Abstract
UN DISPOSITIVO PARA ENSANCHAR UN TUBO (70) COMPRENDE UNA SONDA (2) QUE SE INTRODUCE EN EL TUBO (70) Y QUE TIENE UN MANGUITO ELASTICO DE EXPANSION (4) QUE ES IMPULSADO, AL MENOS EN PARTE DE SU SUPERFICIE INTERIOR, CON UN MEDIO DE PRESION. SEGUN LA INVENCION, EL MANGUITO DE EXPANSION (4) LLEVA MONTADO EN SU PERIMETRO EXTERIOR UN ANILLO DE SOPORTE (50) QUE SE APOYA EN UNA ESPALDILLA (51A, B) DE LA SONDA (2) QUE RODEA EL MANGUITO DE EXPANSION (4) Y QUE ESTA FORMADA POR DOS SEGMENTOS MOVILES UNO EN RELACION CON EL OTRO. CON ESTA MEDIDA SE GARANTIZA QUE EL ANILLO DE SOPORTE (50) PUEDA SEGUIR LA VARIACION DE DIAMETRO QUE TIENE LUGAR DURANTE EL ENSANCHAMIENTO DEL MANGUITO DE EXPANSION (4) Y RETORNE A SU POSICION INICIAL, DE MANERA QUE SE IMPIDA EL APLASTAMIENTO DEL MANGUITO DE EXPANSION (4) EN LA RENDIJA (S) EXISTENTE ENTRE EL TUBO (70) Y LA SONDA (2).A DEVICE FOR THREADING A TUBE (70) INCLUDES A PROBE (2) THAT INTRODUCES ITSELF IN THE TUBE (70) AND HAS AN ELASTIC EXPANSION SLEEVE (4) THAT IS DRIVEN, AT LEAST IN PART OF ITS INNER SURFACE, WITH A PRESSURE MEDIUM. ACCORDING TO THE INVENTION, THE EXPANSION SLEEVE (4) HAS MOUNTED ON ITS EXTERIOR PERIMETER A SUPPORT RING (50) THAT IS SUPPORTED ON A PROBE LEG (51A, B) SURROUNDING THE EXPANSION SLEEVE (4) AND THAT IT IS FORMED BY TWO MOBILE SEGMENTS, ONE IN RELATION TO THE OTHER. WITH THIS MEASURE, IT IS GUARANTEED THAT THE SUPPORT RING (50) CAN FOLLOW THE DIAMETER VARIATION THAT OCCURS DURING THE EXTENSION OF THE EXPANSION SLEEVE (4) AND RETURNS TO ITS INITIAL POSITION, SO THAT THE CRUSHING OF THE EXPANDING SLEEVE IS PREVENTED (4) IN THE EXISTING SLIT (S) BETWEEN THE TUBE (70) AND THE PROBE (2).
