Description

Technical Field

[0001] The invention belongs to the field of boat retrieval and launching, and in particular relates to a cabin top translation type integrated boat retrieval and launching system. Background Art

[0004] The internal space layout of different types of existing ships varies greatly, and most ships do not have space reserved specifically for storing unmanned boats. In addition, since key structural parameters such as the spacing between the rudder shafts at the stern of the ship are fixed, and some ships have helicopter decks or other superstructures at the stern, it is difficult for these ships to increase the necessary storage area or install traditional forms of boat launching and retrieving devices through simple modifications. Although traditional side cranes or stern slides can be used for the launch and recovery of individual small boats, they are inefficient and unsafe for situations where multiple unmanned boats need to be handled at the same time. More importantly, considering the structural characteristics of many existing ships, as mentioned above, they cannot be equipped with such equipment at all. Even if some ships can theoretically be rebuilt on a large scale to meet the above requirements, the high cost investment often makes this solution unfeasible, especially for projects with a shorter expected service life or lower frequency of use, such a huge initial investment is obviously not cost-effective. Summary of the invention

[0005] The purpose of the present invention is to provide a cabin top translation type integrated boat retrieval and launching system to solve the technical problem of integrated arrangement in the area on the deck of a mother ship or in the cabin space and releasing and recovering unmanned boats through the side of the mother ship.

[0008] As a further improvement of the present invention, the rotating structure includes a rotating drive device connected to the walking support and a rotating support connected to the boom support; the rotating drive device drives the rotating support to rotate, thereby driving the boom support to rotate.

[0009] As a further improvement of the present invention, one end of the boom bracket is connected to the rotating bracket through a variable amplitude driving device, and the other end is connected to the capture structure. The middle part of the boom bracket is rotatably connected to the walking bracket, and the variable amplitude driving device drives the boom bracket to rotate relative to the rotating bracket.

[0010] As a further improvement of the present invention, the capture structure includes a hydraulic winch, an anti-sway device, and a capture frame for capturing and releasing the boat, and the rope of the hydraulic winch passes through the anti-sway device and is connected to the capture frame.

[0011] As a further improvement of the present invention, it is characterized in that the anti-sway device is telescopically connected to the boom bracket through a telescopic arm, a telescopic driving device is connected between the telescopic arm and the boom bracket, and the telescopic driving device drives the telescopic arm to be telescopic relative to the boom bracket.

[0012] As a further improvement of the present invention, the amplitude variation drive device includes an amplitude variation cylinder body and an amplitude variation telescopic rod, the amplitude variation cylinder body is arranged on the rotating bracket, the extended end of the amplitude variation telescopic rod is connected to the boom bracket, and the amplitude variation telescopic rod is telescopic relative to the amplitude variation cylinder body to realize the rotation of the boom bracket relative to the rotating bracket; the telescopic drive device includes a telescopic cylinder body and a telescopic rod, the telescopic cylinder body is arranged on the boom bracket, the extended end of the telescopic rod is connected to the capture frame, and the telescopic rod is telescopic relative to the telescopic cylinder body to realize the telescopic of the anti-sway device relative to the boom bracket.

[0013] As a further improvement of the present invention, the hydraulic winch is arranged on the telescopic arm or the boom bracket.

[0014] As a further improvement of the present invention, the travel drive device includes a hydraulic motor, a reduction gear box and a travel shaft connected in sequence, and the travel shaft rotates to enable the travel structure to move along the track bracket.

[0015] As a further improvement of the present invention, a rack is provided on the track bracket, a gear matching the rack is provided on the travel shaft, and the gear rolls along the rack to realize the movement of the travel structure on the track bracket.

[0016] As a further improvement of the present invention, the retractable system of the present invention further includes a power system and a control system, wherein the control system realizes electrical control of the retractable system, and the power system provides hydraulic drive for the retractable system.

[0017] Beneficial effects:

[0018] By installing the retractable system on the mother ship and moving it in a track-based manner, it effectively utilizes the space that is usually idle or difficult to fully utilize. This method is particularly suitable for ships with complex internal structures that cannot be easily modified on a large scale.

[0019] The rotating connection between the walking structure and the boom bracket and the variable amplitude function of the boom bracket itself enable the capture structure to achieve a wide range of working ranges, and accurately locate the boat to be launched and retrieved in both horizontal and vertical directions. This flexibility greatly improves the system's ability to support unmanned boats of different sizes and weight levels.

[0020] The design of the rotating structure not only allows the boom bracket to rotate relative to the walking bracket, but also enables the boat to enter and exit on both sides of the track bracket. This design greatly expands the operating range and flexibility of the system, allowing the unmanned boat to be quickly and safely deployed from different sides of the mother ship to adapt to different operating environments and mission requirements. With the support of the rotating structure, the system can arrange the unmanned boats under the track bracket. This can make full use of the deck space and efficiently store multiple unmanned boats even in a limited space. This not only improves storage efficiency, but also ensures the safety and stability of the unmanned boat, which is especially important in harsh sea conditions. Since the unmanned boats can be arranged directly under the track bracket, there is no need for complicated handling processes or additional auxiliary equipment, which greatly simplifies the deployment and retrieval process of the unmanned boat. This feature is of great significance in improving operational efficiency, reducing manpower requirements and reducing operational risks.

[0021] The anti-sway device equipped in the capture structure reduces the swaying of the boat caused by changing sea conditions, thereby reducing the risk during the retrieval and release process. In addition, the stable pulling force provided by the hydraulic winch further ensures the safety and reliability of the entire operation process.

[0022] With the help of efficient drive mechanisms (such as travel drive devices and rotation drive devices) and precise control systems, this system can complete multiple launch and recovery actions of small boats in a short period of time, greatly improving the efficiency of cluster deployment of unmanned boats. Through optimized spatial layout and multi-faceted operation capabilities, the system supports more efficient cluster deployment of unmanned boats, and can complete multiple launch and retraction operations in a short period of time, thereby enhancing the overall mission execution capability and response speed.

[0023] Due to its compact and adjustable structure, the present invention is applicable to various types of ships, including but not limited to research ships, patrol boats and even some military ships, and can achieve functional expansion without making major changes to the original hull. Compared with the traditional approach of requiring a comprehensive transformation of the entire ship to meet the requirements of unmanned boat clustering, this solution only requires the addition of a set of special equipment on the cabin roof, which greatly saves initial investment while retaining the possibility of future technology upgrades.

[0024] In summary, the system of the present invention solves the problems of space limitation, structural modification difficulties and low operating efficiency existing in existing mother ships when supporting unmanned boat cluster operations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] In order to better understand the purpose, structure and function of the present invention, a cabin top translation type integrated boat storage and launching system of the present invention is further described in detail below with reference to the accompanying drawings.

[0033] Implementation example:

[0034] like Figure 1As shown, a cabin top translation type integrated boat launching and retracting system includes a track bracket 100 fixed on the mother ship deck, and the openings on both sides of the track bracket 100 face the openings of the mother ship side wall or the outer bulwark of the open deck. The boat 800 is captured from the water surface and placed under the track bracket 100, and arranged in a concentrated manner along the ship width direction, or the boat 800 under the track bracket 100 is released to the water surface. The track bracket 100 is a track for the walking structure 200 to walk horizontally along the deck. The walking structure 200 moves between the mother ship and the water surface along the track bracket, and is connected to the capture structure 500 through the boom bracket 300. The capture structure 500 captures or releases the boat 800 at a designated position under the adjustment of the boom bracket 300, reasonably uses the area on the hull deck or the cabin space, performs integrated arrangement, and is released and recovered through the side of the mother ship. The walking structure 200 is also provided with a control system 700 for realizing the electrical control of the launching and retracting system, and a power system 600 for providing hydraulic drive for the launching and retracting system. The mother ship provides an electric power input to the launching and retracting system. The cable is connected to the electrical control box of the control system 700, and is connected to the pump station motor of the power system 600 through the control circuit. The operation of the motor causes the system hydraulic power system to start to build pressure, providing power guarantee for the subsequent hydraulic actuator action.

[0035] like Figure 2 and 3 As shown, the walking structure 200 includes a walking drive device 220 arranged on a walking bracket 210, and the walking drive device 220 includes a hydraulic motor 221, a reduction gear box 222 and a walking shaft 223 connected in sequence. In this embodiment, a gear is arranged on the walking shaft 223, and a rack is embedded in the upper end of the track bracket 100. The gear rolls on the rack to realize that the walking drive device 220 drives the walking bracket 210 to move along the track bracket 100.

[0036] The lower end of the traveling support 210 is connected to a rotary drive device 410, which includes a rotary motor and a rotary reducer. The rotary motor is the power source of the rotary action, and the torque is amplified by the rotary reducer. The output acts on the rotary support 420, so that the boom support 300 connected to the rotary support 420 rotates relative to the traveling support 210. The rotating structure 400 supports the boom support 300 to rotate in multiple directions, so that the unmanned boat can be quickly and safely retracted and released from both sides or below the track.

[0037] The boom support 300 is a frame with one end bent and the other end extending outward, and the connecting part is rotatably connected to the rotating support 420. The bent end is connected to the rotating support 420 through the amplitude change driving device 310, and the extending end is connected to the capture structure 500. Figure 5As shown, in this embodiment, the luffing drive device 310 is a hydraulic cylinder structure, the luffing cylinder 311 is fixed on the rotating bracket 420, the protruding end of the luffing telescopic rod 312 is connected to the boom bracket 300, and the luffing telescopic rod 312 is telescoped in the luffing cylinder 311 to realize the rotation of the boom bracket 300, change the initial lifting height and move the capture structure 500 up and down, lift the boat in the cabin and then transport it, and appropriately lower the distance from the boat to the water surface outside the cabin, so that the anti-sway device 550 is in continuous contact with the equipment to reduce the risk of shaking.

[0038] The capture structure 500 is connected to the boom support 300 through a telescopic arm 540. One end of the telescopic arm 540 is disposed inside the boom support 300, and the other end extends outward from the boom support 300. The extended end is connected to the anti-sway device 530. Figure 4 As shown, in this embodiment, the telescopic drive device 550 is a hydraulic cylinder structure, the telescopic cylinder 551 is fixed on the boom support 300, the extended end of the telescopic rod 552 is connected to the telescopic arm 540, and the telescopic rod 552 is telescoped in the telescopic cylinder 551 to achieve the telescopic arm 540 relative to the boom support 300. The telescopic arm 540 extends outward, which can increase the span, further reduce the height of the suspension point from the water surface, and improve the safety of the retracting and releasing process; the telescopic arm 540 retracts, which can reduce the equipment storage space and improve the adaptability of the steering in the cabin. The hydraulic winch 510 is set on the upper end surface of the telescopic arm 540 located in the boom support 300, and releases the rope to the capture frame 520. The rope passes through the anti-sway device 530 and is connected to the capture frame 520. The forward and reverse rotation of the hydraulic winch 510 drives the release and recovery of the rope on the winch, that is, the lifting and lowering of the capture frame 520 connected thereto. The capture frame 520 is a hollow frame that can be opened and closed when capturing and releasing the boat 800, and can clamp and protect the boat 800 during transportation. The anti-sway device 530 and the hydraulic winch 510 ensure stability and safety during the retrieval and release process. The interface form of the anti-sway joint adopts a simple box-shaped structure, which is convenient for docking different capture frames 520 to meet the ability to release and recover different captured objects.

[0039] like Figure 6As shown, when the folding and launching system performs the boat launching action, the walking structure 200 moves on the track bracket 100 to the boat storage position, drives the variable amplitude driving device 310 to make the capture frame 520 descend to the boat capture position, and is firmly connected to the boat 800; then the variable amplitude telescopic rod 312 is driven to retract, the capture frame 520 rises, and the boat 800 is lifted off the deck storage bracket; the walking structure 200 moves on the track bracket 100 to move the boat to the side release position, drives the telescopic arm 540 to extend, increases the span, and the hydraulic winch 510 rotates to release the capture frame 520 to the specified water surface, and the capture frame 520 opens to complete the release of the boat 800. The recovery process is opposite to the release process. When the boats 800 need to be folded and launched in sequence, the rotating structure 400 drives the adjustment of the position of the capture frame 520 by rotating the boom bracket 300, so that the boats 800 can be placed in sequence, and the folding and launching of the boats 800 from both sides of the side in different directions can also be realized.

[0040] The launching and retracting system of the present invention effectively utilizes the space on the ship that is usually difficult to fully utilize by installing a track translation system on the open deck or built-in cabin of a non-dock type vessel; it realizes the integrated arrangement and side launching and retracting of multiple boats and ships, has good loading adaptability, can be carried on the flat deck or cabin of the mother ship, and can be adapted to a variety of small boats or vehicles; it is suitable for various types of ships and can achieve functional expansion without major modifications to the original hull; compared with comprehensive modifications to the entire hull, the system only needs to add special equipment, which reduces the initial investment cost and is convenient for future upgrades and maintenance.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
