Steel rail corrugation grinding method combining traditional grinding and rapid grinding
The invention discloses a steel rail corrugation grinding method combining traditional grinding and rapid grinding, and is suitable for the technical field of steel rail corrugation engineering. The method comprises the steps that special detection is conducted on a steel rail before grinding, a corresponding steel rail corrugation treatment scheme is formulated according to the special detection result, steel rail profile grinding is conducted through a traditional grinding wagon, corrugation with the wavelength smaller than 300 mm is emphatically treated, meanwhile, surface fatigue diseases are removed, and a rail top hardened layer is eliminated; then, through quick grinding wagon operation, corrugation with the wavelength not smaller than 300 mm is emphatically treated, and meanwhile the overall smoothness of a steel rail line is improved; a polishing operation scheme is designed, and a corrugation mode process is optimized; and polishing operation is executed according to the designed operation scheme, and quality acceptance after polishing is carried out. According to the method, high-efficiency, high-quality and high-economical-efficiency treatment of steel rail corrugation is achieved, the method is suitable for ordinary-speed railways and high-speed railways, the wheel-rail contact relation can be improved, the service life of the steel rail can be prolonged, and the safety and stability of vehicle running can be improved.
本发明为一种传统与快速打磨相结合的钢轨波磨打磨方法，适用于钢轨波磨工程技术领域。本发明方法包括：对打磨前钢轨进行专项检测，根据专项检测结果制定相应的钢轨波磨治理方案，先通过传统打磨车进行钢轨廓形打磨，重点处理波长300mm以下的波磨，同时去除表面疲劳病害，消除轨顶硬化层；后通过快速打磨车作业，重点处理波长不小于300mm的波磨，同时改善钢轨线路整体平顺性；设计打磨作业方案，优化波磨模式工艺；根据设计的作业方案执行打磨作业并进行打磨后质量验收。本发明实现了对钢轨波磨的高效率、高质量、高经济性的处理，对普速铁路及高速铁路均适用，能改善轮轨接触关系、延长钢轨使用寿命、提高车辆运行的安全性及平稳性。
