Injected from. When the switching valves 130 and 131 are turned off,
The pressurized air of the compressor 121 is supplied to each of the nozzles 111 and 112 via the branch path of the air supply path 122, and air is jetted from the nozzles 111 and 112.

(Use of High Place Cleaning Machine) In the high place cleaning machine 1, the insertion column 6 b is pulled out of the fixed column 6 a of the base 5 and disassembled, and the arms 31, 32 and the feeding device 3 are moved along the column 6. If folded as above, it can be carried as a single long bundle of objects.

At the cleaning site, the cleaning machine is assembled, and the feeding device 3 supports the cleaning device 1. And hoisting machine 2
6, the lifting device 7 is raised, and the screw jack 33 of the lifting device 8 is actuated to raise and rotate the arms 31 and 32, thereby raising the cleaning device 1 together with the feed device 3 to increase the cleaning site. It will be positioned on the ceiling.
In addition, the use of the left and right outriggers 13 increases the stability of the cleaning machine.

Rotating disk brush 5 of brush-type cleaning tool 45
When the cleaning device 1 is moved forward while the supply of detergent liquid / wash water and the supply of pressurized air are alternately repeated by rotating the first and the 51st, the ceiling surface is wiped by the fixed brush 62,
The cleaning is performed by the rotating disk brushes 51, 51. At this time, the two rotating disk brushes 51, 51 rotate in directions opposite to each other, so that the rotational vibration of the rotating disk brushes 51, 51 and the vibration of the entire cleaning device 1 are reduced.

When the cleaning device 1 advances, the pinion 83 of the cleaning cloth 46 is lowered and meshed with the rack 82, so that the pinion 83 rotates with the advance, and the rotation is controlled by the chain transmission device 84 and the gear. The rotation is transmitted to the front clamping roller 81 via 97 and 99 and rotates. Since the three nipping rollers 81 are urged against each other by the spring 94, the band cloth 72 nipped by the nipping rollers 81 travels in the direction indicated by the arrow.

The moving speed of the band cloth 72 is different from the moving speed of the cleaning device 1, so that the ceiling is rubbed with the band cloth 72 to remove dirt. In this case, since the band cloth 72 moves following the rotating disk brush 51, the ceiling surface which is cleaned by the rotating disk brush 51 and remains moisture is rubbed by the band cloth 72 and the dirt is wiped cleanly with the water. Will be taken.

When the cleaning device 1 has advanced to the tip of the rail 36, the pinion 83 is raised to disengage with the rack 82, and the reversing drive motor 104 is operated. Invert. Therefore, if the cleaning device 1 is sent to the base end side of the rail 36, the ceiling can be cleaned by the rotating disk brush 51 and the rag 72 in the same manner as in the previous case.

When a part of the ceiling is cleaned by advancing or reciprocating the cleaning device 1 and then cleaning the adjacent part, the entire cleaning machine can be moved laterally together with the left and right outriggers 13. By rotating the handle 22 and moving the base 5 right or left while the base 5 is supported by the left and right outriggers 13, 13, the cleaning device 1 can be easily positioned at the next cleaning place. In particular, when cleaning the ceiling near the wall, the left and right outriggers 13 interfere with the wall, so that the entire cleaning machine cannot be laterally moved together with the left and right outriggers 13.
With the operation handle 22, only the base 5 can be easily moved toward the wall.

In the case of the ceiling of the staircase hall at the cleaning place, the horizontal beam 12a of the front outrigger 12 is extended, and the vertical beam 12b is attached to the horizontal beam 12a.
Will be supported on the landing while the vertical beam 12b will be grounded to the down stair step.
