Title
(EN) METHOD FOR FIXING A RAIL OF A RAIL TRACK WITH THERMAL CONDITIONING OF A RAIL PORTION, AND ASSOCIATED RAIL MACHINE
(FR) PROCÉDÉ D'IMMOBILISATION D'UN RAIL DE VOIE FERRÉE AVEC CONDITIONNEMENT THERMIQUE D'UNE PORTION DE RAIL, ET MACHINE FERROVIAIRE ASSOCIÉE
Abstract
(EN)
In order to fix a rail (12) of a rail track using a rail machine (4), the rail machine (4) is moved in a working direction (100) so that at all times a rail portion (12) which is not attached to a cross-member (8, 10) of the rail track (2) passes through a thermal conditioning zone (30) of a thermal conditioning device (32) of the rail machine (4), a temperature of a surface region of the rail portion passing through the thermal conditioning zone (30) is modified using the thermal conditioning device (32) by generating a non-homogeneous temperature distribution in the rail portion, and the rail portion (12) is fixed to a cross-member (10) of the rail track, after modification of the temperature of the surface region of the rail portion, without waiting for the temperature distribution in the rail portion to be homogenised.
(FR)
Pour immobiliser un rail (12) d'une voie ferrée à l'aide d'une machine ferroviaire (4), on déplace la machine ferroviaire (4) dans une direction de travail (100), de manière qu'à chaque instant une portion du rail (12), non fixée à une traverse (8, 10) de la voie ferrée (2), traverse une zone de conditionnement thermique (30) d'un dispositif de conditionnement thermique (32) de la machine ferroviaire (4), on modifie une température d'une région superficielle de la portion du rail traversant la zone de conditionnement thermique (30) à l'aide du dispositif de conditionnement thermique (32), en générant une distribution de température non homogène dans la portion de rail, et l'on immobilise la portion du rail (12) sur une traverse (10) de la voie ferrée, après modification de la température de la région superficielle de la portion du rail, sans attendre que la distribution de la température dans la portion du rail soit homogénéisée.
