Problems solved by technology

[0002] The installation, maintenance and disassembly of the landing gear of the aircraft requires frequent handling and disassembly. The weight of a single landing gear is about 200kg. And there are certain security risks
At the same time, due to the special way of installing the landing gear, it needs to be installed on the belly of the aircraft, and the control position and attitude of the landing gear need to be flexibly changed to align with the installation holes. Therefore, general-purpose handling or lifting mechanical equipment cannot meet the use requirements.

Abstract

According to the undercarriage installation vehicle, four Mecanum wheel walking mechanisms are arranged at the bottom of a vehicle frame, a parallel four-connecting-rod lifting mechanism is arranged at the front end of the vehicle frame, one end of a lifting adjusting oil cylinder is installed on the vehicle frame, and the other end of the lifting adjusting oil cylinder is installed on the parallel four-connecting-rod lifting mechanism; one end of the pitching adjusting oil cylinder is installed on the frame, and the other end of the pitching adjusting oil cylinder is installed on the parallel four-connecting-rod lifting mechanism. The hydraulic pump is installed on the frame and connected with the lifting adjusting oil cylinder and the pitching adjusting oil cylinder at the same time. The tool cart is connected with the parallel four-connecting-rod lifting mechanism through a tool cart hanging plate. The fine adjustment mechanism is installed on the tool cart, and the undercarriage is placed on the tool cart. By means of the method, the aircraft landing gear can be installed in a mechanical mode, the labor intensity of operators in the landing gear installation process is greatly relieved, meanwhile, the operation safety risk is reduced, and the landing gear installation efficiency and the safety of the whole process are improved.

Description

technical field [0001] The invention relates to the technical field of aircraft installation equipment, in particular to a landing gear installation vehicle. Background technique [0002] The installation, maintenance and disassembly of the landing gear of the aircraft requires frequent handling and disassembly. The weight of a single landing gear is about 200kg. And there are certain security risks. At the same time, due to the special installation method of the landing gear, it needs to be installed on the belly of the aircraft, and the control position and attitude of the landing gear need to be flexibly changed to align with the installation holes. Therefore, general-purpose handling or lifting mechanical equipment cannot meet the use requirements. Contents of the invention [0003] The technical problem solved by the present invention is to provide a landing gear installation vehicle to solve the above-mentioned problems in the background technology. [0004] The te...
