Title
(EN) ARRANGEMENT IN UNDERGROUND MINING MACHINE, AND METHOD
(FR) AGENCEMENT DANS UNE MACHINE D'EXPLOITATION MINIÈRE SOUTERRAINE ET PROCÉDÉ ASSOCIÉ
Abstract
(EN)
An arrangement and method of underground mobile mining machine (M) for cable reeling. The arrangement comprises a reel (1), and hydraulic components, comprising: a hydraulic motor (5) connected to and for rotating the reel, a tension control valve manifold (4) configured to control tension of the cable, a pump (8) hydraulically coupled to the hydraulic motor (5) by a reeling-in line (26) and a reeling out line (27), the pump arranged to control pressure fluid flow and direction, a control device (10) arranged to control displacement and the pumping direction of the pump (8), a pump proportional valve (11) arranged to control displacement and delivery of the pump (8), and connected to the control device (10), a first throttle (22) arranged between the pump proportional valve (11) and the control device (10), a second throttle (23) connected to the control device (10). The hydraulic components establishes a closed hydraulic system, and the pump (8) is connected to a system (33) configured to generate a braking moment counteracting a moment caused by a cable (25) unwinding from the reel (1).
(FR)
L'invention concerne un agencement et un procédé associés à une machine d'exploitation minière mobile souterraine (M) pour l'enroulement de câbles. L'agencement comprend une bobine (1) et des composants hydrauliques, comprenant : un moteur hydraulique (5) relié à la bobine et destiné à la faire tourner, un collecteur de soupape de commande de tension (4) conçu pour commander la tension du câble, une pompe (8) couplée hydrauliquement au moteur hydraulique (5) par une ligne d'enroulement (26) et une ligne de déroulement (27), la pompe étant conçue pour commander l'écoulement et la direction du fluide de pression, un dispositif de commande (10) agencé pour commander le déplacement et la direction de pompage de la pompe (8), une soupape proportionnelle de pompe (11) agencée pour commander le déplacement et l'administration de la pompe (8) et reliée au dispositif de commande (10), un premier étranglement (22) disposé entre la soupape proportionnelle de pompe (11) et le dispositif de commande (10), un deuxième étranglement (23) relié au dispositif de commande (10). Les composants hydrauliques établissent un système hydraulique fermé, et la pompe (8) est reliée à un système (33) conçu pour générer un moment de freinage à l'encontre d'un moment provoqué par un câble (25) se déroulant de la bobine (1).
