The invention provides a probe array for an on-line dynamic train wheel set flaw detection device. The probe array is arranged between a carrying rail and a guard rail of a train forward direction detection area, and comprises a large-angle inclined probe array and a double-crystal straight probe array, wherein the large-angle inclined probe array consists of large-angle inclined probes; the double-crystal straight probe array consists of double-crystal straight probes. By arranging offset probes in the large-angle inclined probe array and distributing the probes in the double-crystal straight probe array in the direction parallel to the track direction in a staggered manner, the probe array can be subjected to crossed overlapped detection, so that the complete coverage detection of the whole wheel is effectively realized, the detectability of different types of defects at a same position is improved, and the detection accuracy and the detection efficiency are improved. Meanwhile, the probe array has the characteristics of simple structure and convenience in use, and is suitable for popularization and application.
Description
technical field [0001] The invention relates to the technical field of flaw detection of train wheelsets, and more specifically relates to a probe array used for an online dynamic flaw detection device for train wheelsets. Background technique [0002] With the rapid development of China's railways, the speed of vehicles is getting faster and faster, the crossing roads are getting longer, the running density is getting higher and higher, and the train load is getting heavier. The train wheel is an important part of the running part, and the safety of the train wheel is the guarantee of the safe operation of the train. [0003] At present, the layout of the probe array of the on-line automatic flaw detection device for train wheelsets on the market is unreasonable, the type of defect detection at the same position is single, the detection accuracy is low, and defects are prone to missed detection. [0004] Therefore, how to improve the effective detection of train wheels is ...
