Demolding lifting device specially used for skin of aircraft

Abstract

The invention relates to a demolding lifting device specially used for a skin of an aircraft. The demolding lifting device comprises a truss trolley, a frame, an electric control cabinet, a hanging bracket, flexible adsorption mechanisms, a protection mechanism, positioning POGO columns and locking POGO columns. The truss trolley is located above the frame and is in hanging connection with the frame. The electric control cabinet and the hanging bracket are installed on the frame. The electric control cabinet is in control connection with the flexible adsorption mechanisms, the positioning POGO columns and the locking POGO columns. A preset number of the flexible adsorption mechanisms are arranged at the bottom of the hanging bracket. The protection mechanism is arranged at the bottom of the frame in a gear rack transmission manner and can move in the length direction of the frame. The positioning POGO columns are arranged at the four corners of the bottom of the frame. The locking POGO columns are arranged in the middle of the bottom of the frame in pairs. The demolding lifting device can realize demolding and lifting of ultra-large ultra-long skins.

Description

technical field [0001] The invention relates to a demoulding device, in particular to a demoulding and lifting device specially used for aircraft skin, and belongs to the technical field of aircraft assembly. Background technique [0002] It is well known that the aircraft skin is the outer part that constitutes the aerodynamic shape of the aircraft. It has large size, complex and diverse shapes and small batches, and is an important part to ensure the aerodynamic performance of the aircraft. In the process of aircraft assembly and manufacturing, it is necessary to demould and lift the skin. Due to the poor rigidity and small thickness of the skin, it is easy to deform during the process of demoulding and lifting. [0003] At present, most of them adopt the traditional manual demoulding lifting method and the general lifting device in the civilian market. However, when faced with skins with structural characteristics such as oversized and long lengths, the traditional manua...

AI Technical Summary

Problems solved by technology

However, when faced with skins with structural characteristics such as oversized and long lengths, the traditional manual demoulding and lifting methods are not suitable for this type of skins; and the lifting devices on the civilian market are in terms of product adaptability, safety, It is difficult to meet the lifting requirements of this type of skin in terms of main technical indicators such as the degree of automation
