Abstract
UN SISTEMA (1) Y UN METODO PARA INSPECCIONAR A DISTANCIA LAS PAREDES (18) INTERNAS DE UNA CAVIDAD QUE TIENE UNA SECCION TRANSVERSAL CIRCULAR QUE VARIA EN DIAMETRO, TAL COMO EL INTERIOR DE UN OBTURADOR (3) DE TUBO HUECO. EL SISTEMA (1) COMPRENDE GENERALMENTE UNA CABEZA (11) DE SONDA O PROBETA DE CORRIENTE PARASITA, QUE TIENE EXTREMOS DISTANTE Y PROXIMO, DONDE EL EXTREMO DISTANTE SE ACOPLA CON LAS PAREDES (18) DE LA CAVIDAD, UN CONJUNTO (9) DE SOPORTE ALARGADO, CONECTADO AL EXTREMO PROXIMO DE LA PROBETA (11), QUE PUEDE INTRODUCIRSE DENTRO DE LA CAVIDAD, UN MECANISMO (29, 32, 34, 42) EXPANSOR RADIAL, PARA EXPANSIONARSE RADIALMENTE Y EXTRAYENDO EL EXTREMO DISTANTE DE LA PROBETA (11) CON RESPECTO AL EJE LONGITUDINAL DEL CONJUNTO (9) DE SOPORTE, Y UN SISTEMA (13) DE ENTREGA Y MOTRIZ DE LA PROBETA, PARA INTRODUCIR EL ELEMENTO (13) DE SOPORTE DENTRO DE LA CAVIDAD Y MOVER HELICOIDALMENTE LA CABEZA (11) DE LA PROBETA PARA INSPECCIONAR LAS PAREDES (18) DE LA CAVIDAD, A EFECTOS DE DISCONTINUIDADES O INFLEXIONES. EN EL METODO DE LA INVENCION, EL MECANISMO (13) EXPANSOR RETIRA RADIALMENTE LA CABEZA (11) DE LA PROBETA DENTRO DEL CONJUNTO (9) DE SOPORTE, CUANDO SE INTRODUCE A TRAVES DE LA CAVIDAD, CON ANTERIORIDAD A LA OPERACION DE INSPECCION, CON OBJETO DE EVITAR INTERFERENCIA MECANICA, Y DESPUES EXTIENDE RADIALMENTE LA CABEZA (11) DE LA PROBETA EN ACOPLAMIENTO CON LAS PAREDES (18) DE LA CAVIDAD. EL SISTEMA (13) DE ENTREGA Y MOTRIZ DE LA PROBETA MUEVE DESPUES HELICOIDALMENTE LA CABEZA (11) DE LA PROBETA A TRAVES DE LAS PAREDES (18) DE LA CAVIDAD, PARA EXPLORARLAS A EFECTOS DE DISCONTINUIDADES QUE INDICAN FISURAS U OTRAS IMPERFECCIONES EN LAS PAREDES (18).
