Abstract
Description
Der etwa um 20% gegenüber dem Gegengewicht 12 schwerere Greifer 8 wird beim Anheben durch das sich gleichzeitig absenkende Gegengewicht 12 im Gewicht entlastet, wobei umgekehrt beim Absenken des Greifers 8 nur geringe Bremskräfte am Hubwerk 6 wirken. Beim Aufsetzen des Greifers 8 auf dem Seeboden sind die Hubwerksbremsen geschlossen, so daß der Greifer mit seinem vollen Gewicht ohne Entlastung graben kann. The gripper 8, which is roughly 20% heavier than the counterweight 12 becomes when lifting through the itself counterweight lowering at the same time 12 relieved in weight, while conversely when lowering the gripper 8 only slight Braking forces act on hoist 6. When placing the gripper 8 on the seabed the hoist brakes are closed, so that the grab with its full weight can dig without relief.
In dem gezeigten Ausführungsbeispiel ist auf der Halgewinde 7 eine zusätzliche Wickelfläche für das Seil 10 vorgesehen. Man kann das Seil 10 zur Haltewinde 7 auch so anordnen, daß sich dieses Seil 10 beim Absenken des Greifers 8 auf die freiwerdende Haltewinde 7 direkt aufwickelt. In the embodiment shown, on the half-thread 7 is a additional winding surface for the rope 10 is provided. You can use the rope 10 to hold the winch 7 also arrange so that this rope 10 when lowering the gripper 8 on the released retaining thread 7 winds directly.
Durch diese Ausbildung und Anordnung des Gegengcwichts 12 läßt sich auch der Antrieb 15 für die Laufkalze 5 vereinfachen, wobei dieser Antrieb am gegenüberliegenden Ende des Querträgers 3 zur Umlenkrolle 11 angeordnet ist. Der Antrieb erfolgt über ein Seil 16, wobei bei einer Bewegung in Richtung zum Katzfahrantrieb 15 eine Zugkraft ausgeübt wird, während in der entgegengesetzten Richtung die Laufkatze 5 von dem Gegengewicht gezogen wird und am Antrieb 15 eine Bremswirkung erzeugt werden muß. This design and arrangement of the counterweight 12 can also simplify the drive 15 for the roller 5, this drive on the opposite The end of the cross member 3 is arranged for the deflection roller 11. The drive takes place via a rope 16, with a pulling force when moving in the direction of the trolley drive 15 is exercised while in the opposite direction the trolley 5 of the Counterweight is pulled and a braking effect must be generated on drive 15.
Bei der in den Fig.3 und 4 dargestellten Ausführungsform wird der Greifer 8 direkt mit dem Gegengewicht 12 entlastet, indem das Seil 10 über eine zusätzliche Umlenkrolle 17 auf der Laufkatze 5 am Greifer 8 befestigt ist. Bei leicht baggerfähigem Material ist diese Ausführungsform ohne weiteres anwendbar. In the embodiment shown in Figures 3 and 4, the Gripper 8 relieved directly with the counterweight 12 by the rope 10 over a additional pulley 17 is attached to the trolley 5 on the gripper 8. With easy This embodiment is readily applicable to excavable material.
Bei der Ausführungsform nach den F i g. 5 und 6 ist die Laufkatze 5 mit einem eigenen Fahrantrieb versehen, wobei das Seil 10 über zwei zusätzliche Umlenkrollen 18,19, jeweils am Ende des Querträgers 3 umgelenkt und an der anderen Seite der Laufkatze 5 befestigt ist. In the embodiment according to FIGS. 5 and 6 is the trolley 5 provided with its own drive, the rope 10 has two additional Deflection rollers 18, 19, each deflected at the end of the cross member 3 and at the other Side of the trolley 5 is attached.
Die in den F i g. 7 und 8 dargestellte Ausführungsform ist für einen Vierseilgreiferbetrieb geeignet, wobei auf der Laufkatze 5 neben der Haltewinde 7 noch eine Schließwinde 20 angeordnet ist. Das Seil 10 für das Gegengewicht 12 ist hierbei an der Haltewinde 7 angeordnet. The in the F i g. 7 and 8 illustrated embodiment is for a Four-rope gripper operation suitable, being on the trolley 5 in addition to the retaining winch 7 a closing winch 20 is also arranged. The rope 10 for the counterweight 12 is here arranged on the retaining thread 7.
Schließlich zeigen die Fig. 9 und 10 eine Ausführungsform, bei der für einen solchen Hydraulikgreiferbetrieb an einer Vierseilwinde das Gegengewicht 12 geteilt ist und das jeweilige Teilgewicht einmal an der Haltewinde 7 bzw. an der Schließwinde 20 angeordnet ist. Es kann hierbei der vorhandene Fahrantrieb für die Laufkatze 5 beibehalten werden. Finally, FIGS. 9 and 10 show an embodiment in which the counterweight for such hydraulic grab operation on a four-rope winch 12 is divided and the respective part weight once on the retaining thread 7 or on the closing winch 20 is arranged. It can use the existing drive for the trolley 5 can be maintained.
