Folding shed-type passageway structure used for locomotive

Abstract

The invention provides a folding shed-type passageway structure used for a locomotive. The folding shed-type passageway structure used for the locomotive comprises two sets of folding shed assembliesand ferry boards which are installed symmetrically. The ferry boards are installed below the folding shed assemblies. One end of each folding shed assembly is connected with the end face of a compartment, and the other end of the folding shed assembly is in contact with the opposite folding shed assembly. One end of each ferry board is connected with the compartment, and the other end of the ferryboard is in contact with the opposite ferry board. Each folding shed assembly comprises a butt joint plate and a shed cloth assembly, wherein the butt joint plate is installed at one end of the shedcloth assembly and is in butt joint with the opposite folding shed assembly, foamed rubber is pasted on the butt joint plate and is used for sealing a passageway, and the shed cloth assembly is in a compressed state and is used for making the two folding shed assemblies always in the compressed state. Springs are arranged in the ferry boards, so that the two ferry boards are always in a pre-tightened state. According to the folding shed-type passageway structure used for the locomotive, the folding shed assemblies and the ferry boards can always be squeezed by each other and make contact witheach other in the operating process of a vehicle, so that good airtightness of the passageway is achieved; and a train can be disassembled by loosing compartment connecting hooks, so that the maintenance time is greatly shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of locomotive manufacturing, in particular to a bellows-type through passage structure for locomotives. Background technique [0002] The through channel (also known as the windshield) is mainly installed at the joint of the adjacent rail vehicle ends to form a complete channel between the two cars. It should have good flexibility and can adapt to the requirements of the vehicle's running curve track, and has the vehicle end connection and safety protection. [0003] The locomotive needs to be decompiled and maintained frequently during use. After the common passage is connected, the connecting bolts or the sealing device need to be disassembled or the sealing device removed. The working time is long and the maintenance efficiency is low; the rubber windshield used by the rolling stock mainly includes rubber capsules and Lap-joint crossing boards; after adjacent carriages are hooked together, the capsules a...

Problems solved by technology

[0003] The locomotive needs to be decompiled and maintained frequently during use. After the common passage is connected, the connecting bolts or the sealing device need to be disassembled or the sealing device removed. The working time is long and the maintenance efficiency is low; the rubber windshield used by the rolling stock mainly includes rubber capsules and Lap-joint crossing boards; after adjacent carriages are hooked together, the capsules are squeezed and sealed with each other, and the crossing boards are randomly lapped to realize the docking function between vehicles

The rubber windshield has a simple structure and is convenient to hang, but there are problems such as poor sealing performance, short service life, high maintenance cost, interference between the crossing board and the end wall, and abnormal noise when the crossing board is running;
