Description

Die Erfindung betrifft einen Fräskopf zum Längs- oder Querschneiden von Böden nach dem Oberbegriff des Anspruchs 1 bzw. 6.The invention relates to a milling head for the longitudinal or transverse cutting of 6 soils according to the preamble of claim 1.

Bei derartigen Fräsköpfen ist es problematisch, in härtere Böden, etwa Beton, Asphalt, Felsböden od.dgl., einzudringen, da der Fräskopf ausschlägt und hin und her tanzt. Diese Bewegungen sind von dem jeweiligen Baggerführer nur schwierig, wenn überhaupt unter Kontrolle zu halten.With milling heads of this type, it is problematic to work in harder soils, for example Concrete, asphalt, rocky floors or the like to penetrate because the milling head deflects and dances back and forth. These movements are from the respective excavator operator only difficult if at all to keep under control.

Aufgabe der Erfindung ist es daher, einen Fräskopf nach dem Oberbegriff des Anspruchs 1 bzw. 6 zu schaffen, der sich auch bei härteren Böden problemlos einsetzen läßt.The object of the invention is therefore a milling head according to the preamble of claim 1 or 6 to create, which is easy even on harder soils can be used.

Diese Aufgabe wird entsprechend dem kennzeichnenden Teil des Anspruchs 1 bzw. 6 gelöst.This task is according to the characterizing part of the claim 1 or 6 solved.

Weitere Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung und den Unteransprüchen zu entnehmen. Further refinements of the invention are as follows Description and the dependent claims.

Die Erfindung wird nachstehend anhand eines in den beigefügten Abbildungen schematisiert dargestellten Ausführungsbeispiels näher erläutert.The invention is illustrated below with the aid of one of the following Illustrated schematically illustrated embodiment.

Fig. 1 zeigt einen an einem Baggerarm montierten Fräskopf in Seitenansicht.Fig. 1 shows a milling head mounted on an excavator arm in side view.

Fig. 2 zeigt eine Draufsicht auf eine Trägerkonsole für den Fräskopf von Fig. 1.FIG. 2 shows a top view of a carrier console for the milling head from FIG. 1.

Fig. 3 zeigt schematisiert eine weitere Ausführungsform eines Fräskopfes in Seitenansicht.3 schematically shows a further embodiment of a milling head in FIG Side view.

Der in Fig. 1 und 2 dargestellte Fräskopf umfaßt ein beispielsweise hydraulisch arbeitendes Antriebsaggregat 1, das über nicht dargestellte flexible Leitungen versorgt wird und ein um seine Achse rotierendes Fräswerkzeug 2 trägt, das auf einer Spindel des Antriebsaggregats 1 angeordnet ist. Das Fräswerkzeug 2 besitzt eine Vielzahl von auf einem Mantel 3 angeordneten Fräsmeißeln 4 sowie eine ebenfalls auf dem Mantel 3 angeordnete Schnecke 5 zum Transportieren von gefrästem Material.The milling head shown in FIGS. 1 and 2 includes, for example hydraulically operating drive unit 1, which is flexible, not shown Lines is supplied and carries a milling tool 2 rotating about its axis, which is arranged on a spindle of the drive unit 1. The milling tool 2 has a large number of milling cutters 4 and 3 arranged on a casing 3 a screw 5 also arranged on the casing 3 for transporting milled material.

Das Antriebsaggregat 1 ist auf der dem Fräswerkzeug 2 abgekehrten Seite mit einer Adapterplatte 6 versehen, mit der der Fräskopf an einem Baggerarm 7 befestigbar ist.The drive unit 1 is on the side facing away from the milling tool 2 provided with an adapter plate 6 with which the milling head on an excavator arm 7 is attachable.

An dem Antriebsaggregat 1 ist eine Trägerkonsole 8 befestigt, insbesondere angeschraubt. Die Trägerkonsole 8 ist U-förmig und umfaßt gemäß dem dargestellten Ausführungsbeispiel zwei zueinander beabstandete, parallele Platten 9, 10, die an dem Antriebsaggregat 1 angeschraubt und durch eine vertikale Platte 11 miteinander verbunden sind. Die Trägerkonsole 8 kann insoweit einstückig sein oder aus mehreren miteinander verschweißten Teilen bestehen. Zusätzlich können ein oder mehrere Versteifungswinkel 12a zwischen wenigstens einer der Platten 9, 10 und der Platte 11 vorgesehen sein.A carrier bracket 8 is fastened to the drive unit 1, in particular screwed. The support bracket 8 is U-shaped and includes according to the illustrated embodiment two mutually spaced, parallel plates 9, 10, which are screwed onto the drive unit 1 and through a vertical plate 11 are interconnected. To this extent, the support bracket 8 can be in one piece or consist of several welded parts. In addition, you can one or more stiffening angles 12a between at least one of the plates 9, 10 and the plate 11 may be provided.

Die Trägerkonsole 8 trägt eine Steuerschiene 12, die sich parallel zur Achse des Fräskopfes erstreckt, mit Abstand hierzu angeordnet und mit der Platte 11 verschraubt ist. Die Steuerschiene 12 endet im wesentlichen etwa auf der Höhe des freien Endes des Fräswerkzeugs 2. Der Abstand zwischen der Steuerschiene 12 und dem Fräswerkzeug 2 ist vorzugsweise derart gewählt, daß hierzwischen dickere Stücke wie Ziegelsteine oder Kieselsteine entsprechender Größe, die vom Fräswerkzeug 2 als solche losgebrochen werden können, ohne weiteres aus dem Fräsbereich durch die Schnecke 5 weg transportiert werden können, ohne daß die Steuerschiene 12 stört.The support bracket 8 carries a control rail 12 which is parallel to the axis of the milling head, arranged at a distance from it and with the plate 11 is screwed. The control rail 12 essentially ends approximately at the level of free end of the milling tool 2. The distance between the control rail 12 and the milling tool 2 is preferably chosen such that thicker in between Pieces such as bricks or pebbles of the appropriate size, from the Milling tool 2 can be broken off as such, without further ado Milling area can be transported away by the screw 5 without the Control rail 12 interferes.

Die Steuerschiene 12 ist vorzugsweise muldenförmig ausgebildet, wobei die Muldenöffnung dem Fräswerkzeug 2 zugewandt ist. Die Platte 11 der Trägerkonsole 8 ist zweckmäßigerweise entsprechend geformt, so daß diese an der Steuerschiene 12 anliegt und auch die seitlichen, die Mulde bildenden Schenkel 12' der Steuerschiene 12 mit der Platte 11 verschraubt werden können.The control rail 12 is preferably trough-shaped, the Trough opening facing the milling tool 2. The plate 11 of the support bracket 8 is appropriately shaped so that it is on the control rail 12 abuts and also the lateral legs 12 'forming the trough Control rail 12 can be screwed to the plate 11.

Die Steuerschiene 12 ist zweckmäßigerweise in Richtung der Achse des Fräskopfes mechanisch oder hydraulisch verstellbar. Beispielsweise ist auf der Trägerkonsole 8 ein U-förmiger Halter 13 mit einer Lasche 14 befestigt, die eine Stellschraube 15 aufnimmt, die mit einer Gewindehülse 16 an der Steuerschiene 12 in Eingriff steht, so daß durch Drehen der Stellschraube 15 die Steuerschiene 12 gegenüber der Trägerkonsole 8 unter Führung durch die Platten 9, 10 verschiebbar ist. Die Platte 11 oder die Steuerschiene 12 sind mit sich in Richtung der Achse des Fräskopfes erstreckenden Langlöchern versehen, um ein Festschrauben der Steuerschiene 12 in einer gewünschten Position zum Fräswerkzeug 2 zu ermöglichen. - Es kann auch eine hydraulische Verriegelung zwischen Trägerkonsole 8 und Steuerschiene 12 vorgesehen sein.The control rail 12 is advantageously in the direction of the axis of the Milling head mechanically or hydraulically adjustable. For example, on the Carrier console 8 is attached to a U-shaped holder 13 with a tab 14, the one Setscrew 15 takes, which with a threaded sleeve 16 on the control rail 12th is engaged so that the control rail 12 by turning the adjusting screw 15 displaceable relative to the carrier console 8 under guidance by the plates 9, 10 is. The plate 11 or the control rail 12 are with themselves in the direction of the axis of Milling head extending slots provided for screwing the Control rail 12 to the milling tool 2 in a desired position enable. - There can also be a hydraulic lock between Carrier console 8 and control rail 12 may be provided.

Je nach Bodenbeschaffenheit, z.B. Beton, Asphalt, Felsboden od.dgl., wird die Steuerschiene 12 durch entsprechendes Schwenken des Fräskopfes auf den Boden mehr oder weniger schräg aufgelegt. Je härter der Boden, desto mehr sollte ein Winkel zur Bodenoberfläche nahe 0° gewählt werden. Je weicher der Boden, desto größer kann der Winkel zur Bodenoberfläche gewählt werden. Die Steuerschiene 12 sitzt dann mit ihrem freien Ende, das zum Bagger zeigt, auf dem Boden auf. Auf diese Weise wird beim beginnenden Fräsen verhindert, daß die dabei auftretenden Seitenkräfte das Fräsen beeinträchtigen, vielmehr werden diese am Ort des Entstehens über die Steuerschiene 12 aufgefangen. Nach Erreichen der Frästiefe bzw. mit fortschreitender Frästiefe kann dann der Fräskopf entsprechend aufgerichtet werden. Damit läßt sich der Fräskopf vom Baggerfahrer leicht und problemlos handhaben.Depending on the nature of the soil, e.g. Concrete, asphalt, rock floor or the like the control rail 12 by swiveling the milling head accordingly Floor more or less slanted. The harder the floor, the more you should an angle to the floor surface close to 0 ° can be selected. The softer the floor the greater the angle to the floor surface can be chosen. The Control rail 12 then sits with its free end, which faces the excavator, on the Floor on. In this way it is prevented at the beginning of milling that the lateral forces that occur thereby impair the milling, rather they become caught on the control rail 12 at the point of origin. After reaching the The milling head can then be adjusted accordingly, or as the milling depth progresses be erected. This allows the milling head to be easily and by the excavator operator easy to handle.

Außerdem kann die Steuerschiene 12 bei muldenförmiger Ausbildung, durch die die Steifigkeit der Steuerschiene 12 vergrößert wird, auch als Schaufel verwendet werden, wobei die Platte 10 eine Rückwand für die Schaufel bildet, um das durch Fräsen gelöste Material wie mit einem Tieflöffel eines Baggers zu entfernen. Hierzu ist es notwendig, daß die Breite der Steuerschiene 12 etwas geringer als die Breite des Fräswerkzeugs 2 ist.In addition, the control rail 12 with a trough-shaped design which increases the rigidity of the control rail 12, also as a blade are used, the plate 10 forming a rear wall for the blade to the material loosened by milling like with a backhoe of an excavator remove. For this it is necessary that the width of the control rail 12 is somewhat is smaller than the width of the milling tool 2.

Durch die Steuerschiene 12 läßt sich auch eine Frästiefenbegrenzung vornehmen. Außerdem ergibt sich ein sehr günstig gebrochenes Mahlgut, daß sich zur späteren Wiederfüllung besser eignet.The control rail 12 can also be used to limit the milling depth make. In addition, there is a very cheaply broken ground that more suitable for later refilling.

Durch Änderung der Platten 9, 10 (anderes Lochbild) läßt sich die Trägerkonsole 8 mit der Steuerschiene 12 bei unterschiedlichen Typen von Längs- und Querschneidkopffräsen einsetzen.By changing the plates 9, 10 (different hole pattern), the Carrier console 8 with the control rail 12 for different types of longitudinal and cross cutting head milling.

Die Steuerschiene 12 kann auch gerundet, beispielsweise im Schnitt teilkreisförmig ausgebildet sein.The control rail 12 can also be rounded, for example in section be part-circular.

Bei der in Fig. 3 dargestellten Ausführungsform ist zwischen dem Flansch des Baggerarms 7 und demjenigen des Antriebsaggregats 1 die Platte 10 eingespannt, an der die Trägerkonsole 8 für die Steuerschiene 12 angebracht ist. Die muldenartige Steuerschiene 12 ist rückseitig durch Rippen 17 verstärkt und über die Stellschraube 15 zur Trägerkosole 8 - nach Lösen entsprechender Verschraubungen zwischen Trägerkonsole 8 und Steuerschiene 12 - höhenverstellbar. Die Trägerkonsole 8 ist unterseitig über eine Abstützung 18 (hier bestehend aus einer an der Trägerkonsole 8 befestigten Gabel und einer damit verschraubten, am Antriebsaggregat 1 befestigten Lasche) an dem Antriebsaggregat 1 angestützt.In the embodiment shown in Fig. 3 is between the flange of the excavator arm 7 and that of the drive unit 1, the plate 10 clamped on which the support bracket 8 for the control rail 12 is attached. The trough-like control rail 12 is reinforced on the back by ribs 17 and over the set screw 15 to the carrier cosole 8 - after loosening corresponding Screw connections between support bracket 8 and control rail 12 - height-adjustable. The support bracket 8 is on the underside via a support 18 (here consisting of a fork attached to the support bracket 8 and a so screwed, attached to the drive unit 1 tab) on the Drive unit 1 supported.

Bei dieser Ausführungsform ist jeweils ein Fräswerkzeuge 2 (schematisch durch die beiden Kreise R1 und R2 dargestellt, deren Radiusdifferenz die maxiamle Frästiefe ergibt) auf jeder Seite des Antriebsaggregats 1 angeordnet, so daß die Fräswerkzeuge 2 koaxial zueinander und horizontal angeordnet sind. Um eine vorgesehene Frästiefe festzulegen und damit kein Hüpfen bzw. ungleichmäßig tiefes Fräsen zu bewirken, ist ein dickwandiger, runder Bügel 19, der die Frästiefe bestimmt, vorgesehen. Der Bügel 19 kann zum Erzielen entsprechender Frästiefen auswechselbar sein, jedoch ist er statt dessen zweckmäßigerweise einerseits über ein Gelenk 20 am Antriebsaggregat 1 angelenkt und andererseits über eine Stellschraube 21 (oder eine Stellspindel) an einer Lasche 22 des Antriebsaggregats 1 gehalten, so daß der in seinem Auflagebereich kreisbogenförmige Bügel 19 in seinem Abstand gegenüber dem Antriebsaggregat 1 verstellbar ist. Der Bügel 19 besitzt zweckmäßigerweise an seiner dem Antriebsaggregat 1 zugewandten Seite Rippen 23 zur Verstärkung und bei größter Frästiefe auch zur Abstützung.In this embodiment, a milling tool 2 (schematic represented by the two circles R1 and R2, whose radius difference is the maxiamle Milling depth results) arranged on each side of the drive unit 1, so that the Milling tools 2 are arranged coaxially to one another and horizontally. To one Determine the intended milling depth and therefore no bouncing or unevenly To effect deep milling is a thick-walled, round bracket 19 that the milling depth determined, provided. The bracket 19 can be used to achieve corresponding milling depths be interchangeable, but instead it is conveniently on the one hand a joint 20 is articulated on the drive unit 1 and on the other hand via a Set screw 21 (or an adjusting spindle) on a tab 22 of the drive unit 1 held so that the circular arc-shaped bracket 19 in its support area its distance from the drive unit 1 is adjustable. The bracket 19 suitably has on its side facing the drive unit 1 Ribs 23 for reinforcement and, for the greatest milling depth, also for support.
