Problems solved by technology

If the power shaft has a material defect of 2 mm or more (transverse cracks are more dangerous), it will meet the scrapping standard of the Ministry of Railways; if it is not scrapped, continued use may cause the vehicle to break the shaft, derail and overturn
If there is a problem with the power shaft of the high-speed rail power car, the train will fly off the track, causing a tragedy of car crash

Abstract

The invention provides a nondestructive testing device for a high-speed rail hollow shaft, and relates to the field of nondestructive testing. The nondestructive testing device comprises a base, a fixing mechanism, a plurality of mounting seats, flaw detection devices and a power machine, the fixing mechanism is used for mounting the hollow shaft, the fixing mechanism is rotatably connected to the base and connected with the output of the power machine, and the mounting seats are mounted on the base. And the plurality of mounting seats are adjustable along the axial direction of the hollow shaft and are connected with the plurality of flaw detection devices one by one. Damage detection of the hollow shaft can be met, and use is convenient.

Description

technical field [0001] The invention relates to the field of nondestructive testing, in particular to a nondestructive testing device for a high-speed rail hollow shaft. Background technique [0002] At present, high-speed trains generally use hollow shafts, which can reduce the driving load, increase speed, and facilitate inspection. Since the power shaft is very important to driving safety, and internal defects are difficult to see with the naked eye, it must be detected by professional flaw detection equipment through ultrasonic electronics. . [0003] According to the requirements of the Ministry of Railways, the flaw detection of the hollow shaft is required every 30,000 kilometers for CRH2 bullet trains, and the flaw detection cycle for CRH5 bullet trains is 180,000 kilometers. Axle is a key component connecting train wheel sets, and has a great relationship with train safety. If the power shaft has a material defect of 2 mm or more (transverse cracks are more danger...
