Abstract

A pivot device for supporting a working device is disclosed. The pivot device has a load-bearing structure, an arm and a control rod. A first end of the arm is pivotably mounted in the load-bearing structure. The working device is pivotably connected to the second end of the arm. A first end of the control rod is hinged to the pivotable working device. A hinged quadrangle acts as a pivot point for the second end of the control rod. The quadrangle encompasses the load-bearing structure as a chassis, the arm acting as a driven element, as well as two coupling elements which close the quadrangle. The control rod is hinged, by its second end, to one of the two coupling elements. When the arm pivots, the pivot point of the second end of the control rod remains on the same side of the arm, so that the control rod does not cross the arm during pivoting.

Description

Die Erfindung betrifft eine Schwenkvorrichtung mit Ausleger, zum Verschwenken eines Arbeitsorgans zwischen einer ersten und einer zweiten Stellung, und mit einer Steuerstange zum Ausrichten des Arbeitsorgans in Abhängigkeit der Winkelstellung des Auslegers. Eine solche Vorrichtung wird zum Beispiel in einer Stichlochbohrmaschine oder Stichlochstopfmaschine am Hochofen eingesetzt.The invention relates to a swivel device with boom, for Swiveling a work organ between a first and a second Position, and with a control rod for aligning the work organ in Dependence of the angular position of the boom. Such a device will for example in a tap hole drilling machine or tap hole tapping machine on Blast furnace used.

Eine klassische Stichlochbohrmaschine weist eine Tragstruktur auf, in der ein Ausleger mit einem ersten Ende um eine erste Achse schwenkbar gelagert ist. Ein Schwenkantrieb erzeugt eine Schwenkbewegung des Auslegers um diese erste Achse, zum Beispiel aus einer Ruhestellung in eine erste Arbeitsstellung vor einem ersten Stichloch, bzw. in eine zweite Arbeitsstellung vor einem zweiten Stichloch, und jeweils zurück in die Ruhestellung. Eine Bohrlafette ist um eine zweite Achse schwenkbar mit dem zweiten Ende des Auslegers verbunden. Eine Steuerstange ist über ein erstes Gelenk mit einem Festpunkt an der Tragstruktur und über ein zweites Gelenk mit der schwenkbaren Bohrlafette verbunden, so daß eine Schwenkbewegung des Auslegers um die erste Achse, eine Schwenkbewegung der Bohrlafette um die zweite Achse erzeugt. Durch diese Steuerstange läßt sich folglich die Ausrichtung der Bohrlafette in Abhängigkeit der Winkelstellung des Auslegers festlegen.A classic tap hole drilling machine has a support structure in which a Boom with a first end is pivotally mounted about a first axis. A swivel drive creates a swiveling movement of the boom around it first axis, for example from a rest position to a first working position in front of a first tap hole, or in a second working position in front of one second tap hole, and each back to the rest position. A drill carriage is pivotable about a second axis with the second end of the boom connected. A control rod is about a first joint with a fixed point on the support structure and via a second joint with the swivel Drill mount connected so that a pivoting movement of the boom around the first axis, a pivoting movement of the drill carriage around the second axis generated. This control rod can consequently be used to align the Determine the drill carriage depending on the angular position of the boom.

Nachteilig bei diesen Schwenkvorrichtungen ist, daß die Steuerstange den Ausleger beim Verschwenken der Bohrlafette kreuzt. Hieraus erfolgt, daß diese Steuerstange entweder oberhalb oder unterhalb des Auslegers angeordnet sein muß, was natürlich den Platzbedarf (d.h. die benötigte freie Höhe) zum Verschwenken des Auslegers erhöht. Dies kann insbesondere dann zu Platzproblemen führen, wenn eine Stichlochbohrmaschine und eine Stichlochstopfmaschine auf der gleichen Seite der Abstichrinne angeordnet sind, und der Ausleger der Stichlochbohrmaschine beim Verschwenken die Stichlochstopfkanone unter- bzw. überfahren muß. Eine solche Konstellation ist zum Beispiel in der US Patentschrift 4,195,825 beschrieben. A disadvantage of these swivel devices is that the control rod Boom crosses when swiveling the drill carriage. It follows that this Control rod can be arranged either above or below the boom must, of course, what the space requirement (i.e. the required free height) for Swiveling of the boom increased. This can be especially true Space problems result when a tap hole drilling machine and a Taphole tamping machine arranged on the same side of the tapping trough are, and the boom of the tap hole drilling machine when pivoting the Taphole cannon must go under or over. Such a constellation is for example, described in U.S. Patent 4,195,825.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Schwenkvorrichtung mit Ausleger und Steuerstange zu schaffen, welche eine geringere freie Höhe zum Verschwenken des Auslegers benötigt.The present invention has for its object a To create swivel device with boom and control rod, which a less free height needed to pivot the boom.

Diese Aufgabe wird erfindungsgemäß durch eine Schwenkvorrichtung nach Anspruch 1 gelöst.This object is achieved by a swivel device Claim 1 solved.

Eine erfindungsgemäße Schwenkvorrichtung zum Tragen eines Arbeitsorgans (wie zum Beispiel eine Bohrlafette oder eine Stopfkanone) umfaßt, in bekannter Art und Weise, eine Tragstruktur, einen Ausleger und eine Steuerstange. Ein erstes Ende des Auslegers ist schwenkbar in der Tragstruktur gelagert, so daß der Ausleger relativ zur Tragstruktur um eine erste Achse schwenkbar ist. Das Arbeitsorgan ist schwenkbar am zweiten Ende des Auslegers befestigt, so daß es relativ zum Ausleger um eine zweite Achse schwenkbar ist. Die Steuerstange ist mit einem ersten Ende an dem schwenkbaren Arbeitsorgan angelenkt. Es ist ein wichtiges Merkmal der vorliegenden Erfindung, daß das zweite Ende der Steuerstange nicht wie üblich an einem Festpunkt der Tragstruktur, sondern an einem viergliedrigen Getriebe angelenkt ist. Dieses viergliedrige Getriebe umfaßt die Tragstruktur als Gestell und den Ausleger als angetriebenes Glied. Ein erstes Verbindungsglied ist an der Tragstruktur angelenkt, und ein zweites Verbindungsglied ist an dem Ausleger angelenkt. Diese beiden Verbindungsglieder sind gelenkig miteinander verbunden, so daß das viergliedrige Getriebe geschlossen ist. Die Steuerstange ist hierbei mit ihrem zweiten Ende an dem ersten oder zweiten Verbindungsglied des Getriebes angelenkt. In dieser erfindungsgemäßen Schwenkvorrichtung liegt, beim Verschwenken des Auslegers, der Anlenkpunkt des zweiten Endes der Steuerstange immer auf der gleichen Seite des Auslegers, so daß die Steuerstange den Ausleger beim Verschwenken nicht kreuzt. Hierdurch wird eine Schwenkvorrichtung geschaffen die - zumindest im Schwenkbereich der Steuerstange - eine geringere freie Höhe zum Verschwenken des Auslegers benötigt.A swivel device according to the invention for carrying a work organ (such as a drill carriage or a cannon), in known Way, a support structure, a boom and a control rod. On first end of the boom is pivotally mounted in the support structure, so that the boom is pivotable about a first axis relative to the support structure. The Work organ is pivotally attached to the second end of the boom, so that it is pivotable relative to the boom about a second axis. The Control rod is with a first end on the pivotable working member articulated. It is an important feature of the present invention that second end of the control rod is not as usual at a fixed point of the Support structure, but is hinged to a four-link gearbox. This four-link transmission includes the support structure as a frame and the boom as driven link. A first link is on the support structure hinged, and a second link is hinged to the boom. These two links are hinged together so that the four-link gearbox is closed. The control rod is included its second end on the first or second link of the Gearbox articulated. In this swivel device according to the invention, when pivoting the boom, the pivot point of the second end of the Control rod always on the same side of the boom so that the Control rod does not cross the boom when swiveling. This will created a swivel device - at least in the swivel range of the Control rod - a lower free height for pivoting the boom needed.

In Figur 1 sieht man, in einer Draufsicht auf die Gießbühne 8 eines Hochofens 12, eine Stichlochbohrmaschine 10 in Ruhestellung, seitlich von einer Abstichrinne 13 des Hochofens 12. Diese Stichlochbohrmaschine 10 besteht im wesentlichen aus einer erfindungsgemäßen Schwenkvorrichtung 14 und einer an sich bekannten Bohrlafette 16. Letztere wird hier weiter nicht beschrieben.FIG. 1 shows a top view of the casting platform 8 of a blast furnace 12, a tap hole drilling machine 10 in the rest position, to the side of one Tapping gutter 13 of the blast furnace 12. This tap hole drilling machine 10 consists in essentially from a swivel device 14 according to the invention and a well-known drill carriage 16. The latter is not described further here.

Die Schwenkvorrichtung 14 umfaßt eine Tragstruktur 18 für einen Ausleger 20. Diese Tragstruktur kann, wie in Figur 3 gezeigt, zum Beispiel unter einer Bühne 21, die den Hochofen 12 umgibt, aufgehängt sein. Sie könnte jedoch ebenfalls auf der Gießbühne 8 aufgestellt sein. Ein Ende des Auslegers 20 ist in dieser Tragstruktur 18 schwenkbar gelagert. In Figur 1 wird die Lage der Schwenkachse des Auslegers 20 in der Tragstruktur 18 durch das Bezugszeichen 22 gezeigt. An dem freien Ende des Auslegers 20 ist die Bohrlafette 16 schwenkbar aufgehängt. Die Lage der Schwenkachse der Bohrlafette 16 in dem Ausleger 20 wird durch das Bezugszeichen 24 gezeigt. Als Schwenkantrieb des Auslegers wird vorzugsweise ein Hydromotor, wie zum Beispiel ein doppeltwirkender Hydrozylinder 28, eingesetzt. Ein Ende dieses Hydrozylinders 28, in der gezeigten Ausführung handelt es sich um das Kolbenende, ist am Ausleger 20 angelenkt. Das zweite Ende des Hydrozylinder 28, in der gezeigten Ausführung handelt es sich um den Zylinderfuß, ist an der Tragstruktur 18 angelenkt. Dieser Hydrozylinder 28 ermöglicht somit ein Verschwenken des Auslegers 20 um seine Schwenkachse 22, zwischen der in der Figur 1 gezeigten Ruhestellung, abseits der Abstichrinne 13, und der in Figur 2 gezeigten Arbeitsstellung, in axialer Verlängerung des Stichlochs, direkt oberhalb der Abstichrinne 13.The pivoting device 14 comprises a support structure 18 for a boom 20. This support structure can, as shown in Figure 3, for example, under a stage 21, which surrounds the blast furnace 12, be suspended. However, it could also be set up on the casting platform 8. One end of the boom 20 is in this Support structure 18 pivotally mounted. In Figure 1, the location of the Pivot axis of the boom 20 in the support structure 18 through the Reference numeral 22 shown. At the free end of the boom 20 is the Drill mount 16 pivotally suspended. The location of the pivot axis of the Drill mount 16 in the boom 20 is shown by reference numeral 24. As a swivel drive of the boom is preferably a hydraulic motor, such as Example, a double-acting hydraulic cylinder 28 used. An end to this Hydraulic cylinder 28, in the embodiment shown, it is Piston end is articulated on the boom 20. The second end of the hydraulic cylinder 28, in the version shown it is the cylinder base, is on the Support structure 18 articulated. This hydraulic cylinder 28 thus enables Swiveling the boom 20 about its pivot axis 22, between the in the rest position shown in Figure 1, away from the tapping channel 13, and in Figure 2 shown working position, in the axial extension of the tap hole, directly above the launder 13.

Eine Steuerstange 30 ist über ein erstes Drehgelenk 32 mit der Bohrlafette 16 verbunden. In den bekannten Stichlpchbohrmaschinen ist das andere Ende dieser Steuerstange an der Tragstruktur angelenkt. Dies bedeutet, daß die Steuerstange in den bekannten Stichlochbohrmaschinen die Bohrlafette beim Verschwenken zwischen der Ruhestellung und der Arbeitsstellung kreuzt, oder in anderen Worten, daß der Ausleger die Steuerstange beim Verschwenken über- bzw. unterfahren muß. Es ist ein wichtiges Merkmal der vorliegenden Erfindung, daß das zweite Ende der Steuerstange 30, nicht an der Tragstruktur 18, sondern an einem Getriebe 34 angelenkt ist. Dieses Getriebe gewährleistet, daß die Steuerstange 30, beim Verschwenken des Auslegers 20, stets auf der gleichen Seite des Auslegers 20 liegt.A control rod 30 is connected to the drilling mount 16 via a first swivel joint 32 connected. In the well-known tap drilling machines, the other end is this control rod articulated to the support structure. This means that the Control rod in the well-known tap hole drilling machine the drill carriage Swiveling between the rest position and the working position crosses, or in other words, that the boom pivots the control rod must run over or under. It is an important feature of the present Invention that the second end of the control rod 30, not on the support structure 18, but is articulated on a gear 34. This transmission ensures that the control rod 30, when pivoting the boom 20, always on the same side of the boom 20 is.

Das Getriebe 34 wird anhand der Figuren 4 und 5 näher beschrieben. Es handelt sich um ein viergliedriges Getriebe, wobei die Tragstruktur 18 das Gestell und der Ausleger 20 das angetriebene Glied des Getriebes ausbilden. Ein erstes Verbindungsglied 36 ist über ein Drehgelenk 38 mit der Tragstruktur 18 verbunden. Ein zweites Verbindungsglied 40 ist über ein Drehgelenk 42 mit dem Ausleger 20 verbunden. Diese beiden Verbindungsglieder 36 und 40 sind über ein Drehgelenk 40 miteinander verbunden, so daß sie das viergliedrige Getriebe 34 schließen. Das zweite Ende der Steuerstange 30 ist mittels eines Drehgelenks 46 mit dem zweiten Verbindungsglied 40 des Getriebes 34 verbunden.The gear 34 is described in more detail with reference to FIGS. 4 and 5. It is a four-link transmission, the support structure 18 the Frame and the boom 20 form the driven member of the transmission. A first connecting link 36 is connected to the supporting structure via a swivel joint 38 18 connected. A second connecting member 40 is connected via a swivel joint 42 connected to the boom 20. These two links 36 and 40 are connected to each other via a swivel 40 so that they are the four-part Close transmission 34. The second end of the control rod 30 is by means of a Swivel joint 46 with the second connecting member 40 of the transmission 34 connected.

Bei einem Vergleich der Figuren 1 und 2 stellt man fest, daß beim Verschwenken des Auslegers 20, zwischen seiner Ruhe- und Arbeitsstellung, der Anlenkpunkt des zweiten Endes der Steuerstange (d.h. das Drehgelenk 46) immer auf der gleichen Seite des Auslegers 20 wie das Drehgelenk 32 liegt. A comparison of Figures 1 and 2 shows that the Pivoting the boom 20 between its rest and working position, the pivot point of the second end of the control rod (i.e. the pivot 46) always on the same side of the boom 20 as the pivot 32.

Hieraus erfolgt, daß die Steuerstange 30 den Ausleger 20 beim Verschwenken nicht kreuzt.It follows that the control rod 30 the boom 20 when pivoting does not cross.

Die genaue Ausrichtung der Bohrlafette 16 in der Arbeitsstellung wird vorteilhaft durch eine Längenverstellung der Steuerstange 30 festgelegt. Diese Längenverstellung der Steuerstange 30 kann zum Beispiel mittels einer ein- und ausschraubbaren Gewindestange 48 erfolgen.The precise alignment of the drilling mount 16 in the working position is advantageous fixed by a length adjustment of the control rod 30. This The length of the control rod 30 can be adjusted, for example, by means of a and unscrewable threaded rod 48.

Beim Verschwenken zwischen seiner Ruhe- und Arbeitsstellung, unterfährt der Ausleger 20 das erste Verbindungsglied 36. Aus den Figuren 1 und 2 erkennt man jedoch, daß der Bereich des Auslegers 20 der unter dem ersten Verbindungsglied 36 hindurch geschwenkt werden muß, auf einen relativ kurzen Abschnitt 50 in unmittelbarer Nachbarschaft der Tragstruktur 18 begrenzt ist. Wie aus Figur 3 ersichtlich, ist das Verbindungsglied 36 in diesem Abschnitt 50 in einem Freiraum zwischen der Unterseite der Bühne 21 und der Oberseite des Auslegers 20 angeordnet. Direkt hinter diesem Bereich 50, dessen Grenze in Figur 3 durch die unterbrochene Linie 52 angedeutet ist, braucht oberhalb des Auslegers 20 kein Freiraum mehr vorgesehen zu sein. Der Ausleger 20 kann folglich, wie in Figur 3 gezeigt, höhenmäßig abgestuft sein, wobei sein vorderes Ende 54 höher als sein hinteres Ende 50 liegt. Die Steuerstange 30 liegt hierbei seitlich im Schwenkbereich des vorderen Ende 54 (d.h. in einem Raum der, beim Verschwenken des Auslegers 20, zwischen Unterkante 56 und Oberkante 58 des vorderen Endes 54 des Auslegers 20 liegt). Sie beansprucht folglich beim Verschwenken keinen zusätzlichen Freiraum.When swiveling between its rest and work position, the undercarriage Cantilever 20 recognizes the first connecting link 36. From FIGS. 1 and 2 however, that the area of the boom 20 is that of the first Link 36 must be pivoted through, to a relative short section 50 in the immediate vicinity of the support structure 18 is limited. As can be seen from Figure 3, the connecting member 36 is in this Section 50 in a space between the bottom of the stage 21 and the Top of the boom 20 arranged. Right behind this area 50, the limit of which is indicated in FIG. 3 by the broken line 52, there is no longer any need to be provided above the boom 20. The boom 20 can consequently be graded in height, as shown in FIG. 3 with its front end 54 higher than its rear end 50. The Control rod 30 is located laterally in the swivel range of front end 54 (i.e. in a space that, when the boom 20 is pivoted, between Lower edge 56 and upper edge 58 of the front end 54 of the boom 20 lies). Consequently, it does not require any additional effort when pivoting Free space.

In der Figur 3 zeigt das Bezugszeichen 60 die unterhalb des Auslegers 20 verschwenkbare Stichlochstopfkanone. Es ist klar ersichtlich, daß ohne eine erfindungsgemäße Anordnung der Steuerstange 30, die freie Höhe zwischen Bühne und Gießbühne nicht ausreichend wäre, um den Ausleger 20 mit der Stichlochstopfkanone 60 zu unterfahren.In FIG. 3, reference numeral 60 shows that below the boom 20 swiveling taphole cannon. It is clearly evident that without one arrangement of the control rod 30 according to the invention, the free height between Platform and casting platform would not be sufficient to the boom 20 with the To pass under taphole cannon 60.

Abschließend ist anzumerken, daß die in den Figuren gezeigte Anordnung der Verbindungsglieder 36 und 40 lediglich eine von vielen Möglichkeiten ist. So könnten zum Beispiel diese Verbindungsglieder 36, 40 unterhalb des Auslegers 20 angeordnet sein. Es ist ebenfalls vorstellbar den Ausleger 20 im Bereich 50 mit einer Aussparung zu versehen, durch welche das Verbindungsglied 36 durchgeführt wird. In Figur 3 ist eine solche Aussparung schematisch durch eine gestrichelte Linie 62 angedeutet. In diesen beiden Fällen bräuchte der Ausleger 20 selbstverständlich nicht höhenmäßig abgestuft zu werden.In conclusion, it should be noted that the arrangement shown in the figures Links 36 and 40 is just one of many possibilities. So For example, these links 36, 40 could be below the boom 20 may be arranged.
