Civil aircraft wheel automatic lifting device and using method thereof

Abstract

The invention belongs to the field of airport aviation ground special equipment, and particularly relates to an automatic civil aircraft wheel lifting device and a using method thereof. The device comprises a movable and tractable main lifting platform which is used for realizing vertical lifting of airplane wheels; a movable auxiliary lifting platform which is used for realizing vertical lifting of the airplane wheel shaft; and a double-four-bar mechanism which is used for connecting the main lifting platform and the auxiliary lifting platform. The beam structure is used as a basic framework, so that the manufacturing cost is saved while enough rigidity and strength are ensured. On the other hand, the invention further provides a structural form of combining the main lifting platform and the auxiliary lifting platform of the automatic lifting device for the airplane wheels, a wheel holding type lifting mechanism of a traditional tractor is replaced by the U-shaped cantilever supporting table, the operable space of maintenance personnel is enlarged, maintenance is convenient, and meanwhile, flexible conversion of traction transfer of the airplane and lifting overhaul of airplane wheels can be achieved, the operation procedures are simplified, and waste of equipment resources is avoided.

Description

technical field [0001] The invention belongs to the field of airport aviation ground special equipment, and in particular relates to an automatic wheel lifting device for civil aviation aircraft and a use method thereof. Background technique [0002] Aircraft tires mainly serve as ground support and landing buffer for the aircraft. Especially at the moment of aircraft landing, the wheels are prone to wear and tear or even tire blowout under the conditions of strong impact, strong friction, high temperature and high pressure, which seriously affects the safety of aircraft operation. Therefore, during the operation and maintenance of civil aviation aircraft, the wheels of the aircraft need to be overhauled frequently. When the aircraft has a puncture or other failures and cannot drive by itself, it is necessary to quickly tow the faulty aircraft off the runway to avoid large-scale flight delays. [0003] At present, the front wheels of the aircraft are mainly picked up by the ...

Problems solved by technology

However, the cost of aircraft tractors is high, about 2 to 4 million per unit. With the increase of flights, the scheduling of aircraft tractors is tense. If they are arranged to lift and tow small aircraft for a long time, resources will be wasted; the operation of tractors requires Full-time maintenance personnel have high requirements for operation level; the wheel holding mechanism of the aircraft tractor has a small space, and can only carry out lifting and traction operations on the wheels, and there is no operating space for further maintenance of the tires. In addition, special aircraft wheel maintenance lifting equipment is used. , for some simple wheel maintenance work, the process is complicated and resources are wasted
