"Vorliegende Erfindung bezieht sich auf Krane sowie Hebezeuge aller Art und hat den Zweck, das in bekannter Weise an teleskopartig ineinander verschiebbaren Rohren hängende Greifwerkzeug in allen Höhenlagen durch eine geeignete Führung gegen seitliche Schwankungen zu sichern und gleichzeitig auch einen möglichst großen Hub zu erzielen. Erreicht wird der genannte Zweck dadurch, ίο daß in einem festen Rahmen bewegliche Querstücke angeordnet sind, die durch, Ansätze an den ausziehbaren Rohren mitgenommen werden."The present invention relates to Cranes and hoists of all kinds and has the purpose of being telescopic in a known manner Slidable pipes hanging gripping tool in all heights by a suitable guide against the side To secure fluctuations and at the same time to achieve the largest possible stroke. The stated purpose is achieved in that ίο that movable cross pieces in a fixed frame are arranged, which are taken by, lugs on the extendable tubes will.
Auf den beiliegenden Zeichnungen ist der Erfindungsgedanke in einem Ausführungsbeispiele zur Veranschaulichung gebracht, und zwar zeigt Fig. 1 die Vorrichtung in einer Seitenansicht in gehobener Lage; Fig. 2 ist der zugehörige Grundriß, und nach der Seitenao ansicht Fig. 3 ist die Vorrichtung gesenkt worden.The concept of the invention is illustrated in an exemplary embodiment in the accompanying drawings, and FIG 1 shows the device in a side view in the raised position; Fig. 2 is the associated plan, and after the Seitenao view Fig. 3, the device is lowered been.
Als Greif werkzeug ist eine Zange angenommen. A pair of pliers is assumed as a gripping tool.
• . In einem festen, von der Katze niederes gehenden Rahmen α ist ein Querstück b beweglich angeordnet. Mit diesem Querstück ist ein Rohr c derart verbunden, daß es sich in vertikaler Richtung nur gemeinsam mit dem Querstück b bewegen kann, während das Rohr unabhängig von dem in vertikaler Richtung geführten Querstück b drehbar bleibt. An seinem unteren Ende trägt das Rohre einen Bund, auf dem das Querstück rf'ruht.•. A cross piece b is movably arranged in a fixed frame α that goes down from the trolley. A tube c is connected to this crosspiece in such a way that it can only move in the vertical direction together with the crosspiece b , while the tube remains rotatable independently of the crosspiece b guided in the vertical direction. At its lower end, the tube has a collar on which the crosspiece rests.
Letzteres sitzt lose auf dem Rohr c, ist aber ebenso wie das Querstück b in dem festen Rahmen α geführt und an der Drehbewegung gehindert. In das Rohr c ist noch ein zweites Rohr e eingeschoben, welches unten die Zange o. dgl. trägt und oben ah dem Lastseil hängt.The latter sits loosely on the tube c, but like the crosspiece b is guided in the fixed frame α and prevented from rotating. A second tube e is inserted into the tube c, which carries the pliers or the like at the bottom and hangs the load rope at the top.
Wird nun die Zange gesenkt, so gleiten die beiden Querstücke b und d in dem festen Rahmen α abwärts, bis das Querstück d am Ende dieses Rahmens durch ein Widerlager festgehalten wird. Nunmehr gleitet das Rohr c durch das Querstück d, bis dasjenige b auf ersterem aufliegt. Soll noch weiter gesenkt werden, so tritt das Rohr e aus dem Rohre c hervor (Fig. 3). Nach Erfassen des betreffenden Gegenstandes, beispielsweise eines Blockes, wird durch das Lastseil das innere Rohr e gehoben, bis es mit einem dafür vorgesehenen Ansatz gegen den unteren Bund des Rohres c stößt. Sodann werden beide Rohre mit dem Querstück b so lange gehoben, bis auch das Querstück d durch einen unten an dem Rohr C befindlichen Bund mitgenommen wird.If the pliers are now lowered, the two cross pieces b and d slide downward in the fixed frame α until the cross piece d is held at the end of this frame by an abutment. Now the tube c slides through the crosspiece d until the one b rests on the former. If it is to be lowered even further, the tube e emerges from the tube c (FIG. 3). After the object in question, for example a block, has been grasped, the inner tube e is lifted by the load rope until it hits the lower collar of the tube c with a shoulder provided for this purpose. Then both tubes with the crosspiece b are lifted until the crosspiece d is carried along by a collar located at the bottom of the tube C.
Die Zange ist also in jeder Höhenlage gut geführt und gegen seitliche Schwankungen gesichert. Infolge dieser ver'schieblichen Führungen wird auch ein möglichst großer Hub erzielt.The pliers are therefore well guided at any altitude and against lateral fluctuations secured. As a result of these displaceable guides, the greatest possible stroke is also achieved achieved.
