Description

Hubbalkenherd, dessen durch Querträger miteinander verbundene und in waagerechter Richtung verschiebbare Hubbalken an Pendelstangen aufgehängt sind Zum Heben und Senken des beweglichen Baüsensystems von Hubbalkenöfen sind Vorrichtungen bekannt, bei denen das System, entweder auf Rollen gelagert oder an Pendeln aufgehängt, durch zweiarmige Hebelgehalten wird, die Gegengewichte für den Gewichtsausgleich des Balkensystems tragen. Auf den Wellen dieser Hebel sitzen Betätigungshebel, an denen das Äntriebsgestänge angelenkt ist; durch dessen 1-Iinundherbewegung die Hub-und Senkbewegung des .Balkensystems zustande kommt. Die Gegengewichte bedeuten nicht nur einen Mehraufwand an Werkstoff, . sondern erfordern auch eine beträchtliche Erhöhung der da bei jedem Hub die hin und her gehenden Massen beschleunigt und verzögert werden müssen. Dieser Mehraufwand wird besonders bei langen öfen mit Balken aus Schamottesteinen so groß; daß ihre Ausführung oft in Frage gestellt ist.Walking beam hearth, its interconnected by cross members and horizontally displaceable lifting beams are suspended from pendulum rods There are devices for raising and lowering the movable structure of walking beam ovens known where the system, either mounted on rollers or suspended from pendulums, is held by two-armed levers, the counterweights for counterbalancing of the beam system. Actuating levers sit on the shafts of these levers which the drive linkage is articulated; by its 1-iinunderschbewegung the stroke and Lowering movement of the bar system comes about. The counterweights don't mean only an additional cost of material,. but also require a considerable amount Increase in the masses moving back and forth accelerated and decelerated with each stroke Need to become. This extra effort is particularly evident in long ovens with beams Fireclay bricks so big; that their execution is often questioned.

Es sind auch Schwingb,alkenherde bekannt, bei denen das `Balkensystem an den freien Enden von Pendeln fest angelenkt ist und bei denen die Pendelhewegungen sowohl für den Heb- und Senkvorgang als auch für den Vorschub ausgenutzt wird. Hierbei muß jedoch das zweite Balkensystem, auf dem das Glühgut nach Beendigung einer Schwingung abgesetzt wird, gleichfalls heb- und senkbar aus= gestaltet sein. , Dadurch werden aber zusätzliche Bewegungseinrichtungen und zusätzliche Antriebskräfte erforderlich.Schwingb, alken stoves are also known in which the `` beam system is firmly hinged at the free ends of pendulums and where the Pendelhewegungen is used both for the lifting and lowering process as well as for the feed. Here However, the second bar system must be used, on which the material to be annealed after the end of an oscillation is deposited, can also be raised and lowered from = be designed. , This will be but additional movement devices and additional drive forces are required.

Die vorliegende Erfindung vermeidet alle Nachteile der bekannten Einrichtungen dadurch, daß die Aufhängung des beweglichen Balkensystems ohne Gegengewichte erfolgt und trotzdem die Beanspruchung der Gestänge und die erforderliche Antriebskraft in normalen Grenzen bleiben. Zu diesem Zweck wird das Balkensystem an Pendeln aufgehängt, die um feste Drehpunkte schwingen. In der tiefsten Stellung des Hubbalkensystems stehen die Pendel senkrecht. An ihrem unteren Ende tragen sie Rollen, auf denen die Tragrahmen für die Hubbalken längs verschieblich aufliegen. Die Pendel sind untereinander durch ein Gestänge verbunden, das durch eine Antriebskraft hin und her bewegt wird. Soll das Balkensystem gehoben werden, so werden die Pendel aus ihrer senkrechten Lage gezogen, bis die erforderliche Hubhöhe erreicht ist, wobei die das Hubbalkensystem tragenden Rollen unter dem Tragrahmen entlang gleiten, die Hubbalken in ihrer Längsrichtung also nicht verschoben werden. Der Ausschlagwinkel der Pendel wird dabei zweckmäßig so gewählt, daß die das Gestänge bewegende Kraft nur einen Bruchteil des Systemgewichts zu überwinden hat.The present invention avoids all of the disadvantages of the known devices in that the suspension of the movable beam system takes place without counterweights and nevertheless the stress on the linkage and the required driving force in normal The limits remain. For this purpose, the beam system is suspended from pendulums that swing around fixed pivot points. Stand in the lowest position of the walking beam system the pendulums perpendicular. At their lower end they carry roles on which the support frame for the lifting beam to slide lengthways. The pendulums are through each other connected a linkage that is moved back and forth by a driving force. Intended to If the beam system is raised, the pendulums are lifted from their vertical position pulled until the required lifting height is reached, using the walking beam system slide along supporting rollers under the support frame, the walking beams in their longitudinal direction so not be postponed. The angle of deflection of the pendulum becomes appropriate chosen so that the force moving the linkage is only a fraction of the system weight has to overcome.

Die Rollen, auf denen die Tragbalken des beweglichen Balkenherdes ruhen, ermöglichen dabei, daß die waagerechte Bewegung des Systems in bekannter Weise unabhängig von der mit Hilfe der Pendel erzielten Auftmdabbewegung ausgeführt werden kann.The rollers on which the supporting beams of the moving beam hearth rest, thereby allowing the horizontal movement of the system in known Way independently of the Auftmdabbewegung achieved with the help of the pendulum can be.

Die Zeichnung zeigt eine beispielsweise Ausführungsform des Gegenstandes der Erfindung, und zwar in Abb. i einen senkrechten Längsschnitt durch einen Teil des Tragrahmens mit einem der Aufhängungspendel, in Abb. a einen Querschnitt durch den Ofen. Auf dem Rahmen i sind mittels der Querträger z und der Stützen 3 die beweglichen Hubbalken 4, gelagert. Sie bewegen sich in Längsschlitzen des festen Herdes 5. Die Rahmenträger i sind, zweckmäßig unter Zwischenschaltung fest mit ihnen verbundener Rollbahnen 6, auf Rollen 7 gelagert, die ihrerseits an den schwingenden Enden der Pendel 8 befestigt sind. Diese sind in ihren Drehpunkten 9 fest, z. B. am Ofengestell, aufgehängt. In den Punkten io greifen die Zugstangen i i an, die vom Getriebe aus hin und her bewegt werden. Die Lage der Punkte io kann beliebig gewählt werden, gegebenenfalls auch mit- den Achsen der Rollen 7 zusammenfallen.The drawing shows an exemplary embodiment of the subject matter of the invention, namely in Fig. I a vertical longitudinal section through part of the support frame with one of the suspension pendulums, in Fig. A a cross section through the furnace. The movable lifting beams 4 are mounted on the frame i by means of the cross members z and the supports 3. They move in longitudinal slots of the fixed hearth 5. The frame girders i are mounted on rollers 7, which are in turn attached to the swinging ends of the pendulums 8, expediently with the interposition of roller tracks 6 permanently connected to them. These are fixed in their pivot points 9 , for. B. on the oven rack. The tie rods ii, which are moved back and forth by the gearbox, attack points io. The position of the points io can be selected as desired, and the axes of the rollers 7 may also coincide.

Die Betätigung der Vorrichtung geschieht wie folgt: Das in seiner Längsrichtung festgehaltene Hubbalkensystem ¢ wird durch Ausschwingen der Pendel 8 so weit angehoben, bis die Hubbalken über die Oberfläche des Herdes 5 hervorragen und dabei das Glühgut von der Herdfläche abheben. Dabei gleiten die Rollen 7 unter der Rollbahn 6 entlang. Darauf wird das Balkensystem 4 um das gewünschte Maß in Längsrichtung verschoben und festgelialten, worauf die Hebel8 in ihre setikrechte Lage zurückgelassen werden. Dadurch wird das Balkensystem wieder unter die Herdfläche 5 lotrecht abgesenkt. Jetzt wird das bewegliche Balkensystem in seine Ausgangsstellung zurückgeholt, worauf ein neuer Bewegungsvorgang beginnen kann.The operation of the device happens as follows: That in his The walking beam system ¢ is held in the longitudinal direction by swinging the pendulum 8 raised until the lifting beams protrude above the surface of the cooker 5 and at the same time lift the material to be annealed from the stove surface. The rollers 7 slide under the runway 6 along. The beam system 4 is then moved to the desired extent in Shifted longitudinally and festgelialten, whereupon the lever8 in their setikrechte Location to be left behind. This will bring the bar system back under the stove top 5 lowered vertically. Now the movable beam system is in its starting position fetched back, whereupon a new movement process can begin.
