The invention discloses a shipborne single-arm double-lifting-point adjustable small boat folding and unfolding device, and belongs to the technical field of ships. The device comprises an arm retracting and releasing structure, a suspension arm structure and two slings, one end of the arm retracting and releasing structure is installed on a ship deck and can overhang or retract relative to a ship, the other end of the arm retracting and releasing structure is hinged to one end of the suspension arm structure, a first fixed pulley is arranged on the arm retracting and releasing structure, and one end of a sling is wound and penetrates through the first fixed pulley to be connected with a small boat; the suspension arm structure can rotate vertically, a second fixed pulley is arranged at the other end of the suspension arm structure, and one end of the other suspension cable penetrates through the second fixed pulley in a winding mode to be connected with the small boat. By rotating the suspension arm structure, the connection position of the slings penetrating through the second fixed pulley in a winding mode and the small boat can be changed, and adjustment of the suspension distance formed by the two slings is achieved. The boat lifting stability is improved, the boat lifting distance can be adjusted, and the boat lifting safety, flexibility and convenience are guaranteed.

    本发明公开了一种船载单臂双吊点可调的小艇收放装置,属于船舶技术领域。装置包括收放臂结构、吊臂结构和两根吊索;收放臂结构的一端安装于船舶甲板上,且能够相对于船舶进行悬伸或者缩回,收放臂结构的另一端与吊臂结构的一端铰接,收放臂结构上设置有固定滑轮一,一条吊索的一端绕设穿过固定滑轮一与小艇连接;吊臂结构能够进行竖直转动,吊臂结构的另一端设置有固定滑轮二,另一条吊索的一端绕设穿过固定滑轮二与小艇连接;通过转动所述吊臂结构,能够改变绕设穿过固定滑轮二的吊索与小艇连接的位置,实现对两条吊索形成的吊间距的调节。本发明提高了起艇稳定性,能够调节起艇间距,保证起艇的安全性、灵活性与便利性。
