Description

Portable flaw detection equipment for track detection Technical Field The application relates to the technical field of rail flaw detection, in particular to portable flaw detection equipment for rail detection. Background In the running process of the train, the rail can have the defects of cracks, slag falling, breakage and the like under the repeated action of the train, the internal defect castings are increased, the breakage is very easy to occur under the action of fatigue stress, and the running safety of the train can be influenced, so that the accuracy of the rail flaw detection work is particularly important. CN216792114U relates to a rail flaw detector with grinding and washing functions, which can effectively remove intractable rust on the surface of the rail, and the water sprayed from the spray head can timely wash away the residual dirt after cleaning, thereby facilitating subsequent ultrasonic detection and improving detection accuracy. When the flaw detector in the scheme is used for carrying out flaw detection operation on a track, the flaw detector is erected on the track, travelling wheels on two sides are in a suspended state, and then the front overturning frame and the rear overturning frame are overturned, so that a probe is positioned at the top of the track, then a worker pushes the flaw detector to support the whole movement by virtue of the front overturning frame and the rear overturning frame, when the condition of large wind force is caused, the flaw detector is easy to shake left and right, the contact between the probe and the track is unstable due to the shake, the detection accuracy is influenced, and in addition, because of the instability of the flaw detector, the worker needs larger force to keep balance and control the flaw detector, and the labor intensity of the worker is increased, so that the light flaw detection equipment for track detection is necessary to solve the problems.
