Description

Technical Field

[0001] The utility model relates to the technical field of track flaw detection, in particular to a track flaw detection trolley for railway maintenance. Background Art

[0002] Flaw detection refers to the detection of cracks or defects inside metal materials or components. Common flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetrant flaw detection, eddy current flaw detection, gamma ray flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without chemical changes. The rail flaw detection trolley is a special equipment installed on the track and mainly used to detect track damage. Its principles are mainly electromagnetic rail flaw detection and ultrasonic rail flaw detection. At present, the electromagnetic rail flaw detection method is gradually replaced by ultrasonic flaw detection. When performing ultrasonic flaw detection, debris on the track will affect the flaw detection effect, and the existing ultrasonic probe uses contact sliding and its friction loss greatly shortens the probe's service life.
