Description

Die vorliegende Erfindung betrifft eine Rüttelvorrichtung zum Anbringen an einer Baumaschine oder ein Trägergerät. Die Rüttelvorrichtung wird oftmals auch als Rüttler bezeichnet.The present invention relates to a vibrator device for attachment to a construction machine or a carrier. The vibrator is often referred to as a vibrator.

Die Rüttelvorrichtung dient typischerweise zum Einbringen eines Gegenstands in den Boden. Beispielsweise ist es damit möglich sogenannte Spundbohlen, Spundwände oder Pfähle durch Ausführen einer Rüttelbewegung in das Erdreich einzubringen.The vibrator typically serves to introduce an article into the ground. For example, it is thus possible to introduce so-called sheet piles, sheet piles or piles by carrying out a shaking movement in the soil.

Beim Einbringen dieser Gegenstände in das Erdreich ist typischerweise ein Baugerät oder ein Trägergerät mit einem Mäkler versehen, an dem eine Rüttelvorrichtung vertikal zum Boden verfahrbar angeordnet ist. An der der Bodenfläche zugewandten Unterseite der Rüttelvorrichtung befindet sich üblicherweise eine Verbindungseinrichtung zum Halten der in das Erdreich einzutreibenden Gegenstände. Ferner dient die Verbindungseinrichtung zum Übertragen der von der Rüttelvorrichtung erzeugten Rüttelbewegung auf den in das Erdreich einzutreibenden Gegenstand.When these objects are introduced into the ground, a construction device or a carrier device is typically provided with a broker on which a vibrating device is arranged to be movable vertically to the ground. On the underside of the vibrating device, which faces the bottom surface, there is usually a connecting device for holding the objects to be driven into the ground. Furthermore, the connecting device serves for transmitting the vibrating movement generated by the vibrating device to the object to be driven into the ground.

Herkömmliche Rüttler weisen einen sehr hohen Verschleiß auf, was in Folge auch dazu führt, dass sehr hohe Wartungskosten anfallen und mit einem frühen Ausfall des Rüttlers gerechnet werden muss.Conventional vibrators have very high levels of wear, which in turn means that very high maintenance costs have to be incurred and an early failure of the vibrator must be expected.

Um ein Überhitzen der Rüttelvorrichtung zu verhindern, sieht der Stand der Technik FR2529292A1 vor, eine Getriebeölpumpe direkt auf der Erregerzelle der Rüttelvorrichtung anzubauen, wobei die Pumpe über eine Welle des Rüttlers angetrieben wird. Dabei ist ein Getriebeölkreislauf zwischen der Rüttelvorrichtung und dem die Rüttelvorrichtung tragenden Baugerät, das auch als Trägergerät bezeichnet wird, oder zwischen der Rüttelvorrichtung und einem sogenannten "Power-Pack" vorgesehen. Ein Power-Pack ist dabei eine von der Rüttelvorrichtung separate Einheit, die sämtliche Leitungen und Anschlüsse zum Betreiben der Rüttelvorrichtung versorgen kann. Typischerweise ist das Power-Pack am Boden angeordnet, kann aber auch an einem Baugerät befestigt sein. Das Power-Pack ist jedoch nicht zusammen mit der Rüttelvorrichtung am Mäkler verfahrbar. Das Getriebeöl wird dann über eine Schlauchverbindung zwischen dem Baugerät oder dem Power-Pack hin und zurückgefördert, wobei unter Umständen Schlauchlängen von bis zu 80 Metern überwunden werden müssen. Dadurch ist auch der Ölwechsel recht aufwändig, da nicht nur die Getriebezelle sondern auch die Schläuche und die Kühlvorrichtung auf der Baumaschine bzw. am Power-Pack entleert werden müssen. Auf der Baumaschine oder dem Power-Pack befindet sich ein Kühler mit dem das in der Rüttelvorrichtung erhitzte Getriebeöl gekühlt wird. Im Normalfall ist der Kühler ein herkömmlicher Öl-Luft-Kühler. Da die Pumpe auf einer Welle der Rüttelvorrichtung angeordnet ist, erfolgt eine Umwälzung des Getriebeöls nur beim Betrieb der Rüttelvorrichtung.To prevent overheating of the vibrator, the prior art provides FR2529292A1 To grow a gear oil pump directly on the excitation cell of the vibrator, wherein the pump is driven by a shaft of the vibrator. In this case, a transmission oil circuit between the vibrator and the jig carrying the construction equipment, which is also referred to as a carrier device, or provided between the vibrator and a so-called "power pack". A power pack is a unit separate from the vibrator, which can supply all lines and connections for operating the vibrator device. Typically, the power pack is arranged on the ground, but can also be attached to a construction equipment. However, the power pack can not be moved together with the jogger at the broker. The transmission oil is then pumped back and forth between the construction equipment or the power pack via a hose connection, with hose lengths of up to 80 meters possibly having to be overcome. As a result, the oil change is quite complex, since not only the transmission cell but also the hoses and the cooling device on the construction machine or power pack must be emptied. On the construction machine or the power pack is a cooler with which the heated in the vibrator gear oil is cooled. Normally, the radiator is a conventional oil-air cooler. Since the pump is arranged on a shaft of the vibrator, circulation of the transmission oil takes place only during operation of the vibrator.

Der Erfindung liegt nun die Aufgabe zugrunde, eine Vorrichtung anzugeben, die die eingangs beschriebene gattungsgemäße Rüttelvorrichtung unter anderem hinsichtlich einer Verbesserung ihrer Standzeit und einer Verminderung des sehr hohen Verschleißes vorteilhaft weiterbildet.The invention is based on the object of specifying a device which advantageously further develops the generic vibrator device described above, inter alia with regard to an improvement in its service life and a reduction in the very high degree of wear.

Die Lösung dieser Aufgabe erfolgt mit einer Rüttelvorrichtung, die die Merkmale des Anspruchs 1 umfasst.The solution of this object is achieved with a vibrator, comprising the features of claim 1.

Demnach weist die Rüttelvorrichtung zum Anbringen an ein Baugerät, insbesondere an einen Mäkler eines Baugeräts, eine Erregerzelle zum Erzeugen einer Rüttelbewegung, einen Anschluss für einen Ölablauf der Erregerzelle, einen Anschluss für eine Ölzufuhr der Erregerzelle, und eine Pumpe zum Fördern von Schmiermittel zwischen dem Anschluss für einen Schmiermittelablauf und dem Anschluss für eine Schmiermittelzufuhr auf. Ferner ist die Rüttelvorrichtung dadurch gekennzeichnet, dass die Pumpe über eine separate Leitung, vorzugsweise eine Druckleitung, antreibbar ist.Accordingly, the shaker device for attachment to a construction equipment, in particular to a leader of a construction equipment, an exciter cell for generating a shaking movement, a connection for an oil drain of the excitation cell, a connection for an oil supply of the exciter cell, and a pump for conveying lubricant between the terminal for a lubricant drain and the connection for a lubricant supply. Furthermore, the vibrating device is characterized in that the pump via a separate line, preferably a pressure line, can be driven.

Eine Rüttelvorrichtung oder auch ein Rüttler ist ein an ein Baugerät oder ein Trägergerät anbringbares Arbeitsgerät. Die Erregerzelle der Rüttelvorrichtung oder des Rüttlers beschreibt dabei die Einheit, die die Rüttelbewegung erzeugt. Diese ist mit einem Anschluss für einen Schmiermittelablauf und einem Anschluss für eine Schmiermittelzufuhr versehen. Darüber hinaus umfasst die Rüttelvorrichtung eine Pumpe, die dazu ausgelegt ist, Schmiermittel zwischen dem Anschluss für einen Schmiermittelablauf und dem Anschluss für eine Schmiermittelzufuhr der Erregerzelle zu fördern. Dabei kann die Pumpe über eine separate Leitung, vorzugsweise eine Druckleitung, betrieben werden. Als Pumpe sind sämtliche im Stand der Technik bekannten Pumpentypen verwendbar.A vibrating device or a vibrator is an attachable to a construction equipment or a carrier device working equipment. The excitation cell of the vibrator or vibrator describes the unit that generates the shaking motion. This is provided with a connection for a lubricant outlet and a connection for a lubricant supply. In addition, the vibrator device comprises a pump which is adapted to convey lubricant between the connection for a lubricant outlet and the connection for a lubricant supply of the exciter cell. The pump can be operated via a separate line, preferably a pressure line. As a pump, all known in the art pump types can be used.

Durch das Vorsehen einer separaten Leitung zum Antreiben der Pumpe ist es im Gegensatz zum Stand der Technik möglich, einen Schmiermittelkreislauf durch die Erregerzelle unabhängig vom Betrieb der Rüttelvorrichtung bzw. der Erregerzelle zirkulieren zu lassen. Dadurch ist es möglich, die Rüttelvorrichtung vorzuwärmen und den besonders verschleißintensiven Zustand eines Kaltstarts zu umgehen.By providing a separate line for driving the pump, in contrast to the prior art, it is possible to circulate a lubricant circuit through the excitation cell independently of the operation of the vibrator or the excitation cell. This makes it possible to preheat the vibrator and to avoid the particularly wear-intensive state of a cold start.

Vorzugsweise dient die Pumpe zum Antreiben eines Schmiermittelkreislaufs, der durch die Erregerzelle, den Anschluss für einen Schmiermittelablauf, die Pumpe und den Anschluss für eine Schmiermittelzufuhr verläuft.Preferably, the pump is for driving a lubricant circuit passing through the exciter cell, the lubricant drain port, the pump, and the lubricant supply port.

Dabei kann es zudem von Vorteil sein, wenn die Pumpe an dem Ziehjoch der Rüttelvorrichtung angeordnet und/oder befestigt ist. Dadurch ist die Pumpe nicht direkt den Vibrationen der Erregerzelle ausgesetzt und damit erhöht sich die Lebensdauer der Pumpe deutlich. Dadurch kann auch eine besonders platzsparende Anordnung der Pumpe verwirklicht werden. Das Ziehjoch ist ein Abschnitt der Rüttelvorrichtung zum Befestigen an einem Baugerät, insbesondere an einen Mäkler eines Baugeräts. An dem Ziehjoch wird die Rüttelvorrichtung vertikal zur Bodenebene verfahren.It may also be advantageous if the pump is arranged and / or attached to the draw yoke of the vibrator. As a result, the pump is not directly exposed to the vibrations of the excitation cell and thus significantly increases the life of the pump. As a result, a particularly space-saving arrangement of the pump can be realized. The draw yoke is a portion of the shaker device for attachment to a construction equipment, in particular to a leader of a construction equipment. At the Ziehjoch the vibrator is moved vertically to the ground level.

Nach einem weiteren optionalen, vorteilhaften Merkmal der vorliegenden Erfindung umfasst die Rüttelvorrichtung ferner einen Wärmetauscher, insbesondere einen Plattentauscher, zum Regulieren der Temperatur des durch die Pumpe förderbaren Schmiermittels. Vorzugsweise dient die Pumpe zum Antreiben eines Schmiermittelkreislaufs, der durch die Erregerzelle, den Anschluss für einen Schmiermittelablauf, die Pumpe, den Wärmetauscher und den Anschluss für eine Schmiermittelzufuhr verläuft. Dabei ist unerheblich, in welcher Reihenfolge die vorstehend genannten Bauteile in dem Schmiermittelkreislauf angeordnet sind.According to a further optional advantageous feature of the present invention, the vibrating device further comprises a heat exchanger, in particular a plate exchanger, for regulating the temperature of the lubricant to be pumped by the pump. Preferably, the pump is for driving a lubricant circuit passing through the exciter cell, the lubricant drain port, the pump, the heat exchanger, and the lubricant supply port. It is irrelevant in which order the aforementioned components are arranged in the lubricant circuit.

Vorzugsweise weist der Wärmetauscher einen ersten Kreislauf zum Durchströmen von durch die Pumpe zu fördernden Schmiermittel auf sowie einen zweiten Kreislauf, der dazu ausgelegt ist, mit einem Temperaturreguliermedium den ersten Kreislauf in seiner Temperatur zu regulieren. Als Temperaturreguliermedium kommt insbesondere ein Schmiermittel oder ein Hydraulikschmiermittel infrage. Es ist jedoch auch vorstellbar, dass ein anderes geeignetes Fluid durch den zweiten Kreislauf des Wärmetauschers strömt.Preferably, the heat exchanger has a first circuit for flowing through the pump to be conveyed lubricant and a second circuit which is adapted to regulate the temperature of the first circuit in its temperature with a temperature regulating medium. As a temperature control medium is in particular a lubricant or a hydraulic lubricant in question. However, it is also conceivable that another suitable fluid flows through the second circuit of the heat exchanger.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung weist der zweite Kreislauf des Wärmetauschers Versorgungsanschlüsse für ein Zu- und ein Ablaufen eines Temperaturreguliermediums auf. Dabei ist von Vorteil, wenn die Versorgungsanschlüsse für ein Zu- und ein Ablaufen an der Rüttelvorrichtung angeordnet sind.According to a further advantageous embodiment of the invention, the second circuit of the heat exchanger supply connections for a supply and a drainage of a Temperaturreguliermediums. It is advantageous if the supply connections for an inlet and a drain are arranged on the vibrator.

Dadurch ist es möglich eine Vielzahl von Vorteilen gegenüber den herkömmlichen Rüttelvorrichtungen im Stand der Technik zu erreichen.This makes it possible to achieve a variety of advantages over the conventional vibrators in the prior art.

Durch Vorsehen des Wärmetauschers und der von dem Betrieb der Rüttelvorrichtung unabhängigen Pumpe ist es möglich, eine Kühlung zwischen den Einschaltzeiten der Rüttelvorrichtung vorzunehmen und somit eine während eines Arbeitsbetriebs erreichte Temperatur der Rüttelvorrichtung zügig zu senken. Auch sind insgesamt längere Einsatzzeiten erreichbar bevor eine Überhitzung der Rüttelvorrichtung droht. Der Schmiermittelkreislauf durch die Erregerzelle ist nicht länger an den Betrieb der Erregerzelle gekoppelt. Ein Abkühlen des in der Erregerzelle verwendeten Schmiermittels kann daher auch in Betriebspausen durch ein Durchleiten durch den Wärmetauscher beschleunigt werden.By providing the heat exchanger and the pump independent of the operation of the vibrator, it is possible to perform cooling between the on-times of the vibrator and thus to rapidly reduce a temperature of the vibrator reached during a working operation. Also, a total of longer operating times are achievable before overheating of the vibrator threatens. The lubricant circuit through the excitation cell is no longer coupled to the operation of the excitation cell. Cooling of the lubricant used in the excitation cell can therefore be accelerated even during breaks by passing through the heat exchanger.

Zudem befindet sich das Schmiermittel für die Erregerzelle ausschließlich in der Rüttelvorrichtung und nicht - wie im Stand der Technik - zu einem großen Anteil im Baugerät oder Power-Pack. Auch ist die Menge des Schmiermittels in den Verbindungsschläuchen zwischen Rüttelvorrichtung und dem Baugerät oder dem Power-Pack nicht mehr notwendig. Vermischungen von Schmiermittel unterschiedlicher Qualität bzw. Zustand bei einem Tausch des Anbaugeräts an verschiedene Baumaschinen bzw. Power-Packs sind ausgeschlossen, da dessen Schmiermittelkreislauf nicht mit einem externen Gerät verbunden wird. Damit ist es auch ausgeschlossen, dass bei einem Wechsel des Schmiermittels, das neuwertige Schmiermittel durch altes, verunreinigtes Schmiermittel aus diversen Baumaschinen bzw. Power-Packs verunreinigt und damit in seinen Eigenschaften verschlechtert wird (nicht alle Schmiermittel sind miteinander mischbar!).In addition, the lubricant for the excitation cell is exclusively in the vibrator and not - as in the prior art - a large proportion in the construction equipment or power pack. Also, the amount of lubricant in the connecting tubes between vibrator and the construction equipment or the power pack is no longer necessary. Mixing of lubricant of different quality or state when replacing the attachment to various construction machines or power packs are excluded because the lubricant circuit is not connected to an external device. Thus, it is also excluded that when changing the lubricant, the new lubricant contaminated by old, contaminated lubricant from various construction machinery or power packs and thus deteriorated in its properties (not all lubricants are miscible with each other!).

Durch Vorsehen eines geschlossenen Schmiermittelkreislaufs in der Rüttelvorrichtung sind zudem deutlich geringere Mengen an Schmiermittel notwendig. Dies führt insgesamt zu einer geringeren Temperaturausdehnung und zu einer verminderten Verfälschung des Schmiermittelstandes in der Rüttelvorrichtung.By providing a closed lubricant circuit in the vibrator also significantly lower amounts of lubricant are necessary. Overall, this leads to a lower temperature expansion and to a reduced falsification of the lubricant level in the vibrator.

Da die Kühlung des Schmiermittelkreislaufs durch den Wärmetauscher direkt an der Rüttelvorrichtung vorgenommen wird, fällt zudem die Notwendigkeit der Kühlung des Schmiermittelkreislaufs am Baugerät weg. Dadurch können auch die Schlauchführungen zum Leiten des Schmiermittels von der Rüttelvorrichtung zu dem Baugerät und zurück sowie die entsprechenden Schlauchumlenkungen entfallen.Since the cooling of the lubricant circuit is made by the heat exchanger directly to the vibrator, also eliminates the need to cool the lubricant circuit on the construction equipment. As a result, the hose guides for guiding the lubricant from the vibrator device to the construction equipment and back as well as the corresponding hose deflections can be dispensed with.

Es ergibt sich zudem der Vorteil, dass bei einem Starten des Power-Packs oder des Baugeräts und bei einem gleichzeitigen Antreiben der an der Rüttelvorrichtung angeordneten Pumpe das Schmiermittel in der Erregerzelle bzw. die ganze Erregerzelle aufgewärmt wird und alle Lager und Schmierstellen schon bereits mit einem Starten der separaten Einheit mit Schmiermittel versorgt werden. So kann das durch die Erregerzelle fließende Schmiermittel bzw. die Erregerzelle an sich vorgewärmt werden und der besonders verschleißintensive Zustand eines Kaltstarts vermieden werden. Dadurch ergibt sich eine signifikant verlängerte Gesamtlebensleistung der Rüttelvorrichtung bzw. der Erregerzelle.It also has the advantage that when you start the power pack or the construction equipment and at the same time driving the arranged on the vibrator pump, the lubricant in the exciter cell or the whole exciter cell is warmed up and all bearings and lubrication points already with a Start the separate unit to be supplied with lubricant. Thus, the lubricant flowing through the excitation cell or the exciter cell can be preheated and the particularly wear-intensive state of a cold start can be avoided. This results in a significantly prolonged overall performance of the vibrator or the excitation cell.

Nach einer weiteren vorteilhaften Ausführungsform der Erfindung wird der zweite Kreislauf des Wärmetauschers mit einem Temperaturreguliermedium, insbesondere einem Schmiermittel oder einem HydraulikSchmiermittel, von einer zur Rüttelvorrichtung separaten Einheit versorgt. So ist beispielsweise denkbar, dass der zweite Kreislauf des Wärmetauschers mit einem Temperaturreguliermedium des Power-Packs oder eines die Rüttelvorrichtung tragenden Baugeräts gekoppelt ist.According to a further advantageous embodiment of the invention, the second circuit of the heat exchanger is supplied with a temperature regulating medium, in particular a lubricant or a hydraulic lubricant, from a unit separate from the vibrating device. For example, it is conceivable that the second circuit of the heat exchanger is coupled to a temperature-regulating medium of the power pack or a construction device carrying the vibrator device.

Vorzugsweise ist die separate Einheit, die den zweiten Kreislauf des Wärmetauschers mit dem Temperaturreguliermedium versorgt das Baugerät oder das Trägergerät, an dem die Rüttelvorrichtung anbringbar ist. Alternativ ist auch denkbar, dass die separate Einheit das Power-Pack ist.Preferably, the separate unit that supplies the second circuit of the heat exchanger with the temperature regulating medium is the construction equipment or the carrier device to which the vibrator device can be attached. Alternatively, it is also conceivable that the separate unit is the power pack.

Die Erfindung umfasst ferner ein Baugerät mit einer Rüttelvorrichtung, die eine der vorstehend aufgeführten Merkmalskombinationen umfasst. Zudem umfasst die Erfindung ein Baugerät mit einer Rüttelvorrichtung, die einen Wärmetauscher enthält, wobei der zweite Kreislauf des Wärmetauschers mit einem Temperaturreguliermedium, insbesondere einem HydraulikSchmiermittel, des Baugeräts versorgt wird.The invention further comprises a construction device with a vibrating device, which comprises one of the feature combinations listed above. In addition, the invention comprises a construction device with a vibrating device, which contains a heat exchanger, wherein the second circuit of the heat exchanger with a temperature regulating medium, in particular a hydraulic lubricant, the construction equipment is supplied.

Vorzugsweise wird die Pumpe der Rüttelvorrichtung über den Steuerdruck des Baugeräts angetrieben. Die Pumpe saugt dann das Schmiermittel aus der Erregerzelle an und fördert es durch einen Wärmetauscher wieder zurück zur Erregerzelle, in der alle Lager und Schmierstellen über Bohrungen mit Schmiermittel versorgt werden. Der zweite Kreislauf des Wärmetauschers wird dabei mit einem Temperaturreguliermedium, wie HydraulikSchmiermittel, vom Trägergerät versorgt. Dabei wird dann das Schmiermittel und in weiterer Folge auch die Erregerzelle an die Temperatur des Temperaturreguliermediums des Trägergeräts angepasst. In einer dem Baugerät oder dem Power-Pack nachfolgenden Startphase der Rüttelvorrichtung ist es demnach von Vorteil, dass die Rüttelvorrichtung bereits durch das im Baugerät zirkulierende Temperaturreguliermedium aufgeheizt werden kann. Dies gelingt, indem die Rüttelvorrichtung mit einem erwärmten Temperaturreguliermedium in den zweiten Kreislauf des Wärmetauschers einströmt und über diesen seine Wärme an den Schmiermittelkreislauf, der durch die Pumpe in der Rüttelvorrichtung betrieben wird, abgibt. Als Folge wird die Erregerzelle bzw. die gesamte Rüttelvorrichtung erwärmt, wodurch ein besonders schädliches Starten der Rüttelvorrichtung in einem kalten Zustand vermieden werden kann.Preferably, the pump of the vibrator is driven by the control pressure of the construction equipment. The pump then sucks in the lubricant from the excitation cell and returns it through a heat exchanger back to the excitation cell, where all bearings and lubrication points are supplied with lubricant via holes. The second circuit of the heat exchanger is supplied with a temperature regulating medium, such as hydraulic lubricant, from the carrier. In this case, the lubricant and subsequently also the exciter cell is then adapted to the temperature of the temperature regulating medium of the carrier device. In a start-up phase of the vibrating device following the construction device or the power pack, it is therefore advantageous that the vibrating device can already be heated by the temperature-regulating medium circulating in the construction device. This is achieved by the vibrator device flows with a heated Temperaturreguliermedium in the second circuit of the heat exchanger and through this its heat to the lubricant circuit, which is operated by the pump in the vibrator. As a result, the excitation cell or the entire vibrator is heated, whereby a particularly harmful starting the vibrator can be avoided in a cold state.

Auf der anderen Seite kann eine Überhitzung der Rüttelvorrichtung effektiv unterbunden werden, da auch in einer Betriebspause der Rüttelvorrichtung ein Zirkulieren des die Erregerzelle durchströmenden Schmiermittelkreislaufs aufrechterhalten werden kann. Es ist also möglich ohne ein Betreiben der Rüttelvorrichtung bzw. der Erregerzelle an sich den Schmiermittelkreislauf über den Wärmetauscher mit einem Temperaturreguliermedium des Trägergeräts abzukühlen und somit die Dauer von Arbeitspausen aufgrund einer drohenden Überhitzung zu minimieren.On the other hand, overheating of the vibrator can be effectively prevented, since even in an operating pause of the vibrator, a circulation of the exciter cell flowing through the lubricant circuit can be maintained. It is thus possible without operating the vibrator or the excitation cell per se, the lubricant circuit via the heat exchanger with a temperature regulating the carrier device to cool down and thus minimize the duration of breaks due to impending overheating.

Die vorliegende Erfindung wird darüber hinaus anhand eines Ausführungsbeispiels sowie einer Zeichnung näher beschrieben:

  • Es zeigt:
    Figur 1:
    eine Seitenansicht einer erfindungsgemäßen Rüttelvorrichtung.
The present invention will be further described with reference to an embodiment and a drawing:
  • It shows:
    FIG. 1:
    a side view of a vibrating device according to the invention.

Man erkennt die Rüttelvorrichtung 1, eine Erregerzelle 2 und an der Erregerzelle 2 angeordnete Anschlüsse 3, 4 für einen Schmiermittelablauf bzw. eine Schmiermittelzufuhr. Von dem Anschluss 3 für einen Schmiermittelablauf erstreckt sich eine Leitung zur Pumpe 5, die für eine Umwälzung bzw. ein Zirkulieren des Schmiermittelkreislaufs verantwortlich ist.One recognizes the vibrating device 1, an excitation cell 2 and arranged on the excitation cell 2 terminals 3, 4 for a lubricant outlet or a lubricant supply. From the connection 3 for a lubricant outlet, a line to the pump 5, which is responsible for a circulation or circulation of the lubricant circuit extends.

Von der Pumpe 5 verläuft der Schmiermittelkreislauf weiter zu einem Wärmetauscher 7, der mit einem Anschluss 4 für eine Schmiermittelzufuhr zur Erregerzelle 2 verbunden ist. Der Wärmetauscher 7 umfasst einen zweiten Kreislauf, der dazu geeignet ist, die Temperatur des Schmiermittelkreislaufs, der durch die Pumpe 5 und die Erregerzelle 2 fließt, zu beeinflussen. Der zweite Kreislauf wird durch die Versorgungsanschlüsse 8 von einer zur Rüttelvorrichtung externen Einheit gespeist und ist vorzugsweise mit dem Getriebeschmiermittelkreislauf des Baugeräts oder eines Power-Packs gekoppelt. Vorzugsweise entspricht der Getriebeschmiermittelkreislauf dem des Baugeräts, an dem die Rüttelvorrichtung angebracht ist. Alternativ sind die Versorgungsanschlüsse 8 auch mit einem Getriebeschmiermittelkreislauf eines Power-Packs verbindbar.From the pump 5, the lubricant circuit continues to a heat exchanger 7, which is connected to a connection 4 for a lubricant supply to the exciter cell 2. The heat exchanger 7 comprises a second circuit which is suitable for influencing the temperature of the lubricant circuit which flows through the pump 5 and the excitation cell 2. The second circuit is fed by the supply ports 8 from a unit external to the shaker device and is preferably coupled to the gear lubricant circuit of the equipment or power pack. The transmission lubricant circuit preferably corresponds to that of the construction equipment to which the vibrator device is attached. Alternatively, the supply connections 8 can also be connected to a transmission lubricant circuit of a power pack.

Mit dem Bezugszeichen 6 ist das Ziehjoch der Rüttelvorrichtung 1 gekennzeichnet, der einen Eingriffsabschnitt mit dem Baugerät bzw. mit einem Mäkler des Baugeräts darstellt. In der dargestellten Ausführungsform ist die Pumpe 5 an dem Ziehjoch 6 angeordnet.With the reference numeral 6, the drawing yoke of the vibrator 1 is characterized, which has an engagement portion with the construction equipment or with a leader of the Represents construction equipment. In the illustrated embodiment, the pump 5 is arranged on the draw yoke 6.

Die Pumpe 5 zum Umwälzen des Schmiermittelkreislaufs der Rüttelvorrichtung 1 ist über eine separate Leitung 9 antreibbar. Dadurch kann sichergestellt werden, dass eine Umwälzung des Schmiermittelkreislaufs in der Rüttelvorrichtung 1 unabhängig von deren Betrieb durchführbar ist. Typischerweise ist die separate Leitung 9 mit dem Steuerdruck des Baugeräts oder des Power-Packs verbunden. Durch die in der Fig. 1 wiedergegebene Konfiguration lassen sich sämtliche oben beschriebenen Vorteile erreichen.The pump 5 for circulating the lubricant circuit of the vibrator 1 can be driven via a separate line 9. This can ensure that a circulation of the lubricant circuit in the vibrator 1 is independent of their operation feasible. Typically, the separate conduit 9 is connected to the control pressure of the construction equipment or power pack. By in the Fig. 1 configuration can be achieved all the advantages described above.
