Description
Die Erfindung betrifft eine Abbaumaschine zum Abarbeiten einer Bodenoberfläche nach dem Oberbegriff des Anspruchs 1, sowie ein Verfahren zum Spannen eines Transportbandes einer Transporteinrichtung bei einer Abbaumaschine nach dem Oberbegriff des Anspruchs 11.The invention relates to a mining machine for processing a ground surface according to the preamble of
Derartige Abbaumaschinen werden im Tagebau, Erd- und Felsbau eingesetzt, wobei eine solche Abbaumaschine z. B. Gestein in einem Arbeitsgang schneidet, bricht und lädt, ohne dass Sprengvorgänge notwendig sind.Such mining machines are used in opencast mining, earthworks and rock, with such a mining machine z. B. rocks in one operation cuts, breaks and loads, without blasting operations are necessary.
Derartige Abbaumaschinen sind z. B. aus der
Als Abbauwerkzeug wird eine Schneidwalze verwendet, die das Abbaumaterial auf eine Transporteinrichtung übertragen kann, die innerhalb des Maschinenrahmens ortsfest aber auswechselbar angeordnet sein kann. Das Abbaumaterial wird schräg nach oben auf der Transporteinrichtung bis zu einer Abwurfstelle transportiert, an der das Abbaumaterial z. B. auf einen LKW abgeworfen werden kann. Im Falle von zwei Transporteinrichtungen erfolgt der Abwurf auf eine zweite Transporteinrichtung, deren unteres Ende sich unterhalb des oberen Endes der ersten Transporteinrichtung befindet. Die zweite Transporteinrichtung transportiert das Abbaumaterial von einer Übernahmestelle am unteren Ende der zweiten Transporteinrichtung ebenfalls nach oben zu einer Abwurfstelle, an der das Abbaumaterial entweder auf ein Transportfahrzeug oder auch seitlich neben der Abbaumaschine abgeworfen werden kann. Hierzu kann die zweite Transporteinrichtung seitlich um jeweils ±90° verschwenkbar sein, indem eine Bandaufhängeeinrichtung für die zweite Transporteinrichtung um eine vertikale Achse schwenkbar ist, die virtuell beispielsweise durch die Übernahmestelle hindurchläuft.As a mining tool, a cutting roller is used, which can transfer the decomposition material to a transport device, which may be arranged stationary but replaceable within the machine frame. The excavation material is transported obliquely upwards on the transport device to a discharge point at which the decomposition material z. B. can be dropped on a truck. In the case of two transport devices, the discharge takes place on a second transport device whose lower end is located below the upper end of the first transport device. The second transport device transports the decomposition material from a transfer point at the lower end of the second transport device also up to a discharge point at which the excavation material can be dropped either on a transport vehicle or laterally next to the mining machine. For this purpose, the second transport device can be pivoted laterally by ± 90 ° in each case in that a belt suspension device for the second transport device can be pivoted about a vertical axis, which runs virtually through the transfer point, for example.
Zusätzlich ist die zweite Transporteinrichtung um eine horizontale Schwenkachse schwenkbar, um das obere Ende der zweiten Transporteinrichtung auf eine gewünschte Abwurfhöhe zu bringen. Die Angaben vertikal und horizontal sind so zu verstehen, dass die Abbaumaschine auf einem horizontalen Boden steht.In addition, the second transport means is pivotable about a horizontal pivot axis to bring the upper end of the second transport means to a desired discharge height. The figures vertical and horizontal are to be understood as meaning that the mining machine stands on a horizontal ground.
Bei derartigen Abbaumaschinen kann es insbesondere bei scharfkantigem Abbaumaterial zu Beschädigungen des Transportbandes einer Transporteinrichtung kommen, die es erforderlich machen, dieses auszuwechseln.In the case of such mining machines, damage to the conveyor belt of a transport device can occur, in particular in the case of sharp-edged mining material, which makes it necessary to replace it.
Nach einem Wechsel des Transportbandes, aber auch während des Betriebs kann es erforderlich sein, das Transportband zu spannen bzw. nachzuspannen.After a change of the conveyor belt, but also during operation, it may be necessary to tension or retighten the conveyor belt.
Aus dem Stand der Technik ist es bekannt, die Achse der Antriebsrolle mit Gewindeschrauben zu verlagern. Hierzu muss sich ein Monteur zur oberen Spitze der Transporteinrichtung begeben, deren Ende sich in erheblicher Höhe befinden kann. Es versteht sich, dass damit ein erheblicher Zeitaufwand verbunden ist.From the prior art it is known to displace the axis of the drive roller with threaded screws. For this purpose, a fitter must go to the top of the transport device, the end of which can be at a considerable height. It is understood that this is associated with a considerable amount of time.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Abbaumaschine der eingangs genannten Art, sowie ein Verfahren zum Spannen eines Transportbandes einer Transporteinrichtung bei einer Abbaumaschine zu schaffen, bei denen das Spannen des Transportbandes der Transporteinrichtung mit geringem Zeitaufwand möglich ist.The invention is therefore an object of the invention to provide a mining machine of the type mentioned, and a method for tensioning a conveyor belt of a transport device in a mining machine, in which the tensioning of the conveyor belt of the transport device with little expenditure of time is possible.
Zur Lösung dieser Aufgabe dienen die Merkmale der Ansprüche 1 und 11.To achieve this object, the features of
Die Erfindung sieht in vorteilhafter Weise vor, dass die Bandspanneinrichtung fernbedienbar ausgestaltet ist. Dies hat den Vorteil, dass die Bandspanneinrichtung von einem entfernten Ort aus, am unteren Ende einer Transporteinrichtung oder am Maschinenrahmen, bedient werden kann.The invention advantageously provides that the band tensioning device is designed to be remote-controlled. This has the advantage that the belt tensioning device can be operated from a remote location, at the lower end of a transport device or on the machine frame.
Vorzugsweise besteht die Bandspanneinrichtung aus einem Fettspanner.Preferably, the belt tensioning device consists of a grease tensioner.
Die Transporteinrichtung weist ein endlos umlaufendes Transportband auf, das an den beiderseitigen Enden über eine Antriebsrolle und eine Umlenkrolle geführt ist. Die Antriebsrolle ist vorzugsweise am oberen Ende der Transporteinrichtung angeordnet und kann über die Bandspanneinrichtung zum Spannen nach außen verlagert werden.The transport device has an endlessly circulating conveyor belt, which is guided at the mutually ends via a drive roller and a deflection roller. The drive roller is preferably arranged at the upper end of the transport device and can be displaced over the belt tensioning device for clamping to the outside.
Beispielsweise kann eine Fettzuführeinrichtung für den Fettspanner vorgesehen sein, die sich über die gesamte Länge der Transporteinrichtung erstreckt, und die am unteren Ende der Transporteinrichtung oder am Maschinenrahmen einen Fettzuführanschluss aufweist, derart, dass der Fettzuführanschluss für eine auf dem Boden stehende Person zugänglich ist.For example, a grease supply device may be provided for the grease seal which extends over the entire length of the transport device and which has a grease feed connection at the lower end of the transport device or on the machine frame such that the grease supply connection is accessible to a person standing on the ground.
Im Folgenden wird unter Bezugnahme auf die Zeichnungen ein Ausführungsbeispiel der Erfindung näher erläutert.In the following an embodiment of the invention will be explained in more detail with reference to the drawings.
