Description

Handstopferhand Topfer

Die Erfindung betrifft einen Handstopfer zum Unterstopfen von Schotter eines Gleises, bestehend aus einem einen Handgriff aufweisenden Antriebsmotor und einem daran anschließenden Stopfpickelrohr, in dem eine durch den Antriebsmotor um eine Rotationsachse rotierbare, mit einer Unwucht verbundene Unwuchtwelle gelagert ist, wobei zwischen Antriebsmotor und dem Stopfpickelrohr eine Schwingungsentkopplung angeordnet ist.The invention relates to a Handstopfer for Unterstopfen gravel a track, consisting of a handle having a drive motor and an adjoining Stopfpickelrohr in which a rotatable by the drive motor about a rotation axis, connected to an imbalance unbalanced shaft is mounted, wherein between the drive motor and the Stopfpickelrohr a vibration decoupling is arranged.

Ein Handstopfer ist aus der AT 239 296 bereits bekannt. Durch Distanzierung der Unwucht vom Antriebsmotor bzw. den Handgriffen wurde versucht, die Schwingungseinwirkungen auf die Bedienungsperson zu minimieren.A handstopper is from the AT 239 296 already known. By distancing the imbalance from the drive motor or the handles was trying to minimize the effects of vibration on the operator.

Aus der CN 1 600 991 A und der CN 101 173 491 A ist jeweils ein Handstopfer bekannt, der eine zwischen Antriebsmotor und Stopfpickelrohr angeordnete Schwingungsentkoppelung aufweisen. Diese ist als ringförmiger Schwingungsdämpfer ausgebildet, der den Antriebsstrang zwischen Antriebsmotor und Unwucht umschließt. Ein Austausch des Schwingungsdämpfers erfordert ein Lösen des Antriebsstranges.From the CN 1 600 991 A and the CN 101 173 491 A In each case, a hand stoppers are known, which have arranged between the drive motor and Stopfpickelrohr vibration decoupling. This is designed as an annular vibration damper, which surrounds the drive train between the drive motor and imbalance. An exchange of the vibration damper requires a loosening of the drive train.

Die Aufgabe der vorliegenden Erfindung liegt nun in der Schaffung eines Handstopfers der eingangs genannten Art, mit dem eine weitere Schwingungsreduktion im Bereich des Handgriffes erzielbar ist.The object of the present invention is now to provide a hand stuffer of the type mentioned, with which a further vibration reduction in the region of the handle can be achieved.

Diese Aufgabe wird erfindungsgemäß mit einem Handstopfer der gattungsgemäßen Art dadurch gelöst, dass zur Bildung der Schwingungsentkopplung das Stopfpickelrohr an einem oberen Ende Rohrfixierelemente aufweist und der Antriebsmotor Motorfixierelemente aufweist, die ausschließlich durch mehrere in Querrichtung zur Rotationsachse voneinander beabstandete Schwingungsdämpfer mit den Rohrfixierelementen verbunden sind und dass der Handgriff über weitere voneinander beabstandete Schwingungsdämpfer mit den Motorfixierelementen verbunden ist.This object is achieved with a hand stoppers of the generic type characterized in that the formation of the Vibration decoupling the Stopfpickelrohr at an upper end Rohrfixierelemente and the drive motor Motorfixierelemente which are exclusively connected by a plurality of transversely to the rotation axis spaced vibration damper with the Rohrfixierelementen and that the handle is connected via further spaced apart vibration damper with the Motorfixierelementen.

Mit einer derartigen Schwingungsentkopplung kann in Verbindung mit einer vom Antriebsmotor distanzierten Unwucht eine Übertragung der für die Verdichtung des Schotters erforderlichen Schwingungen auf den Handgriff wesentlich reduziert werden. Dies hat eine für die Bedienungsperson deutlich verringerte Belastung und Ermüdung zur Folge, ohne dass die Stopfqualität beeinträchtigt wird.With such a vibration decoupling, a transmission of the vibrations required for the compaction of the ballast to the handle can be substantially reduced in conjunction with an imbalance distanced from the drive motor. This results in a significantly reduced load and fatigue for the operator without affecting the quality of the stuffing.

Weitere Vorteile der Erfindung ergeben sich aus den Unteransprüchen und der Zeichnungsbeschreibung.Further advantages of the invention will become apparent from the dependent claims and the drawing description.

Im Folgenden wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher beschrieben. Es zeigen:In the following the invention will be described with reference to an embodiment shown in the drawing. Show it:

Ein in Fig. 1 ersichtlicher Handstopfer 1 besteht im Wesentlichen aus einem mit einem Handgriff 2 verbundenen Antriebsmotor 3 und einem an diesen anschließenden Stopfpickelrohr 4, das an einem unteren Ende 5 mit einer Stopfplatte 6 verbunden ist. Innerhalb des Stopfpickelrohres 4 ist eine durch den Antriebsmotor 3 um eine Rotationsachse 7 rotierbare Unwuchtwelle 8 gelagert. Diese ist im Bereich des unteren Endes 5 des Stopfpickelrohres 4 mit einer Unwucht 9 zur Erzeugung von für die Schotterverdichtung erforderlichen Stopfschwingungen verbunden.An in Fig. 1 apparent Handstopfer 1 consists essentially of a connected to a handle 2 drive motor 3 and an adjoining this stuffing pot 4, which at a lower end 5 with a Stopfplatte 6 is connected. Within the Stopfpickelrohres 4 a rotatable by the drive motor 3 about a rotation axis 7 imbalance shaft 8 is mounted. This is connected in the region of the lower end 5 of the Stopfpickelrohres 4 with an imbalance 9 for generating stuffing vibrations required for the ballast compaction.

Zwischen dem Antriebsmotor 3 und einem oberen, der Stopfplatte 6 gegenüberliegenden Ende 10 des Stopfpickelrohres 4 ist eine Schwingungsentkopplung 14 vorgesehen. Dazu weist das Stopfpickelrohr 4 am oberen Ende 10 Rohrfixierelemente 11 und der Antriebsmotor 3 Motorfixierelemente 12 auf. Diese sind ausschließlich durch Schwingungsdämpfer 13 mit den Rohrfixierelementen 11 verbunden.Between the drive motor 3 and an upper, the stuffing plate 6 opposite end 10 of the Stopfpickelrohres 4 a vibration decoupling 14 is provided. For this purpose, the stuffing needle 4 at the upper end 10 Rohrfixierelemente 11 and the drive motor 3 Motorfixierelemente 12. These are connected exclusively by vibration damper 13 with the pipe fixing elements 11.

Der Handgriff 2 ist über weitere Schwingungsdämpfer 15 mit den Motorfixierelementen 12 sowie mit Bedieneinrichtungen 16 zur Steuerung des Antriebmotors 3 verbunden.The handle 2 is connected via further vibration damper 15 with the Motorfixierelementen 12 and with controls 16 for controlling the drive motor 3.

Wie in Fig. 2 ersichtlich, ist die Unwuchtwelle 8 aus einem unteren, mit der Unwucht 9 verbundenen Wellenteil 17 und einem oberen, mit einer Antriebswelle 18 eines Getriebes bzw. des Antriebsmotors 3 verbundenen Wellenteil 19 gebildet. Beide Wellenteile 17, 19 sind unter Bildung einer gemeinsamen Rotationsachse 7 durch einen Schwingungsdämpfer 20 miteinander verbunden.As in Fig. 2 it can be seen, the imbalance shaft 8 is formed from a lower, connected to the unbalance 9 shaft part 17 and an upper, connected to a drive shaft 18 of a transmission or the drive motor 3 shaft part 19. Both shaft parts 17, 19 are connected to form a common axis of rotation 7 by a vibration damper 20 with each other.

Zwischen dem oberen Wellenteil 19 und der Antriebswelle 18 ist ein zweiter Schwingungsdämpfer 22 vorgesehen. Dieser ist in einer durch die Schwingungsentkopplung 14 gebildeten und normal zur Rotationsachse 7 verlaufenden Dämpfungsebene 21 positioniert. Beide Schwingungsdämpfer 20, 22 sind als elastische Kupplungen bekannter Bauart ausgebildet.Between the upper shaft part 19 and the drive shaft 18, a second vibration damper 22 is provided. This is in a through the vibration decoupling 14 positioned and normal to the axis of rotation 7 extending damping plane 21 positioned. Both vibration dampers 20, 22 are designed as elastic couplings of known design.

In einer alternativen Ausführung könnte aber auch anstelle der beiden Schwingungsdämpfer 20, 22 jeweils ein Kreuzgelenk vorgesehen werden.In an alternative embodiment but could also be provided instead of the two vibration dampers 20, 22 each have a universal joint.
