The invention provides a rail flaw detection car detection wheel guiding device which comprises a fixing base, a mounting support, a flaw detection wheel set, a telescopic piece and a connecting rod, the fixing base is rotationally connected with the mounting support, and the flaw detection wheel set is arranged below the mounting support in a sliding mode; the sliding direction of the flaw detection wheel set is perpendicular to the rotating axis between the fixing base and the mounting support, the middle of the connecting rod is rotationally connected with the mounting support, the lower end of the connecting rod is movably connected with the flaw detection wheel set, the upper end of the connecting rod is rotationally connected with one end of the telescopic piece, and the other end of the telescopic piece is rotationally connected with the fixing base. According to the detection wheel guiding device, the guiding wheels in the flaw detection wheel set are adopted for guiding and positioning, and the positioning detection precision is improved; wherein the release of the guide wheel and the lifting of the mounting bracket and the flaw detection wheel set can be completed through one action of the telescopic piece, so that the detection wheel can be conveniently lifted and lowered; the detection wheel guiding device can reduce abrasion of the detection wheel and prolong the service life.
Description
technical field [0001] The invention relates to the technical field of rail flaw detection, in particular to a detection wheel guide device for a rail flaw detection vehicle. Background technique [0002] With the continuous advancement of urbanization, the population converges to the city, causing urban traffic congestion. The subway plays an important role in solving problems such as urban roads due to its advantages of large carrying capacity, fast speed and no ground space. Among them, the rail, as the running track of the train, plays an important role in the whole system, and ensuring that the rail is in a non-destructive state at all times is of great significance to the safe operation of the train. [0003] The Chinese patent with the application number CN201911011903.9 discloses a probe wheel bracket for an ultrasonic flaw detector of a steel rail. The solution is to set a polyurethane wheel with rims before and after the probe wheel for positioning. It is installe...
