Abstract

The arrangement consists of a clearing shield and fixtures, with which the shield is fastened to a carrying frame (1) of the rail vehicle, and which deform at an impact load on the shield, which oversteps a predetermined limit. The fixtures (9, 22, 26, 30) are designed in such way, that the track clearing arrangement (8) is held parallel to the plane of the carrying frame at a deformation of the fixtures through the impact load. A dissipation of the energy of the impact load results through one or several energy dissipation elements (17, 18, 26, 33) arranged at the fixtures.

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 dem Schienenweg 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 Cope with obstacles located on the track. At the brackets with which the road clearer is usual is attached to the support frame of the rail vehicle the risk of collisions with obstacles to which considerable energies are implemented, not only the road sweeper and the brackets deform, but the support frame is also damaged. Furthermore there is Danger of the road clearer either buckling downwards and bores or tears into the track bed and when rolling over through the vehicle wheels the derailment of the rail vehicle caused.

Der Erfindung liegt die Aufgabe zugrunde, einen Fahrbahnräumer der genannten Art so auszugestalten, daß 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.The invention has for its object a road clearer of the type mentioned so that in the event of collisions with considerable energy conversion on the one hand the danger of a Damage to the support frame and secondly the danger derailment by a downward bent or demolished road clearance is reduced.

Die erfindungsgemäße Lösung der Aufgabe ist im Anspruch 1 angegeben. Die Unteransprüche beziehen sich auf vorteilhafte Ausgestaltungen der Erfindung.The achievement of the object is specified in claim 1. The sub-claims relate to advantageous Embodiments of the invention.

  • Fig. 5 die Seitenansicht des Endteils des Tragrahmens mit einer vierten Ausführungsform einer Fahrbahnräumer-Halterung.
    • Four embodiments of the invention are explained in more detail with reference to the drawing. It shows in a schematic representation:
  • 1 is a side view of the end part of the support frame of a rail vehicle with a lane clearer (only left clearing blade shown) and a first embodiment of a lane clearer bracket,
  • 2 shows the side view of the end part of the support frame with a road clearer (only left clearing blade shown) with a second embodiment of a road clearer holder,
  • 3 shows the end part according to FIG. 2 in a view from below,
  • Fig. 4 is a side view of the end part of the support frame with a lane clearer with a third embodiment of a lane clearer bracket and
  • Fig. 5 is a side view of the end part of the support frame with a fourth embodiment of a clearing bracket.

    • Das in Fig. 1 dargestellte Endteil eines Schienenfahrzeugs, beispielsweise einer Lokomotive, besteht aus einem Tragrahmen 1, von dem hier nur das Kopfteil dargestellt ist, an dem die Puffer 2 befestigt sind. Teilweise dargestellt ist ein Drehgestellrahmen 3 mit den auf der Schiene 4 abrollenden Rädern 5 des ersten Radsatzes.The end part of a rail vehicle shown in FIG. 1, for example a locomotive consists of a support frame 1, of which only the head part is shown, on which the Buffers 2 are attached. A bogie frame is partially shown 3 with the wheels rolling on the rail 4 5 of the first wheelset.

    Zwischen den Puffern 2 und dem Drehgestellrahmen 3 ist ein aus zwei Räumschilden 6 und 7 bestehender Fahrbahnräumer 8 mittels einer Halterungsvorrichtung 9 am Tragrahmen 1 befestigt, wobei in Fig. 1 lediglich der linke Räumschild 6 dargestellt ist. Die Räumschilde 6 und 7 sind in allen Ausführungsformen identisch wobei der komplementäre rechte Räumschild 7 nur in Fig. 3 teilweise dargestellt ist.Between the buffers 2 and the bogie frame 3 is a consisting of two clearing blades 6 and 7 attached to the supporting frame 1 by means of a mounting device 9, only the left blade 6 is shown in FIG. 1 is. The clearing blades 6 and 7 are in all embodiments identical with the complementary right blade 7 is only partially shown in FIG. 3.

    Die Halterungsvorrichtung 9 nach Fig. 1 besteht aus einem Räumschildträger 10, der mittels zweier Gelenkhebel 11 und 12 am Kopfstück des Tragrahmens 1 angelenkt ist. Der Räumschildträger 10, die Gelenkhebel 11 und 12 sowie ein Teil des Tragrahmens 1 bilden ein Gelenkviereck mit den Gelenken 13,14,15 und 16. Zwischen den diagonal gegenüberliegenden Gelenken 13 und 15 bzw. 14 und 16 sind auf Zug- und/oder Druckbelastung ansprechende Energieverzehrelemente 17 und 18 angeordnet.1 consists of a Snow blade carrier 10, which by means of two articulated levers 11 and 12 is articulated on the head piece of the support frame 1. The snow blade carrier 10, the articulated lever 11 and 12 and part of the support frame 1 form a quadrilateral joint with the joints 13, 14, 15 and 16. Between the diagonally opposite joints 13 and 15 or 14 and 16 are under tensile and / or compressive load responsive energy consumption elements 17 and 18 arranged.

    Der Räumschildträger 10 weist an seinem vorderen Ende eine Räumschildhalterung auf, an der die vorderen Enden der Räumschilde 6 und 7 befestigt sind. Im hinteren Bereich werden die Räumschilde von einer Quertraverse 20 gehalten, die am hinteren Ende des Räumschildträgers 10 befestigt ist.The dozer blade carrier 10 has one at its front end Dozer blade holder on which the front ends of the dozer blades 6 and 7 are attached. Be in the back the clearing blades held by a crossbar 20, the rear end of the dozer blade holder 10 is attached.

    Im Fall der Kollision des Fahrbahnräumers 8 mit einem Hindernis großer Masse, beispielsweise einem auf dem Schienenweg liegenden Felsbrocken, schwingt der Fahrbahnräumer 8 aufgrund der Gelenkviereckhalterung gleichzeitig nach hinten und nach oben, wobei der Fahrbahnräumer 8 im wesentlichen in einer zum Tragrahmen 1 parallelen Ebene 21 positioniert bleibt. Das Hindernis wird zum einen durch die pflugscharartigen Räumschilde 6 und 7 seitlich weggeschleudert und erhalt durch das Hochschwenken des Fahrbahnräumers 8 gleichzeitig auch einen Anhebeimpuls mit dem die Gefahr gemindert wird, daß das Hindernis unter den Fahrbahnräumer 8 und zwischen die Räder 5 und die Schienen 4 gerät. Durch das im wesentlichen parallel zum Tragrahmen 1 eintretende Anheben des Fahrbahnräumers und der von diesem erfaßten Hindernisse wird somit die Gefahr einer Entgleisung durch zwischen Rad 5 und Schiene 4 gelangende Teile des Fahrbahnräumers 8 und von Hindernissen reduziert. Ferner werden durch die mit der Parallelverschwenkung einhergehende Verformung der Energieverzehrelemente 17, 18 beträchtliche Energien umgesetzt, wodurch eine Beschädigung des Tragrahmens verhindert oder weitgehend gemindert werden kann.In the event of a collision of the road clearer 8 with an obstacle large mass, for example one on the railroad lying boulders, the road clearer 8 swings due to the quadrilateral bracket backwards and forwards at the same time above, the lane scraper 8 essentially in one for Support frame 1 parallel plane 21 remains positioned. The On the one hand, obstacles are created by the ploughshare-like clearing blades 6 and 7 flung sideways and get through that Swiveling the lane scraper 8 up at the same time Lift pulse with which the danger is reduced that the obstacle under the road clearer 8 and between the wheels 5 and the rails 4. By essentially parallel to the support frame 1 entering lifting the road clearer and The obstacles covered by this thus become a danger Derailment caused by between wheel 5 and rail 4 Parts of the road clearer 8 and reduced from obstacles. Furthermore, due to the parallel pivoting Deformation of the energy dissipation elements 17, 18 considerable Energies implemented, causing damage to the Support frame can be prevented or largely reduced.

    Die Figuren 2 und 3 zeigen eine zweite Ausführungsform der Anordnung des Fahrbahnräumers 8 mit zwei Räumschilden 6 und 7, zwei Räumschildträgern 24, einer Räumschildhalterung 19 und einer Quertraverse 20 für den Fahrbahnräumer 8.Figures 2 and 3 show a second embodiment of the Arrangement of the road clearer 8 with two clearing blades 6 and 7, two snow blade carriers 24, a snow blade holder 19 and a crossbar 20 for the road clearer 8.

    Die Halterung 22 besteht aus einer vorderen Tragplatte 23, die mit einem Ende an der Frontplatte des Tragrahmens 1 und mit dem anderen Ende am Räumschildträger 24 befestigt ist, und einer hinteren Tragplatte 25, die im Parallelabstand zur vorderen Tragplatte 23 am Tragrahmen 1 und am Räumschildträger 24 befestigt ist. Am unteren Ende der hinteren Tragplatte 25 ist die Quertraverse 20 befestigt. Am unteren Ende der vorderen Tragplatte 23 sind zwei Räumschildhalterungen 19 angeordnet, an denen jeweils der linke und der rechte Räumschild 6 und 7 angeordnet sind. Zwischen der vorderen und der hinteren Tragplatte 23 und 25 befinden sich zum einen die Räumschildträger 24 und zum anderen die Energieverzehrelemente 26.The bracket 22 consists of a front support plate 23, which with one end on the front plate of the support frame 1 and is attached at the other end to the dozer blade carrier 24, and a rear support plate 25 which is parallel to the front support plate 23 on the support frame 1 and the dozer carrier 24 is attached. At the lower end of the rear support plate 25, the crossbar 20 is attached. At the bottom of the front support plate 23, two dozer blade holders 19 are arranged, on which the left and right dozer blades 6 and 7 are arranged. Between the front and the rear support plate 23 and 25 are the one Snow blade carrier 24 and the other the energy consumption elements 26.

    Die Räumschildträger 24 und die Energieverzehrelemente 26 werden aus zwei kastenartigen Trägern mit rechteckigem Querschnittsprofil gebildet, deren obere, in Fig. 2 schraffiert dargestellte Teilbereiche, die Energieverzehrelemente 26 und deren untere Teilbereiche die Räumschildträger 24 bilden, Die oberen schmalen Flächen 26a und 26b der kastenartigen Träger sind zur vorderen Tragplatte 23 nach unten geneigt. An den mit den Bezugszeichen a, b, c und d gekennzeichneten Stellen befinden sich senkrecht zur Bildebene nach Fig. 2 verlaufende Knickachsen, in denen die Halterung 22 des Fahrbahnräumers 8 im Kollisionsfall mit einem Hindernis einknicken. Das Einknicken an den Knickachsen a, b, c, und d erfolgt ähnlich wie bei dem Gelenkviereck nach der Ausführungsform nach Fig. 1, so daß der Fahrbahnräumer 8 im Kollisionsfall unter Verformung der Energieverzehrelemente 26 im wesentlichen parallel zur Ebene des Tragrahmens 1 nach oben schwenkt.The dozer blade carrier 24 and the energy dissipation elements 26 are made of two box-like beams with a rectangular cross-sectional profile formed, the upper, hatched in Fig. 2 Sub-areas shown, the energy dissipation elements 26 and the lower part of which form the dozer blade carrier 24 upper narrow surfaces 26a and 26b of the box-like carrier are inclined towards the front support plate 23. To the digits marked with the reference symbols a, b, c and d are perpendicular to the image plane according to FIG. 2 Articulated axes in which the bracket 22 of the road clearer 8 buckle with an obstacle in the event of a collision. The buckling at the articulation axes a, b, c, and d is similar to in the four-bar linkage according to the embodiment according to FIG. 1, so that the road clearer 8 is deformed in the event of a collision the energy dissipation elements 26 substantially parallel pivots up to the level of the support frame 1.

    Die in Fig. 4 dargestellte dritte Ausführungsform zeigt einen Fahrbahnräumer 8, dessen beide Räumschilde 6 und 7 von einem Räumschildträger 10, einem Räumschildhalter 19 und einer Quertraverse 20 gehalten sind. Der Fahrbahnräumer 8 ist am Tragrahmen 1 über eine Haltevorrichtung 26 befestigt, die aus einem Gelenkhebel 27 und einer hinteren Tragplatte 28 besteht. Der Gelenkhebel 27 ist in einem oberen Gelenkpunkt 27a am Tragrahmen 1 und in einem unteren Gelenkpunkt 27b am Räumschildträger 10 angelenkt. Die hintere Tragplatte 28 ist am Räumschildträger 10 und am Tragrahmen 1 starr befestigt.The third embodiment shown in FIG. 4 shows one Lane clearer 8, the two clearing blades 6 and 7 of one Dozer blade holder 10, a dozer blade holder 19 and one Crossbar 20 are held. The lane clearer 8 is on Support frame 1 attached via a holding device 26, which from an articulated lever 27 and a rear support plate 28. The articulated lever 27 is in an upper articulation point 27a on the support frame 1 and in a lower hinge point 27b on the dozer blade carrier 10 hinged. The rear support plate 28 is on Dozer 10 and rigidly attached to the support frame 1.

    Im Kollisionsfall wird der Fahrbahnräumer 8 gegenüber dem Tragrahmen 1 nach hinten verschoben und gleichzeitig im wesentlichen parallel zum Tragrahmen 1 hin angehoben. Als Energieverzehrelement dient dabei die durch Biegung sich verformende Tragplatte 28. Die bei der Biegung sich umsetzende Energie kann wahlweise noch durch weitere Energieverzehrelemente 29 vergrößert werden.In the event of a collision, the road clearer 8 is compared to the Support frame 1 moved backwards and at the same time essentially raised parallel to the support frame 1. As an energy consumption element serves the deforming by bending Support plate 28. The energy that is converted during the bend can optionally by additional energy consumption elements 29 can be enlarged.

    Die in Fig. 5 dargestellte vierte Ausführungsform zeigt einen Fahrbahnräumer 8, dessen beide Räumschilde 6 und 7 von einem Räumschildträger 10, einem Räumschildhalter 19 und einer Quertraverse 20 gehalten sind. Der Fahrbahnräumer 8 ist am Tragrahmen 1 mittels einer Halterung 30 befestigt, die aus einem vorderen und einem hinteren, jeweils fest mit dem Tragrahmen 1 verbundenen Lagerbock 31 und 32 besteht. In den Lagerböcken 31 und 32 ist der Räumschildträger 10 axial verschieblich gelagert. Ein Energieverzehrelement 33 ist zwischen dem hinteren Lagerbock 32 und einen fest mit dem Räumschildträger 10 verbundenen Anschlagring 34 angeordnet.The fourth embodiment shown in FIG. 5 shows one Lane clearer 8, the two clearing blades 6 and 7 of one Dozer blade holder 10, a dozer blade holder 19 and one Crossbar 20 are held. The lane clearer 8 is on Support frame 1 attached by means of a bracket 30, which from a front and a rear, each fixed to the support frame 1 connected bearing block 31 and 32. In the bearing blocks 31 and 32 the dozer blade carrier 10 is axially displaceable stored. An energy dissipation element 33 is between the rear bracket 32 and one firmly with the dozer blade carrier 10 connected stop ring 34 arranged.

    Im Fall einer schweren Kollision mit einem Hindernis wird der Fahrbahnräumer 8 nach hinten gedrückt und dabei das Energieverzehrelement 33 verformt. Grundsätzlich können auch die Lagerböcke 31 und 32 so ausgebildet sein, daß sie sich im Kollisionsfall unter Energieumsetzung verformen. In jedem Fall bleibt damit weitgehend sichergestellt, daß im Kollisionsfall mit einem Hindernis weder der Fahrbahnräumer 8 noch Teile davon zwischen Rad und Schiene gelangen und eine Entgleisung des Schienenfahrzeugs hervorrufen.In the event of a serious collision with an obstacle, the Lane clearer 8 pushed back while the energy dissipation element 33 deformed. In principle, the bearing blocks can also 31 and 32 be designed so that they collide deform with energy conversion. In any case remains largely ensured that in the event of a collision with an obstacle neither the clearer 8 nor parts thereof get between wheel and rail and a derailment of the rail vehicle.
