Description

Die vorliegende Erfindung bezieht sich auf ein Lichtsignal zur Aufstellung im Bereich eines Verkehrsweges, insbesondere eines Eisenbahngleises, und zur Anzeige von Signalbegriffen.The present invention relates to a light signal for installation in the area of a traffic route, in particular a railway track, and for displaying signal terms.

Lichtsignale werden zur Steuerung von Verkehrsflüssen in vielfältigster Weise im Strassen-, Eisenbahn-, Flug- und Schiffsverkehr eingesetzt. Sogenannte Zwergsignale werden bei den Schweizerischen Bundesbahnen (SBB) und bei mehr als 30 Privatbahnen verwendet und dienen als Lichtsignal zur Sicherung von Fahrstrassen innerhalb von Bahnhofs- und Rangierbereichen. Zwergsignale erfüllen damit sowohl Funktionen für den Rangier- als auch den Zugfahrbetrieb. In der Regel werden Zwergsignale in der Schweiz immer links vom Gleis aufgestellt. Zwergsignale befinden sich direkt am Boden neben dem Gleis, nur in speziellen Einzelfällen werden sie zur besseren Sichtbarkeit erhöht angebracht. Ein Zwergsignal besitzt drei weisse Lampen bzw. drei Leuchten in L-förmiger Anordnung. In der Schweiz kann ein Zwergsignal drei verschiedene Signalbegriffe anzeigent:

  • HALT,
  • FAHRT MIT VORSICHT oder kurz VORSICHT, und
  • FAHRT.
Auf der Rückseite eines Zwergsignals werden die Begriffe VORSICHT oder FAHRT mit einem weissen Licht angezeigt; dazu wird die Lichtquelle für die obere Leuchte benutzt; das Licht wird dabei über einen Spiegel auf die Rückseite geleitet. Diese Rücksignalisierung als leuchtender schräger Balken bedeutet, dass eine Fahrstrasse auf FAHRT oder auf VORSICHT freigegeben ist und somit ein entgegenkommendes Fahrzeug zu erwarten ist. Die Rücksignalisierung erlaubt auch dass ein Lokführer das Zwergsignal von hinten lesen kann, was insbesondere im Rangierdienst von Bedeutung sein kann.Light signals are used to control traffic flows in a wide variety of ways in road, rail, air and ship traffic. So-called dwarf signals are used by the Swiss Federal Railways (SBB) and by more than 30 private railways and serve as light signals to protect routes within station and shunting areas. Dwarf signals thus perform functions for both maneuvering and train operation. As a rule, dwarf signals are always placed to the left of the track in Switzerland. Dwarf signals are located directly on the floor next to the track, only in special individual cases are they raised for better visibility. A dwarf signal has three white lamps or three lights in an L-shaped arrangement. In Switzerland, a dwarf signal can display three different signal terms:
  • STOP,
  • RIDE WITH CAUTION or CAUTION for short, and
  • JOURNEY.
On the back of a dwarf signal, the words CAUTION or DRIVE are displayed with a white light; the light source for the upper lamp is used for this; the light is directed to the back via a mirror. This return signaling as a glowing, inclined bar means that a route has been cleared for DRIVING or for CAUTION and an oncoming vehicle is therefore to be expected. The reverse signaling also allows a train driver to read the dwarf signal from behind, which can be particularly important in shunting.

Im Besonderen bei Gleichstrombahnen stellt aber die Aufstellung dieser Zwergsignale gewisse Anforderungen an den Bahnbetreiber. Es sind nämlich die Schutzerde des Niederspannungsnetzes zwischen dem Zwergsignal und dem Stellwerks, die Bauwerkserde des gesamten Bahntrassee und die Bahnerde der Gleichstromspeisung sauber galvanisch voneinander zu trennen. Aus diesem Grunde werden die Zwergsignale bei Gleichstrombahnen auf separaten vorgefertigten Betonsockeln montiert. Obwohl die galvanische Trennung mit diesen Betonsockeln sichergestellt ist, haben diese allerdings den Nachteil, dass sie vom Handling her aufwändig und daher entsprechend unbeliebt bei den Infrastrukturbetreibern sind.In particular in the case of direct current railways, the installation of these dwarf signals places certain demands on the Railway operator. This is because the protective earth of the low-voltage network between the dwarf signal and the signal box, the building earth of the entire railway line and the railway earth of the DC power supply must be galvanically separated from each other. For this reason, the dwarf signals for DC railways are mounted on separate prefabricated concrete bases. Although the galvanic isolation is ensured with these concrete bases, they have the disadvantage that they are complex to handle and therefore correspondingly unpopular with the infrastructure managers.

Die Gebrauchsmusterschrift DE 20 2015 106 315 U1 zeigt ein Lichtsignal zur Aufstellung im Bereich eines Verkehrsweges und zur Anzeige von Signalbegriffen mit einem zweiteiligen Signalmast, umfassend einen Fußteil, einen höhenverstellbaren Teil, der in verschiedenen Montagehöhen mit dem Fußteil verbindbar ist, und einen an dem höhenverstellbaren Teil befestigten Signalkopf mit entsprechend zur Anzeige der Signalbegriffe vorgesehenen Signalleuchten.The utility model DE 20 2015 106 315 U1 shows a light signal for installation in the area of a traffic route and for displaying signal terms with a two-part signal mast, comprising a foot part, a height-adjustable part that can be connected to the foot part at different mounting heights, and a signal head attached to the height-adjustable part with correspondingly for displaying the Signal terms provided signal lights.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde ein Lichtsignal zur Aufstellung im Bereich eines Verkehrsweges, insbesondere eines Eisenbahngleises, und zur Anzeige von Signalbegriffen anzugeben, welches im Besonderen die Anforderung an die galvanische Trennung der verschiedenen Bezugserdungen erfüllt und sich zugleich auch durch eine einfache Montierbarkeit auszeichnet.The present invention is therefore based on the object of specifying a light signal for installation in the area of a traffic route, in particular a railway track, and for displaying signal terms, which in particular fulfills the requirement for the electrical isolation of the various reference earths and at the same time is also characterized by simple mounting .

Diese Aufgabe wird erfindungsgemäss durch ein Lichtsignal zur Aufstellung im Bereich eines Verkehrsweges und zur Anzeige von Signalbegriffen, umfassend:

  1. a) einen zweiteiligen Signalmast, umfassend einen Fussteil und einen höhenverstellbaren Teil, wobei der höhenverstellbare Teil in verschiedenen Montagehöhen mit dem Fussteil verbindbar ist;
  2. b) eine Isolierschicht, insbesondere eine Isolierplatte, zur galvanischen Trennung des Fussteils von dem höhenverstellbaren Teil,
  3. c) Isolierelemente, wie z.B. Unterlegscheiben und/oder Gewindebuchsen aus Kunststoff, zur galvanischen Trennung der Verbindung des Fussteils und des höhenverstellbaren Teils;
  4. d) ein den Signalmast zumindest teilweise umgebendes Hüllelement aus einem isolierenden Werkstoff; und
  5. e) einen an dem höhenverstellbaren Teil befestigten Signalkopf mit entsprechend zur Anzeige der Signalbegriffe vorgesehenen Signallampen.
According to the invention, this object is achieved by a light signal for setting up in the area of a traffic route and for displaying signal terms, comprising:
  1. a) a two-part signal mast, comprising a foot part and a height-adjustable part, the height-adjustable part being connectable to the foot part at different mounting heights;
  2. b) an insulating layer, in particular an insulating plate, for galvanically separating the foot part from the height-adjustable part,
  3. c) insulating elements, such as washers and / or threaded bushings made of plastic, for the electrical isolation of the connection of the foot part and the height-adjustable part;
  4. d) an enveloping element at least partially surrounding the signal mast made of an insulating material; and
  5. e) a signal head attached to the height-adjustable part with correspondingly for displaying the signal terms provided signal lamps.

Auf diese Weise wird die geforderte galvanische Trennung erzielt, wobei der Signalmast durch das Hüllelement, wie z.B. zwei zusammensteckbare Halbrohre aus Kunststoff, besonders im seinem oberen Teil des höhenverstellbaren Bauteil vollständig gegen Erdreich und Gleisschotter abgeschirmt ist. Zudem ist auch der höhenverstellbare Teil durch die Isolierschicht und die Isolierelemente vollständig gegenüber dem Fussteil isoliert, so dass der Signalkopf selbst auf dem Potential der Zuführungsleitungen für die elektrische Versorgung der Signalleuchten liegt und sowohl gegen die Bauwerkerde als auch gegen die Bahnerde abgeschirmt ist.In this way, the required galvanic isolation is achieved, with the signal mast through the envelope element, e.g. two pluggable half-pipes made of plastic, especially in its upper part of the height-adjustable component is completely shielded from the ground and ballast. In addition, the height-adjustable part is completely insulated from the foot part by the insulating layer and the insulating elements, so that the signal head itself is at the potential of the supply lines for the electrical supply of the signal lights and is shielded both against the building earth and against the railway earth.

Da der Aufsteller des Lichtsignals aufgrund der Höhenverstellbarkeit des zweiteiligen Signalmasts vergleichsweise flexibel hinsichtlich der Höhe der Anordnung des Signalkopfes und ebenfalls weitgehend flexibel bezüglich der Einbautiefe des Signalmasts im Erdreich und/oder im Gleisschotter ist, kann der Signalkopf in Bodennähe angeordnet werden, wodurch das Lichtsignal als Zwergsignal einsetzbar ist.Since the display of the light signal is comparatively flexible with regard to the height of the arrangement of the signal head due to the height adjustability of the two-part signal mast and also largely flexible with regard to the installation depth of the signal mast in the ground and / or in the ballast, the signal head can be arranged near the ground, making the light signal as Dwarf signal can be used.

Zur Erzielung einer guten Stabilität von Fussteil und höhenverstellbarem Teil kann der höhenverstellbare Teil teleskop-artig ausziehbar gestaltet sein. So kann der höhenverstellbare Teil beispielsweise auf entsprechenden Isolierschichten in den Führungen des Fussteils gleiten und dann in der gewünschten Stellung fixiert werden.In order to achieve good stability of the foot part and the height-adjustable part, the height-adjustable part can be made telescopically extendable. For example, the height-adjustable part can slide on corresponding insulating layers in the guides of the foot part and then be fixed in the desired position.

Die Erfindung wird nachfolgend anhand der Zeichnung beispielsweise näher erläutert. Dabei zeigen:

Figur 1
eine perspektivische Ansicht eines Zwergsignals mit Hüllrohr links und ohne Hüllrohr rechts; und
Figur 2
eine Frontansicht eines zweiteiligen Signalmasts, auf dem der in Figur 1 gezeigte Signalkopf montierbar ist.
The invention is explained in more detail below with reference to the drawing, for example. Show:
Figure 1
a perspective view of a dwarf signal with cladding tube on the left and without cladding tube on the right; and
Figure 2
a front view of a two-part signal tower on which the in Figure 1 shown signal head is mountable.

Figur 1 zeigt nun in einer perspektivischen Darstellung ein Zwergsignal 2, wie es von einer Vielzahl von Bahnbetreibern in Bodennähe angeordnet verwendet wird. Das Zwergsignal 2 umfasst einen Signalkopf 4, der auf einem zweiteiligen Signalmast 6 ruht. Der Signalkopf 4 weist drei Signalpunkte 8, 10, 12 zur Darstellung von Signalbegriffen, wie FAHRT, VORSICHT, HALT, auf. In der linken Darstellung ist der zweiteilige Signalmast 6 von einem Isolierrohr 14 aus Kunststoff umgeben. Vom Signalmast 6 ist in dieser Darstellung nur ein zum Fussteil 18 gehörender Mastfuss 16 erkennbar. In im Gleisbereich verbauten Zustand wird der Signalmast 6 jedoch fast vollständig im Erdreich und/oder Gleisschotter angeordnet, sodass das Isolierrohr 14 im Besonderen einen höhenverstellbaren Mastteil 20 (vgl. Figur 2) und damit auch den Signalkopf 4 gegen das Erdreich und den Gleisschotter isoliert. Zur einfachen Montage des Isolierrohrs 14 kann dieses aus zwei Halbrohren vor Ort durch Zusammendrücken von Rastnuten erzeugt werden. Figure 1 now shows a perspective view of a dwarf signal 2, as used by a large number of railway operators arranged near the ground. The dwarf signal 2 comprises a signal head 4, which rests on a two-part signal mast 6. The signal head 4 has three signal points 8, 10, 12 for representing signal terms such as DRIVING, CAUTION, STOP. In the illustration on the left, the two-part signal mast 6 is surrounded by an insulating tube 14 made of plastic. In this illustration, only one mast foot 16 belonging to the foot part 18 can be seen from the signal mast 6. When installed in the track area, however, the signal mast 6 is arranged almost completely in the ground and / or track ballast, so that the insulating tube 14 in particular has a height-adjustable mast part 20 (cf. Figure 2 ) and thus also the signal head 4 isolated from the ground and the ballast. For simple assembly of the insulating tube 14, it can be produced from two half-tubes on site by compressing locking grooves.

Figur 2 zeigt nun in einer Vorderansicht den in Figur 1 schon eingeführten Signalmast 6 und dessen zweiteiligen Aufbau, umfassend das Fussteil 18 und den höhenverstellbar anordenbaren Mastteil 20. Der Mastteil 20 weist im oberen Bereich Befestigungslager 22 zur Montage des Signalkopfs 4 auf. Der Mastteil 20 wird in dem Fussteil 18 nach oben und unten bewegt und gleitet dabei auf einer Isolierplatte 24 aus Kunststoff. Bei der Verschraubung von Mastteil 20 mit dem Fussteil 18 werden die Schrauben 26 und die rückseitigen Muttern mit Unterlegscheiben 28 ebenfalls isoliert. Zudem wird auch eine Kunststoffbuchse in das Bohrloch eingesetzt, damit sicher vermieden ist, dass die Schrauben 26 den Mastteil 20 elektrisch mit dem Fussteil 18 verbinden. Figure 2 shows a front view of the in Figure 1 Signal mast 6 already introduced and its two-part structure, comprising the foot part 18 and the height-adjustable mast part 20. The mast part 20 has fastening bearings 22 in the upper region for mounting the signal head 4. The mast part 20 is moved up and down in the foot part 18 and thereby slides on an insulating plate 24 made of plastic. When the mast part 20 is screwed to the foot part 18, the screws 26 and the rear nuts with washers 28 are also insulated. In addition, a plastic bushing is also inserted into the borehole, so that it is reliably avoided that the screws 26 electrically connect the mast part 20 to the foot part 18.

Auf diese Weise wird die geforderte galvanische Trennung erzielt, wobei der Signalmast 6 durch das Hüllrohr 14, wie z.B. zwei zusammensteckbare Halbrohre aus Kunststoff, gegen Erdreich und Gleisschotter abgeschirmt ist. Zudem ist auch der höhenverstellbare Mastteil 20 durch die Isolierschicht 24 und die Isolierelemente 28 vollständig gegenüber dem Fussteil 18 isoliert, so dass der Signalkopf 4 selbst auf dem Potential der hier nicht weiter dargestellten Zuführungsleitungen für die elektrische Versorgung der Signalpunkte 8 bis 12 liegt und sowohl gegen die Bauwerkerde als auch gegen die Bahnerde abgeschirmt ist.In this way, the required galvanic isolation is achieved, the signal mast 6 being shielded from the ground and track ballast by the cladding tube 14, such as two half-tubes made of plastic which can be plugged together. In addition is also the height-adjustable mast part 20 is completely insulated from the foot part 18 by the insulating layer 24 and the insulating elements 28, so that the signal head 4 itself lies at the potential of the supply lines (not shown here) for the electrical supply of the signal points 8 to 12 and both against the building earth as well as being shielded from the railway earth.
