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...
