PURPOSE:To miniaturize a wall surface peel-off device and to enhance the efficiencies of water injection and retrieval of a layer to be peeled off by arranging a vacuum chamber on one side surface of a robot body facing a wall surface, by arranging a sucker ring at the outer peripheral part of an opening, and by storing a water jet nozzle in the vacuum chamber. CONSTITUTION:A robot 1 is suspended by a pair of automatic tension winches which are not shown, and is self-traveled on a wall surface by means of a plurality of wheels 22 each incorporating a drive source. In this case, a vacuum chamber 11 having an opening 12 is arranged on one side surface l0a of the body part of the robot 1 facing the wall surface. Further, a sucker ring 13 is arranged in the outer peripheral part of the opening part 12. Further, a water jet 32 which is communicated with the front end of a water supply pipe which is air-tightly inserted into the body from the other side surface of the body part and which is not shown is disposed in the vacuum chamber 11, and which is adapted to jet high pressure water toward the wall surface. That is, a water jet nozzle 32 is stored in the inside of the sucker ring 13. |
