Abstract

This device for controlling a railroad track making or repairing machine comprises on the one hand a single laser emitter mounted on a skip standing on the track or the lay-out ahead of the machine, notably a tamping, levelling and lining machine, emits a first fan-shaped or sweeping beam in a horizontal plane and a second fan-shaped or sweeping beam in a vertical plane, and on the other hand two laser receivers mounted on the machine and adapted to adjust themselves automatically as a function of the impact line of one or the other of said laser beams at positions corresponding to the desired positions of the working members of the machine, the laser emitter being mounted on a support permitting its rotation about its track-parallel axis between two end positions spaced 90 degrees apart, these angular positions corresponding the one to the beam in the horizontal plane for levelling operations and the other to the beam in the vertical plane for shifting operations. In a modified version the laser emitter is fixedly mounted and it is only the optical system generating the fan-shaped or sweeping beam that is rotated through 90 degrees by means of a motor.

Description

L'invention concerne un dispositif pour la commande d'une machine pour la construction ou réfection d'une voie de chemin de fer, comprenant d'une part un système d'émetteur laser installé sur un chariot stationné sur la voie ou le tracé devant la machine, et conçu pour émettre un premier faisceau en éventail ou à balayage dans un plan horizontal et un deuxième faisceau en éventail ou à balayage dans un plan vertical, d'autre part un système de récepteur laser installé sur la machine constitué par un premier récepteur pour le faisceau horizontal et un deuxième récepteur pour le faisceau vertical, ces récepteurs étant conçus pour qu'ils s'ajustent automatiquement, en fonction de la ligne d'impact de l'un ou l'autre desdits faisceaux laser, aux positions qui correspondent aux positions voulues des éléments de travail de ladite machine.The invention relates to a device for controlling a machine for the construction or repair of a railway track, comprising on the one hand a laser emitter system installed on a carriage parked on the track or the track in front the machine, and designed to emit a first fan or scanning beam in a horizontal plane and a second fan or scanning beam in a vertical plane, on the other hand a laser receiver system installed on the machine consisting of a first receiver for the horizontal beam and a second receiver for the vertical beam, these receivers being designed so that they automatically adjust, as a function of the line of impact of one or the other of said laser beams, to the positions which correspond to the desired positions of the working elements of said machine.

On connaît déjà l'utilisation de systèmes de mesure à base relative pour les travaux de nivellement et de ripage de la voie, ces systèmes pouvant être notamment montés sur une bourreuse-niveleuse-ripeuse.We already know the use of relative base measurement systems for leveling and track shifting, these systems can in particular be mounted on a tamping-grader-grader.

Ces systèmes de mesure à base relative réduisent les défauts de la voie dans le plan horizontal et vertical en fonction de leur géométrie dans l'échelle 1 : 3 à 1 : 4. Ces systèmes permettent de réduire les défauts géométriques de la voie d'une longueur d'onde inférieure à 20 m. Par contre, pour améliorer les voies avec des ondes plus longues, on est obligé d'utiliser une base de mesure plus longue formée soit par un système optique, soit par un système à laser.These relative-based measurement systems reduce track defects in the horizontal and vertical plane based on their geometry in the 1: 3 to 1: 4 scale. These systems reduce geometric track defects by one wavelength less than 20 m. On the other hand, to improve the channels with longer waves, it is necessary to use a longer measurement base formed either by an optical system, or by a laser system.

Les systèmes à laser actuels utilisent des émetteurs avec des faisceaux en éventail ou à balayage horizontal pour le nivellement ou vertical pour le ripage. Les émetteurs laser, munis des optiques spéciales, émettent des faisceaux horizontaux et verticaux, soit sur le même axe, soit déplacés parallèlement à l'aide de miroirs. Ce système a cependant le désavantage qu'un- partie de la puissance du laser est perdue dans l'optique, il en résulte donc une perte de précision et une réduction de la longueur de travail. Les faisceaux superposés ne peuvent être utilisés qu'en alignement du fait que dans les courbes les deux récepteurs ne suivent pas le même tracé. En utilisant deux émetteurs laser séparés, il est inévitable que le faisceau vertical pour le ripage couvre une fois le champ de travail du faisceau horizontal pour le nivellement, c'est-à-dire que le système devient inopérationnel.Current laser systems use transmitters with fan beams or horizontal scanning beams for leveling or vertical beams for shifting. Laser emitters, fitted with special optics, emit horizontal and vertical beams, either on the same axis, or moved in parallel using mirrors. However, this system has the disadvantage that some of the laser power is lost in optics, which therefore results in a loss of precision and a reduction in the working length. The superimposed beams can only be used in alignment because in the curves the two receivers do not follow the same path. By using two separate laser transmitters, it is inevitable that the vertical beam for shifting once covers the working field of the horizontal beam for leveling, that is to say that the system becomes inoperative.

La présente invention a pour but de remédier à cet inconvénient.The object of the present invention is to remedy this drawback.

A cet effet le dispositif selon l'invention est caractérisé par le fait que le système d'émetteur laser est constitué par un seul émetteur laser, dont au moins une partie, qui définit l'orientation du faisceau, est montée rotativement de manière à lui permettre de tourner autour de l'axe du laser parallèle à la voie, et qu'il est prévu un moteur adapté pour tourner ladite partie entre deux positions distantes angulairement de 900, une première position correspondant au faisceau dans le plan horizontal et une deuxième position correspondant au faisceau dans le plan vertical.To this end, the device according to the invention is characterized in that the laser emitter system is constituted by a single laser emitter, of which at least one part, which defines the orientation of the beam, is rotatably mounted so as to allow it to rotate around the axis of the laser parallel to the track, and there is a motor adapted to rotate said part between two angularly distant positions from 90 0 , a first position corresponding to the beam in the horizontal plane and a second position corresponding to the beam in the vertical plane.

Ainsi, les opérations de ripage et de nivellement peuvent être effectuées au moyen d'un seul émetteur laser dont le faisceau en éventail ou à balayage peut travailler alternativement dans le plan horizontal et dans le plan vertical pour les opérations de nivellement, respectivement de ripage.Thus, the shifting and leveling operations can be carried out by means of a single laser emitter whose fan or scanning beam can work alternately in the horizontal plane and in the vertical plane for the leveling or shifting operations respectively.

Selon une première forme d'exécution de l'invention l'émetteur laser entier est monté sur un support lui permettant de tourner autour de son propre axe parallèle à la voie.According to a first embodiment of the invention, the entire laser transmitter is mounted on a support allowing it to rotate around its own axis parallel to the track.

Selon une deuxième forme d'exécution de l'invention l'émetteur laser est monté fixement et c'est seulement le système optique d'éventail ou de balayage qui est tourné de 90° à l'aide d'un moteur.According to a second embodiment of the invention, the laser transmitter is fixedly mounted and it is only the optical fan or scanning system which is rotated by 90 ° using a motor.

Les machines pour la réfection de voies, surtout les bourreuses-niveleuses-ripeuses, sont très souvent équipées de bases de mesures relatives pour le nivellement et le ripage. Dans ce cas les récepteurs laser selon l'invention sont de préférence liés à la base de mesure relative pour le ripage, respectivement le nivellement, notamment à l'extrémité antérieure de la base correspondante, le récepteur et la base correspondante se déplaçant ensemble pendant l'ajustage automatique du récepteur.Machines for the repair of tracks, especially the tamping-grader-ripers, are very often equipped with relative measurement bases for leveling and shifting. In this case the laser receivers according to the invention are preferably linked to the relative measurement base for the shifting, respectively the leveling, in particular at the anterior end of the corresponding base, the receiver and the corresponding base moving together during the 'automatic receiver adjustment.

En outre, le dispositif selon l'invention est de préférence muni d'un calculateur de flèche des tronçons de voie courbés, horizontaux et le cas échéant verticaux, en fonction du chemin parcouru ; ce calculateur corrige les positions voulues des éléments de travail de la machine, respectivement les positions dedites bases de mesures relatives par rapport au récepteur laser correspondant. Naturellement on peut aussi renoncer à un tel calculateur et effectuer manuellement les corrections de la flèche.In addition, the device according to the invention is preferably provided with a deflection calculator for curved track sections, horizontal and if necessary vertical, as a function of the path traveled; this computer corrects the desired positions of the working elements of the machine, respectively the positions of relative measurement bases with respect to the corresponding laser receiver. Of course, it is also possible to abandon such a calculator and manually make the corrections to the deflection.

La commande de cet émetteur peut être prévue, par exemple dans le cas d'une bourreuse-niveleuse-ripeuse, pour qu'à chaque traverse on travaille en premier lieu avec le faisceau horizontal pour le nivellement, puis on tourne l'émetteur de 90° autour de son axe parallèle à la voie pour le ripage, ou inversement. Une autre possibilité consiste à prévoir une commande pour que le nivellement soit effectué toutes les deux traverses tandis que le ripage est effectué sur les traverses intermédiaires. Cette manière de travail permet un rendement supplémentaire sans perte de précision grâce aux bases relatives qui réduisent les défauts restants entre deux traverses.The control of this transmitter can be provided, for example in the case of a tamper-grader-ripeuse, so that at each crossbar we work first with the horizontal beam for leveling, then we turn the transmitter 90 ° around its axis parallel to the track for shifting, or vice versa. Another possibility is to provide an order so that the leveling is carried out every two sleepers while the shifting is carried out on the intermediate sleepers. This way of working allows an additional output without loss of precision thanks to the relative bases which reduce the remaining defects between two crosspieces.

Dans ce qui suit, l'invention est exposée plus en détail à l'aide des dessins représentant, schématiquement, plusieurs modes d'exécution du dispositif.In what follows, the invention is explained in more detail using the drawings showing, schematically, several embodiments of the device.

Le principe de l'invention, tel qu'illustré schématiquement sur les figures 1 à 9, consiste à prévoir un seul émetteur laser 1, placé devant une machine pour la réfection ou la construction d'une voie de chemin de fer, avançant selon la flèche (fig.l) et schématisée sur les dessins par un châssis 2. Cet émetteur 1 est adapté pour émettre un faisceau en éventail ou à balayage dirigé soit horizontalement pour le nivellement (faisceau Fn), et après une rotation de 90° soit verticalement pour le ripage (faisceau Fr), un récepteur de nivellement Rn et un récepteur de ripage Rr étant montés tous deux sur la machine.The principle of the invention, as illustrated diagrammatically in FIGS. 1 to 9, consists in providing a single laser transmitter 1, placed in front of a machine for the repair or construction of a railway track, advancing according to the arrow (fig.l) and shown schematically in the drawings by a chassis 2. This emitter 1 is suitable for emitting a fan-shaped beam or a directed scan either horizontally for leveling (beam Fn), and after a rotation of 90 ° or vertically for shifting (beam Fr), a leveling receiver Rn and a shifting receiver Rr being both mounted on the machine.

Sur la figure 1 montrant une vue latérale du dispositif de commande du nivellement on a illustré par la ligne 3 l'ancienne voie qui doit être corrigée, les défauts de cette voie ont été naturellement très exagérés pour la compréhension de la figure , en traits pointillés est illustrée la portion de cette ancienne voie qui vient d'être corrigée, la ligne 4 représente la nouvelle voie corrigée et la ligne en traits mixtes 4' représente la voie désirée qui est définie par l'axe du laser lequel est ajusté, en début de travail, parallèlement à cette voie désirée.In Figure 1 showing a side view of the leveling control device is illustrated by line 3 the old way which must be corrected, the faults of this way were naturally very exaggerated for the understanding of the figure, in dotted lines is illustrated the portion of this old channel which has just been corrected, line 4 represents the new corrected channel and the line in phantom 4 'represents the desired channel which is defined by the axis of the laser which is adjusted, at the start of work, parallel to this desired path.

Le dispositif comprend un émetteur laser 1, émettant un faisceau horizontal Fn et qui est monté sur un chariot 5 stationné d'une manière fixe, à un emplacement choisi sur l'ancienne voie 3, en avant de la machine laquelle est, dans le cas considéré, une bourreuse-niveleuse-ripeuse symbolisée par le châssis 2 et qui sera ci-après simplement désignée par machine. Cette machine est équipée d'une base de mesure relative connue, formée par les points A,B,C sur la voie, lesquels sont définis, par exemple, par des palpeurs. Le point C se trouve sur la voie 4 déjà corrigée. Le point A se trouve sur la voie 3 pas encore corrigée et le point B représente le point de travail qui est donc situé à proximité des éléments de travail servant à positionner la voie et qui sont constitués, de la manière connue, par des pinces de ripage et de nivellement. Dans l'exemple considéré sur la figure 1, on a exagéré la position du point A tandis que le point B vient juste d'être corrigé, comme le point C est également corrigé, la machine avec son châssis 2 est inclinée vers l'avant.The device comprises a laser transmitter 1, emitting a horizontal beam Fn and which is mounted on a carriage 5 stationary in a fixed manner, at a location chosen on the old track 3, in front of the machine which is, in the case considered, a tamper-grader-ripper symbolized by the chassis 2 and which will be hereinafter simply designated by machine. This machine is equipped with a known relative measurement base, formed by points A, B, C on the track, which are defined, for example, by feelers. Point C is found on channel 4 already corrected. Point A is on track 3 not yet corrected and point B represents the working point which is therefore located near the working elements used to position the track and which are constituted, in the known manner, by pliers shifting and leveling. In the example considered in Figure 1, we exaggerated the position of point A while point B has just been corrected, as point C is also corrected, the machine with its chassis 2 is tilted forward .

A la hauteur du point A se trouve un récepteur laser pour le nivellement Rn qui peut être ajusté dans le sens vertical par rapport au châssis 2 au moyen d'un moteur d'ajustage Mn. A ce récepteur Rn est fixé un élément qui porte l'extrémité antérieure AL de la ligne de référence Ln appartenant à la base de mesure relative pour le nivellement. Cette extrémité AL se trouve au-dessus du point A. Dans le cas présent, cette ligne de référence Ln est supposée être réalisée par un fil tendu sur la machine, qui est fixe au point CL situé à la hauteur du point C et qui, au point BL, situé à la hauteur du point B, commande par sa position d'une manière bien connue, via un dispositif de commande, la position des pinces de nivellement.At the height of point A is a laser receiver for leveling Rn which can be adjusted vertically with respect to the chassis 2 by means of an adjustment motor Mn. To this receiver Rn is fixed an element which carries the anterior end AL of the reference line Ln belonging to the relative measurement base for leveling. This end AL is located above point A. In the present case, this reference line Ln is supposed to be produced by a wire stretched over the machine, which is fixed at point CL situated at the height of point C and which, at point BL, situated at the height of point B, controls by its position in a well-known manner, via a control device, the position of the leveling clamps.

Le récepteur laser pour le nivellement Rn, comme le récepteur laser pour le ripage Rr dont il sera question ci-après, est constitué par quatre cellules photoélec- triques C1 à C4, représentées sur la figure 3, et il est conçu de telle manière qu'il peut être déplacé dans la position voulue au moyen du moteur d'ajustage Mn en fonction de la ligne d'impact du faisceau laser horizontal Fn sur les cellules, l'ajustement étant réalisé dès que le faisceau se trouve exactement entre les deux cellules centrales C2 et C3.The laser receiver for leveling Rn, like the laser receiver for shifting Rr which will be discussed below, consists of four photoelectric cells C1 to C4, shown in FIG. 3, and it is designed in such a way that '' it can be moved to the desired position by means of the adjustment motor Mn as a function of the line of impact of the horizontal laser beam Fn on the cells, the adjustment being carried out as soon as the beam is exactly between the two central cells C2 and C3.

Dans le cas représenté sur la figure 1, l'ajustage a déjà été effectué de telle manière que la ligne de référence qui avait, avant correction, la position représentée par la ligne L'n a maintenant la position correcte parallèle à l'axe du laser et nommée Ln. Cela signifie que le point BL a été corrigé verticalement de l'écart x qui correspond exactement à la correction verticale x au point de travail B représentant la hauteur dont a été soulevée la voie par les pinces pour atteindre la position voulue. Dans ces conditions, BC représente le tronçon corrigé tandis que AB représente le tronçon non corrigé.In the case shown in FIG. 1, the adjustment has already been carried out in such a way that the reference line which had, before correction, the position represented by the line L'n now has the correct position parallel to the axis of the laser and named Ln. This means that the point BL has been corrected vertically by the difference x which exactly corresponds to the vertical correction x at the working point B representing the height from which the track was lifted by the clamps to reach the desired position. Under these conditions, BC represents the corrected section while AB represents the uncorrected section.

Bien entendu, cette ligne de référence Ln pourrait être formée par n'importe quel autre moyen mécanique ou non, par exemple un rayon lumineux et les points A et C ne se trouvent pas obligatoirement sur le châssis 2 mais peuvent se trouver sur des petits chariots auxiliaires qui rouleraient à une distance fixe à l'avant, respectivement à l'arrière, du châssis 2.Of course, this reference line Ln could be formed by any other mechanical means or not, for example a light ray and the points A and C are not necessarily located on the chassis 2 but can be found on small carriages auxiliaries which would roll at a fixed distance to the front and rear respectively of the chassis 2.

Dans la pratique, si l'on se trouve sur un tronçon de voie ne présentant pas trop de courbures, on peut positionner au départ le chariot 5 portant l'émetteur laser 1 à une distance d'environ 300 mètres de la machine et une fois que celle-ci s'est avancée en cours de travail trop près de l'émetteur, on redéplace le chariot 5 d'une distance d'environ de 300 mètres de la machine. Il faut, bien entendu, tenir compte du fait que dans les régions montagneuses ou vallonnées, il n'y ait pas d'obstacle entre l'émetteur et le récepteur.In practice, if you are on a section of track that does not have too much curvature, you can initially position the carriage 5 carrying the laser transmitter 1 at a distance of approximately 300 meters from the machine and once that the latter has advanced during work too close to the transmitter, the carriage 5 is moved a distance of approximately 300 meters from the machine. It must, of course, be taken into account that in mountainous or hilly regions, there is no obstacle between the transmitter and the receiver.

Sur la figure 2 on a montré d'une manière analogue à la figure 1 une vue de dessus du dispositif de commande du ripage travaillant avec un faisceau laser vertical Fr. Le récepteur de ripage Rr, installé sur le châssis est ajustable par rapport à celui-ci sur un guide transversal en fonction du faisceau vertical Fr par l'intermédiaire d'un moteur Mr. Une ligne de référence Lr est liée au récepteur Rr et on a indiqué, à titre d'exemple, en traits pointillés la ligne de référence L'r à l'état non corrigé, on voit donc dans ce cas à la hauteur du point B lié aux pinces de ripage, que l'écart de correction qui a été effectué est représenté par la distance y. Dans cette vue, on voit que la position A du point de référence comprend les deux points AG sur le rail gauche et AD sur le rail droit.In Figure 2 there is shown in a manner similar to Figure 1 a top view of the device for controlling the shifting working with a vertical laser beam Fr. The shifting receiver Rr, installed on the chassis is adjustable relative to the latter on a transverse guide as a function of the vertical beam Fr by means of a motor Mr. A line of reference Lr is linked to the receiver Rr and the reference line L'r has been indicated, for example, in dotted lines in the uncorrected state, so in this case we see at the height of point B linked to the clamps of shifting, that the correction deviation which has been made is represented by the distance y. In this view, it can be seen that position A of the reference point comprises the two points AG on the left rail and AD on the right rail.

La figure 4 représente schématiquement une section de la voie au niveau des récepteurs de nivellement Rn et de ripage Rr montrant leur position relative et dans ce cas précis on a supposé que le récepteur de ripage Rr se trouve situé sur l'axe central de la voie tandis que le récepteur de nivellement Rn se trouve sur la file directrice qui est généralement la voie la plus basse dans une courbe.FIG. 4 schematically represents a section of the track at the level of the leveling receivers Rn and shifting Rr showing their relative position and in this specific case it has been assumed that the shifting receiver Rr is located on the central axis of the track while the leveling receiver Rn is on the directing line which is generally the lowest path in a curve.

Afin de ne pas surcharger les figures 1 à 4, nous n'avons pas représenté sur celles-ci le dispositif qui corrige la ligne de référence en fonction des flèches soit horizontales soit verticales par rapport au récepteur. Donc, en réalité, la liaison entre les récepteurs et la ligne de référence n'est pas absolument rigide, cette liaison reste fixe et constante pendant tout l'ajustement en fonction du laser, mais elle peut être corrigée en fonction des flèches mesurées, comme cela sera décrit en relation avec la figure 6.In order not to overload Figures 1 to 4, we have not shown on these the device which corrects the reference line according to the arrows either horizontal or vertical relative to the receiver. So, in reality, the connection between the receivers and the reference line is not absolutely rigid, this connection remains fixed and constant throughout the adjustment as a function of the laser, but it can be corrected according to the arrows measured, such as this will be described in relation to FIG. 6.

Sur la figure 5 on a représenté simultanément, en perspective, les deux systèmes et l'on voit le faisceau horizontal Fn et vertical Fr ainsi que les deux récepteurs de nivellement Rn qui peut se déplacer verticalement et de ripage Rr qui peut se déplacer horizontalement. L'émetteur laser 1 se trouve sur l'axe de la voie.In Figure 5 there is shown simultaneously, in perspective, the two systems and we see the do horizontal Fn and vertical ceau as well as the two leveling receivers Rn which can move vertically and shifting receiver Rr which can move horizontally. The laser transmitter 1 is located on the axis of the track.

La figure 6 montre le système de ripage dans une portion courbée de la voie ayant le rayon r. Au début du travail, le faisceau laser Fr crée une corde entre l'émetteur 1 placé au devant de la machine et le récepteur de ripage Rr monté sur la machine. Dans la position initiale le récepteur Rr et la ligne de référence se trouvent au point Ao au centre de la voie. Pendant le travail, si la machine est déplacée selon la flèche S, elle suit la courbe de la voie tandis que le récepteur de ripage suit le faisceau vertical Fr du laser le long de la corde ayant la longueur G, et il se déplace selon les flèches en dehors de la ligne médiane. Si l'on se trouve, par exemple, au point Al le récepteur Rr est déplacé de la distance définie par la flèche fl. Naturellement, dans ce cas, la base de mesure relative, respectivement la ligne de référence ne doit pas suivre le récepteur puisque cette ligne détermine la position des pinces au point B, c'est pourquoi on calcule la flèche f1 en fonction de la courbe et l'on déplace la ligne de référence par rapport au récepteur de la distance fl vers l'extérieur de la courbe. De la même manière, quand le récepteur Rr est au point A2 la ligne de référence est déplacée selon la flèche f2. La longueur de la flèche est la distance entre la position du récepteur Rr ajusté sur le faisceau et la ligne de référence qui détermine la position des éléments de travail sur la courbe voulue.Figure 6 shows the shifting system in a curved portion of the track having the radius r. At the start of work, the laser beam Fr creates a cord between the transmitter 1 placed at the front of the machine and the shifting receiver Rr mounted on the machine. In the initial position the receiver Rr and the reference line are at point Ao in the center of the channel. During work, if the machine is moved according to arrow S, it follows the curve of the track while the shifting receiver follows the vertical beam Fr of the laser along the rope having the length G, and it moves according to the arrows outside the center line. If we are, for example, at point A1 the receiver Rr is moved by the distance defined by the arrow fl. Naturally, in this case, the relative measurement base, respectively the reference line must not follow the receiver since this line determines the position of the clamps at point B, this is why the arrow f1 is calculated as a function of the curve and the reference line is moved relative to the receiver by the distance f1 towards the outside of the curve. Similarly, when the receiver Rr is at point A2 the reference line is moved according to the arrow f2. The length of the arrow is the distance between the position of the receiver Rr adjusted on the beam and the reference line which determines the position of the working elements on the desired curve.

Sur la figure 7 est illustrée une vue en coupe de la voie au niveau du point A2. Le récepteur Rr s'est déplacé de la distance f2 en dehors de la ligne centrale, mais par contre l'extrémité antérieure de la ligne de référence Lr (qui sur la figure est perpendiculaire au plan du dessin) doit être déplacée de cette distance f2 vers la position voulue, c'est-à-dire au centre de la voie. C'est pourquoi, l'extrémité antérieure de la ligne de référence Lr est également déplaçable transversalement par rapport au récepteur Rr. Pendant que selon la figure 2 représentant une section droite de la voie, l'extrémité de la ligne de référence Lr est fixée au milieu du récepteur Rr, dans l'exemple de la figure 7 l'extrémité de cette ligne Lr s'est déplacée de la distance de la flèche f2 et ceci au moyen du moteur Mf monté sur le châssis 2. Pour calculer les flèches fl,f2 etc, au fur et à mesure de l'avance de la machine, on utilise un calculateur de tlèche UC et une unité de mesure du chemin parcouru UM. Le calculateur UC calcule la flèche f d'une manière connue en fonction du rayon r de la courbe et de la longueur G de la corde, et actionne le moteur de positionnement Mf qui déplace le support de la ligne de référence Lr selon la valeur calculée pour réaliser la correction de la flèche Cf, tandis que la position du récepteur Rr est commandée par le faisceau vertical Fr par l'intermédiaire du moteur Mr pour réaliser la correction du ripage Cr.In Figure 7 is illustrated a sectional view of the track at the point A2. The Rr receiver has moved by the distance f2 outside the central line, but on the other hand the anterior end of the reference line Lr (which in the figure is perpendicular to the plane of the drawing) must be moved by this distance f2 towards the desired position, c that is to say in the center of the track. This is why, the anterior end of the reference line Lr is also movable transversely relative to the receiver R r. While according to FIG. 2 representing a cross section of the channel, the end of the reference line Lr is fixed in the middle of the receiver Rr, in the example of FIG. 7 the end of this line Lr has moved of the distance of the arrow f2 and this by means of the motor Mf mounted on the chassis 2. To calculate the arrows fl, f2 etc, as the machine advances, a job calculator UC is used and a unit of measurement for the distance traveled UM. The calculator UC calculates the deflection f in a known manner as a function of the radius r of the curve and the length G of the rope, and actuates the positioning motor Mf which moves the support of the reference line Lr according to the calculated value to perform the correction of the deflection Cf, while the position of the receiver Rr is controlled by the vertical beam Fr via the motor Mr to carry out the correction of the shifting Cr.

Un exemple d'émetteur qui peut être utilisé avec le dispositif susmentionné est illustré sur les figures 8 et 9. L'émetteur laser 1 est constitué de la manière conventionnelle et comporte à l'avant un système optique 10 pour la création du faisceau en éventail ou à balayage comprenant au moins une lentille, respectivement un miroir oscillant de déflexion. L'émetteur laser 1 avec son système d'éventail ou de balayage est monté dans des roulements à bille 11 de manière à pouvoir tourner autour de son axe central Z parallèle à la voie. L'ensemble est monté sur un support 12 qui peut être ajusté verticalement et latéralement par des vis de réglage 13 respectivement 14. L'émetteur est en outre relié par un bras 15 (fig.9) à l'extrémité d'une tige 16 qui peut être déplacée par un moteur 17, de préférence d'un moteur électrique, et qui permet de tourner ledit émetteur 1 de 90° autour de son axe Z selon le faisceau qui doit être émis, horizontal ou vertical.An example of a transmitter which can be used with the aforementioned device is illustrated in FIGS. 8 and 9. The laser transmitter 1 is constituted in the conventional manner and comprises at the front an optical system 10 for the creation of the fan beam. or scanning comprising at least one lens, respectively an oscillating deflection mirror. The laser emitter 1 with its fan or scanning system is mounted in ball bearings 11 so that it can rotate around its central axis Z parallel to the way. The assembly is mounted on a support 12 which can be adjusted vertically and laterally by adjustment screws 13 respectively 14. The transmitter is further connected by an arm 15 (fig. 9) to the end of a rod 16 which can be moved by a motor 17, preferably an electric motor, and which makes it possible to rotate said transmitter 1 by 90 ° around its axis Z according to the beam which must be emitted, horizontal or vertical.

Selon une forme préférée de l'invention, le moteur 17 est équipé d'un récepteur radio 18 qui lui permet d'être commandé par radio, à distance, depuis la machine.According to a preferred form of the invention, the motor 17 is equipped with a radio receiver 18 which allows it to be controlled by radio, remotely, from the machine.

Dans une autre forme d'exécution de l'invention l'émetteur laser proprement dit est monté fixement et c'est seulement le système optique d'éventail ou de balayage qui est monté rotativement de manière à lui permettre de tourner autour de l'axe du laser à l'aide d'un moteur.In another embodiment of the invention the actual laser transmitter is fixedly mounted and it is only the optical fan or scanning system which is rotatably mounted so as to allow it to rotate around the axis of the laser using a motor.

Sur la figure 10 est illustrée en perspective une variante d'utilisation du dispositif. Dans ce cas, l'émetteur 1 émettant le faisceau vertical Fr est placé sur la file directrice et le récepteur de ripage Rr est lui-même placé sur la file directrice. Dans ce cas, on a également schématisé la correction du ripage Cr et la correction de la flèche Cf.In Figure 10 is illustrated in perspective an alternative use of the device. In this case, the transmitter 1 emitting the vertical beam Fr is placed on the director queue and the shift receiver Rr is itself placed on the director queue. In this case, the correction of the shifting Cr and the correction of the deflection Cf have also been shown diagrammatically.

Sur la figure 11 est également illustrée une variante d'utilisation du dispositif, avec l'émetteur 1 émettant le faisceau horizontal Fn et le récepteur de nivellement Rn placés tous deux sur la file directrice. On a schématisé la correction du nivellement Cn qui peut être le cas échéant complété par une correction de la flèche verticale, s'il s'agit d'un tronçon de voie courbé vertical.FIG. 11 also illustrates a variant use of the device, with the emitter 1 emitting the horizontal beam Fn and the leveling receiver Rn both placed on the directing line. The correction for leveling Cn has been schematized, which can be supplemented if necessary by a correction of the vertical deflection, if it is a section of track. curved vertical.

Le dispositif de commande qui vient d'être décrit peut être utilisé de l'une ou l'autre manière suivante :

  • La voie est nivelée et ripée à chaque traverse, c'est-à-dire qu'à chaque traverse on procède premièrement, par exemple, au nivellement en travaillant avec le faisceau horizontal du laser, puis on procède au ripage après avoir tourné l'émetteur laser de 90 pour travailler avec le faisceau vertical.
The control device which has just been described can be used in one of the following ways:
  • The track is leveled and ripped at each cross, that is to say that at each cross we proceed firstly, for example, leveling by working with the horizontal beam of the laser, then we proceed to the shift after having turned the 90 laser transmitter to work with the vertical beam.

La voie est nivelée seulement toutes les deux traverses tandis que le ripage est effectué à chaque traverse intermédiaire.The track is leveled only every two sleepers while shifting is carried out at each intermediate sleeper.

Bien entendu, l'invention n'est pas limitée à l'exemple décrit et l'on peut, en principe, travailler sans base de mesure relative. Dans ce cas, ce sont les récepteurs de nivellement, respectivement de ripage qui commandent directement les éléments de travail, à savoir les pinces.Of course, the invention is not limited to the example described and it is possible, in principle, to work without a relative measurement base. In this case, it is the leveling or shifting receivers respectively which directly control the working elements, namely the grippers.

En outre, ce dispositif avec un seul émetteur peut être appliqué à toute autre machine de réfection ou de construction de la voie, par exemple à une dégarnisseuse, à un train de renouvellement de la voie ou à un train de pose d'une nouvelle voie.In addition, this device with a single transmitter can be applied to any other repair or construction machine for the track, for example to a stripper, to a track renewal train or to a train for laying a new track. .
