[0025] Among them, the base 1 is a structural basis of a wire joint strength test tensile device, and other structures on the wire joint strength test tensile device are directly or indirectly mounted on the base 1. The pair of tensile frames 2 is a structural basis of the cross frame 3 and the tensile drive 4, the joint connecting assembly is used to connect the joint 8 and connect the tensile drive 4, the wire connecting assembly is used to connect the plurality of wires 9 and connect the base 1, the tensile drive 4 outputs the pulling force, and the joint connecting assembly and the wire connecting assembly are used to fix the wire joint to realize the tensile test of the wire joint.

[0026] Specifically, in the process of tensile test of the wire joint, the plurality of wires 9 are connected through the wire connecting assembly, and then any joint 8 in the plurality of wires 9 is connected through the joint connecting assembly. After ensuring the stability of the connection structure, the tensile drive 4 outputs the tensile force to perform the tensile test on the wire joint. The plurality of wires 9 are connected through the wire connecting assembly, so that after the test of a wire 9 and a joint 8 is completed, the test can be restarted by replacing the joint 8 of another wire 9, without disassembling and replacing the wire 9, thereby improving the test efficiency and reducing the labor cost.

[0027] In detail, the tension drive 4 is a hydraulic cylinder, and the base 1 is also connected to a hydraulic station and control panel for controlling the tensile test process. During the tensile strength test, to ensure that the tensile strength of the wire 9 is greater than 1.2-1.5 times the standard tensile strength, and because some wires 9 may have an angle with the tensile direction, a larger pass tensile strength is set to ensure that all pass wires 9 have a tensile strength greater than the standard tensile strength, thus avoiding safety hazards.
