Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an exterior wall cleaning device that cleans the exterior walls and window glass of a building using a cleaning device installed in a gondola.

Conventionally, cleaning work for the exterior walls and window glass of buildings has been carried out by setting up scaffolding and climbing on it, or by having workers board gondolas and drive the gondolas.

However, these methods are highly dangerous when working at high places, take a long time, and are economically disadvantageous.

In addition, recently, window cleaning machines called wiping robots have begun to be used in skyscrapers, etc., but these are all designed to clean the glass in buildings that have guide rails. It cannot be used to clean the exterior walls or glass windows of buildings that have not been cleaned. Since water is still used for cleaning, the cleaning effect is low, and since the glass surface is wet immediately after cleaning, it is easy to get dirty when there is a lot of dust.

In order to eliminate the above-mentioned drawbacks, the present invention has been proposed by the present inventors (Japanese Patent Application No. 57-71626), and can be moved by pressing it against the outer wall surface without requiring any special equipment or equipment. The present invention provides a wall cleaning device equipped with a gondola equipped with a device that sprays hot water mixed with a cleaning agent onto the wall surface, scrubs the wall surface with a rotating brush, and dries the outer wall surface immediately after cleaning with warm air, The drawings will be explained in detail below.

FIG. 1 shows a cleaning equipment part according to an embodiment of the present invention, in which 1 is a gondola, 2 is a water storage tank for storing water supplied by a hose from the water supply, and 3 is a water storage tank 2 that uses propane gas as fuel.
4 is a detergent mixing chamber in which the hot water heated to an appropriate temperature by the water heater 3 is introduced and detergent is mixed by a stirring blade driven by a motor; 5 is a detergent mixing chamber in which the detergent is mixed. 9 is a movable table; 9 is a movable table; 9 is a movable table; This is the motor installed on top.

Reference numeral 10 denotes a rotating brush made of wire or nylon, which is supported by a support column on a movable base and driven and rotated by a motor 9 via a belt, and the movable base can move within the range of a long hole drilled in the movable base. , the spring 12 is always pushed toward the outer wall surface 8. Therefore, the rotating brush 1o follows the movement of the gondola 1 due to the unevenness of the outer wall surface 8 and comes into contact with the outer wall surface 8 with a constant force. Reference numeral 11 denotes a squeegee made of an elastic material such as rubber, which is attached to the tip of the movable base and has a spring 1 as in the case of the rotating brush 1o.
2', it is always pressed against the outer wall surface 8. 13 is a heater, and 14 is a plurality of blowers 14 arranged in a row behind the heater 13, and these heaters 13 and blowers 14 form a hot air blower for drying the wall surface which blows hot air onto the outer wall surface 8. . 15 is a cleaning liquid scattering prevention wall that covers the back and both sides of the gondola 1; 16 is a water collection spatula such as a comb provided at the tip of the partition; 17 is a water collection groove formed between the partitions on both sides; 18
1 is a drainage hose that drains water accumulated in the water collection groove 17, 19 is a drainage pump, and 2o is a drainage groove. 21 is a filtration chamber that filters the water when the water collected in the water collection groove 17 is reused without being drained; 22 is a storage tank 2 for storing the filtered water in the filtration chamber;
This is a room in which a pressure pump is installed to send water to the plant via a hose 23. Reference numeral 24 designates an arm that protrudes from the back surface of the gondola 1 and has a pulley 25 at its tip to which a gondola hanging wire rope 26 is hung, and 27 represents a rotating body such as a caterpillar.

Wheels may be used instead of caterpillars.

FIG. 6 shows an overall schematic diagram of an embodiment of the present invention, in which 28 is a wire rope driving device placed on the ground, 29 is a horizontal moving device attached to the top of the outer wall, and 3° is a horizontal moving device 28. It is a pulley supported by the arm of the Horizontal movement device 29
The cleaning position can be changed in the horizontal direction by simultaneously moving the wire rope drive device 28 consisting of a winch placed on the ground. The angle of the wire rope 26 is varied so as to be inclined toward the wall surface above and below the arm 24 protruding from the gondola 1. Therefore, of the resultant force of the tension of the wire rope 26 above the arm 24 and the tension of the wire rope 26 below the arm 24, the horizontal component acts as a force pressing the gondola 1 against the wall surface (the gondola 1 The larger the weight of the wire rope 26 and the larger the angle between the twisted wire rope 26 and the vertical line, the stronger the force that presses the gondola 1 against the outer wall surface 8.

Cleaning by the device of the present invention involves moving the gondola 1 from above to below using a drive device, storing water from a tap etc. in a water storage tank, sending the water to a hot water room, and using propane gas as fuel in the hot water room. The heated hot water is heated to the required temperature with a gas burner, and the mixed solution with detergent is mixed in a detergent mixing tank 4 equipped with a stirring blade driven by a motor, and the mixed solution is sent under pressure to the cleaning liquid blowing pipe 7 using a pump in a pumping chamber 5. Then, the cleaning liquid is sprayed onto the outer wall surface 8 from the hole of the blow-off pipe 7.

Next, the outer wall surface 8 covered with the cleaning liquid is rubbed with a rotating brush 10. Thereafter, moisture is wiped off with a squeegee 11, and then warm air heated by a heater 13 is applied to the outer wall surface 8 using a blower 14 to dry it.

Is the cleaning liquid dripping from the outer wall surface 8 collected by the water collection spatula 16?
f41.7 and drained through the drain hose 18, or filtered through the filter device 21 and reused. The type of detergent, cleaning method, cleaning cycle, etc. for exterior wall finishing materials, window glass, etc. differ depending on the material. Therefore, use a detergent and brush appropriate for the material of the object to be cleaned, and depending on the material, it may be necessary to remove the squeegee 11. Let's do it.

As described above, according to the device of the present invention, heated water mixed with detergent is sprayed onto the outer wall surface and then rubbed with a rotating brush, so the cleaning effect is great. Since it is always pressed against the wall surface, it moves to follow the unevenness of the outer wall surface, and since it blows warm air on the outer wall surface immediately after cleaning, even if the wall surface is dry and there is a lot of dust, it will not stick to it. In addition, the gondola is pressed against the wall from the back side by a wire lobe operated by a drive device installed on the ground, so even without guide rails, the gondola can stably maintain the height of the building without moving away from the wall due to wind pressure etc. The cleaning work of the outer wall surface of a place can be carried out unattended, quickly and safely.
