Deformable assembly

Abstract

The invention discloses a deformable assembly which is used for an abutting frame of an awning device. The deformable assembly comprises a hard frame and a flexible frame; the hard frame can be hinged with a floor which cannot be extended and retracted; the flexible frame is fixedly connected to the front end of the floor; a plurality of distance meters are arranged on branches on two sides of the hard frame dispersedly; a plurality of actuators are connected between the hard frame and the flexible frame and are distributed on the branches of the hard frame dispersedly; the branches on the side of the hard frame are wider than the branches on the side of the flexible frame; and the range meters on the hard frame are arranged on the parts of the excessive widths, and the hard frame of the abutting frame is connected to a portal frame of the awning device through a retraction and releasing mechanism and an energy storage device. By using the abutting frame, the sealing performance and the safety of a boarding bridge are improved.

Description

technical field [0001] The invention relates to a deformable assembly, in particular to a docking frame for an awning device, 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. 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 f...

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
