SISTEMA DI PROTEZIONE PER CAVI DISPOSTI LUNGO LINEEE FERROVIARIE PROTECTION SYSTEM FOR CABLES ARRANGED ALONG RAILWAY LINES
------ ------
La presente invenzione si riferisce ad un sistema di protezione per cavi disposti lungo linee ferroviarie. In particolare la presente invenzione si applica a cavi disposti in cunicoli che scorrono parallelamente ai binari di tal linee. The present invention refers to a protection system for cables arranged along railway lines. In particular, the present invention is applied to cables arranged in tunnels which run parallel to the tracks of such lines.
E’ noto che lungo le linee ferroviarie vi siano molteplici cavi elettrici che scorrono lungo i binari. Tali cavi elettrici portano segnali di vario tipo, ad esempi segnali per i semafori o segnali provenienti dai cosiddetti circuiti di binari, oppure segnali per l’attivazione di scambi. It is known that along the railway lines there are multiple electrical cables that run along the tracks. These electrical cables carry various types of signals, for example signals for traffic lights or signals from so-called track circuits, or signals for the activation of exchanges.
Tali cavi scorrono in cunicoli ricavati lateralmente ai binari sulla massicciata ferroviaria e vengono ricoperti da sabbia in modo da essere protetti da agenti esterni. Sono poi previsti coperchi che ricoprono semplicemente il cunicolo. These cables run in tunnels made laterally to the tracks on the railway embankment and are covered with sand so as to be protected from external agents. Lids are then provided that simply cover the tunnel.
Uno dei problemi più sentiti nell’ambito delle linee elettriche ferroviarie è il furto di cavi in rame. Infatti, il metallo in questione è, dopo l’argento, il migliore che ci sia come conduttore di elettricità, resiste alla corrosione e non è magnetico. One of the most felt problems in the field of railway power lines is the theft of copper cables. In fact, the metal in question is, after silver, the best there is as a conductor of electricity, it resists corrosion and is not magnetic.
L’asporto di tali cavi elettrici posizionati lungo i binari è relativamente semplice in quanto è sufficiente scollegare il cavo alle sue estremità per riuscire a sfilarlo dalla sede di posa. E’ infatti possibile tirare il cavo da uno dei due estremi per prelevarlo con facilità. The removal of these electrical cables positioned along the tracks is relatively simple as it is sufficient to disconnect the cable at its ends to be able to remove it from the installation site. It is in fact possible to pull the cable from one of the two ends to take it out easily.
La presente invenzione si propone di ovviare ai sopracitati inconvenienti proponendo un sistema di protezione che fissa il cavo lungo tali cunicoli, rendendo difficoltoso e improbabile il loro asporto. Un aspetto della presente invenzione riguarda un sistema di protezione per cavi disposti lungo linee ferroviarie avente le caratteristiche della allegata rivendicazione 1. The present invention aims to obviate the aforementioned drawbacks by proposing a protection system that fixes the cable along these tunnels, making their removal difficult and improbable. An aspect of the present invention relates to a protection system for cables arranged along railway lines having the characteristics of the attached claim 1.
Le caratteristiche ed i vantaggi del sistema secondo la presente invenzione saranno meglio chiari ed evidenti dalla descrizione seguente, esemplificativa e non limitativa, di una forma di realizzazione con riferimento alle figure allegate che illustrano rispettivamente: The characteristics and advantages of the system according to the present invention will be better clear and evident from the following, exemplary and non-limiting description of an embodiment with reference to the attached figures which respectively illustrate:
• la figura 1 illustra uno spezzone di cunicolo con un cavo ferroviario alloggiato al suo interno; • figure 1 illustrates a section of tunnel with a railway cable housed inside it;
• la figura 2 illustra una staffetta per il cavo ferroviario secondo la presente invenzione; Figure 2 illustrates a bracket for the railway cable according to the present invention;
• la figura 3 illustra una sezione trasversale del cunicolo con il cavo fissato in esso tramite tale staffetta; Figure 3 shows a cross section of the tunnel with the cable fixed therein by means of this bracket;
• la figura 4 illustra una vista dall’alto del cunicolo con il cavo fissato in esso tramite staffetta bloccata da coperchio e vite sopra il cunicolo. • Figure 4 illustrates a top view of the tunnel with the cable fixed in it by means of a bracket blocked by the cover and screw above the tunnel.
Con riferimento alle citate figure si illustra un cunicolo 2 comprendente una o più sedi conformate a U atte ad ospitare cavi ferroviari ed almeno una gola 3 ricavata a ridosso di una delle spalle del cunicolo, nella quale viene ospitato il cavo C. Un coperchio 4 ricopre completamente il cunicolo. With reference to the aforementioned figures, a tunnel 2 is illustrated comprising one or more U-shaped seats suitable for housing railway cables and at least a groove 3 obtained close to one of the shoulders of the tunnel, in which the cable C is housed. A cover 4 covers the tunnel completely.
Il sistema di protezione per cavi secondo la presente invenzione comprende una staffetta 5 provvista di un occhiello 6 per il fissaggio del cavo al suo interno e mezzi di fissaggio della staffetta stessa al cunicolo che nel contempo fungono da mezzi di fissaggio del coperchio al cunicolo ed alla staffetta stessa. The cable protection system according to the present invention comprises a bracket 5 provided with an eyelet 6 for fixing the cable inside it and means for fixing the bracket itself to the tunnel which at the same time act as means for fixing the cover to the tunnel and to the relay race itself.
La staffetta è sostanzialmente conformata a “U” rovesciata, in modo da potersi innestare, tipo una graffetta, sul ramo di tale U. L’occhiello 6 della staffetta è ricavato su uno dei due lati della U rovesciata. The relay is substantially shaped like an inverted "U", so as to be able to engage, like a paper clip, on the branch of this U. The eyelet 6 of the relay is obtained on one of the two sides of the inverted U.
Le staffette vengono posizionate (aggraffandole sul ramo) lungo i cunicoli a distanze prefissate (ad esempio 1 metro) e fissate ai cavi elettrici nelle gole tramite gli occhielli 6. The brackets are positioned (crimping them on the branch) along the tunnels at predetermined distances (for example 1 meter) and fixed to the electric cables in the grooves using the eyelets 6.
Tali mezzi di fissaggio della staffetta al cunicolo sono realizzati tramite una vite 7 preferibilmente autofilettante per calcestruzzo che si inserisce sul coperchio nella posizione che inferiormente presenta la staffetta. These means for fixing the bracket to the tunnel are made by means of a screw 7 preferably self-tapping for concrete which is inserted on the lid in the position that the bracket has below.
Sulla parte orizzontale 51 della staffetta, è presente un foro 52 che consente il passaggio di tale vite 7. In questo modo, si fissa il coperchio sul ramo del cunicolo e nel contempo si fissa cavo staffetta al cunicolo stesso. On the horizontal part 51 of the bracket, there is a hole 52 which allows the passage of this screw 7. In this way, the cover is fixed on the branch of the tunnel and at the same time the bracket cable is fixed to the tunnel itself.
Lo sfilamento del cavo dai pozzetti di controllo dopo il suo scollegamento diventa difficoltoso se non impossibile in quanto a tratti brevi il cavo stesso è fissato al cunicolo e per asportare il cavo stesso bisognerebbe togliere tutte le staffette togliendo tutte le viti autofilettanti ed infine il coperchio. The unthreading of the cable from the control wells after its disconnection becomes difficult if not impossible as in short stretches the cable itself is fixed to the tunnel and to remove the cable itself all the brackets should be removed by removing all the self-tapping screws and finally the cover.
Vantaggiosamente l’occhiello è svincolabile dalla staffetta, l’unione delle due parti può ad esempio avvenire tramite un convenzionale bullone 8. L’occhiello è vantaggiosamente aperto, per consentire di infilare in esso il cavo C. Alle sue estremità sono previsti due fori 61 nei quali si inserisce il citato bullone 8 che unisce le due estremità fino a chiudere il cavo. Inoltre, l’occhiello è dotato di profili in gomma 9 o simile materiale per ottenere un aggraffaggio delicato del cavo. Advantageously, the eyelet can be released from the bracket, the two parts can be joined for example by means of a conventional bolt 8. The eyelet is advantageously open, to allow cable C to be inserted into it. Two holes 61 are provided at its ends. in which the aforementioned bolt 8 is inserted which joins the two ends to close the cable. In addition, the eyelet is equipped with rubber profiles 9 or similar material to obtain a delicate crimping of the cable.
Preferibilmente, la vite del bullone 8 può essere realizzata di pezzo con la staffetta o può essere collegata ad esso. In questo modo si facilità il fissaggio del cavo nell’occhiello ed alla staffetta stessa. Preferably, the screw of the bolt 8 can be made integrally with the bracket or can be connected to it. This makes it easier to attach the cable to the eyelet and to the bracket itself.
