Through-long portal frame type three-dimensional maintenance operation platform for power centralized motor train unit

Abstract

The invention discloses a through-long portal frame type three-dimensional maintenance operation platform for a power centralized motor train unit. The through-long portal frame type three-dimensionalmaintenance operation platform is characterized in that the platform is used for retrofitting an existing passenger train servicing subdivision, and the platform comprises contact net wrist arms (2),portal frames (3), a protective net (4), a wrist arm mounting pillar (5), a rain-proof shed (7), a three-layer operation platform (8) and a two-layer operation platform (9); and the construction design is used for carrying out electrochemical net hanging on subdivision incoming and outgoing tracks, draw-out tracks and reconditioning station tracks with trenches and is used for finishing locomotive first-grade reconditioning, passenger car daily maintenance and the like in the 160 km power centralized motor train unit motor train D1 repair process; the manual operation difficulty can be effectively reduced, and the operation time can be effectively shortened; and meanwhile, a safety interlocking monitoring system is additionally arranged, so that the safety of the climbing operation of themaintenance personnel is guaranteed.

Description

technical field [0001] The invention belongs to the field of transformation of existing passenger whole stations and maintenance of power centralized EMUs, and in particular relates to a three-dimensional inspection and maintenance operation platform for long gantry type power centralized EMUs. 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 transportati...

AI Technical Summary

Problems solved by technology

[0004] At present, the inspection operation of the centralized power EMU is faced with the difficulty of the existing maintenance line of the passenger train station without catenary facilities, which cannot meet the running requirements of the centralized power EMU and the vehicle maintenance operation.

[0005] In addition, the structural parameters of the power concentrated EMU are quite different from those of the traditional EMU

If the new bullet train service station is used exclusively for its 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
