Description

Technical Field

[0001] This invention relates to the field of rail straightening technology, and in particular to a data acquisition device for turnout straightening equipment. Background Technology

[0002] Rails are a crucial component of railways, and turnouts are an essential part of the railway rail system, guiding trains to switch tracks and connecting two tracks to facilitate train crossings. Compared to ordinary rails, turnouts have a more complex structure. To meet the demands of train operation, original turnout rail components must undergo a straightening process to be processed into finished rails with different cross-sectional shapes, specific curvature, or bending angles. Currently, in the actual straightening process, the position of the jacking pick, the span of the jacking support, and the stroke of the jacking pick are all determined by worker experience. Using manually determined parameters often fails to meet national standards for turnout rail components, requiring multiple straightening operations to achieve the required precision. Furthermore, inaccurate judgment of straightening parameters can lead to workpiece scrap. Therefore, there is an urgent need to automate the production of turnout rails to replace traditional manual methods.

[0003] To summarize these human experiences for the research of intelligent algorithms for machines, we designed a data acquisition device for turnout straightening equipment. The device collects straightening data during the worker's work process for subsequent intelligent research.

[0004] This design presents a data acquisition device for turnout straightening equipment, primarily comprising a pressure sensor, a displacement sensor, a display screen, an industrial control computer, and a touch screen. These hardware components work together on the older turnout straightening equipment to acquire, record, store, and retrieve displacement and pressure data. The acquired data is used to summarize straightening experience, providing data correction and guidance for finite element simulations and on-site manual straightening, thus offering a theoretical foundation for achieving intelligent straightening.
