The invention is applicable to the technical field of wall-
climbing robots, and provides a derusting wall-climbing
robot for a ship. The derusting wall-climbing
robot aims at providing the technical problem that in the prior art, an existing derusting wall-climbing
robot for the ship is poor in obstacle climbing capacity. The derusting wall-climbing robot for the ship comprises a washing plate, a
caterpillar track making contact with the wall face of the ship, a drive
assembly, a driven floating
assembly with driven wheels, a floating connection
assembly driving the washing plate to automatically move up and down relative to the wall face of the ship, and a pressing assembly providing pre-pressing force so as to press the
caterpillar track. According to the derusting wall-climbing robot for the ship, driving wheels are driven by the drive assembly to drive the driven wheels to move, and therefore the
caterpillar track is driven to walk on the wall face of the ship; when the derusting wall-climbing robot encounters obstacles in the walking process, the washing plate is driven by the floating connection assembly to
climb the obstacles; meanwhile, the inner tension of the caterpillar track is increased, and therefore the center distance between the driving wheels and the driven wheels can be reduced and the caterpillar track can be tightly attached to the wall face of the ship to
climb the obstacles, and the wall face adaptability of the derusting wall-climbing robot for the ship is improved.
