Abstract

PCT No. PCT/EP97/00932 Sec. 371 Date Mar. 29, 1999 Sec. 102(e) Date Mar. 29, 1999 PCT Filed Feb. 26, 1997 PCT Pub. No. WO97/32085 PCT Pub. Date Sep. 4, 1997A piste-preparation device for preparing a half-pipe comprises at least one tool adjustably mounted on a piste vehicle, and lateral members which are laterally disposed relative to the tool and can essentially be assigned to side walls of the half-pipe. To prepare a half-pipe even in cases where the surface is hard and, at the same time, to remove a large amount of material, in particular from the half-pipe side walls, each lateral member comprises removal means designed with removal tools which can move substantially transversely to the direction of travel of the piste vehicle.

Description

Die Erfindung betrifft eine Pistenpräpariervomchtung zur Präparation einer Half-Pipe mit wenigstens einem an einem Pistenfahrzeug verstellbar gelagerten Arbeitsgerät und seitlich zu diesem angeordneten, im wesentlichen Seitenwände der Half-Pipe zuordbaren Seitenteilen.The invention relates to a piste grooming device for the preparation of a half pipe at least one implement that is adjustably mounted on a snow groomer and on the side can be assigned to this arranged, essentially side walls of the half pipe Side panels.

Als Half-Pipes werden kanal- oder rinnenförmige Pisten für Snowboards bezeichnet. Zur Präparation einer solchen Half-Pipe weist eine vorbekannte Pistenpräpariervorrichtung der obengenannten Art, wie sie beispielsweise aus der Zeitschrift "Internationale Seilbahn-Rundschau" 5/1993, Seiten 42 bis 44 bekannt ist, seitlich an einem Arbeitsgerät angeordnete Seitenschilder auf. Diese sind so ausgeformt, daß die Herstellung und Bearbeitung der Seitenwände der Half-Pipe mit einem Wettkampfprofil möglich ist.Half-pipes are channel-shaped or channel-shaped slopes for snowboards. For Preparation of such a half pipe has a previously known slope preparation device of the type mentioned above, for example from the magazine "Internationale Seilbahn-Rundschau" 5/1993, pages 42 to 44 is known, on the side of an implement arranged side plates. These are shaped so that the manufacture and processing the side walls of the half pipe with a competition profile is possible.

Bei der vorbekannten Pistenpräpariervomchtung hat sich allerdings als Nachteil gezeigt, daß durch die Seitenschilder nur eine geringe Materialverfrachtung und diese hauptsächlich nur in Fahrtrichtung möglich ist. Weiterhin können harte Oberflächen nur schwieng oder gar nicht bearbeitet werden.With the previously known slope grooming device, however, it has been shown as a disadvantage that that by the side plates only a small amount of material and this mainly is only possible in the direction of travel. Furthermore, hard surfaces can only difficult or not processed at all.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Pistenpräpariervorrichtung der eingangs genannten Art dahingehend zu verbessern, daß eine Half-Pipe auch bei harter Oberfläche präpariert werden kann und gleichzeitig eine größere Materialmenge, insbesondere von den Seitenwänden der Half-Pipe abräumbar ist.The invention is therefore based on the object, a slope preparation device type mentioned to improve in that a half pipe even with hard Surface can be prepared and at the same time a larger amount of material, can be cleared in particular from the side walls of the half pipe.

Diese Aufgabe wird bei der obengenannten Pistenpräpariervorrichtung dadurch gelöst, daß jedes Seitenteil eine mit im wesentlichen quer zur Fahrtrichtung des Pistenfahrzeugs beweglichen Räumwerkzeugen ausgebildete Räumeinrichtung zur Bearbeitung einer Pistenoberfläche der Half-Pipe aufweist. Durch die quer zur Fahrtrichtung beweglichen Räumwerkzeuge kann Material von den Seitenwänden der Half-Pipe in größerer Menge abgeräumt werden. Außerdem kann ein Abräumen des Materials auch bei stehendem Pistenfahrzeug erfolgen, um beispielsweise die Half-Pipe an dieser Stelle intensiver zu bearbeiten. Die Räumwerkzeuge sind so ausgearbeitet, daß sie auch eine härtere Pistenoberfläche bearbeiten können.This problem is solved in the above-mentioned slope preparation device by that each side part has a substantially transverse to the direction of travel of the snow groomer Movable broaching tools trained broaching device for processing has a slope surface of the half pipe. Through the movable across the direction of travel Broaching tools can remove material from the side walls of the half pipe in larger sizes Quantity to be cleared. In addition, the material can be cleared even when it is standing Snow groomer take place, for example, to make the half-pipe more intense at this point to edit. The broaching tools are designed so that they also a can work harder slope surface.

Aus der EP 0 151 757 A2 ist eine Schneeschleuder mit seitlich zu dieser angeordneten Zuführpflügen bekannt. Diese Zuführpflüge dienen zur Vergrößerung des Eintrittsquerschnitts der Schneeschleuder. Ein typisches Anwendungsgebiet der Schneeschleudern ist der Einsatz auf Flugplätzen, wo es besonders auf hohe Räum- und Fördergeschwindigkeiten ankommt. Jeder der Zuführfpflüge weist ein Bandförderelement auf, dessen ebene parallel zur Scharebene einer den Zuführfpflüge bildenden Schar ist. Das Bandförderelement weist eine Anzahl von rippenförmigen Vorsprüngen auf, die in Richtung zum Schleuderrad der Schneeschleuder bewegbar sind. Durch die Bandförderelemente soll ein Schneestau in einfacher und billiger Weise vor den Scharen vermieden werden.From EP 0 151 757 A2 a snow blower is arranged with the side of it Feed plows known. These feed plows serve to enlarge the cross section of the inlet the snow blower. A typical area of application for snow blowers is the use on airfields, where there is particularly high clearance and conveying speeds arrives. Each of the feed plows has a belt conveyor element, the plane parallel to the share plane of a share forming the feed plows. The belt conveyor element has a number of rib-shaped protrusions, which in the direction can be moved to the centrifugal wheel of the snow blower. Through the belt conveyor elements Snow congestion should be avoided in a simple and inexpensive manner in front of the coulters.

Der EP 0 151 757 A2 ist nichts über eine Anwendung der Schneeschleuder im Zusammenhang mit Half-Pipes entnehmbar oder über eine Bearbeitung einer Pistenoberfläche ausgesagt, während erfindungsgemäß durch Räumwerkzeuge einer Räumeinrichtung neben einer Materialverfrachtung quer zur Fahrtrichtung auch eine Pistenoberfläche einer Half-Pipe direkt bearbeitet werden kann. EP 0 151 757 A2 is not related to an application of the snow blower Removable with half pipes or by processing a slope surface testified while according to broaching tools of a broaching device in addition to material transversely to the direction of travel, also a slope surface a half pipe can be processed directly.

Vorzugsweise ist das am Pistenfahrzeug verstellbar gelagerte Arbeitsgeräte eine Fräse mit wenigstens einer Fräswelle. Durch diese Fräse kann der Half-Pipe-Kanal ausgefräst werden. Die Fräswelle kann beispielsweise über zwei gegenläufige Frässpiralen verfügen, durch die eine Schneeverfrachtung zur Mitte der Pistenpräpariervorrichtung hin erfolgt. Um dort angesammelten Schnee in einfacher Weise zu entfernen, weist die Pistenpräpariervorrichtung weiterhin eine der Fräse zugeordnete Schleudereinrichtung zum Verfrachten von durch die Fräse zugeführtem Schnee auf. Eine solche an sich bekannte Schleudereinrichtung weist ein den Frässpiralen zugeordnetes Schleuderrad auf, durch das der von den Frässpiralen zugeführte Schnee einem Auswurfkamin zugeführt und über diesen abgegeben wird. Durch entsprechende Ausrichtung des Auswurfkamins kann der Schnee aus der Half-Pipe entfernt oder einer anderen Stelle der Half-Pipe zur Ausbesserung oder dergleichen zugeführt werden. Entsprechende Antriebe und Getriebe für die Frässpiralen oder das Schleuderrad können in ihren Drehzahlen steuerbar sein, so daß diese je nach Schneeaufkommen in ihrer Leistung regulierbar sind. Außerdem kann durch die Drehzahl für das Schleuderrad die Wurfweite über den Auswurfkamin bestimmt werden.Preferably, the one mounted on the snow groomer is adjustable Tools a milling machine with at least one milling shaft. The half-pipe channel can be milled out using this router. The milling shaft can, for example, have two opposing ones Milling spirals, through which a snow shipment to In the middle of the slope grooming device. To accumulated there Removing snow in a simple way shows the Slope grooming device also one assigned to the tiller Centrifugal device for loading through the milling machine fed snow on. Such a known centrifugal device has one assigned to the milling spirals Centrifugal wheel through which the feed from the milling spirals Snow fed to and over an ejection chimney is delivered. By aligning the chute accordingly the snow can be removed from the half pipe or one elsewhere on the half pipe for repair or the like be fed. Corresponding drives and gears for the milling spirals or the centrifugal wheel can in their Speeds can be controlled so that they depend on the amount of snow are adjustable in their performance. In addition, by the speed for the centrifugal wheel the throwing distance over the discharge chimney be determined.

Insbesondere bei der Erstellung einer Half-Pipe oder bei einer großen Menge Neuschnee ist es von Vorteil, wenn die Räumwerkzeuge sich von der Pistenpräpariervorrichtung weg in Richtung eines Half-Pipe-Randes bewegen und mitgeführtes Material über diesen Rand aus der Half-Pipe entfernen. Ist eine solche Entfernung des Materials über den Rand durch die Räumwerkzeuge nicht oder nur schlecht möglich, ist eine Bewegung der Räumwerkzeuge zum Räumen der Half-Pipe-Seitenwände im wesentlichen in Richtung Fräse von Vorteil. Auf diese Weise erfolgt eine Verfrachtung des Schnees zur Fräse und von dort zur Schleudereinrichtung. Diese kann den Schnee aus der Half-Pipe entfernen.Especially when creating a half pipe or one large amount of fresh snow, it is advantageous if the clearing tools away from the slope grooming device Move in the direction of a half pipe edge and carry along the material Remove from the half pipe via this edge. Is a such removal of the material over the edge by the broaching tools a movement is not possible or only possible with difficulty the broaching tools for broaching the half-pipe sidewalls essentially an advantage in the direction of the milling machine. This is done a shift of the snow to the tiller and from there to the spinner. This can get the snow out of the half pipe remove.

Als Räumeinrichtung sind verschiedene Einrichtungen einsetzbar, solange diese über entsprechende Räumwerkzeuge verfügen, die zur Bearbeitung der Half-Pipe-Seitenwände entlang dieser beweglich sind. Bei einer einfachen Räumeinrichtung weist diese wenigstens eine Umlaufkette auf, von der eine Anzahl von Räumwerkzeugen in Richtung Pistenoberfläche, beziehungsweise Half-Pipe-Seitenwand abstehen. Eine solche Umlaufkette kann in einfacher Weise zur kontinuierlichen Bearbeitung der Half-Pipe verwendet werden.Various devices can be used as clearing devices, as long as they have appropriate broaching tools, to process the half pipe sidewalls along this are mobile. With a simple clearing device points this at least one circulation chain, of which a number of broaching tools in the direction of the slope surface, respectively Stand out half-pipe side wall. Such a circulation chain can be easily edited for continuous processing Half-pipe can be used.

Zur einfachen Lagerung der Umlaufkette sind am Seitenteil eine Anzahl von Rädern und/oder Rollen zur Führung der Umlaufkette drehbar gelagert. Um diese Räder oder Rollen ist die Umlaufkette herumgelegt und kann kontinuierlich bewegt werden. Die Räder oder Rollen können zumindest teilweise durch Gleitelemente ersetzt werden, welche die Umlaufkette abstützen.For easy storage of the circulating chain there are one on the side part Number of wheels and / or rollers for guiding the circulating chain rotatably mounted. This is around these wheels or castors Circulating chain and can be moved continuously. The wheels or rollers can at least partially through Sliding elements are replaced, which support the circulating chain.

Um die Umlaufkette in einfacher Weise zumindest im Bereich der Seitenwände der Half-Pipe entlang einer entsprechenden Kontur zu führen, ist die Umlaufkette an einer der Pitenoberfläche zuweisenden Pistenseite des Seitenteils durch eine Anzahl von Konturrädern/-rollen und/oder Kontor-Gleitelementen als Konturelementen entlang eines konvex gekrümmten Räumabschnitts geführt.Around the circulation chain in a simple way, at least in the area the side walls of the half pipe along a corresponding one Contouring is the circulation chain on one of the pit surfaces assigning slope side of the side part by a number of contour wheels / rollers and / or contour sliding elements as contour elements along a convexly curved broaching section guided.

Da der Räumabschnitt sich zumindest entlang der Seitenwände der Half-Pipe erstreckt, kann die Umlaufkette an den Enden des Räumabschnitts umgelenkt werden. Dazu sind an diesen Enden entsprechende Umlenkrollen - oder räder angeordnet. Since the clearing section extends at least along the side walls the half pipe extends, the circulation chain at the ends of the clearing section can be deflected. Do this at these ends appropriate pulleys - or wheels arranged.

Im einfachsten Fall ist eine erste Umlenkrolle benachbart zu einem Ende der Fräswelle talseitig zur Seitenwand der Half-Pipe und eine zweite Umlenkrolle an der Fräswelle oder der Fräse gegenüberliegendem Ende des Seitenteils angeordnet. Auf diese Weise ist sichergestellt, daß die Räumvorrichtung das mitgeführte Material bis in direkte Nachbarschaft zur Fräse transportiert.In the simplest case, a first deflection roller is adjacent to one end of the milling shaft on the valley side to the side wall of the half pipe and a second deflection roller on the milling shaft or Milling cutter arranged opposite end of the side part. On this ensures that the clearing device carried material right up to the milling machine transported.

Zum Antrieb der Umlaufkette ist es von Vorteil, wenn wenigstens eine der Konturrollen, Umlenkrollen oder eine separate Rolle als Antriebsrolle ausgebildet ist.To drive the circulation chain, it is advantageous if at least one of the contour rollers, deflection rollers or a separate one Role is designed as a drive roller.

Bei einem einfachen Ausführungsbeispiel für eine Antriebsrolle kann diese als verzahnte Rolle oder als Turras-Rad ausgebildet sein.In a simple embodiment for a drive roller can be designed as a toothed roller or as a Turras wheel be.

Um die Umlaufkette in einfacher Weise zu führen, kann die Antriebsrolle oberhalb der ersten Umlenkrolle angeordnet sein, wobei die Umlaufkette zwischen diesen Rollen einen im wesentlichen vertikalen Abhebeabschnitt und anschließend zwischen Antriebsrolle und zweiter Umlenkrolle einen Rücklaufabschnitt durchläuft. In dem Abhebeabschnitt kann noch von den Räumwerkzeugen mitgeführtes Material an die Fräse abgegeben werden.The drive roller can be used to guide the circulation chain in a simple manner be arranged above the first deflection roller, the orbital chain between these roles essentially one vertical lifting section and then between Drive roller and second guide roller a return section goes through. In the lifting section you can still remove the broaching tools carried material are given to the milling machine.

Im einfachsten Fall verlaufen die Drehachsen aller Rollen im wesentlichen parallel zur Fahrtrichtung des Pistenfahrzeugs, beziehungsweise zur Bewegungsrichtung der Pistenpräpariervorrichtung. Ebenso können beispielsweise die Drehachsen von Umlenkrollen und Konturrollen, beziehungsweise -rädern etwas geneigt in Fahrtrichtung nach oben verlaufen. Dadurch kann zwischen Umlaufkette und ersten Oberfläche ein entgegengesetzt zur Fahrtrichtung sich verengender Spalt gebildet sein, durch den beispielsweise vor der Pistenpräpariervorrichtung liegender Schnee einfacher der Räumvorrichtung zugeführt wird. In the simplest case, the axes of rotation of all rollers run in the essentially parallel to the direction of travel of the snow groomer, or the direction of movement of the slope grooming device. Likewise, for example, the axes of rotation of deflection rollers and contour rollers or wheels something run inclined in the direction of travel. This can between the chain and the first surface a narrowing gap to the direction of travel must be formed, for example in front of the slope grooming device lying snow more easily fed to the clearing device becomes.

Zur Vereinfachung der Konstruktion und zur Reduzierung der Kosten kann die Umlaufkette entlang des Rücklaufabschnitts abstützungsfrei geführt sein. Je nach Spannung der Umlaufkette durch die übrigen Rollen, beziehungsweise Räder hängt die Umlaufkette im Rücklaufabschnitt mehr oder weniger durch.To simplify the construction and reduce the The circulation chain along the return section can cost be guided without support. Depending on the tension of the circulating chain due to the other roles or wheels Circulation chain in the return section more or less through.

Um Half-Pipes mit unterschiedlichem Querschnitt herstellen und bearbeiten zu können, ist jedes Seitenteil gegenüber der Fräse im Arbeitswinkel verstellbar gelagert. Dabei kann die Verstellung für jedes Seitenteil separat erfolgen. Auf diese Weise können die Seitenwände der Half-Pipe unterschiedliche Steigungen aufweisen.To produce half pipes with different cross sections and being able to edit, each side part is opposite the The milling cutter is adjustable in the working angle. The Adjustment for each side part can be done separately. To this The side walls of the half pipe can be different Have slopes.

Bei einem einfachen Ausführungsbeispiel wird dies dadurch realisiert, daß das Seitenteil an einem Fräsrahmen zur Lagerung der Fräswelle lösbar befestigt und durch einen Stellzylinder zwischen Fräsrahmen und Seitenteil im Arbeitswinkel verstellbar ist. Durch die lösbare Befestigung kann anstelle eines Seitenteils mit Räumvorrichtung beispielsweise ein Seitenschild einseitig oder auch beidseitig zur Fräse angeordnet werden.In a simple embodiment, this will realized that the side part on a milling frame for storage the milling shaft releasably attached and by an actuating cylinder between the milling frame and the side part at the working angle is adjustable. The detachable attachment can be used instead a side part with a clearing device, for example a side plate arranged on one or both sides of the milling machine become.

Je nach Ausbildung der Fräse kann es von Vorteil sein, wenn die Seitenteile nicht direkt am Fräsrahmen befestigt sind. Dabei kann zwischen Fräsrahmen und Seitenteil ein Zwischenrahmen zur Lagerung und Verstellbarkeit des Seitenteils relativ zum Fräsrahmen, beziehungsweise zur Fräse angeordnet sein. Dieser Zwischenrahmen kann ebenso zwischen Seitenteil und Pistenfahrzeug angeordnet sein, wodurch die Seitenteile unabhängig zur Fräse gelagert und verstellbar sind.Depending on the design of the milling machine, it can be an advantage if the side parts are not attached directly to the milling frame. There can be an intermediate frame between the milling frame and the side part relative to the storage and adjustability of the side part arranged to the milling frame or to the milling machine be. This intermediate frame can also be between the side part and snow groomer can be arranged, whereby the side parts are stored and adjustable independently of the milling machine.

Um von der Räumvorrichtung mitgeführtes Material durch die Fräse sicher weiter zu transportieren, ist es günstig, wenn zumindest die Umlaufkette in Fahrtrichtung vor der Fräse angeordnet ist. In order to carry material carried by the clearing device through the It is convenient to transport the router safely, if at least the circulation chain in the direction of travel in front of the milling machine is.

Die Räumwerkzeuge können verschiedenste Formen aufweisen. In einem einfachen Fall sind die Räumwerkzeuge in der Umlaufkette integrierte Querstege. Ebenso können die Räumwerkzeug ähnlich zu Kettenstegen an den Ketten des Pistenfahrzeuges durch entsprechende Kettenstege an der Umlaufkette gebildet sein. Die Stege können sich über die gesamte Breite der Umlaufkette erstrecken. Bei einem anderen Ausführungsbeispiel sind die Räumwerkzeuge an der Umlaufkette lösbar befestigte Kratzelemente. Von diesen können beispielsweise mehrere in Breitenrichtung der Kette nebeneinander und/oder versetzt zueinander angeordnet sein.The broaching tools can have a wide variety of shapes. In The broaching tools in the circulation chain are a simple case integrated crossbars. Likewise, the broach can be similar to chain stays on the chains of the snow groomer Corresponding chain links are formed on the circulating chain. The webs can span the entire width of the circulating chain extend. In another embodiment, the Broaching tools detachably attached to the circulating chain. For example, several of these can be in the width direction the chain side by side and / or offset from each other be arranged.

In diesem Zusammenhang kann es weiterhin von Vorteil sein, wenn die Arbeitstiefe der Räumwerkzeuge in Fahrtrichtung abnimmt. Dadurch wird die Pistenoberfläche im Bereich der Seitenwände der Half-Pipe zuerst durch Räumwerkzeuge mit geringerer Arbeitstiefe und anschließend durch Räumwerkzeuge mit größerer Arbeitstiefe bearbeitet. Bei Querstegen kann dabei die Arbeitstiefe kontinuierlich entgegengesetzt zur Fahrtrichtung zunehmen.In this context, it can still be advantageous when the working depth of the broaching tools decreases in the direction of travel. As a result, the slope surface is in the area of the side walls the half pipe first with broaching tools with less Working depth and then with broaching tools processed greater working depth. With crossbars can the working depth continuously opposite to the direction of travel increase.

Um eine durch die Räumwerkzeuge gegebenenfalls aufgerauhte Pistenoberfläche der Seitenteile der Half-Pipe einfach wieder einzuebnen, kann das Seitenteil zum Glätten der Pistenoberfläche ein der Umlaufkette in Fahrtrichtung nachgeordnetes Glätteschild aufweisen. Dieses kann sich direkt an die Umlaufkette mit ihren Räumwerkzeugen anschließen, wobei Räumeinrichtung und Glätteschild an einem Rahmen angeordnet sein können.To a roughened, if necessary, by the broaching tools Slope surface of the side parts of the half pipe simply again level the side part to smooth the slope surface one downstream of the circulation chain in the direction of travel Have a smoothing label. This can be directly related to the circulation chain connect with their broaching tools, whereby broaching device and smoothing plate can be arranged on a frame can.

Um eine Kurvenfahrt des Pistenfahrzeuges in der Half-Pipe zu vereinfachen und/oder die Pistenpräpariervorrichtung unterschiedlich breiten Abschnitten der Half-Pipe anzupassen, können die Seitenteile quer zur Fahrtrichtung ausfahrbar gelagert sein. Ebenso kann eine gesamte seitliche Verstellung von Arbeitsgerät mit Seitenteilen durch eine gemeinsame seitliche Verstellung erzielt werden. To corner the snow groomer in the half-pipe simplify and / or the slope grooming device differently wide sections of the half pipe the side parts are mounted extendable transversely to the direction of travel be. Likewise, an entire lateral adjustment of Tool with side parts by a common side Adjustment can be achieved.

Um beispielsweise die Räumeinrichtungen je nach Arbeitsaufkommen an beiden Seitenteilen separat zu steuern, kann jeder Antriebsrolle ein separater, insbesondere elektrischer, Antrieb zugeordnet sein.For example, the clearing facilities depending on the workload Everyone can control separately on both sides Drive roller a separate, in particular electrical, drive be assigned.

Zur Verkleidung der Seitenteile und der Fräse können entsprechende Verkleidungen oder Gehäuse vorgesehen sein. Durch eine entsprechende Form dieser Verkleidung oder Gehäuse kann vor diesem aufgestauter Schnee beispielsweise der Fräse zugeführt werden.Corresponding can be used to cover the side parts and the router Cladding or housing may be provided. By a appropriate form of this cladding or housing can be before this snow, for example, fed to the milling machine become.

Im folgenden wird ein vorteilhaftes Ausführungsbeispiel der Erfindung anhand der in der Zeichnung beigefügten Figuren näher erläutert und beschrieben.In the following an advantageous embodiment of the Invention with reference to the accompanying figures in the drawing explained and described.

In Figur 1 ist ein Pistenfahrzeug 3 mit einer an dessen Vorderseite ange ordneter Pistenpräpariervorrichtung 1 in Vorderansicht dargestellt. Die Pistenpräpariervorrichtung 1 umfaßt eine Fräse 11 als Arbeitsgerät 4, eine Schleudereinrichtung 13 und zwei seitlich zur Fräse 11 angeordnete Seitenteile 6 und 7.In Figure 1 is a snow groomer 3 with one on the front arranged piste grooming device 1 in front view shown. The slope grooming device 1 comprises a milling machine 11 as an implement 4, a centrifugal device 13 and two side parts arranged laterally to the milling cutter 11 6 and 7.

Die Fräse 11 weist eine aus zwei Abschnitten mit gegenläufigen Frässpiralen 34 und 35 gebildete Fräswelle 12 auf, die in einem entsprechenden Fräsrahmen 30 drehbar gelagert ist. Eine Arbeitsbreite der Fräswelle 11 entspricht im wesentlichen einem flachen Bodenteil einer Half-Pipe 2. An diesen Bodenteil schließen sich beidseitig nach oben gekrümmte Seitenwände 5 der Half-Pipe an. Die Seitenteile 6, 7 liegen auf einer durch die Seitenwände 5 gebildeten Pistenoberfläche 15 an.The milling cutter 11 has one of two sections with opposite directions Milling spirals 34 and 35 formed milling shaft 12, which in a corresponding milling frame 30 is rotatably mounted. A Working width of the milling shaft 11 corresponds essentially to one flat bottom part of a half pipe 2. To this bottom part close upward curved side walls 5 on both sides the half pipe. The side parts 6, 7 are on one the side walls 5 formed slope surface 15.

Die Pistenpräpariervorrichtung 1 ist in Fahrtrichtung 8 vor dem Pistenfahrzeug 3 angeordnet und mit diesem über einen entsprechenden, nicht dargestellten Rahmen verbunden.The slope grooming device 1 is in the direction of travel 8 the snow groomer 3 arranged and with this over a corresponding frame, not shown connected.

Zwischen Pistenfahrzeug 3 und Fräse 11 ist ein Schleudereinrichtung 13 mit einem Auswurfkamin angeordnet, der in Figur 1 vor einer Frontscheibe des Pistenfahrzeuges sichtbar ist. Die Schleudereinrichtung 13 umfaßt ein Schleuderrad 36, das in Fahrtrichtung 8 hinter der Fräse 11 und im wesentlichen in deren Mitte angeordnet ist.A centrifugal device is located between snow groomer 3 and milling machine 11 13 arranged with an ejection chimney, which in FIG is visible in front of a front window of the snow groomer. The Spinner 13 includes a spinner 36 which in Driving direction 8 behind the milling machine 11 and essentially in the middle of which is arranged.

In Figur 2 ist die erfindungsgemäße Pistenpräpariervorrichtung 1 vergrößert und ohne Verkleidungen oder Gehäuse in einer Vorderansicht dargestellt. Gleiche Bezugszeichen kennzeichnen gleiche Teile und werden nur noch teilweise erwähnt.In Figure 2 is the slope grooming device according to the invention 1 enlarged and without panels or housing in one Shown front view. Identify the same reference symbols same parts and are only partially mentioned.

Die Seitenteile 6 und 7 der Pistenpräpariervorrichtung 1 weisen Räumeinrichtungen 10 mit einer Anzahl von Räumwerkzeugen 9 auf. Jede Räumeinrichtung 10 ist durch eine Umlaufkette 14 gebildet, von der die einzelnen Räumwerkzeuge im wesentlichen senkrecht abstehen. Die Umlaufkette 14 ist über eine Vielzahl von Rädern oder Rollen 16 geführt. Auf einer Pistenseite 17 der Seitenteile 6, 7 sind die entsprechenden Rollen 16 als Konturrollen 18 ausgebildet, durch die die Umlaufkette 14 in einer für die Seitenwände der Half-Pipe, siehe Figur 1, erwünschten Kontur abgestützt ist. Durch diese Konturrollen 18 wird ein Räumabschnitt 19 bestimmt, in dem die einzelnen Räumwerkzeuge 19 Material von der Pistenoberfläche der Half-Pipe abräumen. An Enden 20 und 21 des Räumabschnitts 19 sind Umlenkrollen 22, beziehungsweise 23 angeordnet, die im Vergleich zu den Konturrollen 18 einen größeren Durchmesser aufweisen. Eine erste Umlenkrolle 22 ist benachbart zu einem Ende 24 der Fräse 11, beziehungsweise der Fräswelle 12 angeordnet. Eine zweite Umlenkrolle 23 ist an einem der Fräse 11 gegenüberliegenden Ende 25 des Seitenteils 6 und ebenso des Seitenteils 7 angeordnet.The side parts 6 and 7 of the slope preparation device 1 have Broaching devices 10 with a number of broaching tools 9 on. Each clearing device 10 is connected by a circulating chain 14 formed, of which the individual broaching tools essentially protrude vertically. The circulating chain 14 is of a variety guided by wheels or rollers 16. On a slope side 17 the side parts 6, 7 are the corresponding rollers 16 as Contour rollers 18 are formed, through which the circulating chain 14 in one desired for the side walls of the half pipe, see FIG. 1 Contour is supported. Through these contour rollers 18 a clearing section 19 is determined in which the individual Broaching tools 19 Material from the slope surface of the half pipe clear away. At ends 20 and 21 of the broaching section 19 are Deflecting rollers 22, 23 respectively, which are compared to the contour rollers 18 have a larger diameter. A first deflection roller 22 is adjacent to one end 24 of the milling cutter 11, or the milling shaft 12. A second deflection roller 23 is on one of the milling cutters 11 opposite End 25 of the side part 6 and also the Side part 7 arranged.

Durch die erste Umlenkrolle 22 ist die Umlaufkette 14 im wesentlichen in Vertikalrichtung nach oben umgelenkt. Benachbart zum Ende 24 der Fräse 11 durchläuft die Umlaufkette 14 einen Abhebeabschnitt 27, in dem sie von der Pistenoberfläche abgehoben wird.Through the first deflection roller 22, the circulating chain 14 is essentially deflected upwards in the vertical direction. Adjacent at the end 24 of the milling cutter 11 passes through the circulating chain 14 a lift-off section 27, in which it extends from the slope surface is lifted off.

Am Ende des Abhebeabschnitts 27 ist eine mit einem Antrieb 33 versehene Antriebsrolle 26 angeordnet, die in dem dargestellten Ausführungsbeispiel als Stachelwalze ausgebildet ist. Durch die Antriebsrolle 26 wird die Umlaufkette 14 von der Fräse 11 weggeführt und durchläuft bis zur zweiten Umlenkrolle 23 einen Rücklaufabschnitt 28. In diesem sind keine weiteren Rollen zur Abstützung der Umlaufkette angeordnet, so daß diese in dem Rücklaufabschnitt je nach Kettenspannung durchhängen kann.At the end of the lifting section 27 is one with a drive 33 provided drive roller 26 arranged in the illustrated Embodiment is designed as a spiked roller. By the drive roller 26, the circulating chain 14 of the Router 11 led away and runs up to the second deflection roller 23 a return section 28. There are no further ones in this section Rollers arranged to support the circulating chain, so that they sag in the return section depending on the chain tension can.

Bei dem dargestellten Ausführungsbeispiel bewegt sich die Umlaufkette 14 in Bewegungsrichtung 37, das heißt von der zweiten Umlenkrolle 23 zur ersten Umlenkrolle 22 in Richtung Arbeitsgerät 4. Auf diese Weise wird Schnee von den Seitenwänden der Half-Pipe, siehe Figur 1, in Richtung zur Fräse 11 abgeräumt.In the illustrated embodiment, the circulating chain moves 14 in the direction of movement 37, that is, from the second Deflection roller 23 to the first deflection roller 22 in the direction of the implement 4. In this way, snow from the side walls the half pipe, see FIG. 1, in the direction of the milling cutter 11 cleared.

Alle Rollen, beziehungsweise Räder der Seitenteile 6, 7 sind an diesen um Drehachsen 29 drehbar gelagert, wobei die Drehachsen parallel zur Fahrtrichtung 8 verlaufen.All roles, or wheels of the side parts 6, 7 are on these rotatably mounted about axes of rotation 29, the axes of rotation run parallel to the direction of travel 8.

Durch die Höhe der Räumwerkzeuge 9 wird deren Arbeitstiefe 32 bestimmt, bis zu der die Räumwerkzeuge in die Pistenoberfläche eingreifen können. The working depth 32 becomes 32 by the height of the broaching tools determined up to which the broaching tools in the slope surface can intervene.

Zur Verstellung der Seitenteile und damit zur Veränderung ihres Arbeitswinkels, sind die Seitenteile 6, 7 über Stellzylinder 31 mit dem Fräsrahmen 30 der Fräse 11 verbunden. Je nach Betätigung der Stellzylinder 31 sind die Enden 25 der Seitenteile 6, 7 mehr oder weniger hoch über der Fräse 11 angeordnet, wodurch sich die durch die Unterseite der Pistenpräpariervorrichtung 1 bestimmte Kontur ändert.To adjust the side parts and thus to change their Working angle, the side parts 6, 7 are via actuating cylinders 31 connected to the milling frame 30 of the milling machine 11. Each after actuation of the actuating cylinder 31, the ends 25 of the Side parts 6, 7 arranged more or less high above the milling cutter 11, which extends through the underside of the slope grooming device 1 specific contour changes.

In der Regel sind die Seitenteile 6, 7 in Fahrtrichtung 8 vor dem entsprechenden Arbeitsgerät 4 angeordnet, damit durch die Räumeinrichtungen 10 von Seitenwänden der Half-Pipe abgeräumtes Material vollständig dem Arbeitsgerät zugeführt werden kann.As a rule, the side parts 6, 7 are in the direction of travel 8 the corresponding implement 4 arranged so that by the Clearing devices 10 cleared from side walls of the half pipe Material are completely fed to the implement can.

Zur Vereinfachung der Darstellung sind weitere Stelleinrichtungen zur seitlichen Verstellung der Seitenteile 6, 7 gegenüber dem Arbeitsgerät 4, beziehungsweise zur gemeinsamen seitlichen Verstellung der gesamten Pistenpräpariervorrichtung gegenüber dem Pistenfahrzeug nach Figur 1 nicht dargestellt.To simplify the illustration, there are additional control devices for the lateral adjustment of the side parts 6, 7 opposite the implement 4, or for common lateral adjustment of the entire slope grooming device not shown compared to the snow groomer of Figure 1.

Figur 3 zeigt für ein rechtes Seitenteil 7 nach Figur 2 ein weiteres Ausführungsbeispiel. Gleiche Teile sind durch gleiche Bezugszeichen versehen und werden nur noch teilweise erwähnt.FIG. 3 shows a right side part 7 according to FIG further embodiment. The same parts are the same Provide reference numerals and are only partially mentioned.

Im Unterschied zu dem Ausführungsbeispiel nach Figur 2 weist die Umlaufkette 14 nach Figur 3 als Räumwerkzeuge 9 Querstege bzw. Kettenstege auf, die an der Umlaufkette lösbar befestigt sein können. Im Bereich des Räumabschnitts 19 ist die Umlaufkette 14 zwischen einer als Antriebsrolle 26 ausgebildeten, einem Ende 24 der Frässpirale 25 benachbarten Rolle 16 und einer Umlenkrolle 23 über Kontur-Gleitelemente 38 geführt. Diese weisen entsprechend der Kontur der Halfpipe-Seitenwände eine konvexe Krümmung auf. In contrast to the embodiment of Figure 2 points the circulating chain 14 according to Figure 3 as broaching tools 9 crossbars or chain stays, which are releasably attached to the circulating chain could be. In the area of the clearing section 19 is the circulating chain 14 between a drive roller 26, one end 24 of the milling spiral 25 adjacent roller 16 and a deflection roller 23 guided over contour sliding elements 38. These point in accordance with the contour of the half pipe side walls a convex curvature.

Von der Umlenkrolle 23 wird die Umlaufkette 14 im wesentlichen gradlinig und über ein weiteres Gleitelement 38 zur Antriebsrolle 26 zurückgeführt. Dieses Gleitelement wie auch die übrigen Kontur-Gleitelemente 38 können verstellbar und/oder verschwenkbar an einem entsprechenden Rahmen des Seitenteils 7 gelagert sein. In diesem Fall sind die Gleitelemente 38 über Tragarme 42, 43 an einem zwischen den beiden Drehachsen 29 von Umlenkrolle 23 und Antriebsrolle 26 sich erstreckendem Träger 40 gelagert. Dieser ist an seinem der Drehachse 29 der Antriebsrolle 26 zugeordneten Ende relativ zum Fräsraum 30 verschwenkbar gelagert. Ein weiterer Träger 41 erstreckt sich zwischen einem Anlenkpunkt 44 am Fräsrahmen 30 und der Drehachse 29 der Umlenkrolle 23. Zwischen dem Träger 41 und dem Fräsrahmen 30 ist zur Verstellung des Seitenteils 7 der Stellzylinder 31 angeordnet.From the deflection roller 23, the circulation chain 14 is essentially straight and via a further sliding element 38 to the drive roller 26 returned. This sliding element as well the other contour sliding elements 38 can be adjusted and / or pivotable on a corresponding frame of the Be part 7 stored. In this case, the sliding elements 38 via support arms 42, 43 on one between the two Axes of rotation 29 of deflection roller 23 and drive roller 26 themselves extending support 40 stored. This is at his the Axis of rotation 29 of the drive roller 26 associated end relatively pivoted to the milling space 30. Another carrier 41 extends between a pivot point 44 on the milling frame 30 and the axis of rotation 29 of the deflection roller 23. Between the carrier 41 and the milling frame 30 is for adjusting the side part 7 of the actuating cylinder 31 arranged.

Es sei angemerkt, daß beispielsweise eins der Kontur-Gleitelemente auch durch entsprechende Konturräder/-rollen nach Figur 2 ersetzbar ist.It should be noted that, for example, one of the contour sliding elements also with appropriate contour wheels / rollers according to Figure 2 is replaceable.
