A rail vehicle car end cable cross-over structure

Abstract

The cable crossover structure at the vehicle end of the rail vehicle provided by the present invention has a mounting bracket fixed on the coupler. The mounting bracket has a first support plate located in the middle of the two vehicles and arranged along the transverse direction of the vehicle, and is separately arranged on both sides of the first support plate facing The second support plate and the third support plate of the rail vehicle, the upper surface of the first support plate and the upper surface of the second support plate are provided with the first wire clip assembly, the lower surface of the first support plate and the lower surface of the third support plate A second wire clamp assembly is arranged on the surface, and the train jumper wires on both sides at the end of the vehicle are crossed by the first wire clamp assembly and the second wire clamp assembly and are independently arranged up and down. The structure of the invention enables cables to be cross-connected to solve the problem of different types of double-group vehicles; the invention can be used on intermediate vehicles that need to be bridged in any even-numbered group of vehicles by adjusting the clamping block to ensure the same type of vehicle.

Description

technical field [0001] The invention relates to a rail vehicle cable crossover structure, and belongs to the field of rail vehicle vehicle end bridge design. Background technique [0002] The vehicle bridge structure is an integral part of the multi-unit rail vehicle. [0003] At present, the cross-connection methods used in domestic multi-group vehicles are mostly internal cross-connection in the middle vehicle, and the same-side cross-connection structure in the middle of other vehicles. This kind of bridge structure uses two different junction box structures of intermediate cars to complete the bridge first, and then use the same side bridge structure as other vehicles to realize the bridge. This jumper method can keep the length of jumper wires consistent between vehicles. However, intermediate vehicles need to use different models or junction box structures to meet the crossover requirements. Especially for double-marshalling vehicles, if the above method is used to ...

AI Technical Summary

Problems solved by technology

Especially for double-marshalling vehicles, if the above method is used to bridge, it is necessary to make two different vehicle structures or junction box structures, which will waste more design resources

[0004] After searching, it is found that the Chinese invention patent application CN201611087848.8 proposes a jumper cable installation structure on the roof of urban rail vehicles, which is mainly a same-side jumper structure, which cannot solve the problems in the background technology
