Problems solved by technology

Although this technology simplifies the structure, it still has the following defects: (1) This technology uses a complex mechanical structure such as a hydraulic telescopic mechanism or a rack and pinion telescopic mechanism to drive the telescopic corridor to move, and the friction is large. If it is pushed by hand, it will greatly improve Labor intensity, if electric or other methods are used, will also increase energy consumption; (2) This technology uses platform personnel to control the movement of telescopic corridors. Need to configure personnel to open, waste manpower and increase cost

Embodiment 1

[0026] Such as Figure 1~Figure 4 Shown: a vacuum train air barrier entry and exit device, including a vacuum pipeline 1 and a train 2 located in the vacuum pipeline 1, the vacuum pipeline 1 is connected with a fixed passage 3, and the fixed passage 3 is provided with a tunnel door 4; One end is connected with a telescopic air baffle 5; a sliding structure is provided between the air baffle 5 and the fixed channel 3 to facilitate the movement of the air baffle 5. The sliding structure is a ball mechanism.

[0027] This embodiment has the following advantages: (1) the fixed channel and the air shield are arranged on the vacuum pipeline instead of the train, which can reduce the weight of the train and simplify the structure; (2) it is easy to manufacture and install, and the installation is more firm; (3 ) The tunnel door is moved outwards and installed on a fixed channel, which simplifies the structure of the tunnel door compared to being directly installed on a vacuum pipe; ...

Embodiment 2

[0043] The difference from Embodiment 1 is that the sliding structure of this embodiment is a roller mechanism. The roller mechanism includes a plurality of rollers, and the rollers are fixed on the fixed channel at intervals through roller seats.

[0044] Other structures are with embodiment 1.

Embodiment 3

[0046] The difference from Example 1 is that a plurality of first grooves are arranged at intervals on the opposite side of the fixed channel and the air baffle, and the first grooves of the fixed channel and the first grooves of the air baffle are alternately arranged, and the balls set in the first groove.

[0047] Other structures are with embodiment 1.

Abstract

A vacuum train gas insulation type access device comprises a vacuum pipeline and a train which is positioned in the vacuum pipeline; a fixed passage is connected to the vacuum pipeline; a tunnel is arranged on the fixed passage; one end of the fixed passage is connected with a telescopic gas insulation cover; and a sliding structure beneficial for the gas insulation cover to move is arranged between the gas insulation cover and the fixed passage. The invention further comprises another vacuum train gas insulation type access device. On the basis of simplifying the structure, the vacuum train gas insulation type access device also has the advantages that time and labor are saved, labor cost is saved and the working efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of vacuum trains, in particular to a vacuum train air barrier entry and exit device. Background technique [0002] Since the vacuum train runs at a high speed in the vacuum pipeline, both the train and the vacuum pipeline must maintain airtightness during operation to prevent air leakage. After arriving at the station, passengers need to get on and off the station, or when transporting goods, the goods also need to be input and output, which requires opening the hatch door on the train and the tunnel door on the vacuum pipeline to realize getting on and off the train. Opening the door will cause gas leakage. Therefore, it is necessary to balance the pressure of the pipeline and the train to ensure the vacuum state of the vacuum pipeline, and to move passengers or goods in and out at the same time. This is a technical problem that needs to be solved urgently. [0003] CN100484812C discloses a connection corr...
