Description

Technical Field

[0001] This invention belongs to the field of ship mooring technology, and specifically relates to a ship mooring device. Background Technology

[0002] In the field of ship operations, mooring systems are key equipment for ensuring the safe berthing of ships, and their performance and reliability directly affect the stability and safety of ships in berthing scenarios such as docks and anchorages. With the continuous growth of global trade, the trend of larger and more specialized ships is becoming increasingly apparent, and the requirements for port operation efficiency are constantly increasing, which places more stringent demands on mooring systems.

[0003] Traditionally, mooring systems primarily consist of a combination of mooring lines and mooring bollards. The mooring lines, by their own strength, connect the vessel to shore-based facilities, while the mooring bollards provide a stable anchor point for the lines. This basic configuration, to a certain extent, meets the basic berthing needs of vessels, ensuring they remain relatively stationary in normal sea conditions, preventing drift, guaranteeing safe berthing, and maintaining a safe distance from the dock or other vessels. It plays an indispensable role in routine berthing and cargo loading / unloading operations.

[0004] When a ship is anchored at sea, it is affected by various marine factors such as wind, waves, and tides, causing it to sway. The dynamic tension generated by the swaying is transmitted directly to the winch along the cable. When the tension is large, the shaft of the undock will be subjected to a torque that exceeds its bearing capacity, causing the shaft to bend and deform, affecting the normal rotation of the undock and the cable winding and unwinding function.

[0005] Therefore, the present invention provides a ship mooring device. Summary of the Invention

[0011] Preferably, the tension self-adjusting assembly further includes a U-shaped platform, which is fixedly connected to one side of the connecting column. Multiple insertion rods are evenly arranged and inserted into the inner wall of the U-shaped platform. Each insertion rod is fixedly connected to a clamping seat. The shafts of the multiple clamping seats are fixedly connected to the inner wall of the guide wheel. A buffer spring is fixedly connected between the bottom of each clamping seat and the top of the U-shaped platform. Multiple clamping components are fixedly connected to the top of the U-shaped platform. Fixed pulleys are fixedly connected to the outer wall of the shafts of the clamping components. The cable is wound around the outer wall of the multiple fixed pulleys.

[0012] Preferably, the surface of the guide wheel is provided with grooves, and a number of balls are fixedly connected to the inner wall of the grooves.

[0013] Preferably, each plug rod has a bottom block fixedly connected to its bottom, a support frame is provided below each bottom block, and a moving block is fixedly connected to the bottom of each support frame.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The ship mooring device of the present invention, through the guide assembly, ensures that the lower and upper clamps of the guide assembly provide stable guidance for the cable during the cable release and retrieval process, ensuring that the cable maintains a smooth direction during the release process and avoiding twisting, jamming, or other issues. The guide assembly has flexible adjustment capabilities and can make adaptive adjustments according to the real-time direction of the cable on the outer wall of the winch, ensuring the smoothness of the release process and also ensuring the neat winding of the cable during the retrieval process, avoiding uneven phenomena such as cable accumulation and crossing.

[0019] 2. The ship mooring device of the present invention uses a tension self-adjusting component. The cable is continuously wound around multiple guide wheels of the tension self-adjusting component. When the ship is swayed by ocean factors, the dynamic tension generated will be transmitted to the cable. When the ship sways and the cable tension increases, the tension self-adjusting component starts to function, which can absorb and consume the energy generated by the ship swaying, thereby buffering the change in tension on the cable.

[0020] 3. The ship mooring device of the present invention involves multiple guide wheels participating in the tension adjustment process in sequence. This tiered release mechanism can gradually and orderly release the adjustment capacity of the guide wheels according to the degree of ship swaying and the change in the tension of the cable, avoiding the instability that may be caused by the simultaneous action of all guide wheels. At the same time, it also improves the flexibility and adaptability of the tension self-adjusting component, and can better cope with the influence of ship swaying on cable tension under different working conditions, ensuring that the mooring device always maintains a stable and reliable working state.

[0021] 4. In the ship mooring device described in this invention, when the last set of guide wheels is about to descend to the lowest point, it means that the tension adjustment of the tension self-adjusting component is about to reach its limit. When the last set of bottom contact blocks is about to descend to the lowest point, it will trigger the warning component located below it. Once the warning component is triggered, it will immediately send a signal to the warning light, causing the warning light to emit a clear warning light, promptly alerting the staff that the current tension self-adjusting component is approaching its working limit and that they need to closely monitor the condition of the mooring ropes and the mooring status of the ship in order to take appropriate measures to avoid potential dangers and ensure the safety of the mooring device and the ship.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1 to 8 As shown, the present invention provides a technical solution: a ship mooring device, including a bearing seat 1, a winch 2 fixedly connected to the outer wall of the shaft of the bearing seat 1, a cable 3 uniformly wound on the outer wall of the winch 2, a servo motor 5 fixedly connected to one side of the winch 2, a gear disk 6 fixedly connected to the output shaft of the servo motor 5, a gear disk 7 fixedly connected to one end of the shaft of the bearing seat 1, the teeth of the gear disk 6 and the gear disk 7 meshing with each other, a guide assembly provided on one side of the bearing seat 1, the guide assembly including a lower clamping plate 9 and an upper clamping plate 10, the guide assembly guiding the cable 3 during the release and reeling process, a tension self-adjusting assembly provided on the side of the guide assembly, the tension self-adjusting assembly including multiple guide wheels 23 arranged side by side, the outer wall of the cable 3 continuously wound with the multiple guide wheels 23.

[0034] During operation: In the initial state, the cable 3 has passed through the guide assembly and the tension self-adjusting assembly. When it is necessary to connect the connecting end of the cable 3 to the ship, the servo motor 5 is started. Its output shaft drives the gear disk 7 to rotate through the gear disk 1 6. The gear disk 7 drives the winch 2 to rotate, which releases the cable 3 wound on the surface of the winch 2, thereby changing the length of the cable 3. The operator can pull the connecting end of the cable 3 to connect it to the ship.

[0035] During the process of workers pulling the connection end of the cable 3 to connect with the ship, the lower clamp 9 and upper clamp 10 of the guide assembly always provide stable guidance for the cable 3, ensuring that the cable 3 maintains a smooth direction during the release process and avoiding twisting, jamming, or other issues. Because the winding position of the cable 3 on the outer wall of the winch 2 changes constantly during the release and reeling processes; specifically, during release, the cable 3 gradually unwinds from the winch 2, with the winding point moving along the outer wall of the winch 2; during reeling, the cable 3 rewinds onto the winch 2, and the winding position also changes continuously. The guide assembly has flexible adjustment capabilities and can make adaptive adjustments according to the real-time direction of the cable 3 on the outer wall of the winch 2. This not only ensures the smoothness of the release process but also guarantees the neat winding of the cable during the reeling process, avoiding uneven phenomena such as cable accumulation and crossing.

[0036] The cable 3 is continuously wound around multiple guide wheels 23 of the tension self-adjusting assembly. When the ship is anchored on the sea, it is constantly swaying to varying degrees due to the combined effects of various marine factors such as wind, waves, and tides. After the line release operation is completed and the cable 3 is connected to the ship, the winch 2 is stationary and no longer actively retracts or releases. However, the dynamic tension generated by the ship's swaying is directly transmitted to the winch 2 along the cable 3. When the tension caused by the ship's swaying is large, the shaft of the winch 2 is subjected to a torque exceeding its bearing capacity, causing the shaft to bend and deform, affecting the normal rotation of the winch 2 and the retraction and release function of the cable 3. However, through the tension self-adjusting assembly, when the ship's swaying causes the tension of the cable 3 to increase, the tension self-adjusting assembly begins to function, absorbing and dissipating the energy generated by the ship's swaying, thereby buffering the change in tension on the cable 3.

[0037] Through the above embodiments, the guide assembly ensures that the lower clamp 9 and upper clamp 10 of the guide assembly provide stable guidance for the cable 3 during the laying and winding processes, ensuring that the cable 3 maintains a smooth direction during laying and avoiding twisting, jamming, or other issues. The guide assembly has flexible adjustment capabilities and can make adaptive adjustments based on the real-time direction of the cable 3 on the outer wall of the winch 2, ensuring the smoothness of the laying process and the neat winding of the cable during winding, avoiding uneven phenomena such as cable 3 accumulation or crossing. Through the tension self-adjusting assembly, the cable 3 is continuously wound around multiple guide wheels 23 of the tension self-adjusting assembly. When the ship is swayed by ocean factors, the resulting dynamic tension is transmitted to the cable 3. When the ship's swaying causes the tension of the cable 3 to increase, the tension self-adjusting assembly begins to function, absorbing and dissipating the energy generated by the ship's swaying, thereby buffering the changes in tension on the cable 3.

[0038] like Figures 3 to 4As shown, the guide assembly also includes a connecting platform 8, a lower clamping plate 9 fixedly connected to the side of the connecting platform 8, an upper clamping plate 10 slidably connected to the side of the connecting platform 8, a top plate 13 fixedly connected to the top of the upper clamping plate 10 via a round rod, a drive motor 15 fixedly installed on the top of the connecting platform 8, and an extrusion wheel 14 fixedly connected to the output shaft of the drive motor 15, with the outer wall of the extrusion wheel 14 fitting against the top of the top plate 13.

[0039] During operation: During the cable laying process, the upper clamping plate 10 is positioned away from the lower clamping plate 9. At this time, the outer wall of the cable 3 only contacts the inner groove of the lower clamping plate 9. The smooth surface of the inner groove of the lower clamping plate 9 and its design to fit the shape of the cable 3 result in minimal friction and resistance experienced by the cable 3 when passing through the guide assembly, allowing it to be smoothly released from the winch 2. During mooring, the drive motor 15 is started, and the output shaft of the drive motor 15 begins to rotate, thereby driving the compression wheel 14 to rotate. Since the outer wall of the compression wheel 14 is in contact with the top of the top plate 13, during rotation, the compression wheel 14... 4 will exert a downward compressive force on the top plate 13. The top plate 13 will drive the upper clamping plate 10 to move downward along the side of the connecting platform 8, so that the upper clamping plate 10 gradually approaches the lower clamping plate 9. As the distance between the upper clamping plate 10 and the lower clamping plate 9 continues to decrease, the cable 3 located in the middle will eventually be compressed. The compression of the cable 3 by the upper clamping plate 10 and the lower clamping plate 9 can significantly increase the friction between the cable 3 and the guide assembly. When the ship is rocking, the tension transmitted to the winch 2 is reduced, thereby reducing the impact of the ship's rocking on the device and playing a good protective role for the components of the device.

[0040] like Figures 3 to 4 As shown, a fixing rod 11 is symmetrically fixedly connected to the top of the lower clamping plate 9, the inner wall of the upper clamping plate 10 is slidably connected to the outer wall of the fixing rod 11, and a return spring 12 is fixedly connected to the top of the upper clamping plate 10. The end of the return spring 12 away from the upper clamping plate 10 is fixedly connected to the bottom of the connecting platform 8.

[0041] During operation: The fixed rod 11 and the return spring 12 provide precise guidance for the upper clamping plate 10 to move down and press the cable 3, ensuring that the upper clamping plate 10 can move stably and accurately to the appropriate position to effectively press the cable 3. When mooring is completed and the line needs to be retrieved, the drive motor 15 continues to start and drive the compression wheel 14 to rotate, so that it no longer applies pressure to the top plate 13. The return spring 12 will pull the upper clamping plate 10 and the top plate 13 to rise and reset. As the upper clamping plate 10 rises, the distance between it and the lower clamping plate 9 increases, and it no longer presses the cable 3. In this way, the restraint and resistance of the cable 3 during the retrieval process are greatly reduced, and it can be retrieved more smoothly, effectively ensuring the smoothness of the retrieval process and improving the working efficiency of the entire mooring device's retrieval link.

[0042] like Figure 3 and Figure 5As shown, a connecting column 21 is fixedly connected to the bottom of the connecting platform 8, and an internal threaded slider 16 is fixedly connected to the bottom of the connecting column 21. A limiting slide 17 is fixedly installed on the side of the bearing seat 1. The internal threaded slider 16 is slidably connected to the inner wall of the limiting slide 17. A threaded rod 18 is rotatably connected to the inner wall of the limiting slide 17. The inner wall of the internal threaded slider 16 is threadedly connected to the outer wall of the threaded rod 18. A transmission ring 19 is fixedly connected to the shaft end of the threaded rod 18 and the gear disc 6. A transmission belt 20 is connected between the outer walls of the two transmission rings 19. The pitch of the threaded rod 18 is the same as the diameter of the cable 3.

[0043] During operation: During the cable laying process, the threaded rod 18 can be rotated through the transmission relationship between the transmission ring 19 and the transmission belt 20. When the threaded rod 18 rotates, it drives the internal threaded slider 16 to slide along the inner wall of the limiting slide block 17. The internal threaded slider 16 can drive the entire guide assembly to move through the connecting column 21, so that the entire guide assembly matches the real-time position of the cable 3 during laying and winding, and always maintains a good guiding effect on the cable 3. Furthermore, the pitch of the threaded rod 18 is the same as the diameter of the cable 3, so that during the laying and winding of the cable 3, the rotation of the threaded rod 18 drives the internal threaded slider 16 to slide along the inner wall of the limiting slide block 17. The distance the threaded slider 16 moves precisely corresponds to the length of cable 3 being wound up or down. For example, when winding up the cable, the threaded rod 18 rotates at a certain angle, and the internal threaded slider 16 moves a distance of one thread pitch, which corresponds exactly to the amount of cable 3 being wound up by one cable diameter length, further ensuring that the cable 3 is wound up and down neatly and orderly. The guide component can move precisely according to the real-time position of the cable 3, ensuring that the cable 3 always travels along the correct path during the winding and unwinding process. While ensuring the smooth winding and unwinding of the cable, it can also make the cable 3 evenly and neatly wound on the cable winch 2, avoiding the occurrence of accumulation and crossing.

[0044] like Figures 5 to 7 As shown, the tension self-adjusting assembly also includes a U-shaped platform 22, which is fixedly connected to one side of the connecting column 21. Multiple insertion rods 25 are evenly arranged and inserted into the inner wall of the U-shaped platform 22. A clamping seat 24 is fixedly connected above each insertion rod 25. The shafts of the multiple clamping seats 24 are fixedly connected to the inner wall of the guide wheel 23. A buffer spring 26 is fixedly connected between the bottom of each clamping seat 24 and the top of the U-shaped platform 22. Multiple clamping members 30 are fixedly connected to the top of the U-shaped platform 22. Fixed pulleys 31 are fixedly connected to the outer wall of the shaft of each clamping member 30. The cable 3 is wound around the outer wall of the multiple fixed pulleys 31.

[0045] During operation: When the ship rocks, the foremost guide wheel 23 is the first to be subjected to the tension transmitted by the cable 3. Under this tension, the clamping seat 24 moves downward, simultaneously driving the plug rod 25 to move downward along the inner wall of the U-shaped platform 22. During this process, the clamping seat 24 compresses the buffer spring 26, causing the buffer spring 26 to deform. The elastic deformation of the buffer spring 26 can absorb and buffer part of the tension, playing a role in buffering and shock absorption, preventing damage to the equipment caused by excessive tension in an instant. As the guide wheel 23 moves downward, the connection length between the cable 3 and the ship increases (i.e., releasing part of the cable). This adaptive change can automatically adjust the effective length of the cable 3 according to the changes in tension caused by the ship's rocking, thereby adjusting the tension of the cable 3. When the tension decreases, the buffer spring 26 will restore its deformation, pushing the clamping seat 24 and the guide wheel 23 to move upward, tightening the cable 3, so that the cable 3 is always kept within a suitable tension range.

[0046] like Figure 7 As shown, the surface of the guide wheel 23 is provided with grooves 28, and a number of balls 29 are fixedly connected to the inner wall of the grooves 28.

[0047] During operation: The cable 3 comes into direct contact with the guide wheel 23 and generates relative motion during the winding and unwinding process. The presence of the ball bearing 29 transforms the original sliding friction between the cable 3 and the inner wall of the groove 28 of the guide wheel 23 into rolling friction, reducing surface damage caused by friction, extending the service life of the cable 3, and ensuring the strength and reliability of the cable 3.

[0048] like Figures 6 to 8 As shown, each of the plug-in rods 25 has a bottom block 27 fixedly connected to its bottom. Each bottom block 27 has a support frame 33 below it. Each support frame 33 has a moving block 34 fixedly connected to its bottom. Each threaded slider 16 has multiple inner groove seats 35 on one side. The threaded slider 16 is fixedly connected to one of the inner groove seats 35 via a connecting rod. The multiple inner groove seats 35 are fixedly connected together by a fixing plate. The moving blocks 34 are slidably connected to the inner walls of the multiple inner groove seats 35 respectively. A telescopic rod 36 is fixedly connected to one side of the inner groove seat 35 at the frontmost position. One end of the telescopic rod 36 is fixedly connected to the side of one of the moving blocks 34. Magnetic components are provided between the multiple bottom blocks 27 and the corresponding moving blocks 34, which can release the restriction on the next bottom block 27.

[0049] During operation: In the initial state, the tops of multiple support frames 33 are tightly fitted to the bottoms of multiple bottom connecting blocks 27, forming a stable support structure. During the line laying process, when the worker pulls the connecting end of the cable 3 to connect with the ship, the support frame 33 plays a crucial restrictive role. Under its restriction, the bottom connecting blocks 27 cannot move downwards, thus ensuring that the multiple guide wheels 23 are in a stable position. After the line laying is completed, the telescopic rod 36 is activated, which drives the foremost moving block 34 to slide along the inner wall of the inner groove seat 35. The sliding of the moving block 34 simultaneously drives the support frame 33 to move laterally, thereby removing the restriction on the foremost bottom connecting block 27. At this time, the first set of guide wheels 23 gains the freedom to move downwards, and can adjust and buffer the tension according to the tension generated by the ship's swaying to adapt to the dynamic changes of the ship. When the ship's swaying causes the first set of guide wheels 23 to descend to the lowest point, the magnetic component begins to play its role. Through the ingenious magnetic action of the magnetic component, it can release... In addition to the restriction relationship between the second set of support frames 33 and the corresponding bottom contact block 27, this means that the second set of guide wheels 23 can also move downwards when needed to further adjust the tension of the cable 3. Similarly, when the second set of guide wheels 23 descends to the lowest point, the corresponding magnetic component can continue to release the restriction of the subsequent support frame 33 on the corresponding bottom contact block 27, so that the subsequent guide wheels 23 can also participate in the tension adjustment process in turn. This mechanism of releasing restrictions in stages can gradually and orderly release the adjustment capability of the guide wheels 23 according to the degree of ship swaying and the change in the tension of the cable 3, avoiding the instability factors that may be caused by the simultaneous action of all guide wheels 23. At the same time, it also improves the flexibility and adaptability of the tension self-adjusting component, and can better cope with the influence of ship swaying on the tension of the cable 3 under different working conditions, ensuring that the mooring device always maintains a stable and reliable working state. If more guide wheels 23 descend and move to buffer self-adjust at the same time, it indicates that the ship's swaying amplitude is greater.

[0050] like Figure 6 and Figure 8 As shown, the magnetic component includes multiple magnet blocks 37, which are fixedly connected to the sides of multiple bottom blocks 27. Each side of multiple movable blocks 34 is fixedly connected to a magnet block 38, and the magnetic poles of each set of magnet blocks 37 and magnet blocks 38 that are close to each other have the same pole.

[0051] During operation: When the ship is rocked by wind and waves at sea, the tension in the cable 3 changes continuously. When the ship's rocking causes the first set of guide wheels 23 to descend to its lowest point, the descent of the bottom connecting block 27 drives the magnet block 37 connected to its side to gradually descend, approaching the corresponding magnet block 38 until they are parallel. Since the magnet block 38 is connected to the second set of moving blocks 34, when the magnet block 37 and the magnet block 38 enter the magnetic field, due to the repulsion between their like poles, they will squeeze the second set of moving blocks 34, causing it to slide along the inner wall of the corresponding inner groove seat 35. This allows the second set of support frames 33 to move laterally, releasing the restriction on the second set of guide wheels 23. At this point, the second set of guide wheels 23 can move freely up and down according to the tension generated by the ship's swaying, thereby further adjusting the tension of the cable 3. Similarly, when the second set of guide wheels 23 descends to its lowest point under the influence of factors such as the ship's continuous swaying, the side magnet block 37 of the bottom connecting block 27 connected to it will gradually descend and approach the next set of corresponding magnet blocks 38. Under the action of the repulsive magnetic force of like poles, it will squeeze the next set of moving blocks 34 to slide along the inner wall of the corresponding inner groove seat 35, thereby driving the corresponding support frame 33 to move laterally and releasing the restriction on the subsequent guide wheels 23. The subsequent guide wheels 23 can also participate in the adjustment process of the cable 3 tension in turn according to this logic.

[0052] like Figure 2 and Figure 8 As shown, a rainproof frame 41 is fixedly connected to the top of the bearing housing 1, a warning light 42 is fixedly connected to the top of the rainproof frame 41, a cleaning device 43 is provided on the inner side of the rainproof frame 41, and a warning component is provided below the last set of bottom connecting blocks 27, which can be triggered to make the warning light 42 emit a warning.

[0053] During operation: In the process of the tension self-adjusting component, multiple guide wheels 23 adjust the tension on the cable 3 in a graded manner. When the ship is swaying in a relatively stable state, only a few of the first few groups of guide wheels 23 participate in tension adjustment to adapt to slight tension changes. However, as the ship's swaying intensifies, more guide wheels 23 will sequentially engage in tension adjustment. If the sea encounters severe weather, with strong winds and large waves causing excessive ship swaying, the last group of guide wheels 23 will participate in tension adjustment and buffering of the cable 3 to better adapt to tension changes under such extreme conditions. As the tension caused by the ship's swaying continues to increase, the last group of guide wheels... The guide wheels 23 gradually descend under the pulling force; when the last set of guide wheels 23 is about to descend to the lowest point, it means that the tension adjustment of the tension self-adjusting component is about to reach its limit. When the last set of bottom connecting blocks 27 is about to descend to the lowest point, it will trigger the warning component set below it. Once the warning component is triggered, it will immediately send a signal to the warning light 42, causing the warning light 42 to emit a clear warning light, promptly alerting the staff that the current tension self-adjusting component is approaching its working limit and that they need to pay close attention to the condition of the cable 3 and the mooring status of the ship in order to take appropriate measures to avoid possible dangers and ensure the safety of the mooring device and the ship.

[0054] like Figure 2 and Figure 8 As shown, the warning component includes a trigger block 39, which is fixedly connected to one side of the last set of bottom contact blocks 27. A control button 40 is provided directly below the trigger block 39, and the control button 40 is fixedly connected to one side of the last set of inner slot seats 35.

[0055] During operation: When the last set of bottom contact blocks 27 is about to descend to the lowest point, the trigger block 39 fixed on one side of it is also close to the control button 40 fixed on one side of the inner groove seat 35 below; when the trigger block 39 descends to contact the control button 40, it will apply pressure to the control button 40, triggering the signal triggering mechanism inside the control button 40, and will immediately send an electrical signal to the warning light 42; after receiving the signal, the warning light 42 will respond quickly and emit a bright warning light to remind the staff.
