Butting method for bridge type channel

Abstract

The invention relates to a butting method for a bridge type channel, and provides a boarding bridge manipulating method, which comprises the following steps that laser distance measuring instruments are started to measure the distance from a flexible framework to an airplane fuselage, and a boarding bridge perpendicularly extends and marches towards an airplane and is temporarily stopped from moving close to the airplane when being away from the airplane needing to be butted by a certain distance; the deformation of the flexible framework is controlled by utilizing the distance measured by the plurality of laser distance measuring instruments and brakes so as to enable the deformed flexible framework to have the same surface curvature with a fuselage shell needing to be butted; the boarding bridge is continuously controlled to march and is braked when the distance measured by the laser distance measuring instrument at the front end of a floor reaches a preset value; and a winding mechanism is controlled by a controller to release an energy storage device so as to enable the energy storage device to tightly press the butted framework on the fuselage shell. By utilizing the boarding bridge manipulating method provided by the invention, the sealability and the safety are improved.

Description

technical field [0001] The invention relates to a docking method of a bridge-shaped channel, in particular to a method for manipulating a boarding bridge including a docking frame that can adaptively have a shape conforming to the curvature of the aircraft surface 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 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
