Ultra-long aircraft floor mounting device and mounting method

Abstract

The invention discloses an ultra-long aircraft floor mounting device and method. The device comprises a plurality of sets of rubber air bag assemblies, an electric winding device, a ventilation pipeline, an inflation and deflation device and a control system, the rubber air bag assemblies are evenly distributed between lower frames of an aircraft, the ventilation pipeline is arranged in a maintenance channel of a lower frame of the floor, and the rubber air bag assembly is connected with the inflation and deflation device through the ventilation pipeline; during use, the rubber air bag assembly is filled with air, the top of an air bag is higher than the surface of a lower frame of an aircraft, the aircraft floor slides on the rubber air bag assembly, the electric winding device provides traction force for sliding of the floor and recovery of the rubber air bag, and the inflation and deflation device is used for inflation and deflation of the rubber air bag assembly. According to the invention, the backward conveying mode that the ultra-long aircraft floor needs to be lifted by multiple hands in a limited operation space is overcome, and meanwhile, the problem that the aircraft floor ascends and descends in an aircraft cylinder is solved.

Description

technical field [0001] The invention relates to the technical field of aircraft floor assembly, in particular to an ultra-long aircraft floor installation device and an installation method for large aircraft. Background technique [0002] The length of the main part of a large aircraft floor is about 20000mm, the width is about 4000mm, and the height is about 80mm. It is designed to be divided into three components: the left floor, the right floor and the middle floor. Each floor weighs about 500kg. Due to the long floor, the rigidity is not enough, and the shape-retaining device is not installed, it is easy to bend and deform during transportation. Existing aircraft floor installation uses an external floor transport vehicle to transport the floor to the rear fuselage door station, and inside the fuselage, the floor is transported in a way that multiple people lift the floor by hand and transfer it at the same time. It is very dangerous to stand inside the aircraft before ...

AI Technical Summary

Problems solved by technology

The entire floor installation process requires a lot of manpower and time, with a large workload and low work efficiency, and there are great hidden dangers to product quality and personal safety.

[0003] At present, there are few researches on the installation of ultra-long aircraft floors in China. There is no effective device and method available for the installation of ultra-long aircraft floors. In order to improve work efficiency and meet the needs of mass production, it is urgent to develop an ultra-long floor installation device. and installation method
