DGM-16型钢轨打磨车(混合双动力) Model DGM-16 rail grinding machine (hybrid dual-power)
DGM-16型混合动力钢轨打磨车适用于标准轨距线路的钢轨打磨作业。该车由两节车(A车+B车)通过刚性牵引杆连接组成,整车动力来源于地铁接触网电能和自带内燃发电机组,两种动力均可驱动整车走行及打磨作业。
Model DGM-16 hybrid power rail grinding machine is applicable to rail grinding of standard track gauge line. This machine is composed of two cars (A car + B car) which are connected by rigid drawbar, and the power source for the complete vehicle is from the metro OCS electric energy and self-contained internal combustion generator unit. Both of the two power sources are able to drive the complete vehicle traveling and grinding.

该车利用先进的计算机网络控制技术,通过对打磨机构及整车的控制,实现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。
Based on advanced computer network control technology, and through control of the grinding mechanism and the complete vehicle, the machine is 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.
