Technisches Gebiet Technical area
Die Erfindung betrifft eine Entsandungseinrichtung für ein Schienenfahrzeug The invention relates to a desanding device for a rail vehicle
Stand der Technik State of the art
Ablagerungen von Sand auf Gleisen können für den Bahnbetrieb hinderlich sein. Insbesondere in Wüstengebieten können Gleise mit Sand verweht sein, was eine aufwendige Entfernung des Sandes erforderlich macht, da zu große Sandmengen auch zu Entgleisungen führen können. Dazu werden Sandräummaschinen eingesetzt, die an Kraftfahrzeugen angeordnet sind und welche den Sand beispielsweise mittels einer Sandfrässchleuder entfernen. Diese Maschinen können auch an der Stirnseite eines Schienenfahrzeugs angeordnet sein, welches die Strecke langsam befährt. Die bekannten Sandräumverfahren weisen jedoch einen Nachteil auf, da sie kleine Sandablagerungen am Schienenkopf nicht zu entfernen vermögen. Diese kleinen Deposits of sand on tracks can be a hindrance to rail operations. Especially in desert areas tracks can be blown up with sand, which makes a complicated removal of the sand necessary, because excessive amounts of sand can also lead to derailments. These sanding machines are used, which are arranged on motor vehicles and which remove the sand, for example by means of a Sandfrässchleuder. These machines can also be arranged on the front side of a rail vehicle, which travels the route slowly. However, the known sanding methods have a disadvantage because they are not able to remove small sand deposits on the rail head. These little ones
Sandablagerungen, welche für die Fahrsicherheit keine Sand deposits, which for driving safety no
Einschränkung darstellen rufen jedoch einen massiv erhöhten Verschleiß an den Schienenfahrzeugrädern hervor. So ist das typische Intervall zwischen zwei Reprofilierungen However, restricting them cause massively increased wear on the rail vehicle wheels. So that's the typical interval between two reprofiling
(Nachbearbeitung des Radprofils) von 150.000km bei Fahrten in Wüstengebieten auf ca. 30.000km reduziert. Besonders (Post-processing of the wheel profile) of 150,000km when driving in desert areas reduced to about 30,000km. Especially
nachteilig ist, dass diese minimalen Sandablagerungen durch Wind kontinuierlich neu geschaffen werden und eine A disadvantage is that these minimal sand deposits are continuously recreated by wind and a
Reinigungsfahrt zur Entfernung dieser minimalen Sandablagerungen mit einer Sandräummaschine sowohl unwirtschaftlich als auch erfolglos wäre. Es liegt nahe, daher die Schienenfahrzeuge selbst mit einer Einrichtung zur Entfernung geringer Sandablagerungen von den Gleisen Cleaning ride to remove this minimum Sand deposits with a sand brooder would be both uneconomical and unsuccessful. It is therefore obvious, therefore, the rolling stock itself with a device for removing small sand deposits from the tracks
auszustatten. Dadurch kann das Problem des kontinuierlich neu auf die Gleise eingebrachten Sandes gelöst werden, da eben das Schienenfahrzeug selbst diese Ablagerungen unmittelbar und während der Fahrt entfernt. Dazu können beispielsweise Bürsten eingesetzt werden, welche vor der führenden Achse angeordnet sind. Eine weitere Möglichkeit der Sandentfernung besteht durch das Ausblasen von im Fahrzeug erzeugter equip. As a result, the problem of continuously introduced new sand on the track can be solved because just the rail vehicle itself removes these deposits immediately and while driving. For this example, brushes can be used, which are arranged in front of the leading axis. Another possibility of sand removal consists of the blowing of generated in the vehicle
Druckluft. Alle diese Verfahren bedingen große Änderungen an dem Fahrzeug und rufen sowohl einen erhöhten Wartungsaufwand als auch einen erhöhten Energieverbrauch hervor. Compressed air. All of these methods cause major changes to the vehicle and cause both increased maintenance and increased energy consumption.

Entsandungseinrichtung für ein Schienenfahrzeug aufgebaut, welche mindestens eine Luftleiteinrichtung mit Desanding device constructed for a rail vehicle, which at least one air guide with
Befestigungsmitteln zur Anordnung der Luftleiteinrichtung an dem Schienenfahrzeug umfasst, wobei die mindestens eine Attachment to the arrangement of the louver the rail vehicle, wherein the at least one
Luftleiteinrichtung so ausgebildet ist, dass die durch die Bewegung des Schienenfahrzeugs hervorgerufene Luftströmung an eine Position unmittelbar vor die Räder einer in Air guiding device is designed so that caused by the movement of the rail vehicle air flow to a position immediately in front of the wheels of a in
Fahrtrichtung führenden Achse des Schienenfahrzeugs geleitet wird . Direction leading axis of the rail vehicle is passed.
Dadurch ist der Vorteil erzielbar, den am Schienenkopf anhaftenden Sand entfernen zu können und ein Zermahlen dieses Sandes durch die Räder des Schienenfahrzeugs verhindern zu können. Solcherart wird der Verschleiß der Räder verringert. Ein weiterer wesentlicher Vorteil der Erfindung liegt darin, dass die Entsandungseinrichtung keinerlei bewegte Teile oder Bürsten aufweist und auch keinerlei Anschlüsse zu As a result, the advantage can be achieved to remove the adhering to the rail head sand and to prevent grinding of this sand through the wheels of the rail vehicle can. Thus wear of wheels is reduced. Another significant advantage of the invention is that the desander has no moving parts or brushes and no connections to
elektrischen oder pneumatischen Systemen des electric or pneumatic systems of the
Schienenfahrzeugs erfordert. Weiters kann eine  Rail vehicle requires. Furthermore, one can
erfindungsgemäße Entsandungseinrichtung bei bestehenden Desanding device according to the invention in existing
Fahrzeugen nachgerüstet werden. Eine bevorzugte Ausführungsform der Erfindung sieht vor, dass die unmittelbar vor die Räder einer in Fahrtrichtung Vehicles to be retrofitted. A preferred embodiment of the invention provides that the directly in front of the wheels in the direction of travel
führenden Achse des Schienenfahrzeugs geleitete Luftströmung eine horizontale Geschwindigkeitskomponente normal zur The air flow directed at the leading axis of the rail vehicle is a horizontal component of normal velocity
Bewegungsrichtung des Schienenfahrzeugs umfasst. Dies wird durch eine Führung des Luftstroms in eine entsprechende Movement direction of the rail vehicle comprises. This is done by guiding the airflow into an appropriate one
Richtung durch die Luftleiteinrichtung gewährleistet. Dabei ist der Winkel der Luftströmung in Bezug auf das Gleis so zu wählen, dass der Sand die Gleisoberfläche verläßt bevor das Rad die betreffende Stelle berührt.  Direction ensured by the louver. In this case, the angle of the air flow with respect to the track is to be selected so that the sand leaves the track surface before the wheel touches the relevant point.
Die Luftleiteinrichtung kann auf mehrere Arten ausgebildet sein, wobei entsprechend einer ersten bevorzugten The spoiler can be designed in several ways, according to a first preferred
Ausführungsform die Luftleiteinrichtung als Rohr ausgebildet ist. Dieses Rohr erstreckt sich von der Stirnseite des Embodiment, the louver formed as a tube is. This tube extends from the front of the
Schienenfahrzeugs bis zu einer Position unmittelbar vor dem führenden Rad. Das dem Rad zugewandten Ende des Rohres kann mit einer den Rohrquerschnitt verengenden Düse ausgestattet sein, wodurch die Ausströmungseigenschaften, insb. der Rail vehicle to a position immediately in front of the leading wheel. The wheel facing the end of the tube may be equipped with a narrowing the tube cross-section nozzle, whereby the outflow characteristics, esp. The
Auftreffpunkt und Auftreffwinkel der Luftströmung auf das Gleis gut vorgebbar sind.  Impact point and impact angle of the air flow on the track are well specified.
Dabei kann es besonders vorteilhaft sein, die  It may be particularly advantageous, the
Luftleiteinrichtung als Rohr mit in Bewegungsrichtung der Luftströmung verkleinerndem Querschnitt auszuführen. Execute air guide device as a tube with decreasing in the direction of movement of the air flow cross-section.
Solcherart kann die pro Zeiteinheit durch die Such can be the per unit time by the
Luftleiteinrichtung geführte Luftmenge gesteigert werden und der Ausblasdruck und somit die Reinigungswirkung erhöht werden .  Air guide guided amount of air to be increased and the blow-off pressure and thus the cleaning effect can be increased.
Eine weitere bevorzugte Ausführungsform der Another preferred embodiment of
Entsandungseinrichtung sieht vor, die Luftleiteinrichtung als Luftleitblech auszuführen. Dazu ist unmittelbar vor dem führenden Rad ein Luftleitblech anzuordnen, welches  Desanding device provides to perform the louver as an air baffle. For this purpose, an air baffle is to be arranged immediately in front of the leading wheel, which
entsprechende Befestigungsmittel für die Befestigung an dem Wagenkasten des Schienenfahrzeugs umfasst. Dieses corresponding fastening means for attachment to the body of the rail vehicle comprises. This
Luftleitblech besteht im einfachsten Fall aus einem zur Air baffle consists in the simplest case of a
Längsachse des Schienenfahrzeugs gewinkelten Blech, welches die Luftströmung vor dem führenden Rad gezielt lenkt, sodass am Schienenkopf haftender Sand von dieser gelenkten Longitudinal axis of the rail vehicle angled sheet, which directs the air flow in front of the leading wheel targeted so that the rail head adhering sand of this
Luftströmung mitgenommen wird und nicht mehr durch das Rad zermahlen wird.  Air flow is taken and not grinded by the wheel.
Das Luftleitblech kann in einfacher Ausführung als  The air baffle can in a simple design as
blechförmiger Bauteil ausgeführt werden, wobei zur optimalen Anpassung der Luftströmung Ausnehmungen (Bohrungen) in das Luftleitblech eingebracht werden können. Diese Bohrungen verändern die Druck- und Strömungsverhältnisse, sodass eine exakte Anpassung an ein konkretes Schienenfahrzeug unter Berücksichtigung der häufigst gefahrenen Geschwindigkeit möglich ist. sheet-shaped component are executed, wherein for optimum adaptation of the air flow recesses (holes) can be introduced into the air guide. These holes change the pressure and flow conditions, so that an exact adaptation to a specific rail vehicle under Consideration of the most frequently driven speed is possible.
Das angeströmte Luftleitblech weist dabei eine Überdruck- und eine Unterdruckseite auf, welche sich aus der Anordnung in einer bewegten Luftmasse ergibt. Es können sowohl der aus der Strömung entstehende Überdruck (von der angeströmten Seite des Luftleitblechs) zur Entsandung eingesetzt werden als auch der Unterdruck an der nichtangeströmten Seite. Zweiteres ist in praktischen Ausführungen der Erfindung vorteilhaft, da dadurch das Luftbleitblech näher der Fahrzeuglängsachse angeordnet werden kann und der Bauraum für das Luftleitblech keinesfalls aus dem Lichtraumprofil des Fahrzeugs ragen darf. Das Luftleitblech kann auch, ähnlich wie die Tragfläche eines Flugzeugs mit einem strömungsgünstigen Profil ausgestattet sein, was eine besonders exakte Leitung der Luftströmung erlaubt, den Bauaufwand für ein Luftleitblech jedoch erhöht.  The streamlined air guide plate has an overpressure and a negative pressure side, which results from the arrangement in a moving air mass. Both the overpressure arising from the flow (from the upstream side of the air guide plate) can be used for desanding and also the negative pressure at the non-flow side. The second is advantageous in practical embodiments of the invention, since thereby the Luftbleitblech can be arranged closer to the vehicle longitudinal axis and the space for the air baffle may under no circumstances protrude from the gauge of the vehicle. The air baffle can also, similar to the wing of an aircraft be equipped with a streamlined profile, which allows a particularly accurate management of the air flow, but increases the construction cost of a baffle.
Eine weitere Ausführungsform der Erfindung sieht vor, A further embodiment of the invention provides

aerodynamischen Eigenschaften auszustatten, welche eine to equip aerodynamic properties, which a
Luftströmung unmittelbar vor die Räder einer in Fahrtrichtung führenden Achse des Schienenfahrzeugs leitet. Dies kann beispielsweise durch entsprechend geformte Unterflurcontainer oder ähnliche Einrichtungen erfolgen. Air flow passes directly in front of the wheels of a leading in the direction of travel axis of the rail vehicle. This can be done for example by appropriately shaped underfloor containers or similar devices.
