Transport plane rear cargo-bridge cabin-door structure capable of reducing cargo-bridge landing angle

Abstract

The invention provides a transport plane rear cargo-bridge cabin-door structure capable of reducing a cargo-bridge landing angle. The rear cargo-bridge cabin-door structure comprises a plane body cargo bridge, an auxiliary cargo bridge and a connecting device, wherein the end part of the auxiliary cargo bridge is connected with that of the plane body cargo bridge through the connecting device; the connecting device can drive the auxiliary cargo bridge to rotate; the connecting device comprises a plane body cargo-bridge connecting frame, an auxiliary cargo-bridge connecting frame, a connecting device bracket, a rotary mounting shaft, and a locking device. According to the invention, the cargo bridge length can be prolonged by folding or rotating the cargo bridge to reduce the cargo bridge landing angle. Meanwhile, a plane cargo space freight transport system can be additionally mounted on the rear cargo-bridge cabin-door structure and is convenient to open or pack up. When the plane cargo space freight transport system is opened, all cargo bridges are on the same plane, can bear a certain weight, and facilitates cargo loading and transport; when the plane cargo space freight transport system is integrated with a cabin door after being packed up, so that the plane cargo space freight transport system does not affect the normal aerodynamic configuration of the transport plane; when transport tasks (airborne landing, and steep lifting and loading) which do not need to increase cargo bridge length are executed, the plane body cargo bridge can also be used normally.

Description

technical field [0001] The invention relates to the technical field of cargo loading systems for aircraft such as airplanes, in particular to a rear cargo bridge hatch structure of a transport aircraft that can reduce the landing angle of the cargo bridge. Background technique [0002] The cargo door is a moving functional part on the transport aircraft. Its function, service life, safety, maintainability and reliability are directly related to the attendance rate of the aircraft. The cargo door on the side of the cargo compartment under the fuselage is generally opened inwards and upwards, and the cargo door on the side of the cargo compartment on the upper fuselage is opened outwards and upwards; the tail door of the fuselage is generally composed of multiple pieces, and the lower tail cargo compartment The door generally doubles as a cargo bridge and opens downward. [0003] When the cargo bridge door at the tail of the transport aircraft is opened and lowered to make a ...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the problems in the prior art that the landing angle of the cargo bridge hatch of the transport aircraft is too large after it is completely lowered, and the installation and use of the simple cargo bridge are inconvenient, the present invention proposes a rear cargo bridge hatch of a transport aircraft that can reduce the landing angle of the cargo bridge structure
