Description
WippkranLuffing crane
Es sind Wippkrane bekannt, bei denen an dem Grundausleger ein Spitzenausleger angelenkt ist und bei denen sich die Last und die Spitzenrolle auf einer Waagerechten bewegen. Bei diesen Kranen legt sich beim Einholen des Auslegers ein den Spitzenaus-' leger und das Krangerüst verbindendes Zugorgan auf ein am Spitzenausleger befindliches Kurvenstück.Luffing cranes are known in which a luffing jib is hinged to the base jib and in which the load and the top roller move on a horizontal plane. With these cranes, when the boom is hauled in, the tip out- ' casually and the crane frame connecting pulling element on a luffing jib Curve piece.
Die Erfindung besteht darin, daß auch am Krangerüst ein Kurvenstück angebracht ist, auf das sich das Zugorgan legt.The invention consists in that a curve piece is attached to the crane frame, on which the pulling organ lies.
Dadurch wird die größte Ausladung erreicht, da beide Ausleger in die Strecklage gebracht werden können. Das im Krangerüst unbeweglich angeordnete Segment sorgt dafür, daß das Zugorgan an einem genügend großen Hebelarm angreift.This achieves the greatest overhang, since both booms are in the extended position can be brought. The segment, which is immovably arranged in the crane frame, ensures that the pulling element is sufficiently attached to one another attacks large lever arm.
Ein Ausführungsbeispiel der Erfindung ist so in. der Zeichnung dargestellt.An embodiment of the invention is shown in. The drawing.
Um den im Krangerüst festen Drehpunkt a ist der Grundausleger b drehbar angeordnet. An seinem freien Ende befindet sich das zum Ausgleich des Eigengewichts der Auslegers5 teile dienende Gegengewicht c. Am vorderen Gelenkpunkt ei ist der Spitzenausleger e drehbar angeordnet, der die Spitzenrolle / trägt, über die das'Lastseil §· läuft. Weitere Lenkrollen h und i für das Lastseil befinden sich am Gelenkpunkt d und im Drehpunkt α. Mit dem Spitzenausleger e ist ein Segment k fest verbunden, das. nach einem Kreise gekrümmt ist, dessen Mittelpunkt in d liegt. Das Zugorgan I hat seine Festpunkte bei m und n. The base jib b is rotatably arranged around the pivot point a fixed in the crane frame. At its free end is the counterweight c , which is used to compensate for the weight of the boom5 parts. The jib boom e , which carries the jib pulley / over which the load rope § · runs, is rotatably arranged at the front articulation point ei. Further swivel castors h and i for the load rope are located at the pivot point d and at the pivot point α. A segment k is firmly connected to the fly jib e , which is curved according to a circle whose center lies in d. The pulling element I has its fixed points at m and n.
Im Krangerüst fest ist das Segment 0 angeordnet. Segment 0 is fixed in the crane frame.
Die Krümmungen der Segmente k und 0 sind derart zueinander bestimmt, daß beide Ausleger in die Strecklage gebracht werden können. Beim Einwippen des Kranes legt sich das Zugelement auf das Segment k auf und wälzt sich vom festen Segment 0 ab.The curvatures of the segments k and 0 are determined in relation to one another in such a way that both arms can be brought into the extended position. When the crane is luffed in, the tension element rests on segment k and rolls off fixed segment 0 .
Die Erfindung ist an das in der Zeichnung dargestellte Ausführungsbeispiel nicht gebunden, insbesondere kommt es nicht darauf an, ob die Segmente und Zugelemente in einfacher oder mehrfacher Anordnung angewendet werden, ob diese Zugelemente als Seile oder als Ketten, Gliederketten u. dgl. ausgeführt werden. Auch die Art des Antriebes des hinteren GelenkauslegeYs ist beliebig.The invention is not bound to the embodiment shown in the drawing, in particular, it does not depend on whether the segments and tension elements in simple or multiple arrangements can be used, whether these tension elements are designed as ropes or as chains, link chains and the like will. The type of drive for the rear articulated extension is also optional.
Die Zeichnung zeigt die ausgestreckte Lage des Wippauslegers in voll ausgezogenen Linien, die eingezogene Lage in gestrichelten Linien.The drawing shows the extended position of the luffing jib in full lines, the indented position in dashed lines.
