Title
(EN) PROCESS FOR CONTINUOUS WELDING OF TRACK SECTIONS, AND SET OF WAGONS ESPECIALLY EQUIPPED FOR ITS IMPLEMENTATION
(FR) PROCEDE POUR LE SOUDAGE EN CONTINU DE TRONÇONS DE RAIL, ET RAME EQUIPEE POUR SA MISE EN ×UVRE
Abstract
(EN)
A process for the continuous welding of railway track sections (3) during installation, in which a set of wagons, especially equipped for the purpose (5-5'), and made up of one or more wagons (5, 5') with an extra-low load plane, is introduced into the line of operation, between the wagons (1) carrying the new track sections (3) and the new cross beams (2) and the operating machine installing said beams and sections. The operations aligning, levelling and butting successive track sections (3) take place on said set of wagons (5-5'), as does the welding of said sections, which involves the movement of welding machines (15-17) on a trolley (8) along the set of wagons (5-5'). The welding operations are carried out during a run of the trolley (8) along with the welding machines (15-17) in the opposite direction to that of the advancing line of operation. This welding run is then compensated by a return run of the trolley (8) and welding machines (15-17) in the same direction as the line of operation. In this way, all the welding takes place on the operation line itself, installation being carried out by the corresponding operating machine on tracks which are now continuous.
(FR)
Un procédé pour le soudage en continu de tronçons (3) de rail ferroviaire en cours de pose, dans lequel une rame (5-5') spécialement équipée, composée par un ou plusieurs wagons (5, 5') au plan de charge surbaissé, est insérée dans le train opérateur, entre les wagons (1) qui portent les nouveaux tronçons de rail (3) et les nouvelles traverses (2), et la machine opératrice qui en fait la pose, et sur cette rame équipée (5-5') sont effectuées les opérations d'alignement, de nivellement et d'aboutement des tronçons successifs de rail (3), et leur soudage, moyennant des machines soudeuses (15-17) mouvant sur un chariot (8) le long de la rame (5-5'), les opérations de soudage étant effectuées pendant une course du chariot (8) avec les machines soudeuses (15-17) dans le sens opposé au sens d'avancement du train opérateur, et ladite course de soudage étant ensuite compensée par une course de retour du chariot (8) avec les machines soudeuses (15-17) dans le même sens de l'avancement du train opérateur, de sorte que toute l'opération de soudage est effectuée sur le train opérateur lui-même et la pose est effectuée par la machine opératrice correspondante sur des rails désormais continus.
