However, the traveling trolley 11 is not limited to such a shape, and may have an H-shape in plan view, for example. A plurality of (in this embodiment, four) running wheels 21 and 22 are mounted on the running trolley 11 . However, the number of running wheels 21 and 22 is not limited to four, but may be three or more; for example, the number of running wheels 22 may be one. The pair of traveling wheels 21 are arranged on one side of the traveling vehicle 11 in the X direction and on both sides of the traveling vehicle 11 in the Y direction.

The lifting device 13 can move the cleaning member 12 along the vertical direction (Z direction). The angle adjustment device 14 can adjust the inclination angle of the cleaning member 12 with respect to the horizontal direction (Y direction).

To explain in detail, the traveling trolley 11 has a pair of supporting members 31 and 32 erected on one side in the X direction and on both sides in the Y direction with a space between them in the Y direction. The support members 31 and 32 have the same shape and form a prismatic shape that is long in the Z direction. The pair of support arms 33 and 34 are arranged along the X direction and spaced apart from each other in the Y direction. One end of the support arm 33 in the longitudinal direction (X direction) is supported by the support member 31 so as to be movable along the vertical direction. One end of the other support arm 34 in the longitudinal direction (X direction) is supported by the support member 32 so as to be movable along the vertical direction.

That is, the support members 31 and 32 are provided with guide grooves 31a and 32a along the Z direction on surfaces facing each other. Support arms 33 and 34 are provided with guide members 33a and 34a on surfaces that do not face each other, and guide members 33a and 34a are movably supported in guide grooves 31a and 32a of support members 31 and 32, respectively.

The first drive device 35 and the second drive device 36 are, for example, drive motors provided on one of the support members 31, 32 and the support arms 33, 34, and a pinion gear rotated by the drive motor is attached to the support members 31, 32. and a rack provided on the other of the support arms 33, 34. Therefore, the first drive device 35 and the second drive device 36 can raise and lower the support arms 33 and 34 with respect to the support members 31 and 32.

In this embodiment, the guide groove 31a, the guide member 33a, and the first drive device 35 constitute a first elevating device, and the guide groove 32a, the guide member 34a, and the second drive device 36 constitute a second elevating device. Note that the first drive device 35 and the second drive device 36 are not limited to the configurations described above, and may be, for example, a ball screw mechanism, a fluid cylinder mechanism, or the like.

One end of the axis O of the cleaning member 12 is rotatably supported at the other end of the support arm 33 in the longitudinal direction (X direction). The other end of the other support arm 34 in the longitudinal direction (X direction) with respect to the axis O of the cleaning member 12 is rotatably supported. That is, the cleaning member 12 is rotatably supported between the pair of support arms 33 and 34 at the other ends of the pair of support arms 33 and 34 about the axis O. Therefore, the lifting device 13 moves the cleaning member 12 in the vertical direction by driving the first driving device 35 and the second driving device 36 to move the pair of support arms 33 and 34 in the vertical direction (Z direction). (Z direction).

The angle adjustment device 14 can adjust the inclination angle of the cleaning member 12 by varying the amount of movement of the pair of support arms 33 and 34 by the lifting device 13. That is, the angle adjustment device 14 is configured by enabling the first drive device 35 (first lifting device) and the second driving device 36 (second lifting device) to be driven independently.

That is, while the first drive device 35 is stopped by the angle adjustment device 14 and the support arm 33 is held in position, the second drive device 36 is driven to lower the support arm 34 by a predetermined distance. Then, the cleaning member 12 is in an inclined state in which the axis O is inclined at the other end (support arm 34) side with respect to the Y direction. At this time, the ends of the cleaning member 12 swing with respect to the support arms 33 and 34 by spherical bearings 39 and 40. Furthermore, when the cleaning member 12 is in an inclined state, the distance between the support arms 33 and 34 increases, but the ends of the cleaning member 12 are moved relative to the support arms 33 and 34 by the linear bushes 37 and 38. Increased distance is absorbed.

Therefore, when the cleaning member 12 is moved toward the fuselage 101 by the traveling truck 11, the cleaning member 12 is moved to the front side of the main wing 102 by steering the traveling truck 11. That is, by moving the cleaning member 12 along the extending direction XY of the main wing 102 while maintaining the parallelism between the cleaning member 12 and the fuselage 101, the intermediate portion in the longitudinal direction of the cleaning member 12 is moved to the upper surface of the main wing 102. 102a. Then, the cleaning member 12 properly cleans the upper surface 102a of the main wing 102.

When the cleaning member 12 approaches the fuselage 101 and moves to the base end of the main wing 102, the cleaning member 12 is raised to clean the upper surface 101a of the fuselage 101, as shown in FIG. That is, since the shape of the upper surface 101a of the fuselage 101 is known in advance, the control unit controls the first drive device 35 and the second drive device 36 according to the program to align the axis O of the cleaning member 12 with the upper surface of the fuselage 101.
