Steel rail fat edge grinding device and steel rail grinding wagon
The invention discloses a steel rail fat edge grinding device and a steel rail grinding wagon. The grinding device comprises a frame arranged at the bottom of the steel rail grinding wagon, a traction mechanism mounted between the frame and the bottom of the steel rail grinding wagonfor transmitting traction force and driving the steel rail grinding unit to perform grinding operation along a rail, and a steel rail polishing unit mounted on the frame and configured into an end face polishing unit or a cambered surface polishing unit. The end face grinding unit is used for conducting targeted grinding on the fat edge of the inner side of the steel rail, and the cambered surface grinding unit is used for conducting profile enveloping grinding on the steel rail. The technical problems that an existing grinding device is single in strategy, the grinding mode cannot be adjusted according to actual needs, the requirement for large grinding amount cannot be met at the same time, plastic fat edges of the steel rail cannot be removed, and what can be guaranteed is that the profile and the surface roughness of the ground steel rail meet the requirements can be solved.
本发明公开了一种钢轨肥边打磨装置及钢轨打磨车，打磨装置包括：设置于钢轨打磨车底部的车架；安装于车架与钢轨打磨车的车体底部之间，用于传递牵引力并带动钢轨打磨单元沿轨道打磨作业的牵引机构；以及安装于车架上的钢轨打磨单元，钢轨肥边打磨单元能被配置成端面打磨单元或弧面打磨单元。端面打磨单元用于对钢轨内侧的肥边进行针对性打磨，弧面打磨单元用于对钢轨进行廓形包络磨削。本发明能解决现有打磨装置策略单一，无法根据实际需求调整打磨方式，不能同时满足较大磨削量要求，去除钢轨塑性肥边，又能够保证打磨后钢轨廓形、表面粗糙度满足要求的技术问题。
