Sealing device controlling method

Abstract

The invention provides an awning device unfolding method which comprises the following steps: enabling laser range finders to measure the distance from a flexible frame to an aircraft body, and before the aerobridge vertically advances toward the aircraft and further approaches to the aircraft for docking by a certain distance, temporarily stopping the movement of the aerobridge approaching to the aircraft; measuring the distance by using the plurality of laser range finders and controlling the deformation of the flexible frame by the actuators, so that the deformed flexible frame has the same surface curvature as a housing of the aircraft body for docking; continuing controlling the aerobridge to advance, and when the distance measured by the laser range finders at the front end of the floor reaches a predetermined value, braking the aerobridge; and controlling a winding mechanism to release an energy storage device by a controller, so that the energy storage device tightly presses the docking frame to the craft body housing. By adopting the awning device unfolding method, the sealability and the safety are improved.

Description

Technical field [0001] The invention relates to a control method of a sealing device, in particular to a method for unfolding an awning device, and in particular to an awning including a docking frame that can adaptively have a shape that matches the curvature of the plane surface before docking with the plane How to deploy the device. Background technique [0002] Aircraft boarding bridges are a type of airport equipment commonly used by modern passenger aircraft. They are used as the entrance for boarding and allow passengers to enter the interior of the aircraft from the terminal. This kind 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 adverse weather conditions. [0003] Patent document CN100355628C discloses an aircraft passenger ladder or aircraft boarding bridge sealing device, including a bellows immediately above a connecting floor, wherein the b...

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
