Description

Die vorliegende Erfindung betrifft eine Abstützplatte, welche lösbar mit einem Abstützzylinder verbindbar ist. Solche Abstützplatten werden bei einer Vielzahl von Geräten wie z. B. Mobilkränen, Reachstackern, Baggern und anderen Umschlaggeräten eingesetzt, welche über Abstützzylinder in ihrer Arbeitsposition abgestützt werden. Die Abstützplatten sorgen für einen sicheren Stand der Geräte sowie dafür, dass ein maximal zulässiger Bodendruck nicht überschritten wird.The present invention relates to a support plate which is detachably connectable to a support cylinder. Such support plates are used in a variety of devices such. As mobile cranes, Reachstackern, excavators and other handling equipment used, which are supported by supporting cylinders in their working position. The support plates ensure a safe stand of the devices as well as that a maximum permissible ground pressure is not exceeded.

Bekannte Abstützplatten aus Kunststoff werden üblicherweise über zwei Steckbolzen am Abstützkopf des Abstützzylinders befestigt, während Stahlabstützplatten üblicherweise einen Verriegelungsmechanismus mit Schiebe- und Bolzverbindungen aufweisen. Diese Verriegelungsmechanismen zwischen Abstützplatte und Abstützzylinder sind aber relativ schwer, teuer und kompliziert. Zudem weisen sie Teile wie z. B. die Schiebebolzen auf, welche verloren gehen können. Dabei ist die Montage und Demontage der Abstützplatten kompliziert, weil der Abstützkopf erst hydraulisch in eine Aufnahmepfanne an der Abstützplatte gefahren werden muss, um dann in dieser Position manuell verriegelt zu werden. Außerdem ist der Verdrehwinkel zwischen Abstützzylinder und Abstützplatte durch die Steckbolzen bzw. den Verriegelungsmechanismus stark eingeschränkt.Known plastic support plates are usually attached via two locking pins on the support head of the support cylinder, while Stahlabstützplatten usually have a locking mechanism with sliding and bolt connections. However, these locking mechanisms between the support plate and the support cylinders are relatively heavy, expensive and complicated. In addition, they have parts such. B. on the sliding bolts, which can be lost. The assembly and disassembly of the support plates is complicated because the support head must be hydraulically driven into a receiving socket on the support plate only to be then manually locked in this position. In addition, the angle of rotation between the support cylinder and the support plate is severely limited by the locking pins and the locking mechanism.

Insbesondere bestand bei den bisher für Reachstacker verwendeten Kunststoffabstützplatten mit Steckbolzen das Problem, dass die Abstützplatten weiter als die Räder über den Reachstacker hinausragen. Hierdurch können beim Heranfahren an eine Hindernis die Abstützplatten selbst oder das Hindernis (z. B. ein Container) beschädigt werden. Die Lage der Abstützplatten ist jedoch geometrisch durch die Kippkante und den Platzbedarf bestimmt, so dass die Abstützplatten nicht weiter nach innen verlegt werden können. Auch die Größe der Abstützplatten ist über den maximal zulässigen Bodendruck festgelegt und kann deshalb nicht verkleinert werden. Eine stärkere Verdrehbarkeit der Abstützplatte gegenüber dem Abstützzylinder wäre deshalb von großem Vorteil, da so die Abstützplatte beim Heranfahren an ein Hindernis lediglich verdreht würde und dieses nicht mehr beschädigen könnte.In particular, in the plastic support plates with locking bolts previously used for reachstackers, there was the problem that the support plates protrude further than the wheels beyond the reachstackers. As a result, the support plates themselves or the obstacle (eg a container) can be damaged when approaching an obstacle. However, the position of the support plates is determined geometrically by the tilting edge and the space required, so that the support plates can not be moved further inward. Also, the size of the support plates is set above the maximum allowable ground pressure and therefore can not be reduced. A stronger rotatability of the support plate relative to the support cylinder would therefore of great advantage, since the support plate would only be twisted when approaching an obstacle and this could no longer damage.

Aufgabe der vorliegenden Erfindung ist es daher, eine Abstützplatte zur Verfügung zu stellen, welche einfach aufgebaut und montierbar ist, kostengünstig herzustellen ist, sowie einen großen Verdrehwinkel zum Abstützzylinder aufweist.Object of the present invention is therefore to provide a support plate available, which is simple and installable, is inexpensive to manufacture, and has a large angle of rotation to the support cylinder.

Erfindungsgemäß wird diese Aufgabe von einer Abstützplatte gemäß Anspruch 1 gelöst. Bei der erfindungsgemäßen Abstützplatte erfolgt hierzu die lösbare Verbindung über eine Schnappverbindung. Hierdurch werden keine zusätzlichen Verriegelungselemente wie z. B. Steckbolzen benötigt, welche verloren gehen könnten. Vielmehr kann die Abstützplatte allein durch hydraulisches Verfahren des Abstützzylinders gegen die Abstützplatte mit dieser verbunden werden, ohne dass ein manuelles Verriegeln nötig wäre. Ebenso kann die Demontage der Abstützplatte vom Zylinder durch ein einfaches Verfahren des Abstützzylinders erfolgen, ohne dass eine manuelle Entriegelung nötig wäre. Damit ist über die Schnappverbindung auch eine werkzeuglose Montage und Demontage der erfindungsgemäßen Abstützplatte möglich Zudem ergibt sich durch den Wegfall dieser Verriegelungselemente die Möglichkeit, die Abstützplatte stärker gegen den Abstützzylinder zu verdrehen. Weiterhin erlaubt der Wegfall der bisher verwendeten Verriegelungsmechanismen eine Gewichtsreduzierung sowie eine kostengünstige Produktion.According to the invention, this object is achieved by a support plate according to claim 1. In the support plate according to the invention for this purpose, the releasable connection via a snap connection. As a result, no additional locking elements such. B. socket pin needed, which could be lost. Rather, the support plate can be connected solely by hydraulic method of the support cylinder against the support plate with this, without a manual locking would be necessary. Likewise, the disassembly of the support plate from the cylinder can be done by a simple process of the support cylinder, without manual unlocking would be necessary. This is on the snap connection and a tool-free assembly and disassembly of the support plate according to the invention possible also results from the elimination of these locking elements the ability to rotate the support plate stronger against the support cylinder. Furthermore, eliminating the previously used locking mechanisms allows weight reduction and cost-effective production.

Vorteilhafterweise weist die erfindungsgemäße Abstützplatte dabei eine Aufnahmepfanne zur Aufnahme eines Abstützkopfes des Abstützzylinders auf. Der üblicherweise am Zylinderkolben angebrachte Abstützkopf des Abstützzylinders wird dabei in die Aufnahmepfanne eingeführt und über die Schnappverbindung lösbar mit der Abstützplatte verbunden. Eine manuelle Verriegelung nach Einführen des Abstützkopfes in die Aufnahmepfanne wie im Stand der Technik ist damit nicht mehr nötig, da die Verbindung der beiden Elemente mit Einführen des Abstützkopfes in die Abstützpfanne automatisch über die Schnappverbindung erfolgt. Ebenso erfolgt das Lösen der Verbindung beim Herausziehen des Abstützkopfes aus der Abstützpfanne wiederum ohne manuelles Zutun. Während sich der Abstützzylinder auf die Abstützpfanne stützt, nimmt die Aufnahmepfanne die Kräfte vom Abstützkopf des Abstützzylinders auf und verteilt sie auf die Standfläche der Abstützplatte. Die Aufnahmepfanne ist dabei vorteilhafterweise auf der der Standfläche gegenüber liegenden Seite der Abstützplatte angeordnet.Advantageously, the support plate according to the invention in this case has a receiving socket for receiving a support head of the support cylinder. The usually mounted on the cylinder piston support head of the support cylinder is thereby introduced into the receiving socket and connected via the snap connection releasably connected to the support plate. A manual locking after insertion of the Abstützkopfes in the receiving pan as in the prior art is therefore no longer necessary, since the connection of the two elements with insertion of the Abstützkopfes done in the Abstützpfanne automatically via the snap connection. Likewise, the release of the connection takes place when pulling the Abstützkopfes from the Abstützpfanne turn without manual intervention. While the support cylinder is resting on the support pan, the receiving pan absorbs the forces from the support head of the support cylinder and distributes them to the base of the support plate. The receiving pan is advantageously arranged on the side opposite the support surface of the support plate.

Vorteilhafterweise weist die Aufnahmepfanne einen Hinterschnitt auf, welcher im Zusammenspiel mit dem Abstützkopf die Schnappverbindung bildet. Der Hinterschnitt kann entweder durch die Form der Aufnahmepfanne selbst gebildet werden, oder aber durch ein überkragendes Element. Wird der Abstützkopf in die Aufnahmepfanne eingeführt, verformt oder bewegt sich der Hinterschnitt und gibt so den Zugang für den Abstützkopf frei. Befindet sich der Abstützkopf ganz in der Aufnahmepfanne, bewegt sich der Hinterschnitt in seine ursprüngliche Position zurück und hält die Abstützplatte durch Formschluß am Abstützzylinder. Zum Lösen der Verbindung wird der Abstützkopf wieder aus der Aufnahmepfanne herausgezogen, wobei der Hinterschnitt wiederum entsprechend bewegt oder verformt wird. Ein mechanisches Verriegeln und Entriegeln von Abstützkopf und Abstützplatte kann so vollkommen entfallen.Advantageously, the receiving socket has an undercut, which forms the snap connection in interaction with the support head. The undercut can be formed either by the shape of the receiving pan itself, or by an overhanging element. When the support head is inserted into the receiving socket, the undercut deforms or moves, freeing up access for the support head. The support head is located entirely in the receiving socket, the undercut moves back to its original position and holds the support plate by positive engagement on the support cylinder. To release the connection of the support head is pulled out of the receiving pan again, the undercut is again moved or deformed accordingly. A mechanical locking and unlocking of support head and support plate can be completely eliminated.

Vorteilhafterweise ist dabei der Hinterschnitt elastisch und/oder beweglich ausgeführt. Wird der Hinterschnitt durch die Form der Aufnahmepfanne gebildet, ist der Hinterschnitt vorteilhafterweise aus einem elastischen Material gebildet. Wird der Hinterschnitt von einem separaten Element gebildet, kann dieses Element entweder selbst aus einem elastischen Material bestehen oder aber beweglich ausgeführt sein und mit einem elastischen Element zusammenwirken. Die zum Verformen oder Bewegen des Hinterschnitts nötigen Kräfte können dabei relativ groß sein, da das Einführen des Abstützzylinders in die Aufnahmepfanne über das Verfahren des Zylinderkolbens des Abstützzylinders erfolgt. Ebenso kann das Lösen der Abstützplatte vom Abstützzylinder über ein Verfahren des Kolbens erfolgen. Hierdurch ist eine sichere Verbindung zwischen Abstützzylinder und Abstützplatte gegeben.Advantageously, the undercut is elastic and / or movable. If the undercut is formed by the shape of the receiving pan, the undercut is advantageously formed of an elastic material. If the undercut is formed by a separate element, this element can either even made of an elastic material or be designed to be movable and interact with an elastic element. The forces necessary for deforming or moving the undercut can be relatively large, since the insertion of the support cylinder into the receiving socket takes place via the method of the cylinder piston of the support cylinder. Likewise, the release of the support plate from the support cylinder via a method of the piston can take place. As a result, a secure connection between support cylinder and support plate is given.

Vorteilhafterweise ist dabei der Hinterschnitt einstückig mit der Aufnahmepfanne ausgeführt. Der Hinterschnitt wird dabei vorteilhafterweise von der Form der Aufnahmepfanne bestimmt, welche vorteilhafterweise aus einem elastischen Material gebildet ist. Hierdurch läßt sich ohne jegliche beweglichen Teile eine sichere und einfache Schnappverbindung herstellen, welche zudem kostengünstig produziert werden kann. Allerdings ist es alternativ auch möglich, dass der Hinterschnitt und/oder die gesamte Abstützplatte aus mehreren Teilen zusammengebaut sind.Advantageously, the undercut is made in one piece with the receiving socket. The undercut is advantageously determined by the shape of the receiving pan, which is advantageously formed of an elastic material. As a result, can be made without any moving parts a secure and simple snap connection, which can also be produced inexpensively. However, it is alternatively also possible that the undercut and / or the entire support plate are assembled from several parts.

Vorteilhafterweise ist dabei der Abstützkopf in der Aufnahmepfanne verdrehbar. Da keine zusätzlichen Verriegelungselemente notwendig sind, steht hierfür ausreichend Platz zur Verfügung.Advantageously, the support head is rotatable in the receiving pan. Since no additional locking elements are necessary, this is sufficient space available.

Vorteilhafterweise bilden dabei die Aufnahmepfanne und er Abstützkopf ein Kugelgelenk. Die Aufnahmepfanne weist hierfür eine Aufnahme für einen kugelförmigen Bereich des Abstützkopfes auf, welche vorteilhafterweise im wesentlichen halbkugelförmig geformt ist. Der Hinterschnitt wird nun entweder über elastische oder bewegliche Elemente oberhalb des Randes dieser Halbkugel gebildet, oder aber dadurch, dass die Innenfläche der Aufnahme einem Kugelflächensegment entspricht, welches mehr als nur die Hälfte einer Kugeloberfläche ausmacht. Die an die Halbkugel anschließenden Randbereiche des Kugelflächensegments bilden den Hinterschnitt, der den Kugelkopf des Abstützzylinders an der Abstützplatte hält. Das Kugelgelenk ermöglicht dabei eine besonders große Verdrehbarkeit von Abstützplatte und Abstützzylinder.Advantageously, the receiving socket and the supporting head form a ball joint. The receiving pan has for this purpose a receptacle for a spherical region of the support head, which is advantageously formed substantially hemispherical. The undercut is now formed either over elastic or movable elements above the edge of this hemisphere, or in that the inner surface of the receptacle corresponds to a spherical segment, which accounts for more than half of a spherical surface. The adjoining the hemisphere edge regions of the spherical surface segment form the undercut, which holds the ball head of the support cylinder on the support plate. The ball joint allows a particularly large rotatability of support plate and support cylinder.

Vorteilhafterweise besteht die erfindungsgemäße Abstützplatte aus einem elastischen Material, insbesondere aus Kunststoff. Damit kann die Schnappverbindung z. B. allein über die Flexibilität des Materials, aus welchem die Abstützplatte hergestellt ist, und eine entsprechende Form der Abstützplatte gebildet sein. So läßt sich die erfindungsgemäße Schnappverbindung auf einfache und kostengünstige Art und Weise herstellen, insbesondere wenn Kunststoff zum Einsatz kommt, welcher ohnehin flexibel ist und mit welchem die für die Schnappverbindung notwendige Form der Abstützplatte problemlos erzeugt werden kann.Advantageously, the support plate according to the invention consists of an elastic material, in particular of plastic. Thus, the snap connection z. B. alone on the flexibility of the material from which the support plate is made, and a corresponding shape of the support plate may be formed. Thus, the snap connection according to the invention can be produced in a simple and cost-effective manner, in particular if plastic is used, which is flexible anyway and with which the necessary form of the support plate for the snap connection can be easily generated.

Vorteilhafterweise ist die erfindungsgemäße Abstützplatte dabei einstückig ausgeführt. Dies ermöglicht eine ebenso einfache wie stabile Konstruktion, welche kostensparend hergestellt werden kann. Alternativ ist es aber auch denkbar, eine aus mehreren Teilen zusammengesetzte Abstützplatte zu verwenden.Advantageously, the support plate according to the invention is carried out in one piece. This allows a simple and stable construction, which can be produced cost-saving. Alternatively, it is also conceivable to use a composite of several parts support plate.

Die vorliegende Erfindung umfaßt weiterhin eine Abstreifvorrichtung zum Ablösen einer der oben beschriebenen Abstützplatten vom Abstützzylinder, welche beim Einfahren des Zylinderkolbens des Abstützzylinders die Abstützplatte vom Abstützzylinder abstreift. So läßt sich die erfindungsgemäße Abstützplatte nicht nur einfach durch Ausfahren des Zylinderkolbens montieren, sondern durch Einfahren des Zylinderkolbens auch einfach wieder demontieren.The present invention further comprises a stripping device for detaching one of the support plates described above from the support cylinder, which strikes off the support plate from the support cylinder when retracting the cylinder piston of the support cylinder. Thus, the support plate according to the invention can be mounted not only by simply extending the cylinder piston, but also simply dismantle by retracting the cylinder piston.

Vorteilhafterweise wird die Abstreifvorrichtung dabei zwischen Abstützzylinder und Abstützplatte angeordnet, so dass die Abstützplatte beim Einfahren des Zylinderkolbens des Abstützzylinders gegen die Abstreifvorrichtung fährt. Durch weiteres Einfahren des Zylinderkolbens wird so der Abstützkopf aus der Aufnahmepfanne herausgezogen.Advantageously, the stripping device is arranged between the support cylinder and support plate, so that the support plate moves against the stripping device during retraction of the cylinder piston of the support cylinder. By further retraction of the cylinder piston so the support head is pulled out of the receiving socket.

Die erfindungsgemäße Abstreifvorrichtung kann dabei fest mit dem Abstützzylinder und/oder dem Gerät verbunden sein. So kann die Abstützplatte ohne weitere Elemente schnell und einfach montiert und demontiert werden. Die Abstreifvorrichtung kann dabei entweder am Zylinder selbst oder auch an benachbarten Bauteilen des Fahrzeugs befestigt sein.The stripping device according to the invention can be firmly connected to the support cylinder and / or the device. So the support plate can be quickly and easily assembled and disassembled without any further elements. The stripping device can be attached either to the cylinder itself or to adjacent components of the vehicle.

Alternativ kann die Abstreifvorrichtung jedoch auch ein separates Element bilden. Insbesondere hat dies den Vorteil, dass auch bestehende Abstützzylinder mit der erfindungsgemäßen Abstützplatte und Abstreifvorrichtung nachgerüstet werden können. Dabei weist die Abstreifvorrichtung vorteilhafterweise eine längliche Aufnahme auf, mit welcher sie seitlich auf den Zylinderkolben des Abstützzylinders aufgeschoben werden kann. Wird der Zylinderkolben nun eingefahren, fährt die Abstützplatte gegen die Abstreifvorrichtung und wird so vom Abstützkopf des Abstützzylinders gelöst.Alternatively, however, the stripping device can also form a separate element. In particular, this has the advantage that existing support cylinders can be retrofitted with the support plate and stripping device according to the invention. In this case, the stripping device advantageously has an elongated receptacle, with which it can be pushed laterally onto the cylinder piston of the support cylinder. If the cylinder piston is now retracted, the support plate moves against the scraper and is thus released from the support head of the support cylinder.

Figur 1 zeigt einen Abstützzylinder 2 mit der erfindungsgemäßen Abstützplatte 1. Der Abstützzylinder 2 ist dabei über Bolzen 15 mit einem Trägerelement 20 eines verfahrbaren Gerätes, hier eines Reachstackers, verbunden. Der Abstützzylinder ist dabei vertikal ausgerichtet und umfaßt den mit dem verfahrbaren Gerät verbundenen Zylinder 3 sowie den hydraulisch verstellbaren Zylinderkolben 4. Am unteren Ende des Zylinderkolbens 4 befindet sich der Abstützkopf 5 des Abstützzylinders, welcher über eine Schnappverbindung mit der Abstützplatte 1 verbindbar ist. Zum Abstützen den Gerätes in einer Arbeitsposition wird dabei der Zylinderkolben 4 des Abstützzylinders 2 ausgefahren, bis das verfahrbare Gerät auf dem Abstützzylinder ruht. Die Abstützplatte verteilt dabei das auf dem Abstützzylinder ruhende Gewicht des verfahrbaren Gerätes auf ihrer Standfläche. Das verfahrbare Gerät umfasst dabei üblicherweise 4 Abstützzylinder, auf welchen es in der Arbeitsposition ruht. FIG. 1 shows a support cylinder 2 with the support plate according to the invention 1. The support cylinder 2 is connected via bolts 15 with a support member 20 of a movable device, here a Reachstackers connected. The support cylinder is vertically aligned and comprises the cylinder connected to the movable device 3 and the hydraulically adjustable cylinder piston 4. At the lower end of the cylinder piston 4 is the support head 5 of the support cylinder, which is connectable via a snap connection with the support plate 1. To support the device in a working position while the cylinder piston 4 of the support cylinder 2 is extended until the movable device rests on the support cylinder. The support plate distributes the resting on the support cylinder weight of the movable device on its base. The movable device usually comprises 4 support cylinders on which it rests in the working position.

Der Aufbau der Abstützplatte 1 ist dabei insbesondere aus den Schnittansichten in Figur 2 und Figur 3 zu sehen. Die Abstützplatte 1 umfasst auf ihrer Unterseite eine Standfläche 11, mit welcher sie auf den Boden aufgesetzt wird. Auf ihrer Oberseite weist die erfindungsgemäße Abstützplatte 1 schräge Seitenflächen 13 auf, welche vom äußeren Rand der Abstützplatte schräg nach innen und oben verlaufen. Die Aufnahmepfanne 6 der erfindungsgemäßen Abstützplatte befindet sich in der Mitte der Oberseite und ist nach oben hin offen. Die Aufnahmepfanne 6 weist dabei eine im wesentlichen halbkugelförmige Innenfläche auf, welche zusammen mit dem Kugelkopf 5 des Abstützzylinders ein Kugelgelenk bildet. Die Innenfläche der Aufnahmepfanne 6 geht dabei etwas über eine Halbkugel hinaus, so dass sie einem Kugelflächensegment entspricht, welches mehr als nur die Hälfte einer Kugeloberfläche ausmacht. Die über eine Halbkugel hinausgehenden Randbereiche des Kugelflächensegments bilden den Hinterschnitt 7, welcher den Kugelkopf 5 an der Abstützplatte hält. Diese einstückige Ausführung von Aufnahmepfanne 6 und Hinterschnitt 7 ergibt eine einfache und kostengünstige Konstruktion, welche dennoch eine optimale Verdrehbarkeit der Abstützplatte gegen den Abstützzylinder ermöglicht.The structure of the support plate 1 is in particular from the sectional views in FIG. 2 and FIG. 3 to see. The support plate 1 comprises on its underside a Stand 11, with which it is placed on the ground. On its upper side, the support plate 1 according to the invention has oblique side surfaces 13 which extend obliquely inwards and upwards from the outer edge of the support plate. The receiving pan 6 of the support plate according to the invention is located in the middle of the top and is open at the top. The receiving pan 6 in this case has a substantially hemispherical inner surface, which forms a ball joint together with the ball head 5 of the supporting cylinder. The inner surface of the receiving pan 6 goes slightly beyond a hemisphere, so that it corresponds to a spherical segment, which makes up more than half of a spherical surface. The over a hemisphere outgoing edge regions of the spherical surface segment form the undercut 7, which holds the ball head 5 on the support plate. This one-piece design of receiving socket 6 and undercut 7 results in a simple and inexpensive construction, which nevertheless allows optimal rotatability of the support plate against the support cylinder.

Die Seitenwände der Aufnahmepfanne 6, welche den Hinterschnitt 7 tragen, werden dabei von einem im wesentlichen ringförmigen Element 12 gebildet, welches aus der Oberfläche der Abstützplatte herausragt. Diese Anordnung hat den Vorteil, dass zum bewegen des Hinterschnitts 7 nur das ringförmige Element 12 verformt werden muss, so dass über dessen Wandstärke die zum Öffnen oder Schließen der Schnappverbindung notwendige Kraft unabhängig von der Größe des Hinterschnitts eingestellt werden kann.The side walls of the receiving pan 6, which carry the undercut 7, are thereby formed by a substantially annular element 12, which protrudes from the surface of the support plate. This arrangement has the advantage that only the annular element 12 has to be deformed for moving the undercut 7, so that the force required to open or close the snap connection can be adjusted independently of the size of the undercut via its wall thickness.

Die erfindungsgemäße Abstützplatte besteht aus Kunststoff, so dass insbesondere das ringförmige Element 12, an welchem sich der Hinterschnitt 7 befindet, elastisch ist. Zur Montage der Abstützplatte wird die Aufnahmepfanne 6 unter dem Abstützkopf 5 des Abstützzylinders 2 positioniert und der Zylinderkolben 4 abgesenkt. Der Abstützkopf 5 dehnt dabei den ringförmigen Bereich 12 soweit, bis der Kugelkopf 5 an dem Hinterschnitt 7 vorbei gleiten kann. Ist der Abstützkopf 5 ganz in die Aufnahmepfanne 6 hineingeschoben, verformt sich das elastische Material zurück, so dass der Hinterschnitt 7 den Abstützkopf nun an der Abstützplatte hält. Der Abstützkopf und die Aufnahmepfanne weisen dabei im wesentlichen den gleichen Radius auf, wobei der Radius der Aufnahmepfanne leicht größer sein kann als der des Abstützkopfes. So kann die Abstützplatte einfach gegen den Abstützzylinder verdreht werden.The support plate according to the invention is made of plastic, so that in particular the annular element 12, on which the undercut 7 is, is elastic. For mounting the support plate, the receiving socket 6 is positioned under the support head 5 of the support cylinder 2 and the cylinder piston 4 is lowered. The support head 5 thereby expands the annular region 12 until the ball head 5 can slide past the undercut 7. If the support head 5 is pushed completely into the receiving socket 6, the elastic material deforms back, so that the undercut 7 now holds the support head against the support plate. The support head and the receiving pan have substantially the same radius, wherein the radius of the receiving pan can be slightly larger than that of the support head. Thus, the support plate can be easily rotated against the support cylinder.

Figur 3 zeigt nochmals in einer vergrößerten Schnittdarstellung die erfindungsgemäße Schnappverbindung. Der Hinterschnitt 7 an der Aufnahmepfanne 6 der Abstützplatte hält dabei einen kugelförmigen Bereich des Abstützkopfes in der Aufnahmepfanne, so dass Abstützkopf und Aufnahmepfanne ein Kugelgelenk bilden. Die Aufnahmepfanne ist dabei nach oben offen und weist in ihrem oberen Randbereich einen zylinderförmigen Bereich 13 auf, welcher den Hinterschnitt 7 verstärkt. An den zylinderförmigen Bereich 13 schließt der kugelflächenförmige Aufnahmebereich 6 an, welcher größer ist als eine Halbkugel und so durch seine Form selbst den Hinterschnitt 7 bildet. Die Verdrehbarkeit der Abstützplatte am Abstützzylinder wird dabei lediglich durch die Dicke des Halses 11 des Abstützkopfes 5, die Höhe des zylinderförmigen Bereichs 13 sowie die Dicke der Wandung 12 der Aufnahmepfanne bestimmt. FIG. 3 shows again in an enlarged sectional view of the snap connection according to the invention. The undercut 7 on the receiving socket 6 of the support plate thereby holds a spherical portion of the support head in the receiving socket, so that support head and receiving socket form a ball joint. The receiving pan is open at the top and has in its upper edge region on a cylindrical portion 13 which reinforces the undercut 7. To the cylindrical portion 13 of the spherical surface-shaped receiving portion 6 connects, which is larger than a hemisphere and thus forms the undercut 7 by its shape. The rotatability of the support plate on the support cylinder is determined only by the thickness of the neck 11 of the support head 5, the height of the cylindrical portion 13 and the thickness of the wall 12 of the receiving pan.

Zur Montage der erfindungsgemäßen Anstützplatte muss diese lediglich unter dem Abstützzylinder platziert werden und der Abstützkopf 5 in die Aufnahmepfanne 6 der Abstützplatte geschoben werden, indem der Abstützzylinder ausgefahren wird. Die Schnappverbindung hält dann die Abstützplatte automatisch am Abstützzylinder, ohne dass eine manuelle Verriegelung notwendig wäre.For mounting the support plate according to the invention this must be placed only under the support cylinder and the support head 5 are pushed into the receiving socket 6 of the support plate by the support cylinder is extended. The snap connection then holds the support plate automatically on the support cylinder, without a manual locking would be necessary.

Die Demontage der erfindungsgemäßen Abstützplatte ist in Figur 4 zu sehen. Dabei kommt eine Abstreifvorrichtung 10 zum Einsatz, welche hier die Form eines Halbzylinders aufweist. Die Abstreifvorrichtung wird so seitlich auf den Zylinderkolben 4 aufgeschoben und befindet sich zwischen der Oberkante 8 der Abstützplatte und der Unterkante des Zylinders 3. Wird nun der Zylinderkolben 4 in den Zylinder 3 eingezogen, fährt die Abstützplatte 1 mit ihrer oberen Kante 8 gegen die Abstreifvorrichtung. Der Zylinderkopf kann nun durch weiteres Einfahren des Zylinderkolbens 4 aus der Aufnahmepfanne herausgezogen werden. Damit kann auch die Demontage der Abstützplatte ohne manuelles Zutun einfach über ein Verfahren des Abstützzylinders erfolgen.The disassembly of the support plate according to the invention is in FIG. 4 to see. In this case, a stripping device 10 is used, which here has the shape of a half-cylinder. The stripping device is pushed laterally on the cylinder piston 4 and is located between the upper edge 8 of the support plate and the lower edge of the cylinder 3. If now the cylinder piston 4 retracted into the cylinder 3, the support plate 1 moves with its upper edge 8 against the stripping. The cylinder head can now be pulled out of the receiving socket by further retraction of the cylinder piston 4. So can the Dismantling of the support plate without manual intervention simply done by a method of the support cylinder.

Alternativ zu der hier gezeigten separaten Abstreifvorrichtung kann die Abstreifvorrichtung auch fest mit dem Abstützzylinder 2 verbunden werden. Die Abstreifvorrichtung kann dann auch einen durchgehenden unteren Rand aufweisen, gegen welchen die Oberkante 8 der Abstützplatte beim Einfahren des Zylinder 4 fährt. Ebenso können aber auch eine oder mehrere Vorsprünge am unteren Rand des Zylinders 3 angeordnet werden und als Abstreifvorrichtung dienen.As an alternative to the separate stripping device shown here, the stripping device can also be firmly connected to the support cylinder 2. The stripping device can then also have a continuous lower edge against which the upper edge 8 of the support plate moves when retracting the cylinder 4. Likewise, however, one or more projections on the lower edge of the cylinder 3 can be arranged and serve as a stripping device.

Durch die erfindungsgemäße Kugelgelenk-Schnappverbindung zwischen Abstützplatte und Abstützzylinder steht eine Abstützplatte, insbesondere eine Kunststoffabstützplatte, zur Verfügung, welche einen großen Verdrehwinkel mit dem Abstützzylinder aufweist. Zudem läßt sich die Abstützplatte werkzeuglos montieren und demontieren, wobei auch keine weiteren Bauteile, welche verloren gehen könnten, erforderlich sind. Die Abstützplatte ist dabei einstückig ohne jegliche bewegliche Teile und vorteilhafterweise aus Kunststoff ausgeführt, so dass Gewicht und Preis erheblich reduziert werden konnten.The inventive ball joint snap connection between the support plate and the support cylinder is a support plate, in particular a Kunststoffabstützplatte available, which has a large angle of rotation with the support cylinder. In addition, the support plate can be assembled and disassembled without tools, with no other components that could be lost, are required. The support plate is made in one piece without any moving parts and advantageously made of plastic, so that weight and price could be significantly reduced.

Montage und Demontage erfolgen dabei durch Ein- und Ausfahren des Hydraulikzylinders, wobei zur Demontage die erfindungsgemäße Abstreifvorrichtung zum Einsatz kommt. Die erfindungsgemäße Abstützplatte kann dabei bei all den Geräten zum Einsatz kommen, bei welchen bisher Abstützplatten mit herkömmlichen Verriegelungsmechanismen verwendet wurden.Assembly and disassembly are carried out by retraction and extension of the hydraulic cylinder, wherein for disassembly the scraper device according to the invention is used. The support plate according to the invention can be used in all the devices in which previously support plates were used with conventional locking mechanisms.
