Abstract

LA INVENCION SE REFIERE A UN MARTILLO HIDRAULICO DE IMPACTO, PARTICULARMENTE A LA ESTRUCTURA DE ALOJAMIENTO DE UN MARTILLO HIDRAULICO DE IMPACTO, DICHA ESTRUCTURA COMPRENDE UN PISTON QUE FUNCIONA HIDRAULICAMENTE (7, 19) Y UN MIEMBRO (1, 11) PARA GUIAR EL PISTON, UN MIEMBRO DE IMPACTO (8, 20) Y UN MIEMBRO (2, 12) PARA GUIAR EL MIEMBRO DE IMPACTO. DICHA ESTRUCTURA SE ENCUENTRA ENCERRADA EN UNA CARCASA PROTECTORA (6, 18). DE ACUERDO CON LA INVENCION, EL MIEMBRO DE GUIA DEL PISTON (1, 11) Y EL MIEMBRO (2, 12) QUE GUIA EL MIEMBRO DE IMPACTO SE FABRICAN POR SEPARADO (3, 15) UNO CON RESPECTO AL OTRO PARA EVITAR QUE SE PRODUZCA UNA ONDA DE TENSION REFLEJADA DESDE EL MIEMBRO DE IMPACTO (8, 20). DE TODAS FORMAS, EL MIEMBRO DE GUIA DEL PISTON Y EL MIEMBRO DE GUIA DEL MIEMBRO DE IMPACTO ESTAN INTERCONECTADOS DE FORMA QUE EL MIEMBRO DE GUIA DEL PISTON Y EL MIEMBRO QUE GUIA EL MIEMBRO DE IMPACTO SE ENCUENTRAN CONECTADOS A AL MENOS UN ELEMENTO ATENUADOR (4,5; 14,16,17).THE INVENTION REFERS TO A HYDRAULIC IMPACT HAMMER, PARTICULARLY TO THE ACCOMMODATION STRUCTURE OF A HYDRAULIC IMPACT HAMMER, SUCH STRUCTURE COMPRISES A HYDRAULICALLY OPERATING PISTON (7, 19) AND A GUIDE MEMBER (1, 11) ONE IMPACT MEMBER (8, 20) AND ONE MEMBER (2, 12) TO GUIDE THE IMPACT MEMBER. THE STRUCTURE IS LOCATED IN A PROTECTIVE HOUSING (6, 18). ACCORDING TO THE INVENTION, THE PISTON GUIDE MEMBER (1, 11) AND THE MEMBER (2, 12) WHO GUIDE THE IMPACT MEMBER ARE MANUFACTURED SEPARATELY (3, 15) ONE WITH RESPECT TO THE OTHER TO PREVENT IT FROM PRODUCING A WAVE OF TENSION REFLECTED FROM THE IMPACT MEMBER (8, 20). IN ANY WAY, THE PISTON GUIDE MEMBER AND THE IMPACT MEMBER GUIDE MEMBER ARE INTERCONNECTED SO THAT THE PISTON GUIDE MEMBER AND THE GUIDE MEMBER OF THE IMPACT MEMBER ARE CONNECTED TO AT LEAST ONE ELEMENT , 5; 14,16,17).
