Three-dimensional maintenance operation platform for head car of power centralized motor train unit

Abstract

The invention discloses a three-dimensional maintenance operation platform for a head car of a power centralized motor train unit. The three-dimensional maintenance operation platform is characterizedin that the three-dimensional maintenance operation platform is used for transforming an existing servicing shed and a station track of a passenger train servicing subdivision, and comprises an operation platform vertical column (1), a catenary cantilever (2), a catenary cantilever vertical column (3), a protective network (4), a protective network vertical column (5), a front and read head car two-layer operation platform (6), a front and rear head car three-layer operation platform (7) and a rainproof shed (8); the head car of the power centralized motor train unit is maintained by using existing facilities of the existing passenger train servicing subdivision, the requirements of the top maintenance operation of the power centralized motor train unit are met, and the cost is saved; thethree-dimensional maintenance operation platform can be applied to the head car, and also can be suitable for the use of trailer in the middle part, the adaptability is high, and all maintenance needs under the condition of saving construction costs and shortening construction cycle are met.

Description

technical field [0001] The invention belongs to the field of transformation of existing passenger whole stations and maintenance of power centralized multiple train units, and in particular relates to a three-dimensional maintenance operation platform for head cars of power centralized multiple train units. Background technique [0002] At present, railway passenger trains are mainly divided into EMUs (power distributed type) and ordinary speed passenger trains. In order to meet different market demands, the "Fuxing" Chinese standard EMU series is being developed, and the standard EMU will form a standard series of products with speed grades of CR400 / 300 / 200, of which the CR200 grade standard EMU will gradually replace ordinary speed passengers. bus. [0003] Power-concentrated EMUs, as a series of products of the "Fuxing" EMUs, play an important role in the upgrading of speed-increasing passenger cars, promoting the structural reform of the supply side of railway passenger...

AI Technical Summary

Problems solved by technology

[0005] 1. There is no catenary facility in the existing maintenance line of the passenger train station, which cannot meet the running requirements of the power-concentrated EMU and the requirements of vehicle maintenance operations

[0006] 2. The structural parameters of the concentrated power EMU are quite different from those of the traditional EMU. If the new EMU is used exclusively for maintenance, the project investment will be large, land acquisition will be difficult, and the construction period will be long

If it is towed to the passenger vehicle station for maintenance and maintenance by engineering dispatching machines, the maintenance facilities of the passenger vehicle station cannot meet the requirements of power centralized EMU maintenance, summit maintenance, and car storage

If a new maintenance operation platform of the existing type is built, the scale will be large, the cost will be high, and the construction period will be long
