Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention provides a suction system suitable for securely fixing a wall-moving work machine to a concrete surface or tile surface with uneven vertical exterior walls such as high-rise buildings. It is related to the device.

[Background of the invention]

As described in Japanese Patent Publication No. 60-28715, there is a conventional device of this type that adsorbs to a wall surface surrounded by gas or liquid and moves along it.

This device prevents the seal part in contact with the wall surface from being deformed by protrusions such as welding beats on the wall surface as the device moves, thereby preventing the airtight contact between the seal portion and the wall surface from being broken. However, there was no consideration given to adhesion to particularly uneven walls such as concrete and tile surfaces.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a suction device that can reliably fix a wall-moving work machine even to a wall surface with an extremely uneven wall surface such as a concrete surface or a tile surface.

[Summary of the invention]

In order to achieve the above object, the present invention provides a wall-moving work machine that is fixed on an fffl wall surface by the vacuum suction force of a vacuum suction device and that moves on the wall surface to perform work. and a vacuum generator connected to each of these vacuum chambers.

[Embodiments of the invention]

An embodiment of the apparatus of the present invention will be described below with reference to the drawings.

1 and 2 show the overall configuration of a wall-moving work machine equipped with the suction device of the present invention, and the wall-moving work machine is a hanging unit such as a crane installed on the roof of a high-rise building 5. 1 and a mobile unit 2 suspended along a vertical wall surface by wires 3. The moving unit 2 includes a plurality of (four in this embodiment) vacuum suction devices, such as vacuum suction pads 4, and a work unit 6 equipped with tools for cleaning, adhering, etc. the wall surface.
The work unit 1-6 is supported so as to be movable in the left and right directions in the figure,
It is composed of a horizontal movement mechanism 7 equipped with a ball screw, a guide, and a drive machine, and a vertical movement mechanism 8 that supports the work unit 6 so as to be movable in the vertical direction shown in the figure and equipped with a ball screw, a guide, and a drive machine. ing.

FIG. 3 is a sectional view showing the vacuum suction pad 4 of the vacuum suction device attached to the moving unit 2. The vacuum suction pad 4 is attached to the main body 9. Flange 10. An inner pad member 11° made of a circular elastic material such as soft rubber forming an inner vacuum chamber 11'; an outer pad member 12 made of a circular elastic material similar to the above-mentioned material forming an outer vacuum chamber 12'. The inner vacuum chamber 11' and the outer vacuum chamber 12' are formed separately, and these vacuum chambers 11' and 12' are connected via passages 13°14 to 15. Vacuum generators such as vacuum pumps and vacuum pumps.
Next, the operation of the device of the present invention connected to 16 will be explained.

First, the mobile unit 2 is suspended by the hanging unit 1 and moved to a predetermined position on the vertical wall surface of the high-rise building 5, and then the mobile unit 2 is fixed to the vertical wall surface using a plurality of vacuum suction pads 4. At this time, even if the vertical wall surface has an uneven surface such as a concrete surface or a tile surface, the moving unit 2 is reliably fixed to the wall surface by the vacuum suction force of the vacuum pad 4. That is, vacuum chamber 11' and vacuum chamber 12
' are separated and connected to the respective vacuum generators 15 and 16, so even if there are joints or cracks in the tiles in the outer vacuum chamber 12', the By blocking and sealing joints and cracks, suction force can be generated in the inner vacuum chamber 11'.
The moving unit 2 can be reliably fixed to the wall without reducing the adsorption force to the wall.

Returning to the front, when the fixation of the moving unit 2 to the wall is completed, the working unit 6 operates the horizontal moving mechanism 7 or the vertical moving mechanism 8, and the working unit 6 is moved to a predetermined position by the ball screw connected to the drive machine. Move it to the position and perform cleaning work on the wall surface.

FIG. 4 shows another embodiment of the device of the present invention.

Vacuum suction pad member 12 forming an outer vacuum chamber 12'
A sealing member 17 such as a circular elastic body such as a sponge is provided on the outer peripheral side of the vicinity.

By providing the seal member 17 as described above, the inner pad member 11. Even if there are severe irregularities on the wall surface that cannot be sealed with the outer pad member 12, the sealing member 17 prevents gaps by responding to the uneven surface, so the moving unit 2 can be securely attached to the wall surface without reducing the suction force. Can be fixed.

〔Effect of the invention〕

According to the device of the present invention, it is possible to reliably fix a wall moving work machine even to a vertical wall surface such as a concrete surface or a tile surface having an uneven wall surface condition.
