The cable auxiliary equipment often needed in power construction is the cable winding and unwinding device, that is, to wind and unwind the cable. The existing cable winding and unwinding device has a simple structure, consisting of a wire roller and a hand-cranking structure. The cable is wound around the wire roller by manually cranking, and the unwinding operation is also carried out by manually cranking. The existing cable winding and unwinding device requires manual operation for winding and unwinding, which is time-consuming and laborious. At the same time, the functions achieved are relatively simple and cannot meet the existing winding and unwinding operations. For example, it cannot meet the need to adjust the winding and unwinding angle while winding and unwinding in a complex operating environment.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Refer to Figures 1-6Figure, the present utility model provides a technical solution: a cable winding and unwinding device, including a base 1, a rotating mechanism is arranged in the middle of the base 1, and the upper end of the rotating mechanism is connected with a bottom plate 31. A detachable winding and unwinding turntable 7 is installed on one side of the bottom plate 31, and a second motor 32 is installed on the other side of the bottom plate 31. The second motor 32 drives the winding and unwinding turntable 7 to rotate to complete winding and unwinding. A wire pressing mechanism is arranged above the winding and unwinding turntable 7, and the wire pressing mechanism is an elastic telescopic wire pressing structure. Four rollers 12 are installed at the bottom of the base 1, and an electric push rod 10 is installed between the rollers 12. A support plate 11 is arranged at the bottom of the electric push rod 10. A pull rod 4 is arranged at one end of the base 1, and a handle 5 is fixedly clamped at the upper end of the pull rod 4. The handle 5 and the rollers 12 facilitate the overall movement of the device. At the same time, after determining the fixed position, the electric push rod 10 is used to push the support plate 11 to support the ground, ensuring the stability of the base during the winding and unwinding operation.

[0028] Referring to Figure 2 , Figure 3 , the rotating mechanism includes a vertical plate 2. The vertical plate 2 is installed above the base 1. A first motor 34 is arranged inside the vertical plate 2. A gear 25 is arranged at the output end of the first motor 34, and one side of the gear 25 is connected with the bottom shaft 3 through another gear. The bottom of the bottom shaft 3 is connected with the housing through a bearing seat 35. The top of the bottom shaft 3 extends out of the vertical plate 2 and is connected with the bottom plate 31. The first motor 34 drives the bottom shaft 3 to rotate through the meshing gear 25 structure, so as to realize the arbitrary angle rotation of the device main body connected above the bottom shaft 3, adapting to the winding and unwinding operations under different operating environments; a fixing plate 36 is arranged in the middle of the bottom plate 31, and a storage box 24 is arranged at one end of the fixing plate 36. Limiting card slots are arranged at both ends of the vertical wall of the storage box 24, and the limiting card slots are matched with the layer board 20. The storage box 24 can adopt a conventional drawer structure, which is convenient for storing auxiliary tools for work.

[0029] Specifically, a second motor 32 is installed above the laminate 20, and the rotating shaft of the second motor 32 penetrates through the inside of the fixing plate 36 and is fixedly connected to the winding shaft 6. The second motor 32 provides driving force for the winding shaft 6 to achieve the purpose of electric winding. On one side of the rotating shaft of the second motor 32, a fixed clamping gear 13 is installed, and electric telescopic rods 14 are arranged on the laminate 20 on both sides of the fixed clamping gear 13. A limiting block 141 is arranged at one end of the electric telescopic rod 14. When the second motor 32 is in the shutdown state, the electric telescopic rod 14 is used to push the limiting block 141 to move to the position of the fixed clamping gear 13 to realize the limiting and locking effect on the fixed clamping gear 13 and prevent it from rotating automatically under the action of gravity. A plurality of card strips 18 are arranged on the outer side of the winding shaft 6. A through hole 8 is opened inside the winding and unwinding turntable 7, and a plurality of card slots 19 are opened on the inner wall of the through hole 8. The card strips 18 are matched and clamped with the card slots 19, so that the winding shaft 6 will not rotate automatically after being inserted into the through hole 8, improving the stability of the winding and unwinding turntable 7. The outer end of the winding shaft 6 is provided with an external thread 26, and the external thread 26 is in threaded connection with the internal thread 23 inside the limiting member 9. The limiting member 9 is arranged on the outer side of the winding and unwinding turntable 7. Through the threaded connection of the limiting member 9, the disassembly and replacement of the winding and unwinding turntable 7 are facilitated.

[0030] Referring to Figures 1-3 , the wire pressing mechanism includes a telescopic sleeve rod 15. The telescopic sleeve rod 15 is a conventional telescopic sleeve rod structure that can move freely. The telescopic sleeve rod 15 penetrates through the upper end of the fixing plate 36, and a spring 16 is sleeved on the outer side of the telescopic sleeve rod 15. A telescopic wire pressing plate 17 is arranged at the bottom of the telescopic sleeve rod 15, and a rotating block 21 is arranged at the upper end of the telescopic sleeve rod 15. After the rotating block 21 rotates, it overlaps with the upper end of the support column 22. Since a groove is arranged at the upper end of the support column 22, after the rotating block 21 is lifted upward and rotated by 90°, it can be placed in the groove at the upper end of the support column 22 to play a role of support and fixation. The support column 22 is arranged at the upper end of the fixing plate 36. Under the action of the elastic force of the spring 16, the telescopic sleeve rod 15 is pushed downward to the surface of the wire on the winding and unwinding turntable 7 to play a role of pressing the wire during the winding and unwinding process and prevent the wire from being messy.

[0031] When the cable winding and unwinding device is in use, first hold the handle 5 by hand and push the device to the working site. Then, the electric push rod 10 is used to push the support plate 11 to support the ground. After stabilization, the winding and unwinding turntable 7 with the cable wire is installed on the winding shaft 6. During the installation process, first unscrew the limiting member 9 and remove it from the outer end of the winding shaft 6. Align the through hole 8 and the card slot 19 inside the winding and unwinding turntable 7 with the winding shaft 6 and the card strip 18. After pushing the winding and unwinding turntable 7 onto the winding shaft 6, then tighten the limiting member 9 onto the winding shaft 6 to complete the fixation. Conversely, the winding and unwinding turntable 7 can be disassembled.

[0032] During operation, when it is necessary to adjust the horizontal angle of the winding and unwinding turntable 7, the first motor 34 is started to drive the gear 25 to transmit power, and then drive the bottom rotating shaft 3 to rotate, thereby driving the bottom plate 31 above the bottom rotating shaft 3 to rotate, so as to achieve the purpose of adjusting the horizontal angle of the winding and unwinding turntable 7 on the bottom plate 31;

[0033] During the process of winding and unwinding the wire, the second motor 32 is started to drive the winding shaft 6 and the winding and unwinding turntable 7 on the winding shaft 6 to rotate, and the cable is wound or unwound during the rotation of the winding and unwinding turntable 7; during this process, the pressing plate 17 above the winding and unwinding turntable 7 is close to the upper surface of the wire, and under the elastic force of the spring 16, the pressing plate 17 is pushed downward to press the wire wound on the winding and unwinding turntable 7. When pressing is not required, the rotating block 21 is lifted upward, and after rotating 90°, the rotating block 21 is placed on the support column 22;

[0034] When the second motor 32 stops operating, the electric telescopic rod 14 pushes the limit block 141 to move to the fixed clamping gear 13 to limit and fix the fixed clamping gear 13 to prevent the fixed clamping gear 13 and the winding shaft 6 from rotating self - rotatably.

[0035] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
