Abstract

The invention discloses a wear tester for electric power fittings, comprising a frame and a load carrier arranged on the frame; the upper end of the load carrier is connected with a first hanging rope which runs through a pulley set hung at the top of the frame and is then connected with an upper hanging device, a lower hanging device corresponds to the upper hanging device, the lower hanging device is connected with a rocking device, the rocking device is also connected with a power unit, the load carrier comprises a spring mechanism, a winding mechanism and a vibration exciter, the upper end of the spring mechanism is connected with the other end of the first hanging rope, the lower end of the spring mechanism is connected with the winding mechanism, the vibration exciter is also arranged on the spring mechanism, and the vibration exciter applies dynamic load to the spring mechanism. The loader carrier that considers both dead load and simple harmonic load is used provided to simulate load of an electric power fitting in actual engineering application, such that wear results of the tester are more precise and more practical.

Description

technical field [0001] The invention relates to a detection device for electric fittings, in particular to a wear testing machine for electric fittings. Background technique [0002] In the actual project of wind resistance of transmission towers, in order to study the wear of the connecting hardware in the transmission tower line, a variety of wear testing machines have been developed and adopted, but the loaders of most wear testing machines can only apply static loads, which are more suitable. Dynamic loads in the form of actual loads, such as wind loads. The wind load can be simplified as a simple harmonic dynamic load. The simple harmonic dynamic load produces a continuously changing tensile stress on the electric fittings. The changing tensile stress is more destructive to the electric fittings, aggravates the wear of the electric fittings, and further shortens the life of the fittings. , so the wear test results of the wear testing machine in the prior art are not ac...
