Изобретение относитс к судостроению , в частности к устройствам дл монтажа и демонтажа судовых гребных валов.The invention relates to shipbuilding, in particular, to devices for mounting and dismounting ship propeller shafts.

Известно устройство дл монтажа и демонтажа судовых гребных валов, содержащее подвижную платформу, на которой установлена подвижна тележка с винтовыми опорами, оборудованна т говой лебедкой 1.A device for mounting and dismounting ship propeller shafts is known, comprising a movable platform on which a movable carriage with screw supports is mounted, equipped with a traction winch 1.

Недостатком этого устройства вл етс то, что оно не обеспечивает должного качества работ, ограничивает технолгические операции при выполнении работ, что вли ет на трудоемкость монтажа и демонтажа гребных валов.A disadvantage of this device is that it does not ensure the proper quality of work, limits technological operations during work, which affects the laboriousness of the installation and disassembly of the propeller shafts.

Цель изобретени - повышение технологических возможностей устройства и снижение трудоемкости работ.The purpose of the invention is to increase the technological capabilities of the device and reduce the complexity of the work.

Поставленна цель достигаетс тем, что подвижна тележка снабжена шарнирно .установленными на вертикальной оси кронштейнами с гайками, барабанами с тросами и стопорными гайками, барабанами с тросами и стопорными гайками, жестко закрепленными на кронштейнах и торцах подвижной тележки , а барабаны смонтированы на винтовых опорах, причем последние ввернуты в гайках с возможностью вертйКального перемещени , при движении тележки , а свободные концы тросов закреплены на .платформе.The goal is achieved by the fact that the movable carriage is equipped with articulated brackets on the vertical axis with nuts, drums with cables and lock nuts, drums with cables and lock nuts fixed on the brackets and ends of the movable trolley, and the drums are mounted on screw supports the latter are screwed into the nuts with the possibility of skidding, when the trolley is moving, and the free ends of the cables are fixed on the platform.

Кроме того, шарнирно поворотные кронштейны выполнены с возможностью фиксации с помощью витков, ввернутых в стопорные гайки.In addition, the pivotally hinged brackets are made with the possibility of fixation with the help of turns, screwed into the lock nuts.

На фиг. 1 изображено устройство, вид сбоку на фиг. 2 - вид А на фиг.1; на фиг. 3 - схема работы устройства дл автоматического поддержани заданного угла наклона вала при подъеме опоры.FIG. 1 shows a side view of FIG. 2 is a view A in FIG. in fig. 3 is a diagram of the operation of the device for automatically maintaining a predetermined angle of shaft inclination when lifting the support.

Устройство дл монтажа и демонтажа судовых гребных валов состоит из подвижной платформы 1, на которой установлена подвижна тележка 2, оборудованна шарнирно поворотным кронштейном 3, шарнирно установленными на вертикальной оси кронштейнами 3, лебедкой 4 с тросом 5. На кронштейнах 3 жестко смонтированы гайки 6, в которые ввернуты винтовые опоры 7, на которые установлены барабаны 8 с тросами 9, маховик 10 и гребной вал 11. Настройка кроиштеинов осуществл етс с помощью винтов 12, ввернутых в стопорные гайки 13.The device for mounting and dismounting ship propeller shafts consists of a movable platform 1 on which a movable carriage 2 is installed, equipped with a pivotally pivoting bracket 3, pivotally mounted on a vertical axis brackets 3, a winch 4 with a cable 5. On brackets 3, nuts 6 are rigidly mounted screwed supports 7, on which drums 8 with cables 9, flywheel 10 and propeller shaft 11 are mounted. Adjustment of the croisteins is carried out with the help of screws 12 screwed into lock nuts 13.

Claims

30 The operation of the device during the dismantling of the shaft is carried out as follows. The trolley 2 is winched 4 with the help of a cable 5 fixed on the platform moving on the platform and leading up to the propeller shaft 11. The precise installation of the screw supports 7 along the axis of the shaft is accomplished by aligning the bracket 3 with screws 12. The shaft is fixed on the supports. The end of the cable is fixed to the drum 8 on the platform 1. With the winch 4 using the cable 5, the carriage moves along the platform together with the shaft. The cable 9, winding up from the drum 8 when the trolley is moving, rotates the screw support 7 in the nut 6. The support lowers, creating the necessary angle of inclination of the ridge shaft 11. The mounting of the propeller shaft 11 works in the reverse order. The positive effect of using the proposed device is that it eliminates the work to eliminate the deformation of the green shaft and the work to restore the protective coating of the propeller shaft, which gives an economic effect from saving materials, reducing the labor intensity and cost of the work being done, and also increases the quality of work bots. Claims of the invention. 1. Device for mounting and dismounting ship propeller shafts, comprising a movable platform on which the movable carriage with screw supports is stopped. Equipped with a traction winch, characterized in that, in order to increase the technological capabilities of the device and reduce the labor intensity of installation and dismantling of works, the movable trolley is equipped with articulated brackets on the vertical axis with nuts, drums with cables and lock nuts fixed on the brackets and ends of the movable trolley , the drums are mounted on screw supports, the latter are screwed into the nuts with the possibility of vertical movement, and the loose horses of the CROWS are fixed on the platform.

2. The device according to claim 1, characterized in that the co-inserts are made with the possibility of fixing with the help of screws, screwed into the ax nuts. Sources of information, rintye into account for the examination. 1. USSR author's certificate 227876, cl. In 63 to 9/00, 1968.
