Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of rescue helicopter accessories, and in particular relates to a stable lifting device for helicopter rescue. Background technique [0002] Rescue helicopter is the application of helicopters in emergency rescue. It can reach the work site inaccessible by water and land more quickly, and carry out search and rescue, material delivery, air command and other tasks. It is the most effective emergency rescue commonly used by many countries in the world. When rescuing survivors, a hoist is required. [0003] However, when the existing lifting device is installed, it can only be used in conjunction with a fixed type of helicopter. The scope of use of the device is limited, and when there is no need to rescue survivors, because the lifting device is installed at the bottom of the helicopter, the passability of the helicopter is greatly reduced. Therefore, When the rescue work is not performed, the lifting device n...
