Description

Schienengebundene Transporteinrichtung für schwerste Lasten Rail-bound transport equipment for the heaviest loads
Beschreibungdescription
Die Erfindung betrifft eine schienengebundene Transporteinrichtung für schwerste Lasten, insbesondere zum Wechseln von Stahlwerkskonvertern mit einem Fahrzeug, welches die Last selbständig übernimmt und auf dem Weg zur Abgabestation über Schienen geführt wird, deren Transportrichtung an einer Wendestation insbesondere um 90° geändert ist.The invention relates to a rail-bound transport device for heaviest loads, in particular for changing steelworks converters with a vehicle, which takes over the load independently and is guided on the way to the delivery station via rails, the transport direction of which is changed in particular by 90 ° at a turning station.
Aus DE-AS 24 04 868 ist ein Transportwagen bekannt, auf dem ein längliches im wesentlichen zylindrisches Gefäß gelagert ist, und bei dem seitlich am Gefäß angeordnete Antriebe mit den am Gefäßmantel vorgesehenen Angriffsmitteln eine beim Abheben des Gefäßes von den Drehgestellen ungetrennt bleibende Baueinheit bildet.From DE-AS 24 04 868 a trolley is known, on which an elongated, essentially cylindrical vessel is mounted, and in the case of which drives arranged on the side of the vessel with the attack means provided on the vessel jacket forms a structural unit that remains inseparable when the vessel is lifted off the bogies.
Die Drehachse dieses als Roheisenmischer ausgebildeten Gefäßes ist parallel zur Hauptachse des Transportwagens.The axis of rotation of this vessel, which is designed as a pig iron mixer, is parallel to the main axis of the transport carriage.
Auf der Konferenz „21 st. Century Steel Industry of Russia and CIS" vom 06.06. bis 10.06.1994 in Moskau wurde ein Konverterwechselsystem vorgestellt. Hieraus ist ein Konverterwechselfahrzeug (im wesentlichen Beispiel 2.3 und Figur 13) bekannt, bei dem der Konverter auf einer im Fahrgestell drehbar gelagerten Platte deponierbar ist.At the conference “21 st. Century Steel Industry of Russia and CIS "from June 6th to June 10th, 1994 in Moscow a converter change system was presented. From this a converter change vehicle (essentially example 2.3 and figure 13) is known in which the converter can be deposited on a plate rotatably mounted in the chassis .
Unterhalb dieser Platte sind Kolben-Zylinder-Einheiten vorgesehen, die an einer vorgegebenen Wegstrecke des Fahrzeugs ausgefahren werden und die Möglichkeit eröffnen, das Fahrgestell in seiner Richtung zu verdrehen und die Räder nach dem Drehen auf dem gewünschten Schienenstrang abzusetzen. Der Nachteil dieses Konverterwechselfahrzeugs ist nicht nur der konstruktiv relativ komplizierte und wartungsintensive Drehkranz, sondern auch die gesamte Bauhöhe des Fahrzeugs.Below this plate, piston-cylinder units are provided, which are extended along a predetermined distance of the vehicle and open up the possibility of rotating the chassis in its direction and placing the wheels on the desired rail track after the rotation. The disadvantage of this converter change vehicle is not only the relatively complicated and maintenance-intensive turntable, but also the overall height of the vehicle.
Die Erfindung hat sich daher das Ziel gesetzt, mit konstruktiv einfachen Mitteln eineThe invention has therefore set itself the goal of using a structurally simple means
Transporteinrichtung für schwerste Lasten, insbesondere für einen Stahlwerkskonverter zu schaffen, die eine möglichst geringe lichte Höhe auf seinem Transportweg erforderlich macht.To create a transport device for the heaviest loads, in particular for a steelworks converter, which requires the lowest possible clear height on its transport route.
Die Erfindung erreicht dieses Ziel durch den Verfahrensanspruch 1 und denThe invention achieves this goal by method claim 1 and
Vorrichtungsanspruch 3. Die übrigen Ansprüche bilden vorteilhafte Weiterbildungen der Erfindung.Device claim 3. The remaining claims form advantageous developments of the invention.
Erfindungsgemäß wird die Last nach seiner Übernahme von der schienengebundenen Transporteinrichtung so tief wie möglich im Fahrzeugrahmen abgesenkt. Durch die konstruktive Vorgabe der Hallen sind Wendepunkte zwischen der Aufnahmestation und der Abgabestation erforderlich. In diesen Wendepunkten wird erfindungsgemäß die Last auf nahezu identischem Niveau gehalten und die Kraftübertragung von Transporträdern, die mit den geraden Schienensträngen korrespondieren, übertragen auf Drehräder, die mit einer im Kreis geführten Schiene korrespondieren. In dieser Wendestation wird die gesamte Transporteinrichtung gewendet und nach Erreichen der neuen Fahrtrichtung wieder auf dem Schienenstrang auf den Transporträdern abgesetzt.According to the invention, the load is lowered as deep as possible in the vehicle frame after being taken over by the rail-bound transport device. Due to the design of the halls, turning points between the reception station and the delivery station are required. At these turning points, according to the invention, the load is kept at an almost identical level and the power transmission from transport wheels, which correspond to the straight rail tracks, is transferred to rotary wheels, which correspond to a rail guided in a circle. In this turning station, the entire transport device is turned and, once the new direction of travel has been reached, set down again on the rail track on the transport wheels.
Die Kreuzungspunkte der Schienen sind dabei so ausgestaltet, daß ein Wechsel der Kraftübernahme von der Radlauffläche mit der Schienenlauffläche auf die Spurkränze und den Schienenfuß erfolgt.The crossing points of the rails are designed in such a way that the power take-over changes from the wheel tread with the rail tread to the wheel flanges and the rail foot.
Durch das tiefstmögliche Absenken der Last in den Fahrzeugrahmen der Transporteinrichtung wird es möglich, Hindernisse wie Kranbahnträger oder Bühnen zu unterfahren, wobei . :s tiefste Maß aus der Addition der Gefäßhohe plus erforderliche Freimaße zwischen Konverterboden und Hüttenflur besteht.The lowest possible lowering of the load in the vehicle frame of the transport device makes it possible to pass under obstacles such as crane runway girders or platforms. : s lowest dimension consists of the addition of the vessel height plus the required clearance between the converter floor and the hut floor.
In vorteilhaften Ausgestaltungen werden jeweils zwei Räder zu einer Radeinheit zusammengefaßt, die dabei an Schwingen angeordnet sind. An jeweils einem Ende jeder Schwinge ist eine VerStelleinrichtung zur Einstellung der erforderlichen Höhe relativ zum Fahrgestell angeordnet. Zum gleichmäßigen Verteilen der Kraft sind zwischen den Verstellelementen und den Schwingen Kraftausgleichselemente, im wesentlichen Federn, angeordnet.In advantageous embodiments, two wheels are combined to form a wheel unit, which are arranged on rockers. At one end each each rocker is an adjusting device for adjusting the required height relative to the chassis. To evenly distribute the force, force compensation elements, essentially springs, are arranged between the adjusting elements and the rockers.
In einer vorteilhaften Ausgestaltung der Transporträder zum Fahrzeugrahmen sind an den einander zugeneigten Enden der Schwingen Spindeln vorgesehen, die über eine Wippe mit dem Fahrzeugrahmen verbunden sind.In an advantageous embodiment of the transport wheels to the vehicle frame, spindles are provided at the inclined ends of the rockers, which are connected to the vehicle frame via a rocker.
Zum exakten Aufnehmen der hier vorliegenden hohen Kräfte und exakten Zentrierung ist in einer Ausgestaltung die Schienenauflagefläche des kreisförmig geführten Schienenstranges proportional zum Radius zum Kreismittelpunkt hin geneigt.In one embodiment, the rail support surface of the circularly guided rail track is inclined proportionally to the radius toward the center of the circle in order to absorb the high forces present here and exact centering.
Zur Vermeidung von Unterbrechungen der Kraftaufnahme sind an den Kreuzungspunkten der Schienenfuß und die Schienenauflagefläche in der Weise ausgestaltet, daß Teile der Schienen keilförmig abfallend und an den entsprechenden Positionen der Schienenfuß keilförmig ansteigend ausgestaltet ist.To avoid interruptions in the force absorption, the rail base and the rail support surface are designed at the intersection points in such a way that parts of the rails are wedge-shaped and wedge-shaped at the corresponding positions.
Durch die konstante Aufnahme der Kraft wird es möglich, die Last, hier im wesentlichen ein Stahlwerkskonverter, stets in gleicher horizontaler Lage und damit auf dem tiefsten Punkt in einer Stahlwerkshalle zu halten. Auf diese Weise werden kostenträchtige konstruktive Aufwendungen, insbesondere bezüglich der Kranbahnhöhen und/oder der Schienenlage vermieden.The constant absorption of the force makes it possible to keep the load, essentially a steelworks converter, always in the same horizontal position and thus at the lowest point in a steelworks hall. In this way, costly design efforts, in particular with regard to the crane runway heights and / or the rail position, are avoided.
