Abstract

The invention discloses a single-pipe double-line maglev traffic vacuum pipeline with a sealing door, which comprises a vacuum pipeline, the vacuum pipeline is divided into two driving channels from the middle by a wind shield, a driving motor and a sealing fan are also arranged in the vacuum pipeline, one side of the sealing fan is hermetically connected with the wind shield, and the other side of the sealing fan is hermetically connected with a swing rod; the oscillating bar is in power connection with the driving motor, and a first clamping and sealing device and a second clamping and sealing device are further arranged in the vacuum pipeline, so that the bottom and the top of the sealing fan are completely sealed; compared with the prior art, the structure characteristics of a single-pipe double-line vacuum pipeline are combined, the sealing fan is unfolded and folded in a swing rod swing mode, the corresponding mechanical structure is greatly simplified, the equipment size is reduced, damage to the integrity of the vacuum pipeline is avoided, the structural strength of the vacuum pipeline is improved, and the service life of the vacuum pipeline is prolonged. Meanwhile, the space occupied by equipment is reduced, the influence on the blocking ratio is avoided, and the dynamic performance of the vehicle is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of rail transit equipment, in particular to a single-pipe double-line maglev transportation vacuum pipeline with a sealed door. Background technique

[0002] Speed ​​has always been a goal of human beings in the development of transportation. Traditional wheel-rail trains have limited space for speed improvement due to factors such as wheel-rail adhesion coefficient and air resistance. Therefore, maglev trains with low noise and high-speed operation are gradually being accepted Follow and research. When the maglev train runs at a high speed in the open wire environment, it will also be troubled by serious aerodynamic problems. Therefore, the vacuum tube high-temperature superconducting maglev transportation system with the characteristics of low resistance and self-stable suspension came into being. .

[0003] In order to ensure the low-resistance operation of the pipeline train, the air pressure in the pi...
