Shed device for boarding bridge

Abstract

The invention provides an awning device for a boarding bridge. The awning device comprises a door-shaped framework, a docking framework and a telescopic floor, wherein the telescopic floor comprises a telescopic part located at a front end, the telescopic part stretches and retracts by virtue of a first actuator, the docking framework comprises a hard framework and a flexible framework, a retraction jack and an energy storage device are connected between the door-shaped framework and the hard framework, the hard framework is articulated with the floor, the flexible framework is fixedly connected with the front end of the telescopic part, and a plurality of range finders are respectively arranged on two side branches of the hard framework in a dispersion manner; a plurality of second actuators are connected between the hard framework and the flexible framework; and the lateral branches of the hard framework are wider than that of the flexible framework, and the range finders on the hard framework are arranged on the positions within the width ranges beyond the width ranges of the lateral branches of the flexible framework. By utilization of the awning device disclosed by the invention, the tightness and safety are improved.

Description

technical field [0001] The present invention relates to a frame assembly, in particular to a canopy device for a boarding bridge, in particular to a canopy comprising a docking frame that can adaptively have a shape conforming to the curvature of the surface of the plane before it is docked with the plane canopy 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 conne...

AI Technical Summary

Problems solved by technology

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

[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
