Description

Es ist ein Eisbrechgerät bekannt, das aus einem am Bug des Schiffes nach vorn über die Stevenkontur hinausragenden, in Schiffsbreite angebrachten, mit Greifern versehenen Schaufelrad besteht, das von einer 'besonderen Maschine im Vorschiff angetrieben wird. Von diesem Gerät ausgehend, werden beider Erfindung statt des Schaufelrades an sich für den Eisbrechdienst bekannte Raupenketten verwendet.An icebreaker is known which consists of one at the bow of the ship protruding forward over the stem contour, attached in ship's width, with The bucket wheel provided with grabs consists of a 'special machine in the foredeck is driven. Based on this device, both invention instead of the Bucket wheel used per se for the ice breaking service known caterpillars.

Hierbei hat die Erfindung sich zur Aufgabe gemacht, den Anstellwinkel der Raupenketten zur Eisfläche ändern zu können.Here, the invention has set itself the task of adjusting the angle of attack to be able to change the caterpillars to the ice surface.

Somit betrifft die Erfindung ein Eisbrechgerät; das am Bug eines Schiffes nach vorn über die Vorstevenkontur hinausragend angebracht ist und von einer besonderen Maschine im Vorschiff angetrieben wird. Die Erfindung besteht hierbei aus zwei an sich bekannten, mit Abstand nebeneinander angeordneten Raupen, die in einem Gerüst eingebaut und um eine horizontale, quer durch das Vorschiff unter der Wasserlinie verlaufende Antriebswelle schwenkbar sind, wobei die Gesamtbreite des Gerätes größer ist als die Schiffsbreite.The invention thus relates to an icebreaker; the one at the bow of a ship is attached to the front protruding beyond the Vorstevenkontour and of a special one Machine in the forecastle is driven. The invention consists of two known, spaced apart caterpillars that are in a scaffold built in and around a horizontal, across the foredeck below the waterline extending drive shaft are pivotable, whereby the overall width of the device is larger is than the ship's breadth.

Die Erfindung ist in der Zeichnung veranschaulicht (Abb. I und 2), die zeigt, daß an dem Vorschiff B eines Eisbrechers A ein Gerüst V mit Raupen C schwenkbar um die Welle D; über die auch der Antrieb erfolgt, befestigt ist. Der Anstellwinkel des Gerüstes und damit der Raupen wird mittels verstellbarer Haltestangen H geändert.The invention is illustrated in the drawing (Fig. I and 2), which shows that a scaffold V with caterpillars C on the forecastle B of an icebreaker A pivotable about shaft D; which is also used for the drive. Of the The angle of incidence of the scaffolding and thus of the caterpillars is adjusted by means of adjustable handrails H changed.
