System and coupling device for automatically coupling a mobile machine, in particular a container-stacking crane, to a mobile consumer supply system, and a coupling therefor

摘要

A system for automatically docking a container stacker crane, in particular a RTG, to a movable supply, having a docking device with a transverse advancer unit and an extendable extension arm of which an end portion can be advanced transversely to the movable supply and connects thereto. An energy guiding chain with an entrainment member serves as a movable supply. A mechanical coupling is proposed with a coupling piece on the end portion and a coupling counterpart on the entrainment member. The entrainment member floatingly supports the coupling counterpart with transverse play. A plug connector on said end portion cooperates with a socket on the entrainment member. The mechanical coupling has a coupling piece configured as a funnel and a cooperating coupling counterpart configured as coupling head. The coupling head includes at least one extension, which cooperates with the funnel and/or a locking bolt for securing perpendicular to the longitudinal direction. The locking bolt cooperates with the extension for securing in the longitudinal direction, and for securing the coupling head in a fixed position.
