Cable assembly for power transmission of adjacent motor train unit carriages

Abstract

The invention relates to the technical field of power transmission, in particular to a cable assembly for power transmission of adjacent motor train unit carriages, which comprises a cable body, a mounting structure, a buffer structure, an adjusting structure, a clamping structure and a supporting structure, wherein the cable body can be fixed through the clamping and fixing structure, the fixingeffect of cables between adjacent carriages is ensured, the cable body can be conveniently mounted and taken out through the mounting structure, the efficiency of cable placement is enhanced, the cables between the adjacent carriages can be connected and fixed through the buffer structure, meanwhile, the cable is ensured to work normally under the stretching of the carriages, the maximum buffer distance of the buffer structure can be adjusted through the adjusting structure, the damage degree of the cable when the cable is excessively pulled is reduced, the bent part of the cable can be supported through the supporting structure, the cable can be ensured to be normally stretched, meanwhile, the stability of the cable in the stretching process is guaranteed, and damage to the cable due to shaking of a carriage is reduced.

Description

technical field [0001] The invention relates to the technical field of electric power transmission, in particular to a cable assembly for electric power transmission in adjacent train cars. Background technique [0002] EMUs, the full name of power vehicles, refer to vehicles equipped with power devices in the rail transit system, including locomotives and power carriages. The motor car is equipped with driving wheels, and the corresponding non-driving device vehicle is a trailer. In order for the train to run normally on the track, there must be a moving car to provide sufficient traction for the entire train, but it is not necessary to hang a trailer without power. An EMU is a railway vehicle equipped with wheel-driven machinery, not an EMU. Not only high-speed trains have moving cars, but all types of trains, including regular-speed EMUs, ordinary speed trains, subway trains, light rail trains, monorail trains and maglev trains, have moving cars. There are two categori...

AI Technical Summary

Problems solved by technology

[0003] Electricity transmission needs to be carried out through cables between the carriages of high-speed trains. When the cables are directly erected between adjacent carriages, due to the relative shaking or even small-scale stretching of adjacent carriages during driving, it may cause damage to the cables. Strain, long-term use may cause damage to the cable, and the cable will be twisted with the shaking between the cars, which may cause damage to the internal wires
