Description

[0002] Anchor chain is one of the important mooring equipment, which plays a very important role in the safe mooring of ships and resistance to external forces. Considering the safety of anchoring, anchor chain is generally used as the anchor cable of ships. However, for self-unloading sand ships, crane ships, pile-driving ships and other ships with similar operations, wire rope is often used instead of anchor chain, such as fixed target work ships.

[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] The embodiment of the present invention provides a combined anchor cable rotating fairlead, such as Figure 1-13 As shown, the combined anchor cable rotating fairlead includes: a mounting seat 2 arranged on the ship body 1; a vertical roller 3 rotatably mounted on the mounting seat 2, the vertical roller 3 is used to limit the steel wire rope and guide it through the mounting seat 2; a first horizontal roller 4 rotatably mounted on one side of the vertical roller 3, the first horizontal roller 4 is used to horizontally guide the steel wire rope; an active roller 6 and a motor 11 arranged above the mounting seat 2, the active roller 6 is driven by the motor 11 and is used to actively pull the steel wire rope; a limiting mechanism arranged on one side of the ship body 1 for limiting the steel wire rope; a cleaning mechanism arranged on one side of the support plate 5 for cleaning the steel wire rope.

[0036] In this embodiment, when it is necessary to drop anchor, the anchor winch on the ship body 1 is first started to release the wire rope, and at the same time, the wire rope slides along the first horizontal roller 4, the active roller 6, the second horizontal roller 8 and the limit roller 9, so that the anchor slides down along the limit roller 9, thereby dropping anchor. When the wire rope slides, the first horizontal roller 4, the active roller 6, the second horizontal roller 8 and the limit roller 9 rotate at the same time, so that they roll and rub the wire rope, which can reduce the wear of the wire rope;

[0037] When it is necessary to raise the anchor, first start the anchor winch to make it reel in the wire rope, and at the same time the wire rope slides along the first horizontal roller 4, the active roller 6, the second horizontal roller 8 and the limit roller 9. While reeling in the wire rope, start the cleaning mechanism to make it pre-clean the impurities on the wire rope, thereby reducing the organisms or impurities attached to the wire rope. By setting the first horizontal roller 4, the active roller 6 and the limit mechanism which are mainly based on rolling friction when in contact with the wire rope and moving relative to it, the friction coefficient and the degree of wear of the wire rope can be greatly reduced, and the service life of the wire rope can be significantly extended. At the same time, the wire rope can be retracted and released more smoothly, and the operation interruption or delay caused by the increase of friction resistance is reduced, thereby improving the overall operation efficiency. The design of the stable mounting seat 2 and the support plate 5 ensures the stability and reliability of the entire cable guide system during operation, and reduces the risk of failure due to vibration or impact.

[0038] In a further preferred embodiment of the present invention, the limiting mechanism includes: a bracket 7 installed on one side of the ship body 1; a second horizontal roller 8 provided at one end of the bracket 7 for vertically guiding the wire rope; a limiting roller 9 installed on the top of the bracket 7 for limiting the anchor, and the limiting roller 9 is located above the second horizontal roller 8.

[0039] In this embodiment, the second horizontal roller 8 reduces the friction of the wire rope during the turning process through rolling contact to ensure that the wire rope can slide smoothly. The main function of the limit roller 9 is to guide the movement of the wire rope in the vertical direction to prevent the wire rope from deviating from the predetermined path or colliding with other components unnecessarily during the lifting process. The rolling contact of the limit roller 9 further reduces the friction resistance of the wire rope in the vertical movement. Through the combined action of the second horizontal roller 8 and the limit roller 9, the limiting mechanism can more accurately control the movement trajectory of the wire rope to prevent it from exceeding the safety range or interfering with other equipment components. At the same time, the second horizontal roller 8 and the limit roller 9 are added to the original active roller system to convert the conventional wire rope guiding method from sliding friction to rolling friction, thereby reducing the overall friction coefficient and wear degree.

[0040] In a further preferred embodiment of the present invention, a connecting seat is rotatably installed on one side of the support plate 5, and the connecting seat is slidably connected to the output rod of the active roller 6. The output rod of the connecting seat extends out of one side of the support plate 5. The connecting seat and one side of the support plate 5 are both provided with connecting gears 10, and multiple connecting gears 10 are meshed with each other. A motor 11 is fixedly installed on one side of the support plate 5, and the output shaft of the motor 11 is fixedly connected to the output rod of the connecting seat.

[0041] In this embodiment, while the wire rope slides along the active roller 6, the motor 11 is started, so that the output shaft of the motor 11 drives the connecting gear 10 to rotate, so that the connecting gear 10 drives the connecting seat to rotate synchronously, so that the connecting seat drives the active roller 6 to rotate, and the surface of the active roller 6 is in rolling contact with the wire rope, thereby reducing the wear of the wire rope. The rotation operation of the active roller 6 is realized by the drive of the motor 11 and the gear transmission, thereby facilitating the guiding operation of the wire rope.

[0042] In a further preferred embodiment of the present invention, a protective box 12 is installed on one side of the support plate 5 , and the protective box 12 covers the motor 11 . A notch is provided at the bottom of the protective box 12 , and the notch is matched with the connecting gear 10 .

[0043] In this embodiment, the protective box 12 is covered on the motor 11 to provide physical protection for the motor 11. The protective box 12 can effectively prevent external impurities, moisture or accidental collisions from damaging the motor 11, thereby ensuring the normal operation of the motor 11 and extending its service life. The protective box 12 provides an effective physical barrier for the motor 11, preventing direct damage to the motor 11 by external factors, helping to reduce the failure rate of the motor 11 and improve the reliability and stability of the system.

[0044] In a further preferred embodiment of the present invention, the cleaning mechanism includes: a support frame 13 fixedly mounted on the top of the bracket 7, the support frame 13 is located between the support plate 5 and the limiting roller 9; an annular water pipe 14 and a mounting frame 15 both mounted on the top of the support frame 13, the annular water pipe 14 is located between the mounting frame 15 and the limiting roller 9; and a group of cleaning brushes 16 both arranged in the mounting frame 15.

[0045] In this embodiment, when anchoring, the annular water pipe 14 is connected to the high-pressure water pump on the ship body 1, so that the high-pressure water pump draws seawater into the annular water pipe 14, and the annular water pipe 14 sprays high-pressure water on the wire rope, thereby cleaning the organisms or impurities attached to the wire rope. At the same time, a group of cleaning brushes 16 rotate to clean the surface of the wire rope, thereby effectively reducing the objects attached to the wire rope. By combining the high-pressure spraying of the annular water pipe 14 and the physical brushing action of the cleaning brush 16, the cleaning mechanism can quickly remove impurities and attached organisms on the surface of the wire rope. This dual cleaning method significantly improves the cleaning efficiency and extends the service life of the wire rope. At the same time, the automated design of the cleaning mechanism reduces the need for manual cleaning and reduces labor intensity. At the same time, since the cleaning process is more efficient and thorough, it also reduces equipment failures and downtime caused by incomplete cleaning, and also helps to keep the surface of the wire rope clean and smooth, reducing the wear and damage of equipment components (such as active roller 6, limit roller 9, etc.) caused by the accumulation of impurities and wear materials.

[0046] In a further preferred embodiment of the present invention, a group of connecting plates 17 are fixedly installed in the mounting frame 15, a group of rectangular tubes 18 are rotatably installed on each of the connecting plates 17, a group of mounting plates 19 are slidably provided on each of the rectangular tubes 18, a group of mounting plates 19 are detachably connected to a group of cleaning brushes 16, and a group of rotating rods 20 are rotatably installed in the mounting frame 15, a group of rotating rods 20 and an output rod of the rectangular tube 18 are fixedly sleeved with bevel gears 21, and a plurality of the bevel gears 21 are meshed with each other.

[0047] In this embodiment, when it is necessary to clean the wire rope, the first electric telescopic rod 27 is first started, so that the output rod of the first electric telescopic rod 27 drives the mounting plate 19 to slide up, so that the output rod smoke rectangular tube 18 of the mounting plate 19 slides, thereby adjusting the distance between a group of cleaning brushes 16 to make them close to and contact the wire rope, and then a group of rotating rods 20 are rotated, and then the rotating rods 20 drive the bevel gear 21 to rotate, so that the bevel gear 21 drives the rectangular tube 18 to rotate, so that the rectangular tube 18 drives the cleaning brush 16 on the mounting plate 19 to rotate, and the cleaning brush 16 rotates to clean the wire rope, and the cleaning efficiency is high. Through the design of the rectangular tube 18 and the mounting plate 19, the position and angle of the cleaning brush 16 can be flexibly adjusted to adapt to wire ropes of different diameters and motion trajectories. This flexibility improves the versatility and adaptability of the cleaning mechanism. Through the transmission design of the rotating rod 20 and the bevel gear 21, a group of cleaning brushes 16 can rotate synchronously and efficiently to comprehensively and evenly brush the wire rope. Through the detachable connection design between the cleaning brush 16 and the mounting plate 19, the replacement and maintenance of the cleaning brush 16 becomes simple and quick. When the cleaning brush 16 is severely worn, it can be quickly replaced with a new cleaning brush 16 without disassembling the entire cleaning mechanism.

[0048] In a further preferred embodiment of the present invention, a group of the connecting plates 17 are each provided with a connecting port, a group of the rotating rods 20 are each provided with a first sprocket 22, a group of the first sprockets 22 are provided with a first chain 23, the first chain 23 is meshed with a group of the first sprockets 22 and passes through the connecting port, one end of any of the rotating rods 20 extends out of the mounting frame 15, a bracket 24 is installed on one side of the mounting frame 15, the bracket 24 is rotatably connected to the rotating rod 20, the rotating rod 20 and any of the connecting gears 10 are each fixedly provided with a differential wheel 25, a group of the differential wheels 25 are provided with a second chain 26, and the second chain 26 is meshed with a group of differential wheels 25.

[0049] The second chain 26 is driven by the differential wheel 25 to rotate synchronously, thereby the differential wheel 25 drives the second chain 26 to rotate synchronously, so that the differential wheel 25 drives the rotating rod 20 to rotate, and the rotating rod 20 drives the rectangular cylinder 18 to rotate, thereby realizing the rotation operation of the cleaning brush 16. At the same time, the rotating rod 20 drives the first sprocket 22 to rotate while rotating, so that the first sprocket 22 drives the first chain 23 to rotate, thereby realizing the synchronous rotation operation of a group of rotating rods 20, which is beneficial to the cleaning operation of the wire rope. Through the combination of the first chain 23 and the first sprocket 22, the synchronous rotation of a group of rotating rods 20 is realized, ensuring that a group of cleaning brushes 16 can brush the wire rope simultaneously and evenly, thereby improving the cleaning efficiency. The design of the differential wheel 25 and the second chain 26 enables the active roller 6 to drive a group of cleaning brushes 16 to rotate while rotating, thereby facilitating the cleaning operation of the wire rope.

[0050] In a further preferred embodiment of the present invention, a first electric telescopic rod 27 is installed on the top of the connecting plate 17, and an annular frame 28 is installed on the output rod of the first electric telescopic rod 27. The annular frame 28 is sleeved on the mounting plate 19, and a roller 29 is installed on one side of the mounting plate 19, and the roller 29 is in contact with one side of the inner wall of the annular frame 28.

[0051] In this embodiment, when performing anchoring operations, the first electric telescopic rod 27 is started, so that the output rod of the first electric telescopic rod 27 drives the annular frame 28 to slide down, and the annular frame 28 drives the mounting plate 19 to slide down, so that the cleaning brush 16 slides away from the wire rope, reducing unnecessary friction of the cleaning brush 16, thereby extending the service life of the cleaning brush 16. Through the telescopic movement of the first electric telescopic rod 27, the height position of the mounting plate 19 and the cleaning brush 16 thereon can be easily adjusted. This flexible adjustment capability enables the cleaning mechanism to adapt to wire ropes of different diameters and positions, thereby improving the pertinence and effectiveness of cleaning. The introduction of the roller 29 reduces the direct friction between the mounting plate 19 and the annular frame 28, thereby reducing the degree of wear, helping to extend the service life of the cleaning mechanism and reduce the noise and vibration caused by wear. By accurately adjusting the height position of the cleaning brush 16, it can be ensured that the cleaning brush 16 maintains appropriate contact force and angle with the surface of the wire rope, which helps to improve the cleaning quality and make the surface of the wire rope cleaner and smoother.

[0052] In a further preferred embodiment of the present invention, a connecting plate 30 is detachably installed on one side of the active roller 6, a second electric telescopic rod 31 is installed on one side of the support plate 5, a rectangular seat 32 is rotatably installed on the output rod of the second electric telescopic rod 31, and the rectangular seat 32 is slidably connected to the output rod of the connecting plate 30.

[0053] In this embodiment, when the active roller 6 needs to be replaced, the second electric telescopic rod 31 is first started, so that the output rod of the second electric telescopic rod 31 drives the rectangular seat 32 to slide, so that the rectangular seat 32 slides away from the output rod of the connecting plate 30, and then the active roller 6 can be removed from the connecting seat and the rectangular seat 32 for replacement. The operation is relatively quick. Through the telescopic movement of the second electric telescopic rod 31, the active roller 6 can be easily loaded and unloaded, thereby improving the replacement efficiency.

[0054] In a further preferred embodiment of the present invention, the output rods of the active roller 6 and the connecting plate 30 are both arranged in a rectangular shape, a support wheel 39 is installed on a group of the support plates 5, and the support wheel 39 is in rotational contact with the active roller 6 located below, and the output rod of the active roller 6 is arranged in a rectangular shape.

[0055] In this embodiment, the output rods of the active roller 6 and the connecting plate 30 are both rectangular, making the connection between them more stable and reliable, because the rectangular structure is not easy to rotate or deflect when subjected to force. At the same time, the rectangular output rod is also convenient for sliding connection with components such as the rectangular seat 32, and the design of the support wheel 39 provides additional support for the active roller 6, which helps to maintain the stability and balance of the active roller 6 during the transmission process.

[0056] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0057] In another embodiment of the present invention, a connecting groove is provided on one side of the active roller 6, and a rubber tube 33 is sleeved on the active roller 6. A clamping rod 34 is fixedly installed on one side of the inner wall of the rubber tube 33, and the clamping rod 34 is slidably connected to the connecting groove. Both sides of the rubber tube 33 are in contact with the baffle and the connecting plate 30 of the active roller 6 respectively.

[0058] In this embodiment, the rubber tube 33 serves as a protective layer for the active roller 6, which can significantly reduce the direct friction and wear between the wire rope and the active roller 6, thereby extending the service life of the wire rope. The elasticity of the rubber tube 33 can also absorb the vibration and impact generated during the transmission process, thereby reducing the noise level of the system and improving the comfort of the working environment. The setting of the clamping rod 34 ensures that the rubber tube 33 can be stably fixed on the active roller 6 to prevent it from falling off or shifting during the transmission process. When the rubber tube 33 is worn to a certain extent, it can be easily removed from the active roller 6 and replaced with a new rubber tube 33, thereby simplifying the maintenance work of the system.

[0059] In another embodiment of the present invention, a connecting block 35 is fixedly installed on one side of the connecting plate 30, a sliding groove is provided at one end of the active roller 6, and the connecting block 35 is slidably connected to the sliding groove. A mounting groove is provided in the active roller 6, and a connecting spring 36 is fixedly installed on the top of the inner wall of the mounting groove. A clamping block 37 is fixedly installed on the bottom end of the connecting spring 36, and the clamping block 37 slides and extends into the sliding groove and contacts with the clamping groove of the connecting block 35. An L-shaped groove is provided on one side of the active roller 6, and the L-shaped groove is connected to the mounting groove. A pull rope 38 is installed on the top of the clamping block 37, and one end of the pull rope 38 extends out of the active roller 6 through the L-shaped groove.

[0060] In this embodiment, when the connecting block 35 completely slides into the slide groove, the block 37 will slide and extend into the slide groove and contact the slot on the connecting block 35. This contact mode ensures a stable connection between the connecting plate 30 and the active roller 6. A connecting piece is installed at one end of the pull rope 38, and the connecting piece slides through the connecting plate 30. When the connecting plate 30 needs to be disassembled, the connecting piece can be pulled, thereby pulling the pull rope 38, so that the block 37 rises and disengages from the slot, thereby realizing the separation of the connecting plate 30 and the active roller 6. The disassembly efficiency is high. The sliding connection and the contact between the card block 37 and the card slot realize a stable connection between the connecting plate 30 and the active roller 6. This connection method can withstand greater forces and ensure that it will not loosen due to vibration or impact during transmission. The design of the L-shaped groove and the pull rope 38 makes it easy to remove the connecting plate 30 when necessary, thereby simplifying the maintenance process and improving work efficiency. Since the connecting block 35 and the slide slot are slidably connected, and the card block 37 can automatically reset under the action of the connecting spring 36, the wear caused by frequent disassembly and installation is reduced.

[0061] In summary, compared with the related art, the device has the advantage of greatly reducing the friction coefficient and the degree of wear, and significantly extending the service life of the wire rope, by causing rolling friction between the wire rope and the first horizontal roller 4, the active roller 6 and the limiting mechanism when the wire rope slides.

[0062] In the several embodiments provided in this application, it should be understood that the disclosed device can be implemented in other ways.
