End element for abutting joint

Abstract

The invention relates to an abutting-joint frame for an awning device. The abutting-joint frame comprises a hard frame, a flexible frame and a telescopic floor section, wherein the telescopic floor section realizes extension and shrinkage in a floor layer by a first actuator, the hard frame is articulated to a floor, the flexible frame is fixedly connected to the front end of the telescopic part, range finders are respectively arranged on branches at two sides of the hard frame, and a plurality of range finders are arranged on the branches in a dispersing manner; and a plurality of second actuators are connected between the hard frame and the flexible frame; and the lateral branches of the hard frame are wider than those of the flexible frame, the find rangers on the hard frame are arranged on the excessive width, and the hard frame of the abutting-joint frame is connected to a portal frame of the owning device through a contraction and release mechanism and an energy accumulation device. Due to utilization of the abutting-joint frame, the sealing property and the safety of a boarding bridge are improved.

Description

technical field [0001] The present invention relates to an end element for docking, in particular to a docking frame for an awning device, in particular to a docking frame that can adaptively have a shape conforming to the curvature of the aircraft surface before docking with the aircraft frame. 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, wherein the ...

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
