Description

Technical Field

[0001] The utility model relates to the technical field of probes, and more specifically to an ultrasonic probe for cracks in a connecting rod pin of a locomotive wheel set. Background Art

[0002] Ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument. It can detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) inside the workpiece quickly, conveniently, non-destructively and accurately. It can be used both in laboratories and on-site.

[0003] The utility model patent with publication number CN203849217U discloses an ultrasonic probe for cracks in a locomotive wheel set connecting rod pin. The existing non-destructive testing process for connecting rod pins is to perform magnetic particle flaw detection on the detection part when the connecting rod pin is in a single-piece, independent finished product state, and can only detect crack defects on the surface of the connecting rod pin. During the operation of the locomotive, occasional wheel set connecting rod pin fracture accidents occur; for the wheelset connecting rod pin in an assembled state, since its detection part is not exposed, the use of magnetic particle flaw detection is ineffective. The above utility model realizes the crack defect detection of the locomotive wheel set in a single-piece, independent finished product state, an assembled state, that is, a non-single-piece and independent, non-disassembled state, that is, a non-disassembled state during maintenance, as well as the in-service online detection, real-time tracking and monitoring of the connecting rod pin, thereby improving product quality.

[0004] However, in actual use, when testing a large number of connecting rods, the fixation between the connecting rods and the ultrasonic probes is inefficient, which reduces the detection efficiency of the connecting rods. At the same time, waste will stick to the outside of the used connecting rods, which will affect the accuracy of the ultrasonic probe detection during testing. Utility Model Content
