Description

Die Erfindung betrifft eine Hakenflasche für einen Kran, vorzugsweise für einen Fahrzeugkran, nach dem Oberbegriff des Anspruchs 1.The invention relates to a hook block for a crane, preferably for a vehicle crane, according to the preamble of claim 1.

Bei einer Hakenflasche handelt es sich um die Verbindung zwischen dem Hubseils eines Krans und der Last. Die Hakenflasche weist ein Unterteil auf, an welchem ein entsprechend ausgeformter Haken dreh- und kippbar befestigt ist. In dem mit diesem Unterteil verbundenen Oberteil sind Seilscheiben, die hier im folgenden als Rollen bezeichnet werden, auf einer Welle angeordnet. Über die Rollen wird nach dem Flaschenzugprinzip das Hubseil eingeschert.A hook block is the connection between the hoisting rope of a crane and the load. The hook block has a lower part, on which a correspondingly shaped hook is attached rotatable and tiltable. In the upper part connected to this lower part are pulleys, which are hereinafter referred to as rollers, arranged on a shaft. About the roles of the hoist rope is reeved according to the pulley principle.

Je nach Aufgabe sind nun Hakenflaschen mit unterschiedlichen Rollensätzen einzusetzen. Hierzu muss eine Reihe unterschiedlicher Hakenflaschen gefertigt und vorrätig gehalten werden.Depending on the task hook hooks with different roller sets are now to be used. For this purpose, a number of different hook bottles must be made and kept in stock.

US 2004/0084917 offenbart ein Unterflaschensystem für eine vorgegebene Maximallast, zur Bildung von unterschiedlich tragfähigen Unterflaschen für einen Kran. US 2004/0084917 discloses a bottom tank system for a given maximum load, for forming differently loadable bottom bottles for a crane.

Aufgabe der Erfindung ist es, den Fertigungsaufwand und die Lagerhaltung für Hakenflaschen zu minimieren.The object of the invention is to minimize the production cost and storage for hook bottles.

Erfindungsgemäß wird diese Aufgabe durch Anspruch 1 gelöst, wobei bei einer gattungsgemäßen Hakenflasche für einen Kran mit einem Unterteil, an dem der Haken dreh- und kippbar befestigt ist, und einem Oberteil, in dem die Rollen gelagert sind, über die mindestens ein Hubseil einscherbar ist, die Rollen in mehren modulartig miteinander verbindbaren Rollensätzen zusammengefaßt sind. Erfindungsgemäß können also verschiedene Flaschen im Baukastenprinzip aus den einzelnen Modulen aufgebaut werden. Dies erhöht die Flexibilität im Einsatz der mit geführten Hakenflasche, da die einzelnen Module der Hakenflasche für unterschiedliche Einsätze unterschiedlich miteinander kombinierbar sind.According to the invention this object is achieved by claim 1, wherein in a generic hook block for a crane with a lower part on which the hook is rotatably and tiltably attached, and an upper part in which the rollers are mounted, on the at least one hoist rope is einscherbar , The roles are summarized in several modularly connectable sets of rollers. According to the invention, therefore, different bottles can be constructed on a modular basis from the individual modules. This increases the flexibility in the use of guided hook block, since the individual modules of the hook block for different uses can be combined differently.

Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen.Preferred embodiments of the invention will become apparent from the subsequent claims to the main claim.

Demnach sind die Rollen über eine Hakentraverse mit dem Haken verbunden.Accordingly, the rollers are connected via a hook beam with the hook.

Ein Paar mit jeweils zwei Rollensätzen unterschiedlicher Rollenzahl kann hier miteinander verbunden werden. Die Rollensätze sind jeweils miteinander verbolzbar. Hierdurch lassen sich die verschiedenen Rollensatzkonstellationen sehr einfach zusammenstellen.A pair of two sets of rollers with different numbers of rollers can be connected here. The roller sets are each bolted together. This makes it easy to put together the different roller set constellations.

Bei der Ausbildung der Hakenflasche mit einem Paar mit jeweils zwei Rollensätzen unterschiedlicher Rollenzahl können vorteilhaft zwei Hubseile von zwei Winden einscherbar sein, wobei die Winden im Parallelbetrieb fahrbar sind und wobei das unterschiedliche Laufverhalten beider Winden, das nicht zu vermeiden ist, über die Hakentraverse ausgleichbar ist. Hierzu sind die einzelnen jeweils miteinander zusammengefaßten Rollensätze pendelnd über die Hakentraverse miteinander verbunden.In the formation of the hook bottle with a pair of two sets of rollers different numbers of rollers can be advantageous einscherbar two hoists of two winches, the winches are movable in parallel operation and wherein the different running behavior of both winds, which can not be avoided, can be compensated via the hook crossmember. For this purpose, the individual roller sets, which are in each case combined with one another, are connected in a pendulum manner via the hook traverse.

In beispielhaften Ausgestaltung kann nur ein Teil der Rollensätze in einer anderen Kombination miteinander verbunden sein. Somit lässt sich je nach Einsatz eine Vielzahl von Hakenflaschenkonstellationen zusammenstellen. Die jeweiligen Rollensätze sind hierzu miteinander kombinierbar. Je nach Breite und Ausgestaltung der Rollensätze sind allerdings unterschiedliche Haken und Hakentraversen zu verwenden.In an exemplary embodiment, only a part of the roller sets can be connected to one another in a different combination. Thus, depending on the application, a large number of hook bottle constellations can be put together. The respective roller sets can be combined with each other. Depending on the width and design of the roller sets, however, different hooks and hooks are to be used.

In der Figur 1 ist eine Hakenflasche 10 in der erfindungsgemäßen Modulaufbauweise dargestellt. Hier ist ein Haken 12 um ein Schwenklager 14 schwenkbar in einer Hakentraverse 16 gelagert. Die Hakentraverse 16 bildet zusammen mit dem schwenkbar gelagerten Haken 12 das Unterteil der Hakenflasche 10. Das Oberteil der Hakenflasche 10 wird durch mehrere modulartig miteinander verbindbare Rollensätze 18, 20, 22 und 24 gebildet. Diese Rollensätze können modulartig miteinander verbunden werden, wobei die Verbindung hier üblicherweise über eine Verbolzung erfolgt. In dem hier dargestellten Ausführungsbeispiel sind die Rollensätze 18 und 20 bzw. 22 und 24 mit einer gleichen Anzahl von Rollen versehen. So weisen die Rollensätze 18 und 20 jeweils sieben Rollen 26 auf, während die Rollensätze 22 und 24 jeweils fünf Rollen 26 aufweisen. Wie in der Figur 1 dargestellt, sind die Rollensätze 18 und 22 einerseits und 20 und 24 andererseits miteinander verbolzt, wobei diese jeweils mit der Hakentraverse 16 derart verbolzt sind, dass eine Pendelbewegung zugelassen wird. Auf der der Hakentraverse 16 gegenüberliegenden Seite sind die beiden jeweils zusammengefaßten Rollensätze 18 und 22 bzw. 20 und 24 über einen Bügel 28 miteinander verbunden.In the FIG. 1 a hook bottle 10 is shown in the modular construction according to the invention. Here, a hook 12 is pivotally mounted about a pivot bearing 14 in a Hakentraverse 16. The hook traverse 16 forms together with the pivotally mounted hook 12, the lower part of the hook bottle 10. The upper part of the hook bottle 10 is formed by a plurality of modularly interconnectable roller sets 18, 20, 22 and 24. These roller sets can be modularly connected to each other, wherein the connection is usually done here via a bolting. In the embodiment shown here, the roller sets 18 and 20 or 22 and 24 are provided with an equal number of rollers. Thus, the roller sets 18 and 20 each have seven rollers 26, while the roller sets 22 and 24 each have five rollers 26. Like in the FIG. 1 are shown, the roller sets 18 and 22 on the one hand and 20 and 24 on the other each other bolted, which are each bolted to the hook beam 16 such that a pendulum motion is allowed. On the hook traverse 16 opposite side of the two combined sets of rollers 18 and 22 or 20 and 24 via a bracket 28 are interconnected.

Die unterschiedliche Anzahl von Rollen 26 in den Rollensätzen 18, 20, 22 und 24 ermöglicht es grundsätzlich, verschiedene Hakenflaschen 10 darzustellen, In der Ausführung gemäß Figur 1 ist die Hakenflasche 10 so aufgebaut, dass zwei Hubseile von zwei Winden eingeschert werden können. Dies ist erforderlich, da eine einzige Hubseillänge nicht ausreichend wäre, um die Hakenflasche 10 auf den Boden abzusenken. Das bedeutet, dass beide Winden (hier nicht dargestellt) in Parallelbetrieb gefahren sind. Über die Hakentraverse 16 wird das unterschiedliche Laufverhalten der beiden Winden ausgeglichen.The different number of rollers 26 in the roller sets 18, 20, 22 and 24 makes it fundamentally possible to represent different hook bottles 10, in the embodiment according to FIG. 1 the hook block 10 is constructed so that two hoisting ropes can be reeved by two winches. This is necessary because a single hoist rope length would not be sufficient to lower the hook block 10 to the ground. This means that both winches (not shown here) are in parallel operation. About the hook beam 16, the different running behavior of the two winds is compensated.

In Figur 2 ist eine beispielhafte modulartige Zusammenstellung der Hakenflasche 10 gezeigt. Hier sind die Rollensätze 18 und 20 derart miteinander gekoppelt, dass sie wie ein einziger Rollensatz wirken. Hierzu sind die Rollensätze 18 und 20 starr miteinander gekoppelt. In üblicher Weise sitzt unter diesem aus den Rollensätzen 18 und 20 gebildeten Oberteil der Hakenflasche 10 wieder das Unterteil der Hakenflasche 10 bestehend aus der Hakentraverse 16 und dem schwenkbaren Haken 12. Diese Ausführung dient dazu, nur mit einer Winde einzuscheren. Die Hubseile 30 sind hier einseitig in Form eines sogenannten Schrägzugs mit einem Winkel von > 4° dargestellt.In FIG. 2 an exemplary modular assembly of the hook block 10 is shown. Here, the roller sets 18 and 20 are coupled together so that they act as a single set of rollers. For this purpose, the roller sets 18 and 20 are rigidly coupled together. In the usual way sits under this formed from the sets of rollers 18 and 20 upper part of the hook bottle 10 again the lower part of the hook block 10 consisting of the hook beam 16 and the pivoting hook 12. This design serves to scissor only with a winch. The hoisting ropes 30 are shown here on one side in the form of a so-called diagonal pull with an angle of> 4 °.

Ein weiteres Beispiel, das eine Hakenflasche 10 zeigt, die aus den Rollensatzmodulen 18 und 20 zusammengesetzt ist, ergibt sich aus Figur 3. Dort sind die Rollensatzmodule pendelnd miteinander verbunden, so dass wiederum ein Seillängenausgleich erfolgen kann, wenn hier zwei Hubseile, die über zwei Winden ablaufen, eingeschert werden.Another example showing a hook block 10 composed of the roller set modules 18 and 20 is apparent FIG. 3 , There, the roller set modules are oscillating connected to each other, so that in turn a rope length compensation can be done if here two hoisting ropes, which run over two winches, are reeved.

In der Figur 4 ist ein Beispiel der Hakenflasche 10 gezeigt, bei dem die beiden schmalen Rollensätze 22 und 24 zum Einsatz kommen. Sie sind in der hier dargestellten Art und Weise miteinander verbolzt. An diese kann eine Hakentraverse 16 mit Haken 12 angebolzt werden. Diese aus den schmalen Rollensätzen 22 und 24 zusammengesetzte Hakenflasche 10 kann zusammen mit einer Hakenflasche, wie sie beispielsweise anhand der Figur 2 dargestellt wurde, eingesetzt werden, wobei die Hakenflasche 10 entsprechend der Figur 2 an einer Hauptauslegerspitze eines Fahrzeugkrans eingesetzt wird, während diese gemäß Figur 4 dargestellte Hakenflasche als zweite weitere Hakenflasche an der Wippspitze eines Fahrzeugkrans zum Einsatz kommt. In diesem Einbaufall muss zwar ein zweiter Haken 12 eingesetzt werden, jedoch können die Rollensätze, wie sie ursprünglich in der Ausbaustufe gemäß Figur 1 vorgesehen waren und gegebenenfalls mitgeführt werden, modulartig miteinander verbunden werden, so dass die beiden Beispiele gemäß der Figur 2 und der Figur 4 entstehen und gleichzeitig bei einem Fahrzeugkran eingesetzt werden können.In the FIG. 4 an example of the hook block 10 is shown, in which the two narrow roller sets 22 and 24 are used. They are bolted together in the manner shown here. At this a hook traverse 16 can be angeolzt with hooks 12. This hook block 10 composed of the narrow sets of rollers 22 and 24 can, together with a hook bottle, as for example with reference to the FIG. 2 has been shown, the hook bottle 10 according to the FIG. 2 is used on a main jib tip of a vehicle crane, while this according to FIG. 4 Hook hook shown as the second additional hook bottle on the luffing tip of a vehicle crane is used. Although in this case a second hook 12 must be used, but the roller sets, as originally in the expansion stage according to FIG. 1 were provided and are possibly carried along, are connected in a modular manner, so that the two examples according to the FIG. 2 and the FIG. 4 arise and can be used at the same time in a vehicle crane.

Schließlich zeigt das Beispiel gemäß Figur 5 die Verwendung eines einzelnen schmalen Rollensatzes 22 mit einem kleinen Haken 12 und entsprechender Hakentraverse 16.Finally, the example according to FIG. 5 the use of a single narrow roller set 22 with a small hook 12 and corresponding hook beam 16.

Die hier dargestellten Kombinationsmöglichkeiten der modulartig aufgebauten Hakenflasche sind nur beispielhaft wiedergegeben. Es sind beliebig weitere Kombinationen möglich.The possible combinations of the modular hook hook shown here are only given by way of example. Any other combinations are possible.
