Description

Die Erfindung bezieht sich auf einen Fahrbahnräumer für ein Schienenfahrzeug, gemäß Oberbegriff des Patentanspruchs 1 .The invention relates to a road clearer for a Rail vehicle, according to the preamble of claim 1.

Es ist bekannt, Schienenfahrzeuge, insbesondere Lokomotiven, mit Fahrbahnräumern auszurüsten, die ständig mit dem Tragrahmen des Fahrzeugs verbunden sind und nicht nur das Wegräumen von Schnee sondern auch den Schutz bei Kollision mit auf den Schienen befindlichen Hindernissen bewerkstelligen. Bei den bislang üblichen Halterungen mit denen der Fahrbahnräumer am Tragrahmen des Schienenfahrzeugs befestigt ist, besteht die Gefahr, daß bei Kollisionen mit Hindernissen, bei denen erhebliche Energien umgesetzt werden, sich nicht nur der Fahrbahnräumer und die Halterungen verformen, sondern auch der Tragrahmen beschädigt wird. Im weiteren besteht die Gefahr, daß der Fahrbahnräumer entweder nach unten ausknickt und sich ins Gleisbett bohrt oder abreißt und beim Überrollen durch die Fahrzeugräder die Entgleisung des Schienenfahrzeugs verursacht.It is known to use rail vehicles, especially locomotives, Equip with road clearers that are constantly with the support frame of the vehicle and not just clearing away of snow but also protection in the event of a collision with the Do obstacles on rails. Both Previously usual brackets with those of the road clearers on Carrier frame of the rail vehicle is attached, there is Danger of collisions with obstacles where considerable Energies are implemented, not just the road clearer and deform the brackets, but also the Carrier frame is damaged. Furthermore, there is a risk that the lane clearer either bends down and drilled or torn into the track bed and through when rolling over the vehicle wheels caused the derailment of the rail vehicle.

Bei Fahrbahnräumern, die sich über die gesamte Breite des Schienenwegs erstrecken, besteht zum anderen das Problem, daß bei dessen Befestigung über die Breite des Tragrahmens bzw. des Kopfstückes mehrere weit auseinanderliegende Befestigungspunkte vorzusehen sind, die eine sehr hohe Fertigungsgenauigkeit und einem hohen Aufwand beim Einbau erfordern.For road clearers that span the entire width of the On the other hand, there is the problem that when it is fastened across the width of the supporting frame or of the head piece several widely spaced attachment points are to be provided which have a very high manufacturing accuracy and require a lot of effort during installation.

Der Erfindung liegt daher die Aufgabe zugrunde, einen einfach herzustellenden und zu montierenden Fahrbahnräumer zu schaffen, bei dem bei Kollisionen mit beträchtlicher Energieumsetzung zum einen die Gefahr einer Beschädigung des Tragrahmens und zum anderen die Gefahr einer Entgleisung durch einen nach unten weggebogenen oder abgerissenen Fahrbahnräumer gemindert wird. Die erfindungsgemäße Lösung ist im Anspruch 1 angegeben. Die Unteransprüche beziehen sich auf vorteilhafte Ausgestaltungen der Erfindung.The invention is therefore based on the object, a simple to create and assemble road clearers, in the case of collisions with considerable energy conversion firstly, the risk of damage to the support frame and on the other hand the risk of derailment by one diminished or demolished road clearer below becomes. The solution according to the invention is specified in claim 1. The Subclaims relate to advantageous configurations the invention.

Bei der erfindungsgemäßen Anordnung der Halterung des Fahrbahnräumers am Tragrahmen bzw. dem Kopfträger sind aufgrund der auf den Mittenbereich konzentrierten Tragstruktur nur wenige Befestigungspunkte erforderlich, die zudem aufgrund ihres geringen Abstandes mit verhältnismäßig geringem Herstellungsaufwand mit engen Abstandstoleranzen gefertigt werden können. In entsprechender Weise vereinfacht sich dadurch auch die Montage des Fahrbahnräumers am Tragrahmen.In the inventive arrangement of the bracket of the lane clearer on the support frame or the head support are due only a few of the supporting structures concentrated in the central area Attachment points required, which due to their short distance with relatively little manufacturing effort be manufactured with narrow spacing tolerances can. In a corresponding manner, this also simplifies it the assembly of the lane clearer on the support frame.

Das in Fig. 1 und 2 dargestellte Frontteil einer Lokomotive besteht aus einem Tragrahmen 1, von dem hier nur das Kopfteil dargestellt ist, auf dem das Lokomotivgehäuse 2 abgestutzt ist und an dem die Puffer 3 befestigt sind. Teilweise dargestellt ist ein Drehgestellrahmen 4 mit den auf der Schiene 5 abrollenden Rädern 6 des ersten Radsatzes der Lokomotive.The front part of a locomotive shown in FIGS. 1 and 2 consists of a support frame 1, of which only the head part is shown on which the locomotive housing 2 is supported and to which the buffers 3 are attached. Partially shown is a bogie frame 4 with the on the rail 5th rolling wheels 6 of the first wheelset of the locomotive.

An der Unterseite des Tragrahmens 1 Ist mit Hilfe einer Halterung ein aus zwei Räumschilden 7,8 bestehender Fahrbahnräumer befestigt.At the bottom of the support frame 1 is using a bracket a road clearer consisting of two clearing blades 7,8 attached.

Die Halterung besteht aus einer im wesentlichen kreisrunden oberen Platte 9, die mit einer aus einem hohlen Kreiszylinder 10 bestehenden Tragstruktur verschweißt ist. Die Leitkurve des Kreiszylinders 10 ist geschlossen, so daß dieser ein torsionssteifes System darstellt. Auf der Unterseite des Kreiszylinders 10 ist eine untere Platte 11 angeschweißt, die im vorderen Bereich zwei senkrecht stehende Haltelaschen 12 und 13 aufweist. Im hinteren Bereich ist mit der unteren Platte 11 ein Querträger 14 verschweißt.The bracket consists of an essentially circular top plate 9, which is made of a hollow circular cylinder 10 existing support structure is welded. The main curve of the circular cylinder 10 is closed, so that it is torsionally rigid Represents system. On the bottom of the circular cylinder 10, a lower plate 11 is welded, which in front area two vertical holding tabs 12 and 13 has. In the back is with the lower plate 11 a cross member 14 welded.

Die Räumschilde 7 und 8 sind vorne über angeschweißte Halteplatten 15 und 16 mit den Haltelaschen 12 und 13 verschraubt, wobei über in den Halteplatten 15 und 16 ausgebildete senkrecht stehende Langlöcher eine Höhenverstellung möglich ist. Die hinteren Enden der Räumschilde 7 und 8 sind an den Enden des Querträgers 14 angeschraubt, wobei auch hier eine Höhenverstellbarkeit (nicht dargestellt) vorgesehen ist, so daß der Abstand des Fahrbahnräumers zur Schienenoberkante 17 entsprechend dem Radverschleiß der Lokomotive nachjustiert werden kann.The clearing blades 7 and 8 are at the front via welded-on holding plates 15 and 16 screwed to the retaining tabs 12 and 13, being formed perpendicularly in the holding plates 15 and 16 vertical slots a height adjustment is possible. The rear ends of the clearing blades 7 and 8 are at the ends of the cross member 14 screwed, here also a height adjustability (not shown) is provided so that the distance of the lane clearer to the top edge of the rail 17 accordingly readjusted the wheel wear of the locomotive can.

Die obere Platte 9 ist mit dem Tragrahmen 1 verschraubt.The upper plate 9 is screwed to the support frame 1.

Im Fall einer Kollision des Fahrbahnräumers mit einem Hindernis großer Masse, beispielsweise einem auf dem Schienenweg liegenden Felsbrocken, wird die Kollisionsenergie von der nur im mittleren Bereich des Tragrahmens 1 befestigten Tragstruktur aufgenommen und setzt aufgrund ihrer hohen Torsionsfestigkeit einem Ausschwenken der Räumschilde 7 und 8 einen hohen Widerstand entgegen, auch wenn einer der beiden Räumschilde weit außerhalb der Mitte getroffen werden sollte. Bei extrem starker Kollisionsenergie wird sich die Tragstruktur unter starker Energieabsorbtion so verformen, daß die untere Platte 11 zusammen mit den Räumschilden 7 und 8 im wesentlichen parallel zur oberen Platte 9 nach oben schwenkt. Damit ist weitestgehend sicher gestellt, daß sich die Räumschilde und deren Halterungsteile bei extremer Stoßbelastung nicht in den Gleiskörper bohren oder unter die Räder gelangen und eine Entgleisung der Lokomotive verursachen.In the event of a collision between the clearer and an obstacle large mass, for example one on the railroad lying boulders, the collision energy from the only in the central area of the support frame 1 attached support structure recorded and sets due to their high torsional strength a swiveling the clearing blades 7 and 8 a high Opposing resistance, even if one of the two dozer blades should be hit far out of the middle. At extremely strong collision energy will support the structure deform under strong energy absorption so that the lower Plate 11 together with the blades 7 and 8 essentially pivots upwards parallel to the upper plate 9. In order to is largely ensured that the clearing blades and their mounting parts not in extreme shock loads drill the track or get under the wheels and one Causing the locomotive to derail.
