Abstract

SISTEMA DE CONTROL PARA ELEVADORES DE PRENSAS HIDRAULICAS. EL CUERPO DEL ELEVADOR (14) ALOJA EN EL INTERIOR DE SU ANIMA (12) EL GATO (10) DE LA PRENSA. EL MANDO DE ESTE SE EFECTUA POR UN DISTRIBUIDOR DE CORREDERA (16) QUE GIRA POR LA ACCION DE UN MOTOR (22) GOBERNADO, A SU VEZ, POR UN MODULO DE MANDO ELECTRONICO (24). EL DISTRIBUIDOR DE CORREDERA PUEDE DESPLAZARSE LIGERAMENTE EN LA DIRECCION DE SU EJE, LO QUE PERMITE, EN UNOS CASOS, QUE EL FLUIDO HIDRAULICO, IMPULSADO POR UNA BOMBA (32), PASE AL INTERIOR DE UNA CAMARA (40) SITUADA ENTRE LA PARTE SUPERIOR DEL GATO Y EL CUERPO DEL ELEVADOR Y LA PRENSA EJARZA SU FUERZA NOMINAL, Y, EN OTROS, QUE EL FLUIDO RETORNE A LA CUBETA DE ALMACENAMIENTO (36) CUANDO EL GATO ASCIENDE. EXISTEN DIFERENTES ALTERNATIVAS CONSTRUCTIVAS.
