Transporting device

Abstract

The invention relates to a transporting device and provides a boarding bridge comprising an awning device. The boarding bridge comprises a retractable bridge body channel and the awning device, wherein the awning device comprises an n-shaped frame, a butting frame and a retractable floor, wherein the retractable floor comprises a retractable part which is positioned at the front end of the retractable floor; the retractable part extends and retracts by using a first actuator; the butting frame comprises a hard frame and a flexible frame; a retraction mechanism and an energy storage device are connected between the n-shaped frame and the hard frame; the hard frame is hinged to the floor; the flexible frame is fixedly connected with the front end of the retractable part; distance measuring instruments are arranged on two side branches of the hard frame; a plurality of distance measuring instruments are dispersedly arranged on the branches; a plurality of second actuators are connected between the hard frame and the flexible frame; and a lateral branch of the hard frame is wider than a lateral branch of the flexible frame, and the distance measuring instruments on the hard frame are arranged on the extra part of the lateral branch. By using the boarding bridge, the tightness and safety are improved.

Description

technical field [0001] The present invention relates to a transportation device, in particular to a boarding bridge including a canopy device, and in particular to a boarding bridge including a docking frame that can adaptively have a shape conforming to the curvature of the plane surface before docking with the plane. aircraft 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 bellows tension...

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
