Description

gelagert sind. Der untere Abschnitt Ib jeder Stützstrebe ist mit Hilfe einer Gewindespindel 86 am freien Ende eines Querträgers 7 so schwenkbar gelagert, daß er noch quer zu deren Längsachse beweglich ist. Wie insbesondere aus Fig. 3 ersichtlich, ist jede Gewindespindel Sb oben in einer Führungsschelle 10 geführt, die Bestandteil eines Stützbockes 9 ist, der an dem freien Ende des Querträgers 7 lösbar befestigt ist.are stored. The lower section 1b of each support strut is pivotably mounted on the free end of a cross member 7 with the aid of a threaded spindle 86 so that it can still be moved transversely to the longitudinal axis thereof. As can be seen in particular from FIG. 3, each threaded spindle Sb is guided at the top in a guide clip 10 which is part of a support frame 9 which is releasably attached to the free end of the cross member 7.

Jeder Querträger 7 ist in seiner Querträgerführung ίο 6 a bzw. 6 b mit Hilfe eines nicht dargestellten hydraulischen Zylinders verschiebbar, so daß der Zwischenraum zwischen den unteren Enden der Stützstreben 2 wählbar ist. Die oberen Abschnitte 2 α der Stützstreben können durch lösbar ansetzbare Verbindungsstangen 14 miteinander verbunden werden, nachdem der Abstand der Stützstreben entsprechend gewählt ist. Dadurch bilden dann die oberen Stützstrebenabschnitte eine starre Einheit.Each cross member 7 is displaceable in its cross member guide ίο 6 a or 6 b with the aid of a hydraulic cylinder, not shown, so that the space between the lower ends of the support struts 2 can be selected. The upper sections 2 α of the support struts can be connected to one another by detachably attachable connecting rods 14 after the spacing of the support struts has been selected accordingly. As a result, the upper support strut sections then form a rigid unit.

F i g. 1 zeigt das voll aufgerichtete Rammgerüst in normaler Arbeitsstellung. Die Stützstreben 2 sind dabei gestreckt und in den Stoßstellen der Stützstrebenabschnitte an den Gelenken 11 beispielsweise durch Schraubenbolzen miteinander verriegelt. Aus dieser Normalstellung kann der Mäkler zur Durchführung besonders stark geneigter Rammarbeiten nach hinten abgeschwenkt werden, wobei er in der neuen Arbeitsstellung von den oberen Stützstrebenabschnitten gestützt wird. F i g. 2 zeigt den Mäkler in nach hinten geneigter Arbeitsstellung mit der am häufigsten erforderlichen Neigung von 45° gleich 1:1. Diese Arbeitsstellung wird hergestellt, indem der Mäkler 1 nach Entriegeln der Gelenke 11 unter Verstellen der Hubzylinder 15 so weit nach hinten geneigt wird, bis die unteren Enden der oberen Abschnitte 2 a der Stützstreben auf den Erdboden aufsetzen. Beim Neigen des Mäklers drehen sich die Querträger 7 innerhalb der Querträgerführungen 6 a, 6 b um ihre Längsachsen. Bei weichem Erdboden können die unteren Enden der oberen Abschnitte 2 α der Stützstreben 2 auf Bohlen 12 od. dgl. abgesetzt werden.F i g. 1 shows the fully erected ram structure in the normal working position. The support struts 2 are stretched and locked to one another in the joints of the support strut sections on the joints 11, for example by screw bolts. From this normal position, the leader can be swiveled backwards in order to carry out particularly steeply inclined pile-driving work, whereby it is supported in the new working position by the upper support strut sections. F i g. 2 shows the leader in a working position inclined to the rear with the most frequently required inclination of 45 ° equal to 1: 1. This work position is made by the leader 1 by unlocking the joints 11 so far inclined at adjusting the lift cylinder 15 to the rear, attach to the lower ends of the upper portions 2a of the support struts to the ground. When the leader tilts, the cross members 7 rotate about their longitudinal axes within the cross member guides 6 a, 6 b. In soft soil, the lower ends of the upper sections 2 α of the support struts 2 on planks 12 or the like. Are deposited.

Die Abmessungen der Stützstreben 2, insbesondere die Lage der Gelenke 11 der Stützstreben, sind beim Ausführungsbeispiel so gewählt, daß beim Aufstützen ihrer oberen Abschnitte 2 a auf den Erdboden eine Mäklerneigung von 45° hergestellt ist. Eine Feineinstellung der Mäklerneigung kann durch Verstellen der Spindeln 8 α bzw. 8 b erfolgen. Soll die Ramme mit in verschiedenen Winkelbereichen neigbarem Mäkler arbeiten können, so können die Stützstreben aus verschiedenen Teilabschnitten zusammensetzbar sein, deren Längen so vorgewählt sind, daß gewünschte Winkelstellungen des Mäklers erreicht werden. The dimensions of the support struts 2, in particular the position of the joints 11 of the support struts, are selected in the exemplary embodiment so that a leader inclination of 45 ° is produced when their upper sections 2a are supported on the ground. A fine adjustment of the leader's inclination can be done by adjusting the spindles 8 α and 8 b . If the ram is to be able to work with a leader that can be inclined in different angular ranges, the support struts can be assembled from different sections, the lengths of which are preselected so that the desired angular positions of the leader can be achieved.

Anders als im Ausführungsbeispiel dargestellt, kann das Fahrwerk des Arbeitsgerüstes selbstverständlich auf Rädern laufen und beispielsweise als Anhänger oder Selbstfahrlafette ausgebildet sein.In contrast to the illustrated embodiment, the chassis of the work scaffold can of course run on wheels and be designed, for example, as a trailer or self-propelled gun.
