Description

Technical Field

[0001] This utility model relates to the field of inspection device technology, and in particular to a cable inspection device for charging pile operation and maintenance. Background Technology

[0002] With the increasing development of charging technology, the use of charging piles is also increasing. During the installation and use of charging piles, internal breakage detection is usually required. Once detected, timely repair and replacement are carried out to avoid subsequent unusability. Since the outer layer of the cable is usually wrapped with insulation or protective layer, the integrity of the internal battery cells cannot be directly observed by the naked eye and usually needs to be checked by a detector.

[0003] An existing cable inspection device for charging pile maintenance (announcement number: CN220561316U) has at least the following drawbacks:

[0004] In the aforementioned patent, a single V-shaped wheel is used to rotate and drive the cable to move. The V-shaped wheel and the clamp work together to clamp and limit the cable. However, there is frictional resistance between the cable and the clamp. The movement between the V-shaped wheel and the cable mainly relies on friction. The thrust and resistance interfere with each other, making it difficult for a single V-shaped wheel to drive the cable to move smoothly. This can easily lead to poor cable movement. Therefore, there is an urgent need for a cable inspection device for charging pile maintenance to solve the above problems. Utility Model Content

This makes it convenient to use and quite practical. Attached Figure Description

[0026] From the above description, it can be seen that the above-described embodiments of this utility model achieve the following technical effects: When the user needs to inspect cables of different diameters using the movable wheel 2, the distance between the movable wheel 2 and the limiting wheel 3 needs to be adjusted so that the V-groove between the movable wheel 2 and the limiting wheel 3 becomes deeper or shallower. Then, by manually rotating the first threaded post 11 under the support of the bearing 12, the first threaded post 11 and the first threaded hole 10 convert the rotational motion into linear motion, thereby causing the connecting frame 9 to move inside the second support hole 13 and push the T-shaped limiting groove 8 and the movable wheel 2 to move laterally. With the hexagonal post 6 supporting the movable wheel 2, the limiting wheel 3 is fixed and cannot move laterally. Thus, the moving movable wheel 2 makes the V-groove between it and the limiting wheel 3 deeper or shallower, thereby making it possible to use cables of different diameters. Then, the cable is placed between the upper and lower movable wheels 2 and the limiting wheel 3, and the second drive motor 23 is started to drive the second threaded post 24 to rotate. The threads on the second threaded post 24... The symmetrical arrangement allows the second threaded post 24 and the second threaded hole 20 to convert rotational motion into linear motion, which in turn causes the two first support plates 4 to move towards each other, clamping the cable through the moving wheel 2 and the limiting wheel 3. Then, the first drive motor 15 is started to drive the gear 16 to rotate, which in turn drives the end gear plate 14 and the hexagonal post 6 to rotate. The rotating hexagonal post 6 drives the moving wheel 2 and the limiting wheel 3 to rotate, thereby moving the clamped cable. The friction between them is increased by the set protrusion 19. At the same time, the detection is performed by the wire clamp 28 and the detector 27 (the detection method is the same as in the reference document, only the problem is introduced, and the existing technology will not be described again). This comprehensively achieves the effect of adjusting the distance between the moving wheel 2 and the limiting wheel 3, so that the moving wheel 2 and the limiting wheel 3 can fully contact the outer sheath of cables of different diameters. The upper and lower clamping method ensures the friction pushing effect. At the same time, the set protrusion 19 increases the friction between the cable and the wire clamp, effectively overcoming the resistance of the wire clamp 28 and avoiding the cable movement being difficult due to insufficient friction wheels. It is convenient to use and quite practical.
