Butting device comprising deformable frame

Abstract

The invention provides a butting device comprising a deformable frame, which comprises a portal frame, a butting frame and a telescopic floor, wherein the telescopic floor comprises a telescopic part located at the front end; the telescopic part extends and contracts by using a first actuator; the butting frame comprises a hard frame and a flexible frame; the flexible frame is higher than the hard frame; a retraction jack and an energy storage device are connected between the portal frame and the hard frame; the hard frame is articulated with the outer side of the floor; a plurality of second actuators are connected between the hard frame and the flexible frame; one of the second actuators is fixedly connected with the hard frame in a non-pivoted manner by a support; and range finders are arranged at branches on the two sides of the flexible frame and the front end of the telescopic part respectively. The sealability and safety of an awning device adopting the butting device are improved.

Description

technical field [0001] The present invention relates to a docking device comprising a deformable frame, in particular to an awning device for a boarding bridge, and in particular to a canopy device which can adaptively have a shape conforming to the curvature of the aircraft surface before docking with the aircraft The butt frame of the 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...

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
