Description
Die Erfindung betrifft einen Schaufelradbagger zur Gewinnung von Kohle und anderen Mineralien im Tiefbau mit um eine waagerechte Achse heb-und senkbarem, ein Abförderorgan tragendem Ausleger, wobei das Abförderorgan das gewonnene Gut im Schwenkpunkt auf ein weiteres Förderorgan abgibt.The invention relates to a bucket wheel excavator for extracting coal and other minerals in civil engineering with a horizontal axis that can be raised and lowered, a discharge member carrying a boom, wherein the discharge member is the recovered material releases at the pivot point to another conveyor element.
Bei diesen bekannten Tiefbaubaggern .sind sowohl der Ausleger als auch das Schaufelrad parallel zum Streckenvortrieb angeordnet. Es ist zwar möglich, die ganze Fläche .vor Ort durch Heb- und Senkbar- sowie Schwenkbarkeit des Auslegers zu baggern, nachteilig dagegen ist, daß durch das Ausschwenken des Schaufelradauslegers der Kohlenstoß vor Ort stark ausgewölbt wird, wodurch ein großer Vorraum entsteht. Da die Bagger hauptsächlich in Verbindung mit einer wandernden Deckenstütze Anwendung finden, ist der Vorraum für die Standsicherheit der Stütze sehr nachteilig; er kann die Anwendung der Stütze überhaupt in Frage stellen. Außerdem besteht bei großem Vorraum die Gefahr des Kohleneinbruchs, namentlich bei unruhigem Gebirge, der das Baggergerät beschädigen oder gar zerstören kann.Both the boom and the the paddle wheel is also arranged parallel to the tunneling. It is possible the entire area on site thanks to the lifting, lowering and swiveling of the boom to excavate, on the other hand, it is disadvantageous that by pivoting out the bucket wheel boom the coal face is strongly bulged on site, creating a large anteroom. As the excavator is mainly used in conjunction with a moving floor prop find, the anteroom is very disadvantageous for the stability of the support; he can question the use of the prop at all. In addition, there is a large Anteroom the danger of coal ingress, especially when the mountains are unsteady Damage or even destroy the excavator equipment.
Erfindungsgemäß wird vorgeschlagen, 'den Ausleger und das Schaufelrad quer zum Streckenvortrieb sowohl anzuordnen, als auch verfahrbar durchzubilden und den Ausleger um seine Schwenkachse um etwa 36o° zu schwenken. Durch diese Anordnung kommt die Wölbung am Stoß ganz in Fortfall, und es entsteht vor Ort eine glatte Wand, die dicht vor den oberen Druckplatten der Deckenstütze abschließt.According to the invention it is proposed 'the boom and the paddle wheel to be arranged transversely to the drifting, as well as designed to be movable and to pivot the boom about its pivot axis by about 36o °. Through this arrangement the bulge at the joint disappears completely, and a smooth one is created on site Wall that ends close to the upper pressure plates of the ceiling prop.
Nach einem weiteren Erfindungsgedanken ist die Schwenkachse des Auslegers samt dem Antrieb des Schaufelrades und des im Ausleger angeordneten Förderers höhenverstellbar gelagert, beispielsweise auf einer mittels Spindelgetriebes verstellbaren Schwinge. Dies ist namentlich beim Umschwenken des Schaufelradauslegers von besonderem Vorteil.According to a further idea of the invention, the pivot axis of the boom including the drive of the paddle wheel and the conveyor arranged in the boom are height-adjustable stored, for example on a rocker arm adjustable by means of a spindle drive. This is particularly advantageous when swiveling the bucket wheel arm.
Ferner wird vorgeschlagen, den Auslauf der Kohle aus dem Abförderorgan des Auslegers über einen seitlich austragenden Trichter zu bewerkstelligen, so daß bei jeder Stellung des Auslegers eine einwandfreie Materialübergabe an die Abförderung erfolgt.It is also proposed that the coal discharge from the discharge device to accomplish the boom over a laterally discharging funnel, so that in every position of the boom, a perfect material transfer to the conveying system he follows.
Schließlich wird noch vorgeschlagen, die Achse des Schaufelradauslegers geneigt zur Horizontalen anzuordnen, so daß hierdurch eine nach vorn geneigte Stirnfläche beim Vortrieb erhalten wird. Dadurch gewinnt der von der Deckenstütze unabhängige Bagger mehr Bewegungsfreiheit. Auch wird die Kohle teilweise unterschnitten, was die nachfolgende Baggerarbeit erleichtert.Finally, it is proposed that the axis of the bucket wheel arm to be arranged inclined to the horizontal, so that this results in a forwardly inclined face is obtained during the advance. As a result, the independent from the floor prop wins Excavator more freedom of movement. The coal is also partially undercut, what the subsequent excavation work is facilitated.
In der Zeichnung ist das Wesen der Erfindung beispielsweise veranschaulicht, und zwar zeigt Fig. i eine Seitenansicht und Fig.2 eine Vorderansicht. Auf dein Baggeruntergestell i, welches vorn zwei Schreitwerke 2 und hinten eine leer laufende und lenkbare Gleiskette 3 aufweist, lagert quer zum Arbeitsfortschritt verfahrbar das obere Baggergeriist .1. Das Baggergeriist 4 trägt eine um einen waagerechten Zapfen 5 mittels eines Spindelantriebes 7 höhenverstellbare Schwinge 6, auf welcher andererseits die Schwenkachse 8 des ein Abförderorgan 9 und ein Schaufelrad i i tragenden Auslegers io angeordnet ist. Die Schwenkachse 8 ist etwas zur Horizontalen geneigt angeordnet und liegt außerdem in Fahrtrichtung.In the drawing, the essence of the invention is illustrated, for example, namely FIG. 1 shows a side view and FIG. 2 shows a front view. To your Excavator frame i, which has two walking mechanisms 2 in front and an empty one in the back and has steerable crawler belt 3, stored transversely to the progress of work the upper excavator is .1. The Baggergeriist 4 carries one around a horizontal one Pin 5 by means of a spindle drive 7 height-adjustable rocker 6, on which on the other hand, the pivot axis 8 of a discharge element 9 and a paddle wheel i i supporting boom io is arranged. The pivot axis 8 is somewhat to the horizontal inclined and also lies in the direction of travel.
Der Ausleger io wird vom Motor 12 aus über ein Getriebe 13 in alle erforderlichen Arbeitslagen gebracht und gehalten, während der Antrieb des Schaufelrades unddes im Ausleger angeordneten Abförderorgans über. ein Getriebe 14 vom Motor 15 aus erfolgt.The boom io is from the engine 12 via a gear 13 in all necessary working positions brought and held while driving the paddle wheel andthe discharge element arranged in the boom. a transmission 14 from engine 15 off takes place.
Das vom Schaufelrad i i gewonnene und mittels Abförderorgans 9 weitergeleitete Gut wird in der Schwenkachse 8 über einen seitlich austragenden Trichter 16 auf ein weiteres Förderorgan 17 abgegeben, wo es dann schließlich wahlweise auf das Streckenband oder die Schüttelrutsche 18 abgegeben wird.That obtained from the paddle wheel i i and passed on by means of the discharge element 9 Well is in the pivot axis 8 via a laterally discharging funnel 16 another conveyor member 17 delivered, where it then finally optionally on the Stretch belt or the shaking chute 18 is released.
