Abstract

The invention belongs to the technical field of railway accessories, and discloses an elastic strip fatigue test device. The test device comprises an elastic strip and an installation body, wherein lugs extending towards a direction far away from the installation body are arranged at one end of the installation body, and rail grooves for embedding the elastic strip are formed at the other end; a pair of lugs and a pair of rail grooves are provided; each lug is an arc structure, and a lower end of each rail groove is an inlet end, and an upper end thereof is a closed end for limiting. Through the test device disclosed by the invention, the elastic strip can be stably installed on the test device, the test precision is ensured, and the vibration condition of the actual working condition canbe well simulated. The invention further discloses a monitoring system for well detecting the test device, thereby guaranteeing the smooth operation of the test process.

Description

technical field [0001] The invention belongs to the technical field of railway accessories, in particular to a spring bar fatigue test device and a monitoring system. Background technique [0002] The railway uses the rail fastener clip system as part of the lower foundation of the railway; the clip can press the rail through its own elastic buckle, provide a certain rigidity and damping for the rail, and provide sufficient buckle pressure. In order to ensure the performance of the clips, all major manufacturers will test the clips, and use the method of sampling inspection to check the quality of the clips produced by fatigue. [0003] In the existing clip fatigue test device, it is actually impossible to keep the clip in a stable position, so when the pressure is applied, the clip is displaced, resulting in low test accuracy. Contents of the invention [0004] In order to solve the above problems, the present invention discloses a spring bar fatigue test device, which c...
