Air rail traction network

Abstract

The invention provides an air rail traction network, which comprises a copper-clad steel contact wire, busbars, a pressing plate, an insulating support piece and a connecting plate, the copper-clad steel contact wire is fixed at the front end of the busbar, the rear part of the busbar is connected with the adjustable insulating support piece through the pressing plate, the adjacent busbars are fixed through the connecting plate. The busbar and the connecting plate are connected through a countersunk bolt assembly, a counter bore is formed in the busbar, and a through hole is formed in the connecting plate. The continuous copper-clad steel contact wire is adopted as a contact surface to rub with a train current collector and transmit electric energy to a train, so that joint gaps generated by a steel-aluminum composite contact rail technology can be effectively reduced, collision sound generated when the current collector passes through a steel-aluminum composite contact rail joint is effectively reduced, and a contact net is convenient to install and adjust. Conductor current-carrying cross section requirements are saved, engineering investment is saved, and the pantograph-catenary relation is improved.

Description

technical field [0001] The invention belongs to the field of rail transportation, in particular to an empty rail traction net. Background technique [0002] In recent years, a variety of low-volume rail transit systems have flourished in my country. In 2016, the first domestic empty rail (air rail) test line jointly built by Zhongtang Air Railway and Southwest Jiaotong University was completed and opened to traffic in Chengdu. Subsequently, Qingdao Sifang and China Railway Science and Technology also successively built empty rail test lines. Compared with ordinary urban traffic systems, empty rails pass through; pier columns are erected in the air, occupying a small area, generally occupying the urban isolation belt, reducing the amount of demolition and relocation as much as possible, and will not occupy the original traffic space of the city, especially Under the premise of the existing urban traffic layout, when ground and underground transportation facilities such as li...

AI Technical Summary

Problems solved by technology

Regardless of the connecting part of the C-shaped contact rail or the I-shaped contact rail, there are joint gaps. Regardless of its shape or installation position, when two steel-aluminum composite rails are cut and installed, there are always uneven joints, In the case of not being closely attached, the current collector is not stable when passing through these gaps, and there is a possibility of scratching the current collector at the speed of the train.

[0007] 2. Noise problem: When the current collector passes through these seams, it will produce a "clang clang" collision sound, which will eventually form a regular collision sound similar to the old-fashioned train wheels passing through the rail seams

[0008] 3. Difficulty in installation: the rigidity of the steel-aluminum composite contact rail is very high, and it is very difficult to install and adjust when it is used under a small curve radius
