Railway track flaw detection mechanism and flaw detection vehicle

Abstract

The invention relates to the technical field of rail flaw detection, and discloses a railway rail flaw detection mechanism and a flaw detection vehicle, the railway rail flaw detection mechanism comprises a fixing frame, a guide wheel and a flaw detection wheel, and also comprises a longitudinal adjusting frame, a transverse adjusting frame and a flaw detection wheel frame; the longitudinal adjusting frame is installed on the fixing frame in a longitudinal sliding mode. The transverse adjusting frame and the flaw detection wheel frame are mounted on the longitudinal adjusting frame in a transverse sliding manner; a guide wheel is mounted on the transverse adjusting frame; flaw detection wheels are mounted on the flaw detection wheel carriers, are opposite to the wheel edges of the guide wheels and are arranged along a pre-detected track; the railway track flaw detection mechanism is simple in structure and convenient to operate, the wheel edge of the flaw detection wheel makes close contact with the track surface of the track to be detected in the flaw detection process, a good centering state is kept, the flaw detection accuracy is ensured, and the flaw detection efficiency of a flaw detection vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of rail flaw detection, in particular to a railway rail flaw detection mechanism and a flaw detection vehicle. Background technique [0002] The rail is the main component of the railway track. Its function is to guide the wheels of the rolling stock, bear the huge pressure of the wheels, and transmit it to the sleeper. The rails must provide the wheels with a continuous, smooth and least drag rolling surface. Therefore, in order to ensure the safe operation of the locomotive, the railway system needs to conduct flaw detection on the rails frequently to detect fatigue defects and welding defects in the rail head and rail waist range (including near the joints). [0003] At present, artificial detection equipment or detection vehicles are widely used for flaw detection of railway tracks. [0004] Manual detection equipment is convenient for manual operation to detect faults on railway tracks, but the operat...
