Abstract
The present invention provides an aircraft washing equipment, characterized in that it comprises a sub-arm that rotates at the tip of an ascendable and descendable arm by means of a shaft with a base perpendicular to the arm, and is movably controlled by a drive mechanism; a brush oscillating frame rotated by a drive mechanism at the tip of the sub-arm, and which base rotates by means of a shaft perpendicular to the longitudinal direction of the sub-arm and a shaft at the tip of the arm; a brush swivelling frame that is swivelled by a drive mechanism centering around the axis of the longitudinal direction of the brush oscillating frame; a brush arm attached to a hinge on both sides of the brush swivelling frame, disposed bendably in a plane which is parallel to the swivelling plane of the brush swivelling frame, and is bent by a drive mechanism; a center shaft of a rotating brush attached on brackets parallel to the brush swivelling frame and the brush arm, mutually coupled with a universal joint, with their bases on the brush swivelling frame and the brush arm, and protruding perpendicularly to the swivelling plane of the brush swivelling frame; and a drive mechanism to drive the rotating brush around the center axis.
