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

Schwenkvorrichtung mit Ausleger und Steuerstange Swivel device with boom and control rod
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 working member between a first and a second position, and with a control rod for aligning the working member as a function of the angular position of the boom. Such a device is used, for example, in a tap hole drilling machine or tap hole tamping machine on the blast furnace.
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 generates a swiveling movement of the boom about this first axis, for example from a rest position into a first working position in front of a first tap hole, or into a second working position in front of a second tap hole, and in each case back into the rest position. A drill carriage is pivotally connected to the second end of the boom about a second axis. A control rod is connected via a first joint to a fixed point on the supporting structure and via a second joint to the pivotable drill carriage, so that a pivoting movement of the boom about the first axis produces a pivoting movement of the drill carriage about the second axis. With this control rod, the alignment of the drill carriage depending on the angular position of the boom can thus be determined.
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. 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.A disadvantage of these pivoting devices is that the control rod crosses the boom when pivoting the drill carriage. From this it follows that this control rod must be arranged either above or below the boom, which of course increases the space required (ie the required free height) for pivoting the boom. This can lead to space problems in particular if a tap hole drilling machine and a tap hole tamping machine are arranged on the same side of the tapping channel and the boom of the tap hole drilling machine has to pass under or over the tap hole tamping cannon when pivoting. Such a constellation is described, for example, in US Pat. No. 4,195,825. The present invention has for its object to provide a pivoting device with boom and control rod, which requires a lower free height for pivoting the boom.
Diese Aufgabe wird erfindungsgemäß durch eine Schwenkvorrichtung nach Anspruch 1 gelöst.This object is achieved by a swivel device according to claim 1.
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. Ein Ausführungsbeispiel der Erfindung wird anhand der beiliegenden Zeichnungen näher beschrieben. Es zeigt: Figur 1 : eine Draufsicht auf eine Stichlochbohrmaschine mit einer erfindungsgemäßen Schwenkvorrichtung, in Ruhestellung vor einem Hochofen;A swiveling device according to the invention for carrying a work organ (such as, for example, a drill carriage or a stuffing gun) comprises, in a known manner, a support structure, a boom and a control rod. A 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 working member 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 articulated with a first end on the pivotable working member. It is an important feature of the present invention that the second end of the control rod is not articulated at a fixed point on the support structure, but rather at a four-link transmission. This four-link gear comprises the support structure as a frame and the boom as a driven link. A first link is hinged to the support structure and a second link is hinged to the boom. These two connecting links are connected to one another in an articulated manner, so that the four-link transmission is closed. The control rod is articulated with its second end to the first or second connecting element of the transmission. In this swivel device according to the invention, when pivoting the boom, the articulation point of the second end of the control rod is always on the same side of the boom, so that the control rod does not cross the boom when pivoting. This creates a swivel device which - at least in the swivel range of the control rod - requires a smaller free height for swiveling the boom. An embodiment of the invention will be described with reference to the accompanying drawings. It shows: Figure 1 is a plan view of a tap hole drilling machine with a swivel device according to the invention, in the rest position in front of a blast furnace;

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.1 shows, in a plan 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 a tapping channel 13 of the blast furnace 12. This tap hole drilling machine 10 essentially consists of a swivel device 14 according to the invention and a drilling mount 16 known per se The latter is not further described 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 FIG. 3, be suspended, for example, under a platform 21 which surrounds the blast furnace 12. However, it could also be set up on the casting platform 8. One end of the boom 20 is pivotally mounted in this support structure 18. In Figure 1, the position of the pivot axis of the boom 20 in the support structure 18 is shown by the reference numeral 22. At the free end of the boom 20, the drill carriage 16 is pivotally suspended. The position of the pivot axis of the drill carriage 16 in the boom 20 is shown by the reference numeral 24. A hydraulic motor, such as a double-acting hydraulic cylinder 28, is preferably used as the pivot drive of the boom. One end of this hydraulic cylinder 28, in the embodiment shown it is the piston end, is articulated on the boom 20. The second end of the hydraulic cylinder 28, in the embodiment shown is the cylinder base, is on the Support structure 18 articulated. This hydraulic cylinder 28 thus enables the boom 20 to be pivoted about its pivot axis 22, between the rest position shown in FIG. 1, away from the tapping channel 13, and the working position shown in FIG. 2, in an axial extension of the tap hole, directly above the tapping channel 13.
Eine Steuerstange 30 ist über ein erstes Drehgelenk 32 mit der Bohrlafette 16 verbunden. In den bekannten Stichlochbohrmaschinen 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. In the known tap hole drilling machines, the other end of this control rod is articulated on the support structure. This means that the control rod in the known tap hole drilling machine crosses the drilling carriage when pivoting between the rest position and the working position, or in other words that the boom must pass over or under the control rod when pivoting. It is an important feature of the present invention that the second end of the control rod 30 is articulated not on the support structure 18 but on a gear 34. This gear ensures that the control rod 30 is always on the same side of the boom 20 when the boom 20 is pivoted.
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-part transmission, the support structure 18 forming the frame and the boom 20 the driven member of the transmission. A first connecting member 36 is connected to the support structure 18 via a swivel joint 38. A second connecting member 40 is connected to the boom 20 via a swivel joint 42. These two connecting links 36 and 40 are connected to one another via a swivel joint 40, so that they close the four-link transmission 34. The second end of the control rod 30 is connected to the second connecting member 40 of the transmission 34 by means of a swivel joint 46.
Bei einem Vergleich der Figuren 1 und 2 stellt man fest, daß beimA comparison of Figures 1 and 2 shows that the
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. Hieraus erfolgt, daß die Steuerstange 30 den Ausleger 20 beim Verschwenken nicht kreuzt.Swiveling the boom 20, between its rest and working position, the pivot point of the second end of the control rod (ie the pivot joint 46) is always on the same side of the boom 20 as the pivot joint 32. It follows from this that the control rod 30 does not cross the boom 20 when pivoting.
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 exact alignment of the drill carriage 16 in the working position is advantageously determined by adjusting the length of the control rod 30. This length adjustment of the control rod 30 can take place, for example, by means of a threaded rod 48 that can be screwed in and out.
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 pivoting between its rest and working position, the boom 20 moves under the first connecting link 36. However, it can be seen from FIGS. 1 and 2 that the area of the boom 20 that has to be pivoted under the first connecting link 36 has a relatively short section 50 in the immediate vicinity of the support structure 18 is limited. As can be seen from FIG. 3, the connecting link 36 is arranged in this section 50 in a free space between the underside of the stage 21 and the upper side of the boom 20. Directly behind this area 50, the border of which is indicated in FIG. 3 by the broken line 52, there is no longer any need to be provided above the arm 20. The boom 20 can consequently be stepped in height, as shown in FIG. 3, its front end 54 being higher than its rear end 50. The control rod 30 is located laterally in the pivoting range of the front end 54 (i.e. in a space which, when the boom 20 is pivoted, lies between the lower edge 56 and the upper edge 58 of the front end 54 of the boom 20). Consequently, it does not take up any additional space when pivoting.
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 the tap hole cannon which can be pivoted below the boom 20. It is clearly evident that without an arrangement of the control rod 30 according to the invention, the free height between the platform and the casting platform would not be sufficient to drive under the boom 20 with the tap hole 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 brauchte der Ausleger 20 selbstverständlich nicht höhenmäßig abgestuft zu werden. In conclusion, it should be noted that the arrangement of the connecting members 36 and 40 shown in the figures is only one of many possibilities. For example, these links 36, 40 could be below the boom 20 may be arranged. It is also conceivable to provide the arm 20 in the area 50 with a recess through which the connecting member 36 is passed. Such a recess is indicated schematically by a broken line 62 in FIG. In these two cases, the boom 20 naturally did not need to be graduated in height.
