Abstract

An arresting device for preventing a steel making converter which is carried by a trunnion for moving itself during the blowing operation includes a rotatable bearing support for the trunnion or trunnion parts which extend from each side of the bessimer converter which carries a braking disc which is secured to at least one of the trunnion parts. The disc is advantageously mounted so as to be perpendicular to the axis of the trunnion. The trunnion is rotable on bearings carried on bearing supports on each side of the trunnion and a compresser mechanism including two braking jaws engage the disc from respective sides in braking contact therewith.

Description

Die Erfindung betrifft eine Festhaltevorrichtung zur Verhinderung der Eigenbewegung eines in Betrieb befindlichen Konverters.The invention relates to a holding device for preventing the self-movement of a converter in operation.

Beim Konverterbetrieb treten während der Blasperiode durch Reaktionen des Frischmittels mit dem Eisenbad Schwingungen auf, die sich nachteilig auf die Zahnräder des Konverteraufsteckgetriebes auswirken können.During converter operation, vibrations occur during the blowing period due to reactions of the fresh agent with the iron bath, which can have a disadvantageous effect on the gearwheels of the converter slip-on gear.

Man hat daher zur Verhinderung der Übertragung von Bad- . schwingungen des Konverters auf den Konverterantrieb bereits eine Einrichtung geschaffen (DE-AS 25 54 912), mit der bei Aufsteckgetrieben ein Antriebsritzel gegen das Großrad des Stirnradgetriebes verspannbar ist, wobei das Verdrehflankenspiel aufgehoben ist. Dies geschieht mit Hilfe eines zusätzlichen Motors.One therefore has to prevent the transmission of bad. Vibrations of the converter on the converter drive already created a device (DE-AS 25 54 912) with which a drive pinion can be clamped against the large gear of the spur gear in slip-on gearboxes, the backlash being eliminated. This is done with the help of an additional motor.

Bei der bekannten Einrichtung wird nicht gänzlich vermieden, daß die beim Schwingen des Konverters auftretenden Kräfte aus dem Zahntrieb des Getriebes ferngehalten werden. Es bleibt trotz Verspannens eine mechanische Restlose zwischen den Zahnrädern.In the known device, it is not entirely avoided that the forces occurring when the converter vibrates are kept away from the pinion of the transmission. Despite the tension, there remains a mechanical residue between the gears.

Aufgabe der Erfindung ist es daher, eine Festhaltevorrichtung zur Verhinderung der Eigenbewegungen eines in Betrieb befindlichen Konverters zu schaffen, mit der die auftretenden Vibrationen und somit Kräfte vollständig aus dem Aufsteckgetriebe herausgehalten werden.The object of the invention is therefore to provide a holding device for preventing the inherent movements of a converter which is in operation, with which the vibrations and thus forces which occur are kept completely out of the slip-on gear.

Die Lösung dieser Aufgabe geschieht gemäß der Erfindung auf die Weise, wie im kennzeichnenden Teil der Patentansprüche angegeben.This object is achieved according to the invention in the manner as specified in the characterizing part of the claims.

Ein Ausführungsbeispiel der erfindungsgemäßen Festhaltevorrichtung wird nachstehend anhand der schematischen Zeich- nung näher erläutert.An embodiment of the holding device according to the invention is explained in more detail below with reference to the schematic drawing.

Es zeigen:

  • Fig. 1 eine Seitenansicht eines Konverters mit Lagerung und Kippantrieb und
  • Fig. 2 einen Schnitt nach der Linie A - A der Fig. 1.
Show it:
  • Fig. 1 is a side view of a converter with storage and tilt drive and
  • 2 shows a section along the line A - A of FIG. 1st

Das Konvertergefäß 1 ist mit seinem Kippzapfen 2 in Lagern 3 gehalten. Auf dem Kippzapfen ist fliegend das Aufsteckgetriebe 4 mit dem Antriebsmotor 5 aufgesetzt. Der Getriebekasten des Getriebes 4 ist am Fundament 6 über eine Drehmomentstütze 7 abgestützt.The converter vessel 1 is held in its bearings 3 with its pivot pin 2. The slip-on gear 4 with the drive motor 5 is overhung on the tilting pin. The gearbox of the gearbox 4 is supported on the foundation 6 via a torque arm 7.

Auf dem antriebsseitigen Kippzapfen 2 ist eine Bremsscheibe 8 angeordnet, an die zwei andrückbare Bremsbacken 9 einer mit dem Lagerunterbau 10 bzw. dem Fundament 6 verbundenen Andrückvorrichtung 11 angreifen. Das Andrücken der Bremsbacken 9 an die Bremsscheibe 8 kann hydraulisch, pneumatisch oder mechanisch erfolgen (nicht dargestellt).A brake disk 8 is arranged on the drive-side pivot pin 2, to which two pressable brake shoes 9 of a pressing device 11 connected to the bearing base 10 or the foundation 6 engage. The brake shoes 9 can be pressed against the brake disc 8 hydraulically, pneumatically or mechanically (not shown).

Um eine möglichst umfassende Festlegung des Konverters zu erreichen, kann auch auf der der Antriebsseite gegenüberliegenden Seite eine Bremsscheibe 8 auf dem Kippzapfen 2 angeordnet sein, an die ebenfalls eine Andrückvorrichtung 11 mittels Bremsbacken 9 angreift.In order to achieve the most comprehensive possible definition of the converter, a brake disk 8 can also be arranged on the pivot pin 2 on the side opposite the drive side, to which a pressing device 11 also engages by means of brake shoes 9.

Anstelle von kreisrunden Bremscheiben 8 können gegebenenfalls auch Bremsscheiben auf den Kippzapfen des Konverters aufgesetzt werden, die als Kreissegment oder dergleichen ausgeführt sind. In diesem Fall werden an bestimmten Stellen des Umfanges, die mit den gewollten Festhaltepositionen des Konverters übereinstimmen, ausladende Segmentflächenteile von der Andrückvorrichtung 11 erfaßt.Instead of circular brake disks 8, brake disks, which are designed as a circular segment or the like, can optionally also be placed on the pivot pin of the converter. In this case, at certain points on the circumference, which correspond to the intended holding positions of the converter, projecting segment surface parts are gripped by the pressing device 11.
