An anti-icing multi-roller rigid contact current receiving device

Abstract

An anti-icing multi-roller rigid contact current receiving device is composed of a "T"-shaped rigid contact net and a deicing current receiving mechanism. It is formed on a U-shaped integral bracket; the deicing and current-receiving mechanism is: the left and right sides of the upper surface of the lower deicing blade are respectively provided with front and rear deicing blades with the same shape and structure, and two or more current-receiving rollers, each receiving current. The drum of the drum is fixed on the main shaft through two bearings. The bottom of the main shaft is movably inserted into the limit ring, the limit shaft fixed on the bottom surface of the main shaft forms a rolling fit with the bottom surface of the blind hole of the limit ring, elastic mechanisms are respectively provided on both sides of the drum main shaft, the invention can effectively remove ice on the contact net in real time, It has the advantage of ensuring that the electrician can receive the current stably.

Description

technical field [0001] The invention relates to the technical field of electrified railways, in particular to a novel anti-icing multi-roller rigid contact current receiving device. Background technique [0002] Catenary, as a unique structure of electrified railway, provides traction current for electric locomotives and ensures the reliable operation of electric locomotives. The overhead catenary is divided into rigid catenary and flexible catenary. In special working conditions such as tunnels, a rigid catenary structure is often used. If the air humidity in the tunnel is high and the temperature in the tunnel is low, the rigid catenary will form. icing. If there is water seepage in the tunnel, the water will flow through the rigid catenary, and ice will also form in low temperature climates, and the traditional "I" structure will make the rigid catenary form larger ice cubes when the ice is severe, and the rigid contact The icing of the grid will cause poor contact with...

AI Technical Summary

Problems solved by technology

[0004] At present, the construction of high-speed railways in various regions is on the rise. Some high-speed railway lines will inevitably pass through low-temperature, high-humidity, high-altitude and other areas. In these low-temperature and ice-covered tunnels, if the traditional rigid catenary flow collection method is still used, it will be difficult to ensure the reliable flow collection of the EMU
