Abstract

PERFECCIONAMIENTOS EN UN MECANISMO DE PROGRESION EXTERIOR PARA BASTIDORES HIDRAULICOS DE ENTIBACION.COMPRENDE DOS BARRAS DE GUIA DISPUESTAS A DISTANCIA LATERAL ENTRE SI Y DOS CILINDROS DE PROGRESION DISPUESTOS POR ENCIMA. LAS BARRAS DE GUIA ESTAN UNIDAS EN SU EXTREMO ANTERIOR EN UNA CABEZA DE BARRAS. A DISTANCIA POR DETRAS DE ESTA CABEZA DE BARRAS ESTAN UNIDOS CON AMBAS BARRAS DE GUIA UN PUENTE EN EL QUE ATACAN LOS DOS CILINDROS DE PROGRESION CON SUS VASTAGOS DE EMBOLO. LOS CILINDROS DE PROGRESION ESTAN UNIDOS CON LOS PATINES DEL YACENTE A DISTANCIA POR DETRAS, A TRAVES DE CONSOLAS DE CONEXION, CONSTITUYENDO LAS CONSOLAS DE CONEXION GUIAS PARA LAS BARRAS DE GUIA.
