High-speed EMU pantograph deicing carbon skateboard

Abstract

The invention discloses a high-speed-motor-train-unit pantograph deicing carbon sliding plate. The high-speed-motor-train-unit pantograph deicing carbon sliding plate comprises an aluminum bracket, a carbon strip and an L-shaped copper plate. The carbon strip and the L-shaped copper plate are fixed on the upper surface of the aluminum bracket, the L-shaped copper plate is arranged on one side of the carbon strip, a groove is cut in the bottom of one side of the carbon strip, the short edge of the L-shaped copper plate is located in the groove to allow one side of the carbon strip to press the L-shaped copper plate, the top of the long edge of the L-shaped copper plate and the carbon strip are located at the same height, and meanwhile an ADD air channel is formed inside the carbon strip. According to the high-speed-motor-train-unit pantograph deicing carbon sliding plate, due to the impact toughness and the good electrical conductivity of a copper material, the carbon strip and a copper alloy material in the carbon sliding plate structure are completely combined, the problem that when railway locomotives and high-speed-motor-train-unit trains suffer from rain and snow weather and greasy weather in all seasons, wires are iced, and running of motor-train-unit trains is influenced is well solved, the safe and normal running of motor train units is guaranteed, and serious pantograph net accidents caused by iced wires are reduced.

Description

technical field [0001] The invention belongs to the field of railway transportation, and relates to a special component for high-speed deicing that affects the operation of the EMU when the railway locomotive and high-speed EMU train encounter rain, snow and fog during winter operation. It is a high-speed EMU pantograph deicing carbon skateboard. Background technique [0002] At present, my country's high-speed rail is developing rapidly, and the technology of high-speed rail has reached the international leading level. Currently, the operating lines are constantly being built and opened to traffic, and they are also involved in the construction of foreign high-speed rail projects. In the 13th Five-Year Plan, the construction of my country's high-speed rail and bullet train lines is still the focus. [0003] Due to the vast territory of our country, the temperature and climate change greatly in four seasons, especially in autumn and winter, the north may start to snow in Oc...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a safe, stable and longer service life pantograph deicing carbon slide, which is used to solve the problem of ice formation on the wires when railway locomotives and high-speed EMUs encounter rain, snow and fog in various seasons. During the high-speed operation of the EMU pantograph, the carbon skateboard of the EMU will come into contact with ice on the wires, resulting in insulation contact and hard point impact, which will affect the safe and normal operation of the EMU, and will cause serious pantograph-catenary accidents
