Description

Die Erfindung betrifft eine Ausmauerungsvorrichtung für metallurgische Gefäße, insbesondere für Stahlwerkskonverter, mit einer heb- und senkbaren Arbeitsplattform und auf dieser verfahrbaren Steintransportwagen.The invention relates to a lining device for metallurgical vessels, in particular for steelwork converters, with a work platform that can be raised and lowered and a stone transport wagon that can be moved on it.

Derlei Vorrichtungen dienen zum Ausbrechen und Neuzustellen von metallurgischen Gefäßen, deren Feuerfestfutter nach einer gewissen Anzahl von Chargen verschlissen ist. Bei solchen Vorrichtungen werden die Feuerfeststeine entweder von unten oder von oben in das neuzuzustellende metallurgische Gefäß transportiert, vorübergehend auf der Arbeitsplattform gelagert und von dieser aus in ihre vorherbestimmte Lage befördert. Der Arbeitsplattform ist daher stets eine Steintransportvorrichtung zugeordnet, die aus einem Steinaufzug besteht, falls die Steine, deren Gewicht zwischen 36 und 75 kg beträgt, vom Flur des Hüttenwerkes auf die Arbeitsplattform transportiert werden. Für die Zuführung der Steine von oben werden ähnliche Steintransportvorrichtungen eingesetzt. Wegen der zu vermeidenden Totzeiten im metallurgischen Betrieb ist der Transport der Steine von erheblicher Bedeutung, um das metallurgische Gefäß so schnell wie möglich wieder seinem Einsatz zuzuführen.Such devices are used to break out and reposition metallurgical vessels whose refractory lining is worn out after a certain number of batches. In such devices, the refractory bricks are transported either from below or from above into the metallurgical vessel to be newly set up, temporarily stored on the work platform and transported from there to their predetermined position. The work platform is therefore always assigned a stone transport device which consists of a stone elevator if the stones, whose weight is between 36 and 75 kg, are transported from the hall of the iron and steel works to the work platform. Similar stone transport devices are used to feed the stones from above. Because of the dead times to be avoided in the metallurgical operation, the transport of the stones is of considerable importance in order to return the metallurgical vessel to its use as quickly as possible.

Von derartigen Vorrichtungen wird daher gefordert, die Zustellungsarbeit in metallurgischen Gefäßen zu erleichtern, die Zustellungszeiten zu vermindern und die Ausmauerungsleistung zu erhöhen. Diese Bedingungen können 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. Die Arbeiten auf der Arbeitsplattform werden daher durch die Gestaltung, den Aufbau und die Wirkungsweise der verwendeten Vorrichtung erheblich beeinflußt.Such devices are therefore required to facilitate the delivery work in metallurgical vessels, to reduce the delivery times and to increase the lining performance. These conditions can be met by a continuous transport flow of the stones on horizontal and vertical stone conveyor routes. Automation of the stone transport should also save workers or free them up for work on the work platform. The work on the work platform is therefore significantly influenced by the design, structure and mode of operation of the device used.

Es ist bekannt (deutsche Auslegeschrift 12 27 925), bei der Verwendung von Großformat-Steinen den Schwierigkeiten der Vermauerung infolge des großen Gewichtes entgegenzuwirken. Zu diesem Zweck ist es bekannt, auf der heb-und senkbaren Arbeitsplattform eine drehbare Plattform und ein fahrbares und mit einer Hubvorrichtung versehenes Steinsetzgerät anzuordnen.It is known (German Auslegeschrift 12 27 925) to counter the difficulties of masonry due to the large weight when using large format stones. For this purpose, it is known to arrange a rotatable platform and a mobile stone setting device provided with a lifting device on the lifting and lowering working platform.

Es versteht sich von selbst, daß die drehbare Plattform einen Drehantrieb erfordert. Im Hinblick auf die Größe des fahrbaren Steinsetzgerätes mit der Hubvorrichtung kann nur ein einziges derartiges Fahrzeug zu einem gegebenen Zeitpunkt eingesetzt werden. Dadurch entsteht die Schwierigkeit, daß jeweils nur an einer Stelle des auszumauernden Gefäßes gearbeitet werden kann. Diese Arbeitsweise entspricht nicht der eingangs erwähnten Forderung, die Zustellungszeiten zu vermindern und die Ausmauerungsleistung zu erhöhen.It goes without saying that the rotatable platform requires a rotary drive. With regard to the size of the mobile stone setting device with the lifting device, only one such vehicle can be used at a given time. This creates the difficulty that it is only possible to work at one point on the vessel to be bricked up. This way of working does not meet the requirement mentioned at the beginning of reducing delivery times and increasing the brickwork performance.

Der Erfindung liegt die Aufgabe zugrunde, ohne einen größeren Aufwand an angetriebenen Aggregaten eine höhere spezifische Ausmauerungsleistung zu erzielen, d. h. die Zustellungsarbeit in metallurgischen Gefäßen zu verbessern, die Zustellungszeiten zu vermindern und trotz der einfacheren Vorrichtung die Arbeit für das Personal zu erleichtern.The invention has for its object to achieve a higher specific masonry performance without a greater effort on driven units, d. H. improve the delivery work in metallurgical vessels, reduce the delivery times and, despite the simpler device, make work easier for the personnel.

Die gestellte Aufgabe wird bei der eingangs bezeichneten Ausmauerungsvorrichtung dadurch gelöst, daß auf der Arbeitsplattform zu mehreren Umfangsstellen der Ausmauerung Gleise verlaufen, auf denen jeweils ein Steintransportwagen verfahrbar ist, daß jeder Steintransportwagen einen Hubtisch aufweist und daß dem Hubtisch eine im wesentlichen in der jeweiligen Richtung des Gleises liegende, der Ausmauerung zugewandte, einstellbare Steinbrücke zugeordnet ist. Diese Vorrichtung gestattet, an mehreren Stellen der aufzumauernden Zustellung gleichzeitig zu arbeiten. Dadurch wird die spezifische Ausmauerungsleistung erhöht. Bei höherer Ausmauerungsleistung vermindert sich die Zustellungszeit. Die hierfür vorgesehene Vorrichtung ist außerdem einfach, erfordert keine besonders langen Montage- bzw. Demontagezeiten und ist entsprechend einfach zu handhaben. Die körperliche Beanspruchung des Personals hält sich außerdem in Grenzen, weil die Steine aufgrund der Steinbrücke ohne größeren Kraftaufwand bis in ihre Betriebslage geschoben werden können.The stated object is achieved in the bricking device described in the introduction in that tracks run on the work platform to several circumferential locations of the lining, on each of which a stone transport carriage can be moved, that each stone transport carriage has a lifting table and that the lifting table has a substantially in the respective direction of the Track-laying, adjustable stone bridge facing the brickwork is assigned. This device makes it possible to work simultaneously in several places of the delivery to be bricked up. This increases the specific brickwork performance. The delivery time is reduced with higher brickwork performance. The device provided for this purpose is also simple, does not require any particularly long assembly or disassembly times and is accordingly easy to use. The physical strain on the staff is also limited because the stones can be pushed into their operating position without great effort due to the stone bridge.

Eine auch bei kleineren metallurgischen Gefäßen anwendbare Lösung des erfindungsgemäßen Vorschlages besteht darin, daß zumindest zwei Steintransportwagen auf senkrecht zueinander verlaufenden Gleisen auf der Arbeitsplattform vorgesehen sind.A solution of the proposal according to the invention which can also be used in smaller metallurgical vessels consists in that at least two stone transport wagons are provided on the work platform on tracks running perpendicular to one another.

Vorteilhafterweise werden die zwischen den beiden Umfangsstellen der Ausmauerung befindlichen Mittenbereiche durch eine entsprechende Gestaltung der Steinbrücke erfaßt.Advantageously, the central areas located between the two circumferential locations of the lining are covered by a corresponding design of the stone bridge.

Eine andere den praktischen Gegebenheiten entsprechende Gestaltung der Ausmauerungsvorrichtung sieht vor, daß die Gleise für die Steintransportwagen vom Rand eines innerhalb der Arbeitsplattform mündenden Steintransportschachtes radial nach außen geführt sind. Die Steinpakete können daher ohne Schwierigkeiten auch auf den Steintransportwagen abgesetzt werden, ohne daß sich die einzelnen Steintransportwagen gegenseitig behindern. Der erfindungsgemäße Vorschlag berücksichtigt daher auch eine zufälligerweise eintretende Situation, in der mehreren Steintransportwagen gleichzeitig Steinpakete durch die Steintransportvorrichtung zugeführt werden müssen.Another design of the bricking device corresponding to the practical conditions provides that the tracks for the stone transport wagons are guided radially outwards from the edge of a stone transport shaft opening into the working platform. The stone packages can therefore also be placed on the stone transport wagon without difficulty, without the individual stone transport wagons interfering with one another. The proposal according to the invention therefore also takes into account a situation which occurs accidentally, in which stone packages have to be supplied to a plurality of stone transport wagons simultaneously by the stone transport device.

Der Steintransport vom Hüttenflur aus kann ebenfalls erleichtert werden, indem zumindest ein Steintransportwagen mittels des Steinaufzugs auf die Höhe der Gleise hebbar ist.The stone transport from the hut hallway can also be facilitated by at least one stone transport carriage being liftable to the level of the tracks by means of the stone elevator.

Gemäß einem weiteren Merkmal der Erfindung ist vorgesehen, daß der Hubtisch zusammen mit der Steinbrücke am Steintransportwagen drehbar gelagert ist. Die Drehbarkeit des Hubtisches vergrößert den Aktionsbereich des Steintransportwagens bezüglich der zuzustellenden Ausmauerung erheblich.According to a further feature of the invention it is provided that the lifting table is rotatably mounted on the stone transport carriage together with the stone bridge. The rotatability of the lifting table considerably increases the range of action of the stone transport wagon with regard to the lining to be delivered.

Gemäß einer weiteren Ausgestaltungsform der Erfindung ist vorgesehen, daß der Hubtisch mittels Scherenlenkern und zwischen diesen befindlichem Kolben-Zylinder-Antrieb auf einer Drehscheibe des Steintransportwagens angeordnet ist. Diese Antriebsanordnung gestattet, in eingefahrener Lage des Hubtisches ganze Steinpakete aufzuladen und jeweils die oben befindliche Steinreihe in die Höhe der Steinbrücke zu heben. Demzufolge ist vom Bedienungspersonal der Vorrichtung keinerlei Hubarbeit zu leisten.According to a further embodiment of the invention, it is provided that the lifting table is arranged on a turntable of the stone transport carriage by means of scissor links and a piston-cylinder drive located between them. This drive arrangement allows whole stone packages to be loaded in the retracted position of the lifting table and the respective row of stones to be raised to the height of the stone bridge. As a result, no lifting work is to be performed by the operating personnel of the device.

Eine weitere Voraussetzung für die angestrebte erhöhte spezifische Ausmauerungsleistung wird dadurch geschaffen, indem die Ladefläche des Hubtisches in der Größe einer sogenannten Euro-Palette (800 x 1200 mm) ausgelegt ist. Die auf Paletten transportierten Steinpakete können daher unmittelbar von der Steintransportvorrichtung auf den Steintransportwagen mittels einer Kranvorrichtung umgesetzt werden.A further prerequisite for the targeted increased brick lining performance is created by the loading area of the lifting table being designed in the size of a so-called Euro pallet (800 x 1200 mm). The stone packages transported on pallets can therefore be transferred directly from the stone transport device to the stone transport carriage by means of a crane device.

Eine Verbesserung der Erfindung besteht darin, daß die einstellbare Steinbrücke in bezug auf die jeweilige Ausmauerungs-Stirnfläche in ihrer Neigung verstellbar ist. Mit dieser einstellbaren Neigung wird der Höhenunterschied zwischen der wachsenden Ausmauerungshöhe und der eingestellten Höhe der Arbeitsplattform ausgeglichen.An improvement of the invention is that the adjustable stone bridge is adjustable in its inclination with respect to the respective brick face. With this adjustable incline, the height difference between the increasing brick height and the set height of the work platform is compensated.

Schließlich ist vorgesehen, daß die Steinbrücke mittels einem oder mehreren ansetzbaren und wieder lösbaren Brückenteilen in ihrer Länge veränderbar ist. Diese Maßnahme trägt einerseits dazu bei, zwischen zwei Steintransportwagen liegende Bereiche der Ausmauerung zu erreichen und andererseits eine radiale Vergrößerung bzw. Verkürzung des Abstandes zwischen der Arbeitsplattform und der Ausmauerung bei gewölbten Ausmauerungen zu berücksichtigen.Finally, it is provided that the length of the stone bridge can be changed by means of one or more attachable and detachable bridge parts. On the one hand, this measure contributes to reaching areas of the lining between two stone transport wagons and, on the other hand, to take into account a radial enlargement or shortening of the distance between the work platform and the lining in the case of curved linings.

Die erfindungsgemäße Ausmauerungsvorrichtung kann in einem Stahlwerkskonverter mit einem zylindrischen oder birnenförmigen Ausmauerungsprofil, in Hochöfen, Roheisenmischern, Gießpfannen und mit einer Ausmauerung versehenen Unterdruckgefäßen sowie in Sondergefäßen eingesetzt werden.The lining device according to the invention can be used in a steelwork converter with a cylindrical or pear-shaped lining profile, in blast furnaces, pig iron mixers, ladles and vacuum vessels provided with a lining as well as in special vessels.

Die Ausmauerungsvorrichtung weist die Arbeitsplattform 1 mit kreisförmiger Arbeitsfläche la auf, die an weiter nicht dargestellten Hubvorrichtungen befestigt ist, wobei die Hubvorrichtungen die Arbeitsplattform 1 in hängender Konstruktionsweise von oben halten oder stehend von unten stützen. Der nur mit strichpunktierten Linien angedeutete Steinaufzug 2 schließt sich an die Steintransportöffnung 1b in der Arbeitsplattform 1 an.The lining device has the work platform 1 with a circular work surface 1 a, which is fastened to lifting devices (not shown), the lifting devices holding the work platform 1 in a suspended construction from above or supporting standing from below. The stone elevator 2, which is only indicated by dash-dotted lines, adjoins the stone transport opening 1b in the work platform 1.

Gemäß den Figuren 1 und 2 verlaufen auf der Arbeitsfläche la der Arbeitsplattform 1 Gleise 3 und 4, die zu den Umfangsstellen 5, 6, 7 und 8 (Fig. 3) der Ausmauerung 9 hin ausgerichtet sind. Auf den Gleisen sind Steintransportwagen 10, 11 (Fig. 2) bzw. 12 und 13 (Fig. 3) verfahrbar.According to FIGS. 1 and 2, tracks 3 and 4 run on the working surface 1 a of the working platform 1 and are oriented toward the peripheral points 5, 6, 7 and 8 (FIG. 3) of the lining 9. Stone transport carriages 10, 11 (FIG. 2) or 12 and 13 (FIG. 3) can be moved on the tracks.

Die Steintransportwagen 10 bis 13 weisen jeweils einen Hubtisch 14 auf. In den Richtungen 3a bzw. 4a (bzw. in den Gegenrichtungen) ist die Steinbrücke 15 an jedem Steintransportwagen 10 bis 13 vorgesehen.The stone transport wagons 10 to 13 each have a lifting table 14. The stone bridge 15 is provided on each stone transport carriage 10 to 13 in the directions 3a and 4a (or in the opposite directions).

Die gewünschte Leistungssteigerung bei der Herstellung der Ausmauerung 9, die hinter dem Dauerfutter 9a und dem Blechmantel 9b aufzubauen ist, wird im Prinzip schon durch zwei Steintransportwagen 10 und 11 erreicht (Fig. 2), deren Gleise 3 und 4 in aufeinander senkrechten Richtungen 3a, 4a verlaufen. Nach Fertigstellung der Ausmauerung 9 im Bereich der Umfangsstellen 5 und 6 sind die Steinbrücken 15 an der rückwärtigen Seite der Steintransportwagen 10 und 11 zu befestigen, so daß die Steintransportwagen 10 und 11 (ggf. werden durchgehende Gleise 3 und 4 vorausgesetzt) an den Umfangsstellen 7 und 8 eingesetzt werden können. Weitere Lösungsmöglichkeiten werden noch beschrieben.The desired increase in performance in the production of the lining 9, which is to be built up behind the permanent lining 9a and the sheet metal jacket 9b, is in principle achieved by two stone transport wagons 10 and 11 (FIG. 2), the tracks 3 and 4 of which are in mutually perpendicular directions 3a, 4a run. After completion of the brick lining 9 in the area of the circumferential points 5 and 6, the stone bridges 15 are to be fastened on the rear side of the stone transport wagons 10 and 11, so that the stone transport wagons 10 and 11 (continuous tracks 3 and 4 may be required) at the circumferential points 7 and 8 can be used. Further possible solutions are described.

Sofern die Gleise 3 und 4 von der Steintransportöffnung 1b aus verlaufen und auch kein Kran für das Umsetzen von der einen Umfangsstelle auf eine gegenüberliegende eingesetzt werden soll, weist jeder Steintransportwagen 10 bis 13 eine Drehscheibe 16 auf. Der Hubtisch 14 lagert mittels Scherenlenkern 17a, 17b auf der Drehscheibe 16 und wird mittels eines schräg eingebauten Kolben-Zylinder-Antriebs 18 gehoben oder gesenkt. Die Ladefläche 19 des Hubtisches 14 weist die Größe einer sogenannten Euro-Palette auf, d. h. eine Ladefläche von 800 x 1200 mm, so daß unzerlegte Euro-Paletten 20 mit kompakten Steinpaketen 21 verarbeitet werden können.If the tracks 3 and 4 run from the stone transport opening 1b and no crane is to be used for moving from one circumferential point to an opposite one, each stone transport carriage 10 to 13 has a turntable 16. The lifting table 14 is mounted on the turntable 16 by means of scissor links 17a, 17b and is raised or lowered by means of an obliquely installed piston-cylinder drive 18. The loading area 19 of the lifting table 14 has the size of a so-called euro pallet, i. H. a loading area of 800 x 1200 mm, so that unassembled Euro pallets 20 can be processed with compact stone packages 21.

Die Steinbrücke 15 ist an dem Rahmenteil 22 über das Schwenkgelenk 23 befestigt und mittels der Kniehebel 24a, 24b in der Neigung einstellbar und feststellbar. Die Steinbrücke 15 ist außerdem vorteilhafterweise in der Form einer Zunge ausgebildet, wodurch das Ablegen der schweren Steine 9d auf der Ausmauerungs-Stirnfläche 9c erleichtert wird. Der Rahmenteil 22 kann außerdem demontierbar vorgesehen sein und an die rückwärtige Seite wieder angesetzt werden (nicht dargestellt).The stone bridge 15 is fastened to the frame part 22 via the swivel joint 23 and the inclination can be adjusted and ascertained by means of the toggle levers 24a, 24b. The stone bridge 15 is also advantageously designed in the form of a tongue, which makes it easier to place the heavy stones 9d on the brick face 9c. The frame part 22 can also be provided such that it can be removed and reattached to the rear side (not shown).

Die Verwendung der Drehscheibe 16 gestattet demgegenüber eine Schwenkung des Brückenteils 15 auf dem Kreisbogen 25, woraus sich die Reichweite des Brückenteils 15 ergibt. In Fig. 2 sind diese Endstellungen strichpunktiert angedeutet und mit 26 bzw. 27 bezeichnet, und in Fig. 3 erscheinen diese Endstellungen durch die strichpunktierten Umrisse der Steintransportwagen und sind nach links geschwenkt mit 27 und nach rechts geschwenkt mit 28 bezeichnet.In contrast, the use of the turntable 16 allows the bridge part 15 to be pivoted on the circular arc 25, which results in the range of the bridge part 15. In Fig. 2, these end positions are indicated by dash-dotted lines and designated 26 and 27, and in Fig. 3 these end positions appear through the dash-dotted outline of the stone transport car and are pivoted to the left with 27 and pivoted to the right with 28.

Aus diesen Endstellungen 26, 27 (Fig. 2) bzw. 27, 28 (Fig. 3) ergibt sich, daß die relativ schweren, von Hand zu bewegenden Steine 21a nur kurze Wege zu bewegen sind.From these end positions 26, 27 (FIG. 2) and 27, 28 (FIG. 3) it follows that the relatively heavy stones 21a that can be moved by hand can only be moved within short distances.

Aus Fig. 1 ergibt sich ferner, daß die Steintransportwagen 10 bis 13 bei abgeklappter Steinbrücke 15 (strichpunktiert gezeichnet) durch die Steintransportöffnung 1b mittels des Steinaufzugs 2 gehoben oder abgesenkt werden können. Das Beladen der Steintransportwagen 10 bis 13 kann daher vorteilhafterweise schon auf dem Hüttenflur erfolgen, so daß die Steintransportwagen auf dem Hüttenflur in den Steinaufzug 2 gefahren, danach gehoben und auf der Arbeitsfläche la zu den Umfangsstellen 5 bis 8 verbracht werden. In dieser Höhenlage wird die Steinbrücke 15 wieder in ihre Arbeitslage hochgeklappt.1 also shows that the stone transport carriages 10 to 13 can be raised or lowered through the stone transport opening 1b by means of the stone elevator 2 when the stone bridge 15 is folded down (shown in broken lines). The loading of the stone transport wagons 10 to 13 can therefore advantageously already take place in the hut hallway, so that the stone transport wagons are moved into the stone elevator 2 in the hut hallway, then lifted and brought to the peripheral points 5 to 8 on the working surface la. At this altitude, the stone bridge 15 is folded back into its working position.
