Erecting method of boarding bridge

Abstract

The invention discloses a control method of a boarding bridge, which comprises the following steps of: starting laser range finders for measuring distances between a flexible frame and an airplane body, when the boarding bridge extends towards the airplane vertically to advance and approaches the airplane to be docked by a certain distance, temporarily stopping the movement of the boarding bridge close to the airplane body; controlling the deformation of the flexible frame by using the distances measured by the plurality of laser range finders and an actuator to ensure that the deformed flexible frame and a housing of the airplane to be docked have same surface curvature; continuously controlling the boarding bridge to advance, when the distance measured by the laser range finder on the front end of a floor reaches a preset value, braking the boarding bridge; and controlling a headway to release an energy storage device by a controller to ensure that a butting frame is tightly pressed and compacted on the housing of the airplane body. By using the control method of the boarding bridge, provided by the invention, the sealing property and the safety are improved.

Description

technical field [0001] The present invention relates to a method for erecting a boarding bridge, in particular to a method for operating a boarding bridge, and in particular to a boarding frame including a docking frame that can adaptively have a shape conforming to the curvature of the surface of the plane before docking with the plane How to operate the bridge. 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.

AI Technical Summary

Problems solved by technology

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

[0006] Therefore, the boarding bridges in the prior art generally have 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 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
