Description

Die Erfindung betrifft eine Einrichtung zum Heben und Transportieren schwerer, im wesentlichen plattenförmiger Gegenstände, insbesondere Portalkran zum Anheben und Transportieren von Lukenabdeckungen auf Schiffen, mit einem beidseitig der plattenförmigen Gegenstände auf Schienen verfahrbaren Portal, mehreren mit dem Portal zusammenwirkenden, zur Arretierung bzw. Verlagerung an dem jeweiligen Gegenstand vorgesehenen Mitnehmern sowie mindestens einer Hubvorrichtung.The invention relates to a device for lifting and transporting heavy, essentially plate-shaped objects, in particular gantry cranes for lifting and transporting hatch covers on ships, with a portal that can be moved on rails on both sides of the plate-shaped objects, and several that interact with the portal, for locking or relocation the drivers provided for the respective object and at least one lifting device.

Schiffseigene Portalkrane (Gantrys) haben häufig die Aufgabe, schwere Lukendeckel mit Gewichten von 100 t und mehr zu heben und über einer geschlossenen Schiffsluke übereinander zu stapeln. Allgemein bekannt sind Lösungen in Form eines portalartigen Deckkranes mit hängenden Hydraulikzylindern, die über die Ringflächen des Zylinders die Last anheben. Das Einklinken der Zylinder in entsprechende Vorrichtungen am Lukendeckel und die Aufnahme der Horizontalkräfte durch Trimmen oder Krängung in Verbindung mit den auftretenden Beschleunigungskräften ist schwierig und aufwendig.On-board gantry cranes (gantries) often have the task of lifting heavy hatch covers with weights of 100 t and more and stacking them over a closed hatch. Solutions in the form of a portal-type deck crane with hanging hydraulic cylinders which raise the load via the ring surfaces of the cylinder are generally known. The latching of the cylinders in corresponding devices on the hatch cover and the absorption of the horizontal forces by trimming or heeling in connection with the acceleration forces that occur is difficult and complex.

Durch das deutsche Gebrauchsmuster 19 23 267 ist ein Hubwagendeck für Binnenschiffe aus wellenförmig oder trapezförmig profilierten Blechen bekannt. Mehrere Bahnen der profilierten Bleche sind durch untergenietete und untergeschweißte Winkel zu Deckelteilen zusammengefügt, die durch einen über den Deckelteilen laufenden Hubwagen mit Hubvorrichtung angehoben, seitlich verfahren und an beliebiger Stelle zu mehreren übereinander abgesetzt werden. Der Hubwagen ist auf seitlich der Bleche verlaufenden Schienen in Längsrichtung des Schiffes verfahrbar und mit Mitnehmern versehen, die unter die überstehenden Enden der Deckelteile greifen. Das Anheben erfolgt mittels eines Hydraulikzylinders in Verbindung mit einem Seilzug. Mit dieser Vorrichtung besteht lediglich die Möglichkeit, die relativ leichten Wellblechdeckel anzuheben und zu transportieren. Gegenstände, die u.U. mehr als 100 t wiegen können, sind durch diese Vorrichtung, insbesondere durch die aus Seilen gebildete Hubvorrichtung, nicht realisierbar. Darüberhinaus ist es hier erforderlich, daß die Lukendeckel über ihren Begrenzungsrand hinwegragen, damit die Mitnehmer des Hubwagens daruntergreifen und diesen somit anheben können. Für Lukendeckel, die unmittelbar mit der Begrenzungskante abschließen, ist diese Einrichtung nicht anwendbar.The German utility model 19 23 267 discloses a pallet truck deck for inland navigation vessels made of corrugated or trapezoidal profiled sheet metal. Several webs of the profiled sheets are joined together by riveted and welded-in angles to cover parts, which are lifted by a lifting truck with lifting device running over the cover parts, moved laterally and placed at several points on top of each other. The pallet truck can be moved in the longitudinal direction of the ship on rails running to the side of the sheets and is provided with drivers which engage under the protruding ends of the cover parts. The lifting takes place by means of a hydraulic cylinder in connection with a cable. With this device, there is only the possibility of lifting and transporting the relatively light corrugated metal covers. Objects that may weigh more than 100 t are not realizable by this device, in particular by the lifting device made of ropes. In addition, it is necessary here that the hatch covers protrude beyond their boundary edge so that the drivers of the lifting truck reach under it and can thus raise it. This device cannot be used for hatch covers that end directly with the boundary edge.

Durch die DE-PS 10 53 964 ist eine Vorrichtung zum Heben und Verfahren von Teilen einer Lukenabdeckung auf Binnenschiffen bekannt. Die Vorrichtung besteht aus je einem auf einer in Längsrichtung entlang dem Lukensüll auf jeder Schiffsseite verlaufenden Tragschiene rollenden mit dem zu hebenden Teil der Lukenabdeckung verbindbaren Hebezeug. Als Hebezeug dient je ein an gegenüberliegenden Seiten der Luke angeordneter galgenförmiger Kran, der mit seinem Fuß in bekannter Weise auf einer an Deck oder in dessen Nähe an dem Lukensüll angeordneten Tragschiene läuft, mit seiner Bedienungsseite zu der Luke hinweist und auf etwa halber Höhe mit einer horizontale Kräfte aufnehmenden Führungsrolle versehen ist, die in einer an dem oberen Rand des Lukensülls befestigten Stützschiene läuft. Zum Heben und Verfahren besonders schwerer, insbesondere in Längsrichtung des Schiffes großer Lukendeckel, eignet sich eine Vorrichtung, bei der jedes Hebezeug aus zwei miteinander verstrebten Krangalgen besteht. Nachteilig an einer solchen Vorrichtung ist festzustellen, daß nach erfolgtem Abheben des jeweiligen Lukendeckels Probleme bei der Handhabung dahingehend gebildet werden, daß die Horizontalkräfte, die durch Trimmen, Krängen und Beschleunigungskräfte gebildet werden, durch diese Vorrichtung kaum in die Tragkonstruktion eingeleitet werden können, es sei denn, daß die gesamte Lagerung (Vertikal- und Horizontalrollen) so versteift ausgebildet wird, daß sie in der Lage ist, die entsprechenden Kräfte aufzunehmen. Durch eine solche Maßnahme würde die gesamte Einrichtung wesentlich schwerer und auch schwieriger in der Handhabung werden. Darüberhinaus müssen bei einer solchen Vorrichtung auf dem Lukendeckel entsprechende Augen oder dgl. aufgeschweißt sein, damit mittels der Galgen ein entsprechendes Anheben überhaupt realisiert werden kann. Sind lediglich Ausnehmungen in den Seitenbereichen vorhanden, ist diese Vorrichtung nicht mehr einsetzbar.From DE-PS 10 53 964 an apparatus for lifting and moving parts of a hatch cover on inland vessels is known. The device consists of a lifting gear that can be connected to the part of the hatch cover that is to be lifted and that rolls on a mounting rail that runs in the longitudinal direction along the hatch filling on each side of the ship. As a hoist, a gallows-shaped crane arranged on opposite sides of the hatch, which runs with its foot in a known manner on a mounting rail arranged on deck or in the vicinity of the hatch sill, points with its operating side to the hatch and at about half height with one horizontal force-absorbing guide roller is provided, which runs in a support rail attached to the upper edge of the hatch. A device is suitable for lifting and moving particularly heavy hatch covers, particularly those that are large in the longitudinal direction of the ship, in which each lifting device consists of two crane gallows braced together. A disadvantage of such a device is that after the respective hatch cover has been lifted, problems in handling are formed in such a way that the horizontal forces which are formed by trimming, heeling and accelerating forces can hardly be introduced into the supporting structure by this device, unless it is because that the entire storage (vertical and horizontal rollers) is stiffened so that it is able to absorb the corresponding forces. Such a measure would make the entire facility much heavier and more difficult to use. In addition, with such a device, corresponding eyes or the like must be welded onto the hatch cover so that a corresponding lifting can be achieved at all by means of the gallows. If there are only recesses in the side areas, this device can no longer be used.

Der Erfindung liegt die Aufgabe zugrunde, eine im gattungsbildenden Teil des ersten Patentanspruches beschriebene Einrichtung dahingehend weiterzubilden, daß sie in der Lage ist, Lukendeckel unterschiedlichster Gestalt und Gewichte sicher aufzunehmen, ohne daß eine Bewegung der jeweiligen Lukendeckel, die durch die Schiffsbewegung oder aber die Fahrbewegung des Portales erzeugt werden, sich nachteilig auf die Konstruktion auswirkt.The invention has for its object to develop a device described in the generic part of the first claim to the extent that it is able to safely accommodate hatch covers of various shapes and weights without any movement of the respective Hatch covers, which are generated by the movement of the ship or the movement of the portal, adversely affect the construction.

Diese Aufgabe wird gemäß dem Kennzeichen des ersten Patentanspruches gelöst durch mindestens zwei seitlich der Gegenstände auf dem jeweiligen Fahrträger der Portale angeordnete, einseitig gelagerte Hebel, die im Bereich ihrer freien Enden mit in Richtung der der Gegenstände bewegbaren Mitnehmern versehen sind, wobei jeder Hebel mittels einer außerhalb der Mitnehmer am Hebel angreifenden Hubvorrichtung um seine Lagerstelle am Fahrträger schwenkbar ist.This object is achieved according to the characterizing part of the first claim by at least two levers which are arranged on the side of the objects on the respective carrier of the portals and are mounted on one side and are provided in the area of their free ends with carriers which can be moved in the direction of the objects, each lever being connected by means of a outside of the driver on the lever engaging lifting device is pivotable about its bearing on the chassis.

Vorteilhafte Weiterbildungen des Erfindungsgegenstandes sind den Unteransprüchen zu entnehmen.Advantageous further developments of the subject matter of the invention can be found in the subclaims.

Bei der vorgeschlagenen Lösung sind vorzugsweise vier Hebel (jeweils zwei auf einer Seite) auf den Fahrträgern eines Portalkranes bzw. Gantrys so angeordnet, daß die eine Seite der Hebel mit dem Fahrträger über zwei Lager verbunden ist. Die andere Seite des Hebels hat einen hydraulisch oder pneumatisch ausfahrbaren Bolzen, der in eine entsprechende Öffnung an der Luke eingreift. Die Öffnung kann hierbei durch je eine Ausnehmung in den Seitenflächen des Lukendeckels oder aber durch je ein aufgeschweißtes Auge gebildet sein. Ein Hydraulikzylinder drückt die Bolzenseite des Hebels bis zur maximalen Stapelhöhe, die zwischen 2 und 3 m betragen kann. Das Lukengewicht und sämtliche Horizontalkräfte können so über die Tragbolzen, Lager und Hydraulikzylinder aufgenommen werden. Eine Bewegung der Platten, Deckel oder Lukenabdeckungen ist beim Anheben und Verfahren auch bei Trimm- oder Krängbewegungen des Schiffes nicht mehr gegeben.In the proposed solution, four levers (two each on one side) are preferably arranged on the travel beams of a gantry crane or gantry in such a way that one side of the levers is connected to the travel beam via two bearings. The other side of the lever has a hydraulically or pneumatically extendable bolt that engages in a corresponding opening on the hatch. The opening can be formed by a recess in the side surfaces of the hatch cover or by a welded eye. A hydraulic cylinder pushes the pin side of the lever up to the maximum stack height, which can be between 2 and 3 m. The hatch weight and all horizontal forces can thus be absorbed via the support bolts, bearings and hydraulic cylinders. There is no longer any movement of the plates, covers or hatch covers when lifting and moving, even when the ship is trimming or lifting.

In der Regel liegen die Lukendeckel so auf der Luke, daß sie mit deren Begrenzungskanten abschließen. Hier bestehen beim Aufnehmen des Lukendeckels keine Probleme, den Lukendeckel mit dieser Vorrichtung, die beim Anheben einen Kreisbogen beschreibt, anzuheben.As a rule, the hatch covers lie on the hatch in such a way that they end with their boundary edges. Here there are no problems when picking up the hatch cover to lift the hatch cover with this device, which describes a circular arc when lifting.

Ist der Lukendeckel jedoch so innerhalb der Luke angeordnet, daß er mit deren Stirnfläche abschließt, so kann durch gezieltes Verfahren des Portales in Verbindung mit einem gleichzeitigen Anhebevorgang ein lineares vertikales Anheben des Lukendeckels realisiert werden.However, if the hatch cover is arranged within the hatch in such a way that it closes with the end face of the hatch, a linear vertical lifting of the hatch cover can be achieved by targeted movement of the portal in conjunction with a simultaneous lifting process.

Um eine gleichmäßige Betätigung der Hydraulikzylinder zu gewährleisten, werden diese von einer zentralen Steuereinheit gleichmäßig beaufschlagt.In order to ensure uniform actuation of the hydraulic cylinders, these are acted upon uniformly by a central control unit.

Die Erfindung ist nicht nur auf sogenannte Gantrys, d.h. Bordkrane, gerichtet, vielmehr besteht auch die Möglichkeit, diesen Portalkran an Land einzusetzen und ihn zum Anheben und Transportieren schwerer und schwerster Lasten zu verwenden, die sonst mittels anderer Krane nicht bewältigt werden können.The invention is not only applicable to so-called gantries, i.e. On-board cranes, straightened, there is also the possibility of using this gantry crane on land and using it to lift and transport heavy and heaviest loads that cannot otherwise be handled by other cranes.

Die erfindungsgemäße Hebevorrichtung 1, die an Bord eines nicht weiter dargestellten Schiffes angeordnet ist, besteht aus einem Portal 2, welches etwa mittig auf zwei Fahrträgern 3,4 angeordnet ist. Die Fahrträger 3,4 sind mit Fahrwerken 5,6,7 und 8 ausgebildet, die auf ebenfalls nicht dargestellten Schiene an Bord verfahrbar sind. Auf den Fahrträgern 3,4 sind die erfindungsgemäßen Hebevorrichtungen 9,10,11 und 12 befestigt. Der zu hebende Lukendeckel 13 ist der besseren Übersicht halber nur strichpunktiert dargestellt.The lifting device 1 according to the invention, which is arranged on board a ship, not shown, consists of a portal 2, which is arranged approximately in the middle on two carriers 3, 4. The travel carriers 3, 4 are designed with undercarriages 5, 6, 7 and 8, which can be moved on board on a rail, also not shown. The lifting devices 9, 10, 11 and 12 are fastened to the travel carriers 3, 4. The hatch cover 13 to be lifted is only shown in broken lines for the sake of a better overview.

Aufbau und Funktion der Einrichtungen 9-12 sind in den Figuren 2 und 3 dargestellt und werden anhand des Beispieles 9 erläutert. Die Hebevorrichtung 9 besteht aus einem Hebel 14, der im Bereich seines einen Endes 15 über zwei Lager 16,17 mit dem Fahrträger 3 gelenkig verbunden ist. Die Lagerachse 18 ist hierbei quer zu den Fahrträgern 3,4 gerichtet. Am freien Ende 19 des Hebels 14 ist ein Rohr 20 vorgesehen, das zur Aufnahme eines Bolzens 21 sowie eines Hydraulikzylinders 22 dient. Die Achse 23 des Bolzens 21 ist hierbei ebenfalls quer zum zugehörigen Fahrträger 3,4 angeordnet. Mittels des Hydraulikzylinders 22 kann der Bolzen 21 so weit ausgefahren werden, daß er in eine nicht weiter dargestellte Öffnung des Lukendeckels 13 hineingreift und diesen so arretieren. Zum Anheben des Lukendeckels 13 dient eine Kolben-Zylinder-Einheit 24, die einerseits etwa auf halber Höhe des Hebels 14 über ein Gelenk 25 verlagert ist. Die andere Seite des Zylinders 24 ist seitlich des zugehörigen Fahrträgers 3 über ein weiteres Gelenk 26 verlagert. Durch Ausfahren der Kolbenstange 27 kann der jeweilige Lukendeckel 13 auf dem Kreisbogen 28 angehoben werden. Durch Verfahren des Portales 2 bei gleichzeitigem Anheben des Lukendeckels 13 kann auch ein geradliniges Anheben des Lukendeckels 13 realisiert werden.The structure and function of the devices 9-12 are shown in FIGS. 2 and 3 and are explained using example 9. The lifting device 9 consists of a lever 14 which is articulated in the region of its one end 15 via two bearings 16, 17 to the travel carrier 3. The bearing axis 18 is directed transversely to the driving beams 3, 4. At the free end 19 of the lever 14, a tube 20 is provided, which serves to receive a bolt 21 and a hydraulic cylinder 22. The axis 23 of the bolt 21 is also arranged transversely to the associated travel carrier 3, 4. The bolt 21 can be extended so far by means of the hydraulic cylinder 22 be that he reaches into an opening (not shown) of the hatch cover 13 and lock it in this way. A piston-cylinder unit 24 is used to lift the hatch cover 13 and is displaced on the one hand about half way up the lever 14 via a joint 25. The other side of the cylinder 24 is moved laterally of the associated carrier 3 via a further joint 26. The respective hatch cover 13 can be raised on the circular arc 28 by extending the piston rod 27. By moving the portal 2 while simultaneously lifting the hatch cover 13, the hatch cover 13 can be lifted in a straight line.
