Description

Die vorliegende Erfindung bezieht sich auf eine Schaufel - Greifer-Materialbewegungseinheit, insbesondere für Schnee, gemäß dem Oberbegriff des Anspruches 1.The present invention relates to a shovel-gripper material movement unit, in particular for snow, according to the preamble of claim 1.

Allgemein bekannt ist, Materialien, z.B. Schnee, von Flä­chen abzuräumen, wobei an Selbstfahrzeugen angebrachte Schaufeln verwendet werden, wie z.B. bei den sogenannten Schneekatzen, um die Materialien in eine Sammelstelle zu schieben, wobei so die Fläche befreit oder geebnet wird. Die Verwendung dieser Schaufeln ist ohne weiteres bequem, vor allem, weil sie in ihrer Breite über die größte Brei­te des Selbstfahrzeuges ragen, wobei so eine vom Selbst­fahrzeug selbst schon befahrbare Spur geschaffen wird. Es besteht jedoch das Problem, daß das abzuräumende Material nur in außerhalb der Spur liegende Stellen geschoben wer­den kann, wo schon anderes Material abgelagert wurde oder wo das Material unbenutzt liegt.It is well known that materials, e.g. Snow to be cleared of surfaces using shovels attached to self-vehicles, e.g. with the so-called snow cats to push the materials into a collection point, thus clearing or leveling the area. The use of these blades is straightforward, above all because their width extends beyond the greatest width of the self-vehicle, thus creating a lane that the self-vehicle itself can drive on. However, there is the problem that the material to be cleared can only be pushed into locations outside the track, where other material has already been deposited or where the material is unused.

Es ist überdies bekannt, Greifer zur Aufnahme von abzu­räumenden Material zu verwenden und dieses in gewünsch­ten, auch von der befreiten Spur entfernten Orten zu transportieren. In diesem Fall ist die Breite des Grei­fers üblicherweise sehr geringer als die Breite des Selbstfahrzeuges und somit muß das abzuräumende Material in mehreren Arbeitsgängen aufgeladen werden, um die freie Piste zu schaffen. Das Material selbst wird überdies im Greifer aufgrund der auf das Material ausgeübten Druck­kräften übermäßig verdichtet.It is also known to use grippers to pick up material to be cleared and to transport it to desired locations that are also removed from the cleared track. In this case, the width of the grapple is usually very small than the width of the self-vehicle and thus the material to be cleared has to be loaded in several work steps to create the free slope. The material itself is also excessively compressed in the gripper due to the compressive forces exerted on the material.

Eine der Aufgaben der vorliegenden Erfindung liegt daher darin, eine Lösung vorzuschlagen, die es ermöglicht, eine möglichst breite Piste und eine möglichst große Material­ladung zu erreichen, um das Material leicht an den gewün­schten Ort bringen zu können.One of the objects of the present invention is therefore to propose a solution which makes it possible to achieve the widest possible slope and the greatest possible load of material in order to be able to bring the material easily to the desired location.

Eine weitere Aufgabe der Erfindung liegt darin, ein Lade­system zu finden, das möglichst wenig auf die Merkmale des Materials, vor allem von Schnee, Einfluß übt, um das Material mit einem Höchstmaß an Gleichförmigkeit an Stel­len zu verteilen, wo es erwünscht ist, z.B. im Falle des Schnees, um die Schneepisten bei Schneemangel zu präpa­rieren.Another object of the invention is to find a loading system which has as little influence as possible on the characteristics of the material, especially snow, in order to distribute the material with maximum uniformity in places where it is desired, e.g. in the case of snow, to prepare the snow slopes in the absence of snow.

Diese und weitere Aufgaben werden erfindungsgemäß durch den kennzeichnenden Teil des Anspruchs 1 gelöst.These and other objects are achieved according to the invention by the characterizing part of claim 1.

Es ist erkennbar, daß aufgrund des erfinderischen Gedan­kens alle beschriebenen Vorteile einer Schaufel mit den Vorteilen eines Greifers kombiniert werden. Mittels des Greifers ist es nämlich möglich, das Material längs einer Breite zu verschieben, die über die Breite des Selbst­fahrzeuges vorragt, um das Material in Richtung des Grei­fers zu leiten, der zusammen mit der Schaufel ohne über­mäßige Druckkräfte das Material aufnimmt, um dieses bei Beendigung der Ladearbeit an eine Abladestelle zu brin­gen.It can be seen that, on the basis of the inventive idea, all of the described advantages of a bucket are combined with the advantages of a gripper. By means of the gripper, it is in fact possible to move the material along a width which projects beyond the width of the self-vehicle in order to guide the material in the direction of the gripper, which, together with the shovel, picks up the material without excessive pressure forces, so that it ends bring the loading work to an unloading point.

Weitere Einzelheiten und Merkmale der erfindungsgemäßen Schaufel-Greifer-Einheit gehen noch klarer aus der fol­genden Beschreibung eines bevorzugten Ausführungsbeispie­les unter Bezugnahme auf die beigelegte Zeichnung hervor.Further details and features of the shovel-gripper unit according to the invention can be seen even more clearly from the following description of a preferred exemplary embodiment with reference to the accompanying drawing.

  • Figur 2 eine Vorderansicht gemäß Pfeil A aus Figur 1, je­doch nur des Greifers mit dem entsprechenden Hal­ter, und

Show in the drawing
  • FIG. 1 schematically shows a side view of a shovel-gripper unit attached to the self-vehicle with suspension,
  • Figure 2 is a front view according to arrow A from Figure 1, but only the gripper with the corresponding holder, and
  • Figure 3 shows one of the holder of the gripper on the blade, in an enlarged front view.

Wie in Figur 1 dargestellt, ist an einem Selbstfahrzeug, z.B. Raupenfahrzeug, in 1 schematisch dargestellt, mit­tels einer Dreipunktaufhängung in 2, 3 und 4 eine, ins­gesamt mit dem Bezugszeichen 5 dargestellte Schaufel an­gebracht. Auf bekannte Weise ist die Schaufel 5 durch ei­nen hydraulischen Zylinder 6 anhebbar und absenkbar, der jeweils in 2 bzw. 7 um die durch die Gelenkspunte 3, 4 festgelegte Achse verschwenkbar angelenkt ist. Die Schau­fel 5 ist überdies durch Einwirkung eines zwischen seinem Halter 8 und der Schaufel 5 gespannten, hydraulischen Zy­linders 9 um dem Halter 8, senkrecht zur Achse 3, 4 ver­schwenkbar. Die bis jetzt beschriebenen Einzelheiten ge­hören dem Stand der Technik an und werden daher nicht näher erläutert, da sie dem Fachmann wohl bekannt sind.As shown in Figure 1, a self-vehicle, e.g. The caterpillar vehicle, shown schematically in FIG. 1, has a three-point suspension in FIGS. 2, 3 and 4 attached to a blade, shown overall with the reference number 5. In a known manner, the blade 5 can be raised and lowered by a hydraulic cylinder 6, which is articulated in each case in 2 or 7 about the axis defined by the articulation points 3, 4. The blade 5 can moreover be pivoted by the action of a hydraulic cylinder 9 stretched between its holder 8 and the blade 5 around the holder 8, perpendicular to the axis 3, 4. The details described so far belong to the prior art and are therefore not explained in detail since they are well known to the person skilled in the art.

Erfindungsgemäß weist die Schaufel 5 zwei Halter bzw. Stützelemente 10 (von denen eines nicht gezeigt ist) auf, die sich in zueinanader parallelen, vertikalen Ebenen auf der Hinterfläche der Schaufel 5 bis zum oberen Rand der­ selben erstrecken und jeweils einen im wesentlichen be­cherförmigen Teil 11 eines Halters 12 aufnehmen. Der Bo­den eines jeden der beiden becherförmigen Teile 11 ist durch jeweils eine Schraube 13 am oberen Ende eines jeden Stützelementes 10 befestigt. Der becherförmige Teil 11 ist in Richtung seiner Öffnung derart ausgeweitet, daß eine Selbstzentrierung desselben am oberen Ende des Stützelementes 10 hervorgerufen wird, wenn der Halter 11 reiterartig um den oberen Rand der Schaufel 5 angebracht wird. Wie mehr aus Figur 3 hervorgeht, besteht jeder Hal­ter 12 aus einem Doppelflansch 14, 15, wobei jeder Flan­sch sich in den erwähnten vertikalen Ebenen erstreckt, und aus einer Platte 16, mit der die Flansche 14 und 15 rechtwinklig verschweißt sind und die an ihrem oberen Ende den becherförmigen Teil 11 trägt. Das untere Ende der Platte 16 erstreckt sich hingegen, immer in der Ebene der Platte selbst, in eine Lasche 17, die eine Bohrung 18 aufweist, um den gesamten Halter 12 durch jeweils eine Schraube 39 an einem mit der Vorder- bzw. Arbeitsfläche der Schaufel 5 festliegenden Winkel 20 befestigt zu wer­den. Vorteilhafterweise sind immer zwei Halter 12 unter­einander mittels eines Verbindungsrohres 22 verbunden, das sich parallel zum oberen Rand der Schaufel 5 derart erstreckt, daß eine konstruktive Einheit gebildet wird.According to the invention, the blade 5 has two holders or support elements 10 (one of which is not shown), which are located in mutually parallel, vertical planes on the rear surface of the blade 5 up to the upper edge of the extend the same and each receive a substantially cup-shaped part 11 of a holder 12. The bottom of each of the two cup-shaped parts 11 is fastened by a screw 13 at the upper end of each support element 10. The cup-shaped part 11 is widened in the direction of its opening in such a way that its self-centering is brought about at the upper end of the support element 10 when the holder 11 is mounted like a rider around the upper edge of the blade 5. As can be seen more from Figure 3, each holder 12 consists of a double flange 14, 15, each flange extending in the vertical planes mentioned, and a plate 16 to which the flanges 14 and 15 are welded at right angles and which are on their upper End carries the cup-shaped part 11. The lower end of the plate 16, on the other hand, extends, always in the plane of the plate itself, into a tab 17, which has a bore 18, around the entire holder 12, each with a screw 39 on one with the front or working surface of the blade 5 fixed angles 20 to be attached. Advantageously, two holders 12 are always connected to one another by means of a connecting tube 22 which extends parallel to the upper edge of the blade 5 in such a way that a structural unit is formed.

Wie aus Figur 1 ersichtlich, ragt der Doppelflansch 14, 15 nach vorne vor und nimmt in seinen Aufnahmen 19 je­weils einen Drehbolzen 21 auf, der jeweils ein Eckblech 23 trägt, das zwischen den Flanschen 14 und 15 in einer im wesentlichen zur Breiterstreckung der Schaufel 5 senk­rechten Richtung drehbar ist. Jedes Eckblech 23 trägt im Bereich seines oberen Randes, mit ihm fest verbunden, eine im wesentlichen viertelkreisförmige Seitenwand 24 eines Greifers 25, dessen Boden 26 sich längs dieses Viertelkreises erstreckt.As can be seen from FIG. 1, the double flange 14, 15 protrudes forward and receives in its receptacles 19 a pivot pin 21, each of which carries a corner plate 23, which extends between the flanges 14 and 15 in a manner essentially extending the blade 5 vertical direction is rotatable. Each corner plate 23 carries in the area of its upper edge, firmly connected to it, a substantially quarter-circular side wall 24 of a gripper 25, the bottom 26 of which extends along this quarter circle.

Der Doppelflansch 14, 15 erstreckt sich überdies nach oben, wo er mit einem Bolzen 27 versehen ist, an dem je­weils ein hydraulischer Zylinder 28 angelenkt ist, dessen Kolbenstange 29 mit ihrem freien Ende in 30 mit dem Eck­blech 23 mit Abstand vom Drehbolzen 21 verschwenkbar an­greift, so daß der Greifer 25 von einer abgesenkten Stel­lung, wo der untere Rand 31 im wesentlichen parallel zum unteren Rand der Schaufel 5 liegt, in eine angehobene Stellung (in Figur 1 gestrichelt eingezeichnet) ver­schwenkt werden kann, wo der Boden 26 des Greifers 25 um etwa 90°, bzw. darüber, um die erwähnte erste Stellung verschwenkt ist.The double flange 14, 15 also extends upwards, where it is provided with a bolt 27 to which a hydraulic cylinder 28 is articulated, the piston rod 29 of which engages with its free end in 30 with the corner plate 23 so as to be pivotable at a distance from the pivot pin 21 , so that the gripper 25 can be pivoted from a lowered position, where the lower edge 31 is essentially parallel to the lower edge of the bucket 5, into a raised position (shown in dashed lines in FIG. 1), where the bottom 26 of the gripper 25 about 90 °, or above, is pivoted about the first position mentioned.

Wie erkennbar, kann aufgrund von zwei einzigen Befesti­gungsschrauben 13 und 39 für jeden Halter 10 und 20 der gesamte Greifer rasch, einfach und leicht "reiterartig" an der Schaufel 5 angebracht werden. Die Montage wird überdies durch die mittels der becherförmigen Teile 11 erzielten Selbstzentrierung erleichtert.As can be seen, the entire gripper can be attached to the blade 5 quickly, simply and easily in a “rider-like” manner on account of two single fastening screws 13 and 39 for each holder 10 and 20. The assembly is also facilitated by the self-centering achieved by means of the cup-shaped parts 11.

Die Wirkungsweise der erfindungsgemäßen Schaufel-Greifer­einheit ist wie folgt:The action of the bucket gripper unit according to the invention is as follows:

Beispielsweise stelle man sich vor, eine Schneepiste zu räumen oder zu öffnen. Wird der Schnee mittels der Schau­fel 5 mit dem in der gestrichelt gezeichneten Stellung angehobenen Greifer 26 gemäß Pfeil V verschoben, so wird der Schnee selbst in einem gewissen Sinne nach oben "gehobelt". Die so erhaltene Schneeschicht wird quasi spanförmig in Richtung des Greifers 25 in die angehobenen Stellung geführt. Am Boden 26 angekommen, wird der Schnee angehalten und mit progressiver Füllung des Greifers 25 wird dieser in die Transportstellung abgesenkt, in der der Schnee zwischen dem Boden 26 und der Vorderfläche der Schaufel 5 angehäuft bleibt. Es liegt nahe, daß dem Grei­fer 25 auch Schnee zugeführt werden kann, der sich außer­halb der größten Breite des Greifers sebst befindet: die Schaufel, auf bekannte Weise breiter als der Greifer, ist nämlich imstande, mit ihren in Schubrichtung der Schaufel geneigten Außenabschnitten den Schnee in Richtung des Greifers selbst zu schieben. Der so angesammelte Schnee wird nur in einem Mindestmaß verdichtet und kann mit Vor­teil zum Präparieren von Schneepisten verwendet werden.For example, imagine clearing or opening a snow slope. If the snow is moved by means of the shovel 5 with the gripper 26 raised in the position shown in dashed lines according to arrow V, the snow itself becomes upward in a certain sense "planed". The layer of snow thus obtained is guided in a quasi-chip shape in the direction of the gripper 25 into the raised position. Arrived at the bottom 26, the snow is stopped and with progressive filling of the gripper 25, it is lowered into the transport position in which the snow remains piled between the bottom 26 and the front surface of the shovel 5. It is obvious that the gripper 25 can also be supplied with snow which is located outside the greatest width of the gripper itself: the shovel, which is known to be wider than the gripper, is capable of the snow with its outer sections inclined in the direction of thrust of the shovel to push towards the gripper itself. The snow accumulated in this way is only compressed to a minimum and can advantageously be used to prepare snow slopes.

Ohne weiters können an der beschriebenen Schaufel-Grei­fereinheit verschiedene Abänderungen und Varianten vorge­nommen werden, ohne den Schutzbereich der vorliegenden Erfindung zu verlassen: so könnte die Anzahl der hydrau­lischen Zylinder, der Verbindungshalter Schaufel-Greifer, der Befestigungssysteme derselben usw. je nach Bedarf ge­wählt werden. Anstatt der hydraulischen Zylinder könnten auch andere Betätigungsmittel, wie z.B. pneumatischer Art usw. verwendet werden.Various modifications and variants can also be made to the bucket gripper unit described without departing from the scope of the present invention: the number of hydraulic cylinders, the bucket gripper connection holder, the fastening systems thereof, etc. could be selected as required. Instead of the hydraulic cylinders, other actuating means, such as pneumatic type, etc. can be used.
