Divided type movable isolating door setting for vacuum pipeline transportation

Abstract

The invention provides a divided type sideward / horizontally movable isolating door setting for a vacuum pipeline (or vacuum tunnel) transportation, which is particularly suitable for isolating a vacuum environment of the vacuum pipeline transportation in which a T-shaped magnetic levitation track is used. The divided type movable isolating door setting comprises a door chamber, a door chamber body wall, two symmetrically-arranged isolating doors, a T-shaped track, a movable trench and the like, wherein the door chamber is formed by the surrounding of the door chamber body wall and is positioned on the two sides of a vacuum pipeline; the isolating doors are moved in a rolling or sliding mode; and horizontal and vertical jacking locking devices are arranged inside the door chamber and at the proper positions on the isolating doors, and are used for jacking and sealing the sealing parts of the isolating doors. The isolating door setting meets the requirement of isolating the vacuum environment of a vacuum pipeline route and can prevent the magnetic levitation track from being blocked simultaneously.

Description

technical field [0001] The invention relates to a vacuum environment side-opening mobile isolation door device for vacuum pipeline (or vacuum tunnel) traffic, and belongs to the technical field of vacuum environment boundary structure for vacuum pipeline traffic. Background technique [0002] The vacuum chamber of the vacuum pipeline high-speed maglev transportation will be the largest vacuum environment artificially formed, and it will extend to thousands of kilometers or even tens of thousands of kilometers. For such a huge vacuum system, in order to meet the needs of operation, maintenance and vacuum maintenance, it is necessary Position setting isolation device - isolation door. The vacuum chambers used for simulation tests in the existing spacecraft and aerospace fields and the vacuum chambers in other industrial fields all have hinged hinged door covers.

Patent application "A Hermetic Door Used in Vacuum Pipeline System" (Application No. 200710049346.0, Publication No. CN101078352, Publication Date 2007.11.28) discloses a vacuum-environment airtight door pulled by a wire rope. The advantage is that the airtight door has no Structural components protruding beyond the boundary of the vacuum pipe wall, the disadvantage is that it occupies the inner space of the pipe and reduces the clearance for vehicles to drive in the vacuum pipe

For the normally conductive electromagnetic levitation vehicle, the blockage caused by the horizontal channel to the maglev track will also cause the suspension to be terminated, and the support wheels must be relied on to pass through the isolation door

The patent application "A Vertically Moving Isolation Door for Vacuum Pipeline Traffic" (application number 200910219090.2, application date 2009.11. The vacuum pipeline / tunnel traffic system of the "T" track of the embracing maglev system (such as the maglev of Shanghai Pudong Airport Line)
