Stern rope ring unfolding, hanging and dragging traction device

Abstract

The invention discloses a stern rope ring unfolding, hanging and dragging traction device which can quickly establish connection between a mother ship and a recovery target so as to pull a recovery target and assist in laying the target. The device comprises a traction rope, left and right traction rods, a rope guide device, a releaser and a winch. The traction rope is released by the winch, thenpenetrates through the rope guide device, is positioned at the tail end of the left traction rod, then is wound to the tail end of the right traction rod and finally is fixed to the releaser after passing through the rope guide device, and therefore a U-shaped rope loop is formed on the water surface of the stern. During use, a recovered object carries a hook to enter the rope ring, the hook is used for hooking the rope ring, and the rope ring is separated from the tail ends of the left traction rod and the right traction rod under the traction action of the recovery target and is closed underthe limitation of the rope guide device, so that dragging of the recovery target is realized. When a target is placed, the closed rope loop is hung on the hook of the target, and the target is tensioned to stably enter water. After the target enters the water, the releaser releases the traction cable, and the traction cable is pulled back to be separated from the hook on the target to finish laying.

Description

technical field [0001] The invention relates to a traction device, in particular to a stern rope loop unfolding hook traction device. Background technique [0002] When water surface targets such as craft or small boats are recovered on the water surface, in order to establish a connection between the mother ship and the recovery target, the common method is to accurately control the relative position between the mother ship and the target, and the crew use fishing rods and other equipment to recover the target. Establish a connection with the mother ship. This method requires the mother ship and the target to adjust the relative position and course in real time at a low speed, and requires the operator to connect on the side of the ship or even to the water surface. Contents of the invention [0003] In view of this, the present invention provides a stern rope loop deployment hooking and pulling device, which can quickly establish a connection between the mother ship and...
