Gemäß Fig. 6 wird von einem nicht dargestellten Motor einer Antriebswelle 1
des Stampfers angetrieben, die über ein Ritzel 2 eine in einem Stampfergehäuse
3 gelagerte und mit einer Außenverzahnung versehene Kurbelscheibe
4 antreibt. An der Kurbelscheibe 4 ist ein Hubzapfen 5 angebracht, auf den
ein Pleuel 6 drehbeweglich aufgesetzt ist. Das Pleuel 6 ist an seinem anderen
Ende mittels eines Kolbenbolzens 7 drehbeweglich mit einem Führungskolben
8 verbunden. Der Führungskolben 8 ist mit einer an ihm befestigten
Kolbenführung 9 innerhalb eines zur Untermasse gehörenden Führungsrohrs
10 in einem Führungszylinder 11 axial hin- und herbeweglich. Diese
Axialrichtung entspricht einer Vertikal- bzw. Arbeitsrichtung des Geräts
während seines Einsatzes.6, a
Auf beiden Seiten der Kolbenführung 9 ist ein aus einer oder mehreren Federn
bestehender Federsatz 12 angeordnet, wobei die Federn jeweils auf ihren
von der Kolbenführung 9 abgewandten Seiten gegen am Führungsrohr
10 befestigte Federplatten 13 abgestützt sind.On both sides of the
Das Führungsrohr 10 und die Federplatten 13 gehören zur Arbeits- bzw.
Untermasse des Stampfers. An der Untermasse kann ein in Fig. 6 nicht gezeigter
Stampffuß angebracht werden, der zur Bodenverdichtung dient. Um
das Eindringen von Feuchtigkeit und Schmutz zu vermeiden, sind die Obermasse
und die Untermasse durch einen elastischen Balg 14 verbunden.The

Im Stampfbetrieb treten außer den durch die Massebeschleunigung im Stampfsystem hervorgerufenen Schwingungen durch den Aufschlag der Stampfplatte auf den Boden - insbesondere bei sehr hartem, steinigem Boden - am Stampfer hohe Prellschläge auf. Dieses Problem wird bei relativ breiten Stampfplatten und die dadurch hervorgerufenen häufigen Schräglagen bzw. durch schräg auf die Stampfplatte wirkende Kräfte noch verstärkt.In pounding operation occur in addition to the mass acceleration in the Ramming system caused vibrations by the impact of the Ramming plate on the floor - especially on very hard, stony ground - high bumps on the tamper. This problem becomes relative wide ramming plates and the resulting inclined positions or exacerbated by forces acting obliquely on the ramming plate.
Die Prellschläge werden von der Stampfplatte auf das Führungsrohr und den Führungszylinder auf die Obermasse übertragen. Sie beeinträchtigen dadurch nicht nur eine gleichmäßige Schwingungsbeschleunigung der Obermasse. sondern können auch die Dauerhaltbarkeit der in der Obermasse eingebauten Teile, z.B. der Lager, der Verzahnungen und des Motors, erheblich beeinträchtigen. Zudem wirken sich die Prellschläge auch hinsichtlich der Handgriffabfederung negativ aus.The bumps are from the ramming plate on the guide tube and Transfer the guide cylinder to the upper mass. This affects you not only a uniform vibration acceleration of the upper mass. but can also increase the durability of the upper mass built-in parts, e.g. the bearings, the gears and the motor, considerably affect.

von Patentanspruch 1 angegeben. Vorteilhafte Weiterentwicklungen der
Erfindung sind den abhängigen Ansprüchen zu entnehmen.According to the invention, the solution is provided by an implement with the features
indicated by

According to the invention, a working device, in particular a ramming device for soil compaction or a hammer. with an upper mass that one in or on has a housing arranged drive, with one by the drive linearly back and forth via a motion converter and a spring set driftable working mass and with a guide device attached to the housing, the linear the working mass relative to the housing has leading guide cylinder, characterized in that the Guide cylinder attached to the housing with elastic mobility is, or the guide cylinder itself, otherwise rigid Connection that has the desired elastic flexibility.
Die elastische Beweglichkeit des Führungszylinders relativ zu dem zur Obermasse gehörenden Gehäuse beziehungsweise die elastische Beweglichkeit des Führungszylinders selbst ermöglichen eine wirksame Dämpfung der an der Arbeitsmasse auftretenden Prellschläge, insbesondere der nicht in Vertikalrichtung wirkenden Schläge. Schwingungstechnisch gesehen gehört zwar auch der Führungszylinder zur Obermasse; er wird jedoch erfindungsgemäß von der restlichen Obermasse entkoppelt, um einen wirksamen Abbau von Kraftspitzen zu ermöglichen.The elastic mobility of the guide cylinder relative to that of the upper mass belonging housing or the elastic mobility of the guide cylinder itself enable effective damping of the the impact masses occurring, in particular those not in the vertical direction acting blows.

Bei einer besonders vorteilhaften Ausführungsform der Erfindung sind zwischen dem Gehäuse und dem Führungszylinder ein oder mehrere elastische Elemente eingesetzt. Durch geeignete Auswahl der elastischen Elemente kann die gewünschte elastische Beweglichkeit zwischen Führungszylinder und Gehäuse einfach erreicht werden. Dabei ist zu beachten, daß die Elemente zwar einerseits die erforderliche Elastizität und einen entsprechenden möglichen Verformungsweg mit sich bringen müssen, andererseits aber muß der Führungszylinder nach wie vor steif mit dem Gehäuse verbunden sein. um ein Funktionieren des Arbeitsgeräts zu gewährleisten.In a particularly advantageous embodiment of the invention, between the housing and the guide cylinder one or more elastic Elements used. By suitable selection of the elastic elements can the desired elastic mobility between the guide cylinder and housing can be easily reached. It should be noted that the elements on the one hand the required elasticity and a corresponding one possible deformation path must bring, but on the other hand must the guide cylinder is still rigidly connected to the housing. to ensure that the implement works.
Daher kann auch eine andere Ausführungsform vorteilhaft sein, bei der der Führungszylinder aus Kunststoff besteht und ohne Zwischenlegen von elastischen Elementen direkt mit dem Gehäuse verbunden ist. Bei entsprechender Ausgestaltung eines am Führungszylinder vorgesehenen Befestigungsflansches wird die erforderliche Elastizität bereits durch das Kunststoffmaterial erreicht.Therefore, another embodiment can also be advantageous in which the Guide cylinder made of plastic and without the interposition of elastic Elements directly connected to the housing. With appropriate Design of a mounting flange provided on the guide cylinder the required elasticity is already due to the plastic material reached.
Bei einer besonders vorteilhaften Ausführungsform der Erfindung wird der Führungszylinder mittels eines Spannrings am Gehäuse festgehalten. Der Spannring ermöglicht es, die elastischen Elemente in einfacher Weise zwischenzulegen oder direkt den Befestigungsflansch eines aus Kunststoff bestehenden Führungszylinders zu halten.In a particularly advantageous embodiment of the invention, the Guide cylinder held on the housing by means of a clamping ring.

Die Fig. 1 bis 5 zeigen in Teilschnittdarstellung verschiedene Ausführungsformen der Erfindung. Soweit die Bauteile bereits anhand des bekannten Stampfgeräts nach Fig. 6 beschrieben worden sind, wird auf eine erneute Beschreibung verzichtet. Die Funktionsweise aller dargestellten Stampfgeräte ist identisch.1 to 5 show different embodiments in a partial sectional view the invention. So far the components based on the known 6 have been described, is on a new Description omitted. The functioning of all shown ramming devices is equal.
Die erfindungsgemäßen Stampfgeräte aus den Fig. 1 bis 5 zeichnen sich dadurch aus, daß ein Führungszylinder relativ zu einem Gehäuse elastisch beweglich ist.The ramming devices according to the invention from FIGS. 1 to 5 stand out characterized in that a guide cylinder is elastic relative to a housing is mobile.
In Fig. 1 ist ein Führungszylinder 20 zu sehen, an dem ein Befestigungsflansch
21 ausgebildet ist.In Fig. 1, a
An den als Befestigungsflächen 22 dienenden Stirnseiten des Befestigungsflansches
21 liegen sogenannte O- oder Rundschnurringe an, die als elastische
Elemente 23 dienen. Die Befestigungsflächen 22 bilden somit Berührflächen
mit den elastischen Elementen 23. Die elastischen Elemente 23 können
den Führungszylinder 20 mit konstantem Radius vollständig umgeben.
Sie können aber auch als einzelne Puffer am Umfang des Führungszylinders
20 verteilt sein. Ein Teil der elastischen Elemente 23 liegt an einer zum Gehäuse
3 gehörenden Anschlagfläche 24 an, während ein anderer Teil der elastischen
Elemente 23 durch einen mit dem Gehäuse 3 verschraubten und
als Befestigungseinrichtung dienenden Spannring 25 hintergriffen werden. On the end faces of the fastening flange serving as fastening surfaces 22
21 are so-called O or round cord rings, which are
Durch das Befestigen des Spannrings 25 am Gehäuse 3 werden die elastischen
Elemente 23 mit dem Befestigungsflansch 21 und dem Führungszylinder
20 fest mit dem Gehäuse 3 verbunden, wobei trotzdem eine gewisse elastische
Beweglichkeit zwischen dem Führungszylinder 20 und dem Gehäuse
3 bestehen bleibt. Diese Elastizität ist dazu geeignet, um durch Prellschläge
hervorgerufene Kraftspitzen abzubauen und dadurch die Obermasse vor
Schlägen wirksam zu schützen.By attaching the clamping
Fig. 2 zeigt eine andere Ausführungsform der Erfindung, bei der zusätzlich
zu der Lösung aus Fig. 1 der Spannring 25 einen Fortsatz 26 aufweist, der
ein weiteres elastisches Element 27 umschließt und gegen den Führungszylinder
20 drückt.Fig. 2 shows another embodiment of the invention, in
Diese Variante ermöglicht unter Beibehaltung der Elastizitätseigenschaften
eine noch steifere Verbindung zwischen dem Führungszylinder 20 und dem
Gehäuse 3, wodurch ein zu starkes seitliches Abknicken des Führungszylinders
20 gegenüber dem Gehäuse 3 vermieden werden kann.This variant enables the elastic properties to be retained
an even stiffer connection between the
Fig. 3 zeigt eine dritte Ausführungsform der Erfindung, bei der der aus Fig.
1 bekannte Befestigungsflansch 21 in zwei voneinander unabhängige Befestigungsflansche
28, 29 aufgeteilt worden ist, wobei jeder der Befestigungsflansche
28, 29 sich nur in einer Richtung gegen elastische Elemente 23 abstützt.Fig. 3 shows a third embodiment of the invention, in which the from Fig.
1 known mounting
Auch diese Lösung entspricht im Prinzip der ersten Ausführungsform gemäß
Fig. 1. Sie eröffnet jedoch die Möglichkeit, den Abstand zwischen den Befestigungsflanschen
28 und 29 beliebig zu vergrößern, um die Steifigkeit der
Verbindung zwischen dem Führungszylinder 20 und dem Gehäuse 3 zu vergrößern.In principle, this solution also corresponds to the first embodiment according to
Fig. 1. However, it opens up the possibility of the distance between the mounting
Diese Idee wird bei der vierten Ausführungsform der Erfindung gemäß Fig. 4
weiterentwickelt, bei der zwei weit auseinandergezogene Befestigungsflansche
30, 31 zu erkennen sind. Durch diese Anordnung lassen sich bei den
bisher beschriebenen Ausführungsbeispielen möglicherweise bei extremen
Belastungen auftretende seitliche Ausknickungen verhindern. This idea becomes apparent in the fourth embodiment of the invention according to FIG. 4
developed further, with the two widely spread mounting
In der vierten Ausführungsform gemäß Fig. 4 werden weiterhin statt der bisher gezeigten Rundschnurringe 23 elastische Elemente 32 gezeigt, die als gesondert anzufertigende Gummiformteile speziell für den Anwendungszweck angepaßt worden sind. Bei der in Fig. 4 gezeigten Ausführungsform decken die elastischen Elemente 32 nicht nur die Befestigungsflächen der Befestigungflansche 30, 31 ab, sondern auch die Umfangsflächen, wodurch insbesondere seitliche Stöße besser abgefangen werden können.In the fourth embodiment according to FIG. 4, instead of the previously used Cord rings shown 23 shown elastic elements 32, which as separately manufactured molded rubber parts especially for the application have been adjusted. In the embodiment shown in Fig. 4 cover the elastic elements 32 not only the mounting surfaces of the Fastening flanges 30, 31, but also the peripheral surfaces, whereby lateral bumps in particular can be better absorbed.
Eine fünfte Ausführungsform ist in Fig. 5 dargestellt.A fifth embodiment is shown in FIG. 5.
Der dort gezeigte Stampfer weist einen Führungszylinder 33 aus einem
Kunststoffmaterial auf. Der Kunststoff ist bereits so elastisch, daß bei einer
ansonsten starren Verbindung zwischen dem Führungzylinder 33 und dem
Gehäuse 3 die gewünschte elastische Beweglichkeit erreicht werden kann.
Dazu weist der Führungszylinder 33 - analog zu der vierten Ausführungsform
gemäß Fig. 4 - zwei Befestigungsflansche 34, 35 auf, die einen nicht
zu geringen Abstand voneinander haben sollten.The tamper shown there has a
Zur Erhöhung der Elastizität können in den Befestigungsflächen der Befestigungsflansche
34, 35 Ausnehmungen 36 ausgebildet sein, die die wirksamen
Befestigungsflächen verringern und somit die lokale Flächenpressung erhöhen,
wobei gleichzeitig innerhalb der Befestigungsflächen eine Erhöhung der
Elastizität erreicht wird.To increase the elasticity, the mounting flanges in the mounting surfaces

Neben der vorteilhaften Wirkung des Führungszylinders 33 hinsichtlich der
Dämpfung von Prellschlägen ergeben sich auch deutliche Gewichtsvorteile.
Darüber hinaus ist die Herstellung eines derartigen Kunststoffteils einfacher
als die Herstellung eines vergleichbaren Teiles aus Metall.In addition to the advantageous effect of the
