Abstract

Abstract The aircraft washing equipment comprises a sub-arm (15) that rotates at the tip of an ascendable and descendable arm (9) by means of a shaft (7) with a base perpendicular to the arm, and is movably controlled by a drive mechanism; a brush oscillating frame (32) rotated by a drive mechanism at the tip of the sub-arm, and which base rotates by means of a shaft (33′) perpendicular to the longitudinal direction of the sub-arm and a shaft at the tip of the arm; a brush swivelling frame (33) that is swivelled by a drive mechanism centering around the axis of the longitudinal direction of the brush oscillating frame; a brush arm (35, 36) 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 (33) 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 (35, 36) mutually coupled with a universal joint, with their bases on the brush swivelling frame and the brush arm, and protruding perpendiculary to the swivelling plane of the brush swivelling frame; and a drive mechanism (34) to drive the rotating brush around the center axis.

Claims Analysis

Total Claims: 3

Claim 1

Independent Claim 209 words

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 control led 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.

Claim 2

Dependent Claim 209 words

Claim 3

Dependent Claim 56 words

Aircraft washing equipment with each mechanism as claimed in claim 1, mounted on a truck with runnable and steerable wheels, and transversal wheels which are disposed perpendicularly to the longitudinal axis of the truck, and protrude downward to release the steerable and rotating wheels from contact with the ground in order to move the truck transversally.
