Abstract

Portable machine tool intended to reestablish the profile of a rail whose active running surface has been adversely altered by protuberances in metal resulting from repair by welding two segments together or by electrical refilling. This machine carries out this work by copying, using feelers enclosing the defect to be repaired, the profile of the rail, and by transferring the contour of this profile to a tool holder girder which reproduces it.

Description

DESCRIPTION
Meuleuse Reprofileuse de Rail
La présente invention concerne une meuleuse reprofileuse portative par copie du rail après réparation de sa surface ou soudure de deux tronçons de rail entre eux.DESCRIPTION
Rail Reprofiling Grinder
The present invention relates to a portable reprofiling grinder by copying the rail after repairing its surface or welding two sections of rail together.

Etat actuel des techniques de meulage de rail après réparation
Après la réparation de la surface d'un rail nécessitée par un rechargement par soudure à l'arc ou après la soudure de deux tronçons de rail par procédé électrique ou aluminothermique, il subsiste un défaut de surface dû à une excroissance du métal qu'il convient de faire disparaître. Cette excroissance de métal est supprimée en deux opérations distinctes. La première qui constitue le dégrossissage est effectuée le plus souvent à l'aide d'unemeule boisseau ou, plus rarement en
France, en utilisant un dispositif de meulage guide, incapable de copier le profil du rail encadrant, notamment aux congés supérieurs où le rayon de courbure de la table de roulement est faible. Néanmoins, ce système est suffisant pour réaliser cette première phase qui laisse subsister une excroissance comprise entre 6/10 et 10/10 de mm.Après ce premier dégrossissage, refroidissement et passage de plusieurs trains, est entreprise la deuxième opération. Elle consiste à rétablir la partie supérieure du rail en contact avec les roues des engins ferroviaires de façon à ce qu'elle présente une parfaite continuité du profil. Elle est actuellement effectuée à l'aide de meules boisseau, tenues à la main par des opérateurs très spécialisés car les tolérances d'exécution sont très faibles (0, + 2/10) et seront prochainement réduites pour s'adapter aux très grandes vitesses. Certains utilisent également le dispositif rudimentaire guidé par le rail dont il est question précédemment et qui nécessite autant de réglages de la meule qu'il est exécuté de passes, sans pour autant reproduire parfaitement le champignon du rail.Current state of rail grinding techniques after repair
After the repair of the surface of a rail required by a reloading by arc welding or after the welding of two sections of rail by electric or aluminothermic process, there remains a surface defect due to a growth of the metal which it should make it go away. This metal outgrowth is removed in two separate operations. The first which constitutes roughing is most often carried out using a cup wheel or, more rarely in
France, using a guide grinding device, unable to copy the profile of the framing rail, in particular at the higher leaves where the radius of curvature of the tread is small. However, this system is sufficient to carry out this first phase which leaves a protrusion of between 6/10 and 10/10 mm. After this first roughing, cooling and passage of several trains, the second operation is undertaken. It consists in restoring the upper part of the rail in contact with the wheels of railway vehicles so that it has perfect continuity of the profile. It is currently carried out using cup wheels, held by hand by very specialized operators because the execution tolerances are very low (0, + 2/10) and will soon be reduced to adapt to very high speeds . Some also use the rudimentary device guided by the rail which is mentioned above and which requires as many adjustments to the wheel as it is executed with passes, without perfectly reproducing the head of the rail.

Innovation du système proposé
L'invention qui fait l'objet de la présente description est une petite machine-outil, d'un poids approximatif de 60 kgs,
ou fraisage qui reprofile parfaitement le rail par meulage, en copiant les profils des parties adjacentes de part et d'autre à éliminer. A noter qu'il est ainsi possible de reconstituer aussi bien le profil d'un rail usé qui n'a plus la forme géométrique initiale du rail neuf, que celui de ce dernier. Le dispositif d'usinage r (meule boisseau (1), fraise ou bande abrasive) mue par un moteur (2) qui peut être hydraulique, électrique ou autre), - est solidaire de deux palpeurs (3) et oscille autour du rail.Ce dispositif permet à l'outil (1), après un réglage initial, à l'aide d'un bouton gradué, de se déplacer aussi bien dans le sens perpendiculaire au rail pour en suivre et reproduire les contours palpés de part et d autre du défaut à éliminer que dans le sers longitudinal. L'opérateur, après avoir effectué le réglage initial, anime l'ensemble porte meule d'un mouvement alternatif horizontal (6) tout en faisant parcourir à l'ensemble une rotation autour du champignon du rail (partie supérieure et faces laLéwales) en manipulant un organe de commande (5). Les manoeuvres effectuées par l'opér-a- teur peuvent faire l'objet d'une mécanisation à l'exception de celle du réglage initial de la meule par rapport au rail.Cette machine permet donc à un opérateur non spécialisé d'effectuer, avec, avec un nombre très réduit de réglages simples, un travail de reprofilage dont les résultats sont aussi bons, sinon meilleurs que ceux obtenus jusqu'ici par des ouvriers très spécialisés. De plus, la meule n'étant plus tenue à la main mais guidée par la machine, il est possible de doubler ( 3 000 à 6 000 T/mn) la vitesse de rotation de la meule et de diminuer le temps d'exécution du travail. Sur le plan de l'ergonomie du du poste de travail, on peut noter les améliorations suivantes par rapport à la méthode manuelle utilisée jusqu'ici - L'opérateur qui peut se tenir plus éloigné de la zone de
meulage est moins soumis aux poussières de métal et d'abra
sifs.Innovation of the proposed system
The invention which is the subject of the present description is a small machine tool, with an approximate weight of 60 kgs,
or milling which perfectly reshapes the rail by grinding, copying the profiles of the adjacent parts on either side to be eliminated. Note that it is thus possible to reconstruct both the profile of a worn rail which no longer has the initial geometric shape of the new rail, as well as that of the latter. The machining device r (cup wheel (1), milling cutter or abrasive belt) driven by a motor (2) which can be hydraulic, electric or other), - is integral with two feelers (3) and oscillates around the rail. This device allows the tool (1), after an initial adjustment, using a graduated button, to move as well in the direction perpendicular to the rail to follow and reproduce the palpated contours on both sides. of the defect to be eliminated only in the longitudinal direction. The operator, after carrying out the initial adjustment, animates the wheel holder assembly with a horizontal reciprocating movement (6) while causing the assembly to run through a rotation around the rail head (upper part and laLéwales faces) by manipulating a control member (5). The maneuvers carried out by the operator can be mechanized with the exception of that of the initial adjustment of the grinding wheel relative to the rail. This machine therefore allows a non-specialized operator to perform, with, with a very small number of simple adjustments, a reprofiling work whose results are as good, if not better than those obtained so far by very specialized workers. In addition, since the grinding wheel is no longer held by hand but guided by the machine, it is possible to double (3,000 to 6,000 rpm) the speed of rotation of the grinding wheel and reduce the execution time of the job. In terms of ergonomics of the workstation, we can note the following improvements compared to the manual method used so far - The operator who can stand further from the
grinding is less subject to metal dust and abr
sifs.

- Le niveau sonore auquel est soumis l'opérateur est moindre
car la source d'énergie est plus éloignée du poste de tra
vail sauf dans le cas d'utilisation du moteur thermique.- The noise level to which the operator is subject is lower
because the energy source is further from the workstation
vail except when using the heat engine.

- En outre, la fatigue de l'opération est diminuée par le fait que la meule n'est plus tenue à bout de bras mais par des barres de glissage (7) qui assurent le support de l'outil par son transfert (6) d'une extrémité à l'autre de la machine.- In addition, the fatigue of the operation is reduced by the fact that the grinding wheel is no longer held at arm's length but by sliding bars (7) which support the tool by its transfer (6) from one end to the other of the machine.

La machine est constituée d'une poutre (8) solidaire de deux palpeurs (3) qui transfèrent à la poutre leur position sur le rail.The machine consists of a beam (8) integral with two feelers (3) which transfer their position on the rail to the beam.

Ces palpeurs (3) ont la surface en contact avec le rail de forme identique à celle de l'outil de meulage. Cette précaution est indispensable pour ne pas induire de distorsion entre le profil copié et celui rétabli. Sur la poutre est fixé, par l'intermédiaire de barres de glissage (7) un ensemble porte outil et moteur qui se déplace longitudinalement (6) sur la poutre (8) par action manuelle. Cette action manuelle peut être remplacée par une motorisation. These feelers (3) have the surface in contact with the rail with a shape identical to that of the grinding tool. This precaution is essential so as not to induce distortion between the copied profile and the restored one. On the beam is fixed, by means of sliding bars (7) a tool holder and motor assembly which moves longitudinally (6) on the beam (8) by manual action. This manual action can be replaced by a motorization.

L'ensemble porte outil (1) est réglé en hauteur à l'aide d'un bouton gradué (4).The tool holder assembly (1) is adjusted in height using a graduated knob (4).

La poutre oscille autour du rail par un système manivelle et pignons dentés (5) qui gravite sur deux secteurs dentés (10) solidaires# du rail par des attaches (11). La manivelle peut être remplacée par une motorisation The beam oscillates around the rail by a crank system and toothed pinions (5) which revolves on two toothed sectors (10) secured # to the rail by fasteners (11). The crank can be replaced by a motorization
