Description

Technical Field

[0001] This application relates to the field of train wheel inspection technology, and in particular to an integrated measuring ruler and method for measuring the inner distance of wheelsets and axle disc wear. Background Technology

[0002] With the rapid expansion of my country's high-speed rail network and the continuous increase in the operating mileage of high-speed trains, the safety maintenance and efficient repair of high-speed trains have become crucial aspects of ensuring railway transportation safety. As a key component of the high-speed train's running system, the wheelset's dimensional parameters directly affect the train's running stability, track compatibility, and braking performance. During the maintenance of high-speed train wheelsets, the rational application of maintenance techniques allows for the timely handling of components requiring repair or replacement. This ensures the overall operational safety and stability of the high-speed train, bringing significant economic and social benefits to the railway company.

[0003] Traditional wheelset dimension measurement relies on various independent measuring tools, such as wheel position gauges, vernier calipers, and internal measuring rulers. This necessitates numerous tools, complex operation, and inconsistent measurement standards, easily leading to cumulative errors. Especially when measuring the non-planar wear surface of axle-mounted brake discs, conventional tools struggle to accurately capture the true thickness. Furthermore, manual readings are susceptible to fatigue and environmental interference, severely impacting the reliability of measurement data and maintenance efficiency. Therefore, developing an integrated, digital, easy-to-operate, and standardized multi-functional wheelset measuring instrument is crucial for improving the standardization and intelligence of high-speed train maintenance operations. This design aims to achieve rapid and accurate measurement of multiple wheelset parameters through structural innovation and optimized measurement methods, reducing labor intensity and improving maintenance quality and efficiency, aligning with the intelligent and refined development trend of the railway industry.

[0004] Furthermore, traditional train wheel inspection methods involve manual inspection using measuring tools such as wheel diameter gauges, checking each wheel individually. Sometimes, each wheel may need to be inspected three times to ensure accuracy. This manual inspection method is inefficient. A typical train has 8 carriages and 32 wheelsets, making the inspection time-consuming. The process is also susceptible to variations in manual operation and measurement location, resulting in generally low accuracy. Traditional methods cannot quickly and accurately determine the actual condition of wheelsets, leading to some wheelsets operating with defects while others are prematurely retired without any issues. This not only poses safety hazards but also results in significant waste. Furthermore, traditional testing methods have the following drawbacks: First, the measurement is complex. Because the wear measurement area of ​​the axle-mounted brake disc is non-planar, vernier calipers cannot effectively measure the remaining wear thickness of the axle-mounted brake disc. After measurement by multiple devices, there is an accumulation of errors. Second, it is purely manual measurement. When measuring wheels or axle-mounted brake discs, the measuring tools have different measuring areas, resulting in inaccurate measurement data and making it impossible to standardize the data. Third, there are many types of existing measuring devices, which are inefficient, time-consuming, and cannot effectively guarantee accurate measurement in one go, often resulting in repeated operations. Fourth, the measuring instruments are heavy and cumbersome to use, requiring manual straightening. Summary of the Invention
