Description
Die Erfindung betrifft einen Kran mit Wippausleger, in welchem der Ausgleich der Aufwärtsbewegung, die die Seilrolle an der Spitze des Auslegers macht, dadurch bewirkt ward, daß das Seil, das von der Seilrolle nach der Seiltrommel läuft, auf seinem Weg über verschiedene Leitrollen geleitet wird, deren von der Drehung des Auslegers abhängige Bewegungen die Länge des Seiles in derThe invention relates to a crane with a luffing jib, in which the compensation of This causes upward movement that the pulley makes at the tip of the boom was that the rope, which runs from the pulley to the rope drum, over on its way different guide rollers is guided, whose depending on the rotation of the boom Movements the length of the rope in the
Jo Weise verändern, daß der Lasthaken sich möglichst auf einer geraden Linie bewegt.Jo change the way that the load hook moves in a straight line as far as possible.
Bei einer bekannten Ausführungsform wird das von der Hubtrommel kommende Seil zunächst über eine im Drehpunkt des Auslegers befindliche Rolle geführt, sodann läuft es über eine auf einer Kurvenbahn des Auslegers verschiebbare Rolle und gelangt von dort zur Rolle an der Auslegerspitze. Die Bewegung der auf der Kurvenbahn verschiebbaren Rolle wird beim Wippen dadurch gesteuert, daß diese Rolle an einem am Krangerüst angreifenden Lenker befestigt ist. Bei dieser Ausführung ergibt sich zwar der Vorteil einer geringen Zahl von Rollen, in der Praxis zeigt sich aber, daß die Unterbringung der Kurvenbahn infolge ihrer Länge im Auslegerschwanz erhebliche Schwierigkeiten verursacht, abgesehen davon, daß die Herstellung der Kurvenbahn umständlicher ist. Ungünstig wirkt sich bei dieser Ausbildung der Ausgleichseinrichtung auch die in der Richtung wechselnde Biegung des Seiles auf den Rollen aus.In a known embodiment, the coming from the lifting drum Rope first passed over a roller located in the pivot point of the boom, then it runs over a roller that can be moved on a curved path of the boom and arrives from there to the roll at the boom tip. The movement of the slidable on the cam track When rocking, the role is controlled by the fact that this role is attached to a link acting on the crane frame. In this embodiment, there is the advantage of a small number of roles in which In practice, however, it has been shown that the accommodation of the curved path due to its length in the cantilever tail causes considerable difficulties, apart from the fact that the production of the cam track is more complicated. Unfavorable in this design of the compensating device also affects the direction alternating bending of the rope on the pulleys.
Es ist ferner eine Anordnung bekannt, bei der am hinteren Teil des Krangerüstes zwei Rollen auf gemeinsamer Achse befestigt und zwei weitere Rollen in einer Geradführung im Auslegerschwanz verschiebbar sind. Das von der Hubtrommel kommende Seil läuft hierbei zunächst um die eine feste Rolle, dann zu einer beweglichen, ferner zu der zweiten festen zurück und schließlich über die zweite bewegliche Rolle zur Spitze des Auslegers. Als Mittel zur Steuerung der beweglichen Rolle ist eine Kurvenbahn vorgesehen, so daß die Bewegung der Rollen im Auslegerschwanz beim Wippen durch zwei Paar Führungen bewirkt wird; es müssen also auf der Rollen-, achse außer den zwei Rollen noch vier Führungselemente befestigt sein. Es ergibt sich mithin eine konstruktiv nicht leicht zu lösende Aufgabe, besonders wenn der Kran mit einem Zweiseilgreifer arbeiten soll, wobei die Zahl der Rollen auf der beweglichen Achse noch erhöht wird.There is also an arrangement known in which two at the rear of the crane frame Rollers attached to a common axis and two additional rollers in a straight line are slidable in the boom tail. The rope coming from the hoist drum runs here first around a fixed role, then to a movable one, then to the second fixed back and finally via the second movable roller to the top of the boom. A cam track is provided as a means for controlling the movable roller, so that the movement of the rollers in the boom tail when rocking through two pairs of guides is effected; So there must be four guide elements on the roller axis in addition to the two rollers be attached. There is therefore a structurally not easy to solve task, especially if the crane with a Two-rope grab is supposed to work, with the number of rollers on the moving axis still is increased.
Bei dem Kran gemäß der Erfindung ist im hinteren Teil des als doppelarmiger Hebel ausgebildeten Auslegers eine Geradführung für nur eine verschiebbare, mittels eines oben an der Kransäule des Krangerüstes angreifen- 6qThe crane according to the invention is in the rear part of the double-armed lever trained boom a linear guide for only one displaceable, by means of a top Attack on the crane column of the crane frame- 6q
