Description

Die Erfindung betrifft eine Schlitzwandfräse mit mindestens zwei Fräsrädern oder Fräsradpaaren, deren Drehachsen zueinander versetzt sind.The invention relates to a trench cutter with at least two cutting wheels or pairs of cutting wheels whose axes of rotation to each other are offset.

Aus der DE 34 24 999 C2 gehen zwei unterschiedliche Arten von Schlitzwandfräsen hervor. So gibt es Schlitzwandfräsen mit einem Fräsrad oder einem Fräsradpaar mit zwei Fräsrädern, welche eine gemeinsame Drehachse besitzen. Ein einzelnes Fräsradpaar wird über einen gemeinsamen Antrieb in Rotation versetzt, wie in den Fig. 2 und 3 der DE 34 24 999 C2 dargestellt ist. Eine entsprechende Getriebeanordnung zum Antrieb eines einzelnen Fräsradpaares ist auch aus der DE 196 52 022 A1 bekannt.From DE 34 24 999 C2 go two different types of Slit wall milling out. So there are trench wall cutters with one Milling wheel or a pair of cutting wheels with two cutting wheels, which have a common axis of rotation. A single pair of cutting wheels is rotated by a common drive, such as is shown in Figs. 2 and 3 of DE 34 24 999 C2. A corresponding gear arrangement for driving a single Milling wheel pair is also known from DE 196 52 022 A1.

Eine gattungsgemäße Schlitzwandfräse mit zwei Fräsradpaaren, welche zueinander quer zu den Drehachsen versetzt sind, ist in Fig. 1 der DE 34 24 999 C2 dargestellt. Die beiden Fräsradpaare werden jeweils von einem separaten Antriebsmotor über eine entsprechende Getriebeanordnung in Rotation versetzt.A generic trench wall cutter with two pairs of cutting wheels, which are offset from each other transversely to the axes of rotation is in Fig. 1 DE 34 24 999 C2 shown. The two pairs of cutting wheels each of a separate drive motor via a corresponding gear assembly rotated.

Der Erfindung liegt die Aufgabe zugrunde, eine Schlitzwandfräse anzugeben, welche bei einem einfachen und kompakten Aufbau einen zuverlässigen Fräsbetrieb sicherstellt.The invention has for its object to provide a trench cutter, which ensures a reliable milling operation in a simple and compact structure.

Die Aufgabe wird erfindungsgemäß durch eine Schlitzwandfräse mit den Merkmalen des Anspruchs 1 gelöst. Bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen angegeben.The object is achieved by a trench cutter solved with the features of claim 1. Preferred embodiments are indicated in the dependent claims.

Die erfindungsgemäße Schlitzwandfräse ist dadurch gekennzeichnet, dass ein einzelner Antriebsmotor vorgesehen ist, welcher über eine Getriebeanordnung die mindestens zwei Fräsräder oder Fräsradpaare gemeinsam antreibt.The trench wall cutter according to the invention is characterized that a single drive motor is provided, which via a gear arrangement, the at least two cutting wheels or Driving pairs of cutting wheels together.

Durch die Erfindung wird nicht nur der Aufwand für den Antrieb und das Getriebe der Schlitzwandfräse praktisch halbiert, sondern ein gemeinsamer Antrieb und eine gemeinsame Getriebeanordnung ermöglichen auch eine Zwangssynchronisation der Fräsräder. Dies erlaubt, die quer zur Drehachse nebeneinander versetzt angeordneten Fräsräder dichter nebeneinander anzuordnen. Es ergibt sich eine besonders kompakte Schlitzwandfräse mit guter Abtragsleistung, bei welcher auch die Gefahr eines Steckenbleibens innerhalb des Schlitzes deutlich vermindert ist.The invention is not only the effort for the drive and the gearbox of the trench wall cutter practically halved, but a common drive and a common gear arrangement also allow forced synchronization of the cutting wheels. This allows the side by side offset transversely to the axis of rotation arrange arranged cutting wheels closer together. This results in a particularly compact diaphragm wall cutter Good removal performance, which also the risk of getting stuck within the slot is significantly reduced.

Eine bevorzugte Ausführungsform der Erfindung besteht darin, dass die Getriebeanordnung ein Sonnenrad aufweist, welches im Wesentlichen mittig zwischen den zwei zueinander versetzt angeordneten Drehachsen angeordnet ist. Es ergibt sich so eine symmetrische Drehmomenteinleitung, was eine besonders gleichmäßige Drehmomentverteilung ermöglicht.A preferred embodiment of the invention is that the gear arrangement has a sun gear, which in the Substantially centered between the two offset from each other Rotary axes is arranged. It results in such a symmetrical torque introduction, which is a particularly uniform Torque distribution allows.

Eine besondere kompakte Getriebeanordnung wird erfindungsgemäß dadurch erreicht, dass die zwei Fräsräder oder Fräsradpaare jeweils einen Antriebsstrang aufweisen, welche von dem Sonnenrad angetrieben werden.A special compact gear arrangement is inventively achieved in that the two cutting wheels or Fräsradpaare each having a drive train, which of the sun gear are driven.

Eine besonders gute Drehmomentverteilung bei einem kompakten Aufbau wird nach der Erfindung dadurch erreicht, dass die Antriebsstränge in einem spitzen Winkel zur Achse des Sonnenrades angeordnet sind. Die Antriebsstränge bilden dabei mit dem Sonnenrad eine Anordnung in Form eines umgedrehten Y, wobei die Antriebsstränge oberhalb der Drehachsen der Fräsräder angeordnet und nach oben gerichtet sind. Der spitze Winkel beträgt vorzugsweise zwischen 15° und 60°, insbesondere 45°.A particularly good torque distribution in a compact Structure is achieved according to the invention in that the drive trains at an acute angle to the axis of the sun gear are arranged. The drive trains form with the Sun gear an arrangement in the form of an inverted Y, wherein the drive trains arranged above the axes of rotation of the cutting wheels and are directed upwards. The acute angle is preferably between 15 ° and 60 °, in particular 45 °.

Für eine gute Lastverteilung ist es dabei besonders bevorzugt, dass die Antriebsstränge etwa in einem rechten Winkel zueinander angeordnet sind. For a good load distribution, it is particularly preferred that the drive trains are approximately at a right angle to each other are arranged.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass die Antriebsstränge jeweils mindestens ein Übersetzungsgetriebe aufweisen. Unter Übersetzungsgetriebe wird selbstverständlich auch eine Untersetzung verstanden. Es kann so eine gewünschte Drehmomentwandlung unmittelbar an den Fräsrädern erfolgen. Darüber hinaus weisen die Antriebsstränge bei der Anordnung von Fräsradpaaren jeweils auch ein Verteilungsgetriebe auf, welches das Drehmoment des Antriebsstrangs zu gleichen Teilen auf die Fräsräder entlang der gleichen Drehachse verteilt.According to a further embodiment of the invention is provided that the drive trains each have at least one transmission gear exhibit. Under transmission gear is of course understood as a reduction. It can such a desired torque conversion directly to the cutting wheels respectively. In addition, the drive trains at the arrangement of Fräsradpaaren each also a distribution gear on which the torque of the powertrain to equal parts on the cutting wheels along the same axis of rotation distributed.

Weiterhin ist es nach der Erfindung von Vorteil, dass an den Fräsrädern oder Fräsradpaaren radial vorstehende Fräszähne vorgesehen sind, welche in Betrieb ineinander greifend angeordnet sind. Aufgrund der mit der Erfindung erreichbaren Zwangssynchronisation der nebeneinander liegenden Fräsräder können diese so eng beieinander angeordnet werden, dass die Fräszähne gefahrlos miteinander kämmen. Auf diese Weise kann über den gesamten Fräsquerschnitt eine gleichmäßig hohe Abtragsleistung erreicht werden.Furthermore, it is advantageous according to the invention that the Milling wheels or pairs of cutting wheels radially projecting cutting teeth are provided, which interengaging arranged in operation are. Due to the achievable with the invention Forced synchronization of adjacent cutting wheels these can be arranged so close together that the Combine cutting teeth safely with each other. This way you can a consistently high removal rate over the entire milling cross section be achieved.

Eine besonders gute und wartungsfreundliche Ausgestaltung der Erfindung ist dadurch gegeben, dass der Antriebsmotor und die Getriebeanordnung in einem Fräsgehäuse angeordnet sind.A particularly good and maintenance-friendly design of the Invention is given by the fact that the drive motor and the Gear arrangement are arranged in a milling housing.

Dabei ist es besonders bevorzugt, dass die Schlitzwandfräse an einem teleskopierbaren Gestänge befestigt ist und dass die Dicke des Fräsengehäuses in Richtung der Drehachsen kleiner oder gleich dem maximalen Durchmesser des teleskopierbaren Gestänges ist. Während bei herkömmlichen Fräsen üblicherweise ein sehr großer Fräsrahmen gegeben ist, welcher zur Führung der Schlitzwandfräse im Schlitz notwendig ist, kann die erfindungsgemäße kompakte Schlitzwandfräse durch ein teleskopierbares Gestänge geführt werden. Durch den erfindungsgemäßen kompakten Aufbau des Fräsengehäuses, welches nicht über den maximalen Durchmesser des teleskopierbaren Gestänges in Richtung der Drehachsen hinausragt, wird die Gefahr eines Verklemmens der Schlitzwandfräse im Schlitz drastisch vermindert. It is particularly preferred that the trench wall cutter on a telescopic rod is attached and that the thickness the milling housing in the direction of the axes of rotation smaller or equal to the maximum diameter of the telescopic linkage is. While in conventional milling usually a given very large cutting frame, which is used to guide the Trench wall cutter in the slot is necessary, the inventive Compact trench wall cutter through a telescopic Linkage be led. By the compact invention Structure of the milling housing, which does not exceed the maximum Diameter of the telescopic linkage in the direction the axes of rotation protrudes, the risk of jamming the trench wall cutter in the slot is drastically reduced.

Nach einer anderen bevorzugten Ausführungsform ist es erfindungsgemäß vorgesehen, dass zwischen dem Antriebsmotor und dem Sonnenrad eine Hauptantriebswelle angeordnet ist. Die Hauptantriebswelle kann dabei an ihren beiden Enden jeweils Bogenverzahnungen aufweisen, welche in entsprechenden Verzahnungshülsen des Äntriebsmotors bzw. des Sonnenrads kämmend angeordnet sind. Eine derartige Anordnung erlaubt eine Kompensation von Stößen sowie Verwindungen zwischen dem Antriebsmotor und dem Sonnenrad, so dass eine besonders langlebige Getriebeanordnung geschaffen wird.According to another preferred embodiment, it is according to the invention provided that between the drive motor and the Sun gear is arranged a main drive shaft. The main drive shaft can each be at both ends of each curved teeth having, which in corresponding toothed sleeves the drive motor or the sun gear arranged in mesh are. Such an arrangement allows a compensation of Bumps and torsions between the drive motor and the Sun gear, giving a particularly durable gear assembly is created.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispieles näher beschrieben, welches stark schematisiert in der einzigen Zeichnungsfigur dargestellt ist.The invention will be described below with reference to an embodiment described in more detail, which is highly schematic in the single drawing figure is shown.

Eine erfindungsgemäße Schlitzwandfräse 10 gemäß der Figur zeigt zwei Fräsräder 12, 14, an deren Außenumfang eine Vielzahl von Fräszähnen 20 angeordnet sind. Die Fräsräder 12, 13 gehören jeweils zu einem Fräsradpaar, wobei das hintere Fräsrad nicht dargestellt ist. Das linksseitige Fräsrad 12 des einen Fräsradpaares dreht sich um eine erste Drehachse 16, während das rechtseitige Fräsrad 14 des anderen Fräsradpaares sich um eine zweite Drehachse 18 dreht. Die beiden Drehachsen 16, 18 sind in einer Querrichtung zueinander um einen vorgegebenen Abstand versetzt. Das linksseitige Fräsrad 12 ist im Uhrzeigersinn angetrieben, während das rechtseitige Fräsrad 14 entgegen des Uhrzeigersinns angetrieben ist.A trench wall cutter 10 according to the invention according to the figure shows two cutting wheels 12, 14, at the outer periphery of a plurality of cutting teeth 20 are arranged. The cutting wheels 12, 13 each belong to a pair of cutting wheels, the rear cutting wheel not shown. The left-side cutting wheel 12 of the one Milling wheel pair rotates about a first axis of rotation 16, while the right-side cutting wheel 14 of the other pair of cutting wheels rotates about a second axis of rotation 18. The two axes of rotation 16, 18 are in a transverse direction to each other by a predetermined Distance offset. The left-side cutting wheel 12 is in The right-hand cutting wheel 14 is driven in the clockwise direction is driven counterclockwise.

Von einem oberhalb der Drehachsen 16, 18 angeordneten, nicht dargestellten gemeinsamen Antriebsmotor wird das Antriebsdrehmoment über eine Getriebeanordnung 30 auf die Fräsräder 12, 14 bzw. deren Fräsradpaare übertragen. Zum Antriebsmotor wird das Drehmoment über eine teilweise dargestellte Hauptantriebswelle 36 auf ein Sonnenrad 32 übertragen. Die Hauptantriebswelle 36 weist hierzu an ihrem unteren Ende eine Bogenverzahnung 37 auf, welche in einer entsprechenden Verzahnungshülse am oberen Ende des Sonnenrades 32 angeordnet ist. Das Sonnenrad 32 weist eine Achse 33 auf, welche etwa senkrecht zu den Drehachsen 16, 18 der Fräsräder 12, 14 gerichtet und mittig hierzu angeordnet ist.From one above the axes of rotation 16, 18 arranged not shown common drive motor is the drive torque via a gear arrangement 30 to the cutting wheels 12, 14th or their Fräsradpaare transmitted. The drive motor is the Torque over a partially shown main drive shaft 36 transmitted to a sun gear 32. The main drive shaft 36 has for this purpose at its lower end a curved toothing 37th on, which in a corresponding toothed sleeve at the top End of the sun gear 32 is arranged. The sun gear 32 has an axis 33 which is approximately perpendicular to the axes of rotation 16, 18 of the cutting wheels 12, 14 directed and arranged centrally thereto is.

Von einer Ritzelverzahnung des Sonnenrades 32 wird das Drehmoment in kämmender Verbindung über Tellerzahnräder 42, 52 auf die Antriebesstränge 40, 50 für die Fräsräder 12, 14 bzw. deren Fräsradpaare übertragen. Die Antriebsstränge 40, 50 weisen jeweils nicht dargestellte Übersetzungsgetriebe auf, welche die Drehzahl des Sonnenrades 32 untersetzen und so das Drehmoment für die Fräsräder 12, 14 auf einen gewünschten Wert erhöhen. Durch das Abgreifen des Drehmoments an dem Sonnenrad 32 durch die Tellerzahnräder 42, 52 an gegenüberliegenden Stellen kann bei ansonsten gleicher Ausgestaltung der Antriebsstränge 40, 50 eine gleichmäßige Drehmomentverteilung bei entgegengesetzter Drehrichtung in einfacher Weise erreicht werden.From a pinion gear of the sun gear 32, the torque in meshing connection via ring gears 42, 52 the drive trains 40, 50 for the cutting wheels 12, 14 and their Transfer cutting wheel pairs. The drive trains 40, 50 have in each case not shown transmission gear, which reduce the speed of the sun gear 32 and so the torque for the cutting wheels 12, 14 increase to a desired value. By picking up the torque on the sun gear 32nd through the plate gears 42, 52 at opposite locations can with otherwise the same configuration of the drive trains 40, 50 a uniform torque distribution at opposite Direction of rotation can be achieved in a simple manner.

Die Achsen der Antriebsstränge 40, 50 sind etwa rechtwinklig zueinander angeordnet und bilden mit der Achse 33 des Sonnenrades 32 eine auf dem Kopf stehende Y-Anordnung.The axes of the drive trains 40, 50 are approximately at right angles arranged to each other and form with the axis 33 of the sun gear 32 an upside down Y-arrangement.
