Description

Technical Field

[0001] The present invention relates to the technical field of ships, and particularly to a boat retracting and deploying device and a ship. Background Art

[0002] The stern chute type retracting and deploying technology realizes the retracting and deploying operations of surface boats or underwater unmanned vehicles through a chute system. Usually, during recovery, the surface boat selects an appropriate ramming and draining timing and rams into the stern chute at a speed higher than that of the mother ship. The arresting cable in front of the chute automatically hooks up with the bow hooking mechanism of the boat, and the arresting and buffering mechanism absorbs the kinetic energy when the surface boat rams and drains, so that it is blocked and stopped within a short distance, thus realizing the recovery of the surface boat. During deployment, the electric control mechanism of the surface boat automatically opens the hook. At this time, the bow of the boat is separated from the arresting cable, and the surface boat slides down to the water surface by its own weight. If the external wind and waves are relatively large, at this time, a blocking and tensioning device needs to be used to push the surface boat to a position closer to the water surface, and then it slides down freely.

[0003] However, the chute system of the above-mentioned retracting and deploying form is a fixed facility on the ship, lacking the characteristics of quick disassembly and assembly, and not having the function of modular flexible loading. In addition, the positioning and installation of the guiding mechanism, rollers, etc. need to rely on the hull structure, which usually results in the relative position of this type of device and the hull being fixed, unable to adjust its own posture and angle, inconvenient for the stored boat after recovery to be stored horizontally, and can only be placed obliquely on the chute, which is not conducive to the preservation of the boat and will also compress the space of other cabins of the ship. Summary of the Invention

[0041] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

[0042] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely means that the horizontal height of the first feature is lower than that of the second feature.

[0044] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0045] The present invention discloses a boat retracting and deploying device, such as Figure 1As shown in the figure, the boat retracting and deploying device includes a mounting frame 1, a flipping frame 2, a sliding frame 3, a capturing mechanism 4, a flipping driving mechanism 5, and a telescopic driving mechanism 6. Among them, the mounting frame 1 is detachably connected to an external mounting platform 100; the flipping frame 2 is arranged on the mounting frame 1 and is movably connected to the mounting frame 1; the sliding frame 3 is arranged on the flipping frame 2 and is slidably connected to the flipping frame 2; the capturing mechanism 4 is slidably arranged on the sliding frame 3 and is used for capturing a boat docked with the boat retracting and deploying device; the flipping driving mechanism 5 is used for driving the flipping frame 2 to flip, and the telescopic driving mechanism 6 is used for driving the sliding frame 3 to act. It can be understood that the boat retracting and deploying device of the present invention has comprehensive functions and adopts a modular design. By detachably connecting the mounting frame 1 to the mounting platform 100, and the remaining structures are all arranged based on the mounting frame 1 as the installation foundation, it can realize the rapid disassembly and assembly of its own structure. The capturing mechanism 4 can capture and connect with the boat. Combined with the settings of the flipping frame 2 and the sliding frame 3, it can adjust the position and attitude of the boat under the action of the flipping driving mechanism 5 and the telescopic driving mechanism 6, thus facilitating the storage and release of the boat.

[0046] In some embodiments, as Figure 1 and Figure 2 shown, the mounting frame 1 includes two first connectors 11 and at least two second connectors 12. The second connectors 12 are fixedly arranged between the two first connectors 11. The first connectors 11 are used for fitting with the mounting platform 100 and being detachably connected to the mounting platform 100. Specifically, the first connectors 11 are generally L-shaped, that is, the two ends of the first connectors 11 are angled, so as to fit with the slope surface of the mounting platform 100. The two first connectors 11 are arranged at intervals in parallel. A number of second connectors 12 are arranged between the two first connectors 11. The two ends of the second connectors 12 are respectively fixedly connected to the two first connectors 11 to fix and support the first connectors 11. Among them, the extending directions of the first connectors 11 and the second connectors 12 are perpendicular to each other, and both the first connectors 11 and the second connectors 12 are detachably connected to the mounting platform 100. In some embodiments, the angles at both ends of the first connectors 11 are adjustable to adapt to different types of slope surfaces. It can be understood that by detachably connecting the mounting frame 1 to the mounting platform 100, for example, directly using bolts for fixation, the structural settings on the mounting platform 100 can be minimized to the greatest extent. The settings of the first connectors 11 and the second connectors 12 can ensure the structural strength of the mounting frame 1. Other structures are all based on the mounting frame 1 as the installation foundation, while realizing the modular design, ensuring the stability of the device structure and function.

[0047] In some embodiments, as Figure 1As shown in the figure, both the flipping frame 2 and the sliding frame 3 include: a main frame body and cross beams. There are two main frame bodies, and the two main frame bodies are arranged in parallel; there are multiple cross beams, and the multiple cross beams are arranged at intervals between the two main frame bodies; among them, the main frame body of the sliding frame 3 is slidably connected to the main frame body of the flipping frame 2. In some specific embodiments, the main frame body is in a U-shaped. The cross beams of the flipping frame 2 are arranged below the main frame body to avoid interference with the main frame body of the sliding frame 3. It can be understood that the main frame body can be an integrally formed part or can be formed by welding multiple identical structural parts. The size of the main frame body of the sliding frame 3 is slightly smaller than the size of the main frame body of the flipping frame 2, so that the main frame body of the sliding frame 3 can be embedded inside the main frame body of the flipping frame 2, enabling the main frame body of the sliding frame 3 to slide relative to the main frame body of the flipping frame 2.

[0048] In some embodiments, such as Figure 6 and Figure 7 As shown in the figure, the capture mechanism 4 includes a capture gantry 41, a capture bracket 42 and a locking assembly 43. Among them, the capture gantry 41 is slidably arranged on the sliding frame 3; the capture bracket 42 is fixedly arranged on the capture gantry 41, the capture bracket 42 is in a dovetail shape, and a capture groove 421 is arranged on the capture bracket 42 for limiting the tow hook 200 of the boat; the locking assembly 43 is arranged on the capture bracket 42 for locking or releasing the tow hook 200. It can be understood that, as Figure 8 and Figure 9 shown in the figure, the dovetail-shaped capture bracket 42 is in an inverted V shape. When docking with the boat, it can guide the tow hook 200 on the boat to enter the capture groove 421 at the top of the center of the dovetail shape more smoothly and lock the tow hook 200 through the locking assembly 43.

[0049] In some embodiments, such as Figures 7 - 9As shown, the locking assembly 43 includes a hook 431, a limit hook 432 and a reset member 433. The hook 431 is rotatably arranged on the capture bracket 42 and can cooperate with the capture groove 421 on the capture bracket 42 to lock the tow hook 200; the limit hook 432 is rotatably arranged on the capture bracket 42 and is located on the opposite side of the hook 431, and can limit the rotation of the hook 431; there are two reset members 433. One end of the reset member 433 is connected to the hook 431 or the limit hook 432, and the other end is connected to the capture bracket 42, so that the initial position of the opening of the hook groove of the hook 431 is consistent with the opening direction of the capture groove 421, and the hook claw of the limit hook 432 has a tendency to rotate towards the hook 431. It can be understood that the tow hook 200 on the boat can be limited and locked by the cooperation of the hook 431 and the capture groove 421, so as to achieve capture docking. Through the setting of the reset member 433, the initial position of the opening of the hook 431 is consistent with the opening position of the capture groove 421. The limit hook 432 is rotatably arranged on the capture bracket 42. Under the action of the reset member 433, the hook claw of the limit hook 432 has a tendency to rotate towards the hook 431. The tow hook 200 enters the capture groove 421 and presses against the hook 431 to rotate, realizing the limitation of the tow hook 200. Under the action of the reset member 433, the limit hook 432 continues to rotate towards the hook 431, preventing the hook 431 from reversing. The hook claws on the hook 431 and the limit hook 432 are similar to ratchet structures and can only rotate in one direction without external force. When it is necessary to release the hook, the limit hook 432 can be manually operated to release the hook 431, so that the hook 431 can rotate in the reverse direction to release the tow hook 200. The reset member 433 is an elastic member, such as a spring.

[0050] In some embodiments, as Figures 7 - 9 shown, the locking assembly 43 further includes an unlocking member 434. The unlocking member 434 is arranged on the capture bracket 42, and its output end is connected to the limit hook 432. It can be understood that due to the position of the capture bracket 42, there is a certain risk in manually operating the limit hook 432 to release the hook 431. Therefore, the unlocking member 434 is provided to achieve unlocking, so that the personnel can remotely control whether to unlock. The unlocking member 434 is a telescopic member, such as a telescopic oil cylinder. Of course, the unlocking member 434 can also be a rotating member, and a transmission structure is set to drive the limit hook 432.

[0051] In some embodiments, as Figure 2 and Figure 3As shown, the flipping drive mechanism 5 includes a flipping member 51 and a first drive member 52. Two ends of the flipping member 51 are respectively rotatably connected to the mounting frame 1 and the flipping frame 2. One end of the drive member is disposed on the mounting frame 1, and the other end is connected to the flipping frame 2. Specifically, there are four flipping members 51, symmetrically arranged on both sides of the flipping frame 2 and the mounting frame 1, and there are two drive members to drive the flipping frame 2 to flip relative to the mounting frame 1, so as to realize the adjustment of the angle and position attitude of the flipping frame 2. It can be understood that the flipping movement of the flipping frame 2 includes both the change of its own angle relative to the mounting frame 1 and the movement of its position. The first drive member 52 can be a hydraulic cylinder with telescopic ability.

[0052] In some embodiments, as Figures 1 - 3 shown, the telescopic drive mechanism 6 includes a second drive member 62. The second drive member 62 is disposed on the flipping frame 2, and the output end of the second drive member 62 is connected to the sliding frame 3. It can be understood that the second drive member 62 can be set as a telescopic oil cylinder, and the telescopic end of the telescopic oil cylinder is connected to the sliding frame 3 to push the sliding frame 3 out of the flipping frame 2 or retract the sliding frame 3 from the outside into the flipping frame 2.

[0053] In some embodiments, as Figure 4 and Figure 5 shown, the capturing mechanism 4 further includes a transmission member 44. One end of the transmission member 44 is connected to the flipping frame 2, and the other end is connected to the capturing gantry 41. Specifically, the transmission member 44 is set as a steel cable. The steel cable is wound around the sliding frame 3. Two ends of the sliding frame 3 are provided with rollers 31 to reduce the friction between the steel cable and the sliding frame 3. Two ends of the steel cable are respectively fixedly connected to two ends of the moving direction of the capturing gantry 41, and the middle section is fixedly connected to the flipping frame 2. When the telescopic oil cylinder pushes out the sliding frame 3, the flipping frame 2 also moves relative to the sliding frame 3, thereby pulling the steel cable to rotate around the sliding frame 3, pulling the capturing gantry 41 to the end of the sliding frame 3 close to the boat for capturing and docking. When the sliding frame 3 is retracted, the flipping frame 2 pulls the steel cable to reverse and pulls back the capturing gantry 41. In other embodiments, there are two steel cables, and the two steel cables form a closed loop and are wound around the sliding frame 3. One ends of the two steel cables are fixedly connected to the flipping frame 2, and the other ends are respectively fixedly connected to two ends of the moving direction of the capturing gantry 41. Optionally, there are two groups of transmission members 44, and one group is respectively arranged on both sides of the sliding frame 3 to make the transmission more stable.

[0054] In some embodiments, as Figure 1 and Figure 2As shown in the figure, the boat retracting and deploying device of the present invention further includes a guiding upright column 7 and an adjustable support 8. The guiding upright column 7 is arranged at one end of the sliding frame 3 away from the flipping frame 2; the adjustable support 8 is arranged on the cross beam of the sliding frame 3 and is symmetrically arranged along the midline of the cross beam of the sliding frame 3. It can be understood that the guiding upright column 7 is used to laterally limit the boat when the gantry 41 drags the boat upward, and the adjustable support 8 provides a fixed support for the storage of the boat. The distance and height between the adjustable supports 8 are adjustable to adapt to the bottom line shapes of various boats. In some specific embodiments, guiding wheels are arranged on the guiding upright column 7 to prevent the guiding upright column 7 from directly guiding the boat in the form of collision and friction and scratching the boat. In some embodiments, a single adjustable support 8 extends along the length direction of the sliding frame 3, straddles multiple cross beams, and is detachably connected to the cross beams. The two adjustable supports 8 are symmetrically arranged along the midline of the cross beam of the sliding frame 3. A plurality of first mounting holes 32 are arranged on the cross beam of the sliding frame 3 along the extending direction of the cross beam. Second mounting holes 81 are arranged on the adjustable support 8. There are at least two groups of the second mounting holes 81, and each group of the second mounting holes 81 is arranged at intervals in the vertical direction. The number of the second mounting holes 81 in each group is less than the number of the first mounting holes 32, so that the positions of the adjustable support 8 in the horizontal and vertical directions can be adjusted. In other embodiments, the adjustable support 8 can also be in other forms. For example, there are multiple groups of adjustable supports 8, and one group of adjustable supports 8 is arranged on each cross beam of the sliding frame 3. Each group of adjustable supports 8 has two, and the two adjustable supports 8 are symmetrically arranged along the midline of the cross beam of the sliding frame 3.

[0055] The boat retracting and deploying device of the present invention further includes a hydraulic pump station 10 and an electric control box 9. As Figure 1 shown, both the hydraulic pump station 10 and the electric control box 9 are arranged on the mounting frame 1. Electrical components are installed inside the electric control box 9 for collecting sensor signals and outputting operation commands; the hydraulic pump station 10 can provide pressure oil for the actions of driving components such as the flipping driving mechanism 5, the telescopic driving mechanism 6, and the unlocking member 434. It can be understood that the operator can hold a remote control or use a superior control system to remotely control the boat retracting and deploying device, making it have a high level of automation.

[0056] The ship disclosed by the present invention can adjust the position and attitude of the boat, facilitating the storage and release of the boat. The ship includes a mounting platform 100. The mounting platform 100 is arranged on the working deck of the ship or in the dock cabin. The ship further includes the boat retracting and deploying device as described above.

[0057] The preparations before the boat retracting and deploying device and the ship perform the deployment and recovery operations are as follows:

[0058] Adjust the adjustable support 8 to the height and width dimensions suitable for the target boat. Adjust the boat retracting and deploying device to the recovery preparation state. Specifically: As Figure 1 and Figure 2As shown, the first driving member 52 is extended to push the flip frame 2 to flip downward to the extreme position. At this time, the supporting point on the flip frame 2 contacts the slope and has a good impact resistance; the second driving member 62 is extended to push the sliding frame 3 to slide inside the flip frame 2 and extend to the water surface; the capture door frame 41 is extended to the water surface along with the sliding frame 3 under the action of the steel cable, and the capture door frame 41 slides inside the sliding frame 3 and moves to the water surface; the second driving member 62 is controlled to extend until the capture door frame 41 reaches a state where it can capture the boat. The structure of the capture bracket 42 is shown in FIG. Figure 2 As shown, the dovetail shape is provided to form a guide groove, which facilitates the optical axis of the towing hook 200 to hit the hook 431 to achieve the capture of the boat.

[0059] like Figure 7 In the state shown, the locking assembly 43 is prepared for the impact of the towing hook 200: at this time, the hook 431 is in an open state under the action of the reset member 433, the limit hook 432 is in a closed state under the action of the reset member 433, and the unlocking member 434 is in a retracted state.

[0060] The boat launching and retrieving device and the ship recovery operation process are as follows:

[0061] The boat is controlled to move forward toward the capture gantry 41 at a lower speed, and the optical axis of the towing hook 200 is driven into the dovetail side of the capture bracket 42. When the optical axis of the towing hook 200 contacts the hook 431, the compressed hook 431 rotates into the capture groove 421. When the sharp corner of the installation hook 431 passes over the claw on the limit hook 432, the claw on the limit hook 432 limits the reverse rotation of the hook 431, which can limit the towing hook 200 from coming out and realize the capture of the boat. At this time, the state of the locking component 43 is as follows: Figure 8 and Figure 9 shown.

[0062] Then the second driving member 62 is retracted, driving the sliding frame 3 to slide in the flip frame 2 and retract into the flip frame 2; the capturing door frame 41 is retracted together with the sliding frame 3 under the combined traction of the steel cables at both ends, and the capturing door frame 41 slides in the sliding frame 3 and moves onto the deck, thereby driving the boat to slide on the adjustable support 8 toward the mounting platform 100. During this process, the guide column 7 will limit the lateral movement of the boat to prevent the boat from tipping over until the second driving member 62 is completely retracted.

[0063] Retract the first driving member 52, pull the flip frame 2 to flip upward to the limit position, at this time, the support point on the flip frame 2 is in contact with the support point of the mounting frame 1, and has a good bearing capacity, such as Figure 3 As shown, finally the boat and the ship deck surface fastening points are tied together to achieve rapid recovery and horizontal storage of the boat.

[0064] The boat launching and retracting device and the ship deploying operation process are as follows:

[0065] First, release the lashing of the boat and the fastening points on the deck surface. Control the extension of the first driving member 52 to push the turning frame 2 to turn downward to the limit position. At this time, the support point on the turning frame 2 contacts the slope surface of the installation platform 100.

[0066] Manually toggle the limit hook 432 or remotely control the unlocking member 434 to extend the piston rod to release the hook 431. As Figure 8 shown, the boat slides towards the water surface under the action of the component of gravity and falls into the water, realizing the rapid release of the boat. The boat retracting and deploying device disclosed in the present invention has comprehensive functions and a modular design. It is detachably connected to the installation platform through the mounting frame, and the rest of the structures are arranged based on the mounting frame as the installation foundation, enabling the rapid disassembly and assembly of its own structure. The capture mechanism can be connected to the captured boat, and the turning frame and the sliding frame can adjust the position and attitude of the boat under the action of the turning drive mechanism and the telescopic drive mechanism, facilitating the storage and release of the boat.

[0067] The ship disclosed in the present invention realizes the simplification of the hull structure, increases the available area on the ship, and at the same time can adjust the position and attitude of the boat, facilitating the storage and release of the boat by modularly installing the boat retracting and deploying device on the installation platform.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention.
