Abstract

The wheel unit has several wheel sets capable of passing round curves, running in the rails on bogies. The wheel sets (2-5) are relieved by at least one supporting wheel set (7) with two wheels, which can be raised and lowered on the vehicle. Its support wheels can be lowered from a rest position above the rails to a working position in which each wheel acts on the rail at a pressure which can be set.

Description

Die Erfindung betrifft ein Fahrgestell für ein schienengebundenes Fahrzeug zum Transportieren frei verfahrbarer Lasten, insbesondere das Fahrgestell eines Eisenbahnkranes, mit mehreren in Drehgestellen aufgenommenen kurvengängigen Radsätzen, die in einem oder mehreren Fahrwerksrahmen gelagert auf den Fahrschienen abrollen.The invention relates to a chassis for a rail-bound vehicle for Transporting freely movable loads, especially the chassis of one Railway cranes, with several curved bends recorded in bogies Wheelsets that are stored in one or more undercarriage frames Roll off the rails.

Schienengebundene Fahrzeuge der gattungsgemäßen Art zeichnen sich dadurch aus, daß sie schnell und einfach auf Schienen zu ihren Einsatzorten transportierbar sind, wo sie dann, auch mit aufgenommener Last frei verfahrbar manövrierbar sind. Fahrzeuge dieser Art sind beispielsweise Eisenbahnkrane, die im Gleis- und Brückenbau sowie als Bergekrane eingesetzt werden können. Neben der Forderung, die Fahrzeuge auf dem Schienenweg schnell zum Einsatzort transportieren zu können, müssen mit den Fahrzeugen am Einsatzort oft große Lasten auf engstem Raum manövriert werden können.Rail-bound vehicles of the generic type are characterized by this from that they can be quickly and easily transported on rails to their locations are where they can be freely maneuvered, even with a load. Vehicles of this type are, for example, railway cranes, which are in the track and Bridge construction as well as recovery cranes can be used. In addition to the requirement transport the vehicles quickly to the place of use by rail can often have to carry heavy loads in the tightest of places with the vehicles Space can be maneuvered.

Hohe Traglasten erfordern beispielsweise bei schienengebundenen Kranen oder dergl. eine entsprechende große Anzahl von Radsätzen, damit das Eigengewicht des Fahrzeuges und die Traglast auf die Schienen übertragen werden können. Eine große Anzahl von Radsätzen, die wegen der Kurvengängigkeit des Fahrzeuges jeweils paarweise in Drehgestellen anzuordnen sind, ist nicht nur teuer und vergrößert die Gesamtfahrzeuglänge, sie erhöht auch das Leergewicht des Fahrzeuges. Das Leergewicht des Fahrzeuges ist aber nicht beliebig erhöhbar; denn durch die Vorschriften der Betreiber des Schienennetzes sowie die Belastbarkeit der Fahrschienen und des Untergrundes sind Grenzen gesetzt. Damit ist aber auch gleichzeitig die Traglast limitiert, die sich zu dem Eigengewicht des Fahrzeuges addiert
Jede Erhöhung des Eigengewichtes des Fahrzeuges bedeutet letztlich eine Verringerung der Traglast.
In the case of rail-bound cranes or the like, for example, high payloads require a correspondingly large number of wheel sets so that the weight of the vehicle and the payload can be transferred to the rails. A large number of wheel sets, which must be arranged in pairs in bogies due to the vehicle's ability to negotiate curves, is not only expensive and increases the overall vehicle length, it also increases the curb weight of the vehicle. However, the empty weight of the vehicle cannot be increased at will; Because the regulations of the operators of the rail network and the resilience of the rails and the underground set limits. However, this also limits the payload, which adds to the weight of the vehicle
Any increase in the vehicle's own weight ultimately means a reduction in the load capacity.

Man muß deshalb versuchen, das Eigengewicht des Fahrzeuges zugunsten der Traglast möglichst gering zu halten. Die deutsche Patentschrift 196 54 521 beispielsweise schlägt vor, den über die gesamte Fahrzeuglänge erstreckenden Fahrzeugrahmen aufzuteilen und dadurch leichter zu bauen. Leichter zu bauen kann aber nachteilig die Stabilität beeinflussen, so daß nach anderen Wegen gesucht wurde, um die Tragkraft des gattungsgemäßen Fahrzeuges zu erhöhen.One must therefore try to get the weight of the vehicle in favor of To keep the load as low as possible. German patent 196 54 521 For example, suggests the one that extends over the entire length of the vehicle Split vehicle frame and thus easier to build. Can be built easier but adversely affect stability, so that other ways searched was to increase the load capacity of the generic vehicle.

Aufgabe der vorliegenden Erfindung ist es, ein Fahrgestell für ein schienengebundenes Fahrzeug zum Transportieren frei verfahrbarer Lasten zu schaffen, das ohne das Eigengewicht des Fahrzeuges in starkem Maße zu erhöhen, hohe Traglasten bei guter Manövrierbarkeit des Fahrzeuges erreicht. Gleichzeitig soll die Lösung kostengünstig sein.The object of the present invention is to provide a chassis for a rail-bound vehicle for transporting freely movable loads create that without increasing the weight of the vehicle to a large extent, high loads with good maneuverability of the vehicle. At the same time the solution be inexpensive.

Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, die Radsätze des Fahrzeuges dadurch zu entlasten, daß mindestens ein aus zwei Stützrädern bestehender Stützradsatz vorgesehen ist, der heb- und senkbar am Fahrzeug befestigt ist und dessen Stützräder aus einer Ruhestellung oberhalb der Schiene in eine Wirkstellung absenkbar sind, in der jedes Stützrad mit einstellbarem Druck auf einem Gleis der Schiene aufliegt.To achieve the object, the wheelsets of the invention are proposed To relieve the vehicle in that at least one of two support wheels existing jockey wheel set is provided, which can be raised and lowered on the vehicle is attached and the support wheels from a rest position above the rail in an active position can be lowered in which each support wheel with adjustable pressure rests on a track of the rail.

Während bisher die frei verfahrbaren Traglasten eines gattungsgemäßen Fahrzeuges nur durch zusätzliche permanent mitrollende Radsätze mit entsprechend hohem Eigengewicht und Verlängerung des Gesamtfahrzeuges erhöht werden konnten, wird durch die vorliegende Erfindung die Traglasterhöhung ohne Verlängerung des Schienenfahrgestelles dadurch ermöglicht, daß mit den erfindungsgemäßen Stützradsätzen die eigentlichen Radsätze während des Lasteinsatzes entlastet werden. Die Stützräder des Stützradsatzes oder der Stützradsätze werden einfach auf die Schienen abgesenkt und übernehmen einen Teil der Traglast, für die sonst ein eigener doppelter Radsatz erforderlich gewesen wäre. Während des Schienentransports des schienengebundenen Fahrzeuges ist der Stützradsatz angehoben; das Fahrzeug bewegt sich auf den herkömmlichen Radsätzen und kann mit hohen Transportgeschwindigkeiten zum Einsatzort gebracht werden. Das Maß der Entlastung der Radsätze am Einsatzort kann dadurch bestimmt werden, daß der Auflagedruck des Stützradsatzes auf der Schiene zwischen 0 und einem Maximum (beispielsweise 17 t) einstellbar ist, eine entsprechende Steuerung kann vorsehen, daß der prozentuale Anteil der von dem Stützradsatz aufzunehmenden Last stets gleichgehalten wird.While previously the freely movable loads of a generic vehicle only thanks to additional wheelsets with a correspondingly high roll Dead weight and lengthening of the entire vehicle could be increased by the present invention, the payload increase without extending the Rail chassis thereby allows that with the invention Jockey wheel sets relieved the actual wheel sets during load application become. The jockey wheels of the jockey wheel set or the jockey wheel sets become simple lowered onto the rails and take on part of the payload, otherwise for one own double wheelset would have been necessary. During the The support wheel set is the rail transport of the rail-bound vehicle raised; the vehicle moves on the conventional wheelsets and can brought to the place of use at high transport speeds. The measure of Relief of the wheel sets on site can be determined by the fact that the Contact pressure of the jockey wheel set on the rail between 0 and a maximum (for example 17 t) is adjustable, a corresponding control can provide that the percentage of the load to be borne by the jockey wheel set always is kept the same.

Der Stützradsatz kann den Radsätzen unmittelbar benachbart am Fahrwerksrahmen angeordnet sein, wobei die Stützräder vorzugsweise geringeren Durchmesser als die eigentlichen Räder der Radsätze aufweisen. Das spart Gewicht und Raum für die Unterbringung der Stützradsätze, von denen vorzugsweise mindestens zwei an beiden Fahrzeugseiten vorgesehen sind.The jockey wheel set can be directly adjacent to the wheel sets on the chassis frame be arranged, the support wheels preferably smaller diameter than that have actual wheels of the wheel sets. This saves weight and space for them Housing the support wheel sets, of which preferably at least two are provided on both sides of the vehicle.

In einer günstigen Ausgestaltung der Erfindung ist vorgesehen, den Stützradsatz zwischen den Radsätzen des Fahrgestells anzuordnen. Es bietet sich an, die Anordnung im Bereich unterhalb des Drehzapfens des Drehgestells vorzunehmen, weil die Entlastung der Radsätze dort am effektivsten ist.In a favorable embodiment of the invention, the support wheel set is provided to be placed between the wheelsets of the chassis. It lends itself to that Arrange in the area below the bogie pivot, because the relief of the wheel sets is most effective there.

Der Stützradsatz kann nach einer weiteren Ausgestaltung der Erfindung an einer Schwinge angeordnet und hydraulisch oder hydropneumatisch heb- und senkbar sein. Entsprechende Druckmittelzylinder können zwischen Schwinge und Fahrgestell in der Nähe der Stützräder angreifen, wobei die Druckmittelzufuhr druckgeregelt erfolgt, um die Stützlast des Stützradsatzes einstellen zu können.According to a further embodiment of the invention, the support wheel set can be attached to a Swing arm arranged and be raised or lowered hydraulically or hydropneumatically. Corresponding pressure cylinder can be between the swing arm and chassis in the Attack near the support wheels, whereby the pressure medium supply is pressure regulated to to be able to adjust the drawbar load of the jockey wheel set.

Als günstig wird angesehen, wenn nach einem weiteren Merkmal der Erfindung die Raddrücke des Stützradsatzes auf jeder Fahrzeugseite separat einstellbar sind, durch diese Maßnahme können die sich aus dem Manövrieren der Last ergebenden unterschiedlichen Drücke auf den jeweiligen Schienen separat erfaßt und die Stützräder entsprechend gesteuert werden.It is considered favorable if, according to a further feature of the invention Wheel pressures of the jockey wheel set can be set separately on each side of the vehicle this measure can be taken from maneuvering the load different pressures on the respective rails recorded separately and the Jockey wheels are controlled accordingly.

In einer anderen Ausführung der Erfindung ist vorgesehen, die Stützräder jedes Stützradsatzes einzeln an Radführungshebeln anzuordnen, die dann ihrerseits mit den Druckmittelzylindern der Hydraulik oder Hydropneumatik verbunden sind. In another embodiment of the invention, the support wheels each Jockey wheel set to be arranged individually on the wheel control levers, which in turn then with the hydraulic or hydropneumatic pressure medium cylinders are connected.

Zum Ausgleich von Radienunterschieden jedes Radsatzes beim Durchfahren von Kurvenstrecken ist vorzugsweise vorgesehen, die Stützräder jedes Stützradsatzes in Achsrichtung verschiebbar zu lagern.To compensate for differences in the radii of each wheel set when driving through Curve sections are preferably provided, the support wheels of each support wheel set in Axially slidable to store.

Schließlich ist erfindungsgemäß alternativ vorgesehen, die Stützräder anzutreiben, um beim Verfahren unter Last eine Verfahrhilfe zur Verfügung zu haben.Finally, it is alternatively provided according to the invention to drive the support wheels, in order to have a travel aid available when moving under load.

Durch die vorliegende Erfindung ergibt sich ein kurzes und preisgünstiges Schienenfahrgestell, das dennoch hohe Tragkräfte aufweist. Dies wird mit einfachen Mitteln erreicht, die es gestatten, die auf die Radsätze wirkenden Tragkräfte beim Verfahren des Fahrzeuges unter Last auf mindestens einen zusätzlichen Stützradsatz zu verteilen, um dadurch entweder die Radsätze des Fahrzeuges zu entlasten oder die Tragkraft erhöhen zu können. Selbstverständlich können die Stützräder auch in größerer Anzahl an geeigneter Stelle des Fahrgestells angeordnet werden. Die Maßnahmen sind einfach und gegenüber zusätzlichen Radsätzen gewinnsparend, so daß sich eine für den Kranbetreiber günstige Lösung ergibt.The present invention results in a short and inexpensive Rail chassis, which nevertheless has high load capacities. This is done with simple Means achieved that allow the load acting on the wheelsets at Moving the vehicle under load on at least one additional jockey wheel set distribute to either relieve the wheelsets of the vehicle or to be able to increase the load capacity. Of course, the support wheels can also be in larger numbers can be arranged at a suitable location on the chassis. The Measures are simple and profitable compared to additional wheelsets, so that there is a favorable solution for the crane operator.

In Figur 1 ist mit 1 das Fahrgestell eines Schienenkrans dargestellt, von dem die vier Radsätze 2 bis 5 gezeigt sind. Der Schienenkran hat gewöhnlich mehrere Radsätze, die jeweils zu Gruppen in Drehgestellen gelagerter Radsätze zusammengefaßt sind. 1 shows the chassis of a rail crane, of which the four Wheelsets 2 to 5 are shown. The rail crane usually has multiple sets of wheels, which are grouped together in bogies of wheelsets.

Zwischen den Radsätzen 3 und 4 ist am Fahrgestell 1 ein Stützradsatz 7 angeordnet, der in einer Schwinge 10 gelagert ist, die an einer beidseitig am Fahrgestell 1 befestigten Traverse 6 um eine horizontalen Schwenkachse 8 verschwenkbar ist. Am freien Ende jeder Schwinge 10 greifen Kolben-Zylindereinheit 9 mit ihren kolbenstangenseitigen Augen 11 an, die zylinderseitigen Enden der Kolben-Zylindereinheiten 9 sind mit Augen 12 am Fahrgestell 1 angebolzt. Durch Betätigen der Kolben-Zylindereinheit 9 kann über den durch die horizontale Schwenkachse 8 gebildeten Gelenkpunkt der Schwinge 10 der Stützradsatz 7 auf die Schiene 13 gedrückt werden, so daß die Radsätze 2 bis 5 durch den Stützradsatz 7 entlastet werden. Durch Beaufschlagung der Kolben-Zylindereinheit 9 in entgegengesetzter Richtung wird - wie in Figur 2 dargestellt- der an der Schwinge 10 gelagerte Stützradsatz beim Verschwenken der Schwinge 10 um den Gelenkpunkt 8 angehoben und dabei von der Schiene 13 abgehoben. In dieser Stellung kann das Fahrzeug transportiert werden, ohne daß der Stützradsatz 7 eine Funktion hat.A support wheel set 7 is arranged on the chassis 1 between the wheel sets 3 and 4, which is mounted in a rocker arm 10 which is attached to the chassis 1 on both sides attached cross member 6 is pivotable about a horizontal pivot axis 8. At the free end of each rocker arm 10 engage piston-cylinder unit 9 with their piston rod-side eyes 11, the cylinder-side ends of the piston-cylinder units 9 are bolted to the chassis 1 with eyes 12. By actuating the piston-cylinder unit 9 can through the horizontal Pivot axis 8 formed hinge point of the rocker 10 of the support wheel set 7 on the Rail 13 are pressed so that the wheel sets 2 to 5 by the support wheel set 7th be relieved. By acting on the piston-cylinder unit 9 in in the opposite direction, as shown in FIG. 2, is on the rocker 10 Supported wheel set when pivoting the rocker 10 about the hinge point 8 raised and lifted off the rail 13. In this position it can Vehicle are transported without the support wheel set 7 has a function.

In Figur 3 ist in einem Querschnitt durch die Schwinge 10 die Lagerung des Stützradsatzes 7 dargestellt. Das Stützrad 7a ist auf einer mit dem (nicht dargestellten) zweiten Stützrad gemeinsamen Achse 14 aufgesetzt, die bei 15 gelagert ist. Der Anlenkpunkt der Kolben-Zylindereinheit 9 ist bei 11 angedeutet.In Figure 3 is a cross section through the rocker 10, the storage of Support wheel set 7 shown. The jockey wheel 7a is on one with the (not shown) second support wheel common axis 14 placed at 15th is stored. The articulation point of the piston-cylinder unit 9 is indicated at 11.

Eine Variante der erfindungsgemäßen Stützradsatzlagerung ist in Figur 4 dargestellt. Hier ist das Stützrad 7a mit einem Achsschaft 16 in dem Radführungshebel 17 gelagert, der ebenfalls um die horizontale Schwenkachse 8 am Fahrgestell 1 verschwenkbar ist, wozu die Kolben-Zylindereinheit 9 mit dem kolbenstangenseitigen Auge bei 11 angreift. Bei dieser Lösung lassen sich die Stützräder 7a des Stützradsatzes 7 einzeln weg- und kraftgesteuert bewegen, so daß Neigungsausgleich an den entgegengesetzten Seiten des Eisenbahnkranes möglich ist.A variant of the support wheel set bearing according to the invention is shown in Figure 4. Here is the support wheel 7a with an axle shaft 16 in the wheel guide lever 17th stored, which is also about the horizontal pivot axis 8 on the chassis 1st is pivotable, for which purpose the piston-cylinder unit 9 with the piston rod side Eye attacks at 11. In this solution, the support wheels 7a of the Move the jockey wheel set 7 individually and force-controlled, so that Tilt compensation possible on opposite sides of the railway crane is.

In Figur 5 ist in einem Querschnitt durch das Fahrgestell die Anordnung des Stützradsatzes 7 erkennbar gemacht. Der Stützradsatz ist unmittelbar benachbart den Rädern des Radsatzes 3 am Fahrzeugrahmen 1 befestigt, wobei die Stützräder 7a in der angehobenen Stellung dargestellt sind. In Figure 5 is a cross section through the chassis of the arrangement of Jockey wheel set 7 made recognizable. The jockey wheel set is immediately adjacent to the Wheels of the wheelset 3 attached to the vehicle frame 1, the support wheels 7a in the raised position are shown.

Die Erfindung ermöglicht es einem Eisenbahnkran mit angehobenen Stützradsatz 7, im Zugverband zur Einsatzstelle transportiert zu werden; die Baulänge des Eisenbahnkranes kann relativ kurz gehalten werden, da zunächst nur das Eigengewicht des Fahrzeugkranes zu transportieren ist. An der Einsatzstelle wird durch Betätigen der Kolben-Zylindereinheit 9 der Stützradsatz 7 auf die Schienen 13 abgesenkt und übernimmt beim Aufnehmen und Verfahren einer Last ein Teil der aus der Last resultierenden Kräfte, so daß die Radsätze 2, 3, 4 und 5 deutlich entlastet werden. Dabei baut der Stützradsatz relativ klein; denn die Stützräder 7a sind in ihrem Durchmesser deutlich kleiner als die Räder der Radsätze 2 bis 5. Dementsprechend ist die erfindungsgemäße Einrichtung auch leichter als ein weiteres Drehgestell mit zwei Radsätzen, so daß eine Tragkrafterhöhung ohne die sonst deutliche Erhöhung des Eigengewichtes ermöglicht wird.The invention enables a railway crane with a raised jockey wheel set 7, to be transported to the site in the train association; the overall length of the Railway cranes can be kept relatively short, because initially only that The dead weight of the mobile crane is to be transported. At the job site by operating the piston-cylinder unit 9 of the support wheel set 7 on the rails 13 lowered and takes over part of the when picking up and moving a load the load resulting forces, so that the wheel sets 2, 3, 4 and 5 significantly relieved become. The jockey wheel set is relatively small; because the support wheels 7a are in their Diameter significantly smaller than the wheels of wheel sets 2 to 5. Accordingly the device according to the invention is also lighter than another bogie two wheelsets, so that an increase in load capacity without the otherwise significant increase weight is enabled.
