Sealing element

Abstract

The invention provides a sealing element. A butt-joint framework for an awning device comprises a hard framework and a flexible framework, wherein the hard framework and the flexible framework are respectively hinged to a floor; the flexible framework is hinged to the front end of the floor; distance measuring instruments are further respectively arranged two side end parts of the front end of a floor layer and branches at the two sides of the flexible framework; a plurality of actuators are connected between the hard framework and the flexible framework; an actuator hinging point and a distance measuring instrument mounting point of the branch of each side of the flexible framework are staggered in a vertical direction; and the hard framework of the butt-joint framework is connected to a door-shaped framework of the awning device through a retraction device and an energy storing device. With the adoption of the butt-joint framework, the sealing performance and the safety of an aerobridge are improved.

Description

technical field [0001] The invention relates to a closing element, in particular to a docking frame for an awning device, 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. 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 canopy device at its end, which bridges the space between the boarding bridge and the aircraft, so as to protect the boarding personnel from the influence of bad 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, wherein the bellows has a flexible ...

Problems solved by technology

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

[0006] Therefore, the canopy device in the prior art generally has the following defects: due to the single point of application of 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 awning device touches the fuselage shell, it is easy to cause damage to the fuselage shell by itself. Faults or system errors cause overload, which seriously damages the fuselage shell; there is a lack of real-time detection and alarm devices during the passenger boarding process, posing safety hazards
