Overhaul column of electrified railway catenary

Abstract

The invention provides an electrified railway contact network overhaul train. The electrified railway contact network overhaul train is composed of a first tractor, a plurality of work vehicles and a second tractor. The work vehicles are arranged between the first tractor and the second tractor, the first tractor, the work vehicles and the second tractor are all connected through folding wind shields, the tops of the work vehicles are respectively provided with a lifting work platform, and the lifting work platforms are communicated with one another after being lifted. The electrified railway contact network overhaul train is provided with the communicated work platforms, construction work can be performed on a contact network with the line range of 160 m at the same time, the functions of erecting lines of the contact network, maintenance, repair, high-altitude work and the like are integrated, multi-machine multi-work type cooperative work is achieved, a large amount of skylight time is saved, the electrified railway contact network overhaul train has the highest self running speed of 120 km / h and has the functions of transportation and storage of construction materials, machine maintenance and transportation and storage of tools and safety spares, and thus the construction site can have the workshop operation functions, the operating environment of workers is improved, and the operating precision is improved.

Description

technical field [0001] The invention belongs to the technical field of railway engineering machinery, and in particular relates to an electrified railway catenary maintenance train. Background technique [0002] In recent years, my country's railways have achieved leapfrog development. By 2020, the operating mileage of national railways will reach 120,000 kilometers. The rapid development has put forward higher requirements for the operation safety of railway power supply equipment. The good condition of electrified railway catenary is the basis for railway safety and high-speed operation. Therefore, higher requirements are put forward for the quality of maintenance of catenary equipment. The original It is difficult for work vehicles to adapt to the needs of electrified railway maintenance operations under the new situation. High-speed, high-efficiency and high-reliability catenary maintenance trains will surely become new requirements for electrified railway catenary mainten...

[0002] In recent years, my country's railways have achieved leapfrog development. By 2020, the operating mileage of national railways will reach 120,000 kilometers. The rapid development has put forward higher requirements for the operation safety of railway power supply equipment. The good condition of electrified railway catenary is the basis for railway safety and high-speed operation. Therefore, higher requirements are put forward for the quality of maintenance of catenary equipment. The original It is difficult for work vehicles to adapt to the needs of electrified railway maintenance operations under the new situation. High-speed, high-efficiency and high-reliability catenary maintenance trains will surely become new requirements for electrified railway catenary maintenance departments under the new situation. The work vehicle proposes improvements
