Description

Die Erfindung betrifft einen Schiebeverschluss nach dem Oberbegriff des Anspruchs 1.The invention relates to a sliding closure according to the preamble of Claim 1.

Bei einem Apparat gemäss der Druckschrift US-A-4 116 372 ist ein am Gehäuse schwenkbar gelagerter Deckel vorgesehen, der von Spannelementen verschliessbar ist. Der Deckel ist jedoch zum Gehäuse derart verspannt, dass er keine Anpassungen relativ zu diesem während des Betriebes zulässt, die beispielsweise durch Wärmedehnungen hervorgerufen werden.In an apparatus according to US-A-4 116 372 there is one on the housing pivoted lid provided by clamping elements is lockable. However, the cover is clamped to the housing in such a way that it does not allow any adjustments relative to this during operation that for example caused by thermal expansion.

Ausserdem ist an letzterer ein feuerfestes Giessrohr angeschlossen, welches von einer Wechselvorrichtung gehalten und an diese Unterplatte angepresst ist. Der die feuerfeste Oberplatte aufnehmende Deckel bewirkt über ein Verspannorgan eine Anpressung dieser Oberplatte an die Schieberplatte. Dieser Deckel ist dabei von einer Schraube als Arretiermittel gegen ein Verschieben in Bewegungsrichtung der Schieberplatte fixiert. Hierbei ist nachteilig, dass sich die Schrauben durch das in der Regel oszillierende Hin- und Herschieben der Schieberplatte lösen können, weil diese Schieberplatte eine vibrationsartige Rüttelbewegung auf den Deckel erzeugt. Ausserdem kann sich der Deckel in Höhenrichtung nicht verstellen, um quer zur Verschieberichtung entstehende Wärmedehnungen oder anderweitige Verschiebungen auszugleichen.In a generic device according to EP-B1-0 441 927 includes a slide lock, which is a fire-resistant top plate, a lid holding this, a fireproof slide plate and a fixed one has fireproof base plate. In addition, the latter is fireproof Pouring tube connected, which by a changing device is held and pressed against this lower plate. The fireproof top plate receiving cover causes a pressure via a tensioning element this top plate to the slide plate. This lid is from one Screw as a locking means against moving in the direction of movement Slider plate fixed. The disadvantage here is that the screws solve the usually oscillating back and forth of the slide plate can, because this slide plate vibrates like a vibration created the lid. In addition, the lid cannot move vertically adjust in order to prevent thermal expansions occurring transversely to the direction of displacement or to compensate for other shifts.

Der vorliegenden Erfindung wurde demgegenüber die Aufgabe zugrundegelegt, einen Schiebeverschluss nach der eingangs erwähnten Gattung derart weiterzubilden, dass mit ihm bei einfacher Konstruktion einerseits eine betriebssichere Blockierung des Deckels in Verschieberichtung der Schieberplatte und andererseits senkrecht dazu eine zumindest beschränkte Verstellbarkeit gewährleistet ist.The present invention was based on the object a sliding closure according to the type mentioned above to further develop that with a simple design, on the one hand, it is reliable Blocking of the cover in the direction of displacement of the slide plate and on the other hand perpendicular to it an at least limited adjustability is guaranteed.

Die Aufgabe ist erfindungsgemäss nach dem Kennzeichen des Anspruchs 1 gelöst.According to the invention, the object is according to the characterizing part of claim 1 solved.

Senkrecht zur Verstellrichtung der Schieberplatte ist der Deckel indessen nicht starr befestigt und er ist daher im Stande, Wärmedehnungen ausgleichen.By means of this locking means provided according to the invention, the cover is in the Operation fixed at all times and not limited to one mounting position. The cover is perpendicular to the direction of adjustment of the slide plate meanwhile not rigidly attached and therefore it is capable of thermal expansion compensate.

Bei einer weiteren erfindungsgemässen Ausführung ist bei einem Schiebeverschluss mit einer Giessrohrwechselvorrichtung der auf der Oberseite des Gehäuses angeordnete Deckel schwenkbar an diesem Gehäuse gelagert und Spannelemente zum Aneinanderpressen der Verschlussplatten sind insbesondere paarweise beidseitig zum Deckel angeordnet und als am Gehäuse schwenkbare Spannschrauben ausgebildet. Dies ermöglicht eine einfache Montage bzw. Demontage dieses Schiebeverschlusses, welcher überdies in seiner Funktion betriebssicher ausgebildet ist.In a further embodiment according to the invention, there is a sliding closure with a pouring tube changing device on the top of the Housing arranged cover pivotally mounted on this housing and Clamping elements for pressing the closure plates against one another are in particular arranged in pairs on both sides of the lid and as on the housing swiveling clamping screws.

Fig.1 zeigt einen Schiebeverschluss 10, welcher unten am Ausguss eines andeutungsweise veranschaulichten Behälters 14 montiert ist, wobei es sich beim Behälter vorzugsweise um ein Verteilergefäss einer Stranggiessanlage handelt. An der Unterseite des Schiebeverschlusses 10 ist überdies eine Giessrohrwechselvorrichtung 40 vorgesehen, welche ein feuerfestes Giessrohr 42 hält, das insbesondere in eine Stranggiesskokille ragt und ein verdecktes Giessen der Metallschmelze vom Verteilergefäss in diese Kokille ermöglicht.1 shows a sliding closure 10, which is indicated at the bottom of the spout illustrated container 14 is mounted, wherein it in the case of the container, preferably around a distributor vessel of a continuous caster is. On the underside of the slide closure 10 is also a Pouring tube changing device 40 is provided, which is a refractory pouring tube 42 holds, which protrudes in particular in a continuous casting mold and a hidden one Pour the molten metal from the distribution vessel into this mold allows.

Der Schiebeverschluss 10 weist ein an den Behälter 14 befestigbares Gehäuse 12 auf, welches zu diesem Zwecke auf der Oberseite vorstehende Auflageflächen 16 hat, die am äusseren Stahlmantel des Behälters 14 anliegen. Im Gehäuse 12 sind eine obere und eine untere feststehende feuerfeste Verschlussplatte 22, 24 sowie eine zwischen diesen von einem nicht näher gezeigten Antrieb hin- und her bewegbare Schieberplatte 23 aufgenommen. Die feststehenden Verschlussplatten 22, 24 sind über Befestigungsmittel 26 in einem Deckel 15 bzw. im Gehäuse 12 fixiert, währenddessen die Schieberplatte 23 in einem mit dem Antrieb gekoppelten Metallrahmen 27 befestigt ist. Diese feuerfesten Platten 22, 23, 24 weisen jeweils eine Durchgangsöffnung 18 auf, durch die in der gezeigten Offenstellung Metallschmelze aus dem Behälter 12 abgegossen wird. Durch eine Längsbewegung dieser Schieberplatte 23 kann der Auslass gedrosselt oder geschlossen werden. Diese Platte dient aber insbesondere auch als Stellglied für ein geregeltes Abgiessen der Schmelzenmenge aus dem Behälter 12.The sliding closure 10 has a housing which can be fastened to the container 14 12, which for this purpose on the top protruding bearing surfaces 16 has, which rest on the outer steel jacket of the container 14. in the Housing 12 are an upper and a lower fixed refractory closure plate 22, 24 and one between them by a not shown Drive reciprocally movable slide plate 23 added. The fixed closure plates 22, 24 are via fastening means 26 fixed in a cover 15 or in the housing 12, meanwhile, the slide plate 23 fastened in a metal frame 27 coupled to the drive is. These refractory plates 22, 23, 24 each have a through opening 18, by the molten metal in the open position shown is poured out of the container 12. By a longitudinal movement this slide plate 23, the outlet can be throttled or closed. This plate also serves in particular as an actuator for a regulated Pour the amount of melt out of the container 12.

An die untere im Gehäuse 12 feststehende Verschlussplatte 24 schliesst das in der Wechselvorrichtung 40 aufgenommene Giessrohr 42 an, welches von andeutungsweise dargestellten Kipphebeln 44 auf an sich bekannte Art und Weise an diese Platte 24 angepresst wird. Dieses Giessrohr 42 kann senkrecht zur Bildebene über einen nicht näher gezeigten Antrieb verschoben und durch ein neues Giessrohr ersetzt werden.This closes the lower closure plate 24 fixed in the housing 12 pouring pipe 42 received in the changing device 40, which of indicated rocker arms 44 in a manner known per se and Is pressed against this plate 24. This pouring tube 42 can be vertical shifted to the image plane via a drive, not shown and be replaced by a new pouring tube.

Auf der dem Behälter 14 zugekehrten Seite ist oben am Gehäuse 12 der Deckel 15 vorgesehen, welcher vom Gehäuse weggenommen werden kann, wenn der Schiebeverschluss 10 vom Behälter demontiert ist. Hierdurch können nach Öffnung dieses Deckels 15 die feuerfesten Verschlussplatten 22, 23, 24 ausgewechselt werden. Diese Vorsehung des Deckels 15 auf der Gehäuseoberseite bedingt, dass der Schiebeverschluss 10 mit jedem Wechsel dieser Platten vom Behälter abmontiert wird. On the side facing the container 14, the top of the housing 12 is the Cover 15 is provided, which can be removed from the housing, when the slide closure 10 is removed from the container. This can after opening this cover 15, the refractory closing plates 22, 23, 24 to be replaced. This provision of the cover 15 on the top of the housing conditioned that the slide lock 10 with each change these plates are removed from the container.

Erfindungsgemäss ist ein Arretiermittel 20 zum Blockieren des Deckels 15 vorgesehen, welches derart ausgebildet ist, dass es im Betrieb bei einer Positionsänderung des Deckels 15 in Verschieberichtung der Schieberplatte 23 selbsttätig nacharretiert, damit der Deckel stets blockiert ist, indes dieses Arretiermittel 20 eine auftretende Verstellung des Deckels 15 senkrecht zur Verschieberichtung zulässt.According to the invention, a locking means 20 for blocking the cover 15 provided, which is designed such that it is in operation when a position change of the cover 15 in the direction of displacement of the slide plate 23 automatically locked so that the cover is always blocked, but this one Locking means 20 an occurring adjustment of the lid 15 perpendicular to Allows displacement direction.

Zu diesem Zwecke weist das Arretiermittel 20 zwei am Gehäuse 12 um eine Drehachse 25A gelagerte Schwenkzapfen 25 auf, welche am Aussenmantel 25' spiralförmig ausgebildet sind und mit dem Deckel punkt- oder vorzugsweise linienförmig in Kontakt stehen. Sie sind dabei an einer Achse 29 gehalten, an der mindestens ein seitlich wegragender Schwenkhebel 21 befestigt ist, der in arretiertem Zustand eine vom Deckel 15 abgekehrte, annähernd horizontale Lage einnimmt. Der von der Drehachse 25A zum Aussenmantel 25' gebildete Radius beim jeweiligen Schwenkzapfen 25 vergrössert sich in entgegengesetzter Richtung zur Drehrichtung des Schwenkhebels 21 beim Arretieren. Dadurch wird die selbsttätige Verspannwirkung der Schwenkzapfen 21 auf den Deckel 15 durch das Eigengewicht dieses Schwenkhebels 21 erzeugt. Zur Erzielung der gleichen Wirkung könnte der Schwenkzapfen im Prinzip auch zylindrisch ausgebildet und dabei exzentrisch an der Achse 29 gelagert sein.For this purpose, the locking means 20 has two on the housing 12 by one Axis of rotation 25A mounted pivot pin 25, which on the outer jacket 25 'are formed spirally and point or preferably with the lid are in line contact. They are held on an axis 29 attached to the at least one laterally projecting pivot lever 21 is, in the locked state, a remote from the lid 15, approximately occupies a horizontal position. The one from the axis of rotation 25A to the outer jacket 25 'formed radius at the respective pivot pin 25 enlarged in the opposite direction to the direction of rotation of the pivot lever 21 when locking. This will automatically tighten the Swivel pin 21 on the lid 15 by its own weight Swivel lever 21 generated. To achieve the same effect, the In principle, the pivot pin is also cylindrical and eccentric be mounted on the axis 29.

Mit der oben erläuterten Ausbildung des Arretiermittels 20 ergibt sich im Rahmen der Erfindung ein weiterer Vorteil, als der Schwenkhebel 21 durch eine Handbewegung ohne Werkzeug in Arretier- bzw. in Öffnungsstellung 21' gebracht werden kann und eine verlässliche Blockierung gewährleistet. Des weiteren ist dieser Schwenkhebel 21 mit einer solchen Länge ausgebildet, dass er im angebauten Zustand des Schiebeverschlusses 10 am Behälter 14 nicht in dieser Öffnungsstellung 21' sein kann, sondern sich selbsttätig in die Arretierstellung begibt.With the above-described design of the locking means 20 results in Another advantage of the invention than the pivot lever 21 through a hand movement without tools in the locking or open position 21 'can be brought and ensures a reliable blocking. Furthermore, this pivot lever 21 is formed with such a length that he is in the attached state of the slide closure 10 on the container 14 can not be in this open position 21 ', but in itself releases the locking position.

An der Unterseite des Deckels 15 sind überdies zwei Nocken 38 vorgesehen, welche bei geschlossenem Deckel 15 annähernd spielfrei in entsprechende Nuten im Gehäuse 12 eingreifen. Der Deckel 15 ist damit in Verschieberichtung der Platte 23 zentriert. Eine im Betrieb üblicherweise vorgesehene oszillierende Bewegung der Platte 23 wird durch die durch Spannelemente aneinandergepressten Platten 22, 23 auf den Deckel 15 übertragen. Mit dem Arretiermittel 20 ist jedoch sichergestellt, dass der Deckel 15 auch nach mehreren Stunden Betriebszeit eine starre Position einnimmt, damit die Mörtelverbindung zwischen der Hülse 11 und der oberen Verschlussplatte 22 nicht zerstört wird.On the underside of the cover 15, two cams 38 are also provided, which with the lid 15 closed almost without play in corresponding Engage grooves in the housing 12. The cover 15 is thus in the direction of displacement the plate 23 centered. An oscillating one usually provided during operation Movement of the plate 23 is caused by the clamping elements pressed together plates 22, 23 transferred to the cover 15. With the Locking means 20 is ensured, however, that the lid 15 also after takes up a rigid position for several hours of operation so that the Mortar connection between the sleeve 11 and the upper closure plate 22 is not destroyed.

Fernerhin ist am Gehäuse 12 eine Halterung 35 auf der gegenüberliegenden Seite zum Arretiermittel 20 für den nicht gezeigten Antrieb angeordnet. Diese Halterung 35 ist über ein Scharnier 36 seitlich wegschwenkbar am Gehäuse 12 gelagert.Furthermore, on the housing 12 there is a holder 35 on the opposite one Arranged side to the locking means 20 for the drive, not shown. This Bracket 35 can be pivoted away laterally on the housing via a hinge 36 12 stored.

Gemäss Fig.2 und Fig.3 ist bei einer weiteren sehr vorteilhaften Ausführung des Schiebeverschlusses 10 erfindungsgemäss der die obere feuerfeste Verschlussplatte 22 aufnehmende Deckel 15 schwenkbar am Gehäuse 12 gelagert und die Spannelemente sind insbesondere paarweise beidseitig zum Deckel 15 angeordnet und als am Gehäuse 12 schwenkbare Spannschrauben 33 ausgebildet. Letztere sind seitlich in eine Ausnehmung des Deckels 15 einschwenkbar und sie üben nach deren Festziehen eine Verspannung auf die Verschlussplatten aus. Zweckmässigerweise ist der Deckel 15 seitlich an Schwenkzapfen 39 des Gehäuses 12 gelagert und seine Schwenkachse 15A in gleicher Richtung wie die Verschieberichtung der Schieberplatte 23 ausgerichtet. Hierdurch kann dieser rechteckförmige Deckel um seine schmale Seite aufgeschwenkt werden. Auf der gegenüberliegenden Seite ist am Dekkel 15 ferner noch ein Handgriff 34 vorgesehen, mittels dem der Deckel leicht geöffnet werden kann.According to Fig. 2 and Fig. 3 is another very advantageous embodiment of the sliding closure 10 according to the invention the upper refractory closure plate 22 receiving cover 15 pivotally mounted on the housing 12 and the clamping elements are in particular on both sides in pairs Cover 15 arranged and as pivotable on the housing 12 clamping screws 33 trained. The latter are laterally in a recess in the cover 15 can be swiveled in and after tightening they exert tension the closing plates. The cover 15 is expediently on the side The pivot pin 39 of the housing 12 is mounted and its pivot axis 15A aligned in the same direction as the direction of displacement of the slide plate 23. This allows this rectangular lid to be narrow Side can be swung open. On the opposite side is on the lid 15 further provided a handle 34, by means of which the lid can be opened easily.

Als weitere vorteilhafte Ausbildung sind die Spannschrauben 33 in dem Bereich des Gehäuses 12 gelagert, der nach unten hin offen ist und durch die längliche Ausnehmung 45 in der Giessrohrwechselvorrichtung gebildet ist, durch welche das Giessrohr 42 mit seinem oberen plattenförmigen Ende durchführbar ist. Diese Spannschrauben 33 können somit einfach ins Gehäuse 12 montiert bzw. aus diesem ausgewechselt werden. Die längliche Ausnehmung 45 ist mithin quer zur Verschieberichtung der Schieberplatte 23 ausgebildet.As a further advantageous embodiment, the clamping screws 33 are in the area of the housing 12 mounted, which is open at the bottom and through the elongated recess 45 is formed in the pouring tube changing device, through which the pouring tube 42 with its upper plate-shaped end is feasible. These clamping screws 33 can thus easily be in the housing 12 can be installed or replaced. The elongated recess 45 is therefore transverse to the direction of displacement of the slide plate 23 educated.

Fig.4 und Fig.5 zeigen einen Schiebeverschluss 50, der vom Aufbau her demjenigen nach Fig.1 entspricht und daher nurmehr in den unterschiedlichen Einzelheiten erläutert ist. Als wesentliches Unterscheidungsmerkmal fehlt der Giessrohrwechsler. Der Deckel 55 ist dementsprechend auf der Unterseite des Gehäuses 52 angeordnet und seine Schwenkachse 55A verläuft quer zur Verschieberichtung der Schieberplatte 23.Fig. 4 and Fig. 5 show a slide closure 50, the construction corresponds to that of Figure 1 and therefore only in the different Details are explained. As a key differentiator the pouring tube changer is missing. The lid 55 is accordingly on the Arranged underside of the housing 52 and its pivot axis 55A extends transverse to the direction of displacement of the slide plate 23.

Bei diesem Schiebeverschluss 50 ist erfindungsgemäss wiederum ein Arretiermittel 60 vorgesehen, mittels dem der Deckel 55 blockierbar ist. Dieses Arretiermittel 60 ist hierbei mit zwei an einer Achse 55A befestigten Schwenkzapfen 65 versehen, welche in gleicher Weise wie diejenigen nach Fig.1 auf den Deckel 55 einwirken. Die Achse 55A ist an zwei Lageraugen 52' des Gehäuses 52 drehbar gehalten und hat endseitig einen entsprechenden Schwenkhebel 61, der in arretiertem Zustand - wie dargestellt - eine annähernd horizontale Lage einnimmt. According to the invention, this sliding closure 50 is again a locking means 60 is provided, by means of which the cover 55 can be blocked. This Locking means 60 is in this case fastened with two to an axis 55A Provide pivot pin 65, which in the same way as those after Fig.1 act on the cover 55. The axis 55A is on two bearing eyes 52 'of the housing 52 is rotatably held and has a corresponding end Swivel lever 61, which in the locked state - as shown - approximately occupies a horizontal position.

Als weiteres besonderes Merkmal ist im Rahmen der Erfindung der schwenkbare Deckel 55 an derselben Achse 55A wie das Arretiermittel 60 gehalten. Der Deckel 55 weist dazu endseitig eine Lagerbüchse 55' auf, durch welche sich mit Spiel diese Achse 55A erstreckt. Ausserdem sind einerseits seitlich am Deckel 55 und andererseits an der Achse 55A gelagerte Lenkhebel 66 vorgesehen, mittels denen sich der Deckel 55 im gezeigten Betriebszustand senkrecht zu seiner Längserstreckung für den Ausgleich von Wärmeausdehnungen oder ähnlichem verstellen kann. Damit ist ein wirksames Mittel für eine sichere Blockierung des Deckels während des Betriebes geschaffen worden.Another special feature of the invention is the hinged cover 55 on the same axis 55A as the locking means 60 held. To this end, the cover 55 has a bearing bush 55 'at the end, through which this axis 55A extends with play. In addition, on the one hand laterally mounted on the cover 55 and on the other hand on the axis 55A Steering lever 66 is provided, by means of which the cover 55 in the shown Operating state perpendicular to its longitudinal extent for the compensation of Can adjust thermal expansion or the like. This is an effective one Means for a secure locking of the cover during operation been created.

Die Erfindung ist mit den beiden oben erläuterten Ausführungsbeispielen ausreichend dargetan. Selbstverständlich liesse sich die Erfindung konstruktiv noch anders ausführen.The invention is based on the two exemplary embodiments explained above adequately demonstrated. Of course, the invention could be constructed run differently.
