Abstract

The invention provides a wheel type probe fixing system for vertical flaw scanning. The system comprises a fixing frame, a pair of walking wheels and a water wheel seat; at least three probes are arranged on the water wheel seat; and the probes comprise at least one transmitting probe or receiving probe; ultrasonic waves emitted by the transmitting probe can be received by a receiving probe after being subjected to twice mirror reflection of a vertical flaw in a track and the bottom surface of the track; the multiple probes on a probe support can be matched to scan the vertical flaw at multiple heights in a flaw detection area. According to the wheel type probe fixing system for vertical flaw scanning, the walking wheels can be automatically attached to the track under the action of side baffles and reset springs, and it is further ensured that the probes are kept in the center of the track under the action of a motor; and through cooperation of the multiple probes, continuous scanning of the whole height range in the flaw detection area is achieved, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of rail flaw detection, in particular to a wheel probe regulation system for vertical damage scanning. Background technique [0002] During the welding process of the track, due to unstable welding equipment, improper selection of process parameters, and quality problems such as the base metal of the track, defects occur during the welding process, including bulky ones, such as looseness and slag inclusions, etc.; Such as micro-cracks, gray spots, lack of welding, etc., in order to ensure driving safety, defects must be detected early. [0003] At present, ultrasonic probes are mainly used for damage detection. Since the medium inside the track is uniform, the ultrasonic waves will be mirror-reflected after encountering damage; using this principle, a wheel-type probe that can be installed is disclosed in the Chinese patent application CN206114598U. In the bracket, multiple ultrasonic probes with different ...
