Description

Die Erfindung betrifft einen Spreader mit einer Schwerpunktausgleichseinrichtung, vorzugsweise zur Verladung von Containern in bzw. aus Schiffen.The invention relates to a spreader with a center of gravity compensation device, preferably for loading containers into or out of ships.

FUr den Containerumschlag werden in zunehmendem Maße Krane mit einfach- oder doppelhakigen Unterflächen eingesetzt. Zum leichteren Positionieren der Container in eine vorgegebene Stellung sind zwischen dem Kranhaken und den daran hängenden Spreadern Schwenk- oder Dreheinrichtungen vorgesehen, mit deren Hilfe eine darunter hängende Last von der Kanzel des Krans aus in beliebige Winkelpositionen um die Vertikalachse bewegt werden können. Bei diesen Kranen besteht jedoch der Nachteil, daß sich bei der Aufnahme eines exzentrisch beladenen Containers infolge der außermittigen Schwerpunktlage eine Schiefstellung des Containers einstellt. Derart schiefhängende Container können nur schwer oder gar nicht in die engen Schiffszellen der Containerschiffe eingeführt bzw. unmöglich infolge Verklemmungen aus den Schiffszellen herausgehoben werden.Cranes with single or double-hooked surfaces are increasingly used for container handling. To make it easier to position the containers in a predetermined position, swivel or rotating devices are provided between the crane hook and the spreaders attached to them, with the aid of which a load hanging underneath can be moved from the cockpit of the crane to any angular position about the vertical axis. The disadvantage of these cranes is that when an eccentrically loaded container is picked up, the container is skewed due to the off-center position of the center of gravity. Such skewed containers are difficult or impossible to insert into the narrow ship cells of the container ships or impossible to lift out of the ship cells due to jamming.

Um Schiefstellungen bei den Containern zu vermeiden, sind Spreader bekannt, bei denen ein Aufhängeturm auf einem Spreaderrahmen in dessen Längsrichtung verschiebbar angeordnet ist, wobei eine Verschiebung des Aufhängeturms soweit erfolgt, bis der Aufhängepunkt genau über dem Schwerpunkt des Containers liegt.In order to avoid skewing of the containers, spreaders are known in which a suspension tower is slidably mounted on a spreader frame in its longitudinal direction is arranged, the suspension tower being shifted until the suspension point lies exactly above the center of gravity of the container.

Zur Verschiebung des Aufhängeturmes ist es bekannt, hierfür einen Zylinder und zwei Kolbenstangen vorzusehen, wobei die herausragenden Enden der Kolbenstangen mit dem Spreaderrahmen und der Zylinder mit dem verschiebbaren Aufhängeturm fest verbunden sind. Die bei dieser Konstruktion erforderliche große Zylinderlänge weist den Nachteil auf, daß mit dem oftmals recht unsanften Aufsetzen des Spreaders auf einen Container eine unvermeidbare Durchfederung des Zylinder verbunden ist. Kolbenstangenbrüche und leckende Kolbenzylinderdichtungen sind die unmittelbare Folge. Ein weiterer Nachteil besteht darin, daß aufgrund der langen Verschiebewege des Zylinders lange SchlauchfUhrungen erforderlich sind, um den Zylinder mit dem Druckmittel zu versorgen.To move the suspension tower, it is known to provide a cylinder and two piston rods for this purpose, the projecting ends of the piston rods being firmly connected to the spreader frame and the cylinder being firmly connected to the displaceable suspension tower. The large cylinder length required in this construction has the disadvantage that the inevitably deflection of the cylinder is associated with the often very rough installation of the spreader on a container. Piston rod breaks and leaking piston cylinder seals are the immediate result. Another disadvantage is that, due to the long displacement of the cylinder, long hose guides are required to supply the pressure medium to the cylinder.

Zur Verschiebung des Aufhängeturmes ist es weiterhin bekannt, hierfür Gewindespindeln vorzusehen, die durch elektrisch angetriebene Getriebe gedreht werden. Auch bei dieser bekannten Konstruktion müssen die Spindeln entsprechend lang ausgebildet sein, um die geforderten Verschiebewege zu überbrücken. Festigkeitsprobleme sind auch hier vorhanden. Darüber hinaus ist diese Konstruktion aufwendig und teuer.To move the suspension tower, it is also known to provide threaded spindles that are rotated by electrically driven gears. In this known construction, too, the spindles must have a correspondingly long design in order to bridge the required displacement paths. Strength problems are also present here. In addition, this construction is complex and expensive.

Der Erfindung liegt die Aufgabe zugrunde, eine Konstruktion zu schaffen, bei der die Nachteile der bekannten Spreaderausführung vermieden sind.The invention has for its object to provide a construction in which the disadvantages of the known spreader design are avoided.

Zur Lösung der Aufgabe geht die vorliegende Erfindung von einem Spreader mit einem Spreaderrahmen und einem auf dem Rahmen mittels einer Kolben/Zylinder-Konstruktion verschiebbaren Aufhängeturm aus, wobei die kennzeichnenden Merkmale darin bestehen, daß eine vorgesehene Kolben/Zylinder-Ausführung mit einem Ende am verschiebbaren Aufhängeturm und mit dem anderen Ende an einem verschiebbaren Querträger befestigt ist, an dessen Enden sich jeweils eine weitere Kolben/Zylinder-Ausführung befindet, die mit einem Ende an dem Spreaderrahmen befestigt sind.To achieve the object, the present invention is based on a spreader with a spreader frame and a suspension tower which can be displaced on the frame by means of a piston / cylinder construction, the characterizing features being that an intended piston / cylinder version with one end on the displaceable Suspension tower and is attached at the other end to a displaceable cross member, at the ends of which there is a further piston / cylinder version, which are attached at one end to the spreader frame.

Durch die Erfindung ist ein Spreader vorhanden, mit dem Lasten mühelos bewegt werden können und der sich durch eine einfache und robuste Bauausführung auszeichnet.The invention provides a spreader with which loads can be moved effortlessly and which is characterized by a simple and robust construction.

Gemäß einer Ausführungsform der Erfindung ist es günstig, die Kolben/Zylinder-AusfUhrungen und den verschiebbaren Querträger in ein und derselben Horizontalebene vorzusehen. Hierdurch wird die Belastung des Querträgers mit Torsionsmomenten vermieden.According to one embodiment of the invention, it is advantageous to provide the piston / cylinder designs and the displaceable cross member in one and the same horizontal plane. As a result, the load on the cross member with torsional moments is avoided.

In weiterer Ausführung der Erfindung ist es zweckmäßig, wenn die druckmittelbeaufschlagten Flächen jeder der beiden äußeren Kolben/Zylinder-Ausführungen halb so groß gewählt sind, wie die druckmittelbeaufschlagten Flächen der innen liegenden Kolben/Zylinder-Ausführung, um die Verschiebegeschwindigkeit des Aufhängeturmes sowohl in die eine als auch in die andere Richtung in gleicher Größe zu belassen.In a further embodiment of the invention, it is expedient if the pressure-pressurized surfaces of each of the two outer piston / cylinder designs are selected to be half as large as the pressure-pressurized surfaces of the internal piston / cylinder design, in order to adjust the rate of displacement of the suspension tower in one as well as in the other direction in the same size.

Die Erfindung wird anhand eines in der Zeichnung dargestellten Ausführungsbeispiels im folgenden näher beschrieben. Die Zeichnung zeigt in:

Mit 1 ist ein Kranhaken bezeichnet, in den ein Aufhängeturm 2 eingehängt ist. Der Aufhängeturm 2 weist mehrere Gleitstücke 3 auf, die zwei T-Träger 4 in deren oberen Bereich umgreifen und die ein Verschieben des Hängeturmes 2 auf den T-Trägern 4 ermöglichen. Die T-Träger 4 sind auf einem Spreaderrahmen 5 aufgeschweißt. An dem Aufhängeturm 2 ist der Zylinder einer Kolben/Zylinder-AusfUhrung 6 angelenkt. Der Kolben der Kolben/ Zylinder-Ausführung 6 ist an einem ebenfalls auf den T-Trägern 4 verschiebbaren Querträger 7 angelenkt, an dessen Enden jeweils ein Kolben einer weiteren Kolben/Zylinder-Ausfuhrung 8 bzw. 9 angelenkt ist. Die Zylinder der Kolben/Zylinder-Ausführungen 8 und 9 sind an dem Spreaderrahmen 5 angelenkt. Die Kolben/Zylinder-Ausführung 6 weist zwei Druckmittelanschlüsse 10 und 11 auf. Bei der Kolben/Zylinder-Ausführung 8 sind Druckmittelanschlüsse 12 und 13 und bei der Kolben/Zylinder-Ausführung 9 Druckmittelanschlüsse 14 und 15 vorgesehen.1 with a crane hook is designated, in which a suspension tower 2 is suspended. The suspension tower 2 has a plurality of sliders 3 which grip around two T-beams 4 in their upper region and which allow the hanging tower 2 to be moved on the T-beams 4. The T-beams 4 are welded onto a spreader frame 5. The cylinder of a piston / cylinder version 6 is articulated on the suspension tower 2. The piston of the piston / cylinder version 6 is articulated on a cross member 7, which is also displaceable on the T-beams 4, at the ends of which a piston of a further piston / cylinder version 8 or 9 is articulated. The cylinders of the piston / cylinder versions 8 and 9 are articulated on the spreader frame 5. The piston / cylinder version 6 has two pressure medium connections 10 and 11. Pressure medium connections 12 and 13 are provided in the piston / cylinder version 8 and pressure medium connections 14 and 15 in the piston / cylinder version 9.

Die Funktionsweise des erfindungsgemäßen Spreaders ist folgende: Mit der Druckmittelversorgung des Druckmittelanschlusses 10 der Kolben/Zylinder-Ausführung 6 und gleichzeitiger Blockierung der Druckmittelanschlüsse 13 und 15 der Kolben/ Zylinder-Ausführungen 8 und 9 tritt eine Verschiebung des Aufhängeturmes 2 nach links ein. Der verschiebbare Querträger 7 bleibt in dieser Situation in seiner Lage bestehen. Die Rückführung des Aufhangeturmes 2 in die Mittelstellung erfolgt durch die Druckmittelversorgung des Druckmittelanschlusses 11 der Kolben/Zylinder-Ausführung 6.The operation of the spreader according to the invention is as follows: With the pressure medium supply to the pressure medium connection 10 of the piston / cylinder version 6 and simultaneous blocking of the pressure medium connections 13 and 15 of the piston / cylinder versions 8 and 9, the suspension tower 2 moves to the left. In this situation, the displaceable cross member 7 remains in its position. The suspension tower 2 is returned to the central position by supplying the pressure medium to the pressure medium connection 11 of the piston / cylinder version 6.

Soll eine Verschiebung des Aufhängeturmes 2 nach rechts erfolgen, werden die Druckmittelanschlüsse 12 und 14 der Kolben/Zylinder-Ausführungen 8 und 9 mit Druckmittel versorgt. Zur gleichen Zeit wird der Druckmittelanschluß 11 der Kolben/Zylinder-Ausfuhrung 6 blockiert, so daß mit der Verschiebung des Querträgers 7 nach rechts auch eine Verschiebung des Aufhängeturmes 2 nach rechts erfolgt. Die Ausführung des Aufhangeturmes 2 in die Mittelstellung geschieht dadurch, daß die Druckmittelanschlüsse 13 und 15 mit Druckmittel versorgt werden. In der Mittelstellung des Aufhängeturmes 2 sind dann alle Druckmittelanschlüsse 10, 11, 12, 13, 14, 15 blockiert, so daß der Aufhängeturm 2 in dieser Stellung fest arretiert ist und eine ungewollte Verschiebung unmöglich ist.If the suspension tower 2 is to be shifted to the right, the pressure medium connections 12 and 14 of the piston / cylinder versions 8 and 9 are supplied with pressure medium. At the same time, the pressure medium connection 11 of the piston / cylinder version 6 is blocked, so that with the displacement of the cross member 7 to the right, the suspension tower 2 is also displaced to the right. The execution of the suspension tower 2 in the middle position happens in that the pressure medium connections 13 and 15 are supplied with pressure medium. In the middle position of the suspension tower 2, all pressure medium connections 10, 11, 12, 13, 14, 15 are blocked, so that the suspension tower 2 is firmly locked in this position and an unwanted displacement is impossible.
