Intermediate equipment for transporting passengers

Abstract

The invention provides intermediate equipment for transporting passengers, and particularly relates to a boarding bridge. The intermediate equipment comprises an extension-type bridge body passageway and an awning device. The awning device comprises a door-shaped frame, butt joint frames and an extension-type floor. The extension-type floor comprises an extension-type part located at the front end capable of stretching out and drawing back by means of a first actuator. The butt joint frames comprise a hard frame and a flexible frame, the flexible frame is higher than the hard frame, a releasing-placing mechanism and an energy storage device are connected between the door-shaped frame and the hard frame, and the hard frame is hinged to the outer side of the floor. A plurality of second actuators are connected between the hard frame and the flexible frame, and one of the second actuators is fixedly connected to the hard frame with the help of a support in a non-pivoted mode. Distance measuring instruments are further arranged on branches on the two sides of the flexible frame and the front end of the extension-type part respectively. By the adoption of the boarding bridge, leakproofness and safety are improved.

Description

technical field [0001] The present invention relates to an intermediate device for transporting passengers, in particular to a boarding bridge including a canopy device, in particular to a docking bridge which can adaptively have a shape conforming to the curvature of the surface of the aircraft before docking with the aircraft Frame boarding 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 ...

AI Technical Summary

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
