The invention discloses a flaw detection device which is characterized in that a translation plate is movably mounted on a bearing frame, and the bearing frame is movably mounted on a mounting frame.One end of the transverse adjusting mechanism is installed on the bearing frame, and the other end of the transverse adjusting mechanism is connected to the translation plate. The flaw detection sensor is installed on the sensor installation unit, the sensor installation unit is installed on the translation plate in a suspended mode, and centering adjustment of the flaw detection sensor is achieved through the transverse adjusting mechanism. One end of the first lifting mechanism is mounted on the translation plate, and the other end of the first lifting mechanism is connected to the sensor mounting unit. The rail leaning wheel is installed on the rail leaning wheel installation unit, the rail leaning wheel installation unit is installed on the translation plate in a hanging mode, and theflaw detection sensors are installed on the two sides of the rail leaning wheel in a hanging mode. One end of the second lifting mechanism is mounted on the translation plate, and the other end of thesecond lifting mechanism is connected to the rail wheel mounting unit. The technical problem that an existing flaw detection device cannot accurately and positively press the center of the steel rail, the flaw detection bottom wave loss phenomenon is likely to happen, and therefore the detection effect is poor can be solved.
