Description

Die Erfindung betrifft eine Einrichtung zum Ausmauern von metallurgischen Gefäßen, insbesondere von Stahlwerkskonvertern, die einen geschlossenen Boden aufweisen, mit einer an einem Hebezeug befestigten Arbeitsbühne, die in die Arbeitsstellung heb-und senkbar ist und mit einer Transportvorrichtung zum Einbringen der Mauerwerkssteine auf die Arbeitsbühne, ferner mit einer Verteilvorrichtung zum Verteilen der Mauerwerkssteine über den Umfang der Arbeitsbühne und mit einer Übergabevorrichtung zum Übergeben einzelner Mauerwerkssteine von der Arbeitsbühne in ihre Funktionslage.The invention relates to a device for bricking up metallurgical vessels, in particular steelwork converters, which have a closed floor, with a working platform attached to a hoist, which can be raised and lowered into the working position and with a transport device for introducing the masonry stones onto the working platform, further with a distribution device for distributing the masonry stones over the circumference of the working platform and with a transfer device for transferring individual masonry stones from the working platform into their functional position.

Derartige Einrichtungen zum Ausmauern von metallurgischen Gefäßen dienen der Wirtschaftlichkeit der Metallerzeugungsverfahren sowie der Verfahrenstechnik beim Erzeugen von Metallen, insbesondere von Stahl, selbst, um den für die Herstellverfahren erforderlichen Profilverlauf der Ausmauerung sicherzustellen.Such devices for lining metallurgical vessels serve the economy of the metal production process and the process engineering for the production of metals, in particular steel, itself, in order to ensure the profile profile of the lining required for the production processes.

Die eingangs bezeichnete Einrichtung ist aus der DE-OS 28 46 544 bekannt. Obgleich die bekannte Einrichtung Vorteile beim Transportieren der Mauerwerkssteine bietet und obgleich die bekannte Vorrichtung vorteilhaft in ihrer Handhabung ist, erfordert eine derartige Lösung einen erheblichen Anteil an Handarbeit während des Beginns der Ausmauerungsarbeiten. Es hat sich gezeigt, daß insbesondere der Bodenbereich des metallurgischen Gefäßes nur unter Schwierigkeiten zustellbar ist, wobei solche Schwierigkeiten insbesondere dann auftreten, wenn das Gewicht der Mauerwerkssteine durch Vergrößerung ihrer Länge wächst.The device mentioned above is known from DE-OS 28 46 544. Although the known device offers advantages in transporting the masonry stones and although the known device is advantageous in its handling, such a solution requires a considerable amount of manual work during the start of the brickwork. It has been shown that in particular the bottom area of the metallurgical vessel can only be advanced with difficulty, such difficulties occurring in particular when the weight of the masonry stones increases as their length increases.

Der Erfindung ist daher die Aufgabe zugrundgelegt, die Ausmauerungstechnik noch mehr als bisher von manueller Arbeit zu befreien, und zwar insbesondere in solchen Fällen, wenn das Gewicht der Mauerwerkssteine 32 kg und mehr übersteigt, wobei davon ausgegangen wird, daß in solchen Fällen ohnehin Handarbeit für unzulässig erachtet wird.The invention is therefore based on the object, the masonry technology to free more than before from manual work, especially in such cases when the weight of the masonry stones exceeds 32 kg and more, it being assumed that in such cases, manual work for is considered inadmissible.

Die gestellte Aufgabe wird bei der eingangs bezeichneten Einrichtung erfindungsgemäß dadurch gelöst, daß an der Arbeitsbühne zumindest eine obere und zumindest eine untere Übergabevorrichtung angeordnet sind, von denen die untere Übergabevorrichtung zur Zustellung des Gefäßbodens mit Mauerwerkssteinen dient und außerdem demontierbar und entfernbar ist. Die Erfindung vermindert nicht nur insbesondere im Bodenbereich des Gefäßes Handarbeit, sondern ermöglicht auch die Handhabung von Steinen über 720 m Länge, wie z.B. von 1350 mm. Die Erfindung ermöglicht daher, die Zustellung im Bodenbereich für dickere Ausmauerungen als bisher vorzunehmen; ohne die Nachteile der bisherigen Handhabungsweise in Kauf nehmen zu müssen. Ein besonderer Vorteil besteht sodann in dem einfachen Übergang bei der Zustellung des Bodenbereichs in den Wandbereich, bei der die Arbeitsbühne nach Entfernung der unteren Übergabevorrichtung nur noch eine minimale Bauhöhe aufweist und daher bis auf die Bodenausmauerungsschicht herabgesenkt werden kann, um eine äußerst niedrige Zustellungshöhe zwischen der Arbeitsbühne und den Wandbereichen des Gefäßes zu erzielen.The stated object is achieved according to the invention in the device described in the introduction in that at least one upper and at least one lower transfer device are arranged on the work platform, of which the lower transfer device serves to feed the vessel bottom with masonry stones and is also removable and removable. The invention not only reduces manual labor, in particular in the base region of the vessel, but also enables the handling of stones over 720 m in length, such as of 1350 mm. The invention therefore enables the infeed in the floor area to be carried out for thicker brickwork than before; without having to accept the disadvantages of the previous handling. A particular advantage is then the simple transition in the delivery of the floor area into the wall area, in which the working platform has only a minimal overall height after removal of the lower transfer device and can therefore be lowered to the floor lining layer in order to achieve an extremely low delivery height between the Achieve work platform and the wall areas of the vessel.

Nachdem der Bodenbereich des Gefäßes zugestellt worden ist und der daran anschließende Wandbereich in einigen Mauerwerksstein-Schichten erstellt worden ist, kann die Einrichtung nach einem weiteren Merkmal dadurch vereinfacht werden, indem auch die obere Übergabevorrichtung demontierbar und entfernbar ist. Wenn nämlich die Abstandshöhe zwischen der Arbeitsbühne und der tiefsten Zustellungsschicht in höheren Bereichen der Gefäßwandung sehr klein geworden ist, besteht die Möglichkeit, die Mauerwerkssteine in einer horizontalen Ebene unter einer schichtweisen Verstellung der Arbeitsbühne zu verschieben, so daß weitere Hilfsmittel nicht mehr erforderlich sind.After the bottom area of the vessel has been closed and the adjoining wall area has been created in some masonry stone layers, the device can be simplified according to a further feature in that the upper transfer device can also be dismantled and removed. If the distance between the work platform and the deepest infeed layer has become very small in higher areas of the vessel wall, it is possible to move the masonry stones in a horizontal plane with a layer-by-layer adjustment of the work platform, so that additional aids are no longer required.

Nach einem weiteren Merkmal der Erfindung ist vorgesehen, daß die Übergabevorrichtungen jeweils einen horizontalen Schwenkarm mit einem Greiforgan für einen Mauerwerksstein aufweisen. Diese Gestaltung erspart besondere Laufkatzen und senkt daher die Investitionskosten für die Einrichtung.According to a further feature of the invention it is provided that the transfer devices each have a horizontal swivel arm with a gripping member for a masonry stone. This design saves special trolleys and therefore lowers the investment costs for the facility.

Unter diesem Blickwinkel ist die Einrichtung weiterhin dadurch verbessert, daß der Schwenkarm drehbar und an einer Säule gelagert ist und daß die Säule an einem auf dem Arbeitsbühnenrand abgestützten Halterahmen befestigt ist. Diese Lösung sichert eine günstige Verteilung der Stützkräfte, die aus dem Gewicht der Einrichtungsteile selbst bzw. aus dem Gewicht der Mauerwerkssteine herrühren.From this point of view, the device is further improved in that the swivel arm is rotatable and mounted on a column and that the column is attached to a support frame supported on the edge of the work platform. This solution ensures a favorable distribution of the supporting forces which result from the weight of the equipment parts themselves or from the weight of the masonry stones.

In weiterer Verbesserung der Erfindung ist vorgesehen, daß die Säule für die untere Übergabevorrichtung an ihrem unteren Säulenende mit einer drehbaren Lagerplattform versehen ist. Die drehbare Lagerplattform besitzt eine Pufferwirkung, so daß immer zumindest ein oder mehrere Mauerwerkssteine gespeichert werden können, bevor sie ihrer Verlegung zugeführt werden.In a further improvement of the invention it is provided that the column for the lower transfer device is provided at its lower column end with a rotatable storage platform. The rotatable storage platform has a buffering effect, so that at least one or more masonry stones can always be stored before they are moved.

Eine drehbare Arbeitsbühne und damit kleinere zu bewegende Massen werden außerdem dadurch erspart, daß der Halterahmen am Umfang der Arbeitsbühne verfahrbar vorgesehen ist.A rotatable work platform and thus smaller masses to be moved are also saved in that the holding frame is provided so that it can move on the periphery of the work platform.

Hierbei ist die Verfahrbarkeit mit einer günstigen Abstützbarkeit dadurch gekennzeichnet, daß der Halterahmen auf bzw. an Schienen abgestützt ist.The movability with a favorable supportability is characterized in that the holding frame is supported on or on rails.

Die Anbringung solcher Führungsorgane für den Halterahmen wird dadurch vereinfacht, daß Schienen für den Halterahmen auf dem Umfang der Arbeitsbühne und an einem Drehteller der Verteilvorrichtung vorgesehen sind.The attachment of such guide members for the holding frame is simplified in that rails are provided for the holding frame on the circumference of the work platform and on a turntable of the distribution device.

Die Reichweite der Greiforgane wird hinsichtlich der von diesen zu überstreichenden Flächen dadurch vergrößert, daß die Schwenkarme der Übergabevorrichtung aus Gelenkarmen bestehen.The range of the gripping members is increased with regard to the areas to be covered by the fact that the swivel arms of the transfer device consist of articulated arms.

Das Verlegen der Mauerwerkssteine im Boden- bzw. Wandbereich des metallurgischen Gefäßes wird außerdem dadurch erleichtert, daß die Greiforgane an den horizontalen Schwenkarmen entweder aus horizontal- oder aus Vertikalgreiforganen bestehen.The laying of the masonry stones in the floor or wall area of the metallurgical vessel is also facilitated in that the gripping members on the horizontal swivel arms consist of either horizontal or vertical gripping members.

Obere Bereiche des metallurgischen Gefäßes werden zunehmend vereinfacht dadurch zugestellt, indem bei demontierter und entfernter unterer und oberer Übergabevorrichtung auf dem dalterahment ein lösbarer Überbrückungsrollgang vorgesehen ist. Diese Maßnahme gestattet, die Mauerwerkssteine auf der erwähnten horizontalen Ebene ohne großen Kraftaufwand zu bewegen.Upper areas of the metallurgical vessel are increasingly simplified in that a detachable bridging roller table is provided on the old frame when the lower and upper transfer devices are removed and removed. This measure allows the masonry stones to be moved on the horizontal plane mentioned without great effort.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and will be described in more detail below.

Es zeigen:

  • Fig. 1 einen senkrechten Querschnitt durch einen Stahlwerkskonverter während der Zustellung des Gefäßbodens,
  • Fig. 2 denselben Querschnitt durch den Stahlwerkskonverter während des Aufbaus der Zustellung knapp über dem Gefäßboden und
  • Fig. 3 denselben Querschnitt durch den Stahlwerkskonverter während der Zustellung der Wandbereiche.
Show it:
  • 1 is a vertical cross section through a steel mill converter during the infeed of the vessel bottom,
  • Fig. 2 shows the same cross section through the steel mill converter during the construction of the infeed just above the bottom of the vessel and
  • Fig. 3 shows the same cross section through the steel mill converter during the delivery of the wall areas.

Die erfindungsgemäße Einrichtung zum Ausmauern des metallurgischen Gefäßes 1 wird eingesetzt, nachdem der Gefäßboden la verschlossen worden ist, falls ein abnehmbarer Gefäßboden la vorhanden sein sollte. Die Einrichtung wird an dem Hebezeug 2, z.B. an einem Kran, von dem die Hubseile 3 sichtbar sind, durch die Gefäßmündung 4 eingebracht. Das Hebezeug 2 bringt die Arbeitsbühne 5 auch in die erforderlichen Arbeitsstellungen, wobei die Hubseile 3 an einer Traverse 6 angreifen, die mit der Arbeitsbühne 5 starr verbunden ist.The device according to the invention for lining the metallurgical vessel 1 is used after the vessel bottom la has been closed, if a removable vessel bottom la is present should. The device is introduced on the hoist 2, for example on a crane, from which the lifting ropes 3 are visible, through the vessel mouth 4. The lifting device 2 also brings the working platform 5 into the required working positions, the lifting cables 3 engaging on a crossmember 6 which is rigidly connected to the working platform 5.

Die Mauerwerkssteine 7 werden mittels Ketten 8 über eine nicht ausführlich dargestellte, sondern nur angedeutete Transportvorrichtung 9 zugeführt, wobei die Mauerwerkssteine 7 in Trogbehältern 10 bis auf die Arbeitsbühne 5 gelangen. Auf der Arbeitsbühne 5 ist eine Verteilvorrichtung 11 aus einem Förderband 12 und einem Drehteller 13 gebildet. Die Verteilvorrichtung 11 befördert die Mauerwerkssteine 7 in den Bereich des Umfangs 5a an der Arbeitsbühne 5. So gelangt der Mauerwerksstein 7 (Fig. 1) über das Förderband 12 in den Bereich des Umfangs 5a. Von dort wird jeder Mauerwerksstein 7 mittels einer oberen Übergabevorrichtung 14 und/oder einer unteren Übergabevorrichtung 15 in seine jeweilige Funktionslage 16a im Gefäßboden la (Fig. 1) oder 16b im Bereich zwischen Gefäßboden la und Gefäßwandung lb (Fig. 2) oder 16c an der Gefäßwandung 1b (Fig. 3) befördert.The masonry stones 7 are fed by means of chains 8 via a transport device 9, which is not shown in detail, but only indicated, the masonry stones 7 in trough containers 10 reaching the work platform 5. A distribution device 11 comprising a conveyor belt 12 and a turntable 13 is formed on the work platform 5. The distribution device 11 conveys the masonry stones 7 into the area of the circumference 5a on the work platform 5. The masonry stone 7 (FIG. 1) thus reaches the area of the circumference 5a via the conveyor belt 12. From there, each masonry block 7 is moved into its respective functional position 16a in the bottom of the vessel la (FIG. 1) or 16b in the region between the bottom of the vessel la and the wall of the vessel lb (FIG. 2) or 16c by means of an upper transfer device 14 and / or a lower transfer device 15 Vessel wall 1b (Fig. 3) transported.

Gemäß Fig. 1 wandert der Mauerwerksstein 7 in Pfeilrichtung 17 durch die obere Übergabevorrichtung 14 auf die Lagerplattform 18 und von dort mittels der unteren Ubergabevorrichtung 15 in die Funktionsstellung 16a, in der die Mauerwerkssteine 7 wie gezeichnet etwa senkrecht stehen. Eine solche Arbeitsweise ist besonders vorteilhaft für Mauerwerkssteine 7, die Längen von 720 mm, vorzugsweise von 1350 mm aufweisen.1, the masonry stone 7 migrates in the direction of arrow 17 through the upper transfer device 14 onto the storage platform 18 and from there by means of the lower transfer device 15 into the functional position 16a, in which the masonry stones 7 are approximately vertical as shown. Such a method of operation is particularly advantageous for masonry stones 7 which have lengths of 720 mm, preferably of 1350 mm.

Gemäß Fig. 2 ist die untere Übergabevorrichtung 15 demontiert und entfernt, so daß die Arbeitsbühne 5 nunmehr den Raum bis zum fertigen Teil der Zustellung im Gefäßboden la voll ausnutzen kann. Die durch die Transportvorrichtung 9 zugeführten Mauerwerkssteine 7 werden durch das Förderband 12 auf den Drehteller 13 befördert und von dort durch die obere Übergabevorrichtung 14 in die Funktionslage 16b gebracht. Sobald das Niveau der Funktionslage 16b erreicht ist, kann auch auf die Übergabevorrichtung 14, falls dies erwünscht sein sollte, verzichtet werden.2, the lower transfer device 15 is disassembled and removed, so that the working platform 5 can now take full advantage of the space up to the finished part of the infeed in the vessel bottom 1 a. The supplied by the transport device 9 Masonry stones 7 are conveyed by the conveyor belt 12 onto the turntable 13 and from there brought into the functional position 16b by the upper transfer device 14. As soon as the level of the functional position 16b is reached, the transfer device 14 can also be dispensed with, if this should be desired.

Gemäß Fig. 3 ist daher die Übergabevorrichtung 14 demontiert und entfernt. Die Mauerwerkssteine 7 werden nunmehr wie nachstehend noch beschrieben wird, in die Funktionslage 16c gebracht.3, the transfer device 14 is therefore disassembled and removed. The masonry stones 7 are now brought into the functional position 16c, as will be described below.

Für alle auszuführenden Bewegungen sind die Übergabevorrichtungen 14 und 15 mit einem Schwenkarm 19 ausgerüstet, der jeweils ein Greiforgan 20 aufweist. Ein solches Greiforgan 20 kann z.B. aus einem bekannten Elektrozug (z.B. Übergabevorrichtung 14 in Fig.l) oder aus einer Saugnapfvorrichtung (Übergabevorrichtung 15 in Fig.1 bzw. Übergabevorrichtung 14 in Fig. 2) bestehen. Der Schwenkarm 19 ist jeweils drehbar und an einer Säule 21 bzw. 22 gelagert. Die Säule 21 ist der oberen Ubergabevorrichtung 14 und die Säule 22 ist der unteren Übergabevorrichtung 15 zugeordnet. Die Säulen 21 und 22 sind an einem Halterahmen 23 befestigt, der sich auf den Arbeitsbühnenrand 5b aufstützt.For all movements to be carried out, the transfer devices 14 and 15 are equipped with a swivel arm 19, each of which has a gripping member 20. Such a gripping member 20 can e.g. consist of a known electric train (e.g. transfer device 14 in Fig. 1) or a suction cup device (transfer device 15 in Fig. 1 or transfer device 14 in Fig. 2). The swivel arm 19 is rotatable and supported on a column 21 and 22, respectively. The column 21 is assigned to the upper transfer device 14 and the column 22 is assigned to the lower transfer device 15. The columns 21 and 22 are fastened to a holding frame 23 which is supported on the edge 5b of the working platform.

Die untere Säule 22 ist an dem Halterahmen 23 befestigt und weist die drehbare Lagerplattform 18 für eine vorteilhafte Zwischenspeicherung der Mauerwerkssteine 7 auf. Für die Lagerung der unteren Säule 22 sind die Befestigungen 22a und 22b vorgesehen. Die Lagerplattform 18 ist um ihre Längsachse in Pfeilrichtung 24 drehbar.The lower column 22 is fastened to the holding frame 23 and has the rotatable storage platform 18 for an advantageous temporary storage of the masonry stones 7. The fasteners 22a and 22b are provided for the storage of the lower column 22. The bearing platform 18 can be rotated about its longitudinal axis in the direction of the arrow 24.

Die Säulen 21 und 22 gelangen durch den fahrbaren Halterahmen 23 an jede beliebige Stelle des Umfangs 5a. Es ist auch möglich, die Arbeitsbühne 5 selbst gegenüber der Traverse 6 drehbar zu gestalten, indem eine Drehlagerung und ein Antriebsmotor vorgesehen werden, wodurch Maßnahmen für Bewegungen des Halterahmens 23 selbstverständlich überflüssig werden. Bei einer nicht drehbaren Arbeitsbühne 5 sind zur Führung und Abstützung des Halterahmens 23 Schienen 25 auf dem Umfang 5b der Arbeitsbühne 5 bzw. Schienen 26 vorgesehen, die an dem Drehtellerrahmen 13a befestigt sind. Der Drehteller 13 selbst besitzt eine eigene Drehlagerung an dem Drehtellerrahmen 13a. Die notwendigen Radien zum Aufnehmen und Absetzen der Mauerwerkssteine 7 werden durch Gelenkarme 19a und 19b an den Schwenkarmen 19 erzielt. Die Greiforgane 20 sind für vertikal zu stellende Mauerwerkssteine als Vertikalgreiforgane 20b (Fig. 1) ausgeführt, wobei solche Vertikalgreiforgane 20b an Zugmitteln 27 und Schwenkachsen 20c befestigt sind, um die notwendige Bewegungsfreiheit in Pfeilrichtung 17 zu erlangen (Fig. 1). Für die Funktionslage 16b (Fig. 2) sind hingegen Horizontalgreiforgane 20a erforderlich, die ebenfalls an Zugmitteln 27 befestigt sind.The columns 21 and 22 pass through the movable holding frame 23 to any point on the circumference 5a. It is also possible to make the work platform 5 itself rotatable with respect to the crossmember 6 by means of a rotary bearing and a drive motor are provided, whereby measures for movements of the holding frame 23 are of course superfluous. In the case of a non-rotatable work platform 5, rails 25 are provided on the periphery 5b of the work platform 5 or rails 26 for guiding and supporting the holding frame, and are fastened to the turntable frame 13a. The turntable 13 itself has its own rotary bearing on the turntable frame 13a. The necessary radii for receiving and depositing the masonry stones 7 are achieved by articulated arms 19a and 19b on the swivel arms 19. The gripping members 20 are designed for vertical masonry stones as vertical gripping members 20b (FIG. 1), such vertical gripping members 20b being fastened to traction means 27 and pivot axes 20c in order to obtain the necessary freedom of movement in the direction of arrow 17 (FIG. 1). For the functional position 16b (FIG. 2), however, horizontal gripping members 20a are required, which are also attached to traction means 27.

Nach Demontage und Entfernen der unteren und oberen Übergabevorrichtungen 14 bzw. 15 (Fig. 3) wird auf den Halterahmen 23 ein Überbrückungsrollgang 28 befestigt, so daß die Mauerwerkssteine 7 vom Förderband 12 über den Drehteller 13 und den Überbrückungsrollgang 28 in ihre Funktionslage 16c geschoben werden können.After disassembly and removal of the lower and upper transfer devices 14 and 15 (Fig. 3), a bridging roller table 28 is attached to the holding frame 23, so that the masonry stones 7 are pushed from the conveyor belt 12 over the turntable 13 and the bridging roller table 28 into their functional position 16c can.
