Description

Die Erfindung betrifft eine Hebevorrichtung für schwere Lasten von länglicher Form, insbesondere mehrachsige Roheisentransportwagen, sogenannte Torpedowagen.The invention relates to a lifting device for heavy loads of elongated shape, in particular multi-axis pig iron transport wagons, so-called torpedo wagons.

Torpedowagen dienen zum Transport von flüssigem Roheisen von Hochofenanlagen zu Stahlwerken. Sie haben üblicherweise 12 bis 16 Achsen, eine Länge von 20 bis 30 Meter und ihr Leergewicht schwankt in Abhängigkeit von der Ausführung zwischen 150 und 300 Tonnen. Die Lagerschemel des Behälters stützen sich beidseitig auf 2 bis 4 Drehgestelle, welche je mit 2 Radachsen ausgerüstet sind und müssen nach Ablauf von festgesetzten Betriebszeiten überholt werden. Hierzu werden die Enden des Torpedokörpers von den Schemeln gelöst und abgehoben. Während der Wartung der Fahrschemel (einige Tage) kühlt das Torpedogefäss ab, so dass dieses eventuell mit einer neuen Ausmauerung versehen werden kann.Torpedo cars are used to transport molten pig iron from blast furnace systems to steelworks. They usually have 12 to 16 axles, a length of 20 to 30 meters and their unladen weight varies between 150 and 300 tons depending on the version. The storage bolsters of the container are supported on both sides by 2 to 4 bogies, which are each equipped with 2 wheel axles and must be overhauled after fixed operating times. For this purpose, the ends of the torpedo body are detached from the stools and lifted off. During the maintenance of the subframe (a few days), the torpedo tube cools down so that it can possibly be given a new lining.

Bisher wurden kleine Torpedos (etwa 160 Tonnen) mit Hilfe eines schweren Walzwerk-Baukranes von den Fahrschemeln abgehoben. Dabei wurden nacheinander die Enden des Torpedokörpers leicht angehoben und anschliessend auf Stützen abgesetzt. Die Stahltrossen des Kranes wurden an speziellen am Torpedokörperende vorgesehenen Griffen befestigt und mussten gegen hohe Temperatureinflüsse geschützt werden. Dieses Verfahren war wegen des hohen Gewichts und der hohen Temperatur (ungefähr 200°C) des Torpedokörpers zeitraubend und aufwendig. Ausserdem versperrte der Kran die ganze Halle. Grosse Torpedos (über 200 Tonnen} mussten mit Hilfe von druckölbetriebenen Hubelementen und speziell für diese Anwendung gebauten Portal-Montageböcken angehoben und nach Lösung vom Lagerschemel auf Stützen abgelassen werden. Auch hier wurde ein Torpedoende nach dem andern vom Fahrschemel gelöst.So far, small torpedoes (around 160 tons) have been lifted off the subframes with the help of a heavy rolling mill construction crane. The ends of the torpedo body were raised slightly one after the other and then placed on supports. The steel cables of the crane were attached to special handles provided on the end of the torpedo body and had to be protected against high temperature influences. This procedure was time-consuming and complex because of the high weight and the high temperature (approximately 200 ° C.) of the torpedo body. The crane also blocked the entire hall. Large torpedoes (over 200 tons) had to be lifted with the help of pressure oil-operated lifting elements and portal mounting frames specially built for this application, and then had to be released from the support stool on supports. Here, too, one end of the torpedo was released from the subframe.

Diese Vorgänge sind nicht nur mühsam, sondern auch gefährlich. Beim Anheben eines Torpedoendes gelangt dieses in eine schräge Lage und- droht wegzugleiten, da zu diesem Zeitpunkt das andere Torpedoende nicht mehr an dem zweiten, festgesetzten Lagerschemel starr befestigt sein darf oder falls das andere Torpedoende schon auf Stützen ruht, dieser nur mühsam Längskräften von dieser Grössenordnung standhalten kann.These processes are not only tedious but also dangerous. When one end of the torpedo is lifted, it ends up in an inclined position and threatens to slide away, because at this point the other end of the torpedo may no longer be rigidly attached to the second, fixed stool or if the other end of the torpedo is already resting on supports, this is only laboriously subjected to longitudinal forces Order of magnitude can withstand.

Aus der DE-A-2 251 609 ist ein verschiebbarer Prüfstand für Kraftfahrzeuge bekannt, der mit Hilfe einer Hebebühne anhebbar ist. Der Prüfstand umfasst zwei Längsträger welche über Querträger starr miteinander verbunden sind. Unterhalb der Längsträger sind Stützen sowie Laufräder angeordnet, wobei letztere zum Tragen gelangen, wenn die Stützen teilweise entfernt sind.From DE-A-2 251 609 a sliding test bench for motor vehicles is known which can be raised with the aid of a lifting platform. The test bench comprises two side members which are rigidly connected to one another via cross members. Supports and running wheels are arranged below the longitudinal beams, the latter coming into effect when the supports are partially removed.

Aufgabe der Erfindung ist es, eine Hebevorrichtung vorzuschlagen, welche die obigen Nachteile vermeidet, sich den Neigungen der Last beim Anheben anpasst und ein Absetzen der Last in der gewünschten Lage erlaubt.The object of the invention is to propose a lifting device which avoids the above disadvantages, adapts to the inclinations of the load when lifting and allows the load to be set down in the desired position.

Diese Aufgabe wird durch die in Anspruch 1 gekennzeichnete Erfindung gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unter-. ansprüchen wiedergegeben.This object is achieved by the invention characterized in claim 1. Advantageous embodiments of the invention are in the subs. claims reproduced.

Die Vorteile der Vorrichtung bestehen darin, dass man den Anhebe- und Absetzvorgang genau steuern und aus sicherer Entfernung beobachten kann. Der Torpedokörper bleibt immer in horizontaler Lage, so dass nun auch in Notfällen Reparaturarbeiten bei gefülltem Torpedo möglich sind. Er gerät auch nicht in eine oszillierende Bewegung, wie dies bei an Kranen befestigtem Gut üblich ist ; es ist besonders zeitsparend, dass der Torpedokörper bei der Lösungs- und Befestigungsarbeit an die Fahrschemel millimetergenau bewegt werden kann. Dank der neuen Vorrichtung brauchen die Torpedokörper nicht mehr mit speziellen Halterungen zum Anheben versehen werden.The advantages of the device are that the lifting and lowering process can be precisely controlled and observed from a safe distance. The torpedo body always remains in a horizontal position, so that repair work with a full torpedo is now possible even in emergencies. It also does not get into an oscillating movement, as is customary with goods attached to cranes; it is particularly time-saving that the torpedo body can be moved with millimeter precision when loosening and fixing the subframe. Thanks to the new device, the torpedo bodies no longer need to be provided with special brackets for lifting.

Von besonderem Wert in der Entwicklung der Vorrichtung war die Erkenntnis der Anmelderin, dass, entgegen der vorherrschenden Meinung der Fachwelt, nicht nur ein Anheben und Lagern der Torpedos in unmittelbarer Nähe der Stellen, wo sie an den Fahrschemein befestigt sind, durchführbar ist, sondern dass man diese auch mittels gewichtsverteilenden Sattelstücken am Rumpf anheben und lagern kann, ohne sie zu beschädigen.Of particular value in the development of the device was the knowledge of the applicant that, contrary to the prevailing opinion of the specialist world, not only lifting and storing the torpedoes in the immediate vicinity of the places where they are attached to the ticket, but feasible you can also lift and store these using weight-distributing saddle pieces on the fuselage without damaging them.

  • Figur 2 einen Schnitt II-II nach Fig. 1
  • Figur 3 eine Draufsicht der Hebevorrichtung.
Further features and advantages of the invention emerge from the description of the schematic drawings, in which views of an embodiment of the device according to the invention are shown. Show it :
  • FIG. 1 shows a side view,
  • FIG. 2 shows a section II-II according to FIG. 1
  • Figure 3 is a plan view of the lifting device.

In den Figuren ist eine Hebevorrichtung für Torpedos dargestellt, welche in ihrem grundsätzlichen Aufbau aus hydraulischen doppeltwirkenden Hubelementen 1 besteht, welche über Bolzen 3 am Hubbalken 2 angelenkt sind ; der Hubbalken 2 ist mittels Träger 6 und den Bolzen 4 und 5 mit dem Querbalken 7 gelenkig verbunden. An dem Querbalken 7 ist ein erstes, den Bolzen 8 tragendes Augenlager (nicht dargestellt) angeschweisst und ein zweites den Bolzen 8a tragendes Augenlager 14 angeschraubt. Die beiden Augenlager sind eventuell mit mehreren in Längsrichtung zum Balken 7 versetzten Löchern versehen, durch welche die Bolzen 8 und 8a durchgeschoben werden können. An den Bolzen 8 und 8a sind die Sattelstücke 9 und 9a drehbar gelagert.In the figures, a lifting device for torpedoes is shown, which in its basic structure consists of hydraulic double-acting lifting elements 1, which are articulated via bolts 3 on the walking beam 2; the walking beam 2 is articulated to the crossbar 7 by means of the support 6 and the bolts 4 and 5. A first eye bearing (not shown) carrying the bolt 8 is welded to the crossbar 7 and a second eye bearing 14 carrying the bolt 8a is screwed on. The two eye bearings are possibly provided with a plurality of holes which are offset in the longitudinal direction to the beam 7 and through which the bolts 8 and 8a can be pushed. The saddle pieces 9 and 9a are rotatably mounted on the bolts 8 and 8a.

Die Verschraubung des Äugenlagers 14 mit dem Querbalken 7 erlaubt ein müheloses Verstellen (mittels im Augenlager 14 vorgesehenen Löchern und Längslöchern) und ein schnelles Entfernen des Sattelstückes 9a. Ein genaues Anliegen der Sattelstücke ist nur gewährleistet, wenn Bogenmass, Bogenhöhe und Bogensehne der Sattelstücke auf den jeweiligen Torpedokörperradius abgestimmt sind, d. h. für verschieden Behälterdurchmesser müssen verschiedene Sattelstücke bereitgestellt werden.The screwing of the eye bearing 14 to the crossbeam 7 allows easy adjustment (by means of holes and longitudinal holes provided in the eye bearing 14) and quick removal of the saddle piece 9a. An exact fit of the saddle pieces is only guaranteed if the curve dimensions, bow height and bow string the saddle pieces are matched to the respective torpedo body radius, ie different saddle pieces must be provided for different container diameters.

An der unteren Seite eines jeden Querbalkens 7 sind zwei Stützen 10 angeschweisst (siehe Fig. 2). An jedem Querbalken 7 sind neben den Stützen 10 noch zwei Federbeine 11 befestigt, welche sich über mit zwei Stahlrädern 12 versehenen Achsen auf dem Boden abstützen. Diese Achsen verlaufen parallel zu den Hubbalken 2. Die Feder wird so dimensioniert, dass ihre Kraft ein Abheben der Vorrichtung ohne Hubbalken 2 und Hubelemente 1 ermöglicht. So ist ein Verschieben in Querrichtung in unbelastetem Zustand gegeben und ein festes Stehen auf den Stützen 10 (oder beim Anheben, auf den Hubelementen 1) unter Last sichergestellt. Die beiden Querbalken 7 sind über zwei Schräglenker 13 miteinander verbunden (siehe Fig. 3). Diese Schräglenker sind aber nur bei der Montage der Hebevorrichtung vorteilhaft. Nach der Montage sollen sie abgeschraubt werden, um das gelenkige Einstellen der Vorrichtung beim Anheben nicht zu stören.On the lower side of each crossbar 7, two supports 10 are welded (see FIG. 2). In addition to the supports 10, two suspension struts 11 are also attached to each crossbeam 7, which are supported on the floor by axles provided with two steel wheels 12. These axes run parallel to the lifting beam 2. The spring is dimensioned such that its force enables the device to be lifted without the lifting beam 2 and lifting elements 1. So there is a shift in the transverse direction in the unloaded state and a firm standing on the supports 10 (or when lifting, on the lifting elements 1) is ensured under load. The two crossbeams 7 are connected to one another via two semi-trailing arms 13 (see FIG. 3). These semi-trailing arms are only advantageous when installing the lifting device. After assembly they should be unscrewed so as not to disturb the articulated setting of the device when lifting.

Die Vorgehensweise ist folgende :

  • Die beiden Hubbalken 2 und die daran befestigten Linearmotoren 1 werden nach dem Lösen der Bolzen 5 mit Hilfe eines Kranes entfernt. Die Sattelstücke 9a werden ebenfalls abgebaut. Dies geschieht durch Lösen des Augenlagers 14 vom Querbalken 7. Die Federbeine 11 heben die restlichen Teile der Vorrichtung vom Boden ab, so dass diese sich quer zu den Schienen 15 aus der Bahn des Zuges schieben lässt. Ein Torpedowagen wird in die Halle eingefahren, bis der Rumpf des Torpedos sich auf Höhe der Hebevorrichtung befindet, welche daraufhin unter den Torpedo geschoben wird. Das Sattelstück 9a wird in Abhängigkeit von dem Querschnitt des Torpedorumpfes am Querbalken 7 febestigt. Die Hubbalken 2 werden nacheinander mit einem Kran in ihre Arbeitsstellung gebracht, so dass die Träger 6 in die dafür vorgesehenen Oeffnungen in den Querbalken 7 eingeführt werden und die Bolzen 5 durchgeschoben und gesichert werden können. Die Vorrichtung ruht nun auf den Stützen 10. Anschliessend werden die Linearmotoren betätigt, wobei zu bemerken ist, dass dank der Bolzen 3, 4 und 5 die Vorrichtung sich allen Neigungen und der genauen Lage des Torpedorumpfes anpassen kann, so dass die 4 Sattelstücke gezielt zum Tragen gelangen. Beim nachträglichen Befestigen vom Torpedokörper an die Fahrschemel sind diese Einstellmöglichkeiten besonders vorteilhaft. Die beiden Fahrschemel werden gleichzeitig vom leicht angehobenen Torpedokörper gelöst und herausgerollt, dann wird der Druck in den Linearmotoren vermindert und die Stützen 10 gelangen zum Tragen, bis die einige Tage dauernden Ueberholungsarbeiten abgeschlossen sind. Um eine längere Hitzeeinwirkung während den Ueberholungsarbeiten auf die Linearmotoren zu vermeiden, können gegebenenfalls die Hubbalken 2 mit den daran befestigten Linearmotoren sofort nach dem Absetzvorgang entfernt werden.
The procedure is as follows:
  • The two walking beams 2 and the linear motors 1 attached to them are removed by loosening the bolts 5 using a crane. The saddle pieces 9a are also removed. This is done by loosening the eye bearing 14 from the crossbeam 7. The spring struts 11 lift the remaining parts of the device off the floor, so that it can be pushed transversely to the rails 15 out of the train's path. A torpedo car is driven into the hall until the torso of the torpedo is at the level of the lifting device, which is then pushed under the torpedo. The saddle piece 9a is fastened to the crossbar 7 depending on the cross section of the torpedo fuselage. The walking beams 2 are brought into their working position one after the other with a crane, so that the supports 6 are inserted into the openings provided for this purpose in the crossbeam 7 and the bolts 5 can be pushed through and secured. The device now rests on the supports 10. Then the linear motors are actuated, whereby it should be noted that, thanks to the bolts 3, 4 and 5, the device can adapt to all inclinations and the exact position of the torpedo fuselage, so that the 4 saddle pieces are targeted to Arrive. These settings are particularly advantageous when retrofitting the torpedo body to the subframe. The two subframes are simultaneously released from the slightly raised torpedo body and rolled out, then the pressure in the linear motors is reduced and the supports 10 come into play until the overhaul work which lasts for a few days is completed. In order to avoid prolonged exposure to heat during the overhaul work on the linear motors, the lifting beams 2 with the linear motors attached to them can be removed immediately after the setting process.

Zwecks Kosteneinsparung bei der Herstellung einer solchen Hebevorrichtung für schwere Lasten besteht die Möglichkeit einige oder auch mehrere gelenkige Verbindungen mittels Bolzen, durch starre Verbindungen (Verschraubungen oder Schweissen) zu ersetzen. In diesem Fall wird das Anpassen der Sattelstücke an den Torpedorumpf von der Elastizität des verwendeten Materials abhängig, welches entsprechend dimensioniert sein muss.In order to save costs in the manufacture of such a lifting device for heavy loads, it is possible to replace some or more articulated connections by means of bolts by rigid connections (screw connections or welding). In this case, the adaptation of the saddle pieces to the torpedo hull depends on the elasticity of the material used, which must be dimensioned accordingly.
