Abstract

DISPOSICION DE MECANISMOS DE PROGRESION PARA UNA ENTIBACION PROGRESIVA, ESPECIALMENTE UNA ENTIBACION DE CABALLETE O DE ESCUDO. CADA UNO DE LOS MECANISMOS DE PROGRESION (S) PRESENTA BARRAS DE GUIA (3) UNIDAS EN UNA CABEZA DE BARRAS (4) QUE EN SUS EXTREMOS DEL LADO DEL RELLENO SE GUIAN CON PIEZAS DE DESLIZAMIENTO (6) EN GUIAS LONGITUDINALES (7) DE LAS TRAVESIAS DEL YACENTE (1, 2) DE LAS UNIDADES DE ENTIBACION. EN LAS PIEZAS DE DESLIZAMIENTO (6) SE HAN ARTICULADO CILINDROS DE PROGRESION (8, 9) CUYOS VASTAGOS DE EMBOLO (10) ESTAN UNIDOS ARTICULADAMENTE CON LAS TRAVESIAS DEL YACENTE. SEGUN LA INVENCION SE HA PREVISTO UN CILINDRO ALINEADOR (16) INTEGRADO EN EL MECANISMO DE PROGRESION, QUE ESTA ACOPLADO CON LAS PARTES DEL MECANISMO DE PROGRESION QUE SE MUEVEN HACIA ADELANTE AL AVANZAR EL CONTRASOPORTE DE PROGRESION (TRANSPORTADOR DE LA GALERIA) EN SENTIDO DE AVANCE, PREFERENTEMENTE LAS ZAPATAS DE DESLIZAMIENTO (6) O LAS PARTES DE CILINDRO DE LOS CILINDROS DE PROGRESION (8, 9).
