Air blocking space structure

Abstract

The invention relates to an air blocking space structure and provides a gangway device for a boarding bridge. The gangway device comprises a portal framework and a butt joint framework, wherein the butt joint framework comprises a hard framework and a flexible framework, a contraction and release mechanism and an energy accumulator are connected between the portal framework and the hard framework, the hard framework is hinged with a non-telescopic floor, the flexible framework is fixedly connected with the front end of the floor, a plurality of distance measuring instruments are respectively arranged on branches arranged at two sides of the hard framework and are in scattered arrangement on the branches, a plurality of actuators are connected between the hard framework and the flexible framework and are in scattered arrangement on the hard framework, lateral branches of the hard framework need to be wider than the lateral branches of the flexible framework, and the distance measuring instruments arranged on the hard framework are arranged on the excessive widths. When the gangway device is utilized, the sealing performance and the safety are improved.

Description

technical field [0001] The present invention relates to a wind-shielding space structure, in particular to a bellows device for boarding bridges, and in particular to a docking frame which can adaptively have a shape conforming to the curvature of the aircraft surface before docking with the aircraft folding shed device. Background technique [0002] Airplane boarding bridge is a piece of airport equipment commonly used by modern passenger aircraft. They are used as the entrance for boarding, allowing passengers to enter the interior of the passenger aircraft from the terminal building. This type of boarding bridge usually has a bellows device at its end, which bridges the space between the boarding bridge and the aircraft, so as to protect boarding personnel from adverse weather conditions. [0003] Patent document CN100355628C discloses a sealing device for aircraft passenger ladders or aircraft boarding bridges, comprising a bellows tensioned above a connection floor, wh...

The above two documents are still relatively single for the use of laser rangefinders

[0006] Therefore, the bellows device in the prior art generally has the following defects: due to the single point of force applied by the energy storage device or the actuator, the flexible frame is difficult to adapt to various aircraft surface curvatures, and the flexibility and sealing are poor; The frame fits closely to the fuselage shell, and the force usually exerted is relatively large, which is easy to damage the fuselage shell. In addition, since the energy storage device or actuator usually starts to work after the bellows device touches the fuselage shell, it is easy to cause damage to the fuselage shell due to its own Faults or system errors cause overload, which seriously damages the fuselage shell; there is a lack of real-time detection and alarm devices during passenger boarding, posing safety hazards
