Tension testing device of heat insulation cable for electric power control

Abstract

The invention relates to the technical field of cable production equipment, and discloses a tension testing device of a heat insulation cable for electric power control. The device comprises a bottom plate, a first L-shaped plate and a first clamping seat are fixedly arranged on the left side of the upper surface of the bottom plate, the first clamping seat is arranged on the right side of the first L-shaped plate, two first clamping grooves are symmetrically formed in the upper surface of the first clamping seat, a fixing block is fixedly arranged on the right side of the upper surface of the bottom plate, an air cylinder is fixedly arranged on the upper surface of the fixing block, a mounting plate is fixedly connected with the output end of the air cylinder, a pressure sensor is fixedly arranged on the right side of the mounting plate, a second clamping seat is arranged on the right side of the upper surface of the bottom plate, the second clamping seat is arranged on the right side of the air cylinder, and a second clamping groove is formed in the upper surface of the second clamping seat. According to the tension testing device of the heat insulation cable for electric power control, two ends of the cable can be synchronously clamped, and the two ends of the cable are effectively prevented from falling off when a tension test is carried out.

Description

technical field [0001] The invention relates to the technical field of cable production equipment, in particular to a tension test device for heat-insulated cables for electric control. Background technique [0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires, usually a rope-like cable twisted by one or several groups of wires, each group of wires is insulated from each other, and often It is twisted around a center, and the entire outer surface is covered with a highly insulating covering layer. The pull-out resistance of the cable is an important performance of the cable, which directly affects the life and safety of the cable. [0003] Among them, the patent number is CN111811958A, which discloses a cable tension test device for heat-insulated power control cables, including a frame, cable end fixing tooling, wire clips, tension test devices, cable temperature control devices, and cable temperature ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a tensile test device for heat-insulated cables for power control, which can clamp both ends of the cable synchronously, and can effectively avoid the tension of the two ends of the cable during the tensile test. The advantage of falling off solves the problem that the two ends of the cable cannot be clamped at the same time in the prior art, ensuring the accuracy of the test results
