Large and small machine combined railway turnout full-coverage profile polishing method
The invention discloses a large and small machine combined railway turnout full-coverage profile polishing method. A turnout large and small machine operation polishing scheme is designed according todetermined large and small machine operation division and turnout steel rail profile design; the large machine polishing scheme is characterized in that the power percentage, speed and angle of a large machine need to be given, and the sleeper number range of each turnout is refined; a polishing scheme is designed according to the deviation between the profile of the steel rail in the large machine polishing area and the designed profile, and the polishing frequency is calculated; and the small machine polishing scheme is designed into a small machine priority polishing scheme and a normal polishing scheme. In the large and small machine grinding processes, the field operation quality is controlled, and the scheme is optimized. The operation performance of the turnout large and small machines is deeply analyzed, the operation advantages of the turnout large and small machines are brought into full play, turnout full-coverage profile polishing is achieved, the overall smoothness of a turnout zone is improved, and the vehicle passing performance is improved.
本发明公开一种大小机结合的铁路道岔全覆盖廓形打磨方法，根据确定的大小机作业分工以及道岔钢轨廓形设计，设计道岔大小机作业打磨方案；其中，大机打磨方案需给定大机的功率百分比、速度、角度，细化至每一组道岔的轨枕号范围；根据大机打磨区域钢轨廓形与设计廓形的偏差，进行打磨方案设计，计算打磨遍数；小机打磨方案设计为小机优先打磨方案和正常打磨方案两部分。大小机打磨过程中，对现场作业质量控制、以及方案优化。本发明深入分析了道岔大小机作业性能，充分发挥了道岔大小机作业优势，实现了道岔全覆盖廓形打磨，提高了岔区整体平顺性，改善了车辆通过性能。
