Abstract

"DISPOSIçãO INTRODUZIDA EM PERFURATRIZ HIDRáULICA". Compreendendo um cilindro do reversor (1), cuja extremidade anterior é prolongada com um cabeçote intermediário (2), seguido por um cabeçote dianteiro (3) e respectivos parafusos de fixação (4), seguindo-se um outro cilindro definido como do mandril (5), já que em seu interior está alojado o mandril propriamente dito (6), cujo diâmetro externo recebe buchas (7) e gaxetas (8), ficando entre estas duas últimas um canal anelar interno (9) de circulação de um líquido refrigerante qualquer, como também neste ponto o mandril é vazado por furo transversal (10) e longitudinal (11) de circulação do dito refrigerante, sendo que, ainda, dito mandril (6) apresenta a sua extremidade distal com uma configuração (12), uma gaxeta (13) e um raspador (14), enquanto pelo lado oposto ou extremidade interna apresenta outra configuração (15) de acoplamento para uma haste (16) giratória e de impacto (martelete) que se estende até a outra extremidade do cilindro (1), onde está montado o bloco distanciador (17) seguido pela caixa de engrenagens (18) e sua tampa (19), ficando contra esta última um flange distanciador tubular (20) que, finalmente é prolongado por um cilindro (21), onde está montado o conjunto martelete (22) e respectivo pistão (23), o qual atua intermitentemente contra a extremidade superior da haste (16) que, ainda, além do movimento de martelete (impacto), também é giratoriamente movimentada por um motor hidráulico lateral (24)."PROVISION INTRODUCED IN A HYDRAULIC DRILL". Comprising a reversing cylinder (1), the front end of which is extended with an intermediate head (2), followed by a front head (3) and the respective fixing screws (4), followed by another cylinder defined as the mandrel ( 5), since the chuck itself (6) is housed inside it, the outer diameter of which receives bushings (7) and gaskets (8), between the latter two being an internal ring channel (9) for the circulation of a coolant any, as well as at this point the mandrel is poured through a transverse (10) and longitudinal (11) hole for the circulation of said refrigerant, and also said mandrel (6) presents its distal end with a configuration (12), a gasket (13) and a scraper (14), while on the opposite side or inside end it has another coupling configuration (15) for a rotating and impact rod (16) that extends to the other end of the cylinder (1 ), where it is mounted the spacer block (17) followed by the gearbox (18) and its cover (19), with a tubular spacer flange (20) against it, which is finally extended by a cylinder (21), where the hammer assembly is mounted (22) and respective piston (23), which acts intermittently against the upper end of the rod (16) which, in addition to the hammer movement (impact), is also rotated by a lateral hydraulic motor (24).
