城市轨道交通钢轨的高速维护;High Speed Maintenance for Rails 城市轨道交通钢轨的高速维护;High Speed Maintenance for Rails 城市轨道交通钢轨的高速维护;;High Speed Maintenance for Rails 城市轨道交通钢轨的高速维护;;Corrugation 波磨 （北京地铁6号线）;8;Linie 6 gemessen 0,25 mm! 波磨深度0.25 mm;To produce big smock 产生烟尘较大（烟雾和粉尘） Can be harming the health of workers 会影响作业人员健康 Rails cleaning 轨道清洗(金属粉尘堆积可能导致绝缘接头失效) Working noise 作业噪音 ;11;12;Rail defect: Headcheck 钢轨病害：鱼鳞纹Defect development 钢轨病害的发展过程;14;15;High speed grinding 高速打磨? ; work speed作业速度HSG-2: 80km/h HSG-City: 60km/h scope of grinding between打磨范围: +45°-- -70° amount of once grinding单次打磨量: 0.01-0.02mm rail surface roughness after grinding打磨后轨面粗糙度：8 μm dust recovery over 90%, don’t need to clean the track灰尘回收率：90%以上, 无需清洗道床 noise emissions 作业噪音排放：65-85db low production cost 生产成本低 （无动力） no need to remove the signal device无需拆卸线路信号装置,如计轴器 easy transportation of changing grinding line (no need transition line)转线运输方便（无需渡线） much flexible (with different tractors)作业组织灵活 （连挂不同牵引车：轨道车、公铁两用车）;18;;20; ;HSG-City ;HSG-City ;HSG-City ;25;Passive driven grinding stones 被动驱动砂轮 Passive adaptation to rail cross profile 被动适应钢轨横向廓形 Optimization of longitudinal profile 纵面廓形最优化 Constant material removal 恒定的磨削量 High working speed 高打磨作业效率 Over heating of rail impossible 避免钢轨过热 ;High Speed Grinding is designed to work as a regular train 将打磨车视作一辆正常行驶的列车，边行驶边打磨 No track preparation, e.g. dismantling of track installations like axle counters 打磨前无须拆除轨道装置，如：计轴器 No extra work after grinding, e.g. cleaning of insulated rail joints 打磨作业后没有额外的工作，如：清理绝缘接头 （作业后无需清洗轨道） No safety preparation of the track and safety personal required 没有特殊的安全防护要求，不需要设置现场防护员 Changing of grinding consumables from inside of the machine 在打磨车内部更换磨石 Neighbouring tracks keep running regular traffic 相邻轨道可保持常规的运营状态 Higher flexibility in planning of grinding work 更灵活的安排打磨计划。 Less traffic disruption and more effective use of track possession 更少干扰正常运营与更高的打磨效率 ;Grinding done with HSG-Light machine 应用高速打磨车—轻型，进行打磨作业 Noi
