Frame and airplane jointing method

Abstract

The invention provides a frame and airplane jointing method. The frame and airplane jointing method includes steps of starting laser range finders to measure the distance between a flexible frame to an airplane body, and temporarily stopping motion of a boarding bridge getting close to the airplane when the boarding bridge perpendicularly advances towards the airplane and gets close to the airplane to be jointed by a certain distance; controlling the flexible frame to deform by an actuator according to the distance measured by the laser range finder so as to enable the deformed flexible frame to be provided with surface curvature same with a housing of the airplane body to be jointed; keeping controlling the boarding bridge to advance and braking the boarding bridge when the distance measured by the laser range finders between the flexible frame and the airplane body reaches the preset value; controlling a first actuator to enable telescopic plates to extend to be fitted to the housing of the airplane body according to range finders on the telescopic plates; controlling a winding mechanism to release an energy storage device by a controller so that the jointed frame can be tightly pressed to the housing of the airplane body. By the aid of an unfolding method of a folding device, sealing property and safety are improved.

Description

Technical field [0001] The present invention relates to a method for joining a frame and an aircraft, in particular to a method for deploying a bellows device, and in particular to a folding frame including a docking frame that can adaptively have a shape that matches the curvature of the plane surface before docking with the aircraft. How to unfold the shed 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 bellows device at its end, which bridges the space between the boarding bridge and the aircraft, so as to protect the boarding personnel from the adverse weather conditions. [0003] Patent document CN100355628C discloses an aircraft passenger ladder or aircraft boarding bridge sealing device, including a bellows immediately abo...

Problems solved by technology

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

[0006] Therefore, the bellows device deployment method 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 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 bellows 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
