KAISERLICHESIMPERIAL PATENTAMT.PATENT OFFICE. ■ Die bisher für den Transport von Blöcken gebräuchlichsten, in Verbindung mit Hebevorrichtungen angewandten Greiferzangen mit drehbaren Zangenschenkeln haben den Nachteil, daß sie bei verschiedener Länge der Blöcke ausgewechselt werden müssen oder daß jeweils eine Verstellung der Zangenschenkel erforderlich ist.■ The gripper tongs most commonly used in connection with lifting devices for the transport of blocks rotatable pliers legs have the disadvantage that they are at different lengths of Blocks have to be replaced or that an adjustment of the pliers legs is required. Vorliegende Erfindung ermöglicht, durchThe present invention enables through ίο die Anwendung horizontal geführter Greifbacken, die durch ein Kniehebelgestänge selbständig wieder auseinandergedrückt werden, Blöcke von wesentlich verschiedener Länge mit ein und derselben Greifvorrichtung zu fassen.ίο the use of horizontally guided gripper jaws, which are automatically pushed apart again by a toggle linkage, blocks of significantly different lengths to be grasped with one and the same gripping device. Die Greifvorrichtung besteht aus dem an einem Hilfsseil f hängenden Rahmen b, der zur horizontalen Führung der auf Rollen verschiebbaren Greifbacken α dient. Das mit Gewichten h belastete Gestänge g ist knie-. hebeiförmig an dem Rahmen b und den beiden Greifhacken α befestigt. Das Hubseil ist um die an dem Rahmen b und an den Greifbacken α befindlichen Rollen c flaschenzugartig geführt.The gripping device consists of the frame b hanging on an auxiliary rope f , which serves for the horizontal guidance of the gripping jaws α, which can be moved on rollers. The linkage g loaded with weights h is knee-high. attached to the frame b and the two gripping hooks α in a lever-shaped manner. The hoist rope is guided like a pulley block around the rollers c located on the frame b and on the gripping jaws α. Die Wirkungsweise ist nun die folgende:The mode of action is now as follows: Um die Greifvorrichtung je nach der LängeTo the gripping device depending on the length des Blockes e mehr oder weniger zu öffnen, wird das Hilfsseil f festgehalten und das Hubseil d nachgelassen. Die Greifbacken werden dabei durch das mit Gewichten h belastete Gestänge (g) nach außen gedrückt, ohne daß die Greifvorrichtung ihre Höhenlage zu verändern braucht. Durch gleichzeitiges Nachlassen des Hubseiles d und des Hilfsseiles f wird der Greifer in geöffnetem Zustand über den Block gebracht. Bei Anziehen des Hubseiles d bewegen sich die Greifbacken α zunächst gleichmäßig gegeneinander, bis sie gegen den Block drücken, der bei weiterem Ziehen mit der Greifvorrichtung gehoben wird. Das Hilfsseil wird hierbei in bekannter Weise durch Reibung o. dgl. mitgenommen.of the block e to open more or less, the auxiliary rope f is held and the hoist rope d slackened. The gripping jaws are pressed outwards by the rod (g) loaded with weights h , without the gripping device having to change its height position. By simultaneously slacking off the hoisting rope d and the auxiliary rope f , the gripper is brought over the block in the open state. When the hoist rope d is tightened, the gripping jaws α initially move uniformly against each other until they press against the block, which is lifted with the gripping device as the pulling continues. The auxiliary rope is entrained in a known manner by friction or the like. Patent-A ν SPRU ch:Patent-A ν SPRU ch: Eine Greifvorrichtung für Blöcke verschiedener Länge, dadurch gekennzeichnet, daß zwei Greifbacken (a) in einer geraden Linie gegeneinander geführt sind und durch das Huborgan selbst vermittels eines besonderen Flaschenzuges (c) geschlossen werden, während zum öffnen beim Nachlassen des Hubseiles das Greifergestell (b) (Rahmen o. dgl.) durch ein besonderes Hilfsseil ff), Kette o. dgl. gehalten ist und mit dem Greifbacken ein kniehebelartig wirkendes, durch Gewicht (h) o. dgl. belastetes Gestänge (g) verbunden ist, zum Zweck, ein selbsttätiges Nachaußenbewegen der Greifbacken zu bewirken.A gripping device for blocks of different lengths, characterized in that two gripping jaws (a) are guided against each other in a straight line and are closed by the lifting device itself by means of a special pulley block (c) , while the gripper frame (b) is used to open when the lifting rope is released. (Frame or the like) is held by a special auxiliary rope ff), chain or the like and a toggle-like acting rod (g) loaded by weight (h) or the like is connected to the gripping jaw for the purpose of a to cause automatic outward movement of the gripping jaws.
