Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and in particular to a cable abrasion resistance testing device. Background Technology

[0002] A cable abrasion resistance testing device is a specialized piece of equipment used to evaluate the abrasion resistance of wires and cables. It simulates friction, scratching, or wear scenarios that may be encountered in actual use to conduct durability tests on the cable's insulation, conductor, and overall structure. Its design typically includes core components such as fixing, friction force application, data monitoring, and automated control to quantify the cable's performance under repeated mechanical stress.

[0003] In the existing technology, some cable abrasion resistance testing devices apply controllable friction, pressure or reciprocating motion to the cable through friction mechanisms (such as abrasive wheels, scraping heads or rotating discs) to simulate the wear of the cable in actual environments (such as passing through holes, forests or frequent movement scenarios). However, some cable abrasion resistance testing devices cannot measure the external appearance of different parts of the cable because the position of the abrasive wheel is fixed. The cable needs to be disassembled and reinstalled, which causes inconvenience to the testers. Utility Model Content

The outside of the fixing plate 15 is fixedly connected to a motor 16. The output end of the motor 16 is fixedly connected to a rotating shaft 17, and the rotating shaft 17 passes through the fixing plate 15. The outside of the rotating shaft 17 is fixedly connected to a friction wheel 18. One end of the rotating shaft 17 is fixedly connected to a counterweight 19. The inside of the square plate 9 is slidably connected to a limiting rod 20, and the limiting rod 20 is fixedly connected to the inside of the protective cabinet 1 for adjusting the position of the friction wheel 18.

[0035] Reference Figure 2 , Figure 4 and Figure 6 The external thread of the bidirectional threaded rod 8 is connected to a lifting plate 21. The internal sliding connection of the lifting plate 21 is to the outside of the limiting rod 20. Multiple tension rods 22 are fixedly connected to the top of the lifting plate 21 for adjusting the position of the lifting plate 21. The internal fixed connection of the protective cabinet 1 is to a support plate 23.

One end of the handle 26 is fixedly connected to a bidirectional threaded rod 27 for driving the bidirectional threaded rod 27 to rotate.

[0036] Reference Figure 6 , Figure 7 The external thread of the bidirectional threaded rod 27 is connected to a receiving plate 28. The external fixed connection of the receiving plate 28 is a disc 29.

[0037] Working principle: Hold handle 36 to open transparent door window 35 via hinge 34, place cable 24 on support plate 23, with both ends of cable 24 passing through protective cabinet 1, then hold handle 26 and rotate it, causing bidirectional threaded rod 27 to rotate, causing two receiving plates 28 to move towards each other, causing disc 29 to move, thereby adjusting the position of rotating rod 30, then hold rotating rod 30 and rotate it, causing multiple moving plates 32 to move towards each other, causing clamping blocks 33 to move closer to each other, thereby clamping cables 24 of different sizes.

[0038] Then, start motor 3 to drive rotating shaft 4 to rotate, which in turn drives rotating wheel 6 to rotate. Through belt 7, rotating wheel 6 and another rotating shaft 4 rotate, which in turn drives two bidirectional threaded rods 8 to rotate, allowing square plate 9 to move along limiting rod 20. Then, start cylinder 11 to drive telescopic rod 12 to extend and retract, which drives receiving plate 13 to move, allowing receiving plate 13 to drive square slider 14 to slide along slide groove 10. Adjust the position of friction wheel 18 so that friction wheel 18 is aligned with the part of cable 24 to be tested. Start motor 2 16 to drive rotating shaft 17 to rotate, which in turn drives friction wheel 18 to rotate, rubbing cable 24 to achieve the effect of polishing cable 24. At the same time, counterweight 19 can keep the weight at both ends of rotating shaft 17 consistent, ensuring that friction wheel 18 rotates consistently and avoiding errors. The testing personnel can observe the situation of protective cabinet 1 through transparent door and window 35.

[0039] When the bidirectional threaded rod 8 rotates, it also drives the lifting plate 21 to move towards the limiting rod 20 and the square plate 9, causing the tension rod 22 to rise, bringing it closer to the cable 24 and continuing to rise until the cable 24 is close to the friction wheel 18, providing tension to the cable 24 and ensuring that the friction between the cable 24 and the friction wheel 18 can proceed smoothly. Then, the surface wear, scraping force, number of times, and other parameters before and after friction are recorded using a spectrophotometer or sensor. Combined with the control system, the wear resistance index is calculated. Finally, the cable outer insulation layer damage and conductivity stability are detected by an insulation resistance tester, combustion performance test equipment, or damp heat test chamber.
