Awning device unfolding method

Abstract

The invention provides an awning device unfolding method. The awning device unfolding method comprises the following steps: opening a laser rangefinder to measure the distance from a flexible frame to an aircraft body; enabling a boarding bridge to vertically advance to an aircraft; temporarily stopping the motion of the boarding bridge approaching the aircraft when the boarding bridge is close to the aircraft to be abutted against the boarding bridge; controlling the flexible frame to deform through the adoption of distances measured by a plurality of laser rangefinders and through the adoption of an actuator, so that the deformed flexible frame and an aircraft body housing to be abutted have same surface curvatures; continuing to control the boarding bridge to advance; braking the boarding bridge when the measured distance of the laser rangefinder at the front end of a floor reaches a preset value; and controlling a winding mechanism to release an energy storage device through a controller, so that the abutted frame is closely pressed on the aircraft body housing through the energy storage device. Through the adoption of the awning device unfolding method provided by the invention, the sealing property and safety are improved.

Description

technical field [0001] The invention relates to a method for deploying an awning device, in particular to a method for deploying an awning device including a docking frame which can adaptively have a shape conforming to the curvature of the surface of the aircraft 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...

Problems solved by technology

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

[0006] Therefore, the method for deploying the canopy device in the prior art generally has the following defects: due to the single force point 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 performance are relatively poor; Fitting the flexible frame tightly to the fuselage shell usually requires a relatively large force, 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 Due to its own failure or system error, the overload caused serious damage to the fuselage shell; the lack of real-time detection and alarm devices during the passenger boarding process has potential safety hazards
