Spraying robot

The invention discloses a spraying robot which comprises a winch system, a robot body and a mobile control terminal, a tilt angle sensor is arranged on the robot body, and a steel cable of the winch system is connected and dragged through a hook lock arranged on the robot body. Omni-directional driving wheel sets and universal driven wheel sets are symmetrically arranged on the periphery of the face, facing a spraying working face, of the robot body, and under the traction effect of a steel cable, data of a tilt angle sensor serve as the basis in real time, so that the robot body is helped to achieve the transverse moving function and the vertical maintaining function; the robot body is adsorbed to the spraying working face through the matched negative pressure fan set, the spraying distance and spraying equipment are kept stable, and meanwhile the effects of promoting air circulation at the spraying working face and accelerating air drying are achieved; a mobile control terminal and an electric control cabin
