Description
Kran oder Bagger mit einem hydraulisch auf- und abbewegbaren Ausleger Es sind Krane mit hydraulisch betätigtem Ausleger bekanntgeworden, bei denen am Gerät ein mit dem Arbeitszylinder verschenes Rumpfstück angebracht ist, das mit einem abgeschrägten äußeren Anlegerteil derart in Verbindung steht, daß bei Drehen um 180' des an das Auslegerrumpfstück anschließbaren äußeren Auslegerteils um seine Längsachse der Ausleger eine andere abgewinkelte Stellung zur Achse des Auslegerrumpfstückes einnimmt.Crane or excavator with a hydraulically up and down boom Cranes with a hydraulically operated boom have become known in which a body piece with the working cylinder is attached to the device, which is connected to a beveled outer jib part in such a way that when rotated by 180 ' of the outer boom part that can be connected to the boom body section, the boom assumes a different angled position to the axis of the boom body section about its longitudinal axis.
Bei dieser Ausführung ist das äußere Auslegerteil stets abgewinkelt zum Auslegerrumpfstück angeordnet und kann nicht in eine gestreckte Lage gebracht werden, wodurch der Arbeitsbereich des Kranes oder Baggers bedeutend erweitert würde.In this embodiment, the outer boom part is always arranged at an angle to the boom body and can not be brought into a stretched position, which would significantly expand the working range of the crane or excavator.
Der Erfindung liegt die Aufgabe zugrunde, einen hydraulisch auf- und abbewegbaren. zweigeteilten Ausleger zu schaffen, dessen äußeres Auslegerteil durch Drehen um 180' von einer gestreckten in eine abgewinkelte Stellung zum Auslegerrumpfstück gebracht werden kann.The invention is based on the object of a hydraulically movable up and down. to create two-part boom, the outer boom part of which can be brought from a straight to an angled position to the boom body by rotating it 180 '.
Die Erfindung geht aus von Kranen oder Baggem mit einem hydraulisch auf- und abbewegbaren Ausleger, der aus einem mit dem hydraulischen Kraftgerät zum Anheben des Auslegers verbundenen Auslegerrumpfstück und einem äußeren Auslegerteil besteht, der mit dem Rumpfstück mit Hilfe von an beiden Auslegerteilen vorgesehenen Anschlußplatten verbunden ist.The invention is based on cranes or excavators with a hydraulic up and down boom, which consists of one with the hydraulic power device for Raising the boom connected boom body and an outer boom part exists, which is provided with the fuselage with the help of on both boom parts Connection plates is connected.
Erfindungsgemäß sind die Anschlußplatten gegen die Längsachsen der Auslegerteile um den gleichen Winkelbetrag derart geneigt, daß sich in der einen Anschlußlage des äußeren Auslegerteils ein gestreckter Ausleger, in der anderen Anschlußlage nach Drehung des äußeren Auslegerteils um dessen Längsachse um 1801 ein nach unten abgewinkelter Ausleger ergibt.According to the invention, the connecting plates are inclined to the longitudinal axes of the boom parts by the same angular amount in such a way that in one connection position of the outer boom part there is an elongated boom, in the other connection position after rotation of the outer boom part about its longitudinal axis by 1801 a downward angled boom results.
In den Zeichnungen ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt Fig. 1 den Anschluß des Auslegerrumpfstückes am Stützbock mit gekröpftem Ausleger, Fig. 2 den Anschluß des Auslegerrampfstückes am Stützbock mit geradem Ausleger.In the drawings, an embodiment of the invention is shown. It shows Fig. 1 the connection of the boom body piece on the support frame with a cranked boom, Fig. 2 the connection of the jib rump piece on the support frame with straight boom.
Am Lager 3 des Kranes ist der Arbeitszylinder 5 angebracht, der mit dem Auslegerrumpfstück 4, das im Lager 2 des Kranes 1 befestigt ist, in Verbindung steht. Das Auslegerteil 6 ist an einer schrägen Anschlußplatte 7, die zum Auslegerrumpfstück 4 gehört, so angeordnet, daß das Auslegerrumpfstück 4 mit dem Auslegerteff 6 einen gekröpften Ausleger bildet. Die Fig. 2 zeigt die Form des Auslegers nach Drehung des Auslegerteils 6 um 1801 und Befestigung an der Anschlußplatte 7 des Auslegerrumpfstückes 4. Dadurch bilden das Auslegerteil 6 und das Auslegerrumpfstück 4 einen geraden Ausleger.The working cylinder 5 is attached to the bearing 3 of the crane and is connected to the boom body section 4 which is fastened in the bearing 2 of the crane 1. The boom part 6 is arranged on an inclined connection plate 7, which belongs to the boom body section 4, in such a way that the boom body section 4 forms a cranked boom with the boom section 6. 2 shows the shape of the boom after rotating the boom part 6 by 1801 and fastening it to the connecting plate 7 of the boom body section 4. As a result, the boom part 6 and the boom body section 4 form a straight boom.
