Abstract

FERRAMENTAL PARA TROCA DE VENTANEIRAS E CAIXAS DE REFRIGERAçãO. O objeto desta patente é um conjunto de dispositivos desmontável, portátil, operável por apenas dois operadores, em condições de alto nível de segurança, utilizável para reduzir o tempo médio de remoção de ventaneiras e caixas de refrigeração de altos-fornos de dezessete para sete horas, pela aplicação de forças de cerca de cem toneladas sobre as mesmas, através de macaco hidráulico. é de construção simples e robusta e possui ressalto (18), barra retangular longitudinal (13A), pinos de contenção (28), barra de suporte (21), com janela (22), berço (23), gaveta (24), com orificio (26), olhais (27), contra-berço (25), barra de posicionamento (16), com cunha (17), terminal (29), macaco hidráulico (33), barra longitudinal (13), dispositivo sacador (30) e barra de giro (34). O emprego do "FERRAMENTAL PARA TROCA DE VENTANEIRAS E CAIXAS DE REFRIGERAçãO" objeto desta patente reduz o tempo médiode operação de substituição de uma ventaneira e de sua caixa de refrigeração, de dezessete para sete horas, com significativa redução dos valores perdidos pela interrupção de produção conforme acima apontados e, além disto, minimiza os esforços fisicos dos operadores com notável aumento de segurança da operação.TOOL FOR REPLACING FAN AND COOLING BOXES. The object of this patent is a portable, detachable device assembly operable by only two operators under high safety conditions, usable to reduce the average removal time of blast furnaces and blast boxes from seventeen to seven hours , by applying forces of about one hundred tons on them, through hydraulic jack. It is of simple and robust construction and has shoulder (18), longitudinal rectangular bar (13A), retaining pins (28), support bar (21), with window (22), cradle (23), drawer (24), with hole (26), eyes (27), cot (25), positioning bar (16), with wedge (17), terminal (29), hydraulic jack (33), longitudinal bar (13), withdrawing device (30) and swivel bar (34). The use of the "FAN AND COOLING CHANGE TOOL" object of this patent reduces the average operation time of replacement of a fan and its cooling box, from seventeen to seven hours, with a significant reduction in the values lost due to production interruption. as noted above, and furthermore minimizes the physical efforts of operators with a remarkable increase in operating safety.
