The invention relates to a marine stern ramp retracting and releasing device and a synchronous retracting and releasing method.The retracting and releasing device is installed on the inner side bulkhead of a left board and the inner side of a right board of a cabin, and a transmission device serves as a power source, is composed of a variable frequency motor, a coupler, a speed reducer and a driving chain wheel and is installed on a deck platform on the front portion of the cabin; a driving chain wheel at the output end of the speed reducer drives the chain to reciprocate in a variable-frequency driving mode; a chain frame is arranged on a driving chain wheel and a driven chain wheel of the transmission device, the chain above the driving chain wheel and the driven chain wheel is connected with a cable dragging sliding block, the upper chain is supported and guided through a guide rail, and the lower chain is supported through a bracket. The two side traction devices are symmetrically distributed, the controller is electrically connected with the variable frequency motor, a master-slave synchronous control mode is adopted to output power in a chain transmission mode, so that chains drag respective dragging cable sliding blocks to conduct speed synchronous movement, the dragging cable sliding blocks are connected with traction rings of the stern ramp through rigging and pulley blocks, and therefore synchronous retracting and releasing of the two ends of the stern ramp are achieved. The stern ramp retracting and releasing function is achieved.

    本发明涉及一种船用艉跳板收放装置及同步收放方法,该收放装置安装于船舱左、右舷内侧舱壁,传动装置作为动力源,由变频电机、联轴器、减速器、主动链轮组成,安装于船舱前部甲板平台,采用变频驱动方式通过减速器输出端的主动链轮带动链条往复运动;链条架设在传动装置的主动链轮和从动链轮上,主动链轮和从动链轮上方链条连接拖索滑块,由导轨对上方链条进行支撑、导向,由托架对下方链条进行支撑;两舷牵引装置对称分布,控制器电连接变频电机,采取主从同步控制方式分别以链传动形式输出动力使链条拖动各自拖索滑块进行速度同步运动,通过索具和滑轮组将拖索滑块和艉跳板的牵引环连接,从而实现对艉跳板两端的同步收放,实现艉跳板收放功能。
