Document Type and Number:
Japanese Patent JP2023105380
Kind Code:
A
Abstract:
To provide a rail flaw detector and a rail flaw detection system that can detect a flaw of a rail while suppressing generation of a non-detection region.SOLUTION: The rail flaw detector includes: a frame 41; a tire probe 42 supported by the frame 41, the tire probe detecting the presence or absence of a flaw of a rail while being in contact with the rail; and a pair of guide rollers 43 located ahead of the tire probe 42 and behind the tire probe 42, the guide roller being rotatably supported to the frame 41 and rolling on the rail.
