Description

Technical Field

[0001] The utility model relates to the technical field of cable testing equipment, in particular to a spring type cable testing equipment. Background Art

[0002] In order to ensure that the cables meet the requirements of safety, reliability and efficiency during manufacturing, installation and operation, a series of tests need to be carried out on the produced cables, that is, cable testing requires quality inspection, insulation condition assessment and line performance verification of the cables;

[0003] Among the many types of cables, when testing spring-type cables, due to the tensile properties of their structure, a tensile test is required to be performed on the cables. This test can directly reflect the strength of the cables when subjected to tension, ensuring that the cables can withstand the expected tension without breaking in actual use. The recovery test evaluates the ability of the cables to return to their original state after being subjected to force, ensuring that the cables can maintain good working conditions after frequent use. Therefore, some existing tensile test equipment for spring-type cables uses a motor in conjunction with a translational guide mechanism to perform a reciprocating tensile test on the spring-type cables. As a result, the motor needs to frequently rotate forward and reverse, and the motor consumes a certain amount of energy during the frequent forward and reverse rotations, which causes the internal temperature of the motor to rise. Long-term high temperature conditions may affect the life of the motor, which in turn causes the electrical performance of the motor to deteriorate due to high temperature and mechanical wear, and is prone to problems such as increased winding resistance and reduced inductance, thereby reducing the service life of the test equipment.
