Description

Bei der Erfindung handelt es sich um Doppelpolier von Hebeschiffen, deren Hebemechanismus so eingerichtet ist, daß die Polier mit der daran befestigten Hebetrosse quer über das Deck des I-lebeschiffes gezogen werden können und auf diese Weise das an den Hebetrossen hängende Wrack gehoben wird. Für diesen Zweck waren Doppelpolier der bisher üblichen Bauart nur in unvollkommener Weise geeignet, da sie, weil die Zugrichtung des Hebeseiles und die Zugrichtung der Poller-Bewegungseinrichtung im Belastungsfall bestrebt sind, miteinander in eine Fluchtlinie zu kommen, entweder einen starken, bewegungserschwerenden Seitendruck auf die Schienenanlage ausüben, auf der der Polier gleitet; oder aber dem Polier eine Schrägstellung geben, die für eine Gesamtanlage von dicht aneinandergedrängten 1 lebepollern unerwünschte Sperrigkeit zur Folge hat.The invention concerns double polishing of lifting vessels, whose lifting mechanism is arranged so that the polisher with the attached Lifting cables can be pulled across the deck of the I-lebeschiff and onto this Way, the wreck hanging on the lifting cables is lifted. For this purpose were Double polishing of the previously usual type of construction is only imperfectly suitable because they because the direction of pull of the lifting rope and the direction of pull of the bollard moving device endeavor to align with each other in the event of a load, either exert a strong side pressure on the rail system that makes movement difficult, on which the foreman slides; or give the foreman an inclination that undesirable for a complete system of 1 living bollards closely packed together Bulkiness.

Durch die Erfindung wird auf Grund der Anordnung, daß die eine Säule des Doppelpoliers mit einem Schlitz versehen ist, durch den das Hebeseil vor dem Belegen gelenkt wird, erzielt, daß die Poller-Längsachse aus dem Fluchtlinienverlauf nicht herausfällt.The invention is due to the arrangement that the one column of the double buffing machine is provided with a slot through which the lifting rope is inserted before the Evidence is steered, achieved that the bollard longitudinal axis is out of alignment does not fall out.

Die "Zeichnung zeigt in schematischer Darstellung ein Ausführungsbeispiel der Erfindung, und zwar in hig. i die Seitenansicht des frei über Deck bewegbaren Doppelpoliers gemäß der Erfindung und in Fig.2 und 3 die Draufsicht des Doppelpoliers gemäß der Erfindung, zusammengezeichnet mit der strichpunktiert angegebenen Lage eines frei über Deck bewegbaren Doppelpoliers normaler Bauart, und zwar in der Schrägeinstellung, die sich durch das Ausweichen des Poliers ergibt, das dann hervorgerufen wird, wenn das unter Last stehende Hebeseil in die Fluchtrichtung strebt, die durch die Zugeinrichtung, mit dem der Polier über Deck gezogen wird, gegeben ist. Es bedeutet darin: A Doppelpolier mit den beiden Poliersäulen B und C, D Schlitz in der Poliersäule C, E Hebeseil oder sonstiges Lastseil, F Zugeinrichtung am Polier, G Gleitgerüst für Polier, H normaler Polier.The "drawing shows a schematic representation of an exemplary embodiment of the invention, namely in hig. I the side view of the double polisher according to the invention, which can be moved freely over the deck, and in FIGS of a double polisher of normal design that can be moved freely over the deck, namely in the inclined position that results from the evasion of the polisher, which is caused when the lifting rope under load strives in the direction of escape caused by the pulling device with which the foreman is crossing It means: A double polisher with the two polishing columns B and C, D slot in the polishing column C, E lifting rope or other load rope, F pulling device on the foreman, G sliding frame for foreman, H normal foreman.

Durch den in der Doppelpoller-Längsachse in Poliersäule C angeordneten Schlitz D wird die Möglichkeit geschaffen, die Poller-Längsachse bei Belastung durch ein auf den Polier geführtes Seil in Fluchtrichtung mit der Poller-Zugeinrichtung zu halten.With the polishing column C arranged in the longitudinal axis of the double bollard Slot D creates the possibility of the longitudinal axis of the bollard when loaded a rope run on the foreman in the direction of escape with the bollard pulling device to keep.
