An aircraft assembly work dock

Abstract

An airplane assembling dock is a combined modularized assembling platform comprising two airplane body front section modules, , two wing body front section modules, two wing body back section modules, two nacelle external modules, two wing modules and two empennage module all in a left-right symmetric way and serially connected; Each module is formed by an independent supporting framework, a work platform, a movable truckle and a fixing support leg; after modular assembling, a plurality of through work platforms close to the airplane external work positions can be formed; when the airplane is parked, all modules get close to the airplane body; an overall airplane assembling dock is formed after docking work; and when the airplane assembling work is finished, the movable work dock can meet demands for overall displacement of the airplane.

Description

technical field [0001] The application relates to the technical field of aircraft manufacturing, in particular to ground equipment for aircraft general assembly, and an aircraft assembly work dock. Background technique [0002] In the aviation manufacturing industry, the design and manufacture of aircraft technology and equipment has always occupied a pivotal position, and its technical level directly affects the aircraft assembly quality and model development progress. As a traditional aircraft manufacturing and assembly tooling, the ground equipment working ladder is spread all over the major workshops of aviation enterprises, runs through the entire aircraft manufacturing process, and plays an indispensable role in the model development. With the vigorous development of the aircraft manufacturing industry and the gradual marketization of the aviation industry, aviation companies must put forward higher requirements for the quality of process equipment under the dual compe...

Problems solved by technology

The repeated placing and evacuation of tooling seriously reduces the work efficiency of workers

And in the process of use, each working ladder can only take into account a very small working area, there is no passage between the working ladders, and the operator has to shuttle back and forth between the working ladders, which also wastes a lot of physical strength and time, resulting in work Low efficiency and long aircraft assembly cycle

Due to the limited area of ​​the work ladder, there will be certain hidden dangers to the safety of personnel.

At the same time, the risk of tooling colliding with the aircraft during the movement also increases accordingly, and these working ladders occupy a large area of ​​the workshop, resulting in limited workshop space

In addition, the manufacturing process is backward, the material selection is outdated (welded steel pipes), and the work ladder produced is relatively heavy, poor in mobility, and has a very unattractive appearance, which is out of place in the modern factory buildings of aviation companies

It is very laborious for the operator to move the small working ladder, while the large working ladder needs to be driven by other external forces such as electric or pneumatic drive, resulting in a substantial increase in tooling costs, which is not conducive to the control of the entire aircraft production cost

[0004] In view of the above, in order to improve the scattered distribution of working platforms of aircraft working ladders and the low efficiency of use, improve product quality, and ensure the safety of personnel, it is necessary to develop a light-weight, easy-to-manually-movable, fast-assembled elevator for aircraft general assembly work. Can form a smooth aisle, safe and reliable, low cost, cost-effective assembly work dock to better meet the needs of aircraft assembly
