Description
Die Erfindung betrifft einen Vibrationsstampfer zur Bodenverdichtung gemäß der im Oberbegriff des Anspruchs 1 angegebenen Art.The invention relates to a vibratory rammer for soil compaction according to the type specified in the preamble of
Ein Vibrationsstampfer der betreffenden Art ist z. B. aus der
Eine Aufgabe der Erfindung ist es, den aus der
Diese Aufgabe wird gelöst durch einen Vibrationsstampfer mit den Merkmalen des Anspruchs 1. Bevorzugte Weiterbildungen und Ausgestaltungen sind in den abhängigen Ansprüchen angegeben. Gemäß dem nebengeordneten Anspruch erstreckt sich die Erfindung auch auf einen Stampferfuß für die Verwendung an einem solchen Vibrationsstampfer.This object is achieved by a vibration tamper with the features of
Die Lösung der obenstehenden Aufgabe gelingt mit einem Vibrationsstampfer zur Bodenverdichtung, der einen Oberbau mit einem Antriebsmotor und einen Unterbau mit einer durch den Antriebsmotor angetriebenen Stampferplatte aufweist, wobei die Stampferplatte an einem zum Unterbau gehörenden Stampferfuß befestigt ist und dieser Stampferfuß mit (wenigstens) einem Führungselement linearbeweglich am Vibrationsstampfer gelagert ist. Es ist vorgesehen, dass der wenigstens eine Stampferfuß einteilig bzw. einstückig mit dem Führungselement ausgebildet ist. In anderen Worten heißt dies, dass der Stampferfuß mit einem integrierten Führungselement ausgebildet ist.The solution of the above object is achieved with a vibratory rammer for soil compaction, which has a superstructure with a drive motor and a substructure with a driven by the drive motor rammer plate, wherein the rammer plate is attached to a base belonging to Stampferfuß and this Stampferfuß with (at least) a guide element is mounted linearly movable on Vibrationsstampfer. It is provided that the at least one Stampferfuß is integrally formed or integrally with the guide element. In other words, this means that the Stampferfuß is formed with an integrated guide element.
Indem der Stampferfuß zusammen mit dem Führungselement einteilig bzw. einstückig ausgebildet ist, wird die Anzahl der herzustellenden und zu montierenden Einzelkomponenten gegenüber den aus dem Stand der Technik bekannten Konstruktionen, wie beispielsweise in der
Bei dem integrierten Führungselement handelt es sich um eine zylindrische bzw. rohrartige Innenführung einer Teleskopgleitführungseinrichtung handelt. Bislang wurden solche zylindrischen Innenführungen meist als Schweißteile hergestellt und anschließend mit dem Stampferfuß verbunden, wie beispielsweise in der
Erfindungsgemäß weist der Stampferfuß einen becherförmig ausgebildeten Abschnitt auf, der diese zylindrische Innenführung zumindest abschnittsweise umgibt. Ferner kann zwischen der Innenkontur des becherförmigen Abschnitts und der Außenkontur der zylindrischen Innenführung ein radialer Spalt vorhanden sein, wobei bevorzugt in diesem Spalt wenigstens ein sich zwischen der Innenkontur des becherförmigen Abschnitts und der Außenkontur der Innenführung erstreckender Verbindungssteg angeordnet ist. Durch diese Maßnahme kann ein besonders stabiler Aufbau erzielt werden. Der Verbindungssteg ist dazu bevorzugt ringförmig bzw. die Innenführung zwischen der Innenkontur des becherförmigen Abschnitts und der Außenkontur der Innenführung umlaufend ausgebildet. Auf Höhe dieses ringförmigen Verbindungsstegs kann ferner wenigstens eine Durchgangsöffnung vorhanden sein, die eine Verbindung zwischen dem Innenraum der Innenführung und dem den Stampfer umgebenden Außenraum herstellt.According to the invention, the tamper foot has a cup-shaped section which at least partially surrounds this cylindrical inner guide. Furthermore, between the inner contour of the cup-shaped portion and the outer contour of the cylindrical inner guide, a radial gap may be present, wherein preferably in this gap at least one extending between the inner contour of the cup-shaped portion and the outer contour of the inner guide connecting web is arranged. By this measure, a particularly stable structure can be achieved. The connecting web is preferably annular or the inner guide between the inner contour of the cup-shaped portion and the outer contour of the inner guide circumferentially formed. At the level of this annular connecting web, at least one through opening can also be present, which establishes a connection between the interior of the inner guide and the outer space surrounding the rammer.
Am Stampferfuß kann wenigstens ein großdimensionierter Transport- oder Haltegriff für den Vibrationsstampfer angeordnet sein, wobei dieser Transportgriff bevorzugt ebenfalls einteilig bzw. einstückig mit dem Stampferfuß ausgebildet ist.At the Stampferfuß can be arranged at least one large-sized transport or handle for the vibratory rammer, said transport handle is preferably also formed in one piece or in one piece with the Stampferfuß.
In vorteilhafter Weise ist der Stampferfuß als Ganzes, d. h. zusammen mit dem Führungselement und ggf. auch zusammen mit dem Transportgriff, als Gusskonstruktion ausgebildet. Als Gussmaterial wird vorrangig ein Aluminiumwerkstoff verwendet. Hierdurch kann ein geringes Gewicht erzielt werden. Ferner lässt sich vor allem das Führungselement, insbesondere im Vergleich zu einem Stahlwerkstoff, verhältnismäßig einfach spannabhebend nachbearbeiten. Durch die weniger aufwändige Bearbeitung kann eine Kostenoptimierung erreicht werden. Alternativ kann als Gussmaterial auch ein Kunststoffwerkstoff oder ein Kunststoffverbundwerkstoff verwendet werden. Ebenso ist möglich, dass es sich bei der Gusskonstruktion um einen Mehrkomponentenguss handelt, bei dem beanspruchungsgerecht unterschiedliche Gussmaterialien eingesetzt werden. So kann z. B. das Führungselement aus einem Stahlgusswerkstoff gebildet sein, während der restliche Stampferfuß aus einem Aluminiumwerkstoff besteht.Advantageously, the tamper foot as a whole, ie together with the guide element and possibly also together with the transport handle, designed as a cast construction. The casting material used is primarily an aluminum material. As a result, a low weight can be achieved. Furthermore, above all, the guide element, in particular compared to a steel material, can be reworked relatively easily spanabhebend. Due to the less time-consuming processing a cost optimization can be achieved. Alternatively, as a casting material and a plastic material or a plastic composite material may be used. It is also possible that the cast construction is a multi-component casting in which different casting materials are used in accordance with the requirements. So z. B. the guide element may be formed of a steel casting material, while the rest of the Stampferfuß consists of an aluminum material.
