Description
Technical Field
[0001] This utility model belongs to the field of cable technology, specifically relating to an automatic overhead cable retraction and deployment device. Background Technology
[0002] Overhead cables are overhead conductors with insulation and protective sheaths. They are a special type of cable manufactured using a process similar to that of cross-linked cables. They represent a new power transmission method that falls between overhead conductors and underground cables. In the operation of overhead cables, the cables need to be wound up on a cable winding rack.
[0003] Existing cable winding and unwinding devices have difficulty cleaning dust and attached impurities from cables during the winding and unwinding process. Dust and impurities adhering to the surface of the cable affect the winding and unwinding effect and are not aesthetically pleasing. At the same time, it is difficult to automatically correct the winding position of the cable, and the amount of cable wound on the roller is uneven. Utility Model Content
[0004] To address the problems mentioned in the background art, this utility model provides an automatic overhead cable winding and unwinding device, which solves the problems of difficulty in cleaning dust and attached impurities on the cable, difficulty in automatically correcting the cable winding position, and uneven cable winding on the roller.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic overhead cable reeling and unloading device, comprising a worktable and a limiting block. A mounting frame is installed on one side of the worktable surface, and a first motor is installed on one side of the mounting frame surface. The output end of the first motor is connected to a first rotating shaft, and one end of the first rotating shaft is connected to a wire roller. A second motor is installed on one side of the limiting block surface, and the output end of the second motor is connected to a bidirectional threaded rotating shaft. A movable block is threadedly connected to the surface of the bidirectional threaded rotating shaft. A concave connecting block is installed on one side of the movable block surface. Both ends of the inner surface of the concave connecting block are connected to a driven shaft, and one end of the driven shaft is connected to a limiting roller. A mounting plate is fixedly connected to the other side of the movable block surface. A third motor is installed on one side of the mounting plate surface, and the output end of the third motor is connected to a second rotating shaft. One end of the second rotating shaft is connected to a cleaning brush.
[0006] Preferably, the limiting block has a limiting groove inside, and the surface of the limiting groove is slidably connected to the surface of the movable block.
[0007] Preferably, a slide rail is installed on one side of the worktable surface, and the surface of the slide rail is slidably connected to the surface of the limiting block.
[0008] Preferably, a connecting plate is fixedly connected to one side of the top of the workbench, and a servo electric push rod is installed on one side of the surface of the connecting plate, with one end of the servo electric push rod connected to one side of the surface of the limiting block.
[0009] Preferably, each of the four corners of the bottom of the workbench is fixedly connected to a support leg, and the bottom of the support leg is equipped with casters.
[0010] Preferably, a handle is fixedly connected to one side of the inside of the workbench.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The second rotating shaft drives the cleaning brush to continuously clean the dust and attached impurities on the cable surface, making the cable surface cleaner and improving the aesthetics of cable winding and unwinding. Through the cooperation of the servo electric push rod, slide rail, and limit roller, the bidirectional threaded rotating shaft drives the movable block and limit roller to move closer together to restrict the position of the cable, ensuring that the position of the cable does not deviate during the winding process. At the same time, the servo hydraulic cylinder pushes the limit block to move, thereby correcting the winding position and ensuring that the cable is wound more evenly on the roller.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-7 The present invention provides the following technical solution: an automatic overhead cable winding and unwinding device, comprising a workbench 1 and a limiting block 8. A mounting frame 5 is installed on one side of the surface of the workbench 1. A first motor 12 is installed on one side of the surface of the mounting frame 5. The output end of the first motor 12 is connected to a first rotating shaft 10. One end of the first rotating shaft 10 is connected to a wire roller 11. A second motor 16 is installed on one side of the surface of the limiting block 8. The output end of the second motor 16 is connected to a bidirectional threaded rotating shaft 14. A movable block 15 is threadedly connected to the surface of the bidirectional threaded rotating shaft 14. A concave connecting block 17 is installed on one side of the surface of the movable block 15. Both ends of the inner surface of the concave connecting block 17 are connected to a rotating shaft 23. One end of the rotating shaft 23 is connected to a limiting roller 22. A mounting plate 18 is fixedly connected to the other side of the surface of the movable block 15. A third motor 19 is installed on one side of the surface of the mounting plate 18. The output end of the third motor 19 is connected to a second rotating shaft 21. One end of the second rotating shaft 21 is connected to a cleaning brush 20.
[0025] In this embodiment: the first motor 12 drives the wire roller 11 to take in and release the wire, the second motor 16 drives the bidirectional threaded rotating shaft 14 to rotate and adjust the position between the movable blocks 15, and the third motor 19 drives the cleaning brush 20 to rotate and clean the surface of the overhead cable. The motors drive independently and do not interfere with each other, the division of labor is clearer, it is convenient to operate, and the overall reliability is improved.
[0026] In this embodiment: the bidirectional threaded rotating shaft 14 drives the movable block 15 and the limiting roller 22 to move closer or further apart, thereby precisely adjusting the spacing of the limiting roller 22. This can limit cables of different diameters and prevent them from deviating. While the limiting roller 22 positions the cable, the cleaning brush 20 automatically aligns with the cable surface without the need for secondary calibration, thus improving cleaning efficiency.
[0027] In this embodiment: the servo electric push rod 9, in conjunction with the slide rail 7, pushes the limit block 8 to slide in parallel, thereby moving the cable and avoiding uneven winding and unwinding during the cable winding process.
[0028] In this embodiment, the handle 6 allows the operator to easily control the device, conforms to ergonomic design, and is easy to operate.
[0029] In this embodiment: the corresponding support leg 2 can improve the stability of the device, and the caster wheel 3 can make it easy for the staff to push the device to the corresponding position. The caster wheel 3 combined with the handle 6 can make it easy for the staff to move the device to the corresponding position when retracting or extending the cable.
[0030] The working principle and usage process of this utility model are as follows: After installation, the overhead cable to be retracted is passed between the limiting roller 22 and the cleaning brush 20, and the overhead cable is wound around the surface of the roller 11. The second motor 16 is started, which drives the bidirectional threaded rotating shaft 14 to rotate, thereby causing the movable block 15 to move under the restriction of the limiting groove 13. This causes the cleaning brushes 20 and the limiting roller 22 to move closer together. When the surface of the limiting roller 22 is in full contact with the surface of the overhead cable, the second motor 16 is turned off, and two sets of third motors 19 are started respectively, which drive the second rotating shaft 21 to rotate, thereby driving the cleaning brushes 20 to rotate. The continuous rotation of the cleaning brushes 20 removes dust from the surface of the overhead cable. The device is cleaned of impurities. The first motor 12 is started, which drives the first rotating shaft 10 to rotate, thereby driving the wire roller 11 to rotate. The wire roller 11 rotates continuously to wind up and unwind the overhead cable, and moves the subsequent overhead cable. The servo electric push rod 9 is started, which pushes the limit block 8 to move slowly, thereby driving the overhead cable to slide parallel, ensuring that the position of the overhead cable does not deviate during the winding and unwinding process. The movement and direction of the device are controlled by the handle 6 and the universal wheel 3. The first motor 12 controls the wire roller 11 to wind up or lay the overhead cable. All electrical equipment in this device is powered by an external power supply. All motors or electric push rods in this paper are controlled by a PLC control system.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
