Description

Die Erfindung betrifft einen Schwimmsaugbagger mit an. dem freien Ende eines heb- und senkbaren und waagerecht schwenkbarein Auslegers gelagertem umlaufendem Schaufelrad, an dem sich eine längenveränderliiche Saugrohrleitung anschließt, die kugelgelenkig mit dem Baggerschiff verbunden ist.The invention relates to a floating suction dredger. the free end of a lifting and lowerable and horizontally pivotable in a cantilever mounted rotating paddle wheel, to which a variable-length suction pipe connects, the ball-and-socket joint is connected to the dredger.

Bei einem bekannten Schwimmsaugbagger dieser Art ist das Saugrohr kugelgelenkig an der Schiffswand befestigt und besteht aus zwei ineinanderschiebbaren Teilen. Der die Antriebsvorrichtung für das umlaufende Schaufelrad am freien Ende der Saugrohrleitung tragende Ausleger ist oberhalb des Kugelgelenkes lotrecht und waagerecht schwenkbar am Schiffskörper gelagert. Durch diese Anordnung ändert sich der Winkel zwischen Saugrohr und Ausleger beim Heben und Senken, weil die Schwenkachsen beider Teile nicht zusammenfallen. Dies hat zur Folge, daß sich das Grabwerkzeug entweder gegenüber dem Ausleger oder gegenüber dem Saugrohr verdrehen muß. Ersteres ist ungünstig für die Antriebseinrichtung, letzteres für den Anschluß des Grabwerkzeuges am 2S Saugrohr. In beiden Eällen ist die Lagerung des Schaufelrades ungünstig, da besondere . Vorrichtungen geschaffen werden müssen, um die beim Heben und Senken auftretenden Bewegungen des Schaufelrades auszugleichen, was bei dem unter Wasser arbeitenden Antrieb nicht einfach ist.In a known floating suction dredger of this type, the suction pipe is attached to the hull with a ball joint and consists of two parts that can be pushed into one another. The boom carrying the drive device for the rotating paddle wheel at the free end of the suction pipe is mounted on the hull above the ball joint so that it can pivot vertically and horizontally. This arrangement changes the angle between the suction tube and the boom when lifting and lowering, because the pivot axes of the two parts do not coincide. This has the consequence that the digging tool must rotate either with respect to the boom or with respect to the suction pipe. The former is unfavorable for the drive device, the latter for connecting the digging tool to the 2S suction pipe. In both cases, the storage of the paddle wheel is unfavorable because it is special. Devices have to be created to compensate for the movements of the paddle wheel that occur during lifting and lowering, which is not easy with the drive operating under water.

Nach der Erfindung wird vorgeschlagen, daß zwischen dem äußeren, mit dem heb- und senkbaren und waagerecht schwenkbaren Ausleger verbundenen Teil und dem längenveränderlichen Teil der Saugleitung ein weiteres Kugelgelenk eingeschaltet ist. Um auch mehrere Schnitte mit dem Gerät ausführen zu können, ohne das Baggerschiff vorzuschieben, ^0 ist es zweckmäßig, den das Schaufelrad tragenden Arm des kranartigen Gestelles in seiner Länge veränderlich auszugestalten.According to the invention it is proposed that between the outer part connected to the liftable and lowerable and horizontally pivotable boom and the variable-length part of the suction line, a further ball joint is switched on. In order to be able to make several cuts with the device without pushing the dredger forward, ^ 0 it is expedient to make the arm of the crane-like frame carrying the paddle wheel variable in length.

Durch die Erfindung werden die erwähnten Nachteile behoben. Darüber hinaus besteht noch weitgehende Freizügigkeit in der Anordnung der lotrechten Schwenkachse des schwenkbaren Auslegers. Es kann also dieThe disadvantages mentioned are eliminated by the invention. In addition, there is still extensive freedom of movement in the arrangement of the vertical pivot axis of the pivoting boom. So it can do the

Saugrohrleitung zweckdienlich an' dem unter Wasser befindlichen Teil der Schiffswand gelenkig angeschlossen werden, -während man bei der Lagerung des AuslegerS3 den man zweckdienlich am Oberdeck anordnet, auf die vorhandenen örtlichen Verhältnisse des Schiffes Rücksicht nehmen kann. Trotz dieser Freizügigkeit der Anordnung der Schwenkachsen der beiden voneinander unabhängigen ίο Teile kann die Schaufelradachse in dem Ausleger fest angeordnet sein.Suction pipeline expediently be connected to the underwater part of the ship's wall in an articulated manner, while when storing the boom 3, which is expediently arranged on the upper deck, the existing local conditions of the ship can be taken into account. Despite this freedom of arrangement of the pivot axes of the two mutually independent parts, the paddle wheel axis can be fixedly arranged in the boom.

Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel dargestellt.The invention is shown in the drawing in an exemplary embodiment.

Abb. 2 die Draufsicht dazu. In dem Baggerschiff a befindet sich die Saugleitung b, an der mittels eines Kugelgelenkes c die Saugleitung d, d1 angeschlossen ist, die an ihrem freien Ende das Schaufelrade in der üblichen Weise trägt. Der vordere Teilfii der Saugrohrleitung ist in dem hinteren Teil (P- längs verschieblich gelagert und enthält ein weiteres Kugelgelenk /. An Deck des Baggerschiffes α ist ein Schwenkgestell g um die Achse h mittels Zahnkranzes / nebst Ritzel k in waagerechter Ebene schwenkbar gelagert. Das Schwenkgestell g trägt einen Ausleger I, der mittels eines waagerechten Zapfens m mit ihm verbunden ist Und mittels des Seilzuges« in lotrechter Ebene schwenkbar ist. Das freie Ende des Auslegers / ist mit dem freien Ende des Saugrohresrf verbunden, so daß beim Heben und Senken des Auslegers I mittels des Seilzuges n auch die Saugrohrleitung d, dl mitgehoben und gesenkt wird. An dem Ausleger L ist die Antriebsvorrichtung 0 nebst Antriebsmaschine gelagert.Fig. 2 is a plan view of this. In the dredger a is the suction line b, to which the suction line d, d 1 is connected by means of a ball joint c, which carries the paddle wheel in the usual way at its free end. The front part fii of the suction pipe is mounted in the rear part (P- so that it can move lengthways) and contains another ball joint /. On the deck of the dredger α , a swivel frame g is swiveled about the axis h by means of a ring gear / together with a pinion k in a horizontal plane. The swivel frame g carries a boom I, which is connected to it by means of a horizontal pin m and can be swiveled in a vertical plane by means of the cable pull «. The free end of the boom / is connected to the free end of the suction tube so that when the boom is raised and lowered I the suction pipe d, d l is also raised and lowered by means of the cable pull n . The drive device 0 and the drive machine are mounted on the boom L.

Der Ausleger/ kann aus zwei Teilen bestehen, die gegeneinander verschiebbar sind, so daß mehrere Schnitte abgebaggert werden können, ohne daß das Baggerschiff vorgeschoben wird.The boom / can consist of two parts, which are mutually displaceable so that several cuts are excavated can without the dredger being pushed forward.
