Description

VEHICULE POUR LA CONSTRUCTION ET LA MAINTENANCE DES CATENAIRES VEHICLE FOR THE CONSTRUCTION AND MAINTENANCE OF CATENARIES
La présente invention a trait aux travaux de construction et/ou de maintenance et ou de contrôle de lignes aériennes de traction électrique équipant les réseaux de voies ferrées.The present invention relates to construction work and / or maintenance and or control of overhead electric traction lines equipping railway networks.
L'équipe d'entretien et/ou de contrôle des équipements des voies ferrées utilisent habituellement un échafaudage roulant du type de celui constitué d'une structure mobile susceptible d'être installée sur les deux rails d'une voie ferrée pour travailler à un point au-dessus du sol, afin que le personnel de l'équipe d'entretien puisse assurer des interventions de construction, de maintenance et de contrôle des lignes aériennes de traction électrique suspendues équipant les réseaux des voies ferrées. Cet échafaudage se compose généralement d'un socle monté roulant le long des deux rails d'une voie ferrée et servant d'embase-support à une structure formée de deux échelles permettant d'accéder à leurs extrémités hautes à une plate-forme de travail permettant de réaliser des travaux en "hauteur". Un tel échafaudage de structure légère a pour but principal de pouvoir, suivant les besoins, évoluer le long des deux rails de la voie ferrée tout en pouvant être retiré temporairement et manuellement (par portage) de ladite voie, pour laisser passer le trafic normal.The railway equipment maintenance and / or control team usually uses a rolling scaffold of the type consisting of a mobile structure capable of being installed on the two rails of a railway to work at a point. above the ground, so that the maintenance team personnel can carry out construction, maintenance and control work on the overhead electric traction lines fitted to the railway networks. This scaffolding generally consists of a pedestal mounted rolling along the two rails of a railroad track and serving as a support base for a structure formed by two ladders giving access to their upper ends to a working platform allowing work to be carried out at height. The main purpose of such scaffolding with a light structure is to be able to move along the two rails of the track, as required, while being able to be removed temporarily and manually (by porting) from said track, to allow normal traffic to pass.
L'équipe d'entretien utilise aussi des wagons-nacelles qui, quant à eux, sont très lourds d'intervention car ils nécessitent la sortie de locotracteurs et de wagons entraînant des temps d'acheminement et de dégagement importants. L'équipe d'entretien est souvent amenée à contrôler également la hauteur et le désaxement des fils de contact des lignes aériennes de traction électrique sur voies ferrées, par rapport au plan des rails. Elle utilise pour ce faire, un véhicule de contrôle du type de celui décrit dans la demande de brevet français n°2.677.941 au nom de la demanderesse. Un tel véhicule est constitué par une plate-forme ferroviaire montée sur un châssis roulant et sur laquelle est suspendu un instrument de mesure qui, équipé à sa partie haute d'une traverse de mesure et à sa partie basse d'un train de roulement sur rails, est monté mobile librement par rapport à ladite plate-forme pour évoluer entre une position haute dite escamotée où le train de roulement est désolidarisé des deux rails, et une position basse dite de mesure où le train de roulement repose sur lesdits rails. L'intérêt d'un tel véhicule en deux parties indépendantes, plate-forme et instument de mesure, est d'autoriser une mobilité dudit instrument par rapport au plan de référence desdits rails, indépendamment de celui de la plate-forme ferroviaire. Cette dernière sert donc de châssis-porteur audit instrument et ne définit en rien un plan de référence pour la mesure de la hauteur et du désaxement des fils de contact, dès lors qu'en position de mesure, ledit instrument ne repose sur les rails que par son propre train de roulement. Faisant le bilan de cet état de fait et d'un cahier des charges préétabli, la demanderesse a mené des recherches qui ont abouti à la réalisation d'un nouveau concept de véhicule spécialement étudié pour la construction et/ou pour la maintenance et/ou pour le contrôle de lignes aériennes de traction électrique équipant les réseaux de voies ferrées.The maintenance team also uses bucket wagons which, in turn, are very heavy intervention because they require the exit of locomotive and wagons resulting in significant routing and clearance times. The maintenance team is often called upon to also control the height and the misalignment of the contact wires of overhead electric traction lines on railways, relative to the plane of the rails. To do this, it uses a control vehicle of the type described in French patent application no. 2,677,941 in the name of the applicant. Such a vehicle is constituted by a railway platform mounted on a rolling chassis and on which hangs a measuring instrument which, equipped at its upper part with a measuring cross member and at its lower part with a running gear on rails, is mounted to move freely relative to said platform in order to move between a so-called retracted high position where the undercarriage is separated from the two rails, and a so-called low measurement position where the undercarriage rests on said rails. The advantage of such a vehicle in two independent parts, platform and measuring instrument, is to allow mobility of said instrument relative to the reference plane of said rails, independently of that of the railway platform. The latter therefore serves as a supporting frame for said instrument and in no way defines a reference plane for measuring the height and the offset of the contact wires, since in the measurement position, said instrument only rests on the rails by its own undercarriage. Taking stock of this state of affairs and of a pre-established specification, the plaintiff has carried out research which has led to the production of a new concept of vehicle specially studied for construction and / or for maintenance and / or for the control of overhead electric traction lines fitted to railway networks.
Suivant l'invention, ce véhicule est constitué d'un châssis roulant automoteur sur lequel une plate-forme élévatrice et une nacelle élévatrice sont agencées dans le sens longitudinal du véhicule et de part et d'autre d'un instrument de mesure de la hauteur et du désaxement du ou des fils de contact des lignes aériennes de traction électrique sur voies ferrées, lequel instrument est monté mobile indépendamment dudit châssis.According to the invention, this vehicle consists of a self-propelled chassis on which an elevating platform and a lifting nacelle are arranged in the longitudinal direction of the vehicle and on either side of a height measuring instrument and the misalignment of the contact wire or wires of overhead electric traction lines on railways, which instrument is mounted movable independently of said chassis.
Un tel véhicule offre de nombreux avantages, et notamment celui de réunir sur un seul et même châssis roulant autonome - une plate-forme, une nacelle et un instrument de mesure - permettant de réaliser tous travaux de construction, de maintenance ou de contrôle des lignes aériennes de traction électrique, que nécessitent les réseaux de voies ferrées.Such a vehicle offers numerous advantages, and in particular that of bringing together on a single autonomous rolling chassis - a platform, a nacelle and a measuring instrument - making it possible to carry out all construction, maintenance or line control work. overhead electric traction, required by rail networks.
La plate-forme élévatrice qui est avantageusement extensible en longueur de part et d'autre de l'axe médian vertical de la voie ferrée de sorte à pouvoir augmenter virtuellement le chemin de déplacement latéral de la personne de l'équipe d'entretien installée dessus, est montée sur un bâti déployable et rétractable en longueur sous l'effet d'au moins un vérin afin d'adapter la hauteur de la plate-forme à la hauteur de travail de la personne oeuvrant dessus.The lifting platform which is advantageously extendable in length on either side of the vertical median axis of the track so as to be able to virtually increase the lateral movement path of the person from the maintenance team installed on it , is mounted on a deployable and retractable frame in length under the effect of at least one jack in order to adapt the height of the platform to the working height of the person working on it.
La nacelle élévatrice, montée également sur un bâti déployable et rétractable en longueur indépendamment des mouvements de la plate-forme élévatrice, peut aussi évoluer en hauteur, de sorte que deux personnes d'une équipe d'entretien installées l'une sur la plate-forme et l'autre sur la nacelle peuvent, à partir du même véhicule, travailler individuellement et selon deux hauteurs différentes.The lifting platform, also mounted on a deployable and retractable frame in length independently of the movements of the lifting platform, can also evolve in height, so that two people from a maintenance team installed one on the platform. form and the other on the nacelle can, from the same vehicle, work individually and at two different heights.
Selon un mode de réalisation préférée de l'invention, la susdite nacelle est associée à la tête d'un mât télescopique dont le piètement est monté articulé sur le susdit châssis, par rapport à l'axe médian vertical de la voie ferrée. Cette possibilité de dévers de la nacelle par rapport audit plan médian vertical, autorisée par un mouvement de basculement du mât et commandée à l'aide d'un vérin à double tige, permet avantageusement d'élever la nacelle au-dessus des fils de contact de la suspension caténaire offrant ainsi au personnel la réalisation d'un travail au-dessus desdits fils de contact Avantageusement, ce châssis roulant est automoteur donnant au véhicule une autonomie de circulation le long de la voie ferrée.According to a preferred embodiment of the invention, the aforesaid nacelle is associated with the head of a telescopic mast, the base of which is articulated on the above-mentioned chassis, relative to the vertical median axis of the railway. This possibility of canting the nacelle relative to said vertical median plane, authorized by a tilting movement of the mast and controlled by means of a double rod jack, advantageously makes it possible to raise the nacelle above the contact wires. of the catenary suspension thus offering to the staff the realization of a work above the said contact wires Advantageously, this rolling chassis is self-propelled giving the vehicle an autonomy of circulation along the railway track.
D'autre part, ce véhicule, de conception plus lourde que l'échafaudage roulant du type "LORRY" et plus légère que celle des wagons-nacelles, est équipé d'un système de déraillement permettant de le retirer temporairement et rapidement de la voie pour laisser passer le trafic ferroviaire normal. Un tel système est constitué généralement d'un dispositif pour abaisser et pour soulever des mécanismes de déplacement auxiliaires ainsi que de deux rails auxilaires s'étendant transversalement au sens longitudinal dudit véhicule. Ainsi, en disposant les rails auxiliaires transversaux à ceux de la voie ferrée et en actionnant le dispositif d'abaissement des roues auxilaires, le véhicule est désolidarisé de sa portance sur les rails de la voie ferrée principale et peut être, à l'aide d'un moyen d'entraînement moteur approprié, déposé sur l'un des côtés de la voie ferrée ou sur une voie parallèle pour dégager la voie principale et autoriser le passage des trains.On the other hand, this vehicle, of a heavier design than rolling scaffolding of the "LORRY" type and lighter than that of gondola cars, is equipped with a derailment system allowing it to be removed temporarily and quickly from the track. to pass normal rail traffic. Such a system generally consists of a device for lowering and lifting auxiliary movement mechanisms as well as two auxiliary rails extending transversely to the longitudinal direction of said vehicle. Thus, by arranging the auxiliary rails transverse to those of the railway track and by actuating the lowering device of the auxiliary wheels, the vehicle is detached from its bearing capacity on the rails of the main railway track and can be, using '' a suitable motor drive means, deposited on one of the sides of the railway or on a parallel track to clear the main track and allow the passage of trains.
Suivant l'invention, le susdit châssis-roulant est équipé sur ses bords avant et arrière des susdits moyens de mécanismes auxilaires (constitué par les roues de translation et de surélévation du véhicule par rapport aux rails de la voie principale) et sur ses bords longitudinaux, de deux passerelles permettant de ranger les deux rails auxiliaires ainsi qu'un bâti surélévateur du dispositif de déraillement utilisable lorsque ledit véhicule est déposé sur un emplacement latéral situé en contrebas de la voie principale.According to the invention, the aforesaid rolling chassis is equipped on its front and rear edges with the above means of auxiliary mechanisms (constituted by the wheels for translation and elevation of the vehicle relative to the rails of the main track) and on its longitudinal edges , two gangways for storing the two auxiliary rails as well as a raised frame for the derailment device usable when said vehicle is deposited on a lateral location located below the main track.
On comprend que le véhicule pour la construction, pour la maintenance et/ou pour le contrôle des lignes aériennes qui a été ci-dessus décrit offre de nombreuses possibilités et parmi celles-ci :It is understood that the vehicle for the construction, for the maintenance and / or for the control of the overhead lines which has been described above offers many possibilities and among these:
- une autonomie d'évolution le long de la voie ferrée offerte par son châssis roulant auto¬ moteur,- an autonomy of evolution along the railway offered by its self-driving chassis,
- un travail à des niveaux différents pour deux personnes, offert par la présence de la nacelle élévatrice et de la plateforme élévatrice mobiles, indépendamment l'une de l'autre, - un travail en dévers au-dessous et au-dessus des fils de contact offert par la liberté de mouvement de basculement du mât de la nacelle élévatrice par rapport au châssis,- work at different levels for two people, offered by the presence of the lifting platform and the mobile lifting platform, independently of each other, - work on a slope below and above the wires of contact offered by the free movement of tilting of the mast of the lifting platform relative to the chassis,
- la faculté de réaliser, pendant l'évolution du véhicule le long des rails, les opérations de mesure de la hauteur et du désaxement des fils de contact des suspensions caténaires,- the ability to carry out, during the evolution of the vehicle along the rails, the operations of measuring the height and the offset of the contact wires of the catenary suspensions,
- le garage du véhicule sur le bas côté de la voie ferrée pour laisser libre la circulation de la voie principale en dehors des travaux de construction, de maintenance et de contrôle,- the vehicle garage on the side of the railway to allow free circulation of the main track outside of construction, maintenance and control work,
- etc...- etc ...
Les concepts fondamentaux de l'invention venant d'être évoqués ci-dessus, d'autres caractéristiques et d'autres avantages de l'invention ressortiront plus clairement à la lecture de la description qui suit, donnant à titre d'exemple non limitatif et en regard des dessins annexés, un mode de réalisation d'un véhicule pour la construction et/ou pour la maintenance et/ou pour le contrôle de lignes aériennes de traction électrique respectant de tels concepts.The fundamental concepts of the invention having just been mentioned above, other characteristics and other advantages of the invention will emerge more clearly on reading the description which follows, giving by way of nonlimiting example and with reference to the appended drawings, an embodiment of a vehicle for the construction and / or for the maintenance and / or for the control of overhead electric traction lines respecting such concepts.

Tel que représenté sur les dessins des figures 1, 2 et 3, le véhicule de l'invention est constitué d'un châssis 10, équipé d'un train de roulement 11 permettant d'installer le châssis sur les deux rails la et Ib d'une voie ferrée. Ce train de roulement 11 est animé d'une force automotrice hydraulique pour autoriser le cheminement enAs shown in the drawings of Figures 1, 2 and 3, the vehicle of the invention consists of a chassis 10, equipped with a running gear 11 for installing the chassis on the two rails la and Ib d 'a railroad track. This undercarriage 11 is driven by a hydraulic self-propelling force to authorize the travel in
"translation" le long de la voie ferrée, comme le montre la flèche A. Un système de freinage équipe également ce train de roulement 11 afin de pouvoir bloquer l'ensemble du véhicule sur une position déterminée de la voie ferrée, notamment lorsqu'il est en service et travaille en "hauteur"."translation" along the railway, as shown by arrow A. A system of braking also equips this undercarriage 11 in order to be able to block the entire vehicle in a determined position of the railway track, in particular when it is in service and working at "height".
Le châssislO est constitué par un ensemble de longerons judicieusement agencés entre eux de manière à définir une structure logique à trois organes fonctionnels indépendants équipant un tel véhicule.The frame is made up of a set of beams judiciously arranged between them so as to define a logical structure with three independent functional members equipping such a vehicle.
Le premier de ces organes, est constitué par une plate-forme élévatrice 20 montée sur un bâti 21 et variable en longueur (flèche à double sens PI) de sorte qu'en position dite rétractée, telle qu'illustrée sur le dessin de la figure 1, la plate-forme 20 soit à une position basse c'est-à-dire au niveau le plus bas par rapport au plan de la voie ferrée et qu'en position déployée, telle qu'illustrée sur le dessin des figures 1 et 2, la plate-forme soit à un niveau plus élevé. Afin d'assurer les mouvements ascendant et descendant de la plate-forme élévatrice 20, le bâti 21 est constitué de deux mâts télescopiques dont les déploiements ou les rétractions sont commandés sous l'effet d'un vérin non représenté. La plate-forme 20 destinée à porter une personne de l'équipe d'entretien afin d'assurer des travaux d'intervention en hauteur sur les lignes aériennes de traction électrique est également, selon une caractéristique particulièrement avantageuse de l'invention, extensible en longueur comme le montre la flèche P2 sur le dessin de la figure 3. De la sorte, le plateau de la plate-forme 20, habillée extérieurement d'un garde-corps de protection, permet d'augmenter les déplacements latéraux du personnel en débordement du véhicule lorsque ladite plate-forme est en position de travail. En position de repos, notamment lorsque le bâti 21 est en position rétractée, les ralonges du plateau de la plate¬ forme 20 peuvent être repliées vers l'intérieur afin de limiter l'encombrement du véhicule lorsque il est en circulation (flèche A) sur la voie ferrée. Le deuxième organe est constitué par une nacelle élévatrice 30 montée à l'extrémité haute d'un mât réglable en longueur, comme le montre la flèche à double sens NI. Le déploiement et/ou la rétraction de ce mât 31 commandé par un vérin, indépendamment de la commande des mouvements de déploiement et de rétraction du bâti 21 de la plate-forme 20, permet d'élever et ou d'abaisser respectivement la nacelle 30 par rapport au véhicule auquel elle est associée. L'avantage d'une commande indépendante des mouvements PI de la plate-forme 20 et des mouvements NI de la nacelle 30 est de permettre aux personnes installées sur leur plateau respectif, de travailler à des hauteurs différentes, et ce à partir d'un même véhicule. Selon une caractéristique particulièrement avantageuse de l'invention, le piètement du mât 31 est monté articulé (flèche à double sens N2) sur le châssis 10, comme montré sur le dessin de la figure 3. Ces mouvements de basculement N2 du mât 31, commandés à l'aide d'un vérin à double tige, permettent de désaxer la nacelle de part et d'autre de l'axe médian vertical de la voie ferrée sur lequel le véhicule est installé. Cette configuration a l'avantage d'autoriser une élévation de la nacelle 30 au-dessus du fil de contact de la suspension caténaire ou encore de rattraper un plan de travail horizontal pour le plateau de la nacelle 30, lorsque le plan de référence passant par les deux rails la et Ib est en dévers. Le troisième organe, disposé entre la plate-forme élévatrice 20 et la nacelle élévatrice 30, est constitué d'un instrument 40 aménagé notamment d'une traverse de mesure 41 parallèle à un plan de référence passant par les deux rails la, Ib pour mesurer la hauteur du fil de contact par rapport audit plan de référence et le désaxement dudit fil par rapport à un point milieu de référence figurant l'axe du matériel roulant évoluant normalement sur les deux rails la et Ib. Cet instrument, du type de celui décrit dans la demande de brevet français numéro 2.677.941 au nom de la demanderesse est du type de celui qui est équipé à sa partie haute de la susdite traverse de mesure 41 et à sa partie basse d'un train de roulement sur rails 42 constitué de deux galets épaulés prenant référence sur un rail ou sur l'autre, mais de telle sorte que lesdits galets ne soient jamais en contact horizontal avec les rails. Une telle configuration est prise en compte dans l'étalonnage de la traverse de mesure. La partie mobile de l'instrument est montée suspendue à la partie fixe solidaire du cassis roulant au moyen de galets et , en cas de dévers, la prise de référence sur l'un des rails la ou Ib est figée par des ressorts à extension..The first of these organs, is constituted by a lifting platform 20 mounted on a frame 21 and variable in length (two-way arrow PI) so that in the so-called retracted position, as illustrated in the drawing of the figure 1, the platform 20 is in a low position, that is to say at the lowest level with respect to the plane of the railway and in the deployed position, as illustrated in the drawing of FIGS. 1 and 2, the platform is at a higher level. In order to ensure the upward and downward movements of the lifting platform 20, the frame 21 consists of two telescopic masts whose deployments or retractions are controlled under the effect of a jack not shown. The platform 20 intended to carry a person from the maintenance team in order to carry out intervention work at height on the overhead electric traction lines is also, according to a particularly advantageous characteristic of the invention, extensible in length as shown by the arrow P2 in the drawing of FIG. 3. In this way, the platform of the platform 20, dressed externally with a protective railing, makes it possible to increase the lateral displacements of the personnel in overflow of the vehicle when said platform is in the working position. In the rest position, in particular when the frame 21 is in the retracted position, the extensions of the platform of the platform 20 can be folded inwards in order to limit the size of the vehicle when it is in circulation (arrow A) on the railway. The second member consists of a lifting platform 30 mounted at the top end of a mast adjustable in length, as shown by the two-way arrow NI. The deployment and / or retraction of this mast 31 controlled by a jack, independently of the control of the deployment and retraction movements of the frame 21 of the platform 20, makes it possible to raise and / or lower the nacelle 30 respectively relative to the vehicle with which it is associated. The advantage of independent control of the PI movements of the platform 20 and the NI movements of the nacelle 30 is that it allows people installed on their respective platforms to work at different heights, starting from a same vehicle. According to a particularly advantageous characteristic of the invention, the base of the mast 31 is mounted articulated (two-way arrow N2) on the chassis 10, as shown in the drawing in FIG. 3. These tilting movements N2 of the mast 31, controlled using a double rod cylinder, offset the nacelle on either side of the vertical median axis of the railway on which the vehicle is installed. This configuration has the advantage of authorizing an elevation of the nacelle 30 above the contact wire of the catenary suspension or even catching up with a horizontal work plan for the platform of the nacelle 30, when the reference plane passing through the two rails 1a and 1b are on a slope. The third member, disposed between the lifting platform 20 and the lifting platform 30, consists of an instrument 40 fitted in particular with a measuring crosspiece 41 parallel to a reference plane passing through the two rails 1a, 1b for measuring the height of the contact wire with respect to said reference plane and the offset of said wire with respect to a reference mid-point representing the axis of the rolling stock moving normally on the two rails 1a and 1b. This instrument, of the type described in French patent application number 2,677,941 in the name of the applicant is of the type which is equipped at its upper part with the above-mentioned measuring cross member 41 and at its lower part with a running gear on rails 42 consisting of two shouldered rollers taking reference on one rail or the other, but in such a way that said rollers are never in horizontal contact with the rails. Such a configuration is taken into account in the calibration of the measuring crosspiece. The movable part of the instrument is mounted suspended from the fixed part secured to the rolling blackcurrant by means of rollers and, in the event of a slope, the reference point on one of the rails 1a or 1b is fixed by extension springs. .
L'avantage de disposer en ligne la plate-forme élévatrice 20, l'instrument de mesure 40 et la nacelle élévatrice 40 est de pouvoir contrôler l'instrument de mesure 40 soit à partir de la plate-forme 20 soit à partir de la nacelle 30. En outre, cette prédisposition en ligne dans l'axe longitudinal du châssis, limite considérablement l'encombrement occupé par les trois organes 20, 30 et 40, permettant ainsi d'avoir un véhicule automoteur multifonctionnel et d'un poids peu élevé. Deux échelles d'accès 12 et 13 sont installées sur le châssis roulant 10 sur les bords avant et arrière de ce dernier, ces échelles ont pour objet de permettre au personnel de l'équipe d'entretien d'accéder à la nacelle 20 et à la plate-forme 30, respectivement.The advantage of having the elevating platform 20, the measuring instrument 40 and the lifting platform 40 in line is being able to control the measuring instrument 40 either from the platform 20 or from the platform 30. In addition, this predisposition in line in the longitudinal axis of the chassis, considerably limits the space occupied by the three members 20, 30 and 40, thus making it possible to have a multifunctional self-propelled vehicle of low weight. Two access ladders 12 and 13 are installed on the rolling chassis 10 on the front and rear edges of the latter, these ladders are intended to allow the personnel of the maintenance team to access the nacelle 20 and platform 30, respectively.
