Abstract
L’invention concerne une machine de levage (100) configurée pour lever un rail (101) d’une voie de chemin de fer, comprenant un châssis (1), une partie mobile (2) montée à translation par rapport au châssis (1) selon une direction principale (D) et apte à venir en contact avec le sol (S) ou une traverse (102), une pince (4) solidaire du châssis (1) variant entre une configuration ouverte dans laquelle la pince (4) présente une ouverture strictement supérieure à la largeur d’un champignon (103) du rail (101) à lever, et une configuration fermée dans laquelle la pince (4) présente une ouverture strictement inférieure à la largeur du champignon (103) du rail (101), un actionneur (5) assurant un déplacement de la partie mobile (2) par rapport au châssis (1) suivant la direction principale (D) sur une course totale comprise entre une première position maximale et une deuxième position maximale, et un mécanisme de transformation de mouvements (6) convertissant le déplacement de la partie mobile (2) en direction de la deuxième position maximale en un passage de la pince (4) de la configuration ouverte à la configuration fermée, et convertissant le déplacement de la partie mobile (2) en direction de la première position maximale en un passage de la pince (4) de la configuration fermée à la configuration ouverte. Figure 1The invention relates to a lifting machine (100) configured to lift a rail (101) of a railway track, comprising a chassis (1), a movable part (2) mounted in translation relative to the chassis (1) in a main direction (D) and capable of coming into contact with the ground (S) or a sleeper (102), a clamp (4) secured to the chassis (1) varying between an open configuration in which the clamp (4) has an opening strictly greater than the width of a rail head (103) of the rail (101) to be lifted, and a closed configuration in which the clamp (4) has an opening strictly less than the width of the rail head (103) of the rail (101), an actuator (5) ensuring a movement of the movable part (2) relative to the chassis (1) in the main direction (D) over a total stroke between a first maximum position and a second maximum position, and a movement transformation mechanism (6) converting the movement of the movable part (2) in the direction of the second maximum position into a passage of the clamp (4) from the open configuration to the closed configuration, and converting the movement of the movable part (2) in the direction of the first maximum position into a passage of the clamp (4) from the closed configuration to the open configuration. Figure 1
