The steel rail flaw detection vehicle comprises a steel rail sound wave flaw detection system and a steel rail weld joint automatic identification system. The steel rail sound wave flaw detection system comprises a wheel detection frame connected to a vehicle body of the steel rail flaw detection vehicle, a primary wave transducer which is arranged on the wheel detection frame, is configured to enable the distance between a first intersection point of a primary wave emitted by the primary wave transducer and a rail jaw of the steel rail and the center line of a tread of the steel rail to be 0.48-0.56 L, and is used for detecting defects of a first part of the steel rail, and a secondary wave transducer which is arranged on the wheel detection frame, is configured to enable the distance between a second intersection point of secondary waves emitted by the secondary wave transducer and a rail jaw of the steel rail and the center line of the tread of the steel rail to be 0.62-0.73 L, andis used for detecting defects of a second part of the steel rail. The steel rail weld joint automatic identification system comprises a sound wave transducer used for detecting a steel rail weld jointand arranged on the wheel detection frame.
