Abstract

Изобретение относитс к судостроению и судоремонту и позвол ет снизить трудоемкость работ по демонтажу и монтажу гребных валов с винтами Дл этого используетс устройство, которое выполнено с подвижной платформой 2, причем на последней смонтирована тележка 6 с возможностью ее продольного перемещени по платформе 2, а на тележке 6 смонтировано основание 7 с возможностью поперечного перемещени по тележке 6 На основании 7 установлена подвижна в вертикальном направлении постель 8 дл укладки винта 9, смонтированного на валу 10В носовой части платформы 2 смонтированы домкраты 1 с опорами 11 и ролик 5 закрепленный с возможностью вертикального перемещени . На кормовом участке платформы 2 также установлены домкраты 1 с опорами 11 Дл демонтажа вала 10 платформу 2 по рельсам подвод т к валу 10, фиксируют, выравнивают ее положение подвод т тележку 6 под винт 9 Постель 8 поднимают Винт 9 креп т на этой постели и тележку 6 перемещают назад После прохождени тележки 6 над роликом 5 последний поднимают и создают упор между ним и валом 10 Затем винт 9 и вал 10 фиксируют на платформе 2 а последнюю затем вывод т 2 илThe invention relates to shipbuilding and ship repair and reduces the laboriousness of disassembling and assembling propeller shafts with screws. To do this, use a device that is made with a movable platform 2, with the trolley 6 mounted on the latter with the possibility of its longitudinal movement on the platform 2, and on the cart 6, the base 7 is mounted with the possibility of lateral movement along the carriage 6 On the base 7, a bed 8 is installed movable in the vertical direction for placing a screw 9 mounted on the shaft 10B of the bow parts of platform 2 are mounted jacks 1 with supports 11 and roller 5 fixed with the possibility of vertical movement. On the aft section of platform 2, jacks 1 with supports 11 are also installed. To remove shaft 10, platform 2 is guided along the rails to shaft 10, fixed, level its position, brings trolley 6 under screw 9 Bed 8 lifts screw 9 fixed on this bed and trolley 6 move back After the passage of the carriage 6 over the roller 5, the latter is lifted and an emphasis is placed between it and the shaft 10 Then the screw 9 and the shaft 10 are fixed on the platform 2 and the last is then pulled out
