Description

DETAILED DESCRIPTION OF THE INVENTION (Related Field) The present invention relates to a body cleaning device for an aircraft having a three-dimensionally complex shape.

(Prior art) Aircraft bodies are easy to replace and have complex shapes.
Automation of cleaning has been hampered, and cleaning is still carried out by human labor.

(G point) An object of the present invention is to provide an automatic cleaning device that can freely clean the complicated shape of the aircraft body. More specifically, the present invention aims to provide an automatic cleaning device equipped with an articulated cleaning head that performs the same function as a human hand.

(Summary of configuration) Multiple frames are rotatably connected using cylinders,
Moreover, the connected frames are arranged symmetrically in a JJJ pattern, the center base of which is supported by a large cylinder so as to be expandable and contractible, and each frame 11 is provided with a cleaning nozzle, a cleaning liquid cutting nozzle, etc., thereby making it possible to create a complex aircraft body. It is characterized in that it can be shaped into any shape to clean the entire body of the aircraft.

(Example) In FIG. 1, ■ is an aircraft maintenance building, and 2 is an aircraft to be cleaned. Reference numeral 3 denotes an overhead truck, on which a cleaner head 4 is movably mounted. Reference numeral 5 denotes rails of the truck 3, along which the truck 3 can move in the longitudinal direction of the aircraft 2. Cleaner head 4 has cleaning
The rad 6 is suspended so as to be able to turn and move up and down, and can also be moved in the rlJ direction of the aircraft 2 as the cleaner head 4 travels.

Referring to FIG. 2, the cleaning head 6 is constructed symmetrically with a plurality of frames 8, and each frame 8 is rotatably connected via a pivot pin 9. As shown in FIG.

Further, each frame is provided with a cylinder 7a as a means for rotating each frame 8 around the pivot pin 9.
The individual frames can be freely rotated by expanding and contracting the cylinder 7a. Furthermore, the frame 8 is formed in the shape of a circular arc, which is slightly larger than a semicircle, as shown by the solid line in FIG. It can be expanded and contracted to match the shape of the fuselage 2 as shown in FIG.

FIG. 3 is a view from the ■-■ arrow in FIG. 2. The frame 8 constituting the cleaning head 6 is equipped with a cleaning nozzle 14, a cleaning liquid cutting nozzle 15, and a sensor 1G.
and frame 8 can be controlled to be at a constant distance.

Although this example is equipped with a cleaning nozzle 14, a cleaning liquid cut-off nozzle 15, and a sensor 16, the cleaning head 6 can also be equipped with a painting nozzle depending on its purpose, and these can be used properly depending on the purpose of use. be able to. Alternatively, it can also be equipped with multiple multi-purpose nozzles,
Furthermore, it can also be equipped with a 1li-Li nozzle suitable for the purpose. W in the figure is a balance weight.

It should be noted that the supply pipelines for the cleaning water and the like to the cleaning nozzles and the like can be provided by any means such as passing through each frame 8 or by installing piping in the frame 8.

In this example, the cleaning head 6 is installed on the overhead truck 3 and the cleaning head truck 4, but the cleaning head 6 is installed on the overhead truck 3 and cleaning head truck 4.
It may be mounted on a moving vehicle 17 running on the ground as shown in the figure. That is, by mounting it on a boom 18 that is provided on a swing base on a moving vehicle 17, is extendable and retractable, and can be tilted by a cylinder 19, the same movement as described above is possible.

In addition to cleaning, it can also be used for painting and removing paint using high-pressure water, and can be used not only for cleaning aircraft bodies but also for other multipurpose purposes.

(Effects) According to the present invention, a plurality of frames are rotatably connected by cylinders, and these connected frames are provided symmetrically, and the multi-jointed structure allows expansion and contraction by a large cylinder at the center. , it is possible to easily follow the shape of a complex shaped aircraft.

Therefore, by attaching a cleaning nozzle, a cleaning liquid cutting nozzle, etc. to each frame, it is possible to easily perform three-dimensional movements similar to a human hand, making automatic cleaning extremely easy.
