The present invention relates to a power source coupling for connecting two power coupling parts (): a first power coupling part () which is mounted on a first component () so as to be longitudinally displaceable and has a first connecting plate () with one or more first power coupling elements (), and a second power coupling part () which is mounted on a second component () so as to be displaceably mounted between a first and a second position. The second power coupling part () has a second connecting plate () with one or more second power coupling elements () which are able to cooperate with the first power coupling elements () when the first power coupling part () is in the first position. A protective element () is provided on the first power coupling part () so as to be adjustable in position, and which in the first position of the power coupling part () covers the first power coupling elements () when the second power coupling part () is not attached, and in the second position of the power coupling part () is in an open position.

Power source coupling and coupler having a power source coupling

A multicoupling device for lines, especially hydraulic lines, wherein first and second coupling parts () are provided with a plug () or a collar () for coupling units () whose number corresponds to the number of connections to be produced. The coupling units () are embodied in the form of a self-locking, snap coupling with a locking collar () which can be displaced in relation to the socket (). The two coupling parts () can be brought together via an operating element () and can be pressed apart and are mutually lockable in the coupling position. The locking collars () interact with a common switch plate (). The operating element () is rotatably mounted on an axis () on the switch plate (). The switch plate () can be adjusted in relation to one of the two coupling parts () in the direction of closure or opening of the coupling units (). The two coupling parts () can be moved by the operating element (), which is mounted on the switch plate (), by engagement with curved engagement slots with pins () that protrude from the other coupling part, in relation to each other in a closing and opening position.

Multicoupling device

The invention relates to an assembly for exchangeably fastening an add-on, for example an excavator shovel (), to an excavator boom (), whereby retaining bolts () spaced apart (A) in parallel are disposed on the excavator shovel (). Said retaining bolts () can be gripped by grippers () mounted on the excavator shovel () that can be hydraulically adjusted relative to each other. Said grippers () have open insertion openings () for the retaining bolts () in directions facing away from each other. The longitudinal axis () of the hydraulic drive () for adjusting the grippers (), the center axis () of the retaining bolts () and the center axis () of the insertion openings () on the grippers () are at least approximately arranged in one plane (). One gripper () is retained in parallel to the axis of the drive () in a guide () and can be linearly displaced. The parts of the hydraulic or pneumatic drive (), namely the cylinder () and the piston () are firmly linked with the grippers () (FIG.).
