Embodiment Construction

[0031] In order for those skilled in the art to better understand the technical solutions provided by the present invention, the following will be described in conjunction with specific embodiments.

[0032] figure 1 , figure 2 , Figure 3a , Figure 3b , Figure 4 It is shown that a specific embodiment of the present invention is: a phased array ultrasonic detection device and method for a solid axle, using the deflection and focusing characteristics of the phased array ultrasonic to detect the axle journals 67, 68, wheel Seat 71,72, gear seat 73, holding journal 74,75, shaft body 76 positions are scanned. The top running wheel device 2 drives the wheel pair to perform circumferential motion 1 . When using this equipment for axle inspection, the ultrasonic coupling agent is oil, and under the condition that the surface of the axle shaft end and the journal surface of the axle are kept wet, the full coverage scan of all areas of the entire axle can be completed by rotati...

Abstract

The invention discloses a phase array ultrasonic detecting device and method for a solid axle. The phase array ultrasonic detecting device and method are suitable for detection of various solid axles. Phase array ultrasonic probes are arranged on an axle neck part and the end face of the axle respectively, the distance between the center of the phase array probe on the end face of the axle and the circle center of the end face of the axle, the sending and receiving angles are -40 degrees to 40 degrees, the distance between the center of the phase array probe on the axle neck part and the end face of the axle is 55mm to 252mm, and the sending and receiving angles are 30 degrees to 70 degrees. Compared with the prior art, the phase array ultrasonic detecting device and method can be used for all covering detection of parts such as the axle neck of the axle, a wheel seat, a gear seat, an embracing journal and an axle body, the number of the used phase array probes is small, the probes do not need to move back and forth, detection efficiency is high, the phase array ultrasonic detecting device and method adapt to various different axles, and manual intervention is not required.

Description

technical field [0001] The invention relates to the field of axle detection, in particular to a phased array ultrasonic detection device and method for a solid axle. Background technique [0002] With the development of railway transportation in the direction of high speed and heavy load and the extension of maintenance kilometers of locomotive depots, higher requirements are put forward for the quality of locomotive running parts. The axle is one of the key parts of the mechanical running part of the locomotive. It plays the role of transmitting static load, traction force and braking force to the rail during operation. In addition, it also rigidly bears the vertical and horizontal forces from the rail joints, turnouts, and uneven lines. It is a Components with complex forces and harsh working conditions urgently need to detect internal and external defects of the axle. Therefore, in order to avoid accidents during operation of defective axles and ensure the safety of the ...
