The invention discloses a connection gallery bridge system suitable for vacuum pipeline transportation, and belongs to the technical field of rail transportation. The system comprises a fixed gallerybody, and the fixed gallery body and a telescopic butt joint body provided with a positioning and attaching mechanism form a horizontal moving pair; a rear end of the telescopic butt joint body is connected with the inner end of the fixed gallery body through a compensation sealing link; and one end of the telescopic butt joint body is provided with an anastomosis end surface, the anastomosis endsurface is provided with a circumferential caulking groove, a sealing ring is fixedly embedded in the circumferential caulking groove, and protruding edges higher than the anastomosis end surface arearranged on the two sides of the section of the sealing ring and form a sealing pair with the surface of a vehicle body. After the system is adopted, when the anastomosis end surface of the telescopicbutt joint body is attached to the surface of the vehicle body, the two can be tightly attached through a positioning and attaching mechanism so that the sealing ring generates elastic deformation, multiple reliable seals are formed, meanwhile, sealing between the telescopic butt joint body and the fixed gallery body is guaranteed through a compensation sealing link, and a purpose of effectivelyisolating a vacuum channel from a connection channel and an inner portion of a train is achieved.
本发明公开了一种适用于真空管道交通的接驳廊桥系统,属于轨道交通技术领域。该系统包括固定廊体,固定廊体与装有定位贴紧机构的伸缩对接体构成水平移动副;伸缩对接体的后端通过补偿密封环节连接固定廊体的内端;伸缩对接体的一端具有吻合端面,吻合端面具有周圈嵌槽,周圈嵌槽内嵌固密封圈,密封圈的截面两侧具有高出吻合端面的凸边,与车体表面构成密封副。采用本发明后,当伸缩对接体的吻合端面贴靠车体表面时,定位贴紧机构可以使两者之间贴紧,从而使密封圈产生弹性变形,形成可靠的多道密封,同时借助补偿密封环节保证伸缩对接体与固定廊体之间的密封,达到将真空通道与接驳通道及列车内有效隔离的目的。
