| 摘 要： | 传统列车运行达到一定的走行公里或年限后，机车和车辆需从各铁路局分别送到机车、车辆制造工厂进行（大）厂修，待修机车车辆在铁路局与机车车辆制造工厂之间往返过程中有占用铁路通过能力、干扰正线运营、检修周期长的弊病，动车组价格昂贵要求停修时间尽量缩短，因此需要研究设计厂修、段修合一的动车组检修基地即动车段.动车段的工艺设计要求兼容不同类型动车组检修，且动车段检修效率要高.为了解决上述问题，研究了厂修、段修合一的动车段总平面布局方案和段址方案，以及CRH2型、CRH3型动车组三级修（段修）的地坑式架车机方案，并研究了四、五级修快速完成1节车检修的流水检修方案.根据研究设计的方案，实现了厂修、段修房屋组合；使CRH2型、CRH3型动车组三级修（段修）地坑式架车机的架车单元在17.375~17.500 m范围连续可调，实现了CRH2型、CRH3型三级修兼容，一条检修线检修两组8辆编组的动车组，又能检修16辆固定编组动车组；并实现了四、五级修每80 min完成1节车检修，各检修工位工序专业化检修，避免了各检修专业组间交叉作业，保证车体部件组装工位环境清洁，提高了检修效率和质量.

| Abstract: | Conventional locomotives and vehicles need to be transported to locomotive and vehicle manufacturing factories for large repair or overhaul from railway bureaus after they have attained a certain traveling mileage or run a certain number of years. Transporting locomotives and vehicles between railway bureaus and manufacturing factories for repair wastes the carrying capacity of railway lines, interferes with railway operation, and extends maintenance time. Besides, the maintenance time of EMUs needs to be minimised because of the high cost of EMUs. In summary, an EMU maintenance base (EMU depot) that combines overhaul and depot repair needs to be investigated. The process design of an EMU depot needs to be compatible with the maintenance of different types of EMUs, and the efficiency of the EMU depot needs to be improved. In order to solve the abovementioned problems, the general layout scheme and choice of land block of the EMU depot are studied. In addition, a scheme of underfloor vehicle-lifting machines for CRH2 and CRH3 EMU level 3 maintenance (depot repair) is studied. Finally, the efficient completion of a successive maintenance scheme for level 4 and 5 maintenance of a vehicle is presented. According to the design scheme presented herein, the combination of the overhaul and depot repair is first realised. In addition, the length of the vehicle-lifting elements of the machine can be adjusted within a range of 17. 375-17. 500 m, which achieves compatibility with the level 3 maintenance of CRH2 and CRH3 EMU. Further, the designed maintenance line is applicable to not only two eight-car EMUs but also a 16-car EMU. Moreover, level 4 and 5 maintenance of a vehicle can be completed within 80 min. With the proposed scheme, the specialisation of every maintenance station and process can be realised. The cross operation among different maintenance groups is avoided. A clean assembly station of car body parts is guaranteed, and maintenance efficiency and quality are improved. |
