A large-scale landing gear flexible installation and storage dual-purpose device

Abstract

The invention relates to a flexible installation and storage two-purpose device for a large undercarriage. The flexible installation and storage two-purpose device comprises a device main body provided with an undercarriage bearing cavity; a shock strut flexible support mechanism and an airplane wheel fixing mechanism are respectively arranged in the upper end and the lower end of the undercarriage bearing cavity; the shock strut flexible support mechanism comprises a check ring assembly, adjusting screw rods and air cylinders; the check ring assembly is arranged in the upper end of the undercarriage bearing cavity in a suspending manner through the air cylinders and the adjusting screw rods; the air cylinders are positioned on the left and right sides of the check ring assembly, and two ends of each air cylinder are respectively connected with the check ring assembly and the device main body; the adjusting screw rods are positioned on the left, right and back sides of the check ring assembly; one end of each adjusting screw rod is connected with the check ring assembly, and the other end of each adjusting screw rod is arranged on the device main body in a penetrating mode and is fixedly locked through an adjusting hand wheel; the airplane wheel fixing mechanism comprises three groups of fixing assemblies which are respectively arranged on the left, right and back sides of the device main body. Therefore, the installation angle of the undercarriage can be adjusted accurately by freely adjusting the check ring assembly in six degrees of freedom, the operation is easy, convenient and quick, and the installation efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of general aircraft production, in particular to a dual-purpose device for flexible installation and storage of large landing gear. Background technique [0002] With the development of science and technology, the tonnage of aircraft continues to rise, and the structure of the landing gear that carries the weight of the aircraft is also getting larger and more complex. The weight often exceeds 1 ton, and the installation space is limited. However, at present, the existing domestic tooling for the installation of large-tonnage aircraft landing gear generally uses rigid installation vehicles, which makes it very difficult to adjust the installation angle, and the general installation adjustment is completely dependent on manual labor, repeated labor, and the moving position is unstable and inaccurate. Affects the quality and speed of installation. Contents of the invention [0003] In order to solve the abo...
