Abstract

"CONJUNTO DE TRAVAMENTO PARA TRAVAR UM ELEMENTO TUBULAR EXTERNO EM UM ELEMENTO TUBULAR INTERNO". Um conjunto de travamento (1) para travar um elemento tubular externo em um elemento tubular interno que se estende através do elemento tubular externo, o conjunto compreendendo um mandril de travamento (5) conectado a um dentre os referidos elementos tubulares e que é dotado de um recesso voltado para o outro dentre os referidos elementos tubulares, o recesso (10) tendo pelo menos uma superfície lateral divergente para dentro (12, 14), um componente de travamento (34) disposto entre o primeiro e o segundo elementos tubulares em uma relação de travamento com o outro dentre os elementos tubulares, o componente de travamento estendendo-se para o interior do referido recesso e sendo operável entre um modo retraído em que o componente de travamento é móvel em relação ao recesso e um modo expandido em que o componente de travamento é expandido contra a superfície lateral divergente para dentro, o conjunto compreendendo ainda um dispositivo atuador para expandir o componente de travamento no interior do referido recesso contra a referida superfície lateral divergente."LOCKING ASSEMBLY TO LOCK AN EXTERNAL TUBULAR ELEMENT INTO AN INTERNAL TUBULAR ELEMENT". A locking assembly (1) for locking an external tubular element into an internal tubular element extending through the external tubular element, the assembly comprising a locking mandrel (5) connected to one of said tubular elements and which is provided with a recess facing the other among said tubular elements, the recess (10) having at least one side surface diverging inwards (12, 14), a locking component (34) disposed between the first and the second tubular elements in a locking relationship with the other among the tubular elements, the locking component extending into the said recess and being operable between a retracted mode in which the locking component is movable in relation to the recess and an expanded mode in which the the locking member is expanded against the diverging inward side surface, the assembly further comprising an actuating device for expanding the locking member locking inside said recess against said diverging side surface.
