Sealing device for docking

Abstract

The invention provides an awning device for a boarding bridge. The awning device comprises a door-shaped framework, a docking framework and telescopic floor, wherein the telescopic floor comprises a telescopic part at a front end, the telescopic part stretches and contacts by using a first actuator, the docking framework comprises a hard framework and a flexible framework, a retraction jack and energy storage equipment are connected between the door-shaped framework and the hard framework, and diastimeters are respectively arranged on two lateral end parts at the front end of the telescopic part of the floor and two lateral branches of the flexible framework; and a plurality of second actuators are connected between the hard framework and the flexible framework, and an actuator hinge point and a diastimeter mounting point, on each lateral branch of the flexible framework, are obliged to be staggered in a vertical direction. By utilization of the awning device disclosed by the invention, the sealability and safety are improved.

Description

technical field [0001] The present invention relates to a docking sealing device, in particular to an awning device for a boarding bridge, especially to a docking frame which can adaptively have a shape conforming to the curvature of the aircraft surface before docking with the aircraft Awning 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. [0003] Patent document CN100355628C discloses a sealing device for aircraft passenger ladders or aircraft boarding bridges, comprising a bellows tensioned above a connection floor, wherei...

AI Technical Summary

Problems solved by technology

[0006] Therefore, the canopy device in the prior art generally has the following defects: due to the single point of application 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
