Embodiment Construction
[0040] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0041] A follow-up online wheel tread electromagnetic non-destructive testing probe device, combined with Figure 1 to Figure 9 As shown, it includes a detection rail 2 , an electromagnetic detection probe 3 , a wheel tread bonding device 4 , a buffer lifting device 5 and a moving travel device 6 .
[0042]There are two detection rails 2, parallel to each other, with a certain distance, used to make the wheel rim 11 move on the upper part, and make the wheel tread 12 exposed, leaving enough space for the electromagnetic detection probe 3. The detection rail 2 comprises a wheel rim moving track 21 and a base 22 arranged at the bottom of the wheel rim moving track 21, the wheel rim moving track 21 is in contact with the wheel rim 11, and the wheel rim moving track 21 is not in contact with the wheel tread 12. contact, so that the wheel...

The invention discloses a follow-up online wheel tread electromagnetic non-destructive detection probe device, which comprises two detection rails parallel to each other and with a certain distance, and several pairs of electromagnetic detection probes respectively arranged on the outside of the two detection rails at intervals on the same line. It is arranged on the wheel tread lamination device whose top end is in contact with the wheel tread and whose top height is higher than that of the electromagnetic detection probe. Each wheel tread lamination device is respectively arranged on the mobile traveling device through a buffer lifting device. The detection rail provided by the present invention can make the wheel tread be in a suspended state during the detection process, and the bonding of the wheel tread and the wheel tread fitting device can ensure that the electromagnetic detection probe is in direct contact with the wheel tread, and the buffer lifting device can adjust the electromagnetic detection probe and the wheel tread. The distance between the wheel treads and the moving device ensure that the electromagnetic detection probe can follow the wheel treads for mobile detection, realize the comprehensive detection of the wheel tread circumference, and ensure the continuity of detection.
Description
technical field [0001] The present invention relates to the technical field of rail vehicle wheel flaw detection, and more specifically relates to a follow-up online wheel tread electromagnetic non-destructive detection probe device, which realizes rapid detection of wheel magnetization and magnetic field distortion at defects through magnetic field coupling, and is the most promising online Wheel tread and rim defect detection device. Background technique [0002] The train wheel includes a wheel rim and a wheel tread, and the wheel tread is the surface that the train contacts with the rails during its travel. During the operation of the train, the wheel treads are often partially scratched due to braking or idling and slipping. After the scratches, the wheels will cause coupling vibration of the entire vehicle track system during the running of the train, endangering driving safety. Therefore, it is very important and necessary to detect and identify wheel tread abrasions...
