Abstract

Die Erfindung betrifft einen Vibrator zur Einwirkung auf Rammgut, mit einer Linearantriebseinheit (7) in Form zumindest eines Hydraulikzylinders, dessen zumindest eine Kolbenstange unter Einwirkung einer Steuerung (9) bezüglich eines die Linearantriebseinheit aufnehmenden Tragrahmens (6) geradlinig wechselweise hin und her bewegt wird und dabei ihre Schwingungsbewegungen auf ein mit dem Rammgut verbundenes Halteelement (3) überträgt, wobei die mittels der Linearantriebseinheit erzeugte Schwingungsfrequenz und die von ihr ausgehende Antriebskraft veränderbar sind.The invention relates to a vibrator for acting on piling, with a Linear drive unit (7) in the form of at least one hydraulic cylinder, the at least one piston rod under the action of a controller (9) with respect of a support frame (6) accommodating the linear drive unit in a straight line is alternately moved back and forth while doing theirs Vibration movements on one connected to the pile Holding element (3) transmits, the generated by means of the linear drive unit Vibration frequency and the driving force emanating from it can be changed are.

Mit der Erfindung wird der Vorschlag unterbreitet, die Linearantriebseinheit ausgangsseitig über die zumindest eine Kolbenstange an einem Außenrahmen (2) zu befestigen, der sich - relativ zum Tragrahmen (6) beweglich - in Richtung der Schwingungsbewegungen federnd an dem Tragrahmen (6) abstützt, wobei der Außenrahmen (2) einerseits das Halteelement (3) trägt und andererseits das Anbauteil für ein Trägergerät bildet.

Figure 00000001
With the invention, the proposal is made to fasten the linear drive unit on the output side via the at least one piston rod to an outer frame (2), which is movable relative to the supporting frame (6) and is resiliently supported on the supporting frame (6) in the direction of the oscillatory movements, whereby the outer frame (2) on the one hand carries the holding element (3) and on the other hand forms the attachment for a carrier device.
