Description

Die Erfindung bezieht sich auf einen Tiefladewaggon für Huckepackverkehr mit einer zum Beladen seitlich ausfahrbaren Tiefladebrücke gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a flatbed wagon for piggyback transport with a flatbed bridge that can be extended laterally for loading. According to the preamble of patent claim 1.

In der Praxis bekannte Tiefladewaggons dieser Art für Huckepackverkehr weisen eine Tiefladebrücke auf, die von einem eigenen auf den Fahrgestellen gelagerten Trägerrahmen gelagert ist. In diesem Trägerrahmen sind Führungen angeordnet, die das Ein- und Ausfahren der Tiefladebrücke ermöglichen. Nachteilig an dieser Bauart ist, daß durch die Trägerrahmenkonstruktion der Waggon schwer ist und die Ladefläche der Tiefladebrücke höher als bei konventionellen Tiefladewaggons liegt. Bei einem Gleisfahrzeug für den innerbetrieblichen Transport (DE-A-3 139 220) ist auf einem Grundwagen ein Querschiebewagen seitlich verschiebbar. Dazu weist der Grundwagen seitlich ausstellbare Ausleger, die auf dem Boden abstützbar sind, auf. Auf diesen Auslegern ist der Querschiebewagen mittels hydraulischer Ein­richtungen ausfahrbar, wozu er mit Laufrädern ausge­rüstet ist, die auf diesen Auslegern abrollen. Abge­sehen davon, daß Grundwagen und Querschiebewagen lediglich für einen innerbetrieblichen Einsatz gebaut sind, ist auch der Ausfahrmechanismus mit seinen Auslegern für den Huckepackverkehr nicht brauchbar. An einem Eisenbahntiefladewagen ist auch eine Querschiebe­einrichtung für eine Tiefladebrücke bekannt (FR-A-2 309 386). Dabei sind die Enden der Ladebrücke über Drehpfannen und Führungswagen auf den Drehgestellen gelagert. Zusätzlich ist die Ladebrücke mit jedem Drehgestell noch über Führungsschiene, Führungslager und Führungszapfen verbunden. Diese bekannte Quer­verschiebeeinrichtung dient zur Erleichterung des Kurvenfahrens mit langen Tiefladewagen und auf Dreh­gestellen gelagerten Ladebrücken. Da diese aufwendige und komplizierte Verschiebeeinrichtung keine seitliche Verschiebung über den Gleisbereich hinaus zuläßt, ist sie zum Zwecke des Beladens neben der Gleisanlage nicht brauchbar.Low-loader wagons of this type which are known in practice for piggyback transport have a low-loader bridge which is supported by a separate support frame mounted on the chassis. Guides are arranged in this support frame, which enable the loading and unloading of the flatbed bridge. A disadvantage of this type of construction is that the wagon is heavy due to the support frame construction and the loading area of the flatbed bridge is higher than that of conventional flatbed wagons. In a track vehicle for in-house transport (DE-A-3 139 220), a transverse sliding carriage can be moved laterally on a basic carriage. For this purpose, the basic carriage has laterally extendable booms that can be supported on the floor. The cross slide carriage can be extended on these arms by means of hydraulic devices, for which purpose it is equipped with running wheels which roll on these arms. In addition to the fact that the base carriage and transverse sliding carriage are only built for internal use, the extension mechanism with its Booms not usable for piggyback traffic. A transverse sliding device for a low-loader bridge is also known on a low-loader railway wagon (FR-A-2 309 386). The ends of the loading bridge are supported on the bogies by means of rotary pans and guide carriages. In addition, the loading bridge is still connected to each bogie via a guide rail, guide bearing and guide pin. This known transverse shifting device serves to facilitate cornering with long flat-bed wagons and loading bridges mounted on bogies. Since this complex and complicated shifting device does not allow any lateral shift beyond the track area, it cannot be used next to the track system for the purpose of loading.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Tiefladewaggon mit seitlich über den Gleisbereich aus­fahrbarer Tiefladebrücke zu schaffen, der sich durch eine besonders leichte Bauweise auszeichnet und leicht aus- und einfahrbar ist.The invention is therefore based on the object of creating a flatbed wagon with a flatbed bridge which can be extended laterally over the track area, which is distinguished by a particularly light construction and is easy to extend and retract.

Diese Aufgabe wird mit einem Tiefladewaggon nach dem Oberbegriff des Patentanspruches 1 erfindungsgemäß durch die Kennzeichnungsmerkmale dieses Patentanspru­ches gelöst.This object is achieved with a flatbed wagon according to the preamble of claim 1 according to the invention by the characterizing features of this claim.

Durch die erfindungsgemäße Bauweise, wonach die Fahr­gestelle des Tiefladewaggons aufgesetzte Führungen auf­weisen, worauf die Tiefladebrücke mit ihren Wannen­trägern seitlich über die Fahrgestelle hinaus verschieb­bar ist, die ausgeschobene Ladebrücke mittels Fahrrollen sich am Perron abstützt und die Fixierung der beiden Fahrgestelle zueinander allein durch die Tiefladebrücke mit ihren Wannenträgern erfolgt, kann diese Tieflade­brücke eine ebenso niedrige Trogladefläche wie übliche nicht ausschiebbare Ladebrücken aufweisen. Da bei dieser Bauart kein zusätzlicher Tragrahmen benötigt wird, ist dieser Tiefladewaggon nicht schwerer als übliche. Der Ein- und Ausschiebevorgang kann entweder mit Seilwinden, Spindeln oder Zylindern erfolgen. Um ein einfaches Ein- bzw. Ausschieben zu ermöglichen, ist es vorteilhaft, entweder die Federung dazu zu blockieren oder die Fahrgestelle abzustützen. Dadurch ist eine konstante Höhe der Oberkanten der Fahrge­stelle gegeben, es kommt zu keinem Verspannen der Führungsmechanismen und es wird unnötiger Kraftaufwand und Verschleiß verhindert. Des weiteren kann ein pneu­matischer oder mechanischer Hubmechanismus für die Führungen auf den Fahrgestellen eingesetzt und somit ein Höhenunterschied zwischen Schienenoberkante und Perron ausgeglichen werden.Due to the design according to the invention, according to which the chassis of the flatbed wagon have attached guides, whereupon the flatbed bridge with its tub supports can be moved laterally beyond the chassis, the extended loading bridge is supported on the platform by means of castors, and the fixing of the two chassis to each other solely by the flatbed bridge with theirs Trough carriers, this low-loading bridge can have a trough loading area that is just as low as conventional loading platforms that cannot be extended. There with no additional support frame is required for this type of construction, this flatbed wagon is not heavier than usual. The push-in and push-out process can be carried out either with winches, spindles or cylinders. In order to make it easy to push in and out, it is advantageous to either block the suspension or to support the chassis. This ensures a constant height of the upper edges of the chassis, there is no tensioning of the guide mechanisms and unnecessary effort and wear is prevented. Furthermore, a pneumatic or mechanical lifting mechanism can be used for the guides on the chassis, thus compensating for a height difference between the top edge of the rail and the platform.

Die Erfindung wird anhand eines Ausführungsbeispiels, das auch in der Zeichnung schematisiert dargestellt ist, näher beschrieben. Es zeigen:

  • Fig. 1 einen Tiefladewaggon in ausge­fahrener und eingeschobener Position,
  • Fig. 2 bis Fig. 5 die Reihenfolge eines Belade­vorganges und
  • Fig. 6 einen Zylinder mit Hakeneinrichtung zum Ausziehen der Tiefladebrücke.
The invention is described in more detail using an exemplary embodiment, which is also shown schematically in the drawing. Show it:
  • 1 is a flatbed wagon in the extended and retracted position,
  • Fig. 2 to Fig. 5 shows the sequence of a loading process and
  • Fig. 6 shows a cylinder with hook device for pulling out the flatbed bridge.

Die Tiefladebrücke 1 wird mit den Winden 2 und 3 von den Fahrgestellen 5 auf den Perron gezogen. Die Fahr­rollen 9 an der Unterseite der Tiefladebrücke 1 stützen diese beim Ein- und Ausfahren am Perron ab und ver­mindern den Kraftaufwand dafür. Die beiden Fahrge­stelle 5 werden lediglich durch die Wannenträger 4 der Tiefladebrücke 1 zueinander fixiert. Die Tiefladebrücke 1 wird durch die Winden 2 von den Fahrgestellen 5 gezogen, wobei sie auf an den Oberseiten der Fahrgestelle 5 an­gebrachten Führungen 10 mittels Rollen 8 läuft. Ein LKW-Zug 6 fährt über die Auffahrrampen 7 auf die Tiefladebrücke 1 auf und diese wird dann durch die Winden 3 wieder eingefahren.The flatbed bridge 1 is pulled with the winches 2 and 3 from the chassis 5 onto the platform. The castors 9 on the underside of the flatbed bridge 1 support them when entering and exiting the platform and reduce the effort required for this. The two chassis 5 are only fixed to each other by the tub support 4 of the flatbed bridge 1. The flatbed bridge 1 is pulled by the winches 2 from the chassis 5, wherein it runs on guides 10 attached to the upper sides of the chassis 5 by means of rollers 8. A truck train 6 drives over the ramps 7 on the Flatbed bridge 1 and this is then retracted by the winches 3.

In Fig. 6 ist ein Zylinder 12 für eine alternative Aus­führung, die zum Ein- und Ausfahren anstelle von Winden Zylinder benützt, dargestellt. Der Zylinder 12 ist gelenkig gelagert. Die teleskopische Kolbenstange 13 hat zwei Rollen 14 an ihrem Ende, um ein leichteres Bedienen zu ermöglichen und Beschädigungen zu vermeiden. Der Hub des Zylinders 12 ist so groß wie die für den Ausziehvorgang benötigte Wegstrecke. Der ebenfalls am Ende der Kolbenstange 13 angebrachte Haken 15 ist schwenkbar und wird von Hand an den an der Tieflade­brücke 1 angebrachten Halterungen 16 eingehängt. Wenn längere Distanzen überbrückt werden sollen, kann am Kolbenstangenende anstelle des Hakens 15 ein Seil mit Haken angebracht werden, oder eine Öse, an der ein Seil mit Haken angebracht ist, im Haken eingehängt werden.6 shows a cylinder 12 for an alternative embodiment which uses cylinders for retracting and extending instead of winches. The cylinder 12 is articulated. The telescopic piston rod 13 has two rollers 14 at its end in order to make operation easier and to avoid damage. The stroke of the cylinder 12 is as large as the distance required for the extraction process. The hook 15, which is also attached to the end of the piston rod 13, can be pivoted and is hung by hand on the brackets 16 attached to the flatbed bridge 1. If longer distances are to be bridged, a rope with a hook can be attached to the end of the piston rod instead of the hook 15, or an eyelet to which a rope with a hook is attached can be hung in the hook.
