Abstract
Description
La présente invention concerne un dispositif de libération des contraintes internes des longs rails soudés, à progression continue, par un chariot motorisé. The present invention relates to a device for releasing internal stresses from long welded rails, with continuous progression, by a motorized carriage.
il est connu que les rails ou voies ferrées sont sujets à des contraintes méeaniques dans leur structure interne consécutives au fait qu'ils subissent de grands écarts de températures saisonnières, ou à la suite de travaux ou encore de remplacements de tronçons accidentés. It is known that rails or railways are subject to meeanic constraints in their internal structure consecutive to the fact that they undergo large seasonal temperature differences, or following work or even replacement of damaged sections.
Pour libérer les rails de ces contraintes on a été amené à desserrer les attaches et mettre le rail sur rouleaux pour réduire au maximum les frottements entre rails et traverses et faire vibrer toutes les parties du rail desserrées ou à chauffer artificiellement. La méthode couramment adoptée consiste à faire marteler de place en place le champignon par des travailleurs au moyen de maillets en bronze. To release the rails from these constraints, it was necessary to loosen the fasteners and put the rail on rollers to reduce as much as possible the friction between rails and sleepers and make all the loose parts of the rail vibrate or to be heated artificially. The commonly adopted method is to hammer the mushroom from place to place by workers using bronze mallets.
Cette dernière méthode nécessite une main-d'oeuvre nombreuse car le rendement est faible et progressivement décroissant dans la journée par suite de l'effort physique important qu'elle requiert. The latter method requires a large workforce because the yield is low and gradually decreasing during the day due to the significant physical effort it requires.
Ensuite, la succession discontinue de frappes localisées d'intensités variables n'est pas de nature à garantir un résultat rigoureux. Then, the discontinuous succession of localized strikes of varying intensities is not likely to guarantee a rigorous result.
La présente invention remédie à ces inconvénients par la réalisation d'un chariot autonome roulant sur les rails, équipé d'un mécanisme imprimant à la file de rail préalablement desserrée et mise sur rouleaux une poussée transversale alternativement dans un sens puis dans l'autre, en prenant sa réaction sur l'autre file de rail restant solidarisée aux traverses. Ce chariot est sommairement constitué par un châssis comportant un moteur servant à la fois pour son entrainement et pour transmettre à une paire de galets emprisonnant les flancs du champignon, les actions transversales au moyen d'une bielle actionnée par un excentrique à la sortie d'un variateur de vitesse classique. The present invention remedies these drawbacks by producing an autonomous carriage rolling on the rails, equipped with a mechanism which prints the rail file previously loosened and puts on transverse thrust alternately in one direction then in the other, by taking its reaction on the other file of rail remaining joined to the sleepers. This carriage is roughly constituted by a chassis comprising a motor serving both for its drive and for transmitting to a pair of rollers trapping the sides of the mushroom, the transverse actions by means of a connecting rod actuated by an eccentric at the outlet of a conventional speed variator.
La combinaison du mouvement vibratoire des galets et de la translation du chariot engendre un déplacement ondulatoire continu du rail. The combination of the vibratory movement of the rollers and the translation of the carriage generates a continuous wave movement of the rail.
Le variateur de vitesse permet de régler la fréquence de la yibration en fonction de la nature des rails traités. Le dispositif est complèté par un réducteur entraînant une roue motrice du chariot par l'intermédiaire d'un second variateur avec lequel la vitesse de translation du chariot peut varier de façon à pouvoir régler le pas de l'onde de vibration. The variable speed drive allows you to adjust the frequency of the yibration according to the nature of the treated rails. The device is supplemented by a reduction gear driving a driving wheel of the carriage by means of a second variator with which the speed of translation of the carriage can vary so as to be able to adjust the pitch of the vibration wave.
La description qui va suivre, en regard du dessin annexé à titre d'exemple non limitatif, permettra de bien comprendre comment la présente invention peut être mise en pratique. The description which follows, with reference to the attached drawing by way of nonlimiting example, will make it possible to understand clearly how the present invention can be put into practice.
La figure 1 représente une coupe transversale suivant I-I du chariot, où l'on voit le rail à traiter 1 avec son champignon la, desserré et monté sur rouleaux lb (l'autre rail de la voie restant serré). Les galets 2 sont maintenus par deux supports 3 articulés autour d'un axe 4 solidaire du châssis 5. Figure 1 shows a cross section along I-I of the carriage, where we see the rail to be treated 1 with its mushroom 1a, loose and mounted on rollers 1b (the other rail of the track remaining tight). The rollers 2 are held by two supports 3 articulated around an axis 4 secured to the chassis 5.
Le serrage de ces galets est assuré par une vis à pas inversés 6 agissant sur des écrous prisonniers 7. These rollers are tightened by an inverted pitch screw 6 acting on captive nuts 7.
L'excentrique 9 communique un mouvement à une bielle 8 dont le pied est relié à une noix 8a maintenue sur la partie médiane de la vis 6 des galets transmettant ainsi la vibration à ces derniers. The eccentric 9 communicates a movement to a connecting rod 8, the foot of which is connected to a nut 8a held on the middle part of the screw 6 of the rollers, thus transmitting the vibration to the latter.
A droite de cette figure on distingue deux roues 10 et 11 portant sur les bords du champignon du rail opposé, dont le serrage s'effectue par une vis à papillon 19. La roue 10 est entraînée parle moteur par l'intermédiaire d'un réducteur 12 et d'un embrayage 13, et d'un variateur 14 assurant ainsi le déplacement du chariot. To the right of this figure there are two wheels 10 and 11 bearing on the edges of the head of the opposite rail, the tightening of which is effected by a butterfly screw 19. The wheel 10 is driven by the motor by means of a reduction gear 12 and a clutch 13, and a variator 14 thus ensuring the movement of the carriage.
La figure 2 est une vue de dessus de la précédente où l'on distingue le bloc moteur 15, l'embrayage 16 et le variateur 17 de l'excentrique 9. FIG. 2 is a top view of the previous one, where there are the engine block 15, the clutch 16 and the variator 17 of the eccentric 9.
On voit également un galet support 18 constituant le troisième point d'appui du chariot. We also see a support roller 18 constituting the third support point of the carriage.
