Abstract

The invention discloses a railway wheel tread scratch image dynamic detection device, belonging to the technical field of machinery detection equipment structure carrying out detection on railway (vehicle) wheel tread. The detection device comprises a plurality of scratch detection camera cases provided with built-in camera, a wheel positioning system, an image acquisition system and a control circuit are utilized, an industrial personal computer is utilized to detect wheel pair image shot by a camera which is fixedly arranged and wheel pair safety state. The device can be used for wheel pair detection on vehicles passing through main line of railway, wheel pair detection when motor train unit is put in storage and wheel pair detection when locomotive is put in storage and can dynamically measure fault state of wheel pair tread of train in normal operation, including wheel faults of scratch, stripping, ground pile and the like, so that overhauling person can timely handle the wheel fault of train and the train is ensured to operate safely.

Description

technical field [0001] The invention relates to a dynamic detection device for scratch images of railway wheel treads, which belongs to the technical field of mechanical equipment detection device structures, and specifically belongs to the technical field of mechanical detection equipment structures for detecting railway locomotive (vehicle) wheel treads. Background technique [0002] In railway operation, the running state of the running part, especially the wheel set, plays an important role in the safety of the train. Wheelset parameters that play an important role in safety include: rim wear, circumferential wear, tread abrasion, etc. When faults such as scratches, peeling, and rolling occur on the wheel tread, additional impact force will be generated on the rail during the operation of the train, which will reduce the life of the rail, and even cause cracks and fractures in severe cases. While hitting the rails, the abrasion fault also brings impact to the vehicle it...
