Automatic adjusting device for sliding shoe type probe for steel rail flaw detection

The invention relates to a steel rail flaw detection technology, aims to solve the problem that ultrasonic detection precision is reduced due to the fact that an ultrasonic probe deviates from the center of a steel rail in the steel rail flaw detection process, and particularly relates to a steel rail flaw detection sliding shoe type probe automatic adjusting device which comprises a vehicle body fixing table, an operation computer and a mainframe box. According to the steel rail flaw detection equipment disclosed by the invention, the situation that the detection precision of the steel rail flaw detection equipment is reduced due to position deviation is avoided by supporting the centering connecting rod through the two steel rail flaw detection equipment which are connected into a whole; an ultrasonic detector in the outer support can adjust whether the position of an ultrasonic probe deviates or not through a signal sent by the ultrasonic probe, so that the flaw detection data of the steel rail flaw detect
