Abstract
Description
schnitt etwa die Form einer Viertelkreisfläche auf. Durch den dem ideeilen Kreismittelpunkt entsprechenden Querschnittsbereich erstreckt sich eine Lagerachse 16, rohrförmig ausgebildet Diese bildet ,zusammen mit den Lagerschalen 13 das Stützlager für die Greiforgane. In diesen Bereichen sind beide Greilorgane durch eine Lasche 17 miteinander verbundea An einem Winkel zwischen Kreisbogen und Radius des Querschnitts ist eine Verriegelungsstelle 18 für den Schwenkhebel 9 und ein Anschlag 19 angebrachtcut about the shape of a quarter circle. By the corresponding to the ideal circle center Cross-sectional area extends a bearing axis 16, tubular shape. This forms, together with the bearing shells 13, the support bearing for the gripping organs. In these areas, both gripping organs are through one Tab 17 connected to one another at an angle between the circular arc and the radius of the cross-section a locking point 18 for the pivot lever 9 and a stop 19 attached
Die Verbindung zwischen den Greiforganen und der Träger- bzw. Betätigungseinrichtung ist bei einem Wechsel der Greiforgane auf einfache Weise und im Bereich des aus den Lagerschalen 13 und den Lagerachsen 16 bestehenden Stützlagers selbsttätig zu lösen bzw. zu schließen. F i g. 1 zeigt die Ausgangsstellung zur Aufnahme von Greiforganen durch die übrigen Einrichtungen. Die Greiforgane 3 befinden sich in einer Offenstellung, am Boden mit jeweils einer Kante abgestützt Zusätzlich ist im Bereich der Lasche 17 eine in Fig. 1 gestrichelt angedeutete Unterstützung 20 vorgesehen. Diese kann aus Holz, Stein oder Sand bestehen. Die Zylinder-Kolbeneinheiten befinden sich in ihrer zurückgezogensten Stellung. Dadurch nehmen die Schwenkhebel 9 eine im wesentlichen vertikale Haltung ein und die Lagerschalen 13 sind mit ihrer Öffnung nach unten gerichtet. Wird nun mittels der Arbeitsmaschine, beispielsweise des Baggers, die Trägereinrichtung 1 über die Greiforgane gebracht, mittels des Drehwerks 6 in die richtige Stellung geschwenkt und anschließend abgesenkt, so setzen die Lagerschalen 13 auf die Lagerachsen 16 der Greiforgane auf. Werden nunmehr die Zylinder-Kolbeneinheiten 8 betätigt bewegen sich die Schwenkhebel 9 nach außen, bis sie am Anschlag 19 anliegen. Diese Bewegung erfolgt im wesentlichen synchron. The connection between the gripping members and the carrier or actuating device is at one Change of the gripping members in a simple manner and in the area of the bearing shells 13 and the bearing axles 16 existing support bearing to solve or close automatically. F i g. 1 shows the starting position for recording of grasping organs by the other facilities. The gripping organs 3 are in an open position, supported on the ground with one edge each. In addition, one in FIG. 1 is dashed in the area of the tab 17 indicated support 20 provided. This can consist of wood, stone or sand. the Cylinder-piston units are in their most retracted position. This will take the pivot lever 9 a substantially vertical posture and the bearing shells 13 are directed with their opening downwards. If now by means of the machine, for example the excavator, the carrier device 1 via the Brought gripping organs, pivoted by means of the rotating mechanism 6 into the correct position and then lowered, so put the bearing shells 13 on the bearing axles 16 of the gripping organs. Now the cylinder-piston units When actuated 8, the pivot levers 9 move outward until they rest against the stop 19. This movement is essentially synchronous.
In F i g. 2 sind zur Verdeutlichung der Vorgänge links und rechts seitlich etwas unterschiedliche Stellungen dargestellt: in der rechten Zeichnungshälfte hat der Schwenkhebel 9 mit seinem lagerschalenförmigen Ende die Verriegelungsstelle 18 noch nicht erreicht Der Schwenkhebel 9 auf der linken Seite der F i g. 2 liegt bereits am Anschlag 19 an und ist mittels eines Bolzens 21 bereits an der Verriegelungsstellung 18 des Greiforgans 3 befestigt. Außer dem Anbringen dieser beiden Bolzen 21 ist nichts zur Verbindung der Greiforgane mit der Träger- bzw. Betätigungseinrichtung erforderlich.In Fig. 2 are slightly different positions to the left and right to clarify the processes shown: in the right half of the drawing has the pivot lever 9 with its bearing shell-shaped end the locking point 18 has not yet been reached. The pivot lever 9 on the left-hand side of FIG. 2 lies already on the stop 19 and is already in the locking position 18 of the gripping member by means of a bolt 21 3 attached. Except for the attachment of these two bolts 21 is nothing to connect the gripping members with the carrier or actuating device required.
F i g. 3 zeigt die Greifervorrichtung in Gebrauchsstellung, wobei durch Ausfahren der Zylinder-Kolbeneinheiten 8 die Greiforgane 3 geschlossen sind. Die Anordnung der drei Gelenkstellen: Verriegelungsstelle 18, Lagerbolzen 12 und Lagerachse 16 zueinander bildet einen stumpfen Winkel, der zusammen mit dem Querschnitt der Lagerschale 13 und dem Gestänge 15 gewährleistet, daß die Lagerschale stets die Lagerachse des Greiforganes unterstützt und die auftretenden Kräfte an den Schwenkhebel 9 weiterleitet.F i g. 3 shows the gripper device in the position of use, wherein the gripping members 3 are closed by extending the cylinder-piston units 8. The order of the three hinge points: locking point 18, bearing pin 12 and bearing axis 16 to each other forms one obtuse angle, which ensures together with the cross section of the bearing shell 13 and the linkage 15, that the bearing shell always supports the bearing axis of the gripping member and the forces acting on the Swivel lever 9 forwards.
Das Lösen der Greiforgane von der 1 rägereinrichtung erfolgt in umgekehrter Weise ebenso rasch und einfach: die geöffneten Greiforgane sind auf dem Boden eo abzustutzen, die Bolzen 21 an den Vernegelungsstellen 18 werden entfernt und nach einer entsprechenden Schwenkbewegung der Schwenkhebel bzw. Lagerschalen können Träger- und Betätigungseinrichtung mittels der Arbeitsmaschine von dem Greiforgan abgehoben werden.The release of the gripping organs from the 1 carrier device takes place in the opposite way just as quickly and easily: the opened grasping organs are on the floor eo cut off the bolts 21 at the locking points 18 are removed and, after a corresponding pivoting movement, the pivot lever or bearing shells the carrier and actuating device can be lifted off the gripping member by means of the working machine will.
Bei der beschriebenen üreifervorrichtung können Greiforgane beliebiger Formen verwendet werden.In the case of the gripping device described, gripping members of any desired shape can be used.
Ebenso können Einzelheiten der Trägereinrichtung und der Betätigungseinrichtung variieren, soweit die Verbindungsmöglichkeit mit den Greiforganen bestehen bleibtLikewise, details of the carrier device and the actuating device can vary, as far as the connection possibility persists with the grasping organs
Es können auch mehr als zwei Greiforgane sternförmig um den Träger angeordnet sein, jeweils mit Betätigungszylindern, Schwenkhebeln und Lagerschalen. Die Lagerschalen können schwenkbar mit den Schwenkhebeln verbunden sein und durch die Zylinder-Kolbeneinheit direkt aufsetzbar sein. Das Bewegen und Verriegeln der Schwenkhebel erfolgt dann von HandIt is also possible for more than two gripping organs to be arranged in a star shape around the carrier, each with actuating cylinders, Swivel levers and bearing shells. The bearing shells can be pivoted with the pivot levers be connected and be placed directly by the cylinder-piston unit. Moving and locking the swivel lever is then done by hand
