Connecting channel

Abstract

The invention provides a connecting channel. The connecting channel comprises a telescopic bridge body channel and an awning device, wherein the awning device comprises a door-shaped frame and a docking frame; the docking frame comprises a hard frame and a flexible frame; retraction mechanisms and an energy storage device are connected between the door-shaped frame and the hard frame; the hard frame and the flexible frame are respectively hinged to a non-telescopic floor; the flexible frame is hinged to the front end of the floor, and two side ends of the front end of the floor and two side branches of the flexible frame are respectively provided with distance measuring instruments; a plurality of actuators are connected between the hard frame and the flexible frame; and hinged joints of the actuators on each side branch of the flexible frame and mounting points of the distance measuring instruments are vertically crosswise arranged. By a boarding bridge provided by the invention, the tightness and the security are improved.

Description

technical field [0001] The present invention relates to a connection channel, in particular to a boarding bridge including a canopy device, and in particular to a boarding bridge including a docking frame that can adaptively have a shape conforming to the curvature of the plane surface before docking with the plane 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. [0003] Patent document CN100355628C discloses a sealing device for aircraft passenger ladders or aircraft boarding bridges, comprising a bellows tensioned above a co...

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
