Description

Movable automatic axle flaw detection device Technical Field The utility model belongs to the technical field of train detection, and particularly relates to a movable automatic axle flaw detection device. Background The wheel axle is a key component for running the railway vehicle, the safety performance of the wheel axle is critical to the normal running of the train, and the wheel axle is usually required to be subjected to flaw detection periodically to ensure the running safety. The inspection of the axle usually adopts an ultrasonic inspection instrument, an operator conveys the instrument to an axle inspection station by using a trolley and the like, then the hand-held instrument approaches and is attached to the axle for inspection, and the operation of manually adding coupling liquid and the like is needed. The method requires personnel to carry out detection operation for a long time, the detection efficiency depends on the proficiency of operators and the working time of the personnel, and the method is in face of railway vehicles with increasingly large scale, and is not only labor-consuming and sharply increased, but also has high efficiency. The prior art Chinese patent CN201610791776.9 discloses an ultrasonic flaw detection scanner for an axle, which comprises a shell, a rotating assembly and a phased array ultrasonic probe, wherein the rotating assembly comprises a driving motor and a rotary table, the driving motor is fixed in the shell through a supporting frame, the rotary table can be rotatably arranged on the shell and is fixedly connected with an output shaft of the driving motor, and the phased array ultrasonic probe is fixed on the rotary table. The ultrasonic flaw detection scanner needs to be held by an operator, and is labor-consuming and low in efficiency. Disclosure of utility model In view of the above, the present utility model provides a mobile automatic axle flaw detector capable of automatically detecting an axle flaw.
