Title (EN) MECHANIZED SUPPORT UNIT
(FR) UNITE DE SUPPORT MECANISE
Abstract: front page image
(EN)A mechanized support unit serving to maintain the gallery in a safe operational condition during underground mining works, comprises a prop (1) hingedly mounted between a cap (2) and a shoe (3), and a device (4) for compensation of the prop list, including a main correcting hydraulic cylinder (5) presetting the position of the prop (1) at the beginning of each technological cycle, an additional correcting hydraulic cylinder (6) ajusting the position of the prop (1) at any nth cycle, and a means (11) for calculation of a mathematical expectation of the list of the prop after n cycles, connected with its input to the prop (1) and with its output, through a valve (12), to the additional correcting hydraulic cylinder (6), its casing (7) being fixed to a base, in relation to which the position of the prop (1) is preset, and its rod (9) being hingedly connected to the casing (8) of the main correcting hydraulic cylinder (5) which is translatively movable in relation to the casing (7) of the additional correcting hydraulic cylinder (6).
(FR)Une unite de support mecanise sert a maintenir la galerie dans des conditions de fonctionnement sures pendant les travaux d"exploitation miniere en sous-sol, et comprend un etai (1) monte de maniere articulee entre un chapeau (2) et un patin (3), et un dispositif (4) de compensation de l"inclinaison de l"etai, comprenant un verin hydraulique principal de correction (5) etablissant a l"avance la position de l"etai (1) au debut de chaque cycle technologique, un verin hydraulique supplementaire de correction (6) reglant la position de l"etai (1) a tout nieme cycle, et un moyen (11) de calcul d"une probabilite mathematique de l"inclinaison de l"etai apres n cycles, connecte a son entree a l"etai (1) et a sa sortie, par l"intermediaire d"une vanne (12), au verin hydraulique supplementaire de correction (6), son enceinte (7) etant fixee a une embase par rapport a laquelle la position de l"etai (1) est preetablie, et sa bielle (9) etant reliee de maniere articulee au corps (8) du verin hydraulique principal de correction (5) qui est mobile en translation par rapport au corps (7) du verin hydraulique supplementaire de correction (6).
