Closed docking framework

Abstract

The invention discloses a docking framework for an awning device. The docking framework comprises a hard framework and a flexible framework, wherein the hard framework is articulated with a non-telescopic floor, the flexible framework is fixedly connected with the front end of the floor, a plurality of range finders are respectively arranged on two side parts at the front end of a floor layer and two side branches of the hard framework, and a plurality of actuators are connected between the hard framework and the flexible framework; and the lateral branches of the hard framework are wider than that of the flexible framework, the range finders on the hard framework are arranged on the positions within the width ranges beyond the width ranges of the lateral branches of the flexible framework, and the hard framework of the docking frame is connected with a door-shaped framework of the awning device through a retraction jack and an energy storage device. By utilization of the docking framework disclosed by the invention, the tightness and safety of a boarding bridge are improved.

Description

technical field [0001] The invention relates to an airtight docking structure, 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...

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
