Description

La présente invention concerne une meuleuse portative à bande abrasive pour l'entretien des voies de chemins de fer et de tramways, notament pour l'élimination du défaut dit d'usure ondulatoire à la surface de roulement d'un rail. Ce défaut consiste en une alternance périodique de creux et de bosses, d'un pas d'environ 150 mm, résultant de vibrations au passage des rames, et qui sont source de bruit et de fatigue du matériel roulant.The present invention relates to a portable grinder with an abrasive belt for the maintenance of railways and tramways, in particular for the elimination of the so-called wave wear defect on the running surface of a rail. This defect consists of a periodic alternation of hollows and bumps, with a pitch of approximately 150 mm, resulting from vibrations when the trains pass, and which are a source of noise and fatigue of the rolling stock.

Selon un procédé actuel, les rails présentant de l'usure ondulatoire, sont rectifiés au moyen d'un train de meulage. Un tel train, d'un emploi coûteux, ne peut pas ètre utilisé dans certaines zones, comme par exemple près d'un aiguillage. Par ailleurs, seuls les grands réseaux de chemin de fer disposent de ce type d'équipement. On connait également les machines portatives equipées de meules à axe vertical. Ces machines sont peu productives et mal adaptées au traitement de longueurs de rails de quelques centaines de mètres On connait encore les meuleuses à bande abrasive selon brevet 89.16299, plus spécialement adaptées au meulage de soudures. According to a current process, the rails having wave wear are rectified by means of a grinding train. Such an expensive train cannot be used in certain areas, such as near a switch. Furthermore, only the major railway networks have this type of equipment. We also know portable machines fitted with grinding wheels with vertical axis. These machines are not very productive and ill-suited to the treatment of rail lengths of a few hundred meters. We also know of abrasive belt grinders according to patent 89.16299, more especially suitable for grinding welds.

La machine, objet du présent brevet répond au besoin d'un équipement léger et maniable permettant une intervention rapide avant aggravation de l'usure ondulatoire des rails. The machine which is the subject of this patent responds to the need for light and handy equipment allowing rapid intervention before aggravation of the wave wear of the rails.

La présente invention a pour objet une meuleuse portative equipée d'une bande abrasive à grand rendement, pour la réctification des défauts d'usure ondulatoire d'un rail de chemin de fer ou de tramway, comportant un bati, recevant un moteur d'entrainement, une poulie motrice et une poulie réceptrice d'une bande abrasive, deux galets support de roulement au contact du rail à meuler, un patin d'appui au contact de la face interne de la bande abrasive pour le maintien de la-dite bande sur le rail, et un dispositif de descente et de relevage du patin. The present invention relates to a portable grinder equipped with a high-performance abrasive belt, for the rectification of undulatory wear defects of a railroad or tramway rail, comprising a frame, receiving a drive motor. , a driving pulley and a pulley receiving an abrasive belt, two rollers bearing support in contact with the rail to be ground, a support pad in contact with the internal face of the abrasive belt for the maintenance of said band on the rail, and a device for lowering and lifting the skate.

Selon une autre caractéristique non limitative de l'invention, I'axe support du patin est relié à un levier de manoeuvre par l'intermédiaire d'une barre téléscopique comportant un ressort permettant le maintien de l'effort d'appui de la bande au rail après vérouillage en position dudit levier dont une extrémité est articulée à un montant solidaire du bati et dont l'autre extremité comporte un moyen d'immobilisation sur un autre montant solidaire du bati.  According to another non-limiting characteristic of the invention, the support axis of the shoe is connected to an operating lever by means of a telescopic bar comprising a spring allowing the support force of the strip to be maintained at rail after locking in position of said lever, one end of which is articulated to an upright secured to the frame and the other end of which comprises means for immobilizing another upright secured to the frame.

Selon une autre caractéristique de l'invention,le patin comporte sur la face symétrique aux galets par rapport à l'axe d'articulation,une plaque de glissement pour la mise en appui sur la face interne de la bande abrasive après retournement du patin de 180 degrés
Selon une autre caractéristique de l'invention,le patin,dont la longueur est supérieure au pas des dénivellations à égaliser ,s'aligne librement autour de son axe support,suivant la direction du rail en cours de meulage, et la bande abrasive ne touche que les parties saillantes de la surface du rail.According to another characteristic of the invention, the pad comprises on the face symmetrical with the rollers with respect to the axis of articulation, a sliding plate for pressing on the internal face of the abrasive belt after turning the pad 180 degree
According to another characteristic of the invention, the shoe, the length of which is greater than the pitch of the unevennesses to be equalized, aligns freely around its support axis, in the direction of the rail during grinding, and the abrasive strip does not touch than the protrusions of the rail surface.

La Fig. 1 représente en élevation la machine selon l'invention
Selon la fig. 1 la machine comporte un bati principal 1 recevant les galets support 2 et 2a en appui au rail 3 à rectifier. Ces galets sont disposés de part et d'autre des poulies 4 et 5 respectivement motrices et récéptrices de la bande abrasive 6. Un moteur 7 entraine la poulie 4 par l'intermédiaire de la courroie de transmission 8 et des poulies 9, 9a.Fig. 1 shows in elevation the machine according to the invention
According to fig. 1 the machine comprises a main frame 1 receiving the support rollers 2 and 2a bearing on the rail 3 to be rectified. These rollers are arranged on either side of the pulleys 4 and 5 respectively driving and receptrating the abrasive belt 6. A motor 7 drives the pulley 4 by means of the transmission belt 8 and pulleys 9, 9a.

Un patin 10 équippé d'une rangée de galets 11, 11A de contact à la bande abrasive 6 est disposé entre les poulies 4 et 5 et articulé librement autour d' un axe 12 orienté perpendiculairement au plan médian du rail.A shoe 10 equipped with a row of rollers 11, 11A for contacting the abrasive belt 6 is disposed between the pulleys 4 and 5 and freely articulated around an axis 12 oriented perpendicularly to the median plane of the rail.

Selon un mode non limitatif de réalisation de l'invention, l'axe 12 est relié par une barre téléscopique 13 à la partie médiane d'un levier de manoevre 14. Cette barre téléscopique comporte un élément élastique tel qu'un ressort de compression 15, une articulation 16 et un moyen de guidage 17 solidaire du bati 1.According to a nonlimiting embodiment of the invention, the axis 12 is connected by a telescopic bar 13 to the middle part of a maneuvering lever 14. This telescopic bar comprises an elastic element such as a compression spring 15 , a joint 16 and a guide means 17 secured to the frame 1.

Le levier 14 est articulé à une extrémité à un montant 18 solidaire du bati principal 1 au moyen d'un axe 19, et relié à l'autre extrémité à un montant 18a au moyen d'un dispositif connu de vérouillage 20, permettant le blocage et le maintien en pression du ressort 15 après abaissement du levier 14. The lever 14 is articulated at one end to an upright 18 secured to the main frame 1 by means of a pin 19, and connected at the other end to an upright 18a by means of a known locking device 20, allowing blocking and maintaining the pressure of the spring 15 after lowering the lever 14.

Le patin 10 reçoit une plaque de glissement 21 disposée sur la face opposée aux galets 11, 11A par rapport à l'axe 12 permettant, après rotation de 180 degrés du patin 10, la mise en contact de la bande abrasive 6 au rail 3. The pad 10 receives a sliding plate 21 disposed on the face opposite the rollers 11, 11A relative to the axis 12 allowing, after rotation of the pad 10 by 180 degrees, bringing the abrasive strip 6 into contact with the rail 3.

Le fonctionnement de la machine est le suivant:
La machine étant posée sur le rail 3, en appui sur les galets 2 et 2a, et stabilisée au moyen d'une barre d'équilibrage non représentée sur la fig. 1, le levier 14 étant en position haute de sorte à décoller légèrement le patin 10 de la bande abrasive 6 et de la surface du rail, on met en marche le moteur 7. La bande abrasive 6 étant en mouvement, on peut abaisser le levier 14 en avançant simultanément la machine sur la voie tout en maintenant I' effort de compression sur le ressort 15, au moyen du levier 14 que l'on vérouille alors en position par un système rapide à came 20. Pendant l'opération de meulage l'opérateur pousse la machine le long de la voie, et passe plusieur fois jusqu'à élimination complète des dénivellations de la zone traitée.The operation of the machine is as follows:
The machine being placed on the rail 3, bearing on the rollers 2 and 2a, and stabilized by means of a balancing bar not shown in FIG. 1, the lever 14 being in the high position so as to slightly detach the pad 10 from the abrasive strip 6 and from the surface of the rail, the motor 7 is started. The abrasive strip 6 being in motion, the lever can be lowered 14 by simultaneously advancing the machine on the track while maintaining the compression force on the spring 15, by means of the lever 14 which is then locked in position by a rapid cam system 20. During the grinding operation l he operator pushes the machine along the track, and goes through it several times until the unevenness in the treated area is completely eliminated.

La longueur du patin étant supérieure au pas des dénivellations à égaliser la bande abrasive arase les parties saillantes jusqu'à leur élimination, sans réglages, le patin s'alignant automatiquement sur le rail autour de l'axe support 12 pendant l'opération de 7 meulage.The length of the pad being greater than the pitch of the unevennesses to equalize the abrasive strip level the protruding parts until their elimination, without adjustments, the pad automatically aligning itself on the rail around the support axis 12 during the operation of 7 grinding.

Le patinl0 comporte une plaque de glissement 21 fixée sur la face symétrique aux galets 11,11 a... par rapport à l'axe 12, permettant, après rotation de 180 degrés du patin la mise en appui de ladite plaque sur la bande abrasive 6 pour une passe de lissage en finition de rectification.The pad 0 has a sliding plate 21 fixed on the face symmetrical to the rollers 11, 11 a ... with respect to the axis 12, allowing, after rotation of the pad 180 degrees, the bearing of said plate on the abrasive belt 6 for a smoothing pass in rectification finish.

Afin de maintenir constante la tension de la bande abrasive pendant l'abaissement et le relevage du patin 10, la poulie réceptrice 5 est montée sur un palier coulissant non représenté avec tendeur. In order to keep the tension of the abrasive belt constant during the lowering and raising of the shoe 10, the receiving pulley 5 is mounted on a sliding bearing, not shown, with tensioner.
