Description
Technical field
The present invention relates to vacuum train technical field, especially a kind of vacuum train trapping access apparatus.
Background technology
Since vacuum train is run in vacuum pipe high speed, train and vacuum pipe all put into operation process
In will keep air-tightness, prevent leakage air.And after reaching website, passenger needs station up and down, or when transport cargo, cargo
Input and output are also required to, this just needs to open the tunnel door on the hatch door and vacuum pipe on train, and realization is got on or off the bus.And it opens the door just
Gas can be caused to leak, thus should equalizing main and train pressure, ensure the vacuum state of vacuum pipe, again simultaneously will
The technical issues of passenger or cargo move in and out, are urgent need to resolve.
CN100484812C discloses a kind of assembling corridor for vacuum pipe traffic, and place is equipped with one end and is embedded in AT STATION
Tubular in vacuum pipe fixes corridor, and the fixed corridor other end connects with station platform, and fixed corridor is connect with vacuum pipe
Place's sealing；The front inner wall sealing in fixed corridor is sheathed with telescopic corridor；One end of telescoping mechanism is connected with telescopic corridor, another
End is connected with fixed corridor, and the front end of telescopic corridor is along with the shape adaptation around the car door of compartment and equipped with sealing strip；
Fixed corridor middle and back is equipped with hermatic door.Although the technology simplifies structure, but still have the following defects：（1）The technology is
Telescopic corridor movement, frictional force are driven using the mechanical structure of the complexity such as hydraulic telescopic machanism or rack-and-pinion telescoping mechanism
Greatly, if it is hand push, labor intensity is greatly improved, if using electronic or other modes, also will increase energy consumption；（2）The technology
Be by platform personnel control telescopic corridor move, on the one hand need monitor just know train whether on-board and off-board, reduction efficiency；Separately
On the one hand, it is also necessary to which configuration personnel go to open, waste of manpower, improve cost.
Invention content
A kind of simple in structure, time saving and energy saving, efficiency is provided the purpose of the present invention is overcoming the above-mentioned insufficient of the prior art
High vacuum train trapping access apparatus.
The technical scheme is that：
A kind of vacuum train vehicle trapping access apparatus of the present invention, including vacuum pipe and the train in vacuum pipe, vacuum
Fixed channel is connected on pipeline, fixed channel is equipped with tunnel door；The one end in fixed channel connects telescopic gas insulating cover；Trapping
It is equipped with the slide construction for being conducive to gas insulating cover movement between cover and fixed channel.
The present invention has the following advantages：By the way that slide construction is arranged, for existing telescoping mechanism, have following excellent
Point：（1）Structure is greatly simplified, it is not necessary that complicated mechanical structure is arranged；（2）Frictional force can be reduced, it, can if Manual push-pull
It is time saving and energy saving；If electric push-and-pull, energy consumption can be reduced.
Preferably, slide construction is guiding mechanism, and guiding mechanism is preferably rolling mechanism or sliding track mechanism；Rolling mechanism is logical
It crosses rolling or rotation drives gas insulating cover movement, to reduce friction coefficient.
It is highly preferred that the slide construction is idler wheel, ball or sliding track mechanism.Slide construction can be fixed on fixed channel
