Rapid boarding and alighting system for vacuum pipeline maglev train

Abstract

The invention relates to a rapid boarding and alighting system for a vacuum pipeline maglev train, and belongs to the technical field of rail transit. The system comprises a fixed channel and a movingchannel, a sealing isolation door is installed at a platform passage port, the moving channel is provided with a connection port, and the bottom of the moving channel is supported on a ground rail through rollers and connected with a translation driving device; the port of the connection port is provided with a butt joint sealing ring, and the two sides of the connection port are provided with drag hook type locking mechanisms; the fixed channel and the movable channel are connected in a sealed mode through sealing tarpaulin. The sealing isolation door is provided with bearing wheels supported on the door carrying rails, jacking cylinders are installed at the positions of the bearing wheels, and the front ends of telescopic push rods of the jacking cylinders directly face the sealing isolation door. By adopting a series of comprehensive sealing measures, the vacuum degree of the vacuum pipeline is reliably kept, the running performance of a train is guaranteed, and the sealing isolation door is isolated from the sealing pressing acting force at the two ends of the train outer door, so that the sealing isolation door and the train outer door do not interfere with each other, and the sealing effect can be kept.

Description

technical field [0001] The invention relates to a device for fast loading and unloading of trains, in particular to a system for fast loading and unloading of vacuum pipeline maglev trains, belonging to the technical field of rail transit. Background technique [0002] Air resistance is the fundamental reason that limits the maximum economical speed of ground transportation on the platform. Trains running in vacuum tubes combine maglev train technology and low-pressure tube technology, which can get rid of the shackles of the dense atmosphere on the surface and minimize the time when the train runs at high speed. Excellent frictional resistance and aerodynamic resistance to achieve ultra-high-speed transportation. Since the vacuum pipeline is in a vacuum state, and the carriages inside the pipeline and the platform outside the pipeline are in a standard atmospheric environment, the key problem to be solved for passengers getting on and off the train is to cross the vacuum zo...

Problems solved by technology

[0003] At present, there are mainly two types of train connection schemes: one is that the vehicle enters the normal pressure environment through the air pressure transition chamber to complete the passengers' boarding and disembarking. Vacuum) and independent space to accommodate the train, which occupies a large volume, high infrastructure and operating costs, and takes a long time; the other is that the vehicle is parked in a vacuum environment, and the carriage is connected to the platform through a well-sealed connecting transition passage, and passengers pass through it. Get on and off the car, this method occupies a small space, low operating costs, and is easy to commercialize

[0004] According to the applicant's understanding, the design of the existing connecting structure fails to properly solve two major problems: 1) The docking structure needs to accurately align the outer door of the train with a parking error of centimeter level after the train stops, and lacks a reliable locking device; 2) The docking structure It is difficult to reliably isolate and seal the rear of the car body from the surrounding low vacuum environment

The research shows that its disadvantage is that the sealing effect of the curved surface of the O-shaped rubber ring seal is not good, the accuracy of the curved butt joint cannot be guaranteed, and there is no solution for the up and down deviation of the butt joint, so the sealing effect cannot be guaranteed; in addition, the interface adopts magnetic attraction to provide sealing force , it is necessary to add magnetic material on the train body as a docking pair, which increases the load of the train and reduces the carrying capacity
