Grinding method for irregularity of rail surface of high-speed railway steel rail welded joint within 3m range
The invention relates to a method for polishing irregularity of a rail surface of a high-speed railway steel rail welded joint within a 3m range, and belongs to the field of railway line engineering, which comprises the following steps of: firstly, determining an abnormal vibration section where the impact force of a wheel rail of a high-speed railway is too large or the noise of the wheel rail is abnormal; collecting rail surface irregularity data of a high-speed railway steel rail welding joint within a range of 3m in the abnormal vibration section; meanwhile, steel rail profile data within the 3m range of a steel rail welding joint needs to be collected, and the rail surface state is recorded. Then statistical analysis is carried out on the collected rail surface irregularity data, and a corresponding small machine grinding scheme is designed for an over-limit steel rail welding joint; according to the designed polishing scheme, small-sized polishing mechanical equipment is adopted to polish the irregularity of the rail surface of the steel rail welding joint, and the consistency of the profile of the steel rail within the polishing range needs to be ensured. And finally, carrying out quality acceptance on the irregularity of the rail surface and the profile of the steel rail within a 3m range of a steel rail welding joint. Through the method provided by the invention, the problems of unsmooth low stepping caused by common over-polishing, abnormal light band after driving caused by poor profile of the steel rail and the like are completely eradicated.
本发明一种高速铁路钢轨焊接接头3m范围内轨面不平顺打磨方法，属于铁路线路工程领域，首先需确定高速铁路轮轨冲击力偏大或者轮轨噪声异常的异常振动区段，并对异常振动区段内高速铁路钢轨焊接接头3m范围内轨面不平顺数据进行采集；同时还需采集钢轨焊接接头3m范围内钢轨廓形数据，记录轨面状态。随后对采集后的轨面不平顺数据进行统计分析，对超限钢轨焊接接头设计相应的小机打磨方案；根据设计的打磨方案采用小型打磨机械设备进行钢轨焊接接头轨面不平顺打磨实施，要保证打磨范围内钢轨廓形的一致性。最后对钢轨焊接接头3m范围内轨面不平顺、钢轨廓形进行质量验收。通过本发明提出的方法，杜绝出现常见的过打磨造成低踏不平顺、钢轨廓形差造成的行车后光带异常等问题。
