Abstract

The invention refers to a brick lining apparatus for metallurgical vessels, particularly for steel mill converters and/or blast furnaces, with an annular working platform which is automatically adjustable in height, and with a coordinated brick conveyor line consisting of one or several chains leading around sprocket wheel pairs with attached brick supports, whereby working platform and brick conveyor line are retractable to approximately the distance between mill floor and vessel opening.

Description

Die Erfindung betrifft eine Ausmauerungseinrichtung für metallurgische Gefäße, insbesondere für Stahlwerkskonverter und/oder Hochöfen, die eine selbständig höhenverstellbare, ringförmige Arbeitsplattform und eine dieser zugeordnete vertikale Steinförderstrecke, bestehend aus einer oder mehreren um Kettenradpaare geführte Ketten mit an diesen befestigten Steinauflagen, aufweist, wobei Arbeitsplattform und Steinförderstrecke etwa auf den Abstand zwischen Hüttenflur und Gefäßöffnung einziehbar sind.The invention relates to a lining device for metallurgical vessels, in particular for steelwork converters and / or blast furnaces, which has an independently height-adjustable, ring-shaped working platform and a vertical stone conveying path associated therewith, consisting of one or more chains guided around pairs of sprockets with stone supports attached to them, whereby working platform and stone conveying section are retractable approximately to the distance between the hut floor and the vessel opening.

Derartige Einrichtungen dienen dazu, die Zustellungarbeit in metallurgischen Gefäßen zu erleichtern, die Zustellungszeiten zu vermindern und die Ausmauerungsleistung zu erhöhen. Diese Bedingungen können nur durch einen kontinuierlichen Transportfluß der Steine auf horizontalen und vertikalen Steinförderstrecken erfüllt werden. Durch Automatisierung des Steintransports sollen außerdem Arbeitskräfte eingespart bzw. für die Arbeiten auf der Arbeitsplattform freigemacht werden.Devices of this type serve to facilitate the delivery work in metallurgical vessels, to reduce delivery times and to increase the lining performance. These conditions can only be met by a continuous flow of stones in horizontal and vertical stone transport routes. Automation of the stone transport should also save workers or free them up for work on the work platform.

Aus der DE-OS 15 33 903 ist eine selbständig höhenverstellbare, ringförmige Arbeitsplattform bekannt, wobei die Arbeitsplattform etwa auf den Abstand zwischen Hüttenflur und Gefäßbodenöffnung einziehbar ist. Die vertikale Steinförderstrecke besteht dort aus einem Aufzugkäfig, mit dem die Steine ladungsweise auf die Arbeitsplattform befördert werden.From DE-OS 15 33 903 an independently height-adjustable, ring-shaped work platform is known, the work platform being retractable approximately to the distance between the hut floor and the vessel bottom opening. The vertical stone conveyor line there consists of an elevator cage with which the stones are loaded onto the work platform.

Gemäß der älteren, unveröffentlichten DE-Patentanmeldung P 29 14 651.8 ist zwecks Bildung einer vertikalen Steinförderstrecke bereits vorgeschlagen worden, an einer oder mehreren um Kettenradpaare geführten Ketten Steinauflagen zu befestigen. Hierbei sind die Ketten zusammen mit ihren Steinauflage-Platten mittels paarweise an einem Rahmen angordneten Umlenkgliedern in Form eines sich horizontal im Bereich des unteren Kettenrad-Lagergestells erstreckenden Kettenspeichers lagerbar. Ferner kann der sich horizontal erstreckende Kettenspeicher auch mit dem Wagen, der die Ausmauerungseinrichtung trägt, verbunden sein.According to the older, unpublished DE patent application P 29 14 651.8, in order to form a vertical stone conveyor path, it has already been proposed to attach stone supports to one or more chains guided around pairs of chain wheels. Here, the chains can be stored together with their stone support plates by means of deflecting links arranged in pairs on a frame in the form of a chain store which extends horizontally in the region of the lower sprocket bearing frame. Furthermore, the horizontally extending one Chain storage can also be connected to the car that carries the brick lining.

Bei der Verwendung von über Kettenradpaaren geführten Endlosketten tritt an Ausmauerungseinrichtungen für metallurgische Gefäße, insbesondere für Stahlwerkskonverter und/oder Hochöfen, der Nachteil großer Steinförderhöhen auf. Ein weiteres Problem derartiger Ausmauerungseinrichtungen entsteht durch die Arbeitsweise an metallurgischen Gefäßen, die Steinreihen von unten nach oben fortschreitend aufeinanderzulegen. Diese Arbeitsweise bedingt ein stufenweises Höherstellen der Arbeitsplattform, was aufgrund der Verwendung von Teleskop-Hubelementen kein Problem bedeutet, was jedoch in bezug auf die vertikale Steinförderstrecke ein bis jetzt ungelöstes Problem darstellt.When using endless chains guided over pairs of sprockets, the disadvantage of large stone delivery heights occurs in lining devices for metallurgical vessels, in particular for steelwork converters and / or blast furnaces. Another problem with such brick lining devices arises from the way they work on metallurgical vessels, in which the rows of stones are successively stacked one on top of the other. This method of operation requires a gradual raising of the work platform, which means no problem due to the use of telescopic lifting elements, but this is a problem that has not yet been solved with regard to the vertical stone conveyor route.

Der Erfindung liegt die Aufgabe zugrunde, aus Ketten gebildete vertikale Steinförderstrecken für Ausmauerungseinrichtungen metallurgischer Gefäße mit selbständig höhenverstellbaren Arbeitsplattformen den laufend wechselnden Höhen anzupassen.The invention has for its object to adjust vertical stone conveyor lines formed from chains for masonry devices of metallurgical vessels with independently height-adjustable work platforms to the constantly changing heights.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß für eine maximale Steinförderhöhe ausgelegte endlose, parallel laufende Kettenpaare im Verlauf ihres ablaufenden Trums über mehrere Paare achsgleicher Kettenräder geführt sind, daß die Kettenradpaare im Mindestabstand ihrer Durchmesser oder weiter entfernt voneinander angeordnet und mit ihren Achsen an einem Rahmen gelagert sind, wobei jeweils zwei benachbarten Kettenradpaaren ein Kettenradpaar mit beweglich in einer Führung gelagerter Achse zugeordnet ist, das im Sinn einer Verminderung oder Vergrößerung der Speicherlänge im Abstand zu den sich benachbarten Kettenradpaaren einstellbar ist und wobei die Steinauflagen jeweils die Kettenraddurchmesser eines Kettenradpaares umgehend außen oder innen an den Ketten befestigt sind. Eine solche Ausbildung weist den Vorteil auf, entsprechend der jeweiligen Hubstellung der Arbeitsplattform die vertikale Länge der vertikalen Steinförderstrecke einrichten zu können, obgleich die Steinauflagen ein Hemmnis für die Anwendung eines Kettenspeichers darstellen.This object is achieved in that endless, parallel chain pairs designed for a maximum stone delivery height are guided over several pairs of axially identical chain wheels in the course of their running run, that the chain wheel pairs are arranged at a minimum distance of their diameter or further apart and with their axes on a frame are stored, with two adjacent sprocket pairs being assigned a sprocket pair with an axle that is movably mounted in a guide, which can be adjusted in the sense of reducing or increasing the storage length in relation to the adjacent sprocket pairs, and wherein the stone supports each immediately the sprocket diameter of a sprocket pair on the outside or are attached to the inside of the chains. Such a design has the advantage of being able to set up the vertical length of the vertical stone conveyor section, depending on the respective lifting position of the work platform, although the stone supports are an obstacle to the use of a chain store.

Die Erfindung ist ausgestaltet, indem die Steinauflagen im wesentlichen zwischen den Kettenrädern eines Kettenradpaares angeordnet sind. Eine solche Raumaufteilung stört insbesondere das Vorhandensein der Steinauflagen im Kettenspeicher nicht.The invention is designed in that the stone supports are arranged essentially between the sprockets of a pair of sprockets. Such a division of space in particular does not disturb the presence of the stone supports in the chain store.

Der Abstand der zugeordneten Kettenräder im Sinn einer Verkürzung oder Verlängerung der nutzbaren Kettenlänge (vertikale Steinförderstrecke) kann dergestalt variiert werden, daß an den beweglich gelagerten Achsen der einstellbaren Kettenräder Zugkörper, wie z. B. Gewichte, Zugfedern oder die Schubstange eines mit seinem Gehäuse erforderlichenfalls gelenkig gelagerten Geradbewegungsantriebs befestigt sind.The distance between the assigned chain wheels in the sense of a shortening or lengthening the usable chain length (vertical stone conveyor path) can be varied in such a way that tensile bodies, such as, for. B. weights, tension springs or the push rod of an articulated linear motion drive, if necessary, are attached with its housing.

Die Speicherfähigkeit des erfindungsgemäßen Kettenspeichers läßt sich außerdem vergrößern. Hierzu wird vorgeschlagen, daß die in einer Reihe nebeneinander angeordneten Kettenradpaare mit ihren Achsen in einer gemeinsamen Führung verschiebbar gelagert sind.The storage capacity of the chain store according to the invention can also be increased. For this purpose, it is proposed that the sprocket pairs arranged in a row next to each other are slidably mounted with their axes in a common guide.

Die Achsen der achsgleichen Kettenradpaare können außerdem geradlinig bewegt werden, wobei nach einer weiteren Verbesserung der Erfindung die gemeinsame Führung aus einer geraden Schienenführung besteht.The axes of the axially identical pairs of sprockets can also be moved in a straight line, the joint guide consisting of a straight rail guide according to a further improvement of the invention.

Die Anordnung des Kettenspeichers innerhalb der Ausmauerungseinrichtung kann entsprechend dem zwischen Hüttenflur und Gefäßöffnung bestehenden Abstand derart vorgenommen sein, daß die den Kettenspeicher bildenden nebeneinander bzw. sich gegenüberliegend angeordneten Kettenräder zusammen mit Kette eine Mäander-Form in horizontaler oder vertikaler Erstreckung bilden.The arrangement of the chain storage within the lining device can be made according to the distance between the hut floor and the vessel opening in such a way that the chain wheels forming the chain storage arranged side by side or opposite one another together with the chain form a meandering shape in a horizontal or vertical extension.

Auf die horizontale Ebene bezogen, weisen die Ausmauerungseinrichtungen allgemein wegen der die Hubplattform tragenden Teleskophubspindeln einen beschränkte Innenfläche auf. Es ist deshalb vorteilhaft, wenn nach einer weiteren Verbesserung der Erfindung die den Kettenspeicher bildenden Kettenräder in einem Raum zwischen sich gegenüberliegenden Teleskophubspindeln für die ringförmige, höhenverstellbare Arbeitsplattform angeordnet sind.In relation to the horizontal plane, the lining devices generally have a limited inner surface because of the telescopic lifting spindles carrying the lifting platform. It is therefore advantageous if, according to a further improvement of the invention, the chain wheels forming the chain store are arranged in a space between opposite telescopic lifting spindles for the annular, height-adjustable working platform.

Weiterhin ist noch vorgesehen, daß sämtliche Kettenräder in einem Rahmen gelagert sind, der vom Rahmender Ausmauerungseinrichtung getrennt ist.Furthermore, it is also provided that all sprockets are mounted in a frame which is separate from the frame of the lining device.

Schließlich wird zusätzlich zu einem separaten Kettenspeicher vorgeschlagen, daß der Rahmen für die Kettenräder aus dem Rahmen der Ausmauerungseinrichtung herausnehmbar ist. Die Erfindung ermöglicht damit einen nachträglichen Einbau an bestehenden und auf mehreren Teleskophubspindeln aufbauenden Ausmauerungseinrichtungen.Finally, in addition to a separate chain store, it is proposed that the frame for the chain wheels can be removed from the frame of the lining device. The invention thus enables retrofitting to existing lining devices that are built on several telescopic lifting spindles.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Es zeigen:

  • Fig. 1 einen senkrechten Schnitt durch die erfindungsgemäße Ausmauerungseinrichtung mit dem auszumauernden Gefäß,
  • Fig. 2 einen horizontalen Schnitt entsprechend der Schnittangabe I - I in Fig. 1,
  • Fig. 3 die Einzelheit der Befestigung der Steinauflagen an den Ketten in vergrößertem Maßstab als Draufsicht,
  • Fig. 4 eine Einzelheit der Stellung der Steinauflagen beim inneren Durchlaufen der Kettenradpaare in vergrößertem Maßstab wie Fig. 3.
An embodiment is shown in the drawing and will be described in more detail below. Show it:
  • 1 shows a vertical section through the lining device according to the invention with the vessel to be lined,
  • 2 shows a horizontal section corresponding to the section information I - I in FIG. 1,
  • 3 shows the detail of the attachment of the stone supports to the chains on an enlarged scale as a top view,
  • 4 shows a detail of the position of the stone supports when passing through the chain wheel pairs on an enlarged scale like FIG. 3.

Die Ausmauerungseinrichtung ist im Einsatz für einen Stahlwerkskonverter 1 gezeichnet (Fig. 1). Die ringförmige Arbeitsplattform 2, deren Arbeitsfläche von dem verkleinerten Durchmesser der Gefäßöffnung la auf den Durchmesser lb mittels nachstellbarer Elemente 2a vergrößert werden kann, wird durch die hydraulisch betätigbaren Teleskophubspindeln 3a, 3b und 3c gestützt. Der Rahmen 4 trägt die Teleskophubspindeln 3a bis 3c und ist selbst mittels Rädern 5 auf Gleisen 6 in Höhe des Hüttenflurs 7 verfahrbar.The lining device is drawn in use for a steelworks converter 1 (FIG. 1). The annular working platform 2, the working surface of which can be increased from the reduced diameter of the vessel opening la to the diameter lb by means of adjustable elements 2a, is supported by the hydraulically actuated telescopic lifting spindles 3a, 3b and 3c. The frame 4 carries the telescopic lifting spindles 3a to 3c and can itself be moved by means of wheels 5 on rails 6 at the level of the hut floor 7.

Die für die Ausmauerung lb benötigten feuerfesten Steine 8 werden über die horizontale Steinförderstrecke 9 auf die vertikale Steinförderstrecke 10 übergeben. Letztere besteht aus einem Kettenpaar 11, dessen einzelne Ketten lla, llb über Kettenradpaare 12a, 12b verlaufen. Die auf das Niveau der Arbeitsplattform 2 geförderten Steine 8 gelangen "über Kopf" auf die Rutsche 13, den Drehtisch 14 und den Rollentisch 15 zur Auflage auf die jeweils unterste Schicht der Ausmauerung Ib.The refractory bricks 8 required for the brick lining 1b are transferred via the horizontal stone conveyor line 9 to the vertical stone conveyor line 10. The latter consists of a pair of chains 11, the individual chains 11a, 11b of which run over pairs of sprockets 12a, 12b. The stones 8 conveyed to the level of the working platform 2 reach "over head" on the slide 13, the turntable 14 and the roller table 15 for resting on the bottom layer of the brickwork 1b.

Die Ketten lla, Ilb werden über die Teleskop-Führungen 16 und 17, die über eine Halterung 16a am Rahmenunterteil 4a befestigt sind, auf die gewünschte vertikale Länge gestreckt. Das ablaufende Trum llc verläuft jeweils über ein Umlenkkettenrad 18 und ein weiteres Umlenkkettenrad 19, die beide am Rahmen 4 mit ihren Achsen drehbar gelagert sind. Weitere Kettenradpaare 20, 21, 22 sind mit ihren Achsen etwa horizontal nebeneinander gelagert. Jeweils zwischen zwei der benachbarten Kettenradpaare 20 bis 22 befinden sich weitere Kettenradpaare 23, 24, 25, deren Achsen in senkrechten Führungen 26, 27 und 28 gleiten. An den Achsen der beweglichen Kettenradpaare 23, 24 und 25 sind Zugkörper 29, 30, 31 befestigt. Letztere könnten ebenso aus am Rahmenunterteil 4a befestigten Zugfedern oder aus Geradbewegungsantrieben bestehen, deren Kolbenstange (hydraulische Kolben-Zylinder-Antriebe vorausgesetzt) entsprechend gesteuert wird.The chains 11a, 11b are stretched to the desired vertical length via the telescopic guides 16 and 17, which are fastened to the lower frame part 4a via a holder 16a. The running strand 11c runs in each case via a deflection sprocket 18 and a further deflection sprocket 19, both of which are rotatably mounted on the frame 4 with their axes. Further sprocket pairs 20, 21, 22 are mounted with their axes approximately horizontally next to each other. Between two of the adjacent sprocket pairs 20 to 22 there are further sprocket pairs 23, 24, 25, the axes of which slide in vertical guides 26, 27 and 28. Tension bodies 29, 30, 31 are fastened to the axes of the movable sprocket pairs 23, 24 and 25. The latter could also consist of tension springs attached to the lower frame part 4a or of linear motion drives whose piston rod (hydraulic piston-cylinder drives provided) is controlled accordingly.

Das ablaufende Trum llc verläuft (Fig. 1) von dem,Umlenkkettenradpaar 19 über die Kettenradpaare 23, 20, 24, 21, 25, 22 und wird dann zum auflaufenden Trum lld.The running run llc runs (FIG. 1) from the deflection sprocket pair 19 over the sprocket pairs 23, 20, 24, 21, 25, 22 and then becomes the running run lld.

An den Kettenpaaren lla, llb sind die Steinauflagen 32 befestigt (Fig. 3). Die Steinauflagen 32 bilden jeweils einen U-förmigen Bügel, der an seinen Ecken mittels Paaren von Winkelstücken 33 an den die Kettenglieder verbindenden Bolzen 34 oder an den Kettengliedern selbst befestigt ist. Für die Befestigung bestehen zwei Möglichkeiten:

  • Die Bügel 32 können entweder zwischen den beiden Rädern 12a eines Kettenradpaares (Fig. 3) an die Kettenbolzen 34 bzw. an die Kettenglieder angeschlossen sein. Die andere Befestigungsart ist außen an den Kettenbolzen 34 bzw. an den äußeren Kettengliedern. Bei beiden Befestigungsarten werden die Durchmesser der Kettenräder für das Ineingriffkommen bzw. für das Außereingriffkommen der Ketten freigehalten bzw. umgangen. Ferner ist zu beachten, daß die Kettenradpaare 12a, 12b, die von den Steinauflagen 32 außen umlaufen werden, einen relativ kleineren Durchmesser aufweisen dürfen. Die Kettenradpaare 18, 20, 21, 22 werden innen umlaufen (Fig. 4) und müssen einen solchen Durchmesser aufweisen, daß die den verschiedenen Steinbreiten entsprechenden Schenkel 32a und 32b der Steinfauflagen 32 die Achse (12c) eines Kettenradpaares nicht berühren. Demnach ergibt sich für die Kettenradpaare 18, 20, 21, 22 ein größerer Durchmesser als für die Kettenradpaare 12a, 12b, 19, 23, 24 und 25.
The stone supports 32 are fastened to the chain pairs 11a, 11b (FIG. 3). The stone supports 32 each form a U-shaped bracket which is fastened at its corners by means of pairs of angle pieces 33 to the bolts 34 connecting the chain links or to the chain links themselves. There are two options for fastening:
  • The bracket 32 can either be connected between the two wheels 12a of a chain wheel pair (FIG. 3) to the chain pins 34 or to the chain links. The other type of fastening is on the outside of the chain pin 34 or on the outer chain links. With both types of fastening, the diameters of the chain wheels are kept free or bypassed for the engagement or for the disengagement of the chains. It should also be noted that the sprocket pairs 12a, 12b, which are surrounded by the stone supports 32 on the outside, may have a relatively smaller diameter. The sprocket pairs 18, 20, 21, 22 are rotated on the inside (FIG. 4) and must have a diameter such that the legs 32a and 32b of the stone supports 32 corresponding to the different stone widths do not touch the axis (12c) of a sprocket pair. This results in a larger diameter for the sprocket pairs 18, 20, 21, 22 than for the sprocket pairs 12a, 12b, 19, 23, 24 and 25.

Das gezeichnete Kettenpaar lla, lIb (Figuren 3 und 4) wird durch den Antriebsmotor 35, der am Rahmenoberteil 4b gelagert ist mittels des Kettenrades 36, des Kettenzuges 36a und des Antriebskettenrades 37, das drehfest auf der Achse des Umlenkkettenrades 18 angeordnet ist, in Bewegung versetzt. Dabei behalten die Steinauflagen 32 ihre Lage in bezug auf die Ketten lla, llb.The drawn chain pair lla, lIb (Figures 3 and 4) is in motion by the drive motor 35, which is mounted on the frame upper part 4b by means of the chain wheel 36, the chain hoist 36a and the drive chain wheel 37, which is arranged in a rotationally fixed manner on the axis of the deflection chain wheel 18 transferred. The stone supports 32 keep their position in relation to the chains 11a, 11b.
