According to a ship launching method and a hydraulic variable-slope system thereof, a ship is borne on a ship row trolley, the ship row trolley is stopped and fixed to a variable-slope slide way, one end of the variable-slope slide way is hinged to a ground foundation shaft seat, the other end of the variable-slope slide way is a free rotation variable-amplitude end, and the free rotation end can be connected with an inclined slide way; the load point of the lower plane of the variable-slope slide way steel structure body is connected with a ball joint mechanism at the end of a piston of a hydraulic cylinder, and the bottom end of the cylinder body at the other end of the hydraulic cylinder is hinged to a foundation shaft pin base on the bottom face of a pit below. The invention is applied to a shipbuilding site with a large drop between a river bank and a river channel, the variable-slope slide way can be rotated and converted into a horizontal platform or an inclined slide way through the action of the hydraulic system, so that excessive site occupied by the slide way is reduced, and the purposes of saving the construction land of a shipbuilding factory and improving the ship launching operation efficiency are achieved.

    一种船舶下水方法及其液压变坡系统,船舶承载在船排小车上,船排小车停止固定在变坡滑道上,变坡滑道的一端铰接在地面基础轴座上,另一端为自由转动变幅端,自由转动端可衔接倾斜滑道;变坡滑道钢结构体下平面载荷点处与液压缸的活塞端部的球关节机构连接,液压缸另一端的缸体底端部铰接在下方的坑底面基础轴销座上。本发明应用在河岸与河道落差较大的船舶制造场地上,变坡滑道可通过液压系统的动作转动,变换成为水平平台或者倾斜滑道,从而减少了滑道占用过多场地,达到节约造船厂建设用地和提高船舶下水作业效率的问题。
