Description

Technical Field

[0001] The utility model relates to the technical field of rail detection equipment, in particular to a defect ultrasonic detection device for exothermic welding of rails. Background Technique

[0002] The rail ultrasonic detection device uses ultrasonic technology to perform non-destructive detection on rails, and can sensitively and efficiently detect the damages inside the rails, effectively improving the smoothness and comfort of train operation; during the use of the existing ultrasonic imaging detector for full-section detection of rails, it is not convenient for people to operate better, resulting in inconvenient detection of the full section of the rails, and thus inconvenient to better meet people's use requirements.

[0003] For example, the patent with publication number CN202122523757.7 discloses "An Ultrasonic Imaging Detector for Full-Section Detection of Rails". By setting through holes, the wires on the detector body can be better connected to the detection probes on the cross bar through the rotating tube, ensuring that the instrument can operate better, and thus facilitating better meeting people's use requirements.

[0004] When the ultrasonic detector is in use, it is necessary to use an external data cable to cooperate with the detection head to perform ultrasonic detection on the rails. However, the rails are mostly in an environment with a lot of dust. Due to too much dust, it may accumulate at the interface between the ultrasonic detector and the data cable, resulting in damage to the instrument due to too much dust, and thus being disadvantageous to the use of the ultrasonic detector, the data cable and the detection head.
