[0040] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more unless otherwise specifically defined.

[0041] Such as Figure 1 and Figure 2As shown, the present application provides a boat recovery / deployment device based on a ship-borne folding arm crane, comprising a boat recovery cage 3, an anti-sway traction rope 4, an anti-sway traction device 5 and a folding arm crane 2 carried on a mother ship 1.

[0042] Among them, the folding arm crane 2 can specifically be a large-scale hydraulic folding arm crane on board a ship, which has sufficient lifting capacity to lift the boat recovery cage 3 and the unmanned boat. The folding arm crane 2 can also rotate in a direction perpendicular to the deck of the mother ship 1 to move the boat recovery cage 3 to a predetermined position. The unmanned boat is loaded on the boat recovery cage 3, and the boat recovery cage 3 is suspended on the folding arm crane 2. The folding arm crane 2 is used to suspend the boat recovery cage 3 in the recovery or deployment sea area on one side of the mother ship 1; when recovering or deploying the unmanned boat, the boat recovery cage 3 is always located on one side of the mother ship 1, and the long axis direction of the boat recovery cage 3 remains parallel to the heading of the mother ship 1.

[0043] In order to enhance the stability of the boat recovery cage 3 under complex sea conditions, one end of the anti-sway traction rope 4 is connected to the boat recovery cage 3 to form traction on the boat recovery cage 3. The anti-sway traction device 5 is installed on the folding arm crane 2 and is tensionedly connected to the other end of the anti-sway traction rope 4. The anti-sway traction device 5 is a component that provides traction force, and specifically can be a hydraulic / electric winch, etc. The traction force provided by the anti-sway traction device 5 pulls the boat recovery cage 3 to the side close to the mother ship 1, thereby effectively reducing the sway and shaking amplitude of the boat recovery cage 3, ensuring the smooth recovery and deployment operations.

[0044] like Figures 1 to 5 As shown, in one embodiment of the present application, the anti-sway traction rope 4 includes a first anti-sway traction rope 41 and a second anti-sway traction rope 42. Specifically, the first end of the first anti-sway traction rope 41 is connected to the boat recovery cage 3 to directly tow the boat recovery cage 3. The first end of the second anti-sway traction rope 42 is connected to the hook 21 of the folding arm crane 2 to indirectly limit the sway and shaking of the boat recovery cage 3 by towing and limiting the sway and shaking of the hook 21. Through the cooperation of the first anti-sway traction rope 41 and the second anti-sway traction rope 42, not only the distribution of traction force is optimized, but also the size and direction of traction force can be more flexibly adjusted during operation to cope with various shaking conditions that may occur in the recovery cage 3 under different sea conditions.

[0045] like Figure 3As shown, in one embodiment of the present application, the anti-sway traction device 5 includes a first anti-sway traction device 51 and a second anti-sway traction device 52. Among them, the second end of the first anti-sway traction rope 41 is tensioned and connected to the first anti-sway traction device 51, and the first anti-sway traction device 51 provides traction force for the first anti-sway traction rope 41, ensuring that the swaying and shaking of the boat recovery cage 3 can be effectively suppressed during the lifting process. The second end of the second anti-sway traction rope 42 is tensioned and connected to the second anti-sway traction device 52, and the second anti-sway traction device 52 provides traction force for the second anti-sway traction rope 42, ensuring that the swaying and shaking of the hook 21 can be suppressed. The first anti-sway traction device 51 and the second anti-sway traction device 52 are independent of each other in structure and do not interfere with each other in operation. Therefore, the tension of any traction rope can be adjusted separately according to actual needs without worrying about affecting the other traction rope.

[0046] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the boat recovery / laying device based on the ship-borne folding arm crane also includes a heading traction rope 6 and a heading traction device 7. Among them, the heading traction device 7 is carried on the mother ship 1, the first end of the heading traction rope 6 is connected to the heading traction device 7, and the second end of the heading traction rope 6 is connected to the front end of the boat recovery cage 3. The heading traction device 7 is used to pull the direction of the boat recovery cage 3 so that the long axis direction of the boat recovery cage 3 is always parallel to the heading of the mother ship 1. Since the traction force in the direction of pulling the boat recovery cage 3 is much smaller than the self-gravity of the boat recovery cage 3, the heading traction device 7 can be specifically a small hydraulic folding arm crane arranged on the side of the mother ship 1. In addition, the heading traction device 7 must also have the ability to rotate around a direction perpendicular to the deck of the mother ship 1, so that it can follow the moving trajectory of the boat recovery cage 3 during the recovery or laying process, and adjust its traction angle in real time to match the optimal traction adaptation angle.

[0047] In one embodiment of the present application, the boat recovery cage 3 includes a top frame, a side frame and a bracket arranged in sequence from top to bottom. Specifically, a plurality of lifting rings are provided on the top frame so as to be connected to the folding arm crane 2. The side frames are arranged on the left and right sides below the top frame, and the bracket is connected below the side frames on the left and right sides. The top frame, the side frame and the bracket enclose a storage space for accommodating the boat. The tail end of the boat recovery cage 3 has an opening connected to the storage space. In order to provide better protection for the unmanned boat, the side frame extends along the side profile direction of the unmanned boat, so that it can better fit the unmanned boat, accurately support the side of the unmanned boat, and effectively reduce the external impact and damage that the unmanned boat may suffer during the lifting and handling process. However, it should be noted that an appropriate gap should be retained between the side frame and the unmanned boat so that the unmanned boat can smoothly enter or exit the storage space.

[0048] like Figure 1 and Figure 2As shown, in one embodiment of the present application, the boat recovery / laying device based on the ship-borne folding arm crane also includes a plurality of slings 8, one end of each sling 8 is connected to the top frame, and is specifically hung in the lifting ring on the top frame. The other end of each sling 8 is hung on the hook 21 of the folding arm crane 2. The load on the top frame can be dispersed by multiple slings 8 to avoid stress concentration. The sling 8 and the lifting ring and the sling 8 and the hook 21 can be connected by a lock buckle, which not only ensures that the sling will not fall off accidentally during the lifting process, but also facilitates the disassembly work after lifting.

[0049] In one embodiment of the present application, the first end of the first anti-sway traction rope 41 is connected to the side frame facing the mother ship 1 to facilitate pulling the boat recovery cage 3 toward the side close to the mother ship 1.

[0050] In one embodiment of the present application, the second end of the heading towing rope 6 is connected to the front end position of the side frame, so that the boat recovery cage 3 can be kept sailing parallel to the mother ship 1 without providing additional navigation power to the boat recovery cage 3.

[0051] In one embodiment of the present application, when the folding arm crane 2 lifts the boat recovery cage 3 off the deck of the mother ship 1, the anti-sway traction rope 4 is adjusted to a tensioned state, and a stable mechanical balance system is constructed through the pre-tensioned anti-sway traction rope 4, which effectively offsets and absorbs the sway and shaking of the boat recovery cage 3 caused by factors such as wind, waves or its own inertia during the ascent process. The anti-sway traction rope 4 pulls the boat recovery cage 3 to a certain tension anti-sway angle with the vertical direction.

[0052] In one embodiment of the present application, the angle range of the tension anti-sway angle is 2°-3°. Within this angle range, the anti-sway ability of the boat recovery cage 3 can be significantly improved. When it is less than this angle range, the anti-sway ability of the boat recovery cage 3 is improved less, and the swing and shaking of the boat recovery cage 3 are still large; when it is greater than this angle range, the load on the anti-sway traction rope 4 is large, and the anti-sway ability of the boat recovery cage 3 is further improved less. In general sea conditions, this angle range can not only meet the anti-sway ability requirements of the boat recovery cage 3, but also be the most economical and efficient.

[0053] The boat recovery / deployment device based on the ship-borne folding arm crane provided in the present application is used during operation.

[0054] On the deck of the mother ship 1 , one end of the sling 8 is hung on the sling ring of the top frame of the boat recovery cage 3 , and the other end is hung on the hook 21 .

[0055] Then, the first anti-sway traction rope 41 is tied to the side frame of the boat recovery cage 3, the second anti-sway traction rope 42 is hung on the hook 21 of the folding arm crane 2, and the heading traction rope 6 is tied to the front end position of the side frame.

[0056] Afterwards, the folding arm crane 2 is started to lift the boat recovery cage 3 and transfer it to the predetermined sea area on the side of the mother ship 1. The first anti-sway traction device 51 and the second anti-sway traction device 52 simultaneously tighten the first anti-sway traction rope 41 and the second anti-sway traction rope 42 respectively to reduce the sway and shaking of the boat recovery cage 3. The heading traction device 7 also moves with the position of the boat recovery cage 3 to adjust the traction adaptation angle at all times.

[0057] The boat recovery cage 3 is slowly lowered to the sea surface, and after the unmanned boat enters or leaves the boat recovery cage 3 , the boat recovery cage 3 is hoisted back onto the deck of the mother ship 1 .

[0058] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
