Maschine zur Ausführung von zwei parallelen Schnitten mit veränderbarem Abstand in Asphalt, Beton und dgl.Machine for making two parallel cuts with adjustable spacing in asphalt, concrete and the like.

Die Erfindung betrifft eine Maschine zur Ausführung von zwei parallelen Schnitten mit veränderbarem Abstand in Asphalt, Beton und dergleichen.The invention relates to a machine for performing two parallel cuts with variable spacing in asphalt, Concrete and the like.

Für Straßengrabungsarbeiten bei Asphalt- oder Betonstraßen wurden bisher Schneidvorrichtungen mit Abrieb- oder Diamantschneidscheiben verwendet, die mit einem einzigen Schnitt in voller Tiefe die geschlossene Deckenschicht durchschnitten, wobei der Greifer der Grabungsmaschine den von den beiden Schnitten begrenzten Deckenbereich entfernte und den restlichen Teil der Decke intakt ließ. Mit diesen herkömmlichen Schneidvorrichtungen mit einer einzigen Scheibe mußten die beiden Schnitte einzeln nacheinander ausgeführt werden, um einen Graben auszuheben.For road excavation work on asphalt or concrete roads, cutting devices with abrasive or diamond cutting discs have so far been used used, which cut through the closed ceiling layer in full depth with a single cut, the grapple of the digging machine removing the area of the ceiling bounded by the two cuts and the remainder Left part of the ceiling intact. With these conventional single disc cutters, the two cuts can be made one after the other to dig a trench.

Die Aufgabe der vorliegenden Erfindung besteht darin, diesen Nachteil zu vermeiden und eine Maschine zu schaffen, die zwei Schnitte in veränderbarem Abstand gleichzeitig ausführt, wobei der Abstand der beiden Schnitte voneinander der Breite desThe object of the present invention is to obviate this disadvantage and to provide a machine that has two Performs cuts at a variable distance at the same time, the distance between the two cuts being the width of the

gewünschten Grabens entspricht, so daß die Grabungs arbeit en se Meller durchführbar sind.corresponds to the desired trench, so that the excavation work en se Meller can be carried out.

Diese Aufgabe löst die Erfindung dadurch, daß mindestens eine angetriebene Welle senkrecht zur Schnittlängsrichtung vorhanden ist, an deren beiden Enden Schneidwerkzeuge anbringbar sind.This object is achieved by the invention in that at least one driven shaft is perpendicular to the longitudinal direction of the cut is present, at both ends of which cutting tools can be attached.

Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further refinements of the invention emerge from the subclaims.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigen:The invention is explained in more detail below with reference to an exemplary embodiment shown in the drawing. In the Drawing show:

Fig. 3 eine Seitenansicht zur Darstellung einiger Einzelheiten der Maschine.Fig. 3 is a side view showing some details of the machine.

Die in Fig. 1 und 2 dargestellte Maschine umfaßt einen Motor 1 mit einer Riemen-Antriebs-Übertragung 2 vom Motor auf die Welle 3. Am äußeren Ende der Welle 3 sind von Schutzvorrichtungen 5 bzw. 51 abgedeckte Schneidscheiben 4 bzw. 4' anbringbar.The in Fig. 1 and 2 illustrated machine comprises an engine 1 with a belt-drive transmission 2 from the engine 3 to the shaft at the outer end of the shaft 3 are protective devices 5 and 5 1 covered cutting discs 4 and 4 'mountable .

Die Antriebs-Übertragung von der Welle 3 auf die Welle 7 findet über Riemen 6 oder andere geeignete Mittel statt. An den äußeren Enden der Welle 7 sind Schneidscheiben 8 bzw. 81 befestigbar, die von Schutzvorrichtungen 9» 9r abgedeckt werden. Zum Vorschub der Maschine treibt der Antriebsmotor 1 über Riemen 10 oder ein anderes geeignetes Mittel ein stufenlos veränderbares Getriebe 11 an, das über die Kette 12 mit der Rille für die Hinterräder 14, 14' verbunden ist. Die Räder 14 und 14' sind fest mit der Welle 13 verbunden. Die Maschine weist zwei Vorderräder 15, 15' auf, die fest auf der Welle 16 montiertThe drive transmission from the shaft 3 to the shaft 7 takes place via belt 6 or other suitable means. Cutting disks 8 and 8 1 can be attached to the outer ends of the shaft 7 and are covered by protective devices 9 »9 r. To advance the machine, the drive motor 1 drives a continuously variable transmission 11 via a belt 10 or some other suitable means, which is connected via the chain 12 to the groove for the rear wheels 14, 14 '. The wheels 14 and 14 'are firmly connected to the shaft 13. The machine has two front wheels 15, 15 'which are fixedly mounted on the shaft 16

sind. Die Einstellung der Schnittiefe der Schneidscheiben geschieht durch ein kleines Stellrad 17» das über zwei Untersetzungsgetriebe 18, die Stellschraube 19» die Schraubenmutter 20 (!"ig. 1 und 3) mit einer Gelenkverbindung 21 verbunden ist. Durch Hebel 22 und 24, die beweglich am Drehpunkt 23 befestigt sind, werden die Vorderräder 15» 15' gehoben und gesenkt, wodurch die Schnitttiefe der Schneidscheiben reguliert wird. Bei der stärksten Neigung der Grundplatte 25» die die gesamten Maschinenteile trägt, befindet sich das stirnseitige, mittige Lenkrad 26 infolge seiner besonderen, höhenmäßigen Anordnung auf derselben Linie mit den Vorderrädern 15» 15'j wobei die Hinterräder 13» 13' gegenüber der Erdoberfläche eingezogen sind, so daß die Maschine an der Baustelle leicht bewegbar ist, wobei die drei abstützenden Eäder fest auf ihren Wellen angeordnet sind.are. Adjusting the cutting depth of the cutting discs is done by a small adjusting wheel 17 »that has two reduction gears 18, the adjusting screw 19 and the screw nut 20 (! "Figs. 1 and 3) are connected to an articulated connection 21 is. By levers 22 and 24, which are movably attached to the pivot point 23, the front wheels 15 »15 'are raised and lowered, which regulates the cutting depth of the cutting discs. At the greatest inclination of the base plate 25 »die carries the entire machine parts, the front, central steering wheel 26 is due to its special, height-related Arrangement on the same line with the front wheels 15 »15'j with the rear wheels 13» 13 'facing the surface of the earth are retracted so that the machine can be easily moved at the construction site, with the three supporting wheels firmly on their Waves are arranged.

Der Motor 1 treibt über eine Riemen-Übertragung 27 auch eine Pumpe 28, die für den beschleunigten Umlauf von Wasser vorgesehen ist, das durch die biegsamen Leitungen 28' zu den Schutzvorrichtungen und den Schneidscheiben oder Messern zur Kühlung zugeleitet wird, an.The motor 1 also drives a belt transmission 27 Pump 28 designed to accelerate the circulation of water through flexible pipes 28 'to the protection devices and fed to the cutting disks or knives for cooling.

Zum Starten des Motors 1 der Maschine ist außerdem eine nicht dargestellte Akkumulatorbatterie mit erforderlichem Anlasser und dergl. vorgesehen.To start the engine 1 of the machine, there is also a non-illustrated accumulator battery with a required starter and the like. Provided.

Um einen Doppel-Schnitt von relativ geringem Abstand durchzuführen, werden die zwei Schneidscheiben 8, 8' auf der Welle 7 verwendet, während auf der Welle 3 keine Scheiben angeordnet sind. Die Schutzvorrichtungen können dabei auf der Welle 3 angebracht bleiben oder auch weggelassen werden.To make a double cut from a relatively short distance, the two cutting disks 8, 8 'are used on the shaft 7, while no disks are arranged on the shaft 3 are. The protective devices can remain attached to the shaft 3 or can be omitted.
