The chassis may move along the main chassis under the action of a chain driven by a motor so as to advance, during the works, step by step with respect to the track while the machine progresses continuously. The reactions of inertia are compensated by a mobile counterweight coupled to the chain so as to execute movements parallel to those of the mobile chassis but in opposite direction, the respective quantities of movement of the counterweight and of the mobile chassis including the working members being equal and opposite.

Description

L'invention se rapporte à un engin de travaux sur voie ferrée à avancement continu, comprenant un châssis principal doté d'organes de roulement sur la voie et un châssis auxiliaire supportant des organes de travail tels que des groupes de bourrage de ballast et de relevage-ripage de voie, ce dernier châssis étant mobile et pouvant se déplacer en translation le long du châssis principal sous l'action de moyens d'entrainement de façon à avancer, au cours des travaux, pas à pas par rapport à la voie tandis que l'engin progresse de façon continue.The invention relates to a continuously advancing railway work machine, comprising a main chassis provided with running members on the track and an auxiliary chassis supporting working members such as ballast tamping and lifting groups. - track slip, the latter chassis being mobile and being able to move in translation along the main chassis under the action of drive means so as to advance, during the works, step by step relative to the track while the machine progresses continuously.

Un engin de ce genre se caractérise, en fonctionnement, par un avancement continu du châssis principal auquel se superpose un avancement discontinu du châssis mobile supportant les organes de travail. Ce dernier doit en effet, dans le cas notamment d'une machine à bourrer la voie, démarrer, freiner et s'arrêter à chaque cycle de travail, sur un trajet de déplacement relativement court déterminé par exemple par un intervalle de 50 à 60 cm entre,les traverses de la voie.A machine of this kind is characterized, in operation, by a continuous advancement of the main chassis on which is superimposed a discontinuous advancement of the movable chassis supporting the working members. The latter must in fact, in the case in particular of a track-stuffing machine, start, brake and stop at each work cycle, on a relatively short travel path determined for example by an interval of 50 to 60 cm. between, the sleepers of the track.

On connaît déjà des bourreuses de voies ferrées conçues à cet effet, dans lesquelles le châssis mobile porteur des organes de bourrage et de relevage-ripage est réalisé à partir d'un châssis reposant à l'arrière sur un essieu circulant sur les rails entre les organes de roulement du châssis principal de la bourreuse. Ce châssis est muni à sa partie avant de deux timons coulissant par rapport au châssis principal dans des dispositifs de guidage appropriés. Le châssis mobile est accéléré et freiné à chaque cycle de travail par un vérin longitudinal, solidaire à une extrémité du châssis mobile et à l'autre extrémité du châssis principal de la bourreuse.Railroad tamping machines designed for this purpose are already known, in which the mobile chassis carrying the tamping and lifting-shifting members is produced from a chassis resting on the rear on an axle running on the rails between the running gear of the main tamping frame. This chassis is provided at its front part with two drawbars sliding relative to the main chassis in suitable guide devices. The mobile chassis is accelerated and braked at each work cycle by a longitudinal cylinder, secured at one end of the mobile chassis and at the other end of the main chassis of the tamping machine.

Une bourreuse conçue selon ce principe permet d'obtenir une augmentation sensible du rendement en travail par rapport aux bourreuses dans lesquelles les organes de travail sont fixes par rapport au châssis principal et exigent donc, pour leur déplacement de traverse en traverse, l'accélération et le freinage de l'ensemble de la machine.A tamping machine designed according to this principle makes it possible to obtain a significant increase in the working yield compared to tamping machines in which the working members are fixed relative to the main chassis and therefore require, for their movement from cross to cross, the acceleration and braking of the whole machine.

Les bourreuses à avancement continu permettent, dans la phase de déplacement de traverse en traverse des organes de travail, de s'affranchir des conditions d'adhérence roues-rails et, en conséquence, de diminuer notablement la durée de cette phase, puisque les efforts d'accélération ou de décélération des organes de travail ne sont plus à transmettre sous la forme de couples moteurs agissant sur les roues de la machine circulant sur les rails. Les systèmes de translation des groupes de travail, caractérisant ce type de bourreuse, permettent en effet d'imprimer aux groupes de travail des efforts de traction et de freinage beaucoup plus élevés.Continuously advancing tamping machines make it possible, during the transverse displacement phase to transverse of the working members, to overcome the conditions of wheel-rail adhesion and, consequently, to significantly reduce the duration of this phase, since the forces acceleration or deceleration of the working members are no longer to be transmitted in the form of engine torques acting on the wheels of the machine traveling on the rails. The translation systems of the working groups, which characterize this type of tamping machine, make it possible to impart much higher traction and braking forces to the working groups.

Un problème particulier à ce type de bourreuse à avancement continu réside cependant dans le compromis qu'il est nécessaire de trouver entre l'augmentation de rendement rendue théoriquement possible par le principe énoncé ci-dessus d'un châssis support des organes de travail en mouvement relatif par rapport au châssis principal de l'engin, et le confort du peronnel de conduite, situé dans les cabines solidaires du châssis principal.A particular problem with this type of tamping machine with continuous advancement however lies in the compromise that it is necessary to find between the increase in yield theoretically made possible by the principle stated above of a chassis supporting the working members in motion. relative to the main chassis of the machine, and the comfort of the driving staff, located in cabins integral with the main chassis.

Les accélérations et décélérations du châssis mobile supportant les organes de travail qui apparaissent à chaque cycle de travail se traduisent, compte tenu du poids non négligeable de ce châssis mobile, par des réactions d'inertie longitudinales, se répercutant sur le châssis principal de la bourreuse et imprimant aux conducteurs situés dans les cabines des secousses importantes au début et à la fin de la phase déplacement. L'inconfort qui en résulte est d'autant plus sensible que l'on cherche à augmenter davantage le rendement de la bourreuse en accroissant la vitesse de déplacement du châssis mobile. Un autre effet de ces réactions d'inertie se manifeste dans une perte d'adhérence du châssis principal roulant sur les rails au moment où elles apparaissent. Cela nécessite en pratique de donner au châssis principal une charge motrice adhérente la plus élevée possible et conduit donc à des dépenses plus élevées au niveau de l'entraînement de l'engin.The accelerations and decelerations of the mobile chassis supporting the working members which appear at each work cycle are reflected, taking into account the significant weight of this mobile chassis, by longitudinal inertia reactions, which have repercussions on the main chassis of the tamping machine. and printing to the conductors located in the cabins significant tremors at the beginning and at the end of the displacement phase. The resulting discomfort is all the more noticeable when one seeks to further increase the yield of the tamping machine by increasing the speed of movement of the mobile chassis. Another effect of these inertia reactions is manifested in a loss of adhesion of the main chassis rolling on the rails at the moment when they appear. This in practice requires giving the main chassis the highest possible traction load and therefore leads to higher costs in terms of driving the machine.

La présente invention se propose de fournir un engin à avancement continu, du type décrit ci-dessus, pour lequel les réactions d'inertie engendrées par les déplacements discontinus des organes de travail soient éliminées, de façon que l'augmentation de rendement en travail ne soit plus limitée par un inconfort croissant du personnel de conduite.The present invention proposes to provide a machine for continuous advancement, of the type described above, for which the inertia reactions generated by the discontinuous movements of the working members are eliminated, so that the increase in work efficiency is no longer limited by increasing discomfort of the personnel of conduct.

L'invention réside dans le fait qu'un engin du genre considéré comprend en outre un contrepoids mobile, qui est couplé aux moyens d'entraînement du châssis mobile de façon à exécuter des mouvements de translation parallèles à ceux du châssis mobile mais de sens contraire, les quantités de mouvement respectives du contrepoids et du châssis mobile y compris ses organes de travail étant égales et opposées. Autrement dit, les vecteurs quantités de mouvement de ces éléments mobiles sont antiparallèles.The invention resides in the fact that a machine of the type under consideration further comprises a mobile counterweight, which is coupled to the drive means of the mobile chassis so as to execute translational movements parallel to those of the mobile chassis but in the opposite direction. , the respective amounts of movement of the counterweight and of the mobile chassis including its working members being equal and opposite. In other words, the momentum vectors of these mobile elements are antiparallel.

Les réactions d'inertie du châssis mobile et du contrepoids mobile, égales et opposées, s'annulent en permenence, faisant ainsi disparaître toute sensation d'inconfort pour le personnel de conduite situé dans les cabines. Le rendement de l'engin peut, en conséquence, être augmenté par réduction du temps d'avancement pas à pas du châssis mobile et de ses organes de travail.The inertia reactions of the mobile chassis and the mobile counterweight, equal and opposite, cancel each other out permanently, thus eliminating any feeling of discomfort for the driving staff located in the cabins. The efficiency of the machine can therefore be increased by reducing the step-by-step advancement time of the mobile chassis and its working members.

Il convient que les centres de gravité respectifs du contrepoids et du châssis mobile y compris les organes de travail se déplacent sur des droites parallèles aussi rapprochées que possible, afin de minimiser les couples de tangage s'exerçant sur le châssis principal.The respective centers of gravity of the counterweight and of the mobile chassis, including the working members, should move on parallel lines as close together as possible, in order to minimize the torques on the main chassis.

Dans le cas le plus simple, on donnera au contrepoids une masse égale à la masse totale du châssis mobile et des organes qu'il supporte, sa vitesse de translation étant égale en module à celle du châssis mobile. Dans le but de réduire la masse totale de l'engin, on peut aussi donner au contrepoids une masse inférieure à la masse totale du châssis mobile et des organes qu'il supporte; sa vitesse de translation doit alors être supérieure en module à celle du châssis mobile, les modules des vitesses étant dans le rapport inverse des masses.In the simplest case, the counterweight will be given a mass equal to the total mass of the mobile chassis and of the members that it supports, its translation speed being equal in module to that of the mobile chassis. In order to reduce the total mass of the machine, it is also possible to give the counterweight a mass less than the total mass of the mobile chassis and of the members that it supports; its translation speed must then be higher in module than that of the mobile chassis, the speed modules being in the inverse mass ratio.

Le contrepoids et le châssis mobile peuvent être actionnés en translation par un moyen moteur commun et être couplés entre eux par un moyen d'accouplement mécanique. Dans une forme d'exécution relative au cas où le châssis mobile, y compris les organes qu'il supporte, et le contrepoids ont une masse égale, ce moyen d'accouplement peut être consitué par une chaîne entraînée par un moteur commun et formant une boucle fermée à deux brins parallèles à la direction de déplacement du châssis mobile et du contrepoids, chacun de ces derniers étant couplé mécaniquement à l'un respectif desdits brins.Counterweight and movable frame can be operated in translation by a common motor means and be coupled together by a mechanical coupling means. In an embodiment relating to the case where the movable frame, including the members which it supports, and the counterweight have an equal mass, this coupling means can be constituted by a chain driven by a common motor and forming a closed loop with two strands parallel to the direction of movement of the movable frame and the counterweight, each of the latter being mechanically coupled to a respective one of said strands.

Le contrepoids et le châssis mobile peuvent aussi être actionnés en translation par des moyens moteurs distincts et être couplés par des moyens de synchronisation. Ces moyens moteurs sont avantageusement des organes d'actionnement hydrauliques, couplés par des moyens de synchronisation électro-hydrauliques.The counterweight and the movable chassis can also be actuated in translation by separate motor means and be coupled by synchronization means. These motor means are advantageously hydraulic actuating members, coupled by electro-hydraulic synchronization means.

L'un de ces pignons est doté d'un groupe moto-réducteur hydraulique 36 d'entraînement en rotation.The movable frame 25 is coupled by a drive 30 to the lower strand 31a of an endless chain 31 which extends horizontally in the median plane of the main frame 1 between two idler gears 32, 33 with fixed horizontal axes 34, 35 compared to the main chassis. One of these pinions is provided with a hydraulic gear motor group 36 for rotational drive.

Les opérations de relevage-ripage de la voie 2, destinées à éliminer les défauts d'alignement qu'elle peut présenter, sont pilotées par un ensemble de nivellement dont est équipé l'engin, qui comprend un fil 43 tendu entre les sommets de deux tiges verticales 44, 45 largement espacées, reposant sur la voie par des roulettes 46, 47. Entre celles-ci est disposé un chariot palpeur de voie 48 supportant une tige verticale 49 au sommet de laquelle est placé un capteur de déplacement 50 qui, en fonction de la position qu'il prend par rapport au fil 43, asservit en nivellement les groupes de relevage-ripage 13. Un autre ensemble analogue assure l'asservissement latéral relatif aux corrections de tracé de la voie.The lift-shift operations of track 2, intended to eliminate the misalignments which it may have, are controlled by a leveling assembly with which the machine is equipped, which comprises a wire 43 stretched between the tops of two vertical rods 44, 45 widely spaced, resting on the track by wheels 46, 47. Between them is disposed a track feeler carriage 48 supporting a vertical rod 49 at the top of which is placed a displacement sensor 50 which, depending on the position it takes relative to the wire 43, controls the leveling-shifting groups 13 in leveling. Another similar assembly provides lateral control relating to track alignment corrections.

Entre des longerons 37 du châssis principal 1 est guidé en outre, par des plates-bandes 41 solidaires desdits longerons, une masse 38 formant contrepoids à l'égard du châssis mobile 25 et de ses organes de travail 13, 14. Ce contrepoids peut se déplacer en translation, supporté par quatre galets verticaux 39, et guidé par quatre galets horizontaux 40, suivant un chemin rectiligne parallèle au chemin de déplacement du châssis mobile 25. Il est à cet effet doté d'un entraîneur 42 en prise avec le brin supérieur 31b de la chaîne 31. Le contrepoids 38, y compris ses annexes, présente une masse égale à l'ensemble de travail 25, 13, 14 et à ses annexes. Les distances parcourues par ces éléments mobiles sont constamment égales, avec des vitesses égales mais de sens opposés grâce à la synchronisation de leurs mouvements opérée par la chaîne 31.Between the side members 37 of the main frame 1 is further guided, by flowerbeds 41 integral with said side members, a mass 38 forming a counterweight with respect to the movable frame 25 and its working members 13, 14. This counterweight can be move in translation, supported by four vertical rollers 39, and guided by four horizontal rollers 40, following a rectilinear path parallel to the path of movement of the movable frame 25. It is for this purpose provided with a driver 42 engaged with the upper strand 31b of the chain 31. The counterweight 38, including its annexes, has a mass equal to the working assembly 25, 13, 14 and its annexes. The distances traveled by these mobile elements are constantly equal, with equal speeds but in opposite directions thanks to the synchronization of their movements operated by the chain 31.

En fonctionnement, tous les mouvements de translation longitudinale communiqués à l'ensemble de travail par le groupe moto-réducteur 36, via la chaîne 31 par son brin inférieur 31a, déterminent des mouvements de translation longitudinale égaux et en opposition de phase pour le contrepoids 38, de sorte que les efforts d'inertie engendrés par le déplacement pas à pas des groupes de travail sont annulés par compensation. Ainsi, les mouvements des groupes de travail, même les plus brutaux, qui correspondent à leur passage rapide d'une traverse 4 à la traverse suivante entre deux opérations de bourrage, n'induisent aucune secousse néfaste dans le châssis principal 1 et l'ensemble de l'engin.In operation, all the longitudinal translation movements communicated to the working assembly by the geared motor group 36, via the chain 31 by its lower strand 31a, determine equal longitudinal translation movements and in phase opposition for the counterweight 38 , so that the inertia forces generated by the step-by-step movement of the working groups are canceled by compensation. Thus, the movements of the working groups, even the most brutal, which correspond to their rapid passage from one cross 4 to the next cross between two tamping operations, do not induce any harmful shock in the main chassis 1 and the whole of the machine.

En variante, on peut prévoir deux systèmes d'entraînement en translation indépendants , l'un pour le châssis mobile 25 et l'autre pour le contrepoids 38, chacun d'eux comprenant par exemple une chaîne sans fin actionnée par un moteur hydraulique ainsi que décrit ci-dessus, ou un vérin hydraulique horizontal relié au châssis principal. La synchronisation des mouvements contraires n'est alors plus réalisée mécaniquement, mais électro- hydrauliquement: on peut prévoir à cet effet deux capteurs potentiométriques mesurant la distance parcourue respectivement par le châssis mobile et par le contrepoids, qui, selon une loi de commande en vitesse commune, font varier le débit des deux moteurs ou vérins hydrauliques de translation au moyen d'une soupape électro-hydraulique à action proportionnelle.As a variant, two independent translational drive systems can be provided, one for the movable frame 25 and the other for the counterweight 38, each of them comprising for example an endless chain actuated by a hydraulic motor as well as described above, or a horizontal hydraulic cylinder connected to the main chassis. The synchronization of the opposite movements is then no longer carried out mechanically, but electro-hydraulically: two potentiometric sensors can be provided for this purpose measuring the distance traveled respectively by the movable chassis and by the counterweight, which, according to a speed control law common, vary the flow of the two hydraulic translation motors or cylinders by means of an electro-hydraulic valve with proportional action.

Dans un autre mode de réalisation de l'invention, la quantité de mouvement de compensation, égale et opposée à celle du châssis mobile, est réalisée à l'aide d'un contrepoids de masse plus faible que celle du châssis mobile, mais animé d'une vitesse supérieure à celle de ce dernier, le rapport entre les masses étant égal au rapport inverse des vitesses respectives. Cette forme de réalisation présente l'avantage de diminuer les poids mis en jeu. Elle nécessite cependant des courses différentes pour le châssis mobile et pour le contrepoids. Les systèmes de synchronisation doivent assurer ici un rapport des vitesses différent de l'unité correspondant par exemple à un rapport de pignons, des cylindrées de moteurs d'entrainement ou des sections de vérins hydrauliques différents.In another embodiment of the invention, the amount of compensating movement, equal to and opposite to that of the movable chassis, is carried out using a counterweight of smaller mass than that of the movable chassis, but animated by 'a speed greater than that of the latter, the ratio between the masses being equal to the inverse ratio of the respective speeds. This embodiment has the advantage of reducing the weights involved. However, it requires different strokes for the mobile chassis and for the counterweight. The synchronization systems must ensure here a different speed ratio from the unit corresponding for example to a ratio of pinions, displacements of drive motors or different sections of hydraulic cylinders.
