Description

Selbstbewegliches Rüttelgerät zur Bodenverdichtung Die Erfindung betrifft ein selbstbewegliches Rüttelgerät zur Bodenverdichtung mit zwei gleichsinnig umlaufenden Unwuchtwellen, deren Unwuchtmassen fest auf einer auf den Wellen axial verschiebbaren Lagerhülse sitzen.Self-propelled vibrating device for soil compaction The invention relates to a self-propelled vibrator for soil compaction with two rotating in the same direction Imbalance shafts, the imbalance masses of which are fixed on one axially displaceable on the shaft The bearing sleeve.

Bei einem bekannten Rüttelgerät werden die beiden Lagerhülsen auf den Unwuchtwellen durch ein gemeinsames Hebelgetriebe aus der gemeinsamen Längs-Mittelebene heraus nach einer Seite axial verschoben, um dem Rüttelgerät eine Kurvenfahrt zu ermöglichen. Durch das einseitige Verlagern der Unwuchtmassen wirkt die Vortriebskraftkomponente einseitig auf die Rüttelplatte, die sich um eine in der Mittelebene liegende Vertikalachse zu drehen sucht. Die bekannten Rüttler haben jedoch den Nachteil, daß die Lenkkomponente nur sehr gering ist. Außerdem ist die Rüttelplatte dabei einseitig belastet.In a known vibrator, the two bearing sleeves are on the unbalance shafts by a common lever mechanism from the common longitudinal center plane axially shifted out to one side in order to make the jogger turn enable. The propulsion force component acts through the one-sided shifting of the unbalanced masses one side on the vibrating plate, which is around a vertical axis lying in the central plane looking to turn. However, the known vibrators have the disadvantage that the steering component is only very low. In addition, the vibrating plate is loaded on one side.

Die Erfindung hat es sich zur Aufgabe gemacht, mittels der Achsverschiebung eine wirkungsvolle Lenkkomponente zu erzielen, und sieht die Lösung der Aufgabe darin, daß die auf den Lagerhülsen sitzenden Unwuchten durch ein an sich bekanntes gemeinsames Hebelgestänge gleichzeitig entgegengesetzt auf den Wellen axial verschiebbar sind.The invention has set itself the task by means of the axis shift to achieve an effective steering component, and sees the solution to the task in that the imbalances sitting on the bearing sleeves by a known per se common lever linkage at the same time axially displaceable in opposite directions on the shafts are.

Durch das entgegengesetzte Verschieben der Unwuchtmassen aus der Mittelebene des Unwuchtrüttlers wirkt die Vortriebskomponente auf der einen Plattenseite als linksdrehendes und auf der anderen Plattenseite als rechtsdrehendes Moment, wodurch die Lenkkomponente gegenüber den bekannten Geräten wesentlich wirkungsvoller ist. Außerdem wird die Rüttelplatte gleichmäßig belastet.By shifting the unbalanced masses in the opposite direction from the center plane of the unbalance vibrator, the propulsion component acts on one side of the plate as left turning and on the other side of the plate as a right turning moment, whereby the steering component is much more effective than the known devices. In addition, the plate compactor is evenly loaded.

An sich ist es bekannt, beim Eintreiben von Pfählen in den Boden mittels paarweise um waagerechte Achsen angeordneter, gegensinnig umlaufender Unwuchten Drehschwingungen zu erzeugen und auf den Pfahl zu übertragen. Hierbei stellt der Pfahl eine feste Drehachse dar, und die Drehschwingungen wechseln rhythmisch in ihrer Richtung, was der Lösung der Erfindungsaufgabe entgegensteht.It is known per se when driving piles into the ground by means of Imbalances rotating in opposite directions arranged in pairs around horizontal axes Generate torsional vibrations and transmit them to the pile. Here the Pile represents a fixed axis of rotation, and the torsional vibrations change rhythmically in their direction, which is contrary to the solution of the invention problem.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung schematisch dargestellt.An embodiment of the invention is shown schematically in the drawing shown.

In dem Maschinengestell 1, an dem eine nicht dargestellte Bodenplatte des Bodenverdichters angeordnet ist, sind zwei Unwuchtwellen 2, 3 in einer gemeinsamen Horizontalebene parallel zueinander gelagert. Die Unwuchtwelle 3 wird über ein Zahnrad 4 angetrieben. Die beiden Unwuchtwellen 2, 3 sind über ein nur teilweise durch die Zahnräder 5, 6 dargestelltes Zahnradgetriebe so miteinander gekuppelt, daß sie sich gegenläufig drehen.In the machine frame 1, on which a base plate, not shown of the soil compactor is arranged, two unbalanced shafts 2, 3 are in a common Horizontal plane stored parallel to each other. The unbalance shaft 3 is via a gear 4 powered. The two unbalanced shafts 2, 3 are only partially through the Gears 5, 6 illustrated gear transmission so coupled together that they turn in opposite directions.

Die Relativverdrehung zwecks Phasenseinstellung ist bei dem vorliegenden Rüttler ebenfalls möglich, jedoch nicht näher erwähnt, weil die Phasenverschiebung nicht zum Wesen der Erfindung gehört.The relative rotation for the purpose of phase adjustment is in the present one Vibrators are also possible, but not mentioned in detail because of the phase shift does not belong to the essence of the invention.

Auf den Unwuchtwellen 2 und 3 gleitet an den Keilführungen 7 und 8 jeweils eine Lagerhülse 9 und 10, auf denen die einzelnen Unwuchtmassen 11 und 12 angeordnet sind. Gehalten werden die Unwuchtmassen 11 und 12 durch Federn 13, 14, welche mittels Muttern 15, 16 gegeneinandergepreßt werden. Die Betätigung der Lagerhülsen 9 und 10 erfolgt durch ein Hebelgestänge 17, an dem Winkelhebel 18, 19 in Bolzen 20, 21 drehbar gelagert sind. Die Winkelhebel 18, 19 sind weiterhin an feststehenden Böckchen 22, 23 mittels Bolzen 24, 25 drehbar gelagert. An den Winkelhebeln sind weiterhin Zapfen 26, 27 angeordnet, die in Nuten 28, 29 der Hülsen 9 und 10 eingreifen.A bearing sleeve 9 and 10, on which the individual unbalanced masses 11 and 12 are arranged, slides on the wedge guides 7 and 8 on the unbalanced shafts 2 and 3. The unbalanced masses 11 and 12 are held by springs 13, 14, which are pressed against one another by means of nuts 15, 16. The bearing sleeves 9 and 10 are actuated by a lever linkage 17 on which angle levers 18, 19 are rotatably mounted in bolts 20, 21. The angle levers 18, 19 are also rotatably mounted on stationary lugs 22, 23 by means of bolts 24, 25. On the angle levers pins 26, 27 are also arranged, which engage in grooves 28, 29 of the sleeves 9 and 10.

Wird das Hebelgestänge 17 in der Zeichnungsebene nach unten bewegt, so verschieben sich die Unwuchtmassen 11 aus der Mittelebene 0-O nach rechts und die Unwuchtmassen 12 aus der Mittelebene 0-O nach links.If the lever linkage 17 is moved downward in the plane of the drawing, the unbalanced masses 11 move out of the central plane 0-0 to the right and the unbalanced masses 12 move out of the central plane 0-0 to the left.
