Problems solved by technology
In the project, there was a phenomenon that the mesh sleeve connector was twisted due to the non-rotation of the rotary connector, resulting in serious consequences for running the line
Therefore, the detection of the rotation performance of the rotary connector under stress should be used as an important detection index. However, due to the lack of scientific detection methods, the detection of the rotation performance of the rotary connector is often ignored in the test.
In addition, the test tensile load of the rotary connector under stress is relatively large, especially for the old rotary connector after use, there is a safety risk for testers

Description
technical field [0001] The invention relates to the technical field of testing rotary connectors, in particular to a pull torque combined measuring device suitable for rotary connectors. Background technique [0002] At present, the rotary connector is a commonly used tool in the construction of the transmission line project. Due to the harsh environment of engineering construction and transportation and storage, the frictional resistance of the rotary connector increases under stress, and it loses its ability to rotate, and loses its ability to eliminate wires. The effect of turning torque. In the project, there was a phenomenon that the mesh sleeve connector was twisted due to the non-rotation of the rotary connector, resulting in serious consequences for running the line. Therefore, the detection of the rotational performance of the rotary connector under stress should be used as an important detection index. However, due to the lack of scientific detection methods, the ...
