Description

Anmelder."'ß't. cIioff, Rabr "--r--"."''.....". '' Jchlepphaken mit hydraulischer Betätigung Um beim Schleppen ein vollkommen sicheres Lösen der Schlepp- trosse vom Haken zu gewährleisten, bin ich entgegen der jetzigen vorhandenen Systeme, die ausschließlich die Haken durch das Auslösen von mechanischen Sperren zum Ausklinken (Abfallen des Hakens) bringen, auf eine neue Konstruktion nachfolgender Beschreibung gekommen : Alle mir bisher bekannten Systeme haben den Nachteile aß in Gefahrenmomenten die mechanischen Sperren durch die hohe Zuglast am Haken so verklemmen, daß sie nicht mehr ohne Gewalt- anwendung zu lösen sind. Liegt der Schlepper ungünstigenfalls quer zur Schlepplast und er, mann die Trosse nicht vom Haken lösen, ist er zum Kentern verurteilt (3 Schlepper in den letztenJahren im Hamburger Hafen). Der Schlepphaken mit hydraulischer Betätigung schließt diese Nachteile aus. Die Funktion ist folgende : Der Schlepphaken (1), nach beiliegender Zeichnung, ist in einer Traverse (2) gelagert. Bei (A) wird die Traverse (2) CD in den schon vorhandenen Teil der Schleppeinrichtung eingeschäkelt. Unter der Traverse ist der Druckzylinder (3) angebracht. Der Druckstempel (4) hält im ausgefahrenen Zustand dem Zug am Haken (1) den nötigen Widerstand. Eine flexible Stahlleitung (6) verbindet den Druckzylinder (3) mit der Druckpumpe (7) auf der Brücke, Der Haken (1) wird mittels Pumpe (7) über den Druckzylinder (3) und den Druckstempel (4) gegen das Widerlager (8) hoch gedrückt (Arbeitsstellung). Der Druckzylinder (3) steht während des Schleppbetriebes fortwährend unter Druck. Ein Manometer (9) an der Pumpe (7) auf der Brücke, zeigt die kleinste Druc&abweichung an. Applicant. "'Ss't. CIioff, Rabr "--r -". "''.....".'' Towing hook with hydraulic actuation To ensure a completely safe release of the towing To ensure the hawser from the hook, I came up with a new construction as follows, contrary to the current systems that only cause the hooks to disengage (the hooks fall off) by releasing mechanical locks: All systems known to me have the disadvantages ate In the event of danger, the mechanical locks jam due to the high tensile load on the hook in such a way that they can no longer be operated without force. application are to be solved. If, in the worst case, the tractor is lying down across the towing load and he, you don't get the hawser off the hook solve it, it is doomed to capsize (3 tugs in the last years in the port of Hamburg). The tow hook with hydraulic actuation eliminates these disadvantages. The function is as follows: The tow hook (1), according to the accompanying drawing, is in a traverse (2) stored. At (A) the traverse (2) CD Shackled in the already existing part of the towing device. The pressure cylinder (3) is attached under the crossbeam. The pressure ram (4) holds the necessary resistance to the pull on the hook (1) when it is extended. A flexible steel line (6) connects the pressure cylinder (3) with the pressure pump (7) on the bridge, the hook (1) is pushed against the abutment (8) by means of the pump (7) via the pressure cylinder (3) and the pressure stamp (4) ) pushed up (working position). The pressure cylinder (3) is continuously under pressure during the towing operation. A manometer (9) on the pump (7) on the bridge shows the smallest pressure deviation.

Beim Abwerfen des Schleppseiles (5) wird auf der Brücke das Druckablaßventil (10) an der Pumpe (7) geöffnet. Das Öl im Druckzylinder (3) wird durch die Last am Haken (1) durch den Druckstempel (4) in die Pumpe (7) zurück gedrückt. Das Zurück- gehen des Druckstempels (4-) erfolgt in a, 5-2 sec. Der Haken D (1) senkt sich erstens durch die Last am Haken (1) und zweitens durch die eigene Schwere in die Ausgangsstellung.When the tow rope (5) is dropped, the pressure relief valve (10) on the pump (7) is opened on the bridge. The oil in the pressure cylinder (3) is pushed back into the pump (7) by the load on the hook (1) through the pressure ram (4). The return going of the pressure stamp (4-) takes place in a, 5-2 sec. The hook D. (1) is lowered firstly by the load on the hook (1) and secondly by its own weight to the starting position.

Das Schleppseil (5) rutscht beim Niedergehen des Hakens (1) ab.The tow rope (5) slips when the hook (1) goes down.

Beim Wiederaufrichten des Hakens (1) in die Arbeitsstellung wird das DrucKablaßventil (10) an der Pumpe (7) auf der Brücke geschlossen. Durch ein paar Pumpenhübe wird der Druckzylinder (3) wieder auf vorgeschriebenen Druck gebracht, der ausfahrende Druckstempel (4) drückt den Haken (1) wieder gegen das Wiederlager (3) in Arbeitsstellung. Die Bedienung erfolgt von der Brücke aus.When the hook (1) is set up again in the working position, the The pressure relief valve (10) on the pump (7) on the bridge is closed. By a couple Pump strokes, the pressure cylinder (3) is brought back to the prescribed pressure, the extending plunger (4) presses the hook (1) against the abutment again (3) in working position. It is operated from the bridge.
