Description

Technical Field

[0001] This utility model relates to the field of cable winding and unwinding technology, and in particular to a cable winding and unwinding device for power engineering. Background Technology

[0002] In the construction and operation of power engineering projects, the transportation, laying, and retraction of cables are essential and crucial steps. To improve cable laying efficiency and ensure construction safety, specialized cable retraction devices are typically used to assist in the operation. These devices are widely used in power line erection, underground cable laying, and maintenance sites, effectively improving cable laying efficiency, reducing manual labor, and enhancing control stability and safety during operation.

[0003] Existing cable winding and unwinding devices primarily use mechanical support structures to support the cable rollers. The cable rollers are manually moved onto the device, and then a rotating shaft or rollers drive the cable to wind or unwind. The support structure mostly uses fixed or adjustable brackets in conjunction with rotating shaft assemblies to install and rotate the cable rollers. Typically, the cable rollers need to be manually lifted and placed on the brackets. During the cable winding and unwinding process, the orderly release and retrieval of the cable is achieved either by a motor driving the drum or through manual operation.

[0004] However, in the existing technology, cable rollers are generally large in size and heavy in weight. Under the complex conditions of the construction site, it is difficult to manually move the cable rollers to the cable take-up and release device. In particular, the installation process often requires the cooperation of multiple people, which can easily lead to problems such as unstable handling, inaccurate positioning or equipment damage. This results in reduced wiring efficiency, inconvenience in operation, and limits the flexibility of the cable take-up and release device in the field. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cable winding and unwinding device for power engineering, including a base, a bracket fixedly connected to the top of the base, a cone fixedly connected to one side of the bracket, and a support component provided on the top of the base;

[0007] The support assembly includes a second bracket, the outer wall of which is fixedly connected to the top of the base. A first limiting plate is slidably connected inside the second bracket.

A limiting groove is formed inside the first limiting plate, and the first limiting plate is slidably connected to the outer wall of the limiting block through the limiting groove.

[0012] As a further description of the above technical solution:

[0013] The base is fixedly connected to the top of a housing, and a rotating shaft is rotatably connected inside the housing.

[0014] As a further description of the above technical solution:

[0015] A support rod is rotatably connected to the outer wall of the shaft, and an anti-slip strip is fixedly connected to one side of the support rod.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, firstly, the second cone cylinder slides on the outer wall of the limiting block through the limiting groove on the first limiting plate to prevent the second cone cylinder from rotating with the threaded rod. Then, the second cone cylinder extends out of the second bracket and embeds into the cable roller, so that the conical surface of the outer wall of the second cone cylinder is embedded and supports the cable roller, which achieves the effect of facilitating the installation of the cable roller, solves the problem that the cable roller is heavy and it is inconvenient to move it to the take-up and put-down rack, and improves the convenience of the cable take-up and put-down device.

[0024] 2. In this utility model, the support rod and the cable are prevented from slipping by anti-slip strips.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3The present invention provides an embodiment of a cable winding and unwinding device for power engineering, comprising a base 1, which serves as the load-bearing and stabilizing structure of the entire device and provides a stable support platform. A bracket 2 is fixedly connected to the top of the base 1, which is used to fix and install a cone 3. A cone 3 is fixedly connected to one side of the bracket 2, which is used to insert one end of the cable roller and provide a rotation fulcrum for the cable roller. A support component is provided on the top of the base 1 to assist in supporting and adjusting the installation and positioning of the other end of the cable roller.

[0033] The support assembly includes bracket 2 (4), whose outer wall is fixedly connected to the top of base 1 to form a three-dimensional support structure and provide an installation cavity for subsequent limiting and lifting structures. A limiting plate 1 (6) is slidably connected inside bracket 2 (4). Limiting plate 1 (6) serves as a support component for cone cylinder 2 (7), used to move vertically to adjust the height of cone cylinder 2 (7). Cone cylinder 2 (7) is fixedly connected to one side of limiting plate 1 (6), serving as a tapered positioning component at the other end of the cable insertion roller, working in conjunction with cone cylinder 1 (3) to fix and support the cable roller. A limiting assembly is provided inside bracket 2 (4) for limiting... The sliding direction and stroke of the limiting plate 6 are controlled to ensure stable operation under vertical force. A threaded rod 10 is internally threaded to the bracket 4. The threaded rod 10 rotates to raise and lower the limiting plate 6, thereby achieving precise height adjustment of the cone 7 to accommodate the installation requirements of different specifications of cable rollers. One end of the threaded rod 10 is fixedly connected to a limiting plate 11, which restricts the axial sliding of the threaded rod 10, improving the reliability of the transmission structure. The limiting plate 11 is rotatably connected inside the cone 7 to synchronously transmit rotational motion to the cone 7 and control its angle. The bracket 24 has a drive assembly at one end to drive the threaded rod 10 to rotate, achieving automatic lifting. The drive assembly includes a motor 8, which provides a stable driving force to rotate the threaded rod 10. The output end of the motor 8 is connected to one end of the threaded rod 10, improving structural compactness and transmission efficiency through direct transmission. A telescopic rod 19 is fixedly connected to the outer wall of the motor 8. The telescopic rod 19 is used to stabilize the connection between the motor 8 and the bracket 24, improving the support rigidity and operational stability of the entire drive system. One end of the telescopic rod 19 is fixedly connected to the bracket 24. At one end, further limiting support is provided for the installation position of the motor 8. The limiting component includes a limiting block 5. One side of the limiting block 5 is fixedly connected to the inner wall of the bracket 2 4 to provide a sliding guide rail and limiting function, preventing the limiting plate 1 6 from moving in an unexpected direction and ensuring the safety and stability of the lifting process. The limiting plate 1 6 has a limiting groove 12 inside. The limiting groove 12 is used to cooperate with the limiting block 5 to form a sliding guide structure. The limiting plate 1 6 is slidably connected to the outer wall of the limiting block 5 through the limiting groove 12 to ensure that it slides linearly within the fixed track, thereby realizing reliable guiding control for lifting adjustment.

[0034] Reference Figure 4A housing 13 is fixedly connected to the top of the base 1. The housing 13 serves as a support structure to cover and protect the internal moving components, enhancing the overall stability and protective performance. A rotating shaft 14 is rotatably connected inside the housing 13, acting as a drive fulcrum and rotating around its axis to cause the support rod 15 to swing, adapting to different cable support angles. The support rod 15 is rotatably connected to the outer wall of the rotating shaft 14. The support rod 15 is used to contact and support the cable, possessing good mechanical strength to withstand the cable's weight. An anti-slip strip 16 is fixedly connected to one side of the support rod 15, increasing the friction between the support rod 15 and the cable to prevent slippage or misalignment during placement, thus improving the device's stability. A connecting block 18 is rotatably connected inside the support rod 15, serving as a connection between the support rod 15 and the telescopic component. It has rotational adjustment capabilities, used to coordinate with the telescopic structure for angle adjustment. A telescopic rod 19 is fixedly connected to one side of the connecting block 18. The telescopic rod 19 provides retractable support, enabling the support rod 15 to elastically deform under support, thus improving its adaptability to dynamic changes in the cable. One end of the telescopic rod 19 is fixedly connected to a connecting block 17, which serves as a rotating connection point between the telescopic rod and the housing 13. This allows the telescopic rod to adjust its direction with structural movement, maintaining a reasonable force path. The connecting block 17 is rotatably connected inside the housing 13, improving the flexibility and stability of the structure through rotational connection and preventing jamming between moving parts. A spring 20 is fitted on the outer wall of the telescopic rod 19, providing continuous elastic support for the telescopic structure and having a vibration-absorbing and buffering effect. One end of the spring 20 is fixedly connected to one side of the connecting block 17, providing a fixed fulcrum to maintain the initial state of the spring 20. The other end of the spring 20 is fixedly connected to one side of the connecting block 18, limiting the rebound and movement direction of the support rod 15 through elastic action, thereby achieving the limiting function of unidirectional cable movement.

[0035] Working principle: When using this power engineering cable winding and unwinding device, firstly, when installing the cable roller, move the cable roller to align the holes on both sides of the base 1 with the cone cylinder 3 and the cone cylinder 7. Then, the output end of the motor 8 drives the threaded rod 10 to rotate. Since the threaded rod 10 is threadedly connected inside the bracket 4, the motor 8 moves with the threaded rod 10 through the limit of the telescopic rod 9. The threaded rod 10 is limited inside the cone cylinder 7 by the limit plate 11. The cone cylinder 7 slides on the outer wall of the limit block 5 through the limit groove 12 on the limit plate 6 to prevent the cone cylinder 7 from rotating with the threaded rod 10. Then, the cone cylinder 7 extends out of the bracket 4 and embeds into the cable roller, so that the conical surface of the outer wall of the cone cylinder 7 is embedded and supports the cable roller, thus achieving the effect of facilitating the installation of the cable roller.

[0036] When the cable is restricted, the cable passes through the housing 13 and contacts the outer wall of the cable through the support rod 15 inside the housing 13. The support rod 15 and the cable are prevented from slipping by the anti-slip strip 16. At the same time, one end of the support rod 15 is supported by the tension of the spring 20, so that the cable can only move in one direction. The spring 20 is restricted by the telescopic rod 19. The two ends are connected and restricted by the connecting block 17 and the connecting block 28, thus achieving the effect of restricting the cable.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
