Method for manipulating connecting channel

Abstract

The invention provides a method for manipulating a boarding bridge. The method comprises the following steps of: starting laser range finders to measure distances from a flexible framework to an airplane body, and when the boarding bridge stretches and advances towards the airplane vertically and approaches the airplane to be docked by a certain distance, temporarily stopping the motion of the boarding bridge approaching the airplane; controlling the deformation of the flexible framework by using the distances measured by the plurality of laser range finders and by actuators so as to make the deformed flexible framework achieve the same surface curvature as that of a casing of the airplane body to be docked; continuously controlling the boarding bridge to advance, and braking the boarding bridge when the distance measured by the laser range finder at the front end of a floor reaches a preset value; and controlling a winding mechanism to release an energy storage device by a controller so as to tightly press a docking framework to fit the casing of the airplane body. By utilization of the method for manipulating the boarding bridge, disclosed by the invention, the tightness and safety are improved.

Description

technical field [0001] The present invention relates to a connecting channel manipulation method, in particular to a boarding bridge manipulation method, in particular to a boarding bridge including a docking frame which can adaptively have a shape conforming to the curvature of the plane surface before docking with the plane manipulation method. 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 bell...

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
