Civil aircraft undercarriage assembling and disassembling vehicle suitable for multiple aircraft types

Abstract

The invention relates to a civil aircraft undercarriage assembling and disassembling vehicle suitable for multiple aircraft types. The civil aircraft undercarriage assembling and disassembling vehicle consists of a mobile chassis, a ball screw lifting device, a six-degree-of-freedom parallel fine adjustment mechanism, a force sensing device and a multihole detachable support. By redesign of the civil aircraft undercarriage assembling and disassembling vehicle, translation operation at any direction is realized by McKenna's wheels; large-travel lifting operation is realized by four ball screw mechanisms; multi-orientation position and attitude fine adjustment operation is realized by the six-degree-of-freedom parallel fine adjustment mechanism; assembling and disassembling work of the undercarriage of multiple aircraft types is realized by the multihole detachable support; the force sensing device is additionally arranged at the chassis part of the six-degree-of-freedom parallel fine adjustment mechanism, so that precise force control during unloading is realized; the whole assembling and disassembling process is automatically controlled. By the use of unique module structure design, the problems of single applicative aircraft type, difficulty in alignment operation, complicated operation process, low adjustment precision, low efficiency and the like of the conventional civil aircraft undercarriage assembling and disassembling vehicle are solved.

Description

technical field [0001] The invention relates to a multi-type civil aviation aircraft landing gear dismantling vehicle, which is suitable for occasions where the landing gear needs to be disassembled and assembled in civil aviation aircraft manufacturing and maintenance workshops. Background technique [0002] In recent years, with the development of the economy, my country's civil aviation industry has grown steadily. In the past 10 years, the average annual growth rate of China's civil aviation fleet has reached 10.95%. China's civil aviation maintenance industry market has also become the fastest growing civil aviation industry in the world. Aircraft maintenance market. To measure the technical level of a civil aviation aircraft maintenance unit, in addition to the maintenance capability, a very important factor is the maintenance time. Taking the Airbus 320 as an example, at present, the average maintenance time of domestic maintenance units is about 1 / 3 longer than that ...
