LE TRANSPORTEUR-ELEVATEUR COMPREND UNE STRUCTURE PORTANTE PRINCIPALE 10 MONTEE SUR DES VOIES 11 AFIN DE SE DEPLACER LE LONG D'UN NIVEAU SUPERIEUR 14, UN CONVOYEUR-ELEVATEUR 13 SUPPORTE PAR UNE FLECHE 12 POUVANT ETRE DEPLOYEE ET RETRACTEE PAR RAPPORT A LA STRUCTURE 10; LA FLECHE 12, FORMEE DE PLUSIEURS SEGMENTS 22 PASSE, EN COURS DE DEPLOIEMENT ET DE RETRACTION, SUR UN CHASSIS DE GUIDAGE 29 INCURVE VERS L'EXTERIEUR ET VERS LE BAS; LES SEGMENTS 22 SONT RELIES DE FACON ARTICULEE PAR LEURS BORDS INFERIEURS DE TELLE SORTE QUE LA FLECHE SOIT PLIEE VERS LE BAS LE LONG DE SA CORDE INFERIEURE A L'ENDROIT DES CHARNIERES 23 ENTRE LES SEGMENTS 22 QUAND ELLE PASSE SUR LE CHASSIS DE GUIDAGE ET DESCEND JUSQU'A UN NIVEAU INFERIEUR 15; L'INTERACTION DES SEGMENTS 22 ETANT TELLE QU'UN PLIAGE DANS LA DIRECTION OPPOSEE SOIT CONTRE-BALANCE AFIN DE FORMER UNE STRUCTURE DE FLECHE RIGIDE; IL EST PREVU UN CONVOYEUR-COLLECTEUR 16 SUR LA LONGUEUR DE LA STRUCTURE 10 POUR AMENER LA MATIERE EN UN POINT DE DECHARGEMENT.APPLICATION AUX EXPLOITATIONS MINIERES A CIEL OUVERT. A mobile elevator conveyor, comprising a main support structure (10) mounted on tracks (11), for mobility along an upper level (14) when in use, an elevating conveyor (13) supported on a boom (12) adapted to be extended from a retracted position within the main frame to an extended position outwardly of said main frame. The boom supporting the conveyor is formed from a plurality of boom segments (22), and is adapted, during extension and retraction, to pass over an outwardly and downwardly curving guide frame (29) mounted on said main support structure. The boom segments are hingedly connected at their lower edges such that the boom structure bends downwardly along its bottom chord at the hinges (23) between the boom segments as it moves over the guide frame, and down to a lower level (15). The interaction of the boom segments is such that bending in the opposite direction is resisted so as to form a rigid boom structure. A collecting conveyor (38) extends along the length of the main support structure and receives material from said elevating conveyor and conveys it to a discharge point.
