The invention discloses a sliding shoe type steel rail tread detection magnetic flux leakage probe and a working method thereof. The sliding shoe type steel rail tread detection magnetic flux leakage probe comprises a pure ferromagnetic yoke structure, a sliding shoe device and a bearing structure, the pure ferromagnetic yoke structure comprises a magnetizer substructure and a magnetic yoke substructure; the magnetizer substructure is fixed on the sliding shoe device and is used for conducting a magnetizing field generated by the magnetic yoke substructure to the steel rail to magnetize the detected steel rail; the magnetic yoke substructure is suspended on a vehicle bearing structure and is used for generating a magnetizing field; the sliding shoe device comprises a magnetism gathering block, a sliding shoe and a sensor; the two ends of the sliding shoe are riveted and implanted with the magnetism gathering blocks, and the sliding shoe is connected with the elastic structure in the pure ferromagnetic yoke structure through one side of each magnetism gathering block, so that the sliding shoe is located below the pure ferromagnetic yoke structure and attached to the surface of the steel rail; the sensor is fixed to the sliding shoe and used for collecting magnetic flux leakage signals of the steel rail. The method can improve the magnetic flux leakage detection precision, and guarantees the safety and reliability of railway detection.
