Description
Die Erfindung betrifft eine selbstfahrende oder an eine Zugmaschine ankoppelbare Vorrichtung zur Her stellung von Fahrbahnen durch Stabilisierung unge nügend tragfähiger Böden oder durch Recycling repa raturbedürftiger Straßendecken, indem die obere Boden- oder Straßenschicht mit zumindest einer in einer Arbeitskammer umlaufenden, höhenverstellba ren Rotorfräse abgelöst, zerkleinert und mit Binde mittel vermischt wird, wobei der Rotorfräse auf grund der Schrägstellung ihrer Fräswerkzeuge eine bestimmte Drehrichtung vorgegeben ist und die Ar beitskammer an ihrer Rückwand eine verstellbare Klappe aufweist, um das Höhenniveau des austre tenden Materials zu regulieren.The invention relates to a self-propelled or a tractor coupling device for manufacture Position of roadways through stabilization sufficient load-bearing floors or through recycling repa road surfaces in need of repair by the upper Soil or road layer with at least one in a working chamber revolving, height adjustable loosened, shredded and with a bandage medium is mixed, with the rotor cutter on due to the inclination of their milling tools certain direction of rotation is specified and the Ar an adjustable chamber on the back wall Flap has to the level of the austre regulating material.
Diese Geräte werden einerseits zur Stabilisierung von Lehm- und Tonböden verwendet, indem Zement oder Kalk in verschiedener Form lose oder mit Was ser auf den Boden aufgebracht und durch den Fräs vorgang mit dem Boden vermischt werden. Anderer seits können diese Geräte auch zur Reparatur al ter, brüchiger Straßen eingesetzt werden, indem die zu erneuernden Straßenschichten abgeschält, zerkleinert und im Bereich der Rotorfräse mit Bin demittel, etwa Bitumen vermischt werden. In beiden Fällen wird der neue Belag anschließend durch Gra der geglättet und durch Walzen verdichtet.On the one hand, these devices are used for stabilization of clay and clay soils used by cement or lime in various forms loose or with what water applied to the floor and through the cutter operation to be mixed with the soil. Other on the one hand, these devices can also be used for repair al brittle roads are used by peeled off the road layers to be renewed, crushed and in the area of the rotor milling machine with bin medium, such as bitumen. In both The new covering is then felled by Gra which is smoothed and compacted by rolling.
Grundsätzlich werden diese Geräte mit zwei Fräs drehrichtungen gebaut. Entweder entgegen der Fahrt richtung, genannt "Down Cut" oder in Fahrtrichtung, genannt "Up Cut". Im ersten Fall wird der Fahran trieb durch die Fräse gebremst, im zweiten Fall un terstützt sie den Fahrantrieb.Basically, these devices with two milling directions of rotation built. Either against the journey direction, called "Down Cut" or in the direction of travel, called "Up Cut". In the first case, the Fahran driven by the milling machine, in the second case un it supports the travel drive.
Je nach den Bodenverhältnissen und den übrigen Rand bedingungen führt im einen Fall die Fräsdrehrichtung entgegen der Fahrtrichtung, im anderen Fall die um gekehrte Drehrichtung zu besseren Ergebnissen. Wün schenswert wäre also ein Gerät, das je nach Anwen dungsfall schnell von "Down Cut" auf "Up Cut" oder umge kehrt verstellt werden kann. Dazu müßte aber nicht nur die Drehrichtung der Fräse verändert werden, sondern insbesondere müßte die Position der Fräs werkzeuge an die neue Drehrichtung angepaßt wer den. Vor allem letzteres bedarf jedoch eines erheb lichen technischen Aufwandes.Depending on the soil conditions and the remaining edge In one case, the conditions lead to the milling direction against the direction of travel, in the other case around reversed direction of rotation for better results. Wish It would be worthwhile to use a device that, depending on the application case quickly from "Down Cut" to "Up Cut" or vice versa returns can be adjusted. But this would not have to be the case only the direction of rotation of the milling machine can be changed, but in particular the position of the milling tools adapted to the new direction of rotation the. However, the latter in particular requires a considerable amount technical effort.
Hiervon ausgehend liegt die Aufgabe der vorliegen den Erfindung darin, ein Gerät der eingangs be schriebenen Gattung zu entwickeln, das auf einfa che Weise eine Umschaltung der Betriebsweise zwi schen "Down Cut" und "Up Cut" gestattet und das in beiden Betriebsweisen gleichermaßen zur Boden stabilisierung wie auch zur Reparatur beschädigter Straßen geeignet ist.The task of the present is based on this the invention therein, a device of the beginning to develop the genre that is based on simple che way of switching the operating mode between "Down Cut" and "Up Cut" allowed and that to the ground in both modes of operation stabilization as well as for repairing damaged ones Roads is suitable.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Arbeitskammer auch an ihrer in Fahrtrich tung vorderen Wand eine verstellbare Klappe zur Re gulierung des Höhenniveaus aufweist und daß die Vorrichtung unter Beibehaltung der Rotorfräsen drehrichtung auch rückwärts verfahrbar ist.According to the invention, this object is achieved by that the working chamber also at their in driving direction an adjustable flap on the front wall Gulation of the height level and that the Device while maintaining the rotor milling Direction of rotation can also be moved backwards.
Die Erfindung geht also von der Erkenntnis aus, daß der gewünschte Wechsel zwischen "Down Cut" und "Up Cut" auch ohne Drehrichtungswechsel der Fräse möglich wird, wenn man die Fahrtrichtung der Ma schine umkehrt und wenn man dafür sorgt, daß bei der Rückwärtsfahrt hinter der Fräse ebenfalls das Höhenniveau des zerkleinerten, abgelegten Materi als reguliert werden kann. Die Erfindung gestattet es somit, mit ein und demselben Gerät ohne jegli che Umrüstarbeiten wahlweise in der einen oder in der anderen Betriebsweise zu fahren.The invention is based on the knowledge that the desired change between "Down Cut" and "Up Cut" even without changing the direction of rotation of the milling cutter is possible if you change the direction of travel of Ma reverse and if you make sure that at the backward drive behind the milling machine that too Height level of the shredded, deposited material than can be regulated. The invention allows it, therefore, with the same device without any retrofitting work either in one or in the other mode of operation.
Ein weiterer Vorteil der Erfindung besteht darin, daß in denjenigen Fällen, wo die Drehrichtung des Rotors relativ zur Fahrtrichtung der Maschine kei ne Bedeutung hat, das bisher notwendige Wenden nach jedem Arbeitsgang wegfallen und der nächste Übergang einfach durch Rückwärtsfahrt begonnen werden kann. Dies erweist sich gerade bei engen Baustellen, wo man schlecht manövrieren kann, als sehr günstig.Another advantage of the invention is that in those cases where the direction of rotation of the Rotors relative to the machine's direction of travel ne meaning, the previously necessary turning drop out after each step and the next Transition started simply by reversing can be. This is particularly evident in tight spaces Construction sites where it is difficult to maneuver as attractively priced.
Nach dem Fahrrichtungswechsel braucht die bisher für die Höhenregulierung verwendete Klappe nicht nach oben weggeklappt zu werden. Vielmehr empfiehlt es sich, sie lediglich in eine Rückschlagschutz- Position zu verstellen, damit die Rotorfräse kein Material nach vorn in Fahrtrichtung herausschleu dern kann.So far, after the change of direction flap not used for height adjustment to be folded upwards. Rather recommends it into a kickback protection To adjust position so that the rotor milling machine no Throw material out in the direction of travel who can.
Die beiden Klappen können beispielsweise verschieb bar an der Arbeitskammer gelagert sein, im allge meinen ist aber eine Schwenklagerung vorzuziehen. Ihre Verstellung erfolgt zweckmäßig durch Hydrau likzylinder.The two flaps can move, for example be stored in the working chamber, generally but a swivel bearing is preferable. They are expediently adjusted by Hydrau lik cylinder.
Weitere Merkmale und Vorteile des Anmeldungsgegen standes ergeben sich aus der nachfolgenden Beschrei bung eines Ausführungsbeispieles anhand der Zeich nung; dabei zeigtOther features and advantages of the counter-application status result from the following description Exercise of an embodiment using the drawing nung; shows
Fig. 1 eine schematische Seitenansicht des er findungsgemäßen Gerätes und Fig. 1 is a schematic side view of the device according to the invention and
Fig. 2 einen vergrößerten Ausschnitt. Fig. 2 shows an enlarged section.
Gemäß Fig. 1 besteht das Mehrgang-Bodenverfesti gungsgerät aus einem Grundgestell 1, das über ein vorderes Radpaar 2 und hintere Lenkräder 3 ver fahrbar ist. Ein Antriebsmotor 4 treibt über eine Fahrpumpe 5 die vorderen Antriebsräder 2 und über eine weitere Pumpe 6 eine Rotorfräse 7. Die Fräse 7 weist eine horizontale Drehachse auf und ist über endständig angreifende Ausleger 8 höhenverstellbar am Grundgestell 1 gelagert. Die Einstellung der Ar beitstiefe der Fräse 7 erfolgt durch Hydraulikzylin der 9, die einerseits am Grundgestell 1, anderer seits an den Auslegern 8 angreifen.Referring to FIG. 1, the multi-speed Bodenverfesti supply device of a base frame 1 which through a front pair of wheels 2 and rear steering wheels 3 is movable ver. A drive motor 4 drives the front drive wheels 2 via a traction pump 5 and a rotor milling machine 7 via a further pump 6 . The milling machine 7 has a horizontal axis of rotation and is mounted on the base frame 1 in a height-adjustable manner by means of cantilevers 8 which engage in the end. The setting of the working depth of the milling machine 7 is carried out by hydraulic cylinder 9 , which on the one hand engage on the base frame 1 and on the other hand on the arms 8 .
Oben, vorn, hinten und seitlich ist die Fräse 7 von einem Gehäuse 10 umgeben. Dieses Gehäuse be grenzt eine Arbeitskammer, in der die Bodenschicht abgelöst, zerkleinert und gegebenenfalls mit Zu satzstoffen vermischt wird. Es stellt sicher, daß die von der Rotorfräse herumgeschleuderten Teile nicht wegfliegen.The router 7 is surrounded by a housing 10 at the top, front, rear and side. This housing defines a working chamber in which the bottom layer is detached, crushed and, if necessary, mixed with additives. It ensures that the parts thrown around by the rotary milling machine do not fly away.
Das Gehäuse 10 ist über einen Arm 11 ebenfalls schwenk bar am Grundgestell 1 gelagert und kann durch einen Hydraulikzylinder 12 oder eine Kette, die das Niveau hält, auf die gewünschte Höhe eingestellt werden.The housing 10 is also pivotally mounted on the base frame 1 via an arm 11 and can be adjusted to the desired height by a hydraulic cylinder 12 or a chain that maintains the level.
Wesentlich ist nun, daß die Fräse 7 sowohl bei Vor wärts- wie auch bei Rückwärtsfahrt des Gerätes im mer in gleicher Drehrichtung, im Ausführungsbei spiel entsprechend dem eingezeichneten Pfeil 13 umläuft und daß das Gehäuse 10 an seinem quer zur Fahrtrichtung verlaufenden unteren Rand sowohl vorn wie auch hinten eine verschwenkbare Klappe 14 bzw. 15 aufweist. Von diesen beiden Klappen befindet sich jeweils die in Fahrtrichtung hinter der Frä se 7 liegende Klappe in ihrer Aktivstellung, um das Höhenniveau des austretenden Materials zu re gulieren, während die gegenüberliegende andere Klap pe nur die Funktion erfüllt, ein Herausschleudern des Materials aus der Arbeitskammer zu verhindern.It is now essential that the milling machine 7 rotates both in the forward and reverse direction of the device in the same direction of rotation, in the game of execution according to the arrow 13 shown in the drawing, and that the housing 10 at its lower edge running transversely to the direction of travel both at the front and also has a pivotable flap 14 or 15 at the rear. Of these two flaps, the flap lying in the direction of travel behind the cutter 7 is in its active position in order to regulate the height level of the escaping material, while the opposite other flap only fulfills the function of throwing the material out of the working chamber prevent.
Im Zusammenwirken mit dem heb- und senkbaren Ge häuse 10 können die Klappen 14 und 15 auch dazu verwendet werden, die Verweilzeit der abgefrästen Teilchen im Wirkungsbereich des Rotors und damit die Zerkleinerungswirkung zu beeinflussen. Dies ist ein weiterer Vorteil der beidseitigen Klappen anordnung.In cooperation with the lifting and lowering Ge housing 10 , the flaps 14 and 15 can also be used to influence the residence time of the milled particles in the effective range of the rotor and thus the crushing effect. This is another advantage of the double-sided flap arrangement.
Die Verstellung der Klappen erfolgt jeweils durch Hydraulikzylinder 16 bzw. 17. Durch eine Steuer automatik kann automatisch dafür gesorgt werden, daß bei Wechsel der Fahrtrichtung die beiden Klap pen jeweils in ihre richtige Stellung verschwenkt werden. Im übrigen erfolgt die Regulierung aller vorgenannter Hydraulikzylinder in an sich bekann ter Weise vom Fahrersitz aus.The flaps are adjusted by hydraulic cylinders 16 and 17, respectively. Automatic control can automatically ensure that when the direction of travel changes, the two flaps are each pivoted into their correct position. Incidentally, the regulation of all the aforementioned hydraulic cylinders takes place in a manner known per se from the driver's seat.
Die zusätzliche, in Fahrtrichtung vorn liegende Klappe bietet nicht zuletzt den Vorteil, daß das Volumen unter dem haubenförmigen Gehäuse 10 verän dert werden kann, ohne daß dadurch das Höhenniveau des hinter der Rotorfräse 7 austretenden Materials verfälscht wird, weil letzteres allein von der in Fahrtrichtung hinten liegenden Klappe bestimmt wird. Mit der vorderen Klappe kann somit die Menge des vom Rotor umgewälzten Materials beeinflußt werden. Dies ist besonders wichtig, wenn Unebenheiten in der zu fräsenden Bodenschicht ausgeglichen werden sollen, etwa wenn mehr Material als sonst benötigt wird, um Löcher auszufüllen.The additional flap lying in the direction of travel has the last but not least the advantage that the volume under the hood-shaped housing 10 can be changed without thereby falsifying the height of the material emerging behind the rotary milling machine 7 because the latter is caused solely by the rear in the direction of travel lying flap is determined. With the front flap, the amount of material circulated by the rotor can thus be influenced. This is particularly important if unevenness in the ground layer to be milled is to be leveled out, for example if more material than usual is required to fill holes.
In diesem Zusammenhang empfiehlt es sich, die bei den Klappen 14 und 15 an ihren seitlichen Enden mit Randblechen 14a bzw. 15a zu versehen. Diese Randble che stellen sicher, daß seitlich kein Material aus tritt, wenn die Klappen in Pfeilrichtung verschwenkt werden.In this context it is advisable to provide the flaps 14 and 15 with edge plates 14 a and 15 a at their lateral ends. This Randble che ensure that no material emerges from the side when the flaps are pivoted in the direction of the arrow.
