Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method and apparatus for mechanically cleaning large aircraft.

[Conventional technology]

Conventionally, aircraft cleaning has generally been done manually by workers, and for this reason, cleaning large aircraft such as jumbo jets requires an extremely large amount of labor and time, with about 20 workers working for 3 to 4 hours. This is a work that requires. This cleaning work must be carried out using the remaining time after maintenance work has been carried out while the aircraft is parked at the airport, so if the aircraft is parked for a short time, there is often a problem that sufficient cleaning cannot be performed. Frequent periodic cleaning of aircraft is desirable to maintain the aircraft's appearance, prevent rust, extend paint life, and improve fuel efficiency by reducing air resistance. There has been a demand for mechanization of cleaning work so that workers can complete cleaning in a short time of about one hour.

In response to such requests, devices for mechanically cleaning parts of aircraft were developed in Japanese Utility Model Publication No. 58-110600 and Japanese Utility Model Application Publication No. 1983-110600.
-126295, etc.

[Problems to be solved by this invention]

However, the conventional cleaning apparatus described above can only mechanically clean a part of the aircraft body, and a large-sized cleaning apparatus that can mechanically clean the entire aircraft body has hardly been developed. Moreover, even with the small number of large-sized washing machines that exist, cleaning the lower part of the aircraft, around the engine, around the landing gear, etc., relies on manual work, and the machine cleaning rate is low. Since these factors are not taken into consideration, there is a problem that the cleaning effect is low and the working time cannot be sufficiently shortened.

The present invention was devised in view of the above-mentioned conventional problems, and its purpose is to shorten the cleaning work time, have high cleaning effects,
Moreover, it is an object of the present invention to provide a mechanical cleaning method and apparatus with a relatively simple mechanism.

[Means for solving problems]

In the cleaning method of the present invention, an aircraft is transported into a building having a space capable of storing the entire aircraft body, and the aircraft is placed on a plurality of traveling carts guided by rails arranged on the ceiling and floor of the building. Equipped with a plurality of cleaning machines that clean specific cleaning areas that are divided into sections (described later), and these cleaning machines clean the upper part of the fuselage, the lower part of the front part of the fuselage, the lower part of the center of the fuselage, the lower surface of the main wing base, the lower part of the rear part of the fuselage, the lower part of the horizontal stabilizer, This is a cleaning method that sequentially cleans the cleaning areas divided into the upper surfaces of the vertical stabilizer/horizontal stabilizer, the upper surface of the main wing, the lower surface of the main wing, and the engine area in five stages. After cleaning the sides, the lower end of the main wing, the rear side of the upper fuselage main wing, the vertical stabilizer and the upper surface of the horizontal stabilizer at the same time, in the second stage, the lower main wing, the fuselage side, the upper center of the fuselage, the engine section, and the lower surface of the horizontal stabilizer were simultaneously cleaned. Next, in the third stage, the upper surface of the main wing, the fuselage side, and the upper surface of the head are cleaned at the same time, and in the fourth stage, the front of the upper fuselage, the lower surface of the main wing base, the lower surface of the head, and the lower surface of the fuselage diameter are simultaneously cleaned, and the fifth stage is The feature is that the center lower part of the fuselage, the lower front part of the fuselage, and the rear side of the lower fuselage main wing are cleaned at the same time.

Further, in the cleaning device of the present invention, rails are arranged on the ceiling and floor of a building having a space capable of storing the entire aircraft body, and a plurality of traveling carts guided by the ceiling rail or the floor rail are installed under the ceiling. Placed on the floor, the upper part of the aircraft's fuselage,
Front lower part of the fuselage, lower center of the fuselage, lower surface of the main wing base, lower part of the rear fuselage
Lower surface of the horizontal stabilizer, lower part of the rear fuselage, lower surface of the horizontal stabilizer, vertical stabilizer,
Multiple cleaning machines are used to clean specific cleaning areas divided into the upper surface of the horizontal stabilizer, the upper surface of the main wing, the lower surface of the main wing, and the engine area, in the longitudinal direction (X-axis direction), horizontal direction (Y-axis direction),
It is characterized in that it is provided on the traveling carriage so as to be movable in the vertical direction (Z-axis direction).

[For production]

The present invention uses a plurality of washing machines to sequentially wash an aircraft carried into a building from above to below, thereby preventing the lower part of the aircraft from becoming contaminated with the waste water used to wash the upper part (compared to conventional methods). The cleaning work time can be greatly reduced.In addition, the cleaning areas that can be cleaned by the cleaning machine are the upper fuselage, lower front fuselage, lower center fuselage, lower surface of the main wing base, lower rear fuselage/lower surface of the horizontal stabilizer, and vertical stabilizer. - Since the machine is divided into 8 areas: the upper surface of the horizontal stabilizer, the lower surface of the main wing, and the engine area, each cleaning machine does not interfere with the landing gear or engine, resulting in a very high mechanical cleaning rate.
