Description

Grabenkettenbagger mit Drehbarkeit. der Lastradachse gegen den Oberbau in einer senkrecht zur Längsachse gerichteten Ebene mittels seitlicher Treibschraubspindeln. Die Erfindung richtet sich auf eine Lösung der Aufgabe, den Baggeroberbau mit der Eimerleiter so einstellbar zu machen, daß auch auf geneigtem oder gewelltem Boden die von dem Bagger zu ziehenden Gräben senkrechte Wandungen erhalten. Die Erfindung geht davon aus, daß die in unmittelbarer Nähe der Eimerleiter befindlichen, die Hauptlast aufnehmenden Räder mit ihrer Achse .durch Schraubspindeln in einer senkrecht zur Längsachse des Baggers gedachten Ebene drehbar sind, und sie kennzeichnet sich wesentlich dadurch, daß die beiden Treibschraubspindeln, um die Einstellung symmetrisch und einheitlich zu vollziehen, damit ferner das.Fahren und die Verstellung ohne starke Stöße und Beanspruchungen vonstatten gehen, die Achsenden zwischen Federn erfassen und von einer Vorgelegewelle aus zusammen gegenläufig gedreht werden.Trench chain excavator with rotatability. the load wheel axle against the superstructure in a plane perpendicular to the longitudinal axis by means of lateral drive screw spindles. The invention is directed to a solution to the problem of the excavator superstructure with the To make bucket ladder adjustable so that even on sloping or corrugated floors the trenches to be drawn by the excavator received vertical walls. The invention assumes that those in the immediate vicinity of the bucket ladder, the The main load-bearing wheels with their axis. By means of screw spindles in a vertical position are rotatable to the longitudinal axis of the excavator imaginary plane, and it is characterized essentially because the two drive screw spindles to make the setting symmetrical and to be carried out uniformly, so that also driving and adjusting without strong impacts and stresses take place, the axle ends between springs detect and are rotated together in opposite directions from a countershaft.

Auf der Zeichnung ist die Erfindung in einer Ausführungsform beispielsweise veranschaulicht.In the drawing, the invention is in one embodiment, for example illustrated.

Fig. z zeigt den Bagger im Aufriß auf ebenem Boden, Fig. a auf geneigtem Boden.Fig. Z shows the excavator in elevation on level ground, Fig. A on inclined Floor.

Auf die Achse a der Lasträder b, b stützen sich federnd die Schraubspindeln c, c, deren Muttern d, d im Querhaupt e des Oberbaues drehbar und unverschiebbar angeordnet sind. Durch Verstellen der Spindeln c, c läßt sich: der Oberbau um den Zapfen f der Achse a drehen, wie Fig. a veranschaulicht.The screw spindles c, c, the nuts d, d of which are rotatably and immovably arranged in the crosshead e of the superstructure, are resiliently supported on the axis a of the load wheels b, b. By adjusting the spindles c, c: the superstructure can be rotated about the pin f of the axis a , as Fig. A illustrates.

Die Spindeln c, c werden immer gleichzeitig tätig, und zwar so, daß sich die eine senkt, die andere hebt. Die Muttern für die Spindeln sind Innengewinde der Schneckenräder d, d, die von zwei Schnecken auf einer gemeinsamen Achse g, g umgetrieben werden. Die Welle g kann entweder von Hand gedreht oder auch maschinell von dem Motor aus angetrieben werden.The spindles c, c are always active at the same time, in such a way that one lowers, the other lifts. The nuts for the spindles are internal threads of the worm gears d, d, which are driven by two worms on a common axis g, g. The shaft g can either be rotated by hand or driven mechanically by the motor.

In letzterem Falle läßt sich die Anordnung so treffen, daß die Verstellung selbsttätig geschieht.In the latter case, the arrangement can be made so that the adjustment happens automatically.
