Description

Die Erfindung betrifft einen Transporthubwagen für schwere Lasten, insbesondere für Konverterwechselgefäße der Stahlerzeugung, mit einem beim Umsetzen in verschiedene Fahrtrichtungen gegenüber einem Drehrahmen drehbaren Fahrrahmen und mit einem gegenüber dem Fahrrahmen mittels Druckmittelzylinder heb- und senkbaren Hubrahmen.The invention relates to a transport pallet truck for heavy loads, in particular for converter change vessels of steel production, with a moving frame that can be rotated relative to a rotating frame when converted into different directions of travel and with a lifting frame that can be raised and lowered relative to the moving frame by means of a pressure medium cylinder.

Ein Transporthubwagen dieser Art ist aus der DE-AS 27 25 123 bekannt. Bei diesem bekannten Transporthubwagen ist das Konverterwechselgefäß auf einem Hubrahmen abgestützt, der über Zugglieder oder Druckmittelzylinder an einem gegenüber dem Fahrrahmen heb- und senkbaren Querhaupt angelenkt ist; was eine aufwendige und nicht sehr stabile Konstruktion bedingt. Der Drehrahmen ist bei dieser bekannten Konstruktion unabhängig vom Hubrahmen am Fahrrahmen drehbar gelagert und muß beim Umsetzen des Fahrzeuges bei einer Schienenkreuzung mittels eigener Druckmittelzylinder gegenüber dem Boden abgestützt werden. Am Hubrahmen selbst kann das Konvertergefäß mittels kurzhubiger Kolbenzylindereinheiten, die eine Anpassung des Gefäßes an seine Halterung ermöglichen, abgestützt sein. Diese Kolbenzylindereinheiten ermöglichen jedoch kein Anheben und Absenken des Gefäßes.A transport pallet truck of this type is known from DE-AS 27 25 123. In this known transport pallet truck, the converter change vessel is supported on a lifting frame which is articulated via tension members or pressure medium cylinders to a crosshead which can be raised and lowered with respect to the traveling frame; which requires a complex and not very stable construction. In this known construction, the rotating frame is rotatably mounted on the traveling frame independently of the lifting frame and must be supported against the ground by means of its own pressure medium cylinder when the vehicle is moved at a rail crossing. The converter vessel can be supported on the lifting frame itself by means of short-stroke piston-cylinder units, which enable the vessel to be adapted to its holder. However, these piston-cylinder units do not allow the vessel to be raised or lowered.

Aus der DE-PS 24 07 073 ist weiters ein Transporthubwagen bekannt, bei dem innerhalb des Fahrrahmens mehrere konzentrische Drehrahmen vorgesehen sind, die sich in bestimmten Winkelstellungen auf dem Fahrrahmen abstützen und in anderen Winkelstellungen durch den Rahmen hindurchtreten können. Ein- und ausziehbare Huborgane mit kleinerer Hubhöhe als der gesamte Hubweg der Last sind an den Drehrahmen angeordnet. Der Konverter ruht bei diesem bekannten Transporthubwagen auf einer mit einem oberen Drehrahmen verbundenen Platte auf; das Heben bzw. Senken erfolgt in mehreren Schritten, wobei jeweils Sperrmittel, z.B. hydraulische Zylinder, vorgesehen sind, um den Konverter zwischen den Verstellschritten in bestimmter Höhe zu halten. Hierfür ist eine genaue Steuerung notwendig, wodurch die Einrichtung aufwendig wird.From DE-PS 24 07 073 a transport pallet truck is also known, in which several concentric rotating frames are provided within the traveling frame, which are supported in certain angular positions on the traveling frame and can pass through the frame in other angular positions. Retractable and retractable lifting elements with a smaller lifting height than the entire lifting path of the load are arranged on the rotating frame. In this known transport pallet truck, the converter rests on a plate connected to an upper rotating frame; the lifting or lowering takes place in several steps, locking means, for example hydraulic cylinders, being provided in each case in order to keep the converter at a certain height between the adjustment steps. This requires precise control, which makes the setup complex.

Die Erfindung bezweckt die Vermeidung dieser Schwierigkeiten und stellt sich die Aufgabe, einen robusten, konstruktiv einfach ausgebildeten Transporthubwagen vorzusehen, bei dem große Hubhöhen erreicht werden können, ohne Teleskopzylinder verwenden und ohne das Heben in mehreren Schritten durchführen zu müssen. Weiters soll es möglich sein, den Transporthubwagen an Kreuzungen umzusetzen, ohne dazu eigene Druckmittelzylinder vorzusehen.The invention aims to avoid these difficulties and has as its object to provide a robust, structurally simple transport pallet truck in which large lifting heights can be achieved without using telescopic cylinders and without having to carry out the lifting in several steps. Furthermore, it should be possible to move the transport pallet truck at intersections without providing its own pressure medium cylinders.

Diese Aufgabe wird bei einem Transporthubwagen der eingangs beschriebenen Art dadurch gelöst, daß in dem Hubrahmen einerseits nach unten wirkende, am Fahrrahmen abgestützte Druckmittelzylinder und anderseits nach oben wirkende, das Konverterwechselgefäß stützende Druckmittelzylinder befestigt sind und daß der Drehrahmen an dem Hubrahmen drehbar gelagert ist.This object is achieved with a transport pallet of the initially described type in that on the one hand mounted in the lifting frame by acting down, is supported on the traveling frame hydraulic cylinder and on the other hand, upward-acting, the converter exchange vessel supporting pressure medium cylinder and that the D rehrahmen rotatably supported on the lifting frame.

Durch die Befestigung der gegenläufigen, d.h. nach oben bzw. nach unten wirkenden Druckmittelzylinder an einem einteiligen starren Hubrahmen ist der Transporthubwagen besonders stabil. Die drehbare Lagerung des Drehrahmens am Hubrahmen bewirkt, daß der Transporthubwagen an einer Schienenkreuzung durch Betätigung der den Hubrahmen am Fahrrahmen abstützenden Druckmittelzylinder umgesetzt werden kann, wodurch für diesen Zweck keine eigenen Druckmittelzylinder vorgesehen sein müssen.The transport pallet truck is particularly stable due to the fastening of the counter-rotating pressure medium cylinders, ie those that act upwards or downwards, on a one-piece rigid lifting frame. The rotatable mounting of the rotating frame on the lifting frame causes the transport pallet truck to be implemented at a rail crossing by actuating the pressure medium cylinder supporting the lifting frame on the moving frame that can, whereby no separate pressure medium cylinders have to be provided for this purpose.

Nach einer bevorzugten Ausführungsform ist der Drehrahmen an der Unterseite des Hubrahmens mittels eines Druckkräfte aufnehmenden Lagers gelagert und direkt auf dem Boden abstützbar.According to a preferred embodiment, the rotating frame is mounted on the underside of the lifting frame by means of a bearing which absorbs compressive forces and can be supported directly on the floor.

In der Zeichnung ist ein Ausführungsbeispiel des erfindungsgemäßen Transporthubwagens dargestellt, wobei Fig. 1 eine Seitenansicht in abgesenkter Stellung des Konverters und Fig. 2 in angehobener Stellung des Konverters, teilweise geschnitten, wiedergibt. Fig. 3 zeigt einen Grundriß und in Fig. 4 ist eine Seitenansicht in angehobener Stellung des Fahrrahmens bei abgesenktem Konverter gezeigt.In the drawing, an embodiment of the transport truck according to the invention is shown, wherein Fig. 1 shows a side view in the lowered position of the converter and Fig. 2 in the raised position of the converter, partially in section. Fig. 3 shows a plan and in Fig. 4 is a side view in the raised position of the traveling frame with the converter lowered.

In der Zeichnung ist mit 1 der Fahrrahmen des Transporthubwagens bezeichnet, der über Laufrad-Balanciers 2 mit Rädern 3 auf Schienen 4 geführt ist. An dem Fahrrahmen 1 ist eine Anzahl von hydraulischen Druckmittelzylindern 5 vorgesehen, deren unteres Kolbenende 6 an dem Fahrrahmen befestigt ist. Mit dem oberen zylinderseitigen Ende 7 ist der Hubrahmen 8 des allgemein mit 9 bezeichneten Hubdrehwerks verbunden. An der Unterseite 10 des Hubrahmens ist mittels eines Druckkräfte aufnehmenden Lagers 11, z.B. eines Wälzlagers, der Drehrahmen 12 gelagert, der an seiner Unterseite eine ringförmige Abstützfläche 13 aufweist. Im Hubrahmen 8 ist eine Anzahl weiterer hydraulischer Druckmittelzylinder 14 angeordnet, u.zw. mit der Zylinderseite an dem Hubrahmen befestigt, wogegen die Kolben 15 nach oben ausschiebbar sind. Auf den Kolbenenden stützen sich die Pratzen 16 des Konverters 17 ab. An dem Drehrahmen ist der Drehantrieb 18 angeordnet, der mit einem Ritzel 19 in eine Verzahnung 20 des Drehrahmens 12 eingreift, wie aus Fig. 3 ersichtlich ist.In the drawing, 1 denotes the traveling frame of the transport pallet truck, which is guided by wheels 3 on rails 4 via wheel balancers 2. A number of hydraulic pressure medium cylinders 5 are provided on the traveling frame 1, the lower piston end 6 of which is fastened to the traveling frame. The lifting frame 8 of the lifting slewing gear, generally designated 9, is connected to the upper end 7 on the cylinder side. On the underside 10 of the lifting frame is a bearing 11, e.g. a rolling bearing, the rotating frame 12 is mounted, which has an annular support surface 13 on its underside. A number of further hydraulic pressure medium cylinders 14 are arranged in the lifting frame 8, etc. attached to the lifting frame with the cylinder side, whereas the pistons 15 can be pushed out upwards. The claws 16 of the converter 17 are supported on the piston ends. The rotary drive 18 is arranged on the rotating frame and engages with a pinion 19 in a toothing 20 of the rotating frame 12, as can be seen from FIG. 3.

Die Funktion des erfindungsgemäßen Transporthubwagens ist die folgende:

  • Wenn der Transporthubwagen aus der in Fig. 1 gezeigten Stellung auf einer Schienenkreuzung in eine andere Fahrtrichtung umgesetzt werden soll, wird das Hubdrehwerk 9 abgesenkt, sodaß es mit der ringförmigen Abstützfläche 13 des Drehrahmens 12 auf dem Boden aufsteht. Dann wird der Druckmittelzylinder 5 betätigt, wodurch der Fahrrahmen 1 um ein Stück, welches in Fig. 4 mit 21 bezeichnet ist, angehoben wird, sodaß die Spurkränze der Räder über den Schienen liegen. Der Konverter 17, der Drehrahmen 12 und der Hubrahmen 8 bleiben in Ruhestellung. Dann werden durch Betätigung des Drehwerks 18 der Fahrrahmen 1 mit dem Hubrahmen 8 und dem Konverter 17 in die neue Fahrtrichtung gedreht, und durch Betätigung des Zylinders 5 in Gegenrichtung die Räder auf das andere Gleis der Kreuzung abgesenkt, wobei der Drehrahmen 12 vom Boden wieder um ein Stück abgehoben wird. Sodann wird der Transporthubwagen mit dem Konverter in einen neuen Stand (Blasstand oder Reparaturstand) gefahren, und durch Betätigung beider Zylinder 5 und 14 in die in Fig. 2 gezeigte Stellung gehoben und in die örtlichen Standlager eingehängt. Dann wird durch umgekehrte Betätigung des Hubdrehwerks der entlastete Transporthubwagen weggefahren. Bei der in der Zeichnung dargestellten Ausführungsform sind die nach oben wirkenden Druckmittelzylinder am Hubrahmen 8 befestigt. Es ist jedoch auch möglich, diese nach oben wirkenden Hubeinrichtungen am Drehrahmen 12 vorzusehen.
The function of the transport pallet truck according to the invention is as follows:
  • If the transport pallet truck is to be moved from the position shown in FIG. 1 to a different direction of travel at a rail crossing, the lifting slewing gear 9 is lowered so that it stands on the ground with the annular support surface 13 of the rotating frame 12. Then the pressure medium cylinder 5 is actuated, whereby the traveling frame 1 is raised by a piece, which is designated in FIG. 4 with 21, so that the wheel flanges of the wheels lie above the rails. The converter 17, the rotating frame 12 and the lifting frame 8 remain in the rest position. Then, by operating the slewing gear 18, the traveling frame 1 with the lifting frame 8 and the converter 17 are rotated in the new direction of travel, and by actuating the cylinder 5 in the opposite direction, the wheels are lowered onto the other track of the intersection, the rotating frame 12 again from the ground a piece is lifted off. The transport pallet truck with the converter is then moved to a new stand (blow stand or repair stand), and is raised to the position shown in FIG. 2 by actuating both cylinders 5 and 14 and hooked into the local stand storage. Then the relieved transport pallet truck is moved away by reverse actuation of the lifting slewing gear. In the embodiment shown in the drawing, the pressure medium cylinders acting upwards are attached to the lifting frame 8. However, it is also possible to provide these upward-acting lifting devices on the rotating frame 12.

Durch die in Gegenrichtung ausschiebbaren Kolben 6 bzw. 15 der hydraulischen Hubmittel wird erfindungsgemäß eine große Hubhöhe auf einfache Weise erreicht, ohne daß aufwendige Sperr- und Steuerungsmaßnahmen notwendig sind, wobei auch die Stabilität infolge der Auflagerung der Konverterpratzen auf den Kolbenenden, verglichen mit den bekannten Einrichtungen, verbessert ist, u.zw. deshalb, weil der Schwerpunkt des Konverters sich etwa in Höhe der Auflagerung befindet.Due to the piston 6 or 15 of the hydraulic lifting means, which can be pushed out in the opposite direction, a large lifting height is achieved in a simple manner according to the invention, without complex locking and control measures being necessary, the stability due to the support of the Converter claws on the piston ends, compared to the known devices, is improved, etc. This is because the center of gravity of the converter is approximately at the level of the support.
