[0002] The cable tension testing machine is a professional equipment for testing the mechanical properties of cables, ropes, steel wire ropes and other materials under tensile load. Its main functions include measuring the tensile strength, breaking strength, elongation, elastic modulus and other parameters of the cable, and evaluating the safety and reliability of the cable in actual application.

[0003] The existing cable tension testing machine generally directly extrudes the surface of the cable through a rigid clamp when clamping the cable, which causes local stress to exceed the standard, especially causing structural damage to synthetic fiber ropes. Moreover, the cable end is only fixed by a single locking mechanism, such as a bolt pressing plate, and the rope head may loosen during stretching, causing the test to be interrupted. Therefore, the cable load-bearing performance detection equipment is proposed. SUMMARY

[0004] The purpose of the present application is to provide a cable load-bearing performance detection equipment to solve the problem of instability of the cable load-bearing performance detection equipment in clamping the cable as described in the background.

[0006] Preferably, the winding extrusion assembly comprises a winding rod fixed in the inner side of the clamp and an extrusion rod arranged in the inner side of the clamp, the inner side of the clamp is symmetrically provided with a connecting groove, and the two sides of the extrusion rod are symmetrically fixed with connecting rods which are in sliding connection with the connecting groove.

[0007] Preferably, the end of the clamp is symmetrically fixed with a pneumatic cylinder, the end of the clamp is symmetrically provided with a through hole, and the end of the pneumatic cylinder is connected with a hydraulic rod which penetrates through the inside of the through hole and is fixedly connected with the extrusion rod.

[0008] Preferably, the bottom end of the extrusion rod is fixed with a semicircular convex texture ring.

[0009] Preferably, the auxiliary clamping assembly comprises a cross buckle fixed at both sides of the clamp and a cross buckle arranged at the end of the cross buckle seat, and one end of the cross buckle is connected with a shaft at one end of the cross buckle seat.

[0010] Preferably, the other end of the cross buckle seat is provided with a tightening piece connected with the cross buckle.

[0011] Preferably, symmetrical support seats are fixed at the bottom corners of the base, and a stable placing mechanism is arranged at the bottom end of the support seat, wherein the stable placing mechanism comprises an anti-skid pad fixed at the bottom end of the support seat.

[0012] Compared with the prior art, the present application has the following beneficial effects:

[0013] Firstly, through the synergistic effect of the winding rod and the extrusion rod, the cable body can uniformly disperse stress during the test process, avoiding the cable crushing or structural damage caused by local extrusion of the traditional clamp; secondly, the semicircular convex ring at the bottom of the extrusion rod imitates the biological tribology structure, not only increases the effective contact area with the surface layer of the cable, but also further reduces the risk of stress concentration through the gradual pressing mode, significantly improves the stability and reliability of clamping; and the cross buckle, shaft and tightening piece in the auxiliary clamping assembly are designed to realize the secondary reinforcement of the cable end, the clamping force can be flexibly adjusted according to the diameter of the cable, effectively preventing the rope head from loosening during the test process, and ensuring the accuracy and continuity of the test data.
