Description

Die Erfindung betrifft einen Führertisch zum Aufstellen in einem Führerstand eines schienengebundenen Fahrzeuges mit einer Führertischabdeckung, die über eine Lufteintrittsöffnung und über eine Luftaustrittsöffnung verfügt und mit einer raumlufttechnischen Anlage, die im Betrieb von der Führertischabdeckung verdeckt ist und eine Ansaugöffnung sowie eine Abblasöffnung aufweist.The invention relates to a driver's desk for installation in a driver's cab of a rail vehicle with a guide table cover, which has an air inlet opening and an air outlet opening and with a ventilation system, which is covered during operation of the guide table cover and having a suction port and a blow-off.

Ein solcher Führertisch ist aus dem landläufigen Stand der Technik bereits bekannt und beispielsweise in Figur 1 in einer geschnittenen Seitenansicht verdeutlicht. Der vorbekannte Führertisch 1 ist an der Frontseite unterhalb der Windschutzscheibe in dem Führerstand 2 eines schienengebundenen Fahrzeuges angeordnet. Eine Führertischabdeckung 3 dient zum Halten von teilweise empfindlichen Geräten und Komponenten 4, wie beispielsweise Bildschirmen, Steckverbindungen, Steuerungshebeln oder der gleichen. Der Führertisch 1 umfasst ferner eine unter der Führertischabdeckung 3 angeordnete raumlufttechnische Anlage 5. Die raumlufttechnische Anlage 5, die beispielsweise als kompakte Klimaanlage ausgebildet ist, verfügt über wenigstens eine figürlich nicht dargestellte Ansaugöffnung und wenigstens eine ebenfalls figürlich nicht dargestellte Abblasöffnung, die ein Umwälzen der Luft in dem Führerstand 2 ermöglichen. Die Umwälzrichtung ist durch die Pfeile dargestellt.Such a guide table is already known from the current state of the art and illustrated for example in Figure 1 in a sectional side view. The previously known guide table 1 is arranged on the front below the windshield in the cab 2 of a rail vehicle. A guide table cover 3 serves to hold partially sensitive devices and components 4, such as screens, connectors, control levers or the like. The air handling unit 5, which is designed for example as a compact air conditioning system, has at least one suction opening, not shown in the figures, and at least one blow-off opening, likewise not shown figuratively, which circulates the air allow in the cab 2. The direction of circulation is indicated by the arrows.

Insbesondere Lokomotiven, die Kohlezüge bewegen, sind in der Regel hohen Staubbelastungen durch Kohlestaub ausgesetzt. Ein vollständiges Herausfiltern des gesamten Staubgehalts im Führerstand 2 ist aufgrund der hohen Luftmengen technisch sehr aufwendig. Aus diesem Grunde gelangt in der Regel Reststaub in den Führerstand 2, der sich auf den Armaturen und Komponenten des Führertisches 1 absetzt, wodurch deren Funktionsfähigkeit beeinträchtigt wird. Bei größeren Staubablagerungen besteht darüber hinaus ein Sicherheitsrisiko durch Staubverpuffungen.In particular, locomotives that move coal trains are usually exposed to high levels of dust dust from coal dust. A complete filtering of the total dust content in the cab 2 is technically very high due to the high air volumes consuming. For this reason, usually residual dust enters the cab 2, which settles on the fittings and components of the guide table 1, whereby their functionality is impaired. In the case of larger dust deposits, there is also a safety risk due to dust explosions.

In dem in Figur 1 gezeigten Ausführungsbeispiel erfolgt die Ansaugung der Klimaluft ungerichtet, so dass unter der Führertischabdeckung 3 ein Unterdruck entsteht. Dies ist durch die in Figur 1 gezeigten Minuszeichen angedeutet. Der Unterdruck sorgt dafür, dass durch Spalten und Lücken in der Führertischabdeckung 3 unkontrolliert staubhaltige Luft unter den Führungstisch gesaugt wird. Die ist in Figur 1 durch die nicht fett gezeichneten Pfeile skizzenhaft dargestellt.In the embodiment shown in Figure 1, the intake of air conditioning air is undirected, so that under the guide table cover 3, a negative pressure. This is indicated by the minus sign shown in FIG. The negative pressure ensures that uncleaned dust-containing air is sucked under the guide table by gaps and gaps in the guide table cover 3. This is sketchily illustrated in Figure 1 by the bold not shown arrows.

Eine Reinigung aller verschmutzten Komponenten unter und in der Führungstischabdeckung 3 ist aufwendig, da die Führungstischabdeckung 3 die Zugänglichkeit beeinträchtigt und die Oberflächen darüber hinaus stark zerklüftet sind. Es ist daher sinnvoll, die Zeitdauer der notwendigen Grundreinigung so weit wie möglich hinauszuzögern.A cleaning of all soiled components under and in the guide table cover 3 is expensive, since the guide table cover 3 affects the accessibility and the surfaces are also highly rugged. It therefore makes sense to delay the duration of the necessary basic cleaning as much as possible.

Es wurde bereits vorgeschlagen, den Führertisch als geschlossene und staubdichte Einheit auszubilden. Dies ist jedoch aufgrund der vielen in der Führertischabdeckung zum Halten der Komponenten und Bildschirme des Führertisches vorgesehenen Durchführungen ausgesprochen aufwändig.It has already been proposed to form the guide table as a closed and dustproof unit. However, this is extremely expensive due to the many passages provided in the guide table cover for holding the components and screens of the guide table.

Der Erfindung liegt die Aufgabe zugrunde, einen Führertisch der eingangs genannten Art bereitzustellen, mit dem die Staubbelastung seiner Komponenten herabgesetzt ist und der gleichzeitig kostengünstig ist.The invention has for its object to provide a guide table of the type mentioned, with which the dust load of its components is reduced and at the same time is inexpensive.

Die Erfindung löst diese Aufgabe durch eine Luftführung, die sich zwischen der Luftansaugöffnung und der Lufteintrittsöffnung druckdicht erstreckt.The invention solves this problem by an air guide which extends pressure-tight between the air intake opening and the air inlet opening.

Gemäß der vorliegenden Erfindung wird der Aufbau eines Unterdrucks unter dem Führertisch vermieden. Dies erfolgt durch den Einsatz einer druckdichten Luftführung, die den von der Ansaugöffnung der raumlufttechnischen Anlage erzeugten Unterdruck zur Lufteintrittsöffnung des Führertisches kanalisiert. Erfindungsgemäß ist die raumlufttechnische Anlage mit Abstand zur Lufteintrittsöffnung unter der Führertischabdeckung 3 angeordnet. Auf diese Weise kann auf bewährte, dem Stand der Technik bekannte Bauteile zurückgegriffen werden. Das einzige Zusatzteil, das im Rahmen der Erfindung benötigt wird, besteht in dem druckdichten Führungsrohr, das beispielsweise rohr- oder kanalförmig ausgebildet ist und mit seiner einen Öffnung auf die Ansaugöffnung der raumlufttechnischen Anlage aufgesetzt wird, wobei die andere Öffnung des Führungsrohres an dem Bereich des Führertisches anliegt, durch den die Lufteintrittsöffnung begrenzt ist. Der Führertisch ist beispielsweise an der Frontseite des Führerstandes unterhalb der Windschutzscheibe angeordnet, so dass durch die Führertischabdeckung und der Frontseite ein abgeschlossener Hohlraum ausgebildet ist.According to the present invention, the build-up of a negative pressure under the guide table is avoided. This is done by using a pressure-tight air duct, which channels the negative pressure generated by the intake of the ventilation system to the air inlet opening of the guide table. According to the invention the ventilation system is arranged at a distance from the air inlet opening under the guide table cover 3. In this way, recourse can be had to proven components known from the prior art. The only additional part that is required in the invention consists in the pressure-tight guide tube, which is for example tubular or channel-shaped and is placed with its one opening on the suction port of the ventilation system, the other opening of the guide tube at the area of Guide table is applied, through which the air inlet opening is limited. The guide table is arranged, for example, on the front side of the driver's cab below the windscreen, so that a closed cavity is formed by the guide table cover and the front side.

Vorteilhafterweise ist das Führungsrohr sowohl an der raumlufttechnischen Anlage als auch an der Führertischabdeckung dichtend aufgesetzt. Das dichtende Aufsetzen ist im Rahmen der Erfindung jedoch nicht zwangsläufig erforderlich. Wesentlich ist, dass der durch das Ansaugen entstehende Unterdruckanteil unter der Führertischabdeckung geringer ist als der durch das Abblasen der raumlufttechnischen Anlage entstehende Überdruckanteil, so dass insgesamt ein resultierender Überdruck entsteht.Advantageously, the guide tube is placed sealingly both on the ventilation system and on the guide table cover. However, the sealing touchdown is not necessarily required within the scope of the invention. It is essential that the negative pressure component resulting from the suction under the guide table cover is lower than the excess pressure component resulting from the blowing off of the ventilation system, so that overall a resulting overpressure results.

Gemäß einer vorteilhaften Weiterentwicklung ist ein Führungskanal vorgesehen, der zum Führen der Luft zwischen der Abblasöffnung und der Luftaustrittsöffnung vorgesehen ist. Dabei ist es keineswegs notwendig, dass auch der Führungskanal druckdicht ausgestaltet ist. Vielmehr ist es sogar vorteilhaft, wenn nicht der gesamte von der Abblasöffnung der raumlufttechnischen Anlage ausgestoßene Luftstrom über den Führungskanal geführt wird, sondern stattdessen ein Teilluftstrom oder Restluftstrom seitlich unter die Führertischabdeckung austritt und dort für einen geringfügigen Überdruck sorgt. Durch den Überdruck ist der Staubeintritt unter den Führertisch noch weiter herabgesetzt.According to an advantageous further development, a guide channel is provided which is provided for guiding the air between the blow-off opening and the air outlet opening. It is by no means necessary that the guide channel is designed pressure-tight. Rather, it is even advantageous if not the entire discharged from the blowdown of the ventilation system air flow is guided over the guide channel, but instead a partial air flow or residual air flow exits laterally under the guide table cover and there provides for a slight overpressure. Due to the overpressure, the dust entry under the driver's desk is even further reduced.

Gemäß einer diesbezüglich zweckmäßigen Weiterentwicklung weist der Führungskanal eine unter den Führungstisch mündende Bypassöffnung zum Erzeugen eines Bypassstromes auf. Aufgrund der Bypassöffnung kommt es zu einem zusätzlichen Umlenken des von der raumlufttechnischen Anlage abgeblasenen Luftstromes unter die Führungstischabdeckung und somit zu einer Erhöhung des Überdruckes, wodurch der Staubeintritt in den Führungstisch noch weiter herabgesetzt wird.According to an expedient further development, the guide channel has a bypass opening opening under the guide table for generating a bypass flow. Due to the bypass opening, there is an additional deflection of the blown off by the ventilation system air flow under the guide table cover and thus to an increase in the pressure, whereby the dust entry is further reduced in the guide table.

Vorteilhafterweise weist die raumlufttechnische Anlage sowohl ein Heizaggregat als auch eine Kühleinheit auf. Gemäß dieser vorteilhaften Weiterentwicklung ist sowohl ein Heizen des Führerstandes beispielsweise im Winter, aber auch ein Kühlen beispielsweise im Sommer ermöglicht.Advantageously, the ventilation system on both a heating unit and a cooling unit. According to this advantageous development, both heating of the driver's cab, for example, in winter, but also cooling, for example, in the summer allows.

Gemäß einer diesbezüglich zweckmäßigen Weiterentwicklung ist die raumlufttechnische Anlage zum Vorkühlen oder Vorwärmen von in der Führertischabdeckung angeordneten Komponenten eingerichtet. Ein Vorwärmen ist beispielsweise dann erforderlich, wenn die Außentemperatur unter die minimale Betriebstemperatur der Komponenten wie Bildschirme oder dergleichen absinkt. Die minimale Betriebstemperatur liegt beispielsweise bei -20 Grad Celsius. In diesem Zusammenhang ist es auch vorteilhaft, wenn der von der raumlufttechnischen Anlage ausgeblasene Luftstrom über Vorwärmluftführungen zu den temperaturempfindlichen Instrumenten geführt wird. Die Vorwärmluftführungen sind vorteilhafterweise durch Klappen oder dergleichen aktivierbar.According to an expedient further development, the ventilation and air conditioning system is adapted for pre-cooling or preheating components arranged in the driver's desk cover. Preheating is required, for example, when the outside temperature is below the minimum operating temperature of the components such as screens or the like decreases. For example, the minimum operating temperature is -20 degrees Celsius. In this context, it is also advantageous if the air flow blown out of the ventilation system is guided via preheat air ducts to the temperature-sensitive instruments. The preheating air ducts are advantageously activated by flaps or the like.

Vorteilhafterweise verfügt die Bypassöffnung über einen Feinfilter. Der Feinfilter verhindert die Staubbelastung durch den von der raumlufttechnischen Anlage ausgeblasenen Luftstrom.Advantageously, the bypass opening has a fine filter. The fine filter prevents dust from being absorbed by the air flow discharged by the ventilation system.

FIG. 2
show a guide table according to an embodiment of the present invention each in a side view.

Figur 1 zeigt einen Führertisch 1 gemäß dem Stand der Technik, der bereits vorausgehend beschrieben wurde.Figure 1 shows a guide table 1 according to the prior art, which has already been described above.

Figur 2 zeigt ein Ausführungsbeispiel eines erfindungsgemäßen Führertisches 1, der zur Montage in einem Führerstand 2 vorgesehen ist. Der Führertisch 1 weist Komponenten 4 zum Bedienen und Steuern eines Triebwagens eines schienengebundenen Fahrzeugs auf. Solche Komponenten sind beispielsweise Bildschirme, Anzeigeinstrumente, Steuerungshebel 4 oder der gleichen. Unter einer Führungstischabdeckung 3 ist eine kompakte raumlufttechnische Anlage 5 vorgesehen, bei der es sich in dem gezeigten Ausführungsbeispiel um eine kompakte Klimaanlage handelt. Die Klimaanlage 5 verfügt über eine in Figur 2 nicht erkennbare Ansaugöffnung für die Umluft und eine Frischluftansaugöffnung zum Ansaugen von atmosphärischer Luft über eine Frischluftzufuhr 6. Um ein Umwälzen der Luft im Führerstand 2 zu ermöglichen, weist die Führertischabdeckung eine Lufteintrittsöffnung 7 auf und eine Luftaustrittsöffnung 8 auf. Die Luftaustrittsöffnung 8 ist in unmittelbarer Nähe einer Windschutzscheibe 9 des Führerstandes 2 angeordnet. Zwischen der Ansaugöffnung der Klimaanlage 5 und der Lufteintrittsöffnung 7 der Führertischabdeckung 3 erstreckt sich eine Luftführung 10, die rohrförmig ausgebildet ist und an beiden Seiten über Befestigungsflansche zum druckdichten Anschluss an die Klimaanlage 5 einerseits und an die Führertischabdeckung 3 andererseits verfügt. Zum Führen des aus der Klimaanlage 5 austretenden Luftstromes ist ein Führungskanal 11 vorgesehen, der sich zwischen der Abblasöffnung der Klimaanlage 5 und der Luftaustrittsöffnung 8 der Führertischabdeckung 3 erstreckt. In dem Führungskanal 11 ist ein Bypasskanal 12 mit einer Bypassöffnung 13 vorgesehen, der mit einem Feinfilter 14 ausgerüstet ist.Figure 2 shows an embodiment of a guide table 1 according to the invention, which is provided for mounting in a cab 2. The driver's desk 1 has components 4 for operating and controlling a railcar of a rail-bound vehicle. Such components are for example screens, Indicating instruments, control levers 4 or the like. Under a guide table cover 3, a compact ventilation system 5 is provided, which is a compact air conditioning in the embodiment shown. The air conditioning system 5 has a suction opening for the circulating air, which is not visible in FIG. 2, and a fresh air intake opening for drawing in atmospheric air via a fresh air supply 6. In order to allow the air in the driver's cab 2 to be circulated, the guide table cover has an air inlet opening 7 and an air outlet opening 8 on. The air outlet opening 8 is arranged in the immediate vicinity of a windshield 9 of the driver's cab 2. Between the intake opening of the air conditioner 5 and the air inlet opening 7 of the guide table cover 3 extends an air guide 10 which is tubular and has on both sides via mounting flanges for pressure-tight connection to the air conditioner 5 on the one hand and on the guide table cover 3 on the other. To guide the exiting the air conditioning 5 air flow, a guide channel 11 is provided, which extends between the blow-off opening of the air conditioner 5 and the air outlet opening 8 of the guide table cover 3. In the guide channel 11, a bypass channel 12 is provided with a bypass opening 13 which is equipped with a fine filter 14.

Durch die Klimaanlage 5 kann sowohl Frischluft von außerhalb des Führungstandes 2 angesaugt als auch Luft in dem Führerstand 2 umgewälzt werden, wie durch die Pfeile in den Figuren 1 und 2 angedeutet ist. Durch die Luftführung 10, die nicht dichtend zwischen Klimagerät 5 und Führertischabdeckung 3 montiert ist, ist das Ausbilden eines Unterdruckes unterhalb der Führertischabdeckung 3 vermieden oder jedenfalls nur in einem weit geringeren Maße ermöglicht, als ein Überdruck durch den Bypasskanal 12 und die Bypassöffnung 13 erzeugt wird. Auf diese Weise wird insgesamt ein resultierender Überdruck unterhalb der Führertischabdeckung 3 erzeugt, so dass ein Ansaugen von Luft durch die Durchführungen zum Halten der Komponenten des Führertisches 1 vermieden ist. Die Verschmutzung der Komponenten oder Bauteile ist daher herabgesetzt.By the air conditioner 5, both fresh air sucked from outside the management stand 2 and air in the cab 2 are circulated, as indicated by the arrows in Figures 1 and 2. By the air guide 10, which is not mounted sealingly between the air conditioner 5 and the guide table cover 3, the formation of a negative pressure below the guide table cover 3 is avoided or at least only possible to a much lesser extent than an overpressure generated by the bypass channel 12 and the bypass opening 13 becomes. In this way, a total resulting positive pressure below the guide table cover 3 is generated, so that an intake of air through the passages for holding the components of the guide table 1 is avoided. The pollution of the components or components is therefore reduced.
