A gondola 3 is suspended from the lower end of the wire 2 wound around the wire 2 .

The gondola 3 is composed of a box-shaped gondola main body 11 that houses various cleaning equipment, a vacuum pump, etc., and a rectangular support frame 12 that is integrated with the upper part of the gondola main body 11.

On the left and right sides of the gondola body 11, a cylinder device 13 equipped with a telescopic piston 13a is provided on the side of the building A, and each piston 13a has a suction cup 14 connected to a vacuum pump mounted on the gondola body 11. is attached, the piston 13a is expanded and contracted to bring the suction cups 14 into contact with the exterior wall surface C of the building A, and the air inside each suction cup 14 is removed by a vacuum pump, so that the suction cups 14 are brought into contact with the exterior wall surface C of the building A. The gondola main body 11 can be fixed by adsorption to the. A sensor 17 for detecting the distance between the gondola body 1 and the outer wall surface C is provided on the front surface of the gondola body 11 facing the building.

On the other hand, as shown in FIG. 3, the support frame 12 has a horizontal bar 15 that is movable up and down by a rack and pinion mechanism (not shown). A movable body 16 is provided so as to be movable left and right, and a cleaning unit U is attached to this movable body 16 as shown in FIG. 2.

The cleaning unit U is installed in a building A, as shown in FIG.
A pair of upper and lower guide rollers 24.24 supported by the support arm 20 is provided on the side closer to the
．． A take-up roll (take-up mechanism) 22 and a supply roll 2 are supported by a support arm 20 on the rear side of 24 (right side in FIG. 1).
A flat bag-shaped pad P is vertically supported between the upper and lower guide rollers 24.24 by a spring (pressing mechanism) 26.26 attached to the support arm 20. Since this pad P is made of a flexible material such as resin, its inside is filled with fluid such as gas, and its surface is made of tetrafluoride ethylene to reduce friction with a cleaning cloth 27 (described later). coated with a material with a low coefficient of friction such as (trade name: Teflon), or
A low-friction material is attached. Then, the winding roll 2
A belt-shaped cleaning cloth 27 is wrapped around the upper and lower guide rollers 24, 24, and the supply roll 23.
7 is an upper and lower guide roller 24°2 by the pad P.
4, it is biased slightly forward (the side closer to building A). The rotation shafts of the take-up roll 22 and the supply roll 23 are connected to a motor along the path shown in the figure, and the cleaning cloth 27 is moved from the supply roll 23 to the take-up roll 2 at a required speed as needed.
It can be rolled up in two. Note that the reference numeral 28 in FIG. 1 is a handle attached to the support arm 20.

The cleaning unit U having the above configuration is attached to the movable body 16 of the flat surface cleaning apparatus S with the guide rollers 24, 24 facing the building A side, as shown in FIG.

Next, the operation of cleaning the outer wall surface C of the building A using the cleaning unit U having the above-described configuration will be explained.

The height of the gondola 3 is adjusted by letting out the wire 2 of the flat cleaning device S, and once the cleaning unit U is opposed to the outer wall surface C to be cleaned, the gondola 3 is fixed with the suction cups 14 and 14, and the winding The cleaning cloth 27 is wound up by the take-up roll 22. This operation causes the cleaning cloth 27 to move upward between the guide rollers 24, 24 as shown by the arrow in FIG. Subsequently, the piston 13a is extended to press the cleaning cloth 27 against the outer wall surface C of the building A.

When the cleaning cloth 27 comes into contact with the outer wall surface C, the spring 26.2
6, the pad P uniformly presses almost the entire surface of the cleaning cloth 27 between the guide rollers 24 and 24 against the outer wall surface C.

By moving the cleaning cloth 27 in this state, the outer wall surface C is wiped and cleaned. Note that even if the outer wall surface C has some unevenness, the pad P brings the cleaning cloth 27 into close contact with the unevenness of the outer wall surface C, so that dirt on the uneven outer wall surface C can be thoroughly removed. Further, by moving the horizontal bar 15 up and down and moving the movable body 16 left and right, the cleaning unit U can be moved up and down and left and right to clean a desired position on the outer wall surface C.

When cleaning of the outer wall surface facing the support frame 12 is completed, the wire 2 is let out or pulled up to move the gondola 3 to a required height, and the same cleaning work as described above is performed at another position. By repeating the above-mentioned work, the cleaning work of the outer wall of the building is performed.

That is, if the cleaning unit U having the above configuration is used to clean the exterior wall surface C of the building A, the cleaning cloth 27 can be brought into close contact with the exterior wall surface C to wipe the exterior wall surface C, which is the same as manual cleaning. The cleaning work can be performed with a certain level of quality, the practicality of the flat surface cleaning device S can be improved, and the mechanization of cleaning work on the outer wall surfaces of buildings can be realized.

Incidentally, the inside of the pad P can also be filled with a liquid 30 as shown in FIG. Furthermore, as shown in FIG. 5, the pad P° can be constructed by dividing the interior into a plurality of small chambers 31.

``Effects of the Invention'' As explained above, the present invention enables cleaning by wiping while pressing the cleaning cloth evenly against the outer wall surface of the building with the pad, making it adhere to the outer wall surface of the building. You can do it without using it. In addition, even if the outer wall surface has some unevenness, the pad presses the cleaning cloth all over the outer wall surface, so the outer wall surface including the uneven parts can be finished well (cleaned).
