Description

Die Erfindung bezieht sich auf eine Verankerungseinrichtung für schwimmende Arbeitsgeräte, insbesondere für Schwimmbagger, mit einer bis in den Bereich unterhalb der Kiellinie absenkbaren, in einer vertikalen Führung am Schiffskörper gelagerten Höhenverstelleinrichtung für die Verholleine eines Ankers, vorzugsweise mit klappbaren Flunken.The invention relates to an anchoring device for floating implements, in particular for dredgers, with a height adjustment device, which can be lowered into the area below the keel line and is mounted in a vertical guide on the hull, for the anchorage of an anchor, preferably with foldable flunk.

Verankerungseinrichtungen dieser Art dienen dazu, die Verholleine beim Arbeiten in schiffbaren Gewässern derart tief unter Wasser bis zum Verankerungspunkt zu führen, dass der Schiffsverkehr nicht behindert wird. Zu diesem Zweck wird bei einer bekannten Verankerungseinrichtung (DE-C-963574) die Verholleine in einem Rohr geführt, das in einer vertikalen Führung längsverschiebbar am Schiffskörper gelagert ist und an seinen beiden Enden je eine Führungsrolle für die Verholleine aufweist. Der Nachteil solcher Verankerungseinrichtungen besteht vor allem darin, dass aufgrund der Führung der Verholleine durch ein höhenverstellbares Rohr der Anker beim Einholen von der Verholleine abgehängt und mittels eines Kranes auf Deck oder auf ein Hilfsboot gehoben werden muss, weil der Anker ja nicht durch das Führungsrohr gezogen werden kann. Die Neuverankerung eines Schiffes ist daher sehr umständlich und zeitraubend.Anchoring devices of this type are used to guide the mooring line so deeply under water to the anchoring point when working in navigable waters that the shipping traffic is not hindered. For this purpose, in a known anchoring device (DE-C-963574), the anchor line is guided in a tube which is mounted in a vertical guide on the hull and can have a guide roller for the anchor line at both ends. The main disadvantage of such anchoring devices is that due to the guiding of the anchor line through a height-adjustable tube, the anchor can be suspended from the anchor line when it is hauled in and lifted onto a deck or onto an auxiliary boat by means of a crane, because the anchor is not pulled through the guide tube can be. Anchoring a ship is therefore very cumbersome and time-consuming.

Um einen Anker in ein Klüsenrohr einziehen zu können, ist es bekannt (US-A-2937610), das Klüsenrohr teleskopartig auszubilden und den ausziehbaren Teil schraubverstellbar im festen Rohrteil zu führen, so dass der in den Einziehtrichter des ausziehbaren Klüsenrohrteiles eingreifende Anker bei seinem Einholen in eine bestimmte Einziehlage mit nach oben gerichteten Flunken gedreht wird. Mit Hilfe eines solchen Klüsenrohres lässt sich aber keine Verholleine unterhalb der Kiellinie so führen, dass der Schiffsverkehr unbehindert bleibt.In order to be able to pull an anchor into a tube, it is known (US-A-2937610) to design the tube telescopically and to guide the extractable part in a screw-adjustable manner in the fixed tube part, so that the anchor engaging in the pull-in funnel of the extractable tube part when it is being retrieved is turned into a certain drawing position with the flunk pointing upwards. With the help of such a wedge tube, however, it is not possible to guide a line below the keel line in such a way that shipping traffic remains unimpeded.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Verankerungseinrichtung der eingangs geschilderten Art so zu verbessern, dass der Anker ohne ein Abhängen von der Verholleine einfach eingeholt werden kann.The invention is therefore based on the object of improving an anchoring device of the type described at the outset in such a way that the anchor can be easily obtained without being detached from the catch line.

Die Erfindung löst die gestellte Aufgabe dadurch, dass am unteren Ende der Höhenverstelleinrichtung für die Verholleine ein Einziehtrichter für den Ankerschaft vorgesehen und vor die Mündung eines schräg im Schiffskörper angeordneten Klüsenrohres für die Verholleine anhebbar ist, wobei die Achsrichtung des Einziehtrichters mit der Achsrichtung des Klüsenrohres übereinstimmt. Da der Anker aufgrund dieser Massnahmen mit seinem Schaft in der Öffnung des Einziehtrichters Platz findet und der Einziehtrichter vor die Mündung eines Klüsenrohres angehoben werden kann, braucht der Anker beim Einholen nicht von der Verholleine abgehängt zu werden. Er wird vielmehr über die Verholleine in seine Einhollage eingezogen, wobei die schräge Achse des Einziehtrichters gewährleistet, dass sich die klappbaren Flunken des Ankers in einer nach aussen geklappten Stellung befinden, wenn der Anker mit seinem Schaft in die Öffnung des Einziehtrichters eintritt. Ausserdem ist durch die schräge Anordnung des Einziehtrichters die Reibung der darin geführten Verholleine am Ausgang des Einziehtrichters verringert.The invention solves this problem in that a retraction funnel for the anchor shaft is provided at the lower end of the height adjustment device for the retracting line and can be raised for the retraction line in front of the mouth of a chute tube arranged obliquely in the hull, the axial direction of the retracting funnel coinciding with the axial direction of the retractable tube . Since the anchor provides space for the anchor with its shaft in the opening of the pull-in funnel and the pull-in funnel can be raised in front of the mouth of a tube, the anchor does not have to be suspended from the catch line when it is pulled in. Rather, it is drawn into its pull-in position via the traction line, the inclined axis of the pull-in funnel ensuring that the hinged armature of the armature is in an outwardly folded position when the armature of the armature enters the opening of the pull-in funnel. In addition, the oblique arrangement of the feed hopper reduces the friction of the entrainment lines guided therein at the exit of the feed hopper.

Die Reibung der Verholleine kann zusätzlich dadurch herabgesetzt werden, dass die obere Begrenzung des Einziehtrichters für den Ankerschaft durch eine Rolle gebildet wird.The friction of the interlocking line can additionally be reduced in that the upper limit of the retraction funnel for the anchor shaft is formed by a roller.

Vorteilhaft kann auch am unteren Ende des Klüsenrohres eine Führungsrolle für die Verholleine gelagert sein, damit bei abgesenktem Einziehtrichter eine reibungsarme Führung für die Verholleine in diesem Bereich sichergestellt werden kann.A guide roller for the interlocking line can also advantageously be mounted at the lower end of the wedge tube, so that low-friction guidance for the interlocking line can be ensured in this area when the feed hopper is lowered.

In weiterer Ausgestaltung der Erfindung kann der Einziehtrichter innerhalb einer Nische am Rand des Schiffskörpers höhenverstellbar gelagert sein, wodurch die gesamte Verankerungseinrichtung innerhalb der Umrisslinie des Schiffskörpers zu liegen kommt. Ist dabei der Einziehtrichter an einem Rahmen befestigt, der sich mittels zweier Zylinder an einem am Schiffsdeck angeordneten Joch abstützt, so kann eine besonders robuste Ausführung erhalten werden.In a further embodiment of the invention, the draw-in funnel can be mounted in a height-adjustable manner within a niche on the edge of the hull, as a result of which the entire anchoring device comes to lie within the outline of the hull. If the feed hopper is fastened to a frame which is supported by means of two cylinders on a yoke arranged on the ship's deck, a particularly robust design can be obtained.

In der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel schematisch dargestellt. Es zeigen:

  • Fig. 1 einen Vertikalschnitt durch eine erfindungsgemässe Verankerungseinrichtung mit einem an der Verholleine eingeholten Anker,
  • Fig.2 eine der Fig. 1 entsprechende Darstellungsart der Verankerungseinrichtung, jedoch mit ausgelegtem Anker,
  • Fig.3 eine stirnseitige Ansicht der Verankerungseinrichtung und
  • Fig.4 das mit einer zusätzlichen Führungsrolle versehene untere Ende eines Klüsenrohres im Längsschnitt.
In the drawing, the object of the invention is shown schematically in one embodiment. Show it:
  • 1 shows a vertical section through an anchoring device according to the invention with an anchor that has been brought in on the catch line,
  • 2 shows a representation of the anchoring device corresponding to FIG. 1, but with the anchor designed,
  • 3 shows an end view of the anchoring device and
  • 4 shows the lower end of a wedge tube provided with an additional guide roller in longitudinal section.

Der Anker 1 der in einem Schiffskörper 2 untergebrachten Verankerungseinrichtung ist an einer Verholleine 3 angehängt, die durch ein Klüsenrohr 4 mit schräg verlaufender Achse bis zu einer Winde 5 verläuft. Als Führung für die Verholleine 3 dient ein Einziehtrichter 6, der an einem Rahmen 7 befestigt ist. Zur Höhenverstellung des Rahmens 7 sind im Schiffskörper 2 vertikale Führungen 8 vorgesehen. In der in Fig. 1 dargestellten oberen Endstellung fällt die Achse des Einziehtrichters 6 mit der Achse des Klüsenrohres 4 zusammen. In dieser Endstellung kann der Anker 2 an der Verholleine 3 an den Schiffskörper 2 soweit herangezogen werden, dass der Ankerschaft 9 in die Öffnung 10 des Einziehtrichters 6 passt.The anchor 1 of the anchoring device accommodated in a ship's hull 2 is attached to an interlocking line 3 which runs through a tapered tube 4 with an inclined axis up to a winch 5. A feed hopper 6, which is fastened to a frame 7, serves as a guide for the interlocking line 3. For vertical adjustment of the frame 7 2 vertical guides 8 are provided in the hull. In the upper end position shown in FIG. 1, the axis of the draw-in funnel 6 coincides with the axis of the wedge tube 4. In this end position, the anchor 2 on the interlocking line 3 on the hull 2 can be used to such an extent that the anchor shaft 9 fits into the opening 10 of the draw-in funnel 6.

Wie Fig.1 zeigt, besitzt der Anker 2 in bekannter Weise klappbare Flunken 11, die in der eingezogenen Lage des Ankers 1 wegen der Schräglage des Ankers 1 aufgrund ihres Eigengewichtes nach aussen geklappt sind. Dabei werden sie im allgemeinen die mit vollen Linien gezeichnete untere Stellung einnehmen. Es ist aber auch die strichpunktiert angedeutete obere Klappstellung der Flunken 11 möglich.As shown in FIG. 1, the armature 2 has foldable flunk 11 in a known manner, which in the retracted position of the armature 1 are folded outwards due to their own weight due to the inclined position of the armature 1. They generally become the un drawn with full lines Assume a lower position. However, the upper folding position of the flunk 11, indicated by dash-dot lines, is also possible.

Um eine reibungsarme Führung der Verholleine 3 bei der in Fig. 2 gezeichneten Lage des Einziehtrichters 6 sicherzustellen, ist die obere Begrenzung des Einziehtrichtes 6 durch eine Rolle 12 gebildet, um die die Verholleine 3 läuft. In gleicher Weise kann die Reibung der Verholleine 3 am unteren Ende des Klüsenrohres 4 durch eine Führungsrolle 13 verringert werden, wie dies in Fig. 4 gezeigt ist. Diese Führungsrolle 13 muss jedoch die untere Begrenzung der Klüsenrohrmündung bilden.In order to ensure low-friction guidance of the interlocking line 3 in the position of the drawing-in funnel 6 shown in FIG. 2, the upper limit of the drawing-in funnel 6 is formed by a roller 12 around which the interlocking line 3 runs. In the same way, the friction of the interlocking line 3 at the lower end of the tube 4 can be reduced by a guide roller 13, as shown in FIG. 4. However, this guide roller 13 must form the lower limit of the junction tube mouth.

Zur Höhenverstellung des Einziehtrichters 6 sind zwei Zylinder 14 vorgesehen, die einerseits an einem unteren Querholm 15 des Rahmens 7 und anderseits an einem Joch 16 angelenkt sind, das am Schiffsdeck errichtet ist. Damit die Konstruktion platzsparend und geschützt untergebracht werden kann, ist im Schiffskörper eine Nische 17 vorgesehen, deren Seitenwände in günstiger Weise die Führungen 8 für den Rahmen 7 tragen, der wie Fig. 3 zeigt, durch Streben 18 ausgesteift sein kann.To adjust the height of the feed hopper 6, two cylinders 14 are provided which are articulated on the one hand on a lower cross member 15 of the frame 7 and on the other hand on a yoke 16 which is erected on the ship deck. So that the construction can be accommodated in a space-saving and protected manner, a niche 17 is provided in the hull, the side walls of which advantageously carry the guides 8 for the frame 7, which, as shown in FIG. 3, can be stiffened by struts 18.
