Working platform for internal assembly of large aircraft fuselage

Abstract

The invention discloses a working platform for internal assembly of a large aircraft fuselage. The working platform comprises two sets of process joint assemblies, two sets of steel pipe assemblies, one set of cellular board assemblies and one set of series light rail assemblies; the process joint assemblies are symmetrically fixed to side frames on the two sides of the fuselage through hole-shaft connection of process holes on a fuselage frame, the steel pipe assemblies are symmetrically erected on process joints, the cellular board assemblies are sequentially laid on the steel pipe assemblies along the course of an aircraft to form the working platform, and the series light rail assemblies are mounted at the bottoms of the cellular board assemblies to achieve bottom hoisting of the working platform. The working platform without supporting legs is achieved through the process holes in the aircraft frame, the hoisting function in an aircraft body is achieved through light guide rails in the course direction and the spanwise direction at the bottom of the platform, the problem of repeated work of repeated building of the large aircraft working platform is solved, meanwhile, the hoisting problem in a large aircraft cylinder section is solved, and the quality and efficiency of aircraft assembly are ensured.

Description

technical field [0001] The invention relates to the technical field of assembling large aircraft fuselages in the aviation manufacturing industry, in particular to a working platform used for internal assembly of large aircraft fuselages. Background technique [0002] Aircraft technology equipment has always occupied a pivotal position in the aviation manufacturing industry, and its technical level directly affects the quality and progress of aircraft assembly. The working platform is one of the important equipment in the aircraft assembly process. The operator completes the assembly of various parts and components of the aircraft on the working platform. With the vigorous development of the aircraft manufacturing industry, aviation companies must put forward higher and newer requirements for process equipment under the dual competition of the industry and the market, and it is imperative to seek a fast and efficient work platform. [0003] The fuselage of a large aircraft ...

AI Technical Summary

Problems solved by technology

Due to the long fuselage, the process platform needs to cover the entire length of the fuselage. The number of platform plates and outriggers required is large and the weight is heavy. The ordinary crane in the workshop cannot be used inside the fuselage. The entire construction, disassembly and assembly of the floor The transportation process can only be carried by manpower, the workload is heavy, there are many repetitive tasks, and the work efficiency is extremely low
