Description
La présente invention se rapporte au domaine des véhicules ferroviaires et plus particulièrement à celui de la commande du fonctionnement d'un équipement mécanique d'un véhicule ferroviaire, notamment d'un véhicule ferroviaire de transport de marchandises ou de maintenance de voies ferrées.The present invention relates to the field of railway vehicles and more particularly to that of the control of the operation of a mechanical equipment of a rail vehicle, in particular a railway vehicle for the transport of goods or maintenance of railways.
Comme exemple d'un véhicule de maintenance de voies ferrées on peut citer les ballastières, qui sont des wagons servant à transporter du ballast jusqu'à un chantier de voies ferrées et à l'y déposer.An example of a railroad maintenance vehicle is ballast boats, which are railcars used to transport ballast to a railroad yard and drop it off.
Une ballastière comprend à cet effet un corps creux formant des trémies pour le ballast et monté sur des boggies pour circulation sur une voie ferrée, la dépose et la répartition du ballast le long de la voie ferrée s'effectuant par l'intermédiaire d'ouvertures ménagées en partie inférieure des trémies et fermées chacune de manière sélective par une trappe mobile, par exemple une trappe à casque. Une ballastière peut comprendre un nombre quelconque de trappes, mais on prévoit généralement trois trappes de chaque côté du réservoir réparties en une trappe avant, une trappe centrale et une trappe arrière.For this purpose, a ballast tank comprises a hollow body forming hoppers for the ballast and mounted on bogies for circulation on a railway track, the removal and distribution of the ballast along the railway being effected via openings. arranged in the lower part of the hoppers and each closed selectively by a mobile hatch, for example a hatch with a helmet. A ballast tank can include any number of hatches, but there are generally three hatches on each side of the tank divided into a front hatch, a central hatch and a rear hatch.
La répartition du ballast le long d'une voie ferrée est assurée par l'avancée continue mais lente, généralement à environ 5 km/h, d'un train de ballast comportant un nombre quelconque de ballastières, généralement entre trois et vingt-deux, qui sont utilisées les unes après les autres au fur et à mesure de la dépose du ballast.The distribution of the ballast along a railway is ensured by the continuous but slow advance, generally at about 5 km / h, of a ballast train containing any number of ballast boats, generally between three and twenty-two, which are used one after the other as the ballast is removed.
Le fonctionnement de chaque trappe, à savoir ses mouvements d'ouverture et de fermeture, est commandé manuellement par l'un respectif de leviers centralisés sur une plateforme de la ballastière et commandant le fonctionnement des trappes par l'intermédiaire de dispositifs transformant un mouvement de pivotement d'un levier respectivement dans un premier sens et un second sens en un mouvement de la trappe correspondante dans les sens respectivement d'ouverture et de fermeture de ladite trappe.The operation of each hatch, namely its opening and closing movements, is manually controlled by a respective centralized levers on a platform of the ballast and controlling the operation of the hatches via devices transforming a movement of pivoting a lever respectively in a first direction and a second direction in a movement of the corresponding hatch in the opening and closing respectively of said hatch.
Dans un tel cas, les manoeuvres d'ouverture et de fermeture des trappes ainsi que le contrôle de la bonne répartition du ballast sont effectuées par au moins deux opérateurs, un opérateur actionnant manuellement les leviers d'une ballastière tandis qu'un deuxième opérateur marche à côté de la ballastière pour contrôler la dépose du ballast et transmettre les instructions appropriées au premier opérateur.In such a case, the opening and closing maneuvers of the hatches and the control of the good distribution of the ballast are performed by at least two operators, an operator manually operating the levers of a ballast tank while a second operator operates next to the ballast tank to control the removal of the ballast and to transmit the appropriate instructions to the first operator.
Cela pose d'importants problèmes de sécurité pour les opérateurs qui doivent se déplacer sur un sol irrégulier, généralement du ballast lui-même, ainsi que monter et descendre des ballastières en ordre de marche, alors que la voie ferrée adjacente est souvent encore ouverte à la circulation. Ces problèmes sont amplifiés lorsque la dépose du ballast se fait lors d'intempéries ou de nuit, l'éclairage étant la plupart du temps assez faible, car assuré uniquement par des lampes frontales ou des ballons lumineux le long de la voie ferrée.This poses significant safety problems for operators who have to move on uneven ground, usually ballast itself, as well as raising and lowering ballast lines in working order, while the adjacent railway is often still open to traffic. the circulation. These problems are amplified when the ballast is removed during inclement weather or at night, the lighting is usually quite low, because provided only by headlamps or light balloons along the railway.
Par ailleurs, des efforts physiques importants sont demandés aux opérateurs, pour monter et descendre des ballastières et actionner les leviers, ce qui pose d'importants problèmes de pénibilité pour les opérateurs.In addition, considerable physical effort is required of the operators, to move up and down ballast and operate the levers, which poses significant problems of difficulty for operators.
Afin de résoudre les problèmes mentionnés ci-dessus, ont été proposés différents systèmes de mécanisation des trappes faisant intervenir des moteurs ou des vérins placés au niveau du corps de la ballastière et agissant directement sur les trappes, avec commande à distance. Un exemple d'une telle mécanisation est divulgué dans le brevet américain
Il a également été proposé, dans le brevet français
Les systèmes de mécanisation ci-dessus sont en théorie capables de résoudre de manière satisfaisante les problèmes de sécurité et de pénibilité pour les opérateurs.The mechanization systems above are in theory capable of satisfactorily solving the problems of safety and difficulty for the operators.
Toutefois, la mécanisation de la commande des trappes ou des leviers par ces systèmes engendre des coûts relativement importants et nécessitent pour leur installation sur une ballastière d'immobiliser cette dernière pendant une durée conséquente durant laquelle elle ne peut pas être utilisée.However, the mechanization of the control of hatches or levers by these systems generates relatively high costs and require for their installation on a ballast station to immobilize it for a substantial period during which it can not be used.
Par ailleurs, le système de mécanisation doit être choisi ou modifié en fonction de la configuration spécifique de la commande des trappes de la ballastière sur laquelle on souhaite l'installer, ce qui en pratique limite encore l'intérêt de mécaniser la commande des trappes.Furthermore, the mechanization system must be chosen or modified according to the specific configuration of the trap door control of the ballast on which it is desired to install it, which in practice further limits the interest of mechanizing the control of the hatches.
Les inconvénients mentionnés ci-dessus empêchent les systèmes de mécanisation connus de se répandre à l'ensemble du parc de ballastières existantes.The drawbacks mentioned above prevent the known mechanization systems from spreading to the whole of the existing fleet of borrow pits.
Il y a donc un besoin pour un système permettant une mécanisation de la commande des trappes à un coût inférieur, avec une durée réduite d'immobilisation de la ballastière et pour lequel les modifications à lui apporter pour tenir compte de la ballastière sur lequel il doit être installé sont rendues minimales.There is therefore a need for a system allowing mechanization of the hatch control at a lower cost, with a reduced duration of immobilization of the ballast tank and for which the modifications to be made to take into account the ballast on which it must to be installed are made minimal.
La société déposante s'est également aperçue qu'il serait avantageux que les moyens mis en oeuvre dans un tel système de mécanisation ne soient pas limités à la mécanisation de leviers de commande de trappes de ballastière, mais permettent l'actionnement de tout type d'organe de commande, tels que des leviers, des volants, des pédales, etc., qui eux-mêmes commandent tout type d'équipement mécanique de véhicule ferroviaire, tel qu'une trappe de ballastière, un toit ouvrant dans un wagon de transport, etc.The applicant company has also realized that it would be advantageous if the means used in such a mechanization system are not limited to the mechanization of ballast hatch control levers, but allow the actuation of any type of ballast trap. control member, such as levers, flywheels, pedals, etc., which themselves control any type of mechanical equipment of a railway vehicle, such as a bunker hatch, a sunroof in a transport wagon etc.

L'opérateur peut ensuite commander, à l'aide d'une radiocommande, le fonctionnement de chacun des actionneurs 31, pour abaisser ou relever le levier 3 correspondant.The operator can then control, using a radio remote control, the operation of each of the
On constate donc que l'installation du système de mécanisation selon la présente invention est particulièrement aisée et rapide.It is therefore found that the installation of the mechanization system according to the present invention is particularly easy and fast.
Il présente en outre l'avantage essentiel de pouvoir être adapté sur une ballastière existence, sans aucune intervention d'adaptation de cette dernière. La durée d'immobilisation est donc réduite à un minimum, qui correspond seulement au temps nécessaire pour installer un système de mécanisation sur chaque série de trois leviers.It also has the essential advantage of being able to be adapted to a ballasttier existence, without any adaptation intervention of the latter. The Downtime is therefore reduced to a minimum, which corresponds only to the time required to install a mechanization system on each set of three levers.
En d'autres termes, le système de mécanisation selon la présente invention permet, d'une part, de préserver l'intégrité du véhicule ferroviaire, ce qui dans le domaine ferroviaire permet de ne pas avoir de modification substantielle qui engendrerait une procédure contraignante, longue et coûteuse pour obtenir auprès des services administratifs compétents l'agrément d'utilisation du système sur les véhicules, et, d'autre part, de limiter le nombre de systèmes à acquérir et à mettre en place sur l'ensemble du parc de véhicules existants.In other words, the mechanization system according to the present invention makes it possible, on the one hand, to preserve the integrity of the railway vehicle, which in the railroad field makes it possible to have no substantial modification which would give rise to a binding procedure, long and costly to obtain approval for the use of the system on vehicles from the competent administrative services, and secondly to limit the number of systems to be acquired and put in place on the entire fleet of vehicles existing.
Il est bien entendu que les modes de réalisation ci-dessus de la présente invention ont été donnés à titre indicatif et non limitatif et que des modifications pourront y être apportées sans que l'on s'écarte pour autant du cadre de la présente invention.It is understood that the above embodiments of the present invention have been given for information and not limitation and that modifications may be made without departing from the scope of the present invention.
