LRG型钢轨打磨车 Model LRG rail grinding machine
该车是由2辆液压传动的8磨头打磨车组成,通过刚性牵引杆连接组成16磨头打磨车组。两车均自带动力系统,在结构上基本对称布置,动力源为内燃柴油机,配备大功率发电机组为打磨装置供电,静液压传动走行。
This machine is composed of two hydraulic driven grinding cars with 8 grinding heads respectively, and composes a grinding car group with 16 grinding heads through connection by rigid drawbar. Both of the two cars have self-equipped power system and are arranged symmetrically in structure. The power source is from internal combustion diesel engine, and high-power generator unit is provided for supplying power to the grinding device, and traveling is realized by hydrostatic driving.

适用于标准轨距地铁线路的钢轨打磨作业,能在低恒速运行过程中利用电机驱动高速旋转的砂轮对钢轨轨头表面进行磨削,恢复钢轨横断面轮廓形状、提高钢轨的纵向平顺性、可消除钢轨表面锈蚀、疲劳裂纹、波浪、磨损、变形、斑点、飞边等缺陷,延长钢轨寿命。
It is applicable to rail grinding of standard gauge metro line, and able to grind the rail head surface by means of high-speed rotating grinding wheels driven by motor during operation at low constant speed, recover the contour shape of rail cross section, improve the longitudinal smoothness of rail, eliminate the defects such as rail surface corrosion, fatigue cracks, corrugation, wear, deformation, speckles and fins, and prolong the service life of rail.
