Description

Technical Field

[0001] The utility model relates to the technical field of winding devices, in particular to a rail vehicle wheel wear detection device. Background Art

[0002] Wheels are a type of wheel forgings, primarily used in lifting machinery, transport machinery, mining machinery, and other fields, with mining machinery being the most common. Wheels come in a variety of types and can be categorized by material into cast steel wheels and rolled steel wheels. Cast steel wheels are primarily made through a casting process, while rolled steel wheels are made through a rolling process. Furthermore, depending on the specific application scenario and design requirements, wheels may also be made of other special materials or undergo special treatments to improve their wear resistance, corrosion resistance, and service life.

[0003] Since railcar wheels carry heavy objects, long-term contact between the wheels and the rails can easily lead to wear and out-of-roundness of the outer rims, which will seriously affect the safe operation of railcars. Therefore, railcar wheels need to be inspected regularly.

[0004] The existing technology for detecting out-of-roundness of railcar wheels generally includes:

[0005] 1. Visual inspection method: After jacking up the wheel, rotate the wheel quickly and observe with the naked eye whether there is any shaking or wiggling. If significant shaking or wiggling is observed, it may indicate that the wheel is out of round. This detection method is only suitable for wheels with large wear and out of roundness. For wheels with small wear and out of roundness, the wheel will not shake during rotation and the amplitude is very small and difficult to detect with the naked eye.

[0006] 2. Use laser displacement sensors to measure the radial and axial runout of the wheel. This method can achieve dynamic quantitative detection of wheel out-of-roundness. This detection method can accurately measure the out-of-roundness of the wheel. However, laser displacement sensors are expensive and inconvenient to use. They require professional personnel to operate, which increases costs. Small companies find it difficult to equip such special detection equipment. Therefore, a rail vehicle wheel wear detection device is designed to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to propose a railway vehicle wheel wear detection device.

[0008] The technical problem to be solved by the utility model is to provide a rail vehicle wheel wear detection device to solve the problem that the prior art is inconvenient in detecting the wear and out-of-roundness of rail vehicle wheels.

[0012] Preferably, the arc-shaped plate matches the arc-shaped groove, and the arc-shaped plate is made of rubber.

[0013] Preferably, the inner side of the arc plate is inclined with a reduced thickness component, and when the second spring is in a naturally extended state, the inner end of the arc plate is completely embedded in the arc groove, and the outer end of the arc plate extends out of the arc groove.

[0014] Preferably, an annular strip is fixedly provided at the center of the outer surface of the sleeve ring, and an annular groove is provided at the center of the inner surface of the rotating ring.

[0015] Preferably, the annular strip matches the annular groove, and the annular strip is embedded in the annular groove.
