Method for curved docking with airplanes

Abstract

The invention provides a method for curved docking with airplanes. The method includes the steps: turning on a laser distance meter to meter the distance between a flexible framework and an airframe, and when an aerobridge advances vertically towards an airplane and approaches to the airplane to be docked by a certain distance, temporarily discontinuing the movement of the aerobridge approaching to the airplane; controlling the flexible framework to deform by the aid of the metered distances of multiple laser distance meters and an actuator, and enabling the deformed flexible framework and a shell of the airframe to be docked to have the same surface curvature; continuing to control the aerobridge to advance, and when the metered distance of the laser distance meter of the flexible frame reaches a preset value, braking the aerobridge; according to a distance meter on an extensible floor section, controlling a first actuator to enable the extensible floor section to extend to be laminated with the shell of the airframe; and controlling a winding mechanism to release an energy storage device by a controller so as to closely laminate the docking framework to the shell of the airframe. By the aid of the canopy device unfolding method, sealability and safety are improved.

Description

technical field [0001] The present invention relates to a method for bending and docking with an aircraft, in particular to a method for deploying an awning device, in particular to an awning including a docking frame that can adaptively have a shape conforming to the curvature of the surface of the aircraft before docking with the aircraft How to deploy the canopy. 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 bridge...

AI Technical Summary

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
