Embodiment Construction

[0034] A method for removing a panel assembly at an aircraft cargo door includes the following steps:

[0035] Step 1: Assembling, assembling the panel parts after the assembly positioning and hole making into the panel assembly 2 on the assembly tool 1;

[0036] Step 2: Installing, installing and fixing the shape-preserving tool 3 on the wall panel assembly 2, and the shape-keeping tool 3 is connected and fixed to at least four different parts on the wall panel assembly 2;

[0037] Step 3: connecting, connecting the lifting tool 4 with the shape-conserving tool 3 through the sling 42;

[0038] Step 4: Take off the shelf, firstly lift the lifting tool 4 vertically to make the sling 42 in a tensioned state, then take out the positioning pins to separate the wall panel assembly 2 from the assembly tool 1, and then move the lifting tool 4 horizontally to make the lifting The shape-preserving tooling 3 connected with the tool 4 drives the panel assembly 2 to move out from the ass...

Abstract

The invention discloses a method and a tool for unloading wall panel assemblies at cargo space doors of airplanes. The method for unloading the wall panel assemblies at the cargo space doors of the airplanes includes steps of firstly, assembling assembled, positioned and perforated wall panel components on assembling tools to obtain the wall panel assemblies; secondly, fixedly mounting shape preserving tools on the wall panel assemblies and at least fixedly connecting each shape preserving tool with four different positions on the corresponding wall panel assembly; thirdly, connecting hoisting tools with the shape preserving tools by hang ropes; fourthly, unloading the wall panel assemblies, to be more specific, vertically lifting the hoisting tools to enable the hang ropes to be in stressed tightened states, taking out positioning pins to enable the wall panel assemblies and the assembling tools to be in separated states, and horizontally shifting the hoisting tools to enable the shape preserving tools connected with the hoisting tools to drive the wall panel assemblies to be shifted out and unloaded from the assembling tools. The method and the tool have the advantages that the steps of the method are simple, the tool is high in work efficiency, and problems of deformation, scratching or breakage of hoisting bolts and the like due to the fact that existing wall panel assemblies are integrally unloaded can be solved.

Description

technical field [0001] The invention relates to a method and a tool for unloading, in particular to a method and a tool for unloading a panel assembly at an aircraft cargo door. Background technique [0002] In the domestic civil aircraft manufacturing industry, especially the conversion of passenger aircraft into cargo aircraft, issues such as assembly, removal, and lifting of panel components at the cargo door of the aircraft are often involved. The panel assembly is one of the components of the cargo aircraft fuselage and is located around the cargo door of the cargo aircraft. It is an aircraft component specially designed and manufactured to strengthen the structure around the cargo door after the passenger aircraft is converted into a cargo aircraft. The unloading of the panel assembly at the cargo door of the aircraft refers to the process of removing the panel assembly from the assembly tool. [0003] Since the panel assembly is a special skin structure with a "C"-sh...
