Line vibration fatigue damage detection device

Abstract

The invention relates to the technical field of cable strength testing, in particular to a line vibration fatigue damage detection device which is characterized in that a supporting frame is arranged on the upper end face of a workbench, positioning cylinders are rotationally connected to the two sides of the supporting frame, clamping rods are arranged on the side walls of the positioning cylinders, threads are formed in the outer sides of the clamping rods, and the positioning cylinders are rotationally connected with the supporting frame. The clamping rod is in threaded connection with the positioning cylinder, a clamping protrusion is arranged at the top of the clamping rod, a positioning plate is arranged above the workbench, a tensile machine is arranged on the upper end face of the positioning plate, a drag hook is arranged at the output end of the tensile machine, and a conveying mechanism for driving the positioning plate to move is arranged on the workbench. And a driving part for driving the positioning cylinder to rotate is arranged on the supporting frame. Compared with the prior art, the tensile strength and the torsional strength of the cable can be detected respectively, the torsional strength can be detected while the tensile strength of the cable is detected, equipment does not need to be replaced, and the detection efficiency is improved.
