Description

Technical Field

[0001] This utility model belongs to the field of cable abrasion resistance testing technology, specifically relating to a cable sheath abrasion fatigue testing device. Background Technology

[0002] As the first line of defense for cables, the abrasion resistance of cable sheaths not only determines the cable's service life but also directly affects its reliability and safety in harsh environments. Therefore, cables need to undergo abrasion fatigue testing on their sheaths using testing equipment before leaving the factory. This type of cable sheath abrasion fatigue testing equipment is a common type of grinding testing equipment. For example, the existing patent with publication number CN106198283A discloses "a wire abrasion testing device, including a worktable, a grinding table on the worktable, a grinding groove in the middle of the grinding table for placing the wire, pulleys on both sides of the grinding groove to drive the rotation of the wire, a support above the grinding table, and a grinding plate controlled by a cylinder for lifting and lowering on the support." It can be seen that the application describes a common type of cable sheath abrasion fatigue testing equipment, which can achieve abrasion fatigue testing of the cable sheath through the rotation of the grinding wheel.

[0003] In practical use, existing cable sheath wear fatigue testing equipment requires placing the cable on the test platform. However, the existing testing equipment lacks a structure that can quickly and stably limit the cable's position, resulting in the cable's inability to maintain its stability during testing, which is a drawback. Although existing technologies can use screw clamping to clamp and limit the cable, this method is not very convenient and cannot achieve rapid cable handling. Furthermore, excessive clamping can easily cause compressive damage to the cable surface. Therefore, this invention aims to improve the existing cable sheath wear fatigue testing equipment.
