Problems solved by technology

[0002] Rail bottom flaw detection is of great significance to the safety of rail transportation. Before the formal flaw detection operation on the rail bottom, it is necessary to adjust the flaw detection structure horizontally and vertically to ensure that the flaw detection structure is in a proper position relative to the rail. The existing flaw detection device adjustment It is cumbersome, low in efficiency, and the effect is not good; secondly, in the process of flaw detection operation, the lateral shaking of the flaw detection trolley will also affect the smooth flaw detection of the flaw detection structure on the rail; The wear condition of the trolley is also different, so there will be some ups and downs when the trolley is moving forward, which seriously affects the flaw detection of the flaw detection structure on the rail, cannot guarantee the final flaw detection quality, and seriously affects the safety of rail transportation.

Abstract

The invention relates to the technical field of on active service steel rail flaw detection, and discloses an ultrasonic flaw detection device for a steel rail base metal rail flange. The device comprises a trolley and a flaw detection structure. Rail wheels are arranged at the front and back ends of the bottom of the trolley. The rail wheels are supporting rolling wheels on the steel rail treading face of the trolley. The device further comprises a clamping mechanism. The clamping mechanism is arranged on a transverse beam of the bottom of the trolley and can longitudinally slide and adjust relative to the transverse beam. The clamping mechanism comprises a transverse adjusting bolt. The flaw detection structure is connected to the lower portion of the clamping mechanism through the transverse adjusting bolt, and the transverse adjusting bolt can adjust the flaw detection structure to move transversely. The device is convenient to install and operate, convenient to adjust, high in efficiency, good in effect, stable and reliable in working and small in external disturbance.
