Title (EN) SLEEPER SCREW DRIVING MACHINE WITH HYDRAULIC TRANSMISSION AND ASSOCIATED CONTROL METHOD
(FR) TIREFONNEUSE À TRANSMISSION HYDRAULIQUE ET PROCÉDÉ DE COMMANDE ASSOCIÉ
Abstract:
(EN) The invention relates to a sleeper screw driving machine (1) with hydraulic transmission comprising at least one first sleeper screw driving head (2) and one second sleeper screw driving head (3), said first (2) and second (3) sleeper screw driving heads being intended to screw in or unscrew railway sleeper screws (102), at least a first (4) and a second (5) hydraulic motor suited to the rotational drive of the first sleeper screw driving head (2) and of the second sleeper screw driving head (3) respectively, a control unit (12) configured to control the first (4) and second (5) hydraulic motors, and at least one hydraulic pump (8, 9) intended to supply hydraulic power to the first (4) and second (5) hydraulic motors, characterized in that the sleeper screw driving machine (1) additionally comprises at least one hydraulic distribution member (10) driven by the control unit (12) so that, in a first configuration, it hydraulically connects the first (4) and second (5) hydraulic motors in series in a hydraulic circuit and, in a second configuration, it hydraulically uncouples the first (4) and second (5) hydraulic motors in the hydraulic circuit.
(FR) L'invention concerne une tirefonneuse (1) à transmission hydraulique comprenant au moins une première tête de tirefonnage (2) et une deuxième tête de tirefonnage (3), lesdites première (2) et deuxième (3) têtes de tirefonnage étant destinées à visser ou dévisser des tirefonds (102) de voie ferrée, au moins un premier (4) et un deuxième (5) moteurs hydrauliques adaptés pour entraîner en rotation respectivement la première tête de tirefonnage (2) et la deuxième tête de tirefonnage (3), une unité de commande (12) configurée pour commander le premier (4) et le deuxième (5) moteurs hydrauliques, au moins une pompe hydraulique (8, 9) destinée à alimenter hydrauliquement le premier (4) et le deuxième (5) moteurs hydrauliques, caractérisée en ce que la tirefonneuse (1) comprend en outre au moins un organe de distribution (10) hydraulique piloté par l'unité de commande (12) pour dans une première configuration relier hydrauliquement en série les premier (4) et deuxième (5) moteurs hydrauliques dans un circuit hydraulique, et dans une deuxième configuration, découpler hydrauliquement les premier (4) et deuxième (5) moteurs hydrauliques dans le circuit hydraulique.
