Calibration device of profile detection system and working method thereof

Abstract

The embodiment of the invention provides a calibration device of a profile detection system and a working method thereof, and the device comprises a bearing module which is installed on a steel rail;a fixed module of a fine movement platform, fixed on the bearing module, and the sliding module of the fine movement platform being connected with the calibration module; a calibration module, comprising at least three calibration surfaces which are parallel to one another and are arranged at equal intervals, the parallel directions of the calibration surfaces being perpendicular to the extendingdirection of the steel rail, the planes of the calibration surfaces being parallel to the top surface of the steel rail, and the thicknesses of the calibration surfaces being sequentially decreased progressively in an equal-difference mode in the direction away from the bearing module; a micrometer head, fixed on the fixed module of the fine moving platform, and a screw rod of the micrometer headbeing connected with the sliding module; a calibration calculation module, correspondingly acquiring measurement data of the steel rail profile detection system and calculating a difference value between the measurement data and preset standard data when laser rays of the steel rail profile detection system sequentially fall on each calibration surface. According to the scheme, the steel rail profile detection system can be calibrated under the installation state of the steel rail profile detection system.

Description

Technical field [0001] The invention relates to the technical field of track detection, in particular to a calibration device of a profile detection system and a working method thereof. Background technique [0002] The contour information of the wheel-rail contact surface and the track geometric state are important indicators for the safe operation of the railway. Obtaining accurate rail profile detection data under high-speed dynamic conditions is an important issue for rail maintenance and repair. At present, my country's railway rail profile detection mainly uses laser camera technology, which is complete and clear through camera imaging, image refinement and image binarization. The contour image to obtain an accurate contour value. Gauge is an important parameter for track geometry dynamic detection. Exceeding the gauge has a serious impact on driving safety. If the gauge is too small, it will increase the wear of wheel flanges and rails. If the gauge is too large, the train...
