Title: (DE) VORSCHUBFAHRZEUG FÜR EIN KONTINUIERLICH ARBEITENDES ABBAUGERÄT
(EN) LAUNCH VEHICLE FOR CONTINUOUS MINING APPARATUS
(FR) VEHICULE DE POSITIONNEMENT POUR APPAREIL D'ABATTAGE EN CONTINU
Abstract: front page image
(EN) A launch vehicle (10) is provided for a continuous mining system including modular conveyor units (U) that may be connected together to form a conveyor train (T). The launch vehicle (10) includes an elongated frame (12) that holds a belt conveyor (14) for conveying aggregate material that is received from the conveyor train (T). A drive assembly (34) for selectively advancing and withdrawing the conveyor train is also provided on the launch vehicle. Additionally, the launch vehicle includes a mechanism (52) for adding a modular conveyor unit to the conveyor train. More specifically, the conveyor train drive assembly (34) includes a pair of cooperating tandem drive cylinders (36, 38). Each drive cylinder includes a pusher arm unit (42) that is adapted to engage one of the modular conveyor units of the conveyor train. The conveyor unit adding mechanism includes a positioning mechanism that holds and places a conveyor unit on the launch vehicle. A pusher cylinder is also provided to push the new conveyor unit into engagement with the rear of the conveyor train. The launch vehicle also includes an extensible front end.
(FR) On décrit un véhicule de positionnement (10) utilisé dans un système d'abattage continu comprenant des unités de transport modulaires (U) qui peuvent être accouplées pour former un train de transport (T). Le véhicule de positionnement (10) comprend un châssis allongé (12) qui soutient un convoyeur à bande (14) servant à transporter un matériau sous forme d'agrégat reçu à partir du train de transport (T). Un ensemble d'entraînement (34) servant à faire avancer ou reculer sélectivement le train est aussi inclus sur le véhicule de positionnement. En outre, ce véhicule comporte un mécanisme (52) servant à ajouter une unité de transport modulaire au train. Plus particulièrement, l'ensemble d'entraînement (34) du train de transport comprend une paire de vérins (36, 38) d'entraînement en tandem coopérants. Chaque vérin comprend une unité à bras de poussée (42) conçue pour s'engager dans l'une des unités modulaires du train de transport. Le mécanisme d'accouplement d'unité de transport comporte un mécanisme de positionnement qui retient et place une unité sur le véhicule de lancement. Un cylindre de poussée sert en outre à pousser la nouvelle unité de transport de façon qu'elle s'accroche à l'arrière du train de transport. Le véhicule de lancement comprend aussi une extrémité avant extensible.
