PURPOSE:To remotely perform, on the floor, inspection work of damages, stains and so on of a ceiling installed at a high position so as to prevent any danger, and providing a suction tool for ejecting gas to generate suction force in the case of a large distance from the ceiling while repulsive force in the case of a small distance therefrom. CONSTITUTION:A suction tool A constituted of a gas supply port 1, through which high pressure gas C is introduced, a bowl-like base portion B having an opening at the lower portion thereof and an operating surface 5 at the lower end is mounted on a mount table 9 to which a damage sensor or the like is fixed. The high pressure gas C is introduced into the gas supply port 1 through a pipeline 7. When the operating surface 5 approaches a ceiling G, a space defined between the surface 5 and the ceiling G functions as a diffuser of an ejector; a cushion chamber 4, as a vacuum chamber; and the gas supply port 1, as a nozzle. Therefore, a dangerous inspection work of damages, stains and so on of the ceiling installed at a high position can be performed remotely on the floor. |
