Von aus dem Stand der Technik bekannten Arbeitsmaschinen ist es bekannt, Augstäbe vorzusehen, die zum Heben von beispielsweise einem Gußballast oder einer Drehbühne der Arbeitsmaschine dienen können. Die Augstäbe können dabei Bestandteil des Gußballastes sein. Auch ist es bekannt, eine Hebetraverse beispielsweise unter einer entsprechenden Drehbühne zu verwenden, um den Gußballast und/oder die Arbeitsmaschine und/oder die Drehbühne entsprechend manipulieren bzw. anheben zu können.From known from the prior art machines, it is known to provide eye rods, which can serve for lifting, for example, a Gußballast or a revolving stage of the machine. The eye rods can be part of the cast ballast. It is also known to use a lifting traverse, for example under a corresponding revolving stage, in order to be able to manipulate or lift the cast ballast and / or the working machine and / or the revolving stage accordingly.
Nachteilig an den aus dem Stand der Technik bekannten Vorrichtungen ist, dass Gußballaste keine definierte Sicherheit für an ihnen vorgesehene Hebepunkte bzw.A disadvantage of the known from the prior art devices is that Gußballaste no defined security for intended for them lifting points or
Gewinde aufweisen, da sich bei Gußballasten auftretende Lunker nachteilig und in nicht vorhersehbarer oder einfach feststellbarer Weise auf die Stabilität des Gußballasts auswirken können.Have thread, as occurring in Gußballasten blowholes can adversely affect the stability of the Gußballasts disadvantageous and unpredictable or easily ascertainable manner.
Bei Schweißballasten ist es fernerhin bekannt, eine aufwendige Tragstruktur in das Ballastgewicht zu integrieren bzw. mit dem Ballastgewicht zu integrieren. Dabei können an dem Ballast beispielsweise zwei Hebepunkte vorgesehen werden, die beispielsweise in Kombination mit zwei weiteren Hebepunkten z.B. am Monausleger zum Anheben der gesamten Arbeitsmaschine bzw. des Ballasts genutzt werden können.In welding ballasts, it is also known to integrate a complex support structure in the ballast or integrate with the ballast weight. In this case, two lifting points can be provided on the ballast, for example, in combination with two other lifting points, e.g. can be used on the Monausleger for lifting the entire machine or the ballast.
Vor diesem Hintergrund ist es Aufgabe der Erfindung, eine Arbeitsmaschine bereitzustellen, die ein einfacheres und/oder sichereres Anheben von deren Ballastgewicht bzw. von der Arbeitsmaschine selbst oder Teilen davon ermöglicht.Against this background, it is an object of the invention to provide a working machine that allows a simpler and / or safer lifting of their ballast weight or of the work machine itself or parts thereof.
Diese Aufgabe wird erfindungsgemäß durch eine Arbeitsmaschine mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausbildungen sind Gegenstand der Unteransprüche. Demnach ist eine Arbeitsmaschine vorgesehen, bei der das Ballastgewicht und die Ballastauflage je wenigstens zwei Durchführungen umfassen, die miteinander fluchten.This object is achieved by a work machine with the features of
Die Ballastauflage kann beispielsweise als Metallträger ausgebildet sein, der Teil des Gefüges der Arbeitsmaschine und insbesondere beispielsweise eines Oberwagens der Arbeitsmaschine ist. Bei dem Ballastgewicht kann es sich um einen oder mehrere Körper handeln, die beispielsweise aus einem Metall oder aus Beton gefertigt sind und die je nach benötigtem Ballastgewicht ggf. in unterschiedlicher Anzahl auf der Ballastauflage ablegbar sind.The ballast support may be formed, for example, as a metal carrier, which is part of the structure of the working machine and in particular, for example, a superstructure of the working machine. The ballast weight may be one or more bodies which are made, for example, of a metal or of concrete and, depending on the required ballast weight, may optionally be deposited in different numbers on the ballast support.
Das wenigstens eine Ballastgewicht und die wenigstens eine Ballastauflage können jeweils zwei Durchführungen umfassen, die in wenigstens einer Stellung von Ballastgewicht und Ballastauflage miteinander fluchten können. Die Durchführungen ermöglichen es, ein Verbindungsmittel durch diese hindurch zu führen und mit Strukturen beispielsweise der Ballastauflagen, die sich unterhalb des Ballastgewichts befinden können, zu verbinden. Hierdurch kann ein Bereich zum Koppeln von Kopplungsmitteln mit der Arbeitsmaschine genutzt werden, welcher zum einen ein statisch vorteilhafter Bereich zum Anheben des Ballastgewichts und/oder der Arbeitsmaschine ist und zum anderen die Notwendigkeit sonstiger Einrichtungen zum Anheben, wie Augstäbe oder Hebetraversen, entfallen lässt.The at least one ballast weight and the at least one ballast support can each comprise two bushings which can be aligned with one another in at least one position of ballast weight and ballast support. The bushings make it possible to guide a connecting means therethrough and with Structures, for example, the ballast pads, which may be located below the ballast weight to connect. This makes it possible to use an area for coupling coupling means with the working machine, which on the one hand is a statically advantageous area for lifting the ballast weight and / or the working machine and on the other eliminates the need for other lifting devices, such as eye bars or lifting traverses.
In einer Ausführung, in der die Ballastauflage Teil einer Drehbühne der Arbeitsmaschine ist, können die einzigen lasttragenden Komponenten der Vorrichtung beim Anheben der Arbeitsmaschine und/oder des Ballastgewichts die Drehbühne selbst und die durch die Durchführungen geführten Verbindungsmittel sein. Das Ballastgewicht muss daher nicht zum Tragen zusätzlicher Gewichte ausgelegt werden sondern es genügt, dieses nur zum Tragen von dessen Eigengewicht auszulegen. Hierdurch wird ein vorteilhaft einfacher Aufbau des Ballastgewichtes bzw. der Ballastgewichte ermöglicht, was eine kostengünstigere Herstellung ermöglicht.In an embodiment in which the ballast pad is part of a turntable of the work machine, the only load bearing components of the apparatus when lifting the work machine and / or the ballast weight, the turntable itself and the guided through the bushings connecting means. The ballast weight must therefore not be designed to carry additional weights but it is sufficient to interpret this only to carry its own weight. As a result, an advantageously simple construction of the ballast weight or the ballast weights is possible, allowing a more cost-effective production.
Weiterhin ermöglicht die erfindungsgemäße Ausgestaltung der Arbeitsmaschine einen modularen Aufbau der Vorrichtung, wobei insbesondere Kopplungsmittel bzw. Verbindungsmittel optional mit der Arbeitsmaschine bereitgestellt werden können bzw. gegebenenfalls nachträglich nachgerüstet werden können.Furthermore, the inventive design of the work machine allows a modular design of the device, in particular coupling means or connecting means can optionally be provided with the working machine or optionally retrofitted.
Die Kopplungsmittel können fernerhin einfach montiert und demontiert werden, was auch im Baustelleneinsatz der Arbeitsmaschine erfolgen kann und nicht wie aus dem Stand der Technik bekannt werkseitig bzw. während der Herstellung der Arbeitsmaschine erfolgen muss. Die Montage und Demontage des Kopplungsmittels kann somit auch nachträglich an einer bereits bestehenden Arbeitsmaschine erfolgen.The coupling means can furthermore be easily assembled and disassembled, which can also take place in the construction site of the working machine and not known from the prior art factory or during the manufacture of the machine must be done. The assembly and disassembly of the coupling means can thus also be done later on an existing machine.
Ein weiterer Vorteil der erfindungsgemäßen Arbeitsmaschine besteht darin, dass auch bereits bestehende, nicht erfindungsgemäße Arbeitsmaschinen bzw. Drehbühnen oder Oberwagen einfach, beispielsweise durch lediglich gering Modifizierungen, nachträglich umgerüstet werden können, so dass eine erfindungsgemäße Arbeitsmaschine bereitgestellt werden kann.Another advantage of the working machine according to the invention is that even existing, non-inventive machines or revolving platforms or superstructure easy, for example, by only minor modifications, can be retrofitted, so that a work machine according to the invention can be provided.
Fernerhin bietet eine erfindungsgemäße Arbeitsmaschine den Vorteil, dass auch demontierter Ballast unter Nutzung der an dem Ballastgewicht und/oder der Ballastauflage vorgesehenen Durchführungen einfach mittels entsprechender Kopplungsmittel angehoben werden kann.Furthermore, a working machine according to the invention offers the advantage that even dismounted ballast can be easily lifted by means of appropriate coupling means using the bushings provided on the ballast weight and / or the ballast support.
Die Durchführungen in der Ballastauflage und/oder in dem Ballastgewicht können insbesondere in einer betriebsbereiten Konfiguration, beispielsweise mit aufliegendem Ballast, in einer vertikalen oder in einer von der vertikalen abweichenden Richtung angeordnet sein. Hierdurch wird das Einführen von Kopplungsmitteln in die Durchführungen vereinfacht. Auch wird auf diese Weise sichergestellt, dass die in den Durchführungen verlaufenden Kopplungsmittel im Wesentlichen in Kraftrichtung ausgerichtet sind, wodurch das Risiko von Beschädigungen der Kopplungsmittel verringert werden kann. Die Kraftrichtung bezeichnet hierbei die Richtung, in die die durch die Kopplungsmittel übertragene Kraft wirkt.The feedthroughs in the ballast support and / or in the ballast weight can in particular be arranged in a ready-to-use configuration, for example with overlying ballast, in a vertical or in a direction deviating from the vertical direction. This simplifies the introduction of coupling means into the bushings. It is also ensured in this way that the coupling means running in the bushings are aligned substantially in the direction of the force, whereby the risk of damage to the coupling means can be reduced. The force direction here denotes the direction in which the force transmitted by the coupling means acts.

Damit ist gemeint, dass sich die Arbeitsmaschine in einem Zustand befindet, in dem sie zum Durchführen von Arbeiten bereit, d.h. unter anderem hinreichend ausballastiert ist. Zum Anheben der Arbeitsmaschine bzw. des Ballasts ist es somit nicht erforderlich, diese umständlich in einen anderen Zustand zu überführen. Die Arbeitsmaschine bzw. der Ballast kann so besonders einfach und schnell angehoben werden.In a preferred embodiment of the invention, it is conceivable that the bushings are aligned with each other in a state of the work machine by the work machine is at least partially ballasted by the ballast weight.

Die weiteren genannten Möglichkeiten stellen Ausführungen dar, bei denen auf besonders einfache Weise entsprechende Durchführungen bereitgestellt werden können.In a further preferred embodiment, it is conceivable that at least one of the passages is formed as a bore, as a cast channel, as inserted hollow profile and / or as a recessed channel and / or that at least one of the bushings at least one bore, at least one casting channel, at least one inserted hollow profile and / or at least one recessed channel comprises.
