Technical Field

[0001] The utility model relates to the technical field of vehicle body flaw detection, and in particular to a vehicle body crack detection device. Background Art

[0002] After long-term use, cracks often appear on the train body. After the train is inspected by ultrasonic flaw detection, how to accurately mark the crack location is a problem that needs to be solved urgently.

This utility model not only improves the convenience of operating the flaw detection device and effectively reduces the labor intensity of personnel, but also facilitates marking of cracked sides of the train body, thereby facilitating the timely identification of the crack location by maintenance personnel, and also facilitates the disassembly and maintenance of the ultrasonic detection body.

[0004] After completing ultrasonic testing, the above-mentioned train body crack detection device uses a water pump to spray pigment through a liquid storage tank to the cracks on the train for marking. However, this design causes pigment to splatter due to direct injection through an infusion pipe, which in turn causes the crack position mark to become blurred or even deviate.
