Description

Technical Field

[0001] The invention belongs to the field of existing passenger maintenance depot reconstruction and centralized power EMU maintenance, and specifically relates to a full-length gantry type three-dimensional maintenance operation platform for centralized power EMUs. Background Art

[0002] At present, railway passenger trains are mainly divided into EMUs (distributed power) and ordinary passenger trains. In order to meet different market demands, the "Fuxing" China Standard EMU is being developed in series. The standard EMU will form a standard series of products with speed levels of CR400 / 300 / 200, among which the CR200 standard EMU will gradually replace ordinary passenger coaches.

[0003] As a series of products of the "Fuxing" EMU, the power-concentrated EMU plays an important role in upgrading the speed-up passenger cars, promoting the structural reform of the supply side of railway passenger transportation, and improving the efficiency of transportation organization. Compared with the traditional "locomotive + vehicle" ordinary speed train, the power-concentrated EMU adopts a non-disassembly operation mode, reducing the time for disassembly, end change and other operations, and adopts a fixed locomotive and vehicle formation and integrated maintenance mode.

[0004] At present, the inspection work of centralized power EMUs faces the difficulty that the existing maintenance lines in passenger maintenance depots have no overhead contact network facilities, which cannot meet the running requirements of centralized power EMUs and vehicle maintenance work.

[0005] In addition, the structural parameters of the centralized power EMU are quite different from those of the traditional EMU. If a new EMU operation depot is built for its maintenance, the project investment will be large, land acquisition will be difficult, and the construction period will be long. If the engineering shunting locomotive is used to haul the passenger maintenance depot for maintenance and maintenance, the maintenance facilities of the passenger maintenance depot cannot meet the requirements of the centralized power EMU maintenance, top maintenance, and storage. Summary of the invention

[0006] In view of at least one of the above defects or improvement requirements of the prior art, the present invention provides a three-dimensional maintenance operation platform for a full-length gantry-type power-concentrated EMU. According to the needs of adaptive transformation, in order to meet the requirements of climbing to the top for maintenance of power-concentrated EMUs and save the space of the maintenance passage between tracks, the present invention provides a three-dimensional maintenance operation platform for a full-length gantry-type power-concentrated EMU, which can electrify and network the tracks for preparing trenches and pulling out the lines, and is used to complete the first-level preparation of locomotives and daily maintenance of passenger cars in the D1 maintenance process of 160 kilometers of power-concentrated EMU power cars.
