Description
Die vorliegende Erfindung betrifft eine Brechbacke für einen Backenbrecher, die austauschbar an einer bewegbaren Brecherschwinge oder an einem ruhenden Rahmenteil des Backenbrechers anordbar ist, und wobei die Brechbacke eine aktive Brechbackenoberfläche aufweist, mit der in den Backenbrecher eingebbares Brechgut gebrochen werden kann.The present invention relates to a crushing jaw for a jaw crusher, which can be arranged exchangeably on a movable crusher rocker or on a stationary frame part of the jaw crusher, and wherein the crushing jaw has an active crushing jaw surface, can be broken with the crushable material which can be introduced into the jaw crusher.
Die
Bei großen Backenbrechern können die Brechbacken eine Masse von mehreren Tonnen aufweisen. Folglich besteht nicht mehr die Möglichkeit, die Brechbacke mit Muskelkraft, also mit einer oder mit wenigen Personen, von der Brecherschwinge oder dem ruhenden Rahmenteil des Backenbrechers zu lösen, beispielsweise um eine verschlissene Brechbacke gegen eine neue Brechbacke auszutauschen.For large jaw crushers, the crushing jaws may have a mass of several tons. Consequently, it is no longer possible to solve the crushing jaw with muscle power, so with one or a few people, from the crusher swing or the stationary frame part of the jaw crusher, for example, to exchange a worn crushing jaw for a new crushing jaw.
Ein weiterer Nachteil konventioneller Brechbacken besteht darin, dass beim Austausch einer verschlissenen Brechbacke eine große Masse an Stahl ausgetauscht werden muss, wobei jedoch im Wesentlichen nur die aktive Brechbackenoberfläche verschlissen ist. Ein weiterer Nachteil besteht darin, dass die einteilige Brechbacke aus einem einzigen Material ausgebildet werden muss, beispielsweise aus einem Manganstahl.Another disadvantage of conventional crushing jaws is that when replacing a worn crushing jaw a large mass of steel must be replaced, but essentially only the active The crushing jaw surface is worn. Another disadvantage is that the one-piece crushing jaw must be formed of a single material, for example of a manganese steel.
Die
Aufgabe der Erfindung ist die Weiterbildung einer Brechbacke, mit der die vorstehend aufgezeigten Nachteile überwunden werden können. Insbesondere soll die Möglichkeit geschaffen werden, eine verschlissene Brechbacke beispielsweise im Rahmen einer Wartung zu erneuern, ohne große Massen bewegen zu müssen. Die vorteilhafte Prismenstruktur der Brechbackenoberfläche soll dabei möglichst erhalten bleiben. Insbesondere soll die Möglichkeit erhalten bleiben, dass die Brechbacke auf konventionelle Weise an der Brecherschwinge oder am Rahmenteil des Backenbrechers angeordnet werden kann.The object of the invention is the development of a crushing jaw, with which the above-mentioned disadvantages can be overcome. In particular, the possibility should be created to renew a worn crushing jaw, for example, as part of a maintenance, without having to move large masses. The advantageous prism structure of the crushing jaw surface should remain as possible. In particular, the possibility should be retained that the crushing jaw can be arranged in a conventional manner on the crusher rocker arm or on the frame part of the jaw crusher.
Diese Aufgabe wird ausgehend von einer Brechbacke für einen Backenbrecher gemäß dem Oberbegriff des Anspruchs 1 in Verbindung mit den kennzeichnenden Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved on the basis of a crushing jaw for a jaw crusher according to the preamble of
Die Erfindung schließt die technische Lehre ein, dass die Brechbacke eine Grundplatte zur Anordnung an der Brecherschwinge oder am ruhenden Rahmenteil aufweist, wobei an der Grundplatte Brechelemente lösbar angeordnet sind und durch die die Brechbackenoberfläche wenigstens teilweise gebildet wird.The invention includes the technical teaching that the crushing jaw has a base plate for placement on the crusher rocker arm or on the stationary frame part, wherein crushing elements are detachably arranged on the base plate and through which the crushing jaw surface is at least partially formed.
Erfindungsgemäß wird eine Brechbacke geschaffen, die mehrteilig aufgebaut ist und eine Grundplatte aufweist, die auch bei einem Service, insbesondere bei einer Erneuerung einer verschlissenen Brechbackenoberfläche, an der Brecherschwinge oder am ruhenden Rahmenteil verbleiben kann. Durch den einfachen Austausch kleinerer Brechelemente, die aufgrund ihrer geringeren Masse gegebenenfalls auch mit Muskelkraft, d.h. händisch bewegt werden können, kann die Brechbackenoberfläche erneuert werden. Durch die Ausgestaltung der Brechbackenelemente kann dabei insbesondere eine Prismenstruktur oder eine Wellenstruktur gebildet werden. Die Brechelemente sind stabförmig ausgebildet und parallel zueinander an der Grundplatte zur Bildung der Brechbackenoberfläche angeordnet. Insbesondere können die Brechelemente eine Prismenstruktur oder eine Wellenstruktur bilden. Unter einem stabförmigen Brechelement wird jeder Körper verstanden, der eine Hauptachse aufweist, in der sich der Körper erstreckt, wobei der Querschnitt, mit dem sich der Körper entlang der Hauptachse erstreckt, frei gewählt werden kann und der Querschnitt kann sich beispielsweise auch entlang der Hauptachse verändern. So kann das Brechelement entlang der Hauptachse gleichförmig ausgebildet sein oder dieser kann sich beispielsweise verjüngen.According to the invention, there is provided a crushing jaw which is constructed in several parts and has a base plate which can remain on the breaker rocker or on the stationary frame part even during a service, in particular during a renewal of a worn breaking jaw surface. Due to the simple exchange of smaller refractive elements, which, due to their lower mass, may also be replaced by muscle power, i. can be moved manually, the crushing jaw surface can be renewed. In particular, a prism structure or a wave structure can be formed by the configuration of the crushing-jaw elements. The crushing elements are rod-shaped and arranged parallel to each other on the base plate to form the crushing jaw surface. In particular, the breaking elements may form a prism structure or a wave structure. A rod-shaped breaking element is understood to be any body having a major axis in which the body extends, wherein the cross section with which the body extends along the main axis can be chosen freely, and the cross section can also change along the major axis, for example , Thus, the refractive element along the main axis may be uniform or this may, for example, taper.
Die Stabform beschreibt dabei einen Schlankheitsgrad der Brechelemente, die beispielsweise mit einem Schlankheitswert von 1:3, bevorzugt von 1:5 und besonders bevorzugt von 1:10 ausgebildet sind, wodurch das Verhältnis von Durchmesser oder Querschnittshauptmaß zur Länge angegeben ist.The rod shape describes a degree of slimming of the crushing elements, which are formed, for example, with a slenderness value of 1: 3, preferably 1: 5 and particularly preferably 1:10, whereby the ratio of diameter or cross section main dimension is given to the length.
Ein weiterer Vorteil der erfindungsgemäßen Brechbacke entsteht dadurch, dass für die Bildung der Grundplatte ein anderer Werkstoff Verwendung finden kann als für die Bildung der stabförmigen Brechelemente. Beispielsweise kann die Grundplatte aus einem Manganstahl bestehen, während die stabförmigen Brechelemente aus einem XAR400 oder aus einem XAR600 bestehen kann (Werkstoff Nr. 1.8735). Die Brechelemente können auch aus einem Keramikmaterial ausgebildet sein oder dieses umfassen, wobei auch weitere insbesondere harte und verschleißfeste Materialien Verwendung finden können.Another advantage of the crushing jaw according to the invention arises from the fact that a different material can be used for the formation of the base plate than for the formation of the rod-shaped crushing elements. For example, the base plate may consist of a manganese steel while the rod-shaped crushing elements consist of XAR400 or XAR600 (material no. 1.8735). The crushing elements may also be formed from or comprise a ceramic material, although other particularly hard and wear-resistant materials may be used.
Die stabförmigen Brechelemente bilden erfindungsgemäß verschleißlastige Austauschteile der Brechbacke, und ist die Brechbacke verschlissen, können nur die stabförmigen Brechelemente ausgetauscht werden, um die Brechbacke mit der gleichen Grundplatte wieder in einen im Wesentlichen neuen Zustand zu versetzen. Dabei können die stabförmigen Elemente einen Querschnitt aufweisen, der quadratisch oder beispielsweise rautenförmig ausgebildet ist, sodass bei einem entsprechenden Einsetzen der stabförmigen Brechelemente die Prismenstruktur gebildet werden kann. Auch ist es denkbar, dass die stabförmigen Brechelemente rund ausgebildet sind und so an der Grundplatte befestigt werden, dass eine (Halb-) Wellenstruktur entsteht.According to the invention, the rod-shaped breaking elements form wear-resistant replacement parts of the crushing jaw, and if the crushing jaw is worn, only the rod-shaped crushing elements can be exchanged in order to put the crushing jaw with the same base plate back into a substantially new state. In this case, the rod-shaped elements may have a cross section which is square or, for example, diamond-shaped, so that when a corresponding insertion of the rod-shaped crushing elements, the prism structure can be formed. It is also conceivable that the rod-shaped crushing elements are round and are attached to the base plate so that a (half) wave structure is formed.
Mit besonderem Vorteil können die stabförmigen Brechelemente, die einen quadratischen oder rautenförmigen Querschnitt aufweisen, mit einer oben liegenden Längskante an der Grundplatte angeordnet werden. Hierzu kann die Grundplatte Aufnahmetaschen aufweisen, in denen die stabförmigen Brechelemente einliegen. Sind die stabförmigen Brechelemente beispielsweise mit einem quadratischen Querschnitt ausgebildet, können die Aufnahmetaschen eine dreieckförmige längs ausgebildete Vertiefung bilden, und die quadratischen Brechelemente können mit einer Kante nach unten in die Aufnahmetaschen eingesetzt werden und damit liegen formschlüssig in diesen ein. Folglich entsteht eine oben liegende Längskante, wobei mehrere stabförmige Brechelemente parallel zueinander an der Grundplatte befestigt werden, sodass auch parallel zueinander mehrere obenliegende Längskanten gebildet werden, wodurch im Ergebnis eine Brechbacke bereitgestellt wird, die eine Prismenstruktur aufweist.With particular advantage, the rod-shaped crushing elements, which have a square or diamond-shaped cross-section, can be arranged with an upper longitudinal edge on the base plate. For this purpose, the base plate can have receiving pockets in which the rod-shaped breaking elements are inserted. If the rod-shaped crushing elements are formed, for example, with a square cross-section, the receiving pockets can form a triangular longitudinal recess, and the square crushing elements can be inserted with an edge down into the receiving pockets and thus lie positively in this one. Consequently, an upper longitudinal edge is formed, wherein a plurality of rod-shaped breaking elements are fastened parallel to one another on the base plate, so that a plurality of upper longitudinal edges are formed parallel to one another, as a result of which a crushing jaw having a prismatic structure is provided.
Zur Anordnung der stabförmigen Brechelemente sind erfindungsgemäß Klemmelemente vorgesehen, die mittels Schraubelementen unter Bildung eines Formschlusses mit den stabförmigen Brechelementen an der Grundplatte befestigt sind. Dabei können die Klemmelemente beispielsweise Durchgangslöcher aufweisen, durch die die Schraubelemente hindurchgeführt werden, und zwischen den Aufnahmetaschen in der Grundplatte können Gewindebohrungen eingebracht sein, in die die Schraubelemente mit den Klemmelementen eingeschraubt werden können, wenn die stabförmigen Brechelemente zuvor in die Aufnahmetaschen eingesetzt wurden. So können die Brechelemente an der Grundplatte verklemmt werden, während diese in ihren zugeordneten Aufnahmetaschen einliegen.For arranging the rod-shaped crushing elements according to the invention clamping elements are provided, which are fastened by means of screw elements to form a positive connection with the rod-shaped crushing elements on the base plate. In this case, the clamping elements, for example, through holes have, through which the screw elements are passed, and between the receiving pockets in the base plate threaded holes can be introduced, in which the screw elements can be screwed with the clamping elements, when the rod-shaped breaking elements have been previously inserted into the receiving pockets. Thus, the crushing elements can be clamped to the base plate while they are in their associated receiving pockets.
Mit weiterem Vorteil können sich die stabförmigen Brechelemente im Wesentlichen über der gesamten Höhe der Grundplatte erstrecken. Erfindungsgemäß sind die Klemmelemente zwischen den parallel zueinander an der Grundplatte angeordneten stabförmigen Brechelementen angeordnet und klemmen diese über ihre Längskanten. Zusätzlich können auch an den Endseiten der stabförmigen Brechelemente weitere Klemmelemente vorgesehen sein, die die stabförmigen Brechelemente in der Grundplatte verkeilen. Unter einem Klemmen wird vorliegend eine Befestigungsart mit einem Formschluss verstanden, insbesondere wie dieser auch durch die Verwendung einer Klammer entsteht. Die Kraftschlussrichtung, die vorliegend einer Kopfrichtung entspricht und damit orthogonal über der Ebene der Grundplatte steht, teilt sich beim vorliegenden Klemmen auf Schrägen an den Brechelementen auf, durch die eine auf die Brechelemente ausübbare Haltekraft verstärkt werden kann.With further advantage, the rod-shaped crushing elements may extend substantially over the entire height of the base plate. According to the invention, the clamping elements are arranged between the rod-shaped breaking elements arranged parallel to one another on the base plate and clamp them over their longitudinal edges. In addition, further clamping elements can be provided on the end sides of the rod-shaped crushing elements, which wedge the rod-shaped crushing elements in the base plate. Clamping in the present case is understood to mean a type of fastening with a form-fit connection, in particular as this is also produced by the use of a clamp. The frictional connection direction, which in the present case corresponds to a head direction and thus is orthogonal to the plane of the base plate, is divided in the present clamping on bevels on the refractive elements, can be amplified by a exercisable on the refractive elements holding force.
Gemäß einer abgewandelten Ausführungsform können die stabförmigen Brechelemente auch eine Länge aufweisen, die nur einem Teil der gesamten Höhe der Grundplatte entspricht, wobei zwei oder mehr stabförmige Brechelemente sich in einer gemeinsamen Längsrichtung erstreckend an der Grundplatte angeordnet sind. Die Höhenrichtung der Grundplatte entspricht dabei der Erstreckungsrichtung vom Zuführbereich des Brechgutes bis in den unteren Brechspalt hinein, und stabförmige Brechelemente im unteren Bereich der Brechbacke, die einem stärkeren Verschleiß ausgesetzt sind, können beispielsweise häufiger ausgetauscht werden als stabförmige Brechelemente im oberen Mündungsbereich des Brechraumes.According to a modified embodiment, the rod-shaped breaking elements may also have a length which corresponds to only a part of the total height of the base plate, wherein two or more rod-shaped breaking elements are arranged in a common longitudinal direction extending to the base plate. The height direction of the base plate corresponds to the extension direction of the feed region of the crushed material into the lower crushing gap, and rod-shaped crushing elements in the lower region of the crushing jaw, which are exposed to greater wear, for example, can be replaced more often than rod-shaped crushing elements in the upper mouth region of the crushing space.
Zur Befestigung der verkürzten stabförmigen Brechelemente können Keilelemente vorgesehen sein, die mittels Schraubelementen an der Grundplatte angeordnet werden und die die in einer gemeinsamen Längsrichtung angeordneten stabförmigen Brechelemente über ihre Endseiten an der Grundplatte halten. Beispielsweise kann die Grundplatte am oberen und unteren Ende eine Hinterschneidung nach Art einer Schwalbenschwanzkontur aufweisen, und die Keilelemente können sich zwischen den in einer gemeinsamen Längsrichtung angeordneten Brechelementen befinden. Auch die Keilelemente können Durchgangsbohrungen aufweisen, durch die die Schraubelemente hindurchgeführt werden und in der Grundplatte können Gewindebohrungen vorgesehen sein, in die die Schraubelemente eingeschraubt werden. So kann das Keilelement beispielsweise Keilschrägen aufweisen, die mit angeschrägten Endseiten der Brechelemente korrespondieren, und mit einem Keilelement können beispielsweise zwei benachbarte Brechelemente an der Grundplatte verkeilt werden.For fastening the shortened rod-shaped crushing elements wedge elements can be provided, which are arranged by means of screw elements on the base plate and hold the arranged in a common longitudinal direction rod-shaped crushing elements on their end sides to the base plate. For example, the base plate may have an undercut in the manner of a dovetail contour at the upper and lower ends, and the wedge elements may be located between the crushing elements arranged in a common longitudinal direction. Also, the wedge elements may have through holes through which the screw elements are passed and in the base plate threaded holes may be provided, into which the screw elements are screwed. Thus, the wedge element, for example, have wedge slopes which correspond to bevelled end sides of the crushing elements, and with a wedge element, for example, two adjacent crushing elements can be wedged to the base plate.
Die in Zusammenhang mit dem ersten Ausführungsbeispiel verwendeten Klemmelemente, die zwischen den sich längs erstreckenden stabförmigen Brechelementen angeordnet werden können um diese an der Grundplatte zu befestigen, können auch für verkürzt ausgeführte Brechelemente verwendet werden, die in Zusammenhang mit dem zweiten Ausführungsbeispiel beschrieben sind.The clamping elements used in connection with the first embodiment, which can be arranged between the longitudinally extending rod-shaped breaking elements to attach them to the base plate, can also be used for shortened breaking elements, which are described in connection with the second embodiment.
