Description

bezeichneten Hafenschlepper 1 und einem Leichter 2 dargestellt, der unterschiedliche Formen haben kann. Gemeinsam ist den Beispielen die Anordnung eines Druckgliedes 3 an dem einen Fahrzeug, z. B. dem Schlepper 1, und eines Schubpfostens 21, an dem anderen Fahrzeug, im Falle der Beispiele an der Heckseite des Leichters 2. Beiderseits angeordnete Kraftmittel zur Verschwenkung des Schleppers um eine senkrechte Achse relativ zum Leichter sind in beiden Ausführungsbeispielen als Seüzüge 7 und 8 angedeutet. Die Anlegungen der Seile befinden sich an den Stellen 10 und 11 möglichst weit nach außen am Heck des Leichters 2.designated port tug 1 and a barge 2 shown, which can have different shapes. Common to the examples is the arrangement of a pressure member 3 on the one vehicle, e.g. B. the Tractor 1, and a push post 21, on the other vehicle, in the case of the examples on the Rear side of the lighter 2. Power means arranged on both sides for pivoting the tractor by one The vertical axis relative to the lighter is indicated as Seüzüge 7 and 8 in both exemplary embodiments. The ropes are placed at points 10 and 11 as far outward as possible at the stern of the Lighter 2.

Bei dem in den Fig. 1, 2 und 3 gezeigten Ausführungsbeispiel ist am Druckglied 3 eine im Durchmesser verhältnismäßig große Rolle 20 angeordnet und der Schubpfosten 21 durch ein Rohr gebildet. Die Rolle 20 ist um eine horizontale Achse frei drehbar gelagert und weist eine halbkreisförmige Umfangsausnehmung 22 auf, die an beiden Seiten in Wulstränder übergeht und einen Radius aufweist, der größer als der Radius des den Schubpfosten 21 bildenden Rohres ist. Die Rolle 20 umschließt somit den Schubpfosten 21 teilweise, so daß die Übertragung von Querkräften möglich ist. Die Anlage der Rolle 20 am Schubpfosten 21 wird durch die Seilzüge 7 und 8 erreicht. Relativbewegungen um eine horizontale Längsachse werden durch einen mit seiner Drehkreisebene vertikal im Druckgiied 3 angeordneten Drehkranz 23 kompensiert, dessen einer Teil fest mit der Bugseite des Schleppers 1 und dessen anderer Teil fest mit den Lagern der Rolle 20 verbunden ist. Höhenunterschiede werden durch Abrollen der Rolle 20 am Schubpfosten 21 ausgeglichen. Bei Verschwenkungen des Schleppers gegenüber dem Leichter in Seitenrichtung wälzt sich die Rolle 20 ebenfalls entsprechend am Schubpfosten 21 ab.In the embodiment shown in FIGS. 1, 2 and 3, an im is on the pressure member 3 Diameter relatively large roller 20 is arranged and the thrust post 21 is formed by a tube. The roller 20 is mounted freely rotatable about a horizontal axis and has a semicircular circumferential recess 22, which merges into bead edges on both sides and has a radius that is greater than that The radius of the tube forming the thrust post 21 is. The roller 20 thus encloses the push post 21 partially, so that the transmission of transverse forces is possible. The installation of the roller 20 on the push post 21 is achieved by the cables 7 and 8. Relative movements around a horizontal longitudinal axis are made by a rotating ring 23 arranged with its rotating circle plane vertically in the die casting 3 compensates, its one part fixed to the bow side of the tractor 1 and the other part fixed to the bearings of the roller 20 connected is. Differences in height are compensated for by rolling the roller 20 on the push post 21. at Pivoting of the tractor relative to the lighter in the lateral direction rolls the roller 20 also correspondingly on the push post 21.

Das andere Ausfiihrungsbeispiel in den F i g. 4,5 und 6 zeigt einen Schubpfosten 21 in rJer Form eines Doppel-T-Profiles, so daß ein im horizontalen Querschnitt beidseitig hinterschnittenes Kopfprofil gebildet wird, welches ein entsprechend gestaltetes Druckglied 3 hintergreifen kann, um so gegebenenfalls Druckkräfte u.id Zugkräfte zu übertragen, welche z. B. bei der Rückwärtsfahrt eines Schubverbandes entstehen können. Im Ausführungsbeispiel sind an dem Druckglied 3 zwei um je eine senkrechte Achse 24 bewegliche Schwenkarme 25 gelagert, an deren Enden Rollen 26 und 27 um horizontale Achsen frei drehbar sind. Die Rollen 26 und 27 besitzen zylindrische Mantelflächen, die sich in Schubrichtung gegen die Innenfläche des einen Flansches und in Zugrichtung gegen die Innenfläche des anderen Flansches des den Schubpfosten 21 darstellenden Doppel-T-Profils legen. Die Schwenkarme 25 besitzen einen maschinellen Antrieb zum Ein- und Ausschwenken bei der Kupplung bzw. Entkupplung eines Schubverbandes. Als Antrieb eignen sich besonders Kolben-Zylinder-Einheiten 28 und 29, die mit einem Druckmittel beaufschlagt werden. Dm seitliche Schwenkbewegungen zu ermöglichen, ist bei diesem Ausführungsbeispiel eine um eine senkrechte Achse 30 bewegliche Lagerung des Schubpfostens 21 erforderlich. Zur besseren Übertragung größerer Schubkräfte ist eine runde bzw. ballige Gestaltung der dem Leichter zugewendeten Oberfläche des Schubpfostens 21 zweckmäßig, wie es mit dem Teil 31 angedeutet ist, so daß bei seitlichen Schwenkbewegungen stets ein Kontakt zwischen dem Schubpfosten 21 und der Heckseite des Leichters 2 auf ganzer Länge des Schubpfostens erhalten bleibt Der zu Fig.3 erläuterte Drehkranz 23 ist auch bei diesem Ausführungsbeispiel vorgesehen. Bei einer Anlenkung des Druckgliedes 3 mit einer horizontalen Gelenkachse 32 am Schlepper 1 sind zusätzliche, nicht gezeigte Mittel zur Einhaltung einer gleichbleibenden Höhenlage erfortf-rlich.The other exemplary embodiment in FIGS. 4,5 and 6 shows a push post 21 in the form of a double-T profile, so that a horizontal cross-section undercut head profile is formed on both sides, which a correspondingly designed pressure member 3 can reach behind in order to transfer compressive forces u.id tensile forces, which z. B. at the Reversing a push convoy can arise. In the exemplary embodiment, on the pressure member 3 two pivot arms 25, each movable around a vertical axis 24, with rollers 26 at their ends and 27 are freely rotatable about horizontal axes. The rollers 26 and 27 have cylindrical outer surfaces, which is in the pushing direction against the inner surface of one flange and in the pulling direction against the Place the inner surface of the other flange of the double-T profile representing the push post 21. the Swivel arms 25 have a mechanical drive for swiveling in and out of the coupling or Uncoupling of a push convoy. Piston-cylinder units 28 and 29, which be acted upon with a pressure medium. To enable lateral pivoting movements is at In this exemplary embodiment, a mounting of the push post 21 that is movable about a vertical axis 30 necessary. For better transmission of larger thrust forces, a round or spherical design is the The surface of the push post 21 facing the lighter is expedient, as indicated by the part 31 is, so that with lateral pivoting movements there is always contact between the thrust post 21 and the The rear side of the barge 2 is retained over the entire length of the push post Slewing ring 23 is also provided in this exemplary embodiment. When the pressure member 3 with a horizontal hinge axis 32 on the tractor 1 are additional, not shown means of compliance a constant altitude.
