Description

Technical Field

[0001] The present application relates to the technical field of track gauge detection, and in particular to an electronic track gauge detector. Background Art

[0002] The track gauge is a special measuring instrument used to measure the gauge between two rails on a railway line. In railway maintenance and inspection, the track gauge is often used to measure the track spacing and superelevation data of railway tracks. Since the track gauge is inevitably bumped and hit during field use and transportation, it is easy to increase the error of the track gauge indication, thereby affecting the accuracy of the measurement data. Therefore, it is necessary to use a track gauge calibrator to calibrate the track gauge.

[0003] In the related art, during the calibration process of the track gauge calibrator, it is often necessary to use a standard block to lift one end of the track gauge to perform superelevation detection of the track gauge. This superelevation detection method requires the inspectors to frequently lift the track gauge and replace standard blocks of different heights when performing detections at different heights, thereby increasing the labor intensity of the inspectors and reducing the detection efficiency. Therefore, we propose an electronic track gauge calibrator to solve the above problem. Utility Model Content
