上海轨道交通11号线钢轨铣磨车铣磨作业分析

Analysis of Rail Milling Operation on Shanghai Metro Line 11

上海轨道交通11号线客流持续增加,钢轨表观病害问题日益突出。为了对钢轨的廓形进行修整,上海轨道交通引进了大型装备钢轨铣磨车。基于钢轨铣磨车在11号线的现场作业情况,通过分析钢轨廓形状态、波磨、粗糙度和噪声,评价钢轨铣磨车对钢轨的整形效果;结合现场经验总结出了有利于提升钢轨铣磨效果的控制措施,探索出了一套钢轨铣磨车作业流程和其中的关键控制措施,可为钢轨铣磨车正线作业提供参考。

In recent years,since the passenger flow of Shanghai metro Line 11 continues to increase,problems of apparent rail defects are increasingly prominent.In order to trim the profile of metro rails,Shanghai metro has introduced in a large-scale equipment rail milling car.According to the field operation of rail milling car on Shanghai metro Line 11,rail profile status,corrugation,roughness and noise are analyzed,the shaping effect of rail milling car on rail is evaluated.On this basis,and combined with field experiences,the control measures to improve the rail milling effect are summarized.A set of rail milling operation process and key control measures in the process are explored to provide reference for the follow-up main line milling operations.
