面作業機の揺れ止め装置。 An endless belt that rolls on a work wall by being wound around a pair of rollers attached above and below in the vertical direction of a wall work machine that is driven up and down along the work wall, and has a plurality of adsorption recesses formed on its outer peripheral surface. and a plurality of vacuum tubes, one end of which is attached to the inner peripheral surface of the endless belt so as to communicate with each suction recess of the endless belt, and the other end of each vacuum tube rotates in synchronization with the rotation of the endless belt. A rotary valve that is attached to the outer circumferential surface of the rotary body and which connects the vacuum port of the central fixed body with which the circumferential surface of the rotary body slides and connects each vacuum tube sequentially through the rotation of the rotary body, and a suction recess in the endless belt that is in contact with the work wall surface. A swing prevention device for a wall working machine, comprising a vacuum suction mechanism that sucks the inside of the machine through a rotary valve and a vacuum tube to vacuum-adsorb an endless belt to a work wall surface.
