Power cable strength testing machine with modular fixture

Abstract

The invention discloses a power cable strength testing machine with a modular fixture. The power cable strength testing machine with the modular fixture adopts two fixtures to implement tension or compression strength tests; a claw fixture adopts moving claws to slide and fix a cable; a limiting mechanism can swing leftwards or rightwards in a limited manner when the moving claws move, so that the moving claws can be well prevented from moving randomly, firm and stable clamping can be ensured, and the moving claws can be prevented from being folded to jam hands of a user by accident because of mal-operation when being reset; a cable is inserted from the middle part of the disc-shaped structure of a disc fixture; the cable can be clamped and fixed by clamping ring structures layer by layer; the layered structures are restricted by one another without being loosened or displaced; clamping rings can be tightened or released so as to achieve fastening when the arc-shaped wall of an external rotary table is rotated; the rotation stroke is relatively long, so that the cable can be slowly fastened without being damaged, the clamping firmness of the cable can be prevented from being affected by a damaged cable, and thus test data errors can be prevented.

Description

technical field [0001] The invention relates to the field of electric power design, in particular to a power cable strength testing machine with combined fixtures. Background technique [0002] In the field of power design, domestic power departments focus on the research of power transmission equipment and power-related machinery, but these studies often focus on mechanism design, but ignore the most fundamental control of cable quality in power transmission. In the most basic transmission lines, the quality of power cables is uneven, and there is a great potential safety hazard in long-term use. If the power cables are damaged, both the country and social enterprises will suffer certain economic losses, and are more likely to The safety of personnel is endangered, so it is very important to test the quality of power cables. For testing and testing machines, the fixture is a key part of the whole. A good fixture structure can improve the clamping effect of the power cable ...
