RT轨道交通是什么部门

what is behind cbtc？ and how can it improve metro services？ cbtc means communications based train control with cbtc you have the possibility to optimize various aspects of your mass transit network including capacity， punctuality， safety and energy efficiency let's take a look at how this works unlike the conventional fixed block system where train spacing is identified by the rail system trains continuously communicate their status via radio to the wayside equipment along the line so trains continuously receive information regarding the distance to the proceeding train adjusting the safety distance accordingly due to this dynamic detection via the real moving block operation concept shorter headways between trains are possible headways of ninety seconds are less meaning more trains on the line maximizing capacity due to the optimized braking distances we achieve energy savings of up to twenty percent remote connectivity and monitoring provides you with the improved insight into services and network condition another advantage with our cbtc system is that it is able to operate in mixed traffic environments and different train types therefore it allows easy migration of existing networks to improve the performance so what does this technology mean for both the rail operator and the passenger it means maximum reliability， safety and availability enabling one hundred percent punctuality of services with cbtc you get a system that allows you to flexibly and efficiently upgrade your rail operations in all aspects of mass transit。

哈喽，大家好，我是一条货车轮队，我走过南，闯过北，今天我有些疲惫，听说今天是我体检的日子，让我们来看一看我要体检哪些项目吧， 晚上见啊兄弟，我们要暂时分开啦，我们去体检啦， 看前面那台就是为我测量各项数据的机器。 第一道体检结束啦，接下来我要去洗个澡啦，你们别偷看哦， 洗完澡干干净净耶，前面那个黑屋子是干什么的，不要把我推进去啊，我怕。 我们泰山组的工序主要有四道工序，第一就是人类的清洗，清洗合格的话进行人类的洗碗烫伤第二步，第三步是离人类的危机烫伤 啊，第四步应该是人类的超人波塔山。手工超人波塔山。哦，原来这只是一个体检的项目啊，总觉得自己最近有些胖，让我来减肥瘦身一下吧。 减肥完成了，接下来可以把轴承盖子还给我了吧， 测量、压端，磨合，今天的体检结果好像还不错哦， 谢谢工人师傅们的辛勤劳作，谢谢你们的努力，我一定会跑的又快又稳，保障咱铁路货运的畅通。

l 型列车是什么？ l 型车不是按车辆规格划分出的一个车型，而是为直线电机车单独划分的一个车型。 l 型车为直线电机驱动轨道导向的中运量城市轨道交通系统，因为用的是直线电机，所以不能与传统的城市地铁交通通用， 所以 l 型列车服役的线路不多。这种车型一般适用于两种情况，一是因为地质地貌所限，急需解决大坡度、小半径问题的线路。二是城市的郊区线、机场线、观光线。 直线电机传动是利用直线电机和轨道中间安装的感应板之间的电磁效应产生的推理作为列车的牵引力和电池动力，此牵引力或电池动力与轮轨之间的粘着关系无关，因此列车的爬坡能力远 大于采用旋转电机的车辆。 l 型列车长十六点八米，宽二点八米，目前只有北京跟广州运行有此车。北京有两条线路采用北京地铁首都机场线，采用四节编组 l 型列车定员二百一十八人，最高时速可达一百一十千米每小时。 建设中的北京地铁二十八号线则采用六节编组 l 型列车。广州有三条线路采用 l 型列车，为广州地铁四号线、五号线、六号线，其中四号线和六号线采用四节编组 l 型列车，五号线则采用六节编组 l 型列车。 错过广州这三条线路的小伙伴应该知道这几条线路有多么拥挤了。以上就是目前国内所有采用 l 型列车的线路了，感谢各位的收看！

列车驶入架修库进行有电和无电预检， 通过委外人员对车下清洁后，列车进入驾车道，准备驾车结编。 固定式驾车机的举身单元将列车举起， 方便检修人员在车底进行拆装作业。转向架与车体分离后推入工艺转向架通过浅坑式移车台进行分离。移车 通过单梁桥式起重机将受电工空调调离车顶，再通过平板顶升 agv 将车顶设备自动运输至空调受电工存放处。 车下部件通过液压小车、叉车、 ajv 悬臂吊等工装进行拆除，运送至加以缓解。 转向架检修通过悬挂式构架检修线，最大程度上实现自动化作业及数字化管理。转向架需要经过轮对构架分离、部件拆解、构架清洗、构架检修、部件安装以及轮对构架组装，最后进行转向架进载实验。 自动管路保压实验完成空滑安装。 车门检修主要包含车 车门贯通到以及客室内装的检修。 轮队检修是对轮队轴箱、轴承进行检修，需要通过轮队自动化输送线对轮队进行轴端拆卸、轴箱拆卸、轴承退卸、 轮对清洗脱漆、荧光磁粉碳伤、超声波碳伤、轮对尺寸测量、悬轮轮对喷漆、轴承压桩、轴端安装、轴箱安装。 最后组装好的轮队通过跑核实验完成轮队检修。 电气检修以功能测试为主， 同进更新轴承受流线和易损易耗件，其中接触器单元设备所用实验装置为珠江路车辆架大修中心自主研发装置，可提高工作效率，提高安全性能。 转向架轮队完成检修后运送至落车工位，完成列车上下体组装以及落车前的准备工作。 通过固定式驾车机举身单元完成落车工作。 工程车将列车牵引至进条库内，通过通电前检查静态调试，再进入试车线完成动态调试。 至此，整个列车的驾修历程就结束了。胆劲尘埃华光灿，别有天地春风来。从理想走向强大需要一种勇气， 从平凡走向辉煌需要一种锐气。珠江路车辆架大修机里将秉承勇于开阔、锐意进取的理念，始终在攻坚克难第一线服务群众最前沿。

the rail expansion joint also known as switch expansion joint it is used in railway tracks at the end of long welded rails fitted to the slippers the term rail expansion joint and switch expansion joint are alternatively used in railway in this video we will learn the rail expansion joint and tongue rail rail joint is a track component that connects two pieces of rail and it provides room for rail expansion and contraction due to the changes in temperature in rail terminology a fish plate splice bar or joint bar that is bolted to the ends of of two rails to join them together in a track let's see a joint expansion working cycle the switch expansion joint is used to take the expansion in a long welded rail， it is connected to long welded rails only on one side or both sides switch expansion joint depends on temperature variation during the daytime and also throughout the year depending upon the season there are two rails namely a stock rail and a tongue rail one sliding against the other both these rails are running rails tongue rails lie between the two stock rails supported on sliding plates and connected by stretcher bars near the toe and both the tongue rails heel block inserted between the heel of tongue rail and stock rail it provide the a clear gap for the wheel flange。

啊啊啊。

电子制动控制单元根据空气弹簧压力数据计算各节车厢的实时重量，可以计算出每一节车厢满足刹车指令要求而需要的制动力。 电子制动控制单元把制动力数据分配给每一节车厢的气动制动控制单元。气动制动控制单元由 ep 阀、中计阀和其他部件组成。 ep 阀是气动制动单元的核心部件之一，由进气阀、排气阀和传感器组成，跟一个眼镜盒差不多大小。它的作用是根据接收到的电信号指令精准调节和输出少量压缩空 空气，用来控制下游气动制动元器件工作。

railway adjustment switch is a part of switch expansion joint in this video we will learn the working of adjustment switch adjustment switch is device that permits the longitudinal movement of rails caused due thermal expansion and contraction switch expansion joint the design has been modified to overcome the defects caused by band and also reduce the maintenance cost on the railway track the adjustment switches are placed between the continuous welded rail cwr and jointed track or cwr and s and c， it is also used on metallic bridges over 30 meters length these switches are design time to move only on the cwr side so that the joint gaps provided on the jointed side can adjust to the thermal expansion the rail is supported with the clamp plate lay over the cast iron chair or base plates with the help of bolts switches must have a pair of rail straps attached to the bearers switches are aligned squarely between the rail tongs throughout the normal direction of the traffic flow there is a minimum 60 millimeters of the rail tips which is supported by the base plates and lie within the clamp plates the four rail section must be supported by the base plates and lie within the clamp plates by a minimum of 30 millimeters the working of adjustment switch is very simple due to the thermal expansion the jointed side can adjust automatic。
