Description

Technical Field

[0001] This invention belongs to the field of anchor winches, specifically a marine anchor winch. Background Technology

[0002] An anchor is a key component of anchoring equipment. It is an iron device used to stop a ship. It is attached to the ship by an anchor chain. By dropping the anchor into the water, the ship can be brought to a stable stop. In order to ensure the flexible use of the anchor, an anchor winch needs to be installed on the ship to wind up and release the anchor chain, which is used for the release and retrieval of the anchor.

[0003] Anchor winches are deck machinery used on ships to raise and lower anchors and anchor chains. They are usually installed on the main deck at the bow and stern or on the forecastle deck, and have the functions of raising and lowering anchors and mooring lines. They are classified by power type as manual, electric, and hydraulic, and by layout as horizontal and vertical. Their core structure includes a sprocket, winch drum, clutch, braking device, and base support, and the anchor chain is operated by a main shaft.

[0004] Traditional anchor winches typically use take-up rollers to continuously rotate and wind up the anchor chain. However, as winding progresses, the later-wound anchor chain presses against the earlier-wound chain. Under immense radial pressure, the anchor chains rub and slide against each other, severely abrading their surface coatings or body materials. Simultaneously, the inner ring of the anchor chain, under continuous pressure from the outer ring, may undergo plastic deformation, no longer maintaining its original circular shape. Obvious indentations will appear at the contact points of adjacent chains. Uneven compression will create stress concentration points inside the chain, significantly reducing its fatigue life and causing it to break prematurely under loads far below design limits during subsequent use.

[0005] Therefore, the present invention provides a marine anchor winch. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a marine anchor winch, comprising a driving gear and a transmission gear that mesh with each other. The diameter of the driving gear is smaller than that of the transmission gear. A reduction motor for driving the driving gear to rotate is provided at one end of the driving gear. A transmission shaft is fixedly connected to the middle of the transmission gear. A winding reel is fixedly connected to the outer side of one end of the transmission shaft. The middle of the winding reel is used to fix the anchor chain. Multiple sets of through holes are provided on both sides of the winding reel. Multiple support bars that can be translated are provided on one side of the winding reel. The positions of the multiple support bars are adapted to the positions of the through holes.

[0008] By starting the geared motor, the drive gear rotates, which in turn drives the transmission gear and drive shaft. Since the diameter of the transmission gear is much larger than that of the drive gear, a reduction in torque occurs, effectively increasing the output force of the drive gear and slowing down the rotation speed. This allows for stable control of the winding reel's rotation. As the reel rotates, the anchor chain is continuously wound around the outer edge of the reel's center. The center width of the reel is matched to the diameter of the anchor chain, allowing for a smooth winding of three turns or more. A guide device can be installed on the outside of the equipment. The position of the anchor chain is finely adjusted by following the rotation of the winding reel, ensuring that the anchor chain is wound flat and evenly in the center of the reel. Once the center area is fully wound, as the reel continues to wind, support bars are pushed out from the through holes. After multiple support bars are pushed out, they form a circular winding surface on the outer side of the center of the reel. Subsequent anchor chains will wrap around this new winding surface. The gaps between adjacent support bars allow the anchor chains on adjacent winding surfaces to connect with each other. Once a new winding surface is also neatly covered, new support bars are pushed out again to form the next winding surface, until the anchor chain is fully wound. When the winding is complete, release the anchor chain by releasing the chain from the outside in, sequentially from the outside to the inside. Once released, allow the support bar to overflow onto the outside of the winding reel. This design ensures the anchor chain remains neatly wound without tangling, preventing later-wound chains from wrapping around earlier ones. This even distribution of force prevents excessive compression, preserving the chain's shape and coating, effectively reducing safety hazards and extending service life. Furthermore, traditional anchor-lifting equipment is equipped with a self-locking function, locking itself after winding or during slow release. The anchor chain is self-locking during deployment, but the core of the self-locking is generally only applied to the drive shaft. When the self-locking device fails, all the anchor chains are prone to rapid disengagement. However, the multi-layered winding surface formed by the support bars can prevent the anchor chains from disengaging when the drive shaft self-locking fails. This is because adjacent anchor chains are connected through the gaps in the support bars. Even if the anchor falls and the winding reel rotates under the influence of gravity when the self-locking fails, as long as the support bars are not released, the anchor chains will be stuck by the support bars and cannot disengage. This also stops the winding reel from rotating, further improving the safety of the equipment.

[0009] Preferably, the multiple through holes in each group are arranged in a ring at equal intervals, and the diameter of the ring formed by each group of through holes increases from the inside to the outside. Through the uniform arrangement of multiple through holes, the multiple winding surfaces formed by multiple support bars increase at equal intervals from the inside to the outside, and the distance between the multiple winding surfaces is exactly the thickness of the anchor chain. In this way, the winding space of the winding reel can be fully utilized, ensuring orderly winding while also ensuring the winding quality of the anchor chain.

[0010] Preferably, a movable electric telescopic rod is provided on the other side of the take-up reel. A magnetic block is fixed to the end of the electric telescopic rod, a telescopic cylinder is sleeved on the outside of the support bar, a blocking block is fixed to the rear end of the support bar, and a spring is fixed between the blocking block and the telescopic cylinder. The telescopic cylinder is fixed to the outside of the take-up reel. To control the translation of the support bar, when the support bar needs to be moved to the middle of the take-up reel, the electric telescopic rod is driven to extend, allowing the magnetic block to move to fit against the end of the support bar. After attraction, the support bar is translated and pulled out. After moving to the other side of the take-up reel, the support bar... With the end fixed, once one ring of support bars is secured, a winding surface is formed. Only a small number of electric telescopic rods are needed, and these rods are positioned appropriately. After the lower winding surface is fully wound, the electric telescopic rods begin to pull the support bars, gradually working as the anchor chain winds up. This ensures that the front support bars are just secured when the anchor chain winds up. Simultaneously, the electric telescopic rods can move to accommodate the pulling of support bars at different positions. When the support bars are released, the springs allow them to quickly return to the telescopic cylinder, allowing the anchor chain to be released normally.

[0011] Preferably, a hook is fixed to the end of the support bar, and multiple hook rods adapted to the number of through holes are fixed to the side of the winding reel away from the telescopic cylinder. The hook rods are located below the through holes, and the ends of the hook rods are bent. The hook ring is made of a magnetizable metal material. To ensure the stable fixing effect of the support bar, the end of the hook ring is attracted by a magnetic block and pulled through the through hole. At this time, it will come above the hook rod. The electric telescopic rod is controlled to move, pressing down the magnetic block and the hook ring, so that the hook ring hooks the hook rod. Then the magnetic block continues to move down. The magnetic block is moved away from the hook and shackle until it detaches from the hook and shackle. This ensures the hook and shackle remain connected to the hook rod. To remove the hook and shackle, reverse the process: first, attract the hook and shackle from the bottom, then pull it down and move it away from the hook rod to remove it. The bend at the end of the hook rod ensures that the hook and shackle remain stably connected to the hook rod under normal pulling, preventing detachment and creating a stable and sturdy winding surface. Furthermore, the winding reel itself is made of non-magnetic material and will not attract the magnetic block, reducing operational resistance.

[0012] Preferably, the support bar is formed by spirally winding multiple steel cables, and the outer side of the support bar is also wrapped with multiple segments of collars for shaping. The hook is also formed by winding steel cables. The support bar is formed by winding high-strength steel cables, which not only has high strength but also has a certain deformation capacity. Since anchor chains are generally composed of chain links, the surface in contact with the winding surface is often not flat enough during the winding process. If a traditional fixed winding surface is used, it is easy to cause uneven stress. However, the support bar woven with steel cables will deform slightly when in contact with the anchor chain to adapt to the shape of the anchor chain, increase the pressure area, reduce local pressure, and thus protect the anchor chain and reduce the problem of excessive local pressure leading to deformation and damage to the anchor chain.

[0013] Preferably, a rotating shaft is installed on the outer side of the drive shaft. The rotating shaft is located between the take-up reel and the drive gear. Two electric lifting frames are fixedly connected to the outer side of the rotating shaft. The moving end of the electric lifting frame is fixedly connected to the outer side of the electric telescopic rod. The two electric lifting frames are fixedly connected by a series frame, and a gear ring is fixedly connected between the tops of the two electric lifting frames. An electric gear meshes with the outer side of the gear ring. The electric lifting frames control the electric telescopic rod to move vertically to adapt to the through holes at different positions. Multiple electric lifting frames and electric telescopic rods can be set to perform rapid support bar pull-out. During the take-up process, the electric lifting frames remain stationary. As the take-up reel rotates, whenever the through hole moves to align with the magnetic block, the support bar is pulled out, and the take-up process is temporarily stopped. When releasing the anchor chain, the electric gear drives the gear ring to rotate, allowing the electric telescopic rod to quickly contact and fix one ring of support bar, allowing the support bar to be fully retracted and returned to its original position, and allowing the anchor chain to be released normally.

[0014] Preferably, a sealing frame is fitted around the outer side of the winding reel, and an inlet for the anchor chain to pass through is provided on the outer side of the sealing frame. A power frame is fitted around the outer side of the gear ring, and the power frame is fixedly connected to the sealing frame. The electric gear is installed in the power frame. A protective frame is fixedly connected to the side of the sealing frame away from the power frame. The drive shaft is connected to the middle of the protective frame. The internal parts are protected by the sealing frame, the power frame, and the protective frame to reduce interference from the external environment.

[0015] Preferably, a support seat one is fixedly connected to the bottom of the sealing frame, the reduction motor is fixedly connected to the support seat one, and the outer side of the central shaft of the drive gear and the transmission shaft are rotatably connected to the support seat two, thereby improving the support stability of the equipment through the support seat one and the support seat two.

[0016] Preferably, the top surface of the sealing frame has two injection holes, the bottom of the sealing frame has a drain valve, and both ends of the chain inlet are rotatably connected to auxiliary rollers. Since the anchor chain is immersed in seawater for a long time, in order to reduce corrosion, cleaning fluid can be injected into the injection holes after winding to remove corrosive fluids such as seawater. Drying airflow can also be connected to ensure the dryness of the anchor chain. The moisture is discharged from the bottom drain valve. Since the internal anchor chain is neatly arranged and there are gaps between the multiple through holes, airflow and water can pass through smoothly and complete the thorough cleaning. Coating liquid can also be injected directly into the interior to simply cover the surface of the anchor chain with a coating before each sea trip to reduce seawater erosion. After coating is completed, the liquid is discharged through the drain valve.

[0017] Preferably, the end of the drive gear away from the reduction motor is connected to an auxiliary winding roller. The surface of the auxiliary winding roller has multiple winding spaces. Both ends of the auxiliary winding roller are equipped with support seats. The auxiliary winding roller can be used for other winding tasks such as mooring and winding mooring ropes.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The marine anchor winch of this invention, by setting multiple different windings in the winding roller, keeps the anchor chain in a neat and non-tangled winding state, preventing the phenomenon of the later winding anchor chain wrapping around the outside of the earlier winding anchor chain. This ensures that the anchor chain is subjected to uniform force, avoiding excessive compression, maintaining its shape and coating, effectively reducing safety hazards, and improving service life. Furthermore, traditional anchor winch equipment is equipped with a self-locking function, locking itself after winding or during the slow release of the anchor chain. However, the core of the self-locking is generally only applied to the drive shaft. When the self-locking device fails, all anchor chains are prone to rapid detachment and release. The multi-layer winding surface formed by the support bars can prevent the anchor chain from detaching even if the drive shaft self-locking fails. Because adjacent anchor chains are connected through the gaps in the support bars, even if the anchor falls and the winding reel rotates under gravity when the self-locking fails, as long as the support bars are not released, the anchor chain will be stuck and unable to detach, and the winding reel will stop rotating, further improving the safety of the equipment.

[0020] 2. The marine anchor winch of the present invention uses a support bar formed by winding high-strength steel cable. This support bar is not only high in strength but also possesses a certain degree of deformation capability. Since anchor chains are generally composed of chain links, the surface in contact with the winding surface is often not flat enough during the winding process. Using a traditional fixed winding surface can easily lead to uneven stress distribution. However, the steel cable-woven support bar deforms slightly when in contact with the anchor chain, adapting to the shape of the anchor chain, increasing the pressure-bearing area, and reducing localized pressure. This protects the anchor chain and reduces the problem of excessive localized pressure causing deformation and damage to the anchor chain. Attached Figure Description

Detailed Implementation

[0031] 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.

[0032] like Figures 1 to 8As shown in the embodiment of the present invention, a marine anchor winch includes a driving gear 2 and a transmission gear 1 that mesh with each other. The diameter of the driving gear 2 is smaller than that of the transmission gear 1. A reduction motor 7 for driving the driving gear 2 to rotate is provided at one end of the driving gear 2. A transmission shaft 14 is fixedly connected to the middle of the transmission gear 1. A winding reel 19 is fixedly connected to the outer side of one end of the transmission shaft 14. The middle of the winding reel 19 is used to fix the anchor chain 6. Multiple sets of through holes 20 are opened on both sides of the winding reel 19. Multiple support bars 25 that can be translated are provided on one side of the winding reel 19. The positions of the multiple support bars 25 are adapted to the positions of the through holes 20.

[0033] By starting the reduction motor 7, the drive gear 2 is rotated, which in turn drives the transmission gear 1 and the transmission shaft 14 to rotate. Since the diameter of the transmission gear 1 is much larger than the diameter of the drive gear 2, a reduction in torque occurs, effectively increasing the output force of the drive gear 2 and slowing down the rotation speed. This allows for stable control of the winding reel 19 for winding. As the winding reel 19 rotates, the anchor chain 6 is continuously wound around the outer side of the center of the winding reel 19. The center width of the winding reel 19 is matched with the diameter of the anchor chain 6, allowing for a smooth winding of three or more turns of the anchor chain 6. A guide device can be installed on the outside of the equipment. The position of the anchor chain 6 is finely adjusted by rotating the winding reel 19 to ensure that the anchor chain 6 is neatly wound up in the center of the winding reel 19. Once the center is fully wound up, as the winding reel 19 continues to wind, the support bars 25 are pushed out from the through holes 20. Multiple support bars 25, once pushed out, form a circular winding surface on the outer side of the center of the winding reel 19. Subsequent anchor chains 6 will wrap around this new winding surface. The gaps between adjacent support bars 25 allow the anchor chains 6 on adjacent winding surfaces to connect with each other. Once the new winding surface is also neatly covered, new support bars 25 are pushed out again to form the next winding surface, and so on. When the anchor chain 6 is fully wound up, release it by releasing the anchor chain 6 sequentially from the outside in. After release, allow the support bar 25 to overflow to the outside of the winding reel 19. This design ensures that the anchor chain 6 remains neatly wound without tangling, preventing the later-wound anchor chain 6 from wrapping around the earlier-wound anchor chain 6. This ensures even stress distribution on the anchor chain 6, preventing excessive compression and maintaining its shape and coating. This effectively reduces safety hazards and extends service life. Furthermore, traditional anchor-raising equipment is equipped with a self-locking function, locking itself after winding or during slow release. The anchor chain 6 is self-locking, but the core of the self-locking is generally only applied to the drive shaft 14. When the self-locking device fails, all the anchor chains 6 are prone to rapid disengagement. However, the multi-layer winding surface formed by the support bar 25 can prevent the anchor chains 6 from disengaging when the self-locking of the drive shaft 14 fails. This is because adjacent anchor chains 6 are connected through the gaps in the support bar 25. When the self-locking fails, even if the anchor falls and the winding reel 19 rotates under the action of gravity, as long as the support bar 25 is not released, the anchor chains 6 will be stuck by the support bar 25 and cannot disengage. It can also stop the winding reel 19 from rotating, further improving the safety of the equipment.

[0034] The multiple through holes 20 in each group are arranged in a ring at equal intervals, and the diameter of the ring formed by each group of through holes 20 increases from the inside to the outside.

[0035] During operation, the multiple through holes 20 are evenly arranged so that the multiple winding surfaces formed by the multiple support bars 25 increase in size from the inside out, and the spacing between the multiple winding surfaces is exactly the thickness of the anchor chain 6. This makes full use of the winding space of the winding reel 19, ensuring orderly winding while also ensuring the winding quality of the anchor chain 6.

[0036] On the other side of the take-up reel 19, there is a movable electric telescopic rod 24. A magnetic block 27 is fixed to the end of the electric telescopic rod 24. A telescopic cylinder 18 is sleeved on the outside of the support bar 25. A blocking block is fixed to the rear end of the support bar 25. A spring is fixed between the blocking block and the telescopic cylinder 18. The telescopic cylinder 18 is fixed to the outside of the take-up reel 19.

[0037] During operation, to control the translation of the support bar 25, when the support bar 25 needs to be moved to the middle of the take-up reel 19, the electric telescopic rod 24 is extended by driving it, allowing the magnetic block 27 to move and adhere to the end of the support bar 25. After adsorption, the support bar 25 is translated and pulled out. After moving to the other side of the take-up reel 19, the end of the support bar 25 is fixed. After one ring of support bars 25 is fixed, a row of take-up surfaces is formed. Only a small number of electric telescopic rods 24 need to be set, and the electric telescopic rods 24 are set... At the appropriate position, after the lower winding surface is fully wound, the electric telescopic rod 24 begins to pull the support bar 25, and gradually proceeds as the anchor chain 6 is wound up, so that when the anchor chain 6 is wound up, the front support bar 25 is just fixed. At the same time, the electric telescopic rod 24 can move to adapt to the pulling work of the support bar 25 in different positions. When the support bar 25 is released from its fixed position, under the action of the spring, the support bar 25 will quickly return to the telescopic cylinder 18, allowing the anchor chain 6 to be released outward normally.

[0038] The end of the support bar 25 is fixedly connected to a hook ring 26. The side of the winding reel 19 away from the telescopic cylinder 18 is fixedly connected to a plurality of hook rods 21 that match the number of through holes 20. The hook rods 21 are located below the through holes 20, and the ends of the hook rods 21 are bent. The hook ring 26 is made of a magnetizable metal material.

[0039] During operation, to ensure the stable fixation of the support bar 25, the end of the hook ring 26 is attracted by the magnetic block 27 and pulled through the through hole 20, thus reaching above the hook rod 21. The electric telescopic rod 24 is then moved to press down the magnetic block 27 and the hook ring 26, allowing the hook ring 26 to hook onto the hook rod 21. The magnetic block 27 then continues to move downwards until it detaches from the hook ring 26. Finally, the magnetic block 27 moves horizontally away from the hook ring 26, thus ensuring the hook ring 26 remains connected to the hook rod 21. When it is necessary to remove the hook 26, the operation is reversed. First, the hook 26 is attracted from the bottom, then the hook 26 is pulled down, and then it is moved away from the hook rod 21 to complete the removal of the hook 26. With the bending setting at the end of the hook rod 21, it can be ensured that the hook 26 is stably connected to the hook rod 21 under normal pulling and cannot be detached, thus forming a stable and solid winding surface. At the same time, the winding reel 19 itself is a non-magnetic material and will not be attracted to the magnetic block 27, reducing the operating resistance.

[0040] The support bar 25 is formed by spirally winding multiple steel cables, and the outer side of the support bar 25 is also wrapped with multiple sections of collars for shaping. The hook 26 is also formed by winding steel cables.

[0041] During operation, the support bar 25 is formed by winding high-strength steel cables. It is not only strong but also has a certain degree of deformation capability. Since the anchor chain 6 is generally composed of chain links, the surface in contact with the winding surface is often not flat enough during the winding process. If a traditional fixed winding surface is used, it is easy to cause uneven stress. However, when the steel cable braided support bar 25 comes into contact with the anchor chain 6, it will deform slightly to adapt to the shape of the anchor chain 6, increase the pressure-bearing area, reduce local pressure, and thus protect the anchor chain 6, reducing the problem of excessive local pressure leading to deformation and damage to the anchor chain 6.

[0042] A rotating shaft 22 is installed on the outside of the drive shaft 14. The rotating shaft 22 is located between the take-up reel 19 and the drive gear 1. Two electric lifting frames 15 are fixedly connected to the outside of the rotating shaft 22. The moving end of the electric lifting frame 15 is fixedly connected to the outside of the electric telescopic rod 24. The two electric lifting frames 15 are fixedly connected to each other through a series frame 23. A gear ring 16 is fixedly connected between the tops of the two electric lifting frames 15. An electric gear is meshed on the outside of the gear ring 16.

[0043] During operation, the electric lifting frame 15 controls the electric telescopic rod 24 to move vertically, adapting to different positions of the through hole 20. Multiple electric lifting frames 15 and electric telescopic rods 24 can be set up to quickly pull out the support bar 25. During the winding process, the electric lifting frame 15 remains stationary. As the winding reel 19 rotates, whenever the through hole 20 moves to align with the magnetic block 27, the support bar 25 is pulled out, and the winding process is temporarily stopped. When releasing the anchor chain 6, the electric gear drives the gear ring 16 to rotate, allowing the electric telescopic rod 24 to quickly contact and fix one ring of support bar 25, so that the support bar 25 can be fully retracted and returned to its position, allowing the anchor chain 6 to be released normally.

[0044] A sealing frame 3 is fitted around the outer side of the winding reel 19. An inlet 12 for the anchor chain 6 to pass through is opened on the outer side of the sealing frame 3. A power frame 5 is fitted around the outer side of the gear ring 16. The power frame 5 is fixedly connected to the sealing frame 3. The electric gear is installed in the power frame 5. A protective frame 4 is fixedly connected to the side of the sealing frame 3 away from the power frame 5. The drive shaft 14 is connected to the middle of the protective frame 4. During operation, the internal parts are protected by the sealing frame 3, the power frame 5 and the protective frame 4 to reduce interference from the external environment.

[0045] The bottom of the sealing frame 3 is fixedly connected to a support seat 8, the geared motor 7 is fixedly connected to the support seat 8, and the central shaft of the drive gear 2 and the outer side of the transmission shaft 14 are both rotatably connected to a support seat 9. During operation, the support stability of the equipment is improved by the support seat 8 and the support seat 9.

[0046] The top surface of the sealing frame 3 has two injection holes 13, the bottom of the sealing frame 3 has a drain valve, and both ends of the chain inlet 12 are rotatably connected to auxiliary rollers 17.

[0047] During operation, since the anchor chain 6 is immersed in seawater for a long time, in order to reduce corrosion, cleaning fluid can be injected into the injection hole 13 after winding to remove corrosive fluids such as seawater. Drying airflow can also be connected to ensure the dryness of the anchor chain 6. The moisture is discharged from the bottom drain valve. Since the internal anchor chain 6 is neatly arranged and there are gaps between the multiple through holes 20, airflow and water can pass through smoothly and complete the thorough cleaning. Coating liquid can also be injected directly into the interior to simply cover the surface of the anchor chain 6 with a coating before each sea trip to reduce seawater erosion. After the coating is completed, the liquid is discharged through the drain valve.

[0048] The end of the drive gear 2 away from the reduction motor 7 is connected to an auxiliary winding roller 10. The surface of the auxiliary winding roller 10 has multiple winding spaces. Both ends of the auxiliary winding roller 10 are equipped with support seats 3 11. During operation, the auxiliary winding roller 10 can be used for other winding tasks such as mooring and winding mooring ropes.

[0049] During operation, the geared motor 7 drives the drive gear 2 to rotate, which in turn drives the transmission gear 1 and the transmission shaft 14 to rotate. Since the diameter of the transmission gear 1 is much larger than that of the drive gear 2, a reduction in torque occurs, effectively increasing the output force of the drive gear 2 and slowing down the rotation speed. This allows for stable control of the winding reel 19 for winding. As the winding reel 19 rotates, the anchor chain 6 is continuously wound around the outer edge of the center of the reel 19. The center width of the winding reel 19 is matched to the diameter of the anchor chain 6, allowing for a smooth winding of three turns or more of the anchor chain 6. A guide can be installed on the outside of the equipment. The guide device, following the rotation of the winding reel 19, fine-tunes the position of the anchor chain 6, ensuring that the anchor chain 6 can be neatly wound up in the center of the winding reel 19. Once the center area is fully wound up, as the winding reel 19 continues to wind, the control support bars 25 are pushed out from the through holes 20. Multiple support bars 25, once pushed out, form a circular winding surface on the outer side of the center of the winding reel 19. Subsequent anchor chains 6 will wrap around this new winding surface. The gaps between adjacent support bars 25 allow the anchor chains 6 on adjacent winding surfaces to connect with each other. Once the new winding surface is also neatly covered, new support bars 25 are pushed out again to form the next winding surface. The anchor chain 6 is wound up until it is completely unwound. When releasing the anchor chain 6, simply release the anchor chain 6 on the winding surface sequentially from the outside to the inside. After release, allow the support bar 25 to overflow to the outside of the winding reel 19. This design ensures that the anchor chain 6 remains neatly wound without tangling, preventing the later-wound anchor chain 6 from wrapping around the outside of the earlier-wound anchor chain 6. This ensures that the anchor chain 6 is evenly stressed and not subjected to excessive compression, preserving its shape and coating, effectively reducing safety hazards, and improving service life. Furthermore, traditional anchor-lifting equipment is equipped with a self-locking function, which locks itself after winding is complete or during slow release. The anchor chain 6 is self-locking, but the core of the self-locking is generally only applied to the drive shaft 14. When the self-locking device fails, all the anchor chains 6 are prone to rapid disengagement. However, the multi-layer winding surface formed by the support bars 25 can prevent the anchor chains 6 from disengaging when the self-locking of the drive shaft 14 fails. This is because adjacent anchor chains 6 are connected through the gaps in the support bars 25. When the self-locking fails, even if the anchor falls and the winding reel 19 rotates under the action of gravity, as long as the support bars 25 are not released, the anchor chains 6 will be stuck by the support bars 25 and cannot disengage. It can also stop the winding reel 19 from rotating, further improving the safety of the equipment.

[0050] By evenly arranging multiple through holes 20, the multiple winding surfaces formed by multiple support bars 25 increase in size from the inside out, and the spacing between the multiple winding surfaces is exactly the thickness of the anchor chain 6. This makes full use of the winding space of the winding reel 19, ensuring orderly winding while also guaranteeing the winding quality of the anchor chain 6.

[0051] To control the translation of the support bar 25, when the support bar 25 needs to be moved to the middle of the winding reel 19, the electric telescopic rod 24 is extended by driving it, allowing the magnetic block 27 to move and adhere to the end of the support bar 25. After adsorption, the support bar 25 is translated and pulled out. After moving to the other side of the winding reel 19, the end of the support bar 25 is fixed. When one ring of support bar 25 is fixed, a winding surface is formed. Only a small number of electric telescopic rods 24 need to be set and set in appropriate positions. After the lower winding surface is fully wound, the electric telescopic rods 24 begin to pull the support bar 25. This is done gradually as the anchor chain 6 is wound, so that when the anchor chain 6 is wound, the support bar 25 in front is just fixed. At the same time, the electric telescopic rods 24 can move to adapt to the pulling of the support bar 25 in different positions. When the support bar 25 is released from its fixed position, it will quickly return to the telescopic cylinder 18 under the action of the spring, allowing the anchor chain 6 to be released normally.

[0052] To ensure the stable fixing effect of the support bar 25, the end of the hook ring 26 is attracted by the magnetic block 27 and pulled through the through hole 20. At this time, it will come to the top of the hook rod 21. The electric telescopic rod 24 is controlled to move, pressing down the magnetic block 27 and the hook ring 26 so that the hook ring 26 hooks the hook rod 21. Then the magnetic block 27 continues to move down until it is detached from the hook ring 26. Then the magnetic block 27 moves away from the hook ring 26, thus ensuring that the hook ring 26 is connected to the hook rod 21. When the hook 26 needs to be removed, the operation is reversed. First, the hook 26 is attracted from the bottom, then the hook 26 is pulled down, and then it is moved away from the hook rod 21 to complete the removal of the hook 26. With the bending design at the end of the hook rod 21, the hook 26 can be stably connected to the hook rod 21 under normal pulling and cannot be detached, thus forming a stable and sturdy winding surface. At the same time, the winding reel 19 itself is made of non-magnetic material and will not be attracted to the magnetic block 27, reducing the operating resistance.

[0053] The support bar 25 is formed by winding high-strength steel cable. It is not only strong but also has a certain degree of deformation. Since the anchor chain 6 is generally composed of chain links, the surface in contact with the winding surface is often not flat enough during the winding process. If the traditional fixed winding surface is used, it is easy to cause uneven stress. However, the support bar 25 woven from steel cable will deform slightly when it comes into contact with the anchor chain 6, adapting to the shape of the anchor chain 6, increasing the pressure-bearing area, reducing local pressure, thereby protecting the anchor chain 6 and reducing the problem of excessive local pressure leading to deformation and damage to the anchor chain 6.

[0054] The electric lifting frame 15 controls the electric telescopic rod 24 to move vertically, adapting to different positions of the through hole 20. Multiple electric lifting frames 15 and electric telescopic rods 24 can be set up to quickly pull out the support bar 25. During the winding process, the electric lifting frame 15 remains stationary. As the winding reel 19 rotates, whenever the through hole 20 moves to align with the magnetic block 27, the support bar 25 is pulled out, and the winding process is temporarily stopped. When releasing the anchor chain 6, the electric gear drives the gear ring 16 to rotate, allowing the electric telescopic rod 24 to quickly contact and fix one ring of support bar 25, so that the support bar 25 can be fully retracted and returned to its position, allowing the anchor chain 6 to be released normally.

[0055] Since the anchor chain 6 is immersed in seawater for a long time, in order to reduce corrosion, cleaning fluid can be injected into the injection hole 13 after winding to remove corrosive fluids such as seawater. Drying airflow can also be connected to ensure the dryness of the anchor chain 6. The moisture is discharged from the bottom drain valve. Because the internal anchor chain 6 is neatly arranged and there are gaps between the multiple through holes 20, airflow and water can pass through smoothly and complete the thorough cleaning. Coating liquid can also be injected directly into the interior to simply cover the surface of the anchor chain 6 with a coating before each sea trip to reduce seawater erosion. After the coating is completed, the liquid is discharged through the drain valve.
