The stable lifting device for helicopter rescue comprises a base frame, the two sides of the interior of the base frame are each provided with two symmetrical screw rods, a rotating head is installed at one end of each screw rod, the rotating heads penetrate through the side wall of the base frame in a threaded mode and extend into the base frame to be connected with the screw rods, and a winding assembly is installed on the base frame; a connecting assembly is installed between the base frame and the winding assembly, a supporting assembly is installed on the winding assembly, the winding assembly is used for driving the supporting assembly to move so that the supporting assembly can ascend or descend, and the supporting assembly is used for supporting survivors. By rotating the rotating head, the screw rods move in the base frame, the four screw rods abut against the upper portion of the helicopter, the base frame is fixed to the helicopter, the winding assembly works, the supporting assembly descends, and after the supporting assembly descends to the lowest position, the survivor is supported through the supporting assembly; and the winding assembly drives the supporting assembly to ascend, so that the survivor ascends to a proper height, and the survivor is driven to move through the helicopter.
本发明公开了一种直升机救援用稳定升降装置,包括基架,基架的内部两侧均设有两个对称的螺杆,每个螺杆的一端安装有转头,转头螺纹贯穿基架的侧壁延伸至内部与螺杆连接,基架上安装有收卷组件,且基架与收卷组件之间安装有连接组件,收卷组件上安装有支撑组件,且收卷组件用于带动支撑组件移动,使支撑组件上升或下降,支撑组件用于支撑幸存者。本发明通过转动转头,使螺杆在基架中移动,通过四个螺杆抵住直升机上方,使基架固定于直升机上,通过收卷组件工作,使支撑组件下降,支撑组件下降至最低处后,通过支撑组件对幸存者支撑,当幸存者身形稳定后,使收卷组件带动支撑组件上升,使幸存者上升至合适高度,通过直升机带动幸存者移动。
