Description

Technical Field

[0001] The utility model relates to the technical field of locomotive wheel detection, in particular to an automatic detection device for surface cracks of a locomotive wheel. Background Art

[0002] The automatic detection device for surface cracks on locomotive wheels has important application value in the field of railway transportation. With the development of railway transportation, the quality of locomotive wheels directly affects the operation safety and service life of trains. In order to ensure the safety of train operation, regular inspection of locomotive wheels, especially the detection of surface cracks, is an indispensable link. Traditional detection methods mainly rely on manual and simple mechanical equipment, which is not only inefficient, but also prone to missed detection or false detection. Modern automatic detection devices combine advanced sensing technology and control technology to achieve efficient and accurate detection of wheel surface cracks, greatly improve detection efficiency and reliability, and ensure the safety and stability of train operation. Such devices are widely used in railway vehicle maintenance bases, wheel manufacturing plants and rail transit systems, and are important technical equipment to ensure the safe operation of railways.

[0003] The existing authorization announcement number of CN216926106U is "a railway locomotive wheel detection device", which includes a mounting base, a lifting mechanism, a driving motor, a bearing seat and a detection component; the screw lift includes: a screw lift arranged on the mounting base; guide columns arranged on both sides of the screw lift. The screw lift of the railway locomotive wheel detection device accurately lifts the mounting platform on the top of the lifting mechanism under the drive of the servo motor, and then synchronously adjusts the height of the driving motor, the bearing seat and the detection component, so that the driving wheel located at the output end of the driving motor and the driven wheel fixed on the bearing seat, as well as the detection component can adapt to locomotive wheel detection devices of various models and sizes, so as to achieve the purpose of detecting multiple locomotive wheel detection devices with one set of detection devices.

[0004] However, the current locomotive wheel inspection equipment has some defects in actual use. First, the adjustment and operation of traditional inspection equipment mostly rely on manual labor, and it is difficult to make precise adjustments according to wheels of different specifications, resulting in low inspection efficiency and low accuracy. Secondly, the wheel needs to remain stable during the inspection process, but the existing device has limited effect on the fixing and limiting of the wheel, and the wheel is prone to shaking or displacement, affecting the accuracy of the inspection results. In addition, when conducting inspections, the existing equipment can usually only cover part of the surface of the wheel, and cannot achieve all-round automatic inspection. There are blind spots in the inspection, and it is easy to miss small cracks, affecting the safety of the wheel. Furthermore, the traditional inspection method requires a lot of manual operation, which is labor-intensive and prone to human errors, further reducing the reliability and efficiency of the inspection.
