Problems solved by technology

And literature: Beijing leading LU wheel rim and spoke flaw detection system needs to be arranged in the ditch in the storage line, and the wheels need to be jacked up. These two kinds of wheel defect detection devices are large in size, complex in structure, low in efficiency and low in reliability, and cannot be realized Real-time online detection is difficult to control the quality. The Tangshan Baichuan liquid immersion method dynamically detects the wheels. The probe is fixed in the water tank. It is impossible to cover the wheels completely. The detection effect is not good due to external factors. The Institute of Metal and Chemistry, China Academy of Railway Sciences In addition, the flaw detection information of the current flaw detection equipment cannot enter the "maintenance management information system" required by the railway management department, and the flaw detection information has become an information island, which cannot achieve resource sharing and rational utilization.

Embodiment 1

[0025] The follow-up locomotive and vehicle ultrasonic flaw detector of this embodiment includes a fixed workbench 1, an acquisition device 2, and an ultrasonic transducer device 3. The acquisition device is fixed on the fixed workbench 1, and the ultrasonic transducer device 3 is fixed on the fixed workbench 1. On the fixed workbench 1, the fixed workbench 1 is fixed on the shock absorber arm of the vehicle or the position of the vehicle body,

[0026] The ultrasonic transducer device 3 includes: a transducer carrier action mechanism 31, a probe 32, an encoder 33, a position sensor 34 and a couplant circuit 35, the encoder 33 is arranged at the front and back of the probe 32, and the couplant circuit 35 Arranged at the corresponding position with the encoder 33, the probe, the encoder and the couplant circuit are arranged on the transducer carrier action mechanism 31, and the position sensor 34 is arranged on the transducer rotation mechanism 31. The present invention comprehe...

Embodiment 2

[0028] Such as figure 1 As shown, in the follow-up rolling stock ultrasonic flaw detector of this embodiment, when the wheel of the rolling stock needs to be inspected for defects, the defect detection device is installed on the special adapter, and it is closely fitted to connect the couplant pipeline. Flaw detection is realized under low-speed motion state.

[0029] Work process and principle of the present invention are:

[0030] When working, the following type rolling stock ultrasonic flaw detector is directly fixed on the working platform 1 on the shock absorbing arm of the rolling stock. The working platform 1 is connected with a movable flaw detection device 2. The flaw detection device includes an ultrasonic probe, an encoder and a coupling The agent pipeline, the sampling proximity switch, the acquisition device 2, and the connecting rotating mechanism 3 of the fixed flaw detection device. Under normal working conditions, the connecting rotating mechanism follows t...

Embodiment 3

[0034] Such as Figure 5 As shown, the follow-up ultrasonic flaw detector for locomotives in this embodiment is installed on the main body 7 of the shock absorber arm.

[0035] Such as Figure 6 , Figure 7 As shown, the follow-up type locomotive and vehicle ultrasonic flaw detector of this embodiment is installed on the vehicle body 5 .

[0036] The similarities and differences between its working method and Embodiment 1 are that the installation method is moved to the vehicle body, and the transducer detection device is fixed above. The transducer carrier action mechanism is different from the transducer carrier action mechanism on the shock absorber arm fixing mechanism.
