Description

Technical Field

[0001] The utility model relates to the field of rail detection, in particular to a rail flaw detection device. Background Art

[0002] The rail flaw detection device is an instrument used for rail maintenance and detection. It mainly detects the rails by ultrasonic means to accurately find the position of the rail flaws. It is used in conjunction with the maintenance of the flaws and is widely used in rail detection and maintenance occasions. When the existing rail flaw detection device is used, it is generally used to detect the rails through an ultrasonic flaw detector. However, before the detection, the stains on the rails cannot be removed, resulting in the stains affecting the detection accuracy and the inability to accurately perform the detection. In addition, when the ultrasonic flaw detector performs mobile detection on the rails, the movement of the device will produce deviations, and it cannot always be parallel to the center of the rails during movement, which also results in the inability to accurately and stably move the detection on the rails.
