[0031] 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 number 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 the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0032] As Figure 1 and Figure 2 shown, a boat recovery / launching device based on a stern gantry crane of the present application includes a boat recovery cage 3, a pair of anti-sway traction assemblies 4, and a stern gantry crane 2 mounted on a mother ship 1.

[0033] Among them, the stern gantry crane 2 needs to have sufficient lifting capacity to lift the boat recovery cage 3 and the unmanned boat. It can rotate in a direction parallel 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 stern gantry crane 2. The stern gantry crane 2 is used to hang the boat recovery cage 3 in the recovery / deployment sea area behind the mother ship 1. When recovering or deploying the unmanned boat, the navigation direction of the boat recovery cage 3 is always in a straight line with the heading of the mother ship 1.

[0034] In order to enhance the stability of the boat recovery cage 3 during lifting, the mother ship 1 is also provided with a pair of anti-sway traction assemblies 4, which are respectively connected to the two sides of the boat recovery cage 3. Under the traction force of the anti-sway traction assemblies 4 on both sides, the left and right shaking and swinging of the boat recovery cage 3 are reduced, ensuring the smooth recovery and deployment operations. Specifically, the anti-sway traction assembly 4 includes an anti-sway traction rope 41, an anti-sway traction device 42 and a pulley. Among them, the anti-sway traction device 42 is used to provide traction, and can specifically be a hydraulic / electric winch, which is installed on the mother ship 1 or the stern gantry crane 2. One end of the anti-sway traction rope 41 is connected to one side of the boat recovery cage 3, and the other end of the anti-sway traction rope 41 is tensioned and connected to the anti-sway traction device 42. The anti-sway traction rope 41 is tensioned by the anti-sway traction device 42 to pull the boat recovery cage 3 to one side. In order to realize the redirection of the traction force from the anti-sway traction device 42 to the boat recovery cage 3, the anti-sway traction rope 41 needs to be wound around the pulley to guide the traction direction of the anti-sway traction device 42 to traction toward one side of the boat recovery cage 3.

[0035] In one embodiment of the present application, the stern gantry crane 2 includes a turning seat 21, a telescopic arm 22 and a crossbeam 23. Specifically, a group of turning seats 21 and telescopic arms 22 are respectively provided at both ends of the crossbeam 23, thereby forming a portal basic frame. The turning seat 21 is rotatably connected to the mother ship 1, so as to realize the transportation of the boat recovery cage 3 and the unmanned boat. The first end of the telescopic arm 22 is telescopically connected to the turning seat 21. When the lifting height of the stern gantry crane 2 is not enough, the lifting height of the stern gantry crane 2 can be increased by extending the telescopic arm 22. The crossbeam 23 is connected to the second end of the telescopic arm 22.

[0036] In one embodiment of the present application, the pulley includes a fixed pulley 43, which is installed on the stern gantry crane 2 and is located on the side of the boat recovery cage 3, and the anti-sway traction rope 41 is wound around the fixed pulley 43. The fixed pulley 43 is used to change the traction direction of the anti-sway traction device 42, and the traction force is transmitted to the boat recovery cage 3 through the steering of the fixed pulley 43, so that the boat recovery cage 3 is tightened in the left and right directions, offsetting the left and right swaying and shaking of the boat recovery cage 3, thereby improving the stability of the boat recovery cage 3 during the lifting process.

[0037] In one embodiment of the present application, the anti-sway traction rope 41 includes a first anti-sway traction rope 411 and a second anti-sway traction rope 412. The first end of the first anti-sway traction rope 411 is connected to the left side of the boat recovery cage 3, and the first end of the second anti-sway traction rope 412 is connected to the right side of the boat recovery cage 3. The first anti-sway traction rope 411 and the second anti-sway traction rope 412 pull the left and right sides of the boat recovery cage 3 respectively, which strengthens the system rigidity when the boat recovery cage 3 is lifted, and effectively reduces the left and right swaying and shaking of the boat recovery cage 3.

[0038] In one embodiment of the present application, the anti-sway traction device 42 includes a first anti-sway traction device 421 and a second anti-sway traction device 422. The second end of the first anti-sway traction rope 411 is tensioned and connected to the first anti-sway traction device 421, and the first anti-sway traction device 421 provides traction for the first anti-sway traction rope 411; the second end of the second anti-sway traction rope 412 is tensioned and connected to the second anti-sway traction device 422, and the second anti-sway traction device 422 provides traction for the second anti-sway traction rope 412. The first anti-sway traction device 421 and the second anti-sway traction device 422 are independent of each other in structure and do not interfere with each other in operation. Therefore, the tension of the traction rope on either side of the boat recovery cage 3 can be adjusted separately according to actual needs, so that the boat recovery cage 3 is always in a centered state, reducing the tilt and shaking of the boat recovery cage 3.

[0039] In one embodiment of the present application, the boat recovery / deployment device based on the stern gantry crane also includes a heading traction rope 5 and a heading traction device 6. Among them, the heading traction device 6 is carried on the mother ship 1 and is located directly in front of the boat recovery cage 3; the first end of the heading traction rope 5 is connected to the heading traction device 6, and the second end of the heading traction rope 5 is connected to the front end of the boat recovery cage 3. When the mother ship 1 sails forward, it drives the heading traction device 6 to move forward, and the heading traction device 6 tows the heading traction rope 5 and the boat recovery cage 3 forward along the same heading. Compared with the method of towing the boat recovery cage 3 on one side of the mother ship 1, the heading traction device 6 of the present application only needs to bear the tension from the boat recovery cage 3, and will not generate torque from the boat recovery cage 3. Therefore, the heading traction device 6 can be specifically a hydraulic / electric winch.

[0040] In an embodiment of the present application, the boat recovery cage 3 includes a top frame, a left side frame, a right side frame, and a bracket. Specifically, a plurality of lifting rings are provided on the top frame for connection with the stern gantry crane 2. The left side frame and the right side frame are respectively connected to the left and right sides below the top frame, and the bracket is connected below the left side frame and the right side frame; the top frame, the left side frame, the right side frame, and the bracket enclose a receiving space for accommodating the boat, and the tail end of the boat recovery cage 3 has an opening communicating with the receiving space. To provide better protection for the unmanned boat, the left side frame and the right side frame respectively extend along the side hull contour direction of the unmanned boat, so as to better fit the unmanned boat, precisely support the side of the unmanned boat, and effectively reduce the external impact and damage that the unmanned boat may suffer during hoisting and handling. However, it should be noted that an appropriate gap should be reserved between the left side frame and the right side frame and the unmanned boat to facilitate the smooth entry and exit of the unmanned boat into and out of the receiving space.

[0041] In an embodiment of the present application, the first end of the first anti-sway towing rope 411 is specifically connected to the left side frame, and the first anti-sway towing rope 411 pulls the left side frame to the left. The first end of the second anti-sway towing rope 412 is specifically connected to the right side frame, and the second anti-sway towing rope 412 pulls the right side frame to the right.

[0042] In an embodiment of the present application, the second end of the course towing rope 5 is connected to the front end positions of the left side frame and the right side frame, so that the traction force received by the boat recovery cage 3 is consistent with the sailing direction of the boat recovery cage 3, so as to prevent the boat recovery cage 3 from rolling and swaying in the water.

[0043] In an embodiment of the present application, the boat recovery / launching device based on the stern gantry crane further includes a sling 8. One end of the sling 8 is connected to the top frame, specifically hung in the lifting rings on the top frame. The other end of the sling 8 is hung on the cross beam 23 of the stern gantry crane 2. A plurality of slings 8 can be provided to form a plurality of connection points on the top frame and the cross beam 23, so as to disperse the loads received on the top frame and the cross beam 23 and avoid stress concentration. The sling 8 and the lifting ring as well as the sling 8 and the cross beam 23 can be specifically connected by a buckle, which not only ensures that the sling will not accidentally fall off during hoisting, but also facilitates the disassembly work after hoisting.

[0044] When the boat recovery / launching device based on the stern gantry crane provided by the present application is in operation,

[0045] On the deck of the mother ship 1, one end of the sling 8 is hung on the lifting ring of the top frame of the boat recovery cage 3, and the other end is hung on the cross beam 23.

[0046] Then, the first anti-sway towing rope 411 is successively wound around the first fixed pulley 43 and the second fixed pulley 44 located on the left side of the boat recovery cage 3 from the first anti-sway towing device 421 until it is bound to the left frame; the second anti-sway towing rope 412 is successively wound around the first fixed pulley 43 and the second fixed pulley 44 located on the right side of the boat recovery cage 3 from the second anti-sway towing device 422 until it is bound to the right frame; finally, the course towing rope 5 is bound to the front end positions of the left frame and the right frame.

[0047] After that, start the stern gantry crane 2 to lift the boat recovery cage 3 and transfer it to a predetermined sea area behind the mother ship 1. The first anti-sway towing device 421 and the second anti-sway towing device 422 simultaneously and respectively tighten the first anti-sway towing rope 411 and the second anti-sway towing rope 412 to reduce the left-right swaying and swinging of the boat recovery cage 3.

[0048] Slowly lower the boat recovery cage 3 to the sea surface, and the course towing rope 5 and the course towing device 6 tow the boat recovery cage 3 to travel along the same navigation direction of the mother ship 1. After the unmanned boat enters or leaves the boat recovery cage 3, then lift the boat recovery cage 3 back onto the deck of the mother ship 1 again.

[0049] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
