Description
Die Erfindung betrifft eine Vorrichtung zum thermischen Isolieren von Backenschienen bei beheizten Weichen und ein Verfahren zum Fixieren der Vorrichtung.
Diese Vorrichtung wird insbesondere bei Schienenbahnen angewendet, bei denen im Winter mit einem Schnee- und/oder Eisbelag auf Weichen oder Weichenteilen zu rechnen ist.
Zum Erhalt der Funktionsfähigkeit von Weichen werden diese in den Wintermonaten, in Abhängigkeit der vorherrschenden Witterung, im Bereich der Zungen und Verschlusseinrichtungen meist elektrisch beheizt, um Eis und Schnee abzutauen. Über die Länge des Anliegebereichs der Weichenzungen werden in der Regel die Backenschienen mittels elektrischer Heizstäbe erwärmt.
Die zum Heizen verwendete Energie wird dabei über die gesamte Oberfläche der Schiene in die Umgebung abgegeben, obwohl sie nur in dem Bereich zwischen Backenschiene und Weichenzunge benötigt wird. Das bedeutet, dass ca. 70 % der Schienenfläche unnötig Energie abgibt.
Gleichfalls wird durch Strahlung, Konvektion und bewegte Luft Wärmeenergie ungenutzt abgegeben.
Die ungenutzt abgegebene Energie kann verringert werden, wenn Teile der Backenschiene thermisch isoliert werden. Hierfür ist in der

This device is used in particular in railways, where in winter with a snow and / or ice covering on switches or switch parts is to be expected.
In order to maintain the functionality of switches, they are usually heated electrically in the winter months, depending on the prevailing weather, in the area of the tongues and closing devices in order to defrost ice and snow. Over the length of the contact area of the switch blades, the cheek rails are usually heated by means of electrical heating rods.
The energy used for heating is discharged into the environment over the entire surface of the rail, although it is needed only in the area between the stock rail and switch blade. This means that about 70% of the rail surface unnecessarily emits energy.
Likewise, heat energy is released unused by radiation, convection and moving air.
The unused energy released can be reduced by thermally insulating parts of the stock rail. This is in the

A similar fixing of the thermal insulation is in the
Die im Stand der Technik bekannten Schienenisolierungen haben sich jedoch in der Praxis bezüglich ihrer thermischen und mechanischen Belastbarkeit nicht bewährt.However, the rail insulation known in the prior art have not proven in practice with respect to their thermal and mechanical strength.
Es ist somit Aufgabe der Erfindung, eine Backenschienenisolierung bereitzustellen, die einerseits akzeptable thermische Isoliereigenschaften bietet und andererseits den hohen mechanischen Belastungen im Gleisbereich standhält. Weiterhin soll die Backenschienenisolierung einfach zu montieren und bei bereits bestehenden beheizten Weichen leicht nachrüstbar sein.It is therefore an object of the invention to provide a baking rail insulation, on the one hand offers acceptable thermal insulation properties and on the other hand withstand the high mechanical loads in the track area. Furthermore, the back bar insulation should be easy to install and easy to retrofit with existing heated points.
Diese Aufgaben werden durch die in Anspruch 1 angegebenen Merkmale der erfindungsgemäßen Vorrichtung und durch das in Anspruch 4 beschriebene Verfahren zum Fixieren der Vorrichtung gelöst.These objects are achieved by the features specified in
Vorteilhafte Ausgestaltungen der erfindungsgemäßen Vorrichtung sind Gegenstand der abhängigen Ansprüche 2 bis 3.
Eine vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens ist Gegenstand des Anspruchs 5.Advantageous embodiments of the device according to the invention are the subject of the
An advantageous embodiment of the method according to the invention is the subject of
Die erfindungsgemäße Vorrichtung nach Anspruch 1 besteht aus zwei Komponenten. Die Schienenstegisolierung isoliert den Schienensteg und Teile des Schienenkopfes. Die Schienenfußisolierung verhindert, dass Wärmeleistung über den Schienenfuß in das Gleisbett, bzw. die Schwellen verloren geht. Beide Komponenten bestehen aus wärmeisolierendem Dämm-Material geeigneter Dicke und Dichte. Die Schienenfußisolierung umgreift den Schienenfuß derart, dass sie an den Seiten des Schienenfußes über dessen Höhe hinausragt.
Die Schienenstegisolierung ist so geformt, dass sie sowohl am Schienenkopf als auch auf der Oberseite des Schienenfußes formschlüssig anliegt. Die Formgebung der beiden Komponenten ist dabei so aufeinander und auf die Form des Schienenprofils abgestimmt, dass die Schienenstegisolierung auf dem Schienenfuß auch an der Schienenfußisolierung anliegt und dadurch zwischen Schienenkopf, Schienenfuß und Schienenfußisolierung festgeklemmt ist. Damit am Schienensteg die Weichenheizung angebracht werden kann, enthält die Schienenstegisolierung entsprechend ausgelegte Aussparungen auf der dem Schienensteg zugewandten Seite.The device according to the invention according to
The rail bridge insulation is shaped so that it rests positively on both the rail head and on the top of the rail foot. The shape of the two components is so matched to each other and to the shape of the rail profile that the rail bar insulation rests on the rail also on the Schienenfußisolierung and is thus clamped between the rail head, rail and Fußfußisolierung. So that the point heater can be mounted on the rail bridge, the rail bridge insulation contains correspondingly designed recesses on the rail web side facing.
Hierbei wird die den Schienenfuß umgreifende Schienenfußisolierung um den Schienenfuß so weit herumgeführt, dass sie oberhalb des Schienenfußes zum Schienensteg hinragt. Dadurch ist der Anschlag zum Einklemmen der Schienenstegisolierung auf dem Schienenfuß etwas in Richtung zum Schienensteg hin verschoben. Durch die dadurch erzeugte konstruktive Klemmwirkung bei der Schienenstegisolierung, fixiert sich diese bei der Montage von selbst. Diese konstruktive Ausformung der Schienenfußisolierung verhindert, dass durch die mechanischen Einflüsse aus dem Bahnbetrieb die Schienenstegisolierung vom Schienenfuß gleitet.Here, the rail foot encompassing rail foot insulation is guided around the rail foot so far that it protrudes above the rail foot to the rail web. As a result, the stop for clamping the rail bridge insulation on the rail foot is slightly displaced in the direction of the rail web. Due to the constructive clamping effect generated in the rail web insulation, this fixes itself during assembly by itself. This structural design of the rail foot insulation prevents the rail web insulation from sliding through the mechanical influences from railway operation.
Anspruch 2 beschreibt eine vorteilhafte Ausgestaltung des Anspruchs 1. Gemäß Anspruch 2 ist die Höhe der Schienenstegisolierung so groß gewählt, dass sie bis zur Höhe der Schienenkopfoberseite ragt. Dabei liegt sie durchgehend am Schienenkopf formschlüssig an. Somit ergibt sich eine große Kontaktfläche zwischen Schienenstegisolierung und Schienenkopf.
Die Wäremedämmungs-Komponenten der Backenschienenisolierung bestehen gemäß Anspruch 3 vorteilhaft aus geschäumtem Kunststoff, z.B. Polypropylen (EPP) mit geeigneter Dichte. Dieses Material hat gute wärmedämmende und mechanische Eigenschaften. Sie sind mit geeigneten Verfahren in der Massenherstellung günstig herzustellen.The thermal insulation components of the cheek bar insulation are advantageously made of foamed plastic, e.g. Polypropylene (EPP) with suitable density. This material has good thermal and mechanical properties. They are inexpensive to produce by suitable methods in mass production.
Gemäß Anspruch 4 wird die Schienenstegisolierung zwischen Schienenkopf, Schienenfuß und Schienenfußisolierung eingeklemmt. Vor dem Einsetzen der Schienenstegisolierung werden notwendige Aussparungen für Montagehindernisse in diese eingearbeitet. Nachdem die Schienenstegisolierung am Schienensteg montiert wurde, wird die Schienenfußisolierung so unter dem Schienenfuß montiert, dass die über den Schienenfuß ragende Schienenfußisolierung als unterer Anschlag für die Schienenstegisolierung dient.According to
Besonders vorteilhaft wird gemäß Anspruch 5, vor dem Anbringen der Schienenstegisolierung die Kontaktfläche zwischen Schienenstegisolierung und Schienenkopf mit einem Klebstoff versehen, sodass nach dem Einklemmen die Schienenstegisolierung am Schienenkopf zusätzlich zur Klemmkraft auch durch die Klebkraft fixiert wird.According to
Die Erfindung wird im Folgenden anhand eines Ausführungsbeispiels und einer Figur näher erläutert:
-
Fig. 1 zeigt beispielhaft eine Ausgestaltung der Erfindung.
Die über die Schienenfußhöhe hinausragenden Anteile der Schienenfußisolierung (2) sind vorteilhaft in Richtung des Schienenstegs (6) um den Schienenfuß (5) herumgezogen. Um den erforderlichen Raum für die Schienenbefestigungsklammern frei zu halten, ist die Schienenfußisolierung (2) vorteilhaft asymmetrisch bezüglich der Schienenmitte geformt. Die Seite mit der kurzen Nase ist für die der Zunge zugewandten Seite vorgesehen. Die Seite mit der langen Nase definiert an der Backenschienenaußenseite den Anschlag für die Schienenstegisolierung (1). Die Schienenstegisolierung (1) ist so geformt, dass sie, wenn sie fest an der Schienenfußisolierung (2) anliegt, auch gleichzeitig auf der Oberseite des Schienenfußes (5) und am Schienenkopf (7) formschlüssig anliegt.
Die Schienenstegisolierung (1) ist vorteilhaft am Schienenkopf (7) bis hoch zur Schienenoberkante ausgeführt. Dies ermöglicht eine große Fläche (3) zum Verkleben mit dem Schienenkopf (7).

Fig. 1 shows an example of an embodiment of the invention.
The portions of the rail foot insulation (2) projecting beyond the rail foot height are advantageously drawn around the rail foot (5) in the direction of the rail web (6). In order to keep the space required for the rail mounting brackets free, the rail foot insulation (2) is advantageously shaped asymmetrically with respect to the rail center. The side with the short nose is provided for the tongue-facing side. The side with the long nose defines on the cheek rail outside the stop for the rail web insulation (1). The rail bridge insulation (1) is shaped so that, when it rests firmly against the rail foot insulation (2), it also bears on the upper side of the rail foot (5) and on the rail head (7) in a form-fitting manner.
The rail web insulation (1) is advantageously carried out on the rail head (7) up to the top of the rail. This allows a large area (3) for bonding to the rail head (7).

Die elektrischen Weichenheizelemente sind am Backenschienensteg (6) auf der der Zungenschiene zugewandten Seite befestigt. Auf der der Zungenschiene abgewandten Seite des Schienenstegs wird die Schienenstegisolierung (1) befestigt, deren Länge variabel gestaltbar ist. Vorteilhaft wird die Länge der Schienenstegisolierteile zu 1,20 m gewählt. Die Schienenstegisolierteile sind je nach Schienenform am Schienenfuß (5) etwa 25 mm - 35 mm und unterhalb des Schienenkopfes (7) etwa 35mm - 45 mm dick. An der Seite des Schienenkopfes (7) reicht die Isolierung in einer Dicke von etwa 20 mm bis hoch zur Schienenoberkante. Zur Befestigung der Schienenstegisolierung wird zunächst der Schienenkopf (7) gereinigt. Dann werden - soweit erforderlich die Schienenstegisolierteile (1) vorbereitet, d.h. sie werden mit Ausnehmungen (4) an die Einbauteile angepasst. An der schmalen Stelle ist die Schienenstegisolierung (1) dabei mindestens 15 mm dick. Nun wird an den Klebeflächen (3) der Schienenstegisolierung (1) der Klebstoff aufgebracht. Die mithilfe eines geeigneten Klebstoffes (vorteilhaft eines PUR 1-Komponentenklebstoffs) versehene Schienenstegisolierung (1) wird nun so befestigt, dass sie seitlich am Schienenkopf (7) festgeklebt ist. Abschließend wird die Schienenfußisolierung (2) montiert, so dass die Schienenstegisolierung (1) gleichzeitig zwischen Schienenkopf (7), Schienenfuß (5) und Schienenfußisolierung (2) formschlüssig eingeklemmt ist. Die Schienenfußisolierungen (2) werden dabei in allen isolierten Schwellenfächern jeweils unter dem Backenschienenfuß montiert. Die Schienenfußisolierungen (2) sind in Schienenlängsrichtung etwa 0,13 m lang. Je Schwellenfach sind in diesem Beispiel drei Schienenfußisolierungen eingebracht. Sie umgreifen den Schienenfuß (5) und sind oberhalb des Schienenfußes auf der Seite der Schienenstegisolierung noch etwa 20 mm um den Schienenfuß zum Schienensteg (6) hin herumgeführt. Auf der gegenüberliegenden Seite beträgt die Überdeckung nur ca. 6 mm zur Gewährleistung der einfachen Montierbarkeit.The electrical Weichenheizelemente are attached to the jaw rail web (6) on the tongue rail side facing. On the tongue rail remote from the side of the rail web railing insulation (1) is fixed, the length of which can be variably designed. Advantageously, the length of the Schienenstegisolierteile is selected to 1.20 m. Depending on the rail shape, the rail web insulating parts are approximately 25 mm to 35 mm on the rail foot (5) and approximately 35 mm to 45 mm below the rail head (7). On the side of the rail head (7), the insulation reaches in a thickness of about 20 mm up to the top of the rail. To fix the rail web insulation, the rail head (7) is first cleaned. Then - if necessary, the rail web insulation parts (1) prepared, ie they are adjusted with recesses (4) to the mounting parts.
