Description

Es ist l>ekannt, Lukenabdieckungen auf Schiffen mittels eines hydraulischen Antriebs, der drehbar an Deck befestigt ist, zu öffnen und zu schließen. Der hydraulische Antrieb greift entweder direkt an der Abdeckung an, oder der Antrieb wird durch Seile od. dgl. übertragen.It is not known to cover hatches on ships by means of a hydraulic drive that can be rotated Deck is attached to open and close. The hydraulic drive either engages directly on the Cover on, or the drive is transmitted by cables or the like.

Die Erfindung betrifft eine Verbesserung einer solchen Vorrichtung zum öffnen und Schließen der Lukenabdeckungen und besteht darin, daß der hydraulische Antrieb an einen Hebel angreift, dessen eines Ende mit dem die Luke umgebenden Deck mit Hilfe einer Drehachse verbunden ist, die außerhalb der Schwenkachse der Lukenabdeckung liegt, während sich das andere Ende des Hebels über die Oberseite der Lukenabdeckplatte erstreckt und mit dieser etwa in deren Schwerpunkt beweglich verbunden ist.The invention relates to an improvement of such a device for opening and closing the Hatch covers and is that the hydraulic drive acts on a lever, one of which The end is connected to the deck surrounding the hatch with the help of a pivot axis that extends outside the The pivot axis of the hatch cover lies, while the other end of the lever extends over the top extends the hatch cover plate and is movably connected to this approximately in the center of gravity.

Es ist bereits vorgeschlagen worden, die Vorrichtung zum öffnen und Schließen von Schiffslukendeckeln etwa in dem Schwerpunkt der Lukenabdeckplatte angreifen zu lassen. Hierbei war jedoch die Vorrichtung innerhalb des Lukensülls angeordnet. Da gemäß der Erfindung alle in der Konstruktion enthaltenen Teile außerhalb des Lukensülls liegen, sind sie leicht zugänglich, und ferner besteht nicht die Gefahr, daß die Last durch Lecköl Schaden erleidet.It has already been proposed the device for opening and closing ship hatches about to attack in the center of gravity of the hatch cover plate. Here, however, was the Device arranged within the hatch coamings. Since according to the invention all included in the construction If parts are outside the hatch coaming, they are easily accessible and there is no risk of that the load is damaged by leakage oil.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigtAn exemplary embodiment of the invention is shown in the drawing. It shows

Fig. 2 die gleiche Ansicht einer Abdeckung in zwei verschiedenen Öffnungslagen.2 shows the same view of a cover in two different opening positions.

Vom Deck 1 ragt in bekannter Weise ein Süll 2 nach oben, das die Laderaumöffnung umgibt. Auf diesem Süll liegen zwei Abdeckplatten 3 und 4, von denen die erstgenannte um an einer Seite' der Abdeckung befestigte Schwenkachsen 5 schwenkbar ist. Die Abdeckplatten sind in bekannter Weise durch Scharniere miteinander verbunden und werden bei der öffnungsbewegung mit ihren Unterseiten einander zugekehrt aufgeklappt. Die äußere Abdeckplatte 4 ruht dabei auf Rollen 6, die auf einer längs des Sülls angeordneten Bahn 7 laufen.From the deck 1 , a coaming 2 protrudes upwards in a known manner, which surrounds the cargo hold opening. On this coaming lie two cover plates 3 and 4, of which the former can be pivoted about pivot axes 5 attached to one side of the cover. The cover plates are connected to one another in a known manner by hinges and are opened with their undersides facing one another during the opening movement. The outer cover plate 4 rests on rollers 6 which run on a track 7 arranged along the coaming.

Die Vorrichtung zum öffnen und Schließen der Abdeckplatten besteht erfindungsgemäß aus einem Hebel 8 und einem hydraulischen Antrieb 9. Der Hebel ist am Deck mit Hilfe einer Drehachse 10 angelenkt, die parallel zu den Schwenkachsen der Abdeckplatte 3, aber außerhalb dieser und vorzugsweise auch etwas niedriger als diese liegt. Der Hebel erstreckt sich von seiner Drehachse über die Abdeckplatte 3 hinweg und ist mit dieser etwa in deren Schwerpunkt durch eine Einrichtung verbunden, die eine gegenseitige Bewegung zwischen Hebel und Abdeckplatte 3 in der Längsrichtung der Abdeckung Vorrichtung zum öffnen und Schließen der um eine oder beide der an den gegenüberliegenden SeitenkantenThe device for opening and closing the cover plates consists according to the invention of a lever 8 and a hydraulic drive 9. The lever is articulated on the deck with the aid of a pivot axis 10 which is parallel to the pivot axes of the cover plate 3, but outside this and preferably also slightly lower than this lies. The lever extends from its axis of rotation over the cover plate 3 and is connected to this approximately in its center of gravity by a device that allows a mutual movement between lever and cover plate 3 in the longitudinal direction of the cover device for opening and closing the around one or both of the on the opposite side edges

gestattet. Die Abdeckplatte 3 trägt eine in einem Bock gelagerte Rolle 11, unter die sich das Außenende des Hebels erstreckt. Dieses Hebelende ist als Rollbahn 12 ausgebildet. Die Rolle ist so weit oberhalb der Oberseite der Abdeckplatte angebracht, daß der Hebel, der in der Schließlage etwa parallel zur Abdeckplatte verläuft, beim Aufklappen der Abdeckplatte und rollender Drehung unter der Rolle 11 einen Winkel mit der Abdeckplatte bildet.allowed. The cover plate 3 carries a roller 11 mounted in a bracket, under which the outer end of the lever extends. This end of the lever is designed as a runway 12 . The roller is attached so far above the top of the cover plate that the lever, which in the closed position runs approximately parallel to the cover plate, forms an angle with the cover plate when the cover plate is opened and the roller 11 rotates by rolling.

Der hydraulische Antrieb ist zwischen dem Hebel und dem Deck unmittelbar neben dem Süll angebracht, so daß der Abstand zwischen der Hebeldrehachse und dem Angriffspunkt des Antriebes so groß wie möglich ist. Bei geeigneter Wahl der Lage der Drehachse 10 ergeben sich mäßige Abmessungen für den Antrieb und eine stabile Bauart der gesamten Vorrichtung.The hydraulic drive is mounted between the lever and the deck directly next to the coaming, so that the distance between the lever axis of rotation and the point of application of the drive is as large as possible. With a suitable choice of the position of the axis of rotation 10 , moderate dimensions for the drive and a stable design of the entire device result.

Die Abdeckplatte 3 ist zweckmäßig mit diagonalen Verstärkungsprofilen versehen, wobei die Rolle 11 gerade oberhalb des Schnittpunktes der Verstärkungsprofile angebracht ist. Für beide Abdeckplatten genügt ein einziger Hebel, der in der Mitte zwischen den Schwenkachsen 5 angeordnet ist. DieseSchwenkachsen liegen vorzugsweise etwas höher als die Ebene derThe cover plate 3 is expediently provided with diagonal reinforcement profiles, the roller 11 being attached just above the intersection of the reinforcement profiles. A single lever, which is arranged in the middle between the pivot axes 5 , is sufficient for both cover plates. These pivot axes are preferably slightly higher than the plane of FIG

Claims

1 cover plates in the closed position and so far outside the coaming that the cover plates in the unfolded position are in a known manner completely outside the loading space opening. The pivot axes of the cover plates are usually arranged lower than the plane of the cover in the closed position, but the cover plate hinged to the deck is located outside the pivot axis 5 in the opened position. Since the lever is still outside the cover plate, a large space is required behind the loading space opening, which can be disadvantageous if one wishes to arrange opening devices for two adjacent loading space openings next to one another. By arranging the pivot axes above the plane of the cover, it can be prevented that the cover plate 3 protrudes outwardly beyond the pivot axis 5, so that the space requirement is less. Since the cover plate and the lever are pivoted about different axes during the opening movement, as already mentioned, the outer end of the lever and the corresponding part of the cover plate, in the present case the roller 11, move towards one another, as best shown in FIG. 2 can be seen. The lateral distance between the two axes results from the desired length of the lever arm. The axis of rotation of the lever is preferably so much lower than the pivot axes that a line through the axes is inclined at an angle of approximately 45 ° to the deck plane. This results in the smallest mutual movement of parts 11 and 12. The connection shown can of course be replaced by any other that enables the desired movement, e.g. B. by a double joint. The winch can be designed as desired and provided with suitable control means. In order to facilitate the closing of the cover, part of the track 7 is designed in a known manner as a rising curve on which the roller 6 rolls upwards during the last part of the opening movement. In the unfolded position, the cover plates are locked with the aid of suitable devices. When the cover is closed after the cover plates have been unlocked, the rollers run down the curved track part, the cover plates moving into the closed position. After this movement has started, it can be braked with the aid of the drive so that it does not become too violent. In the case of covers that only consist of a single plate, it can be advantageous to use a drive which is effective in both directions and with the aid of which the plate is moved out of its vertical position.
