Embodiment Construction
[0064] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0065] like image 3 Shown, a kind of train wheel flaw detection detection method, this wheel flaw detection detection method comprises the following steps:
[0066] S1. After the high-speed train enters the detection line, the worker operates to adsorb the vacuum powerful suction cup 11 of the detection arm on the car body of the train close to the detected wheel 4 .
[0067] S2. The control module of the ground trolley 2 sticks the probe module 13 on the detected wheel 4 according t...

The invention discloses a train wheel flaw detection method. The method comprises the following steps: S1, adsorbing a detection arm on the body of a train; S2, firmly attaching a probe module to a detected wheel; S3, starting a high pressure water pump to clean the wheel and provide coupling water for the probe module; S4, causing the probe module to start the detection; S5, completing, by an ultrasonic signal collecting and processing module, processing and comparison works of an ultrasonic signal of the detected wheel; and S6, completing the non-destructive detection of the detected wheel.Various operations of the train wheel flaw detection method disclosed by the invention are easily performed, the flaw detection can be conveniently performed on the train wheels on railways in the field without trenches, the operation method is simpler, the operations are more flexible, and the operation and maintenance requirements of the equipment are low.
Description
technical field [0001] The invention belongs to the technical field of train wheel flaw detection, in particular to a train wheel flaw detection method. Background technique [0002] As of March 2018, the operating mileage of my country's high-speed railways exceeded 25,000 kilometers, accounting for two-thirds of the total operating mileage of high-speed railways in the world. Rich experience and other advantages. The high-speed EMUs CRH and Fuxing which run on high-speed railways are the main force of trains in high-speed railway operation. [0003] The wheel is the main part of the running part of the high-speed train, and it is an important link that affects the safe operation of the train. Therefore, it is necessary to carry out flaw detection on the wheel set to determine whether there are defects such as wear and tear on the wheel, so as to provide support for maintaining the wheel to a good technical state . Once the wheel fails, it will directly endanger the drivi...
