Abstract

UN PERNO PARA ROCAS AUTORROSCANTE QUE CONSTA DE UN PERFIL ROSCADO DISCONTINUO (9) QUE TIENE UNA PLURALIDAD DE SALIENTES DE CORTE (11) Y AL MENOS UNA RANURA (13) QUE SE EXTIENDE POR TODO LO LARGO DEL PERNO PARA ROCAS. LOS SALIENTES DE CORTE (11) ESTAN ADAPTADOS PAR CORTAR UN PERFIL ROSCADO FORMADO EN LA SUPERFICIE INTERIOR DE UN AGUJERO PILOTO DE MODO QUE EL PERFIL ROSCADO (9) DEL PERNO PARA ROCAS QUEDE INTERCONECTADO A EL. LA O CADA UNA DE LAS RANURAS (13) SE ENCUENTRA ADAPTADA PARA FACILITAR LA RETIRADA DEL MATERIAL CORTADO POR LOS SALIENTES DE CORTE (11). UN ASPECTO PREFERENTE DEL PERNO PARA ROCAS DE LA INVENCION INCLUYE UN AGUJERO AXIAL INTERIOR (25) PARA PERMITIR QUE SE PUEDA INYECTAR AGUA A TRAVES DEL PERNO PARA ROCAS Y MEDIDA QUE SE CORTA EL PERFIL ROSCADO. UN PERNO PARA ROCAS AUTORROSCANTE Y DE PERFORACION AUTOMATICA CONSTA DEL PERNO PARA ROCAS AUTORROSCANTE ARRIBA DESCRITO Y DE UN ELEMENTO DE CORTE (23) PARA CORTAR UN AGUJERO PARA EL PERNO PARA ROCAS.
