Embodiment

[0040] Figure 1-6 As shown, a specific embodiment of the present invention is: an ultrasonic detection device for wheel spoke defects of a locomotive vehicle, comprising an ultrasonic array probe connected to the probe bracket 97 connected to the control mechanism, and the ultrasonic probe is placed on the tread surface of the wheel 1 of the wheel set 14, the bottom of the wheel rim 12 is placed on the top wheel 91 and the runner 92 of the top runner device; the ultrasonic probe is connected with the data acquisition, data processing and control computer. Ultrasonic probes are four pairs of probes composed of transmitting probes and receiving probes and six probes integrating transceivers, among which: the range of the transmitting angle or receiving angle of each probe in the four pairs of probes is 15-33°. The included angle between the rolling circles, that is, the range of the torsion angle is 5 to 35°, and the emission angle of the transmitting probe in each pair of prob...

Abstract

The invention relates to an ultrasonic testing device of a wheel spoke of an engine vehicle, wherein, an ultrasonic probe thereof comprises four pairs of single-emission and single-receiving probes and six probes integrated with emission and receiving. In the four pairs of probes, the emission angle or receiving angle of each probe is 15-33 degrees; the torsion angle is 5-35 degrees; and each pairof probes is arranged according to the set position. In the six probes integrated with emission and receiving, two normal probes are respectively arranged at two sides of a rolling circle; the axialdistance with the rolling circle is 1-8 mm; the emission angles of two angle probes are parallel to the rolling circle surface and the axial distance with the rolling circle is 1-8 mm; and two probeswith the emission angle of 1-10 degrees are respectively arranged at two sides beside the rolling circle and the axial distance with the rolling circle is 1-4 mm. The device can carry out all-around detection on the defects of each type of wheel spoke; the detection process is free of manual work participation with high detection rate; and the detection method is simple and the detection result isreliable.

Description

technical field [0001] The invention relates to an ultrasonic detection device for wheel spoke defects of locomotive vehicles. Background technique [0002] The wheel is a key component of the rolling stock running system including the EMU, and its basic structure is as follows: Figure 5 As shown, it includes: wheel rim 12, tread surface 14, wheel rim 11, wheel spoke 15, wheel spoke plate hole 17, wheel hub 18. The internal state of the wheel 1 and the cracks on the surface are directly related to driving safety. The great development of railway speed-up and a large number of high-speed EMUs put forward higher requirements for the quality of wheels. In order to ensure the quality of the wheel set and ensure the safety of the train, it is necessary to conduct regular flaw detection on the rim and spoke of the wheel. At present, the most effective method of wheel flaw detection is ultrasonic testing. The principle is: if there are pores, cracks, delamination and other defec...
