Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Aufbereiten von Schlaglöchern in asphaltierten Straßen zum Zwecke anschließ ender Ausbesserung, z.B. mit einem Kleinschlag-Bitumenge misch.The invention relates to a device for processing Connect potholes in asphalt roads for the purpose repair, e.g. with a bit of bitumen mix.
Nach der bisherigen Praxis werden Schlaglöcher mit Ausbesse rungsmaterial mittels Schaufel verfüllt, mit Sand bestreut und verdichtet. Hierbei ergibt diese Art der Verfüllung völ lig unterschiedliche Schichtdicken, wobei sich die dünnsten Schichtanteile, meistens wegen ungenügender Abbindung mit dem Untergrund, nach kurzer Zeit lösen.According to previous practice, potholes become gnawing Filling material with a shovel, sprinkled with sand and condensed. This type of backfill results in full lig different layer thicknesses, the thinnest Shift shares, mostly due to insufficient binding with loosen the surface after a short time.
Eine bessere Schlaglochaufbereitung erfolgt mit Preßluft meißeln, wobei aber der auszufüllende Untergrund nur bedingt eben wird und das Entfernen der abgeschlagenen Asphaltreste sehr sorgfältig erfolgen muß. Andernfalls ist auch hierbei die Abbindung zwischen Untergrund und Verfüllmaterial mehr oder weniger mangelhaft.A better pothole preparation is done with compressed air chisel, but the surface to be filled in is only conditional leveling and removing the chipped asphalt remains must be done very carefully. Otherwise, this is also here the bonding between the substrate and backfill material more or less deficient.
Es ist Aufgabe der Erfindung eine Vorrichtung zu schaffen, mittels welcher Schlaglöcher in asphaltierten Straßen so aufbereitet werden können, daß eine langlebige, d.h., qua litativ hochwertige Ausbesserung mit gleichmäßiger Schicht dicke ermöglicht wird.It is an object of the invention to provide a device what potholes in asphalt roads like that can be prepared so that a long-lasting, i.e., qua literally high-quality repair with an even layer thickness is enabled.
Gemäß der Erfindung erfolgt dieses dadurch, daß die Vorrich tung aus einer Rohrachse besteht, an deren unterem Ende ra dial und in gleichen Winkeln untereinander und in axial gleichliegenden Ebenen Öffnungen und nutenförmige Aussparun gen eingebracht sind.According to the invention, this is done in that the Vorrich tion consists of a pipe axis, at the lower end of which ra dial and at equal angles to each other and axially same level openings and groove-shaped recess are introduced.
In diesen sind kreisrund ringförmig gebogene, aus Flachstahl bestehende Schneiden senkrecht zur Rohrachse stehend fest eingesetzt. Der Umfang der Schneiden umfaßt aber nur einen Dreiviertel-Kreisring, wobei die oberen Enden derselben mit der Innenwand der Rohrachse bündig abschneiden. In dieser sind im Bereich der Schneiden mindestens drei um 120° versetzte Bohrungen radial angeordnet, deren Achsen in einer Ebene mit den Mitten der Schneiden liegen. These are made of flat steel and have a circular, circular shape existing cutting edges standing perpendicular to the pipe axis used. The scope of the cutting edges includes only one Three-quarter annulus, with the top ends of the same with Cut the inner wall of the pipe axis flush. In this area there are at least three microns in the area of the cutting edges 120 ° offset holes radially arranged, their axes in lie on one level with the centers of the cutting edges.
Ein besonderes Merkmal der Erfindung ist, daß die Achsen die ser um 120° versetzten Bohrungen mit einer zur Achse der Rohrachse zeigenden radialen Linie einen Winkel von 30° ein schließen.A special feature of the invention is that the axes bores offset by 120 ° with one to the axis of the Radial line showing the pipe axis at an angle of 30 ° shut down.
In der Zeichnung ist ein Ausführungsbeispiel gemäß der Erfin dung dargestellt und wird im folgenden näher beschrieben. Es zeigen:In the drawing is an embodiment according to the inven tion and is described in more detail below. Show it:
Fig. 1 die Ansicht einer Vorrichtung, Fig. 1 is a view of a device,
Fig. 2 einen Schnitt nach der Linie A-A der Fig. 1, Fig. 2 shows a section along the line AA of Fig. 1,
Fig. 3 die Rohrachse ohne Schneiden und Fig. 3, the pipe axis without cutting and
Fig. 4 einen Schnitt nach der Linie B-B der Fig. 3. Fig. 4 shows a section along the line BB of FIG. 3.
Nach Fig. 1 besteht die Vorrichtung aus einer Rohrachse 1, die z.B. von einem auf dieser angebrachten Rohrmotor 10 getrie ben wird. Dieser ist zweckmäßigerweise auf einer dreidimen sional bewegbaren Traverse befestigt.According to Fig. 1, the device consists of a tubular axis 1 , which is driven, for example, by a tubular motor 10 mounted thereon. This is expediently attached to a three-dimensionally movable traverse.
Am unteren Ende der Rohrachse 1 sind nach den Fig. 1 und 3 radial in gleichen Winkeln untereinander und in axial gleichliegenden Ebenen, im Ausführungsbeispiel jeweils zwölf, Öffnungen 2 und nutenförmige Aussparungen 3 eingebracht. In diesen sind gemäß den Fig. 1 und 2 kreisrundgebogene Schnei den 4, die zwangsläufig senkrecht zur Rohrachse 1 stehen, fest eingesetzt. Der Umfang der Schneiden umfaßt einen Dreiviertel- Kreisring, deren obere Enden 4′ etwa bündig mit der Innenwand der Rohrachse 1 abschneiden. Die unteren Enden 4′′ ragen in die Rohrachse hinein.At the lower end of the tube axis 1 , according to FIGS. 1 and 3, openings 2 and groove-shaped recesses 3 are introduced radially at equal angles to one another and in axially identical planes, in each case twelve in the exemplary embodiment. In this are shown in FIGS. 1 and 2 circular curved Schnei to 4, which are necessarily perpendicular to the axis of the tube 1 is fixedly inserted. The circumference of the cutting edges comprises a three-quarter circular ring, the upper ends 4 'cut approximately flush with the inner wall of the tube axis 1 . The lower ends 4 '' protrude into the tube axis.
In dieser sind nach den Fig. 1, 3 und 4 im Bereich der Schnei den um 120° versetzte Bohrungen 5, 5′angeordnet. Deren Achsen liegen in einer Ebene mit den Mitten der Schneiden 4. Nach Fig. 4 können die Achsen 6 der Bohrungen 5′ mit einer radialen, zur Achse der Rohrachse 1 zeigenden Linie 7 einen Winkel von 30° bilden.In this, according to FIGS. 1, 3 and 4, the 120 ° offset bores 5 , 5 'are arranged in the region of the cut. Their axes lie in one plane with the centers of the cutting edges 4 . According to FIG. 4, the axes of the bores 6 may be 5 'with a radial, pointing to the axis of the tube axis 1 line 7 form an angle of 30 °.
Die Vorrichtung gemäß der Erfindung stellt eine Art Fräser dar. Die dreidimensional bewegbare Traverse 11, die z.B. auf einem entsprechenden Fahrzeug angebracht ist, wird über das Schlagloch einer asphaltierten Fahrbahndecke gebracht. Die Aufarbeitung eines solchen Schlagloches wird mittels der vom vom Rohrmotor 10 getriebenen Vorrichtung vorgenommen. Durch diese wird das Schlagloch bis auf den Unterbau der Fahr bahndecke vorzugsweise in rechteckiger Form ausgefräst. An der Rohrachse 1 ist oben eine Absaugvorrichtung angeschlos sen, welche das ausgefräste Material durch die untere Rohr achsenöffnung 1′ sowie die Bohrungen 5 bzw. 5′absaugt. Hier bei ist besonders die Wirkung der Bohrungen 5′ von Bedeutung, die auf Grund ihrer Stellung eine besondere Wirbel- und Saug wirkung haben.The device according to the invention represents a type of milling cutter. The three-dimensionally movable traverse 11 , which is mounted, for example, on a corresponding vehicle, is brought over the pothole of an asphalt pavement. Such a pothole is worked up by means of the device driven by the tubular motor 10 . Through this, the pothole is milled down to the substructure of the pavement, preferably in a rectangular shape. On the pipe axis 1 , a suction device is ruled out, which sucks the milled material through the lower pipe axis opening 1 'and the holes 5 and 5 '. Here is particularly the effect of the holes 5 'of importance, which have a special vortex and suction effect due to their position.
Das ausgefräste, saubere Schlagloch wird anschließend mit ent sprechendem Material verfüllt und gewalzt. Dadurch ergibt sich eine gleichmäßig dicke Ausbesserungsschicht.The milled, clean pothole is then ent filled and rolled talking material. This results in a uniformly thick touch-up layer.
