AI Technical Summary

Technical Problem

The prior art is difficult to effectively detect the profile changes of railway switches, and traditional profile rulers are prone to offset during detection, making it difficult to accurately measure the disease of switches.

Method used

A detector for the combined profile of a railway switch is designed, including the installation housing, detection assembly and magnetic suction assembly. The detection component performs profile measurement by measuring the main body, encoder group and test contact arm. The magnetic suction component uses the force between the permanent magnet and the rail to fix the position of the detector to ensure the accuracy and stability of the detection.

Benefits of technology

It realizes accurate measurement of the railway switch profile structure, ensures the accuracy and stability of the detection results, can adapt to rail structures of various shapes, and improves the versatility and scope of application of the detector.
