Description

Die Erfindung betrifft ein Schienenfahrzeug mit einer Schutzeinrichtung sowie eine Schutzeinrichtung für ein Schienenfahrzeug nach den Oberbegriffen der Ansprüche 1 und 9.The invention relates to a rail vehicle with a protective device and a protective device for a rail vehicle according to the preambles of claims 1 and 9.

Schienenfahrzeuge sind in der Regel in Fahrtrichtung mit einem Schienenräumer (Bahnräumer) oder anderen Schutzeinrichtungen (body catcher) 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.Rolling stock is usually equipped in the direction of travel with a track clearer or other body-catcher to prevent damage to the vehicle or derailment of foreign objects on the tracks or tracks. 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.

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. Sie können entweder möglichst weit vorne an der Unterseite des Fahrzeugvorbaus oder am Drehgestell direkt vor den Rädern angeordnet sein und sollten einen möglichst geringen Abstand von der Schienenoberkante haben.According to this, vehicles must have wagons or rail clearers in front of the first wheelset in the direction of travel, which reduce the danger of derailment caused by obstacles. They must be arranged as close to the wheels as possible and have the smallest possible distance from the top of the rail. They can either be arranged as far ahead on the underside of the vehicle stem or on the bogie directly in front of the wheels and should 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 , DE111 701 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 . DE111701A 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.
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. Außerdem ist deren Aufbau und Wartung sehr aufwändig, wobei die geringen Auslösegeschwindigkeiten dieser mechanischen Systeme auch keinen zuverlässigen Schutz vor schweren Verletzungen bieten.For people on the track and the danger
is given by rolling over a rail vehicle, there is the possibility that body parts above or below the Rail scrapers come, and be detected by the underlying impeller.
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. In addition, their construction and maintenance is very complex, the low triggering speeds of these mechanical systems also provide no reliable protection against serious injury.

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. Für Personen, welche am Gleis zu liegen kommen, besteht die Gefahr durch den verbleibenden Spalt (200 - 50 mm) vor Erreichen des Bahnräumers schwere Verletzungen zu erleiden.The problem with a rail vehicle with rail cleaner is that the rail cleaner can not be adjusted to the height of the upper rail edge (SOK) for several reasons, and thus there is always a certain gap between the floor and the lower edge of the rail cleaner. For persons, who come to lie on the track, there is the danger by the remaining gap (200 - 50 mm) before reaching the Bahnräumers to suffer severe injuries.

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 9 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 9. Advantageous developments of the invention are contained in the respective claims.

Danach wird ein Schienenfahrzeug mit einer Frontschürze und mit wenigstens einem Schienenräumer, der vor dem in Fahrtrichtung ersten Radsatz des Schienenfahrzeuges am Drehgestellrahmen angeordnet ist, vorgeschlagen, wobei zusätzlich zum Schienenräumer eine weitere Schutzeinrichtung vorgesehen ist, die vertikal oder im Winkel bewegbare (ein-und ausfahrbar) Schienenräumer-Kolben umfasst, die am Schienenräumer direkt vor dem ersten Radsatz und/oder entlang der dem Fahrweg zugewandten unteren Kontur der Frontschürze unterhalb des Wagenkastens des Schienenfahrzeugs angeordnet sind. Die Schienenräumer-Kolben der Schutzeinrichtung werden dabei durch ein die Kolben umschließendes Führungsrohr geführt und gestützt. Die Führungsrohre mit den darin angeordneten Schienenräumer-Kolben sind jeweils unmittelbar vor den Schienenlaufrädern des ersten Radsatzes des Schienenfahrzeuges angeordnet und reichen im aktivierten/ausgefahrenen Zustand bis zur Schienenoberkante und verhindern somit jegliches Überrollen. Vorteilhaft ist die Schutzeinrichtung mit den Schienenräumer-Kolben mittels der Magnetschienenbremsen des Schienenfahrzeuges aktivierbar. Die Schienenräumer-Kolben der Schutzeinrichtung, welche zusätzlich zum vorhandenen Schienenräumer lotrecht oder schräg im Winkel in oder entgegen der Fahrtrichtung angeordnet sind, befinden sich versenkt in ihren Führungen, damit das Kolbensystem vor Beanspruchungen aus der Umgebung (Schmutz, Nässe und Streusalz) bestmöglich geschützt wird. 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.Thereafter, a rail vehicle with a front apron and with at least one rail cleaner, which is arranged in front of the first wheelset in the direction of travel of the rail vehicle on the bogie frame, proposed, in addition to the Schienenräumer another protective device is provided, the vertically or at an angle movable (retractable and extendable ) Comprises rail cleaner piston, which are arranged on the rail cleaner immediately before the first wheel and / or along the lower contour of the front apron facing the track below the car body of the rail vehicle. The rail cleaner pistons of the protective device are guided and supported by a guide tube surrounding the piston. The guide tubes with the therein arranged Schienenräumer pistons are respectively arranged immediately in front of the rail wheels of the first gearset of the rail vehicle and extend in the activated / extended state up to the rail upper edge and thus prevent any rollover. Advantageously, the protective device can be activated with the rail cleaner piston by means of the magnetic rail brakes of the rail vehicle. The rail cleaner pistons of the protective device, which are arranged in addition to the existing Schienenräumer perpendicular or oblique angle in or against the direction of travel, are sunk in their guides so that the piston system from stresses from the environment (dirt, moisture and road salt) best possible is protected. 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.

In den Figuren ist das Schienenfahrzeug 10 nur in stilisierter Form durch Darstellung des ersten Radsatzes 13 sowie der Schienenlaufräder 12, 12' zu erkennen. Der Schienenräumer 20 ist vor dem in Fahrtrichtung ersten Radsatz 13 des Schienenfahrzeuges 10 am Drehgestellrahmen des Schienenfahrzeuges angeordnet und umfasst einen Schienenräumer - Balken 21 in bekannter Ausführung. Zusätzlich zum Schienenräumer 20 ist eine Schutzvorrichtung 30 vorgesehen, die vertikal bewegbare (aus- und einfahrbare) Schienenräumer-Kolben 31n umfasst, die entlang der dem Fahrweg zugewandten unteren Kontur der Frontschürze 11 des Schienenfahrzeugs 10 angeordnet sind. Die Schienenräumer-Kolben 31n der Schutzeinrichtung 30 sind beginnend direkt vor den Schienenlaufrädern 12, 12' des Schienenfahrzeuges 10 angeordnet und verlaufen entlang der unteren Kontur der Frontschürze des Schienenfahrzeuges in aufgrund auftretender Gegebenheiten am Fahrzeug optimierten Abständen. Die Schienenräumer-Kolben 31n werden jeweils durch ein die Kolben umschließendes Führungsrohr 32 geführt und gestützt. Im eingefahren Zustand reichen diese nicht unter die Unterkante des Schienenräumer - Balkens 21 des Schienenräumers 20 hinaus. Die Schienenräumer-Kolben 31n sind mittels der 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 31n bis zur Berührung der Schienenoberkante des Fahrweges des Schienenfahrzeuges 10 ausfahrbar.In the figures, the rail vehicle 10 can be seen only in stylized form by representation of the first wheel 13 and the rail wheels 12, 12 '. The rail scraper 20 is disposed in front of the first wheelset 13 of the rail vehicle 10 in the direction of travel on the bogie frame of the rail vehicle and comprises a rail scraper - beam 21 in a known design. In addition to the rail scraper 20 a protective device 30 is provided, the vertically movable (extendable and retractable) Rail scraper piston 31n which are arranged along the lower contour of the front apron 11 of the rail vehicle 10 facing the travel path. The rail scraper pistons 31n of the protective device 30 are arranged directly in front of the rail wheels 12, 12 'of the rail vehicle 10 and run along the lower contour of the front apron of the rail vehicle in optimized conditions due to conditions on the vehicle. The rail scraper pistons 31n are each guided and supported by a guide tube 32 enclosing the pistons. In the retracted state, these do not extend below the lower edge of the rail scraper bar 21 of the rail scraper 20. The rail scraper pistons 31n can be activated by means of the magnetic rail brakes of the rail vehicle 10. 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 scraper pistons 31n can be extended until the rail top edge of the track of the rail vehicle 10 is touched.

Vorteilhaft sind die Schienenräumer-Kolben 31n zumindest teilweise mit verschleißfesten Materialien, insbesondere mit UV stabilisierten Polymeren aus PE oder PTFE versehen. Bei Erkennung einer Gefahr durch einen Schienenfahrzeugführer und Einleitung einer Gefahren-/Notbremsung werden parallel mit den Magnetschienenbremsen auch die Schienenräumer-Kolben entlang der Frontschürze aktiviert, wobei der Kolben mit ähnlich hoher Geschwindigkeit wie die Magnetschienenbremsen die Schienen erreichen und z.B. lotrecht nach unten bis zur Berührung der Schienenoberkante ausgefahren werden. Die Schienenräumer-Kolben 31n können nach einer weiteren Variante der Erfindung auch als schräg nach vorne oder nach hinten ausfahrbare Kolben ausgeführt sein und durch Führungsrohre gestützt werden. Die Hublänge der übrigen Kolben wird vorzugsweise durch die Hublänge der Kolben direkt vor dem ersten Radsatz vorgegeben, wobei in einer weiteren Ausführungsvariante die Hublänge dieser übrigen Kolben an die vertikale Streckengeometrie (Kuppe, Wanne) mittels Abstandsmesssensoren oder über GPS Erkennung angepasst werden kann. Während des kritischen Zeitpunkts besteht somit keine Möglichkeit mehr, dass Personen unter die Vorbaukontur (Frontschürze 9) des Schienenfahrzeuges gelangen können, da dir Kontur entlang der Frontschürze bis vor den führenden ersten Radsatz abgedeckt wird. 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).The rail scraper pistons 31n are advantageously at least partially provided with wear-resistant materials, in particular UV-stabilized polymers made of PE or PTFE. Upon detection of a hazard by a rail operator and initiation of hazard / emergency braking, the rail cleaner pistons along the front apron are activated in parallel with the magnetic rail brakes, the pistons reaching the rails at a speed similar to that of the magnetic rail brakes, e.g. be extended vertically down to the touch of the top rail. According to a further variant of the invention, the rail scraper pistons 31n can also be designed as pistons which can be extended obliquely forwards or rearwards and are supported by guide tubes. The stroke length of the remaining pistons is preferably predetermined by the stroke length of the pistons directly in front of the first wheel set, wherein in a further embodiment, the stroke length of these other pistons can be adapted to the vertical path geometry (dome, trough) by means of distance measurement sensors or via GPS detection. During the critical time there is thus no possibility that persons can get under the stem contour (front apron 9) of the rail vehicle, since you contour is covered along the front apron until the leading first wheelset. 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).
