Description

Schienenfahrzeug mit Schienenräumer und Schienenräumer für ein Schienenfahrzeug.Rail vehicle with rail clearer and rail cleaner for a rail vehicle.

Die Erfindung betrifft ein Schienenfahrzeug mit einem Schienenräumer sowie einen Schienenräumer für ein Schienenfahrzeug nach den Oberbegriffen der Ansprüche 1 und 8.The invention relates to a rail vehicle with a rail scraper and a rail scraper for a rail vehicle according to the preambles of claims 1 and 8.

Schienenfahrzeuge sind in Fahrtrichtung mit einem Schienenräumer (Bahnräumer) ausgerüstet, um Schäden am Fahrzeug oder Entgleisung durch auf den Schienen oder Gleisen befindlichen Fremdkörper zu verhindern. Schienenräumer (Bahnräumer) sind Vorrichtungen an Schienenfahrzeugen, die vor dem fahrenden Fahrzeug Fremdkörper von den Schienen bzw. vom Gleis beiseiteschieben. Sie werden verwendet, um Entgleisungen sowie auch Schäden am Fahrzeug und beispielsweise an tiefliegenden Achsen der nachfolgenden Fahrzeuge zu verhindern. Häufig werden derartige Schienenräumer für verschiedene Schienenfahrzeuge in einschlägigen Verordnungen auch vorgeschrieben: Danach müssen Fahrzeuge vor dem in Fahrtrichtung ersten Radsatz Bahnräumer oder Schienenräumer haben, die eine durch Hindernisse hervorgerufene Entgleisungsgefahr vermindern. Sie müssen möglichst dicht vor den Rädern angeordnet sein und einen möglichst geringen Abstand von der Schienenoberkante haben.Rail vehicles are equipped in the direction of travel with a rail clearer (track clearer) to prevent damage to the vehicle or derailment due to located on the rails or tracks foreign body. Rail clearers are devices on rail vehicles which push foreign bodies away from the rails or the track in front of the moving vehicle. They are used to prevent derailment as well as damage to the vehicle and, for example, to low-lying axles of the following vehicles. Frequently such rail clearers for various rail vehicles in relevant regulations are also prescribed: Thereafter, vehicles must have before the direction of travel in the first wheel set Bahnräumer or Schienenräumer that reduce a derailment caused by obstacles derailment. They must be arranged as close to the wheels as possible and have the smallest possible distance from the top of the rail.

Bei Fahrzeugen straßenabhängiger Bahnen müssen Bahnräumer oder Schienenräumer auch eine Entgleisungsgefahr vermindern, die durch auf das Gleis gelangende Hindernisse hervorgerufen werden kann. Die Ausführungsarten sind unterschiedlich und meist an die Schienenfahrstrecke und die aus der Umgebung zu erwartenden Störeinflüsse angepasst. In einfachster Ausführung sind dies zwei weit vorn am Triebfahrzeug angebrachte senkrechte Stäbe, die sich dicht über der Schienenoberkante befinden. Derartige Schienenräumer oder Schienenfahrzeuge mit Schienenräumern werden bereits in Druckschriften DE 166 218 A , DE 16 05 830 C3 , DE 883 453 B , AT 515 578 B1 , DE 446 925 A , DE 111 701 A , US 1 285 880 A und DE 10 2013 214 424 B3 beschrieben.In the case of off-road vehicles, wreckers or track-clearers must also reduce the risk of derailment that may be caused by obstacles entering the track. The designs are different and usually adapted to the rail route and the expected from the environment disturbances. In the simplest version, these are two vertical bars attached far ahead of the locomotive, which are located just above the top of the rail. Such Schienenräumer or rail vehicles with Schienenräumern are already in publications DE 166 218 A . DE 16 05 830 C3 . DE 883 453 B . AT 515 578 B1 . DE 446 925 A . DE 111 701 A . US Pat. No. 1,285,880 and DE 10 2013 214 424 B3 described.

Für Personen die am Gleis zu liegen kommen und die Gefahr des Überrollen durch ein Schienenfahrzeug gegeben ist, besteht trotz vorhandener Schienenräumer die Möglichkeit, dass Körperteile über oder unter den Schienenräumer kommen, und vom dahinterliegenden Laufrad erfasst werden.For people who are lying on the track and the risk of rolling over a rail vehicle is given, there is the possibility that body parts come over or under the rail cleaner, and be detected by the underlying wheel despite existing Schienenräumer.

Bei neuen Straßenbahnen wird durch die immer geringere Einstiegshöhe auch der Raum unterhalb der Straßenbahn immer geringer. Für den Einbau eines Fangkorbs oder ähnlicher Abweiser-Mechanismen ist kein Platz vorhanden. Das Problem bei einem Schienenfahrzeug mit Schienenräumer ist, dass der Schienenräumer aus mehreren Gründen nicht auf die Höhe der Schienenoberkante (SOK) eingestellt werden kann, und somit immer ein gewisser Spalt zwischen Boden und der Unterkante des Schienenräumers vorhanden ist. Dadurch besteht immer die Möglichkeit, dass bei einem Unfall der Schienenräumer die Person oder den Gegenstand zwar in Fahrtrichtung wegschieben oder wegschleifen kann, Körperteile oder Teile des Gegenstandes jedoch unter- oder auch oberhalb des Schienenräumers durchgleiten können und von einem Schienenrad erfasst/überrollt werden, wodurch es im Fall von Gegenständen auch zu Entgleisungen kommen kann.With new trams is the lower entrance height and the space below the tram ever smaller. There is no space for the installation of a grass catcher or similar deflector mechanisms. The problem with a rail vehicle with a rail cleaner is that the rail cleaner does not rise in height for several reasons the rail top edge (SOK) can be adjusted, and thus there is always a certain gap between the bottom and the lower edge of the rail cleaner. As a result, there is always the possibility that in the event of an accident, the rail cleaner may push or pull away the person or the object in the direction of travel, but body parts or parts of the object may slide below or above the rail cleaner and be caught / rolled over by a rail wheel it can also lead to derailment in the case of objects.

Die Aufgabe der vorliegenden Erfindung besteht deshalb darin die vorgenannten Nachteile weitestgehend zu vermeiden. Erfindungsgemäß wird diese Aufgabe durch die Merkmale der Ansprüche 1 und 6 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den jeweils zugehörigen Ansprüchen enthalten.The object of the present invention is therefore to avoid the aforementioned disadvantages as far as possible. According to the invention this object is solved by the features of claims 1 and 6. Advantageous developments of the invention are contained in the respective claims.

Danach wird ein Schienenfahrzeug mit wenigstens einem Schienenräumer, der vor dem in Fahrtrichtung ersten Radsatz des Schienenfahrzeuges am Drehgestellrahmen angeordnet ist und einen Schienenräumer -Balken umfasst vorgeschlagen, wobei am Schienenräumer - Balken mindestens zwei vertikal bewegbare (aus- und einfahrbare) Schienenräumer-Kolben angeordnet sind. Die Schienenräumer-Kolben werden dabei durch ein die Kolben umschließendes Führungsrohr geführt und gestützt.Thereafter, a rail vehicle with at least one rail scraper, which is arranged in front of the direction of travel in the first wheel of the rail vehicle on the bogie frame and a rail scraper beam is proposed, wherein at Schienenräumer - bar at least two vertically movable (extendable and retractable) rail scraper pistons are arranged , The rail cleaner pistons are guided and supported by a guide tube surrounding the piston.

Die Führungsrohre mit den darin angeordneten Schienenräumer-Kolben sind jeweils unmittelbar vor den Schienenlaufrädern des ersten Radsatzes des Schienenfahrzeuges angeordnet. Die Schienenräumer-Kolben reichen im aktivierten/ausgefahrenen Zustand bis zur Schienenoberkante und verhindern somit jegliches Überrollen. Vorteilhaft sind die Schienenräumer-Kolben mit den Magnetschienenbremsen des Schienenfahrzeuges aktivierbar.The guide tubes with the rail scraper pistons arranged therein are respectively arranged directly in front of the rail wheels of the first wheel set of the rail vehicle. In the activated / extended state, the rail cleaner pistons reach up to the upper edge of the rail and thus prevent any rolling over. Advantageously, the rail cleaner pistons can be activated with the magnetic rail brakes of the rail vehicle.

Die Schienenräumer-Kolben, welche zusätzlich am vorhandenen Schienenräumer lotrecht angeordnet sind, befinden sich in eingezogener Stellung in Höhe Unterkante des Schienenräumer-Balkens. Unebenheiten der Straße, unterschiedliches Niveau von Schienen und Weichen, Senkungen des Wagenkastens durch Abrieb der Laufräder oder durch volle Beladung, konkave oder konvexe Gleisführung, kleinere Steine und Geröll, Schneematsch o.ä. haben dadurch keinen Einfluss auf die Funktion des Schienenräumers.The rail cleaner pistons, which are additionally arranged vertically on the existing rail scraper, are in the retracted position at the level of the lower edge of the rail scraper beam. Unevenness of the road, different levels of rails and switches, lowering of the car body by abrasion of the wheels or by full load, concave or convex track guide, smaller stones and scree, slush or the like. have no influence on the function of the rail scraper.

Zur Erfindung gehört auch ein Schienenräumer, wobei zur Vermeidung von Wiederholungen auf die obigen Ausführungen verwiesen wird, aus welchen sich auch die Merkmale und vorteilhaften Ausgestaltungen des Schienenräumers entnehmen lassen.The invention also includes a Schienenräumer, reference being made to avoid repetition of the above statements, from which can be seen also the features and advantageous embodiments of the rail scraper.

Zur weiteren Erläuterung der Erfindung wird im nachfolgenden Teil der Beschreibung auf die Zeichnungen Bezug genommen, aus welchen weitere vorteilhafte Ausgestaltungen der Erfindung , Einzelheiten und Weiterbildungen anhand nicht einschränkender Ausführungsbeispiele zu entnehmen sind.To further explain the invention, reference is made in the following part of the description to the drawings, from which further advantageous embodiments of the invention, details and developments are based on non-limiting embodiments can be found.

In den Figuren ist das Schienenfahrzeug 10 nur in stilisierter Form durch Darstellung des ersten Radsatzes 11 sowie der Schienenlaufräder 12, 12' zu erkennen. Der Schienenräumer 20 ist vor dem in Fahrtrichtung ersten Radsatz 11 des Schienenfahrzeuges 10 am Drehgestellrahmen des Schienenfahrzeuges 10 angeordnet ist und umfasst einen Schienenräumer -Balken 21 in bekannter Ausführung. Am Schienenräumer - Balken 21 sind zwei vertikal bewegbare (aus- und einfahrbare) Schienenräumer-Kolben 22, 22' direkt vor den Schienenlaufrädern 12, 12' angeordnet. Die Schienenräumer-Kolben 22, 22' werden durch ein die Kolben umschließendes Führungsrohr 23, 23' geführt und gestützt. Im eingefahren Zustand reichen diese nicht über die Unterkante des Schienenräumer -Balkens 21 hinaus. Die Schienenräumer-Kolben 22, 22 sind dabei jeweils unmittelbar vor den Schienenlaufrädern 12, 12' des ersten Radsatzes 11 des Schienenfahrzeuges 10 angeordnet. Die Schienenräumer-Kolben 22, 22' sind mit den Magnetschienenbremsen des Schienenfahrzeuges 10 aktivierbar. Das Aus- und wieder Einfahren der Kolben kann durch verschiedene Mittel erreicht werden wie z. B. elektrisch (Solenoid; e-Motor; Stellmotor) oder mechanisch (hydraulisch, pneumatisch). Dabei sind die Schienenräumer-Kolben 22, 22' bis zur Berührung der Schienenoberkante des Fahrweges eines Schienenfahrzeuges 10 ausfahrbar. Die Kolben sind bezüglich ihrer Breite und/oder ihres Durchmessers so ausgebildet, dass sie der Aufprallgeschwindigkeit einer verunfallten Person entsprechend standhalten. Die Breite oder der Durchmesser der Schienenräumer-Kolben 22, 22' entspricht dabei z.B. mindestens der Breite der Schienenlaufräder 12, 12'. Eine weitere vorteilhafte Ausgestaltung der Schienenräumer-Kolben berücksichtigt die Breite der Schienenlaufräder sowie die Kontaktfläche mit der Schienenoberkante, wobei der Druck auf die Schienenoberkante sehr gering sein kann, aber die Ausfahrgeschwindigkeit der Kolben sehr hoch.In the figures, the rail vehicle 10 can be seen only in stylized form by representation of the first wheel 11 and the rail wheels 12, 12 '. The rail cleaner 20 is disposed in front of the first wheelset 11 of the rail vehicle 10 in the direction of travel on the bogie frame of the rail vehicle 10 and includes a rail scraper bar 21 in a known design. On the rail scraper bar 21, two vertically movable (extendable and retractable) rail scraper pistons 22, 22 'are arranged directly in front of the rail wheels 12, 12'. The rail scraper pistons 22, 22 'are guided and supported by a guide tube 23, 23' enclosing the pistons. In the retracted state, these do not extend beyond the lower edge of the rail scraper bar 21. The rail scraper pistons 22, 22 are in each case arranged directly in front of the rail wheels 12, 12 'of the first wheel set 11 of the rail vehicle 10. The Schienenräumer pistons 22, 22 'are connected to the magnetic rail brakes of Rail vehicle 10 can be activated. The extension and retraction of the piston can be achieved by various means such. Electric (solenoid, e motor, servomotor) or mechanical (hydraulic, pneumatic). Here are the Schienenräumer pistons 22, 22 'extendable to the contact of the upper rail edge of the track of a rail vehicle 10. The pistons are designed with respect to their width and / or their diameter so that they withstand the impact speed of an injured person accordingly. The width or the diameter of the rail scraper piston 22, 22 'corresponds, for example, at least the width of the rail wheels 12, 12'. A further advantageous embodiment of the rail cleaner piston takes into account the width of the rail wheels and the contact surface with the top rail, the pressure on the top rail can be very low, but the extension speed of the piston very high.

Bei Erkennung einer Gefahr durch einen Schienenfahrzeugführer und Einleitung einer Gefahren-/Notbremsung werden parallel mit den Magnetschienenbremsen auch die Schienenräumer-Kolben aktiviert, wobei der Kolben mit ähnlich hoher Geschwindigkeit wie die Magnetschienenbremsen die Schienen erreichen, und lotrecht nach unten bis zur Berührung der Schienenoberkante ausgefahren werden. Nach dem das Fahrzeug zum Stillstand kommt und die Magnetschienenbremsen wieder lösen, werden auch gleichzeitig die Kolben wieder eingezogen. Das Aus- und wieder Einfahren der Kolben kann durch verschiedene Mittel erreicht werden wie z. B. elektrisch (Solenoid; e-Motor; Stellmotor) oder mechanisch (hydraulisch, pneumatisch). Das Schienenräumer-Kolben System lässt sich auch deaktivieren, um im Fall eines großen Hindernisses auf den Gleisen das Fahrzeug nicht zusätzlich zu gefährden (Aufklettern und Entgleisen durch den Wiederstand der Kolben in der ausgefahrenen Stellung), bzw. den Schaden möglichst gering zu halten. Auch sollte die mechanische Schubkraft von wegzuschiebenden Gegenständen in Fahrtrichtung durch die entsprechend stabile Konstruktion der Kolben vorhanden sein. Die Kolben und das sie umgebende Führungsrohr weisen deshalb eine entsprechende Festigkeit auf um die vorgesehene Schutzwirkung gegenüber Personen oder Gegenständen zu erfüllen.Upon detection of a danger by a railway driver and the initiation of a danger / emergency braking, the rail cleaner pistons are activated in parallel with the magnetic rail brakes, the piston reaching the rails at a speed similar to that of the magnetic rail brakes, and extended vertically down to the contact of the rail top edge become. After the vehicle comes to a standstill and the magnetic rail brakes release again, the pistons are retracted at the same time. The extension and retraction of the piston can be achieved by various means such. Electric (solenoid, e motor, servomotor) or mechanical (hydraulic, pneumatic). The rail cleaner-piston system can also be deactivated so as not to endanger the vehicle in the event of a major obstacle on the tracks (climbing and derailing due to the resistance of the pistons in the extended position), or to minimize the damage. Also, the mechanical thrust of wegzuschiebenden objects in the direction of travel should be present by the correspondingly stable construction of the piston. The pistons and the surrounding guide tube therefore have a corresponding strength to meet the intended protection against persons or objects.
