects the cable, preventing direct contact and damage to the cable sheath. As the cable passes through the cleaning sleeve 20, it cleans the cable, removing small stones adhering to its surface and preventing them from becoming entangled on the winding drum 2 and damaging the cable sheath.
