Track vehicle rim and tread flaw detection probe assembly system

Abstract

The invention discloses a track vehicle rim and tread flaw detection probe assembly system. The track vehicle rim and tread flaw detection probe assembly system comprises a tread flaw detection probe assembly and a rim flaw detection probe assembly. The tread flaw detection probe assembly leans on the tread of a wheel through a mechanical arm; the rim flaw detection probe assembly leans on the rim surface of the wheel through the mechanical arm; the tread flaw detection probe assembly can automatically detect wheel tread and rim defects from the tread in an online mode and is high in detection efficiency, accurate in detection result, simple in structure and convenient to use and operate; the rim flaw detection probe assembly can automatically detect wheel rim surface and tread detects from the inner lateral side of the rim in on online-mode and is high in detection efficiency, accurate in detection result, simple in structure and convenient to use and operate.

Description

technical field [0001] The invention relates to an ultrasonic wheel flaw detector, which is specially designed for routine flaw detection of high-speed EMUs, and in particular to a rail vehicle wheel rim and tread flaw detection probe assembly system. Background technique [0002] The wheels of rail vehicles are subjected to large alternating stress for a long time during operation, and cracks may occur inside them, causing potential safety hazards. For this reason, ultrasonic flaw detection should be carried out regularly on the wheels. In the past, wheel flaw detection was manually operated with a hand-held probe holder, which was very inefficient. In recent years, a kind of non-dropping wheel ultrasonic flaw detection equipment has been developed at home and abroad, that is, without removing the wheel, but under the condition that the wheel is normally installed on the car, the flaw detector moving in the ditch at the bottom of the car performs automatic flaw detection. ...

AI Technical Summary

Problems solved by technology

The wheel rim flaw detection probe assembly and the wheel tread flaw detection probe assembly are the key components of the equipment. The original technology cannot continuously detect the detection area; the number of probes is large; the probe frame is large in size; the detection range is small and the adaptability is poor; the coupling is poor; Large liquid consumption; low work efficiency and many other defects

As a result, the detection working state is unstable, and frequent missed and false detections occur.
