The invention discloses a flaw detection device, which is characterized in that a bearing frame is arranged on a mounting frame, and a translation plate is movably mounted on the bearing frame. One end of the transverse adjusting mechanism is installed on the bearing frame, the other end of the transverse adjusting mechanism is connected to the translation plate, and the translation plate can transversely move on the bearing frame under pushing of the transverse adjusting mechanism. The flaw detection sensor is installed on the sensor installation unit, and the sensor installation unit is suspended on the translation plate. One end of the lifting mechanism is mounted on the translation plate; and the other end of the lifting mechanism is connected to the sensor mounting unit. One end of the inclination angle adjusting mechanism is connected with the bearing frame, and the other end of the inclination angle adjusting mechanism is connected to the mounting frame.The included angle between the bearing frame and the steel rail horizontal plane is adjusted through stretching of the inclination angle adjusting mechanism. Centering adjustment of the flaw detection sensor is achieved through the transverse adjusting mechanism, and lifting and pressing of the flaw detection sensor are achieved through the lifting mechanism. The technical problems that an existing flaw detection device cannot adjust the angle between the detection wheel and the cross section of the steel rail and cannot adapt to rail bottom slope changes of different line rails can be solved.
