Rapid steel rail grinding wagon
The invention relates to a rapid steel rail grinding wagon, which comprises a grinding wagon frame (5). A front bogie (4) and a rear bogie (4) are installed at the bottom of the grinding wagon frame (5), a grinding trolley (6) is installed between the front bogie (4) and the rear bogie (4), a functional room (7) is installed on the upper portion of the grinding wagon frame (5), and a dust suctiondevice (10) is installed in the functional room. By conducting low-grinding-amount pre-grinding and preventive grinding on the steel rail, germination of steel rail diseases can be effectively restrained, the service life of the steel rail is greatly prolonged, and wheel rail impact noise is reduced; by adopting a passive circumferential grinding principle, bidirectional driving operation and multi-vehicle reconnection can be realized, and the highest speed per hour of grinding operation can reach 60 km/h or above. The grinding wheels in rows are fixed to the rigid beam and are equivalent to asmooth surface and always make contact with wave crests, the stress lever of the grinding wheels in the horizontal direction is shorter, and the polishing and corrugation removing effect is better.
本发明涉及一种钢轨快速打磨车，包括打磨车车架（5），打磨车车架（5）底部装有前后两个转向架（4），前后两个转向架（4）之间装有打磨小车（6），打磨车车架（5）上部装有功能间（7），功能间（7）内装有吸尘装置（10）。本发明通过对钢轨进行低磨削量的预打磨及预防性打磨，能够有效扼制钢轨病害的萌发，大大延长钢轨的寿命及降低轮轨冲击噪声；通过采用被动式圆周磨削原理，能够实现双向行驶作业、多车重联，且打磨作业最高时速可达60km/h及以上。本发明将成排砂轮固定于刚性梁上，相当于一个平滑面，始终与波峰接触，砂轮水平方向受力杠杆更短，打磨去除波磨效果更优。
