Technical Field

The utility model relates to a quick passenger getting on and off device of train, concretely relates to be used for quick passenger getting on and off system of vacuum pipeline maglev train belongs to track traffic technical field.

Background

The air resistance is the root cause for limiting the highest economic running speed of the platform ground traffic, the magnetic suspension train technology and the low-pressure pipeline technology are combined in the train running in the vacuum pipeline, the constraint of dense atmosphere on the ground surface can be released, the friction resistance and the pneumatic resistance of the train running at high speed can be reduced to the maximum extent, and the ultra-high speed transportation is realized. Because the vacuum pipeline is in a vacuum state, and the carriage in the pipeline and the platform outside the pipeline are in a standard atmospheric environment, the key problem to be solved for passengers to get on or off the train is to pass through a vacuum zone between the platform and the carriage, namely, a stable transition passage with standard atmospheric pressure is constructed in the vacuum environment.

At present, the connection scheme of the train mainly has two types: firstly, the vehicle drives into the normal pressure environment through the air pressure transition cabin to finish the getting on and off of passengers, the scheme needs a large amount of air charging and discharging equipment to realize the conversion of air pressure (air ventilation in the station and vacuumizing in the station) and an independent space to accommodate the train, and the scheme has large occupied volume, high capital construction and operation cost and long consumed time; the other is that the vehicle stops in a vacuum environment, the carriage is connected with the platform through a well-sealed connection transition channel, and passengers get on or off the vehicle through the channel.

According to the applicant, the design of the existing connection structure cannot properly solve two problems: 1) the butt joint structure needs to be accurately aligned with a centimeter-level train outer door with a stop error after a train stops, and a reliable locking device is lacked; 2) and reliable isolation and sealing between the butt joint vehicle body and the surrounding low vacuum environment are difficult to ensure.

The retrieval shows that the Chinese patent application with the application number of 201711087916.5 discloses a connecting device for a station and a high-speed train carriage in a vacuum pipeline, which is a composite device jointly constructed by a channel, a channel door, a system isolation film sleeve, a positioning column, mechanical power equipment and auxiliary structures; the device can connect and communicate the station normal pressure system with the train carriage normal pressure system of the vacuum system in the vacuum pipeline, so that passengers can safely walk out of the carriage, enter the station or walk into the carriage from the station without destroying the vacuum degree in the vacuum pipeline. The sealing door of the technical scheme is arranged on the inner side of the channel, the inner side door occupies the inner space and is not favorable for walking, maintenance is not easy, and the sealing requirement is also improved; the inner part of the two doors is not subjected to re-pressing treatment, and the excessive pressure difference between the inside and the outside causes strong suction force and difficult door opening; the streamline of the train body is damaged, and the aerodynamic resistance and the wind noise during the train running are adversely affected.

In addition, chinese patent application No. 201810224890.2 discloses a vacuum connection system for vacuum pipeline maglev trains, including a transition cabin, a corrugated metal pipe and a butt-joint frame, the front end of the transition cabin is provided with a sealed cabin door, the rear end of the transition cabin is connected with one end of the corrugated metal pipe, the other end of the corrugated metal pipe is connected with the butt-joint frame, the butt-joint frame is used for butt-joint with the maglev train, a telescopic passage is arranged in the corrugated metal pipe, one end of the telescopic passage is connected with the butt-joint frame, the bottom of the transition cabin is provided with a telescopic passage chute, the other end of the telescopic passage is arranged in the telescopic passage chute, an electric cylinder is connected between the transition cabin and the butt-joint frame, the electric cylinder drives the butt-joint frame to move along the telescopic chute, the corrugated metal pipe moves. Research shows that the defects are that the curved surface sealing effect of the O-shaped rubber ring seal is poor, the curved surface butt joint precision cannot be guaranteed, and the up-down deviation of the butt joint position has no solution, so the sealing effect cannot be guaranteed; in addition, the magnetic attraction is adopted for the interface to provide sealing force, and a magnetic substance is required to be added on the train body to serve as a docking pair, so that the load of the train is increased, and the carrying capacity is reduced.
