Aircraft repair dock used for repairing aircraft empennages

Abstract

The invention discloses an aircraft repair dock used for repairing aircraft empennages. The aircraft repair dock comprises a flat tail dock body and a vertical tail dock body. A flat tail dock body framework is connected with the ground through lifting regulation supports. A vertical tail dock body framework is lifted on track beams through lifting mechanisms and can move vertically along the lifting mechanisms, and the lifting mechanisms can move horizontally along the track beams. A bottom layer working platform of the vertical tail dock body framework adopts an adjustable-dip-angle workingplatform. Anti-falling mechanisms are mounted between the vertical tail dock body framework and the lifting mechanisms. Through the lifting regulation supports, non-axial stress caused by distortion deformation of the flat tail dock body framework can be effectively counteracted; after the vertical tail dock body is adjusted to a repair position, the adjustable-dip-angle working platform can be actively matched with the dip angle of the upper surface of an aircraft tail by adjusting the dip angle of the working platform, the repair time is saved, and the repair efficiency is improved; and theanti-falling mechanisms can be locked automatically, once the vertical tail dock body falls, the process of the vertical tail dock body from falling to locking is a reduced speed friction process, andinstantaneous impact is avoided.

Description

technical field [0001] The invention belongs to the technical field of aircraft repair docks, in particular to an aircraft repair dock for repairing aircraft empennages. Background technique [0002] The aircraft repair dock is a platform used for aircraft maintenance. When the aircraft tail needs to be repaired, the aircraft repair dock consisting of a flat tail dock and a vertical tail dock is required. [0003] For the flat tail dock, the existing flat tail dock generally adopts a fixed structure, and can be adjusted up and down. The synchronous operation of the lifting adjustment bracket can realize the rise or fall of the flat tail dock as a whole. However, since the main frame of the flat tail dock is rigidly connected, when the entire flat tail dock is driven up or down by the lifting adjustment bracket, if the synchronous operation accuracy of the four lifting adjustment brackets is low, it will cause the main frame of the flat tail dock to a certain degree. twisti...

Problems solved by technology

But, for the passenger plane that the upper surface of the tail cone of the aircraft is inclined, the working platform of the fixed horizontal structure will be difficult to adapt to the upper surface of the tail cone of the aircraft, and when the upper surface of the tail cone of the aircraft is maintained, only The working platform can reach the designated maintenance position by frequently adjusting the overall position of the vertical tail dock. Once the maintenance position is changed, the overall position of the vertical tail dock needs to be adjusted again, resulting in a lot of time wasted on the position adjustment of the vertical tail dock , thus seriously affecting the efficiency of aircraft maintenance

[0005] In addition, the existing vertical tail docks generally adopt a gantry-like structure, and the vertical tail dock is installed in a suspended manner as a whole. In the process of adjusting the overall position of the vertical tail dock, in order to avoid falling accidents of Tail dock equipped with anti-drop mechanism

However, the traditional anti-fall mechanism is generally a steel wire riveting structure. Every time the position of the vertical tail dock is adjusted, the steel wire rope needs to be riveted again, which makes the riveting operation process more complicated. In order to ensure that the anti-fall mechanism has certain activities The steel wire rope after riveting needs to maintain a certain slack state. Once the vertical tail dock falls, the loose steel wire rope will be quickly tightened when the vertical tail dock falls, and the impact force when the vertical tail dock falls will instantly act on the vertical tail. On the hoisting mechanism of the vertical tail dock, if the instantaneous impact force exceeds the bearing limit of the hoisting mechanism of the vertical tail dock, serious safety accidents are likely to occur
