Description

Beschreibung description
Schienenfahrzeug mit einem Ansaugrauchmelder Rail vehicle with a aspirating smoke detector
Die Erfindung bezieht sich auf ein Schienenfahrzeug mit einem Ansaugrauchmelder, der über eine Leitung mit wenigstens einem Ansaugendstück definierten Öffnungsquerschnitts zur Entnahme von Luftproben verbunden ist. The invention relates to a rail vehicle with a Ansaugrauchmelder, which is connected via a line with at least one Ansaugendstück defined opening cross-section for the removal of air samples.
Bei einem solchen Schienenfahrzeug sind typischerweise eine Mehrzahl von Ansaugendstücken definierten Öffnungsquerschnitts vorgesehen, die beispielsweise über den Innenraum des Fahrzeugs verteilt sind. Zu deren Verbindung mit dem An- saugrauchmelder dient eine Leitungsanordnung. Diese Leitungsanordnung wird bisher von einem starren Rohrsystem gebildet. Zur Sicherstellung einer gleichmäßigen Luftprobenentnahme aus Überwachungsbereichen innerhalb des Schienenfahrzeugs sind einzelne Rohrstücke untereinander verklebt und in diese In such a rail vehicle, a plurality of suction pieces of defined opening cross-section are typically provided, which are distributed over the interior of the vehicle, for example. A line arrangement serves for their connection to the suction smoke detector. This line arrangement has hitherto been formed by a rigid pipe system. To ensure a uniform air sampling from monitoring areas within the rail vehicle individual pieces of pipe are glued together and in this
Rohrstücke sind Ansaugöffnungen mit definierten Bohrungs¬ durchmessern eingebracht. Pipe pieces are introduced intake openings with defined bore ¬ diameters.
Aufgrund einer Ausbaucharakteristik im Deckenbereich eines Schienenfahrzeugs, in dem beispielsweise Klimakanäle, Leuch- tenbänder und Kabeltrassen angeordnet sind, ist die Installa¬ tion einer starren Verrohrung mit hohem Aufwand verbunden. Due to a characteristic of expanding in the ceiling area of a rail vehicle in which, for example, air conditioning ducts, luminaire are arranged tenbänder and cable trays, the installa tion ¬ a rigid casing is associated with high costs.
Ausgehend hiervon liegt der Erfindung die Aufgabe zu Grunde, ein Schienenfahrzeug der eingangs genannten Art derart wei- terzuentwickeln, das eine Montierbarkeit für die Leitungen von dem Ansaugrauchmelder zu den Ansaugendstücken vereinfacht ist . Proceeding from this, the object of the invention is to further develop a rail vehicle of the type mentioned at the outset such that it is easier to assemble the lines from the aspirating smoke detector to the suction pieces.
Diese Aufgabe wird bei dem Schienenfahrzeug dadurch gelöst, dass wenigstens ein von dem Ansaugendstück in Richtung auf den Ansaugrauchmelder abgehendes Leitungsstück aus flexiblem Material gebildet ist. Dabei kann die Leitung insgesamt aus flexiblen Schlauch- und/oder Rohrstücken aufgebaut sein, so dass die gesamte Leitung zwischen Ansaugrauchmelder und dem wenigstens einen Ansaugendstück flexibel gehalten ist. In dieser Weise ergibt sich auch eine Flexibilität bei der Aus¬ wahl von Verlegewegen für die Leitung im Fahrzeug, denn Ein- bauten oder Hindernisse können flexibel umgangen werden und Montageunterlagen müssen nicht an jede Ausbausituation ange- passt werden. This object is achieved in the rail vehicle in that at least one of the Ansaugendstück in the direction of the aspirating smoke detector outgoing line piece is formed of flexible material. In this case, the line can be constructed in total of flexible hose and / or pipe sections, so that the entire line between Ansaugrauchmelder and the at least one Ansaugendstück is kept flexible. In this way, there is also a flexibility in the ¬ selection of laying paths for the line in the vehicle, because built-in or obstacles can be flexibly circumvented and assembly documents must not be adapted to any configuration situation.
Die Montage der Leitung kann weiter dadurch vereinfacht wer- den, dass der Öffnungsquerschnitt mit Hilfe eines Schrumpf- schlauchs festgelegt ist. Dies gewährleistet einen geringeren Aufwand im Hinblick auf darauf bezogene Wartungsarbeiten. Solche Arbeiten werden weniger umfangreich erforderlich sein, denn sie beruhen im Stand der Technik auch auf Vandalismus und Sabotage. Dabei ist es von Bedeutung, dass die zum Fest¬ legen des Öffnungsquerschnitts bisher eingesetzten Banderolen leicht zerstörbar und die Ansaugöffnungen als solche dann erkennbar und zu vandalisieren sind. Demgegenüber kann das wenigstens eine Ansaugendstück in einem Innenraum des Schienenfahrzeugs verdeckt angeordnet sein. Ei¬ ne günstige Anordnungsvariante kann darin bestehen, dass das wenigstens eine Ansaugendstück im Bereich einer Gepäckablage montiert ist. The assembly of the line can be further simplified by the fact that the opening cross-section is determined by means of a shrink tube. This ensures less effort in terms of related maintenance. Such work will be less extensive, because they are based in the prior art on vandalism and sabotage. It is important that the bands at a fixed ¬ place the opening cross section previously used easily destroyed and the suction openings, as such, are recognizable and vandalisieren. In contrast, the at least one suction piece can be concealed in an interior space of the rail vehicle. Ei ¬ ne favorable arrangement variant may consist in that the at least one Ansaugendstück is mounted in the region of a luggage rack.
Es ist ersichtlich, dass die vorstehende Vorgehensweise zur Auslegung einer Leitung zwischen dem Ansaugrauchmelder und dem Ansaugendstück in derselben Weise für sämtliche, im Innenraum des Schienenfahrzeugs vorgesehene Ansaugendstücke vorgenommen werden kann. In diesem Fall wären sämtliche Leitungen Teil einer Leitungsanordnung, die nach Bedarf T- Stücke, Winkelstücke und/oder Reduzierungen aufweisen kann. Diese Vorgehensweise ist montagefreundlicher als die Lösungen im Stand der Technik, bei denen häufig einzelne starre It can be seen that the above procedure for designing a line between the aspirating smoke detector and the suction piece can be made in the same way for all suction pieces provided in the interior of the rail vehicle. In this case, all the conduits would be part of a conduit arrangement which may have T-pieces, elbows and / or reducers as needed. This approach is easier to install than the solutions in the prior art, where often single rigid
Rohrstücke untereinander verklebt sind. Gegenüber der verklebten Verrohrung entstehen somit geringere Wartungs- und Reparaturkosten und eine Darstellung in LCC-Analysen ist einfacher . Ein Ausführungsbeispiel der Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnungen noch näher erläutert. Es zeigen: Pipe pieces are glued together. Compared to the glued piping, lower maintenance and repair costs are incurred and a representation in LCC analyzes is easier. An embodiment of the invention will be explained in more detail with reference to the drawings. Show it:
Figur 1 eine schematische Ansicht einer Rauchmeldeanordnung, FIG. 1 is a schematic view of a smoke detection system;
Figur 2 eine perspektivische Ansicht einer Einbausitu- ation eines Teils der Rauchmeldeanordnung von FIG. 2 shows a perspective view of a mounting situation of a part of the smoke alarm arrangement of FIG
Figur 1. FIG. 1
Wie aus Figur 1 ersichtlich ist, ist ein Ansaugrauchmelder 1 über einen Luftfilter 2 mit einer Leitungsanordnung verbun- den, die mit Hilfe diverser Halteelemente 3 im Innenraum ei¬ nes Schienenfahrzeugs anbringbar ist. As is apparent from Figure 1, a Aspirating 1 via an air filter 2 is provided with conduit means to connectedness, which is attachable by means of various holding members 3 in the interior egg ¬ nes rail vehicle.
Im dargestellten Ausführungsbeispiel sind insgesamt drei An¬ saugendstücke 4 über flexible Schlauch- oder Rohrstücke 5 ge- ringen Durchmessers über Reduzierstücke 6 und eine Kupplung 7 bzw. T-Stücke 8 an eine flexible Haupt-Rohrleitung 9 ange¬ schlossen. Dabei reicht die Haupt-Rohrleitung 9 unter Einbeziehung der T-Stücke 8 von dem Luftfilter 2 bis zu der Kupplung 7, die dem entferntest gelegenen Ansaugendstück 4 zuge- ordnet ist. In the illustrated embodiment, a total of three An ¬ sucking pieces 4 via flexible hose or pipe sections 5 of small diameter via reducers 6 and a coupling 7 or T-pieces 8 to a flexible main pipe 9 is ¬ closed. In this case, the main pipeline 9, including the T-pieces 8, extends from the air filter 2 as far as the coupling 7, which is assigned to the remainder of the suction piece 4.
Insgesamt wird somit die Rauchmeldeanordnung wenigstens ab dem Luftfilter 2 ausschließlich von flexiblen Schlauch- und Rohrstücken gebildet. Zur Verbindung der einzelnen Leitungs- abschnitte 5, 9 dienen handelsübliche Reduzierstücke, T-Overall, therefore, the smoke detection device is formed at least from the air filter 2 exclusively of flexible hose and pipe sections. For the connection of the individual line sections 5, 9 are commercially available reducers, T-
Stücke, ggf. Winkelstücke, wie sie bei konventionellen Ver- schraubungssystemen mit Dichteinsätzen gebräuchlich sind. Pieces, if necessary, contra-angle handpieces, as used in conventional screw joint systems with sealing inserts.
Es ist hervorzuheben, dass die Ansaugendstücke 4 mit Hilfe von aufgeschrumpften Schrumpfschlauchabschnitten 10 auf einen definierten Öffnungsdurchmesser fest gelegt sind. In Figur 2 ist erkennbar, dass von der Haupt-Rohrleitung 9 über das T-Stück 8 und das flexible Schlauch- oder Rohrstück 5 das Ansaugendstück 4 angeschlossen ist. Das Ansaugendstück 4 befindet sich in einem Seitenwandbereich eines Schienen- fahrzeugs, in dem eine Gepäckablage montiert wird. It should be emphasized that the Ansaugendstücke 4 are fixed by means of shrunk shrink tubing sections 10 to a defined opening diameter. In Figure 2 it can be seen that the suction pipe 4 is connected from the main pipe 9 via the tee 8 and the flexible hose or pipe section 5. The suction piece 4 is located in a side wall region of a rail vehicle in which a luggage rack is mounted.
Eine Positionierung des Ansaugendstücks 4 erfolgt über ein Halteelement 11, welches rohbauseitig befestigt. A positioning of the Ansaugendstücks 4 via a holding element 11, which fastened on the shell side.
