Description

Technical Field

[0001] The utility model relates to the field of ultrasonic flaw detection, in particular to a wheelset ultrasonic phased array flaw detector. Background Art

[0002] Ultrasonic phased array flaw detection is a method of inspecting part defects by using the characteristic that ultrasound can penetrate deep into metal materials and reflect at the edge of the interface when entering from one section to another. When the ultrasonic beam passes from the surface of the part through the probe into the metal, reflected waves are generated when encountering defects and the bottom of the part, forming pulse waveforms on the fluorescent screen. The location and size of the defects are judged based on these pulse waveforms. Ultrasonic phased array flaw detection technology is also used in the inspection of hollow axles of wheelsets in railway transportation. Ultrasonic waves can be used to complete daily inspections of hollow axles of wheelsets of EMUs to ensure the safe operation of railway EMUs.

[0003] The utility model with the existing announcement number CN217156415U discloses an ultrasonic flaw detection device for the hollow shaft of a railway wheelset. A camera is installed on one side of a movable plate, and the position of the central axis of the wheelset is observed by the camera. Then, by controlling the first forward and reverse motor and the second forward and reverse motor to work, the movable plate is pushed to one side by the rack and the gear respectively, thereby changing the horizontal position of the probe. The threaded rod is driven to rotate by the second forward and reverse motor to change the vertical position of the probe, so that the probe can be accurately inserted into one end of the central axis of the wheelset.

[0004] In the process of implementing the utility model, the inventors found that there are at least the following problems in this technology: the probe and the camera are exposed to the outside, and after use, there is a lack of protective devices for the probe and the camera, so that the probe and the camera may be accidentally touched by other objects, causing damage to the probe and the camera. Therefore, a wheelset ultrasonic phased array flaw detector is now proposed. Utility Model Content
