On-line repairing method for railway turnout and rail car
The invention discloses an on-line repairing method of a railway turnout and a rail car, and relates to the technical field of rail maintenance, and the on-line repairing method comprises the following steps: carrying out full-rail contour milling and top surface grinding on a steel rail on a non-fork center side; carrying out interval division on the steel rail on the fork center side, and carrying out milling and grinding repair in different modes on each interval; a rail car with a plurality of grinding or milling and grinding tool combinations is adopted, a milling and grinding operation mode is adopted in areas such as a straight stock rail and a curved stock rail of a turnout and front and rear linear sections of the turnout, and a grinding operation mode is adopted near a frog, a movable point rail and a switch rail, so that the full-rail-profile operation interval of a steel rail in a frog center area is increased; the turnout section diseases are repaired through one-time or several-time operation, the repairing effect is good, energy consumption is low, operation efficiency is high, and the working environment is good.
本发明公开了一种铁路道岔的在线修复方法及轨道车，涉及轨道维修技术领域，包括：对非叉心侧的钢轨进行全轨轮廓铣削和顶面磨削；对叉心侧的钢轨进行区间划分，并对各个区间进行不同方式的铣磨修复；采用带有若干个打磨或者铣磨刀具组合的轨道车，在道岔的直基本轨、曲基本轨以及道岔的前后直线段等区域采用铣磨的作业方式，在辙叉和可动心轨、尖轨附近采用打磨的作业方式，提升了增大叉心区钢轨全轨廓作业区间，一次或几次作业修复道岔区间病害，修复效果好，能耗低，作业效率高，工作环境良好。
