Abstract

QUE COMPRENDE: A) TRES SENSORES, LOS CUALES DETECTAN Y GENERAN UNA PRIMERA, SEGUNDA Y TERCERA SENAL RESPECTIVAMENTE. EL PRIMER SENSOR DETECTA LA VELOCIDAD DE PENETRACION DE LA BARRENA Y COMPRENDE UN TRANSDUCTOR DE DESPLAZAMIENTO LINEAL, EL SEGUNDO SENSOR DETECTA UN PESO SOBRE LA BARRENA Y COMPRENDE UN TRANSDUCTOR DE PRESION O UNA CELDA DE CARGA; Y EL TERCER SENSOR DETECTA UNA CARGA DE PAR DE TORSION APLICADA AL TUBO DE LA BARRENA. DICHOS SENSORES COMPRENDEN: UN TRANSDUCTOR DE DESPLAZAMIENTO LINEAL, UN TRANSDUCTOR DE PRESION Y UNA CELDA DE CARGA; B) UN CONTROLADOR QUE COMPRENDE UN CONTROLADOR LOGICO PROGRAMABLE, EL CUAL ESTA COMUNICADO ELECTRICAMENTE CON LOS SENSORES RESPECTIVOS Y CON LA SERVOVALVULA, A FIN DE CONTROLAR EL SISTEMA DE ACTIVACION. DICHO CONTROLADOR ES SENSIBLE A UNA DE LAS SENALES QUE TIENEN UN VALOR MAYOR AL VALOR MAXIMO RESPECTIVO PARA CONTROLAR EL SISTEMA DE ACTIVACION Y REDUCIR LA VELOCIDAD DE PENETRACION DE LA BARRENA; Y C) UN SISTEMA HIDRAULICO QUE COMPRENDE: MOTORES HIDRAULICOS CONECTADOS AL TUBO DE LA BARRENA Y UNA SERVOVALVULA
