Butting method for sealing device

Abstract

The invention discloses a butting method for a sealing device and provides an expanding method of an awning method. The expansion method comprises the following steps: laser distance meters are started to measure the distance from a flexible frame to an airframe of an airplane, when a boarding bridge moves towards the airplane in the vertical direction and approaches to the airplane to be butted with in a certain distance, the boarding bridge is temporally stopped from being close to the airplane; the flexible frame is controlled to be deformed by utilizing the distance measured by the multiple laser distance meters and actuators, and the deformed flexible frame is enabled to have the same curvature of the airplane skin to be butted; the boarding bridge is controlled to continuously move forwards, and when the laser distance meter at the front end of a floor measures that the distance reaches the preset value, the boarding bridge is braked; and a controller controls a winding mechanism to release an energy storage device, so that a butting frame is enabled to be tightly pressed on the airplane skin in a fitting manner through the energy storage device. With the adoption of the expanding method for the awning device, the air tightness and safety are improved.

Description

technical field [0001] The invention relates to a docking method of a sealing device, in particular to a method for deploying an awning device, in particular to an awning comprising a docking frame which can adaptively have a shape conforming to the curvature of the surface of the aircraft before docking with the aircraft The deployment method of the device. 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 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
