Abstract

Un sistema de ensamble de culata para un martillo de fondo (DTH) que se opera por una alimentacion de fluido comprimido, que comprende principalmente una culata, dicha culata que tiene una perforacion central capaz de transportar el aire presurizado al martillo y un cilindro interno que se dispone coaxialmente y que se acopla con los medios de retencion liberables a la culata, donde dicha culata tiene una cavidad frontal interior y dichos medios de retencion liberables se encuentran en la cavidad frontal que se menciono. El martillo comprende, ademas, una camisa de desgaste que se dispone coaxialmente a la culata y al cilindro interno, en donde la culata se acopla al lado trasero de la camisa de desgaste. En ambas realizaciones de la presente invencion la camisa interna tiene una seccion trasera de menor diametro y un lado frontal de mayor diametro; ambas secciones se unen a traves de una porcion de diametro generalmente creciente.
