Description

Technical Field

[0001] The present invention relates to the technical field of ship winches, and in particular to a guided self-cleaning ship winch. Background Art

[0002] A ship winch is a crucial mechanical device used on ships for retracting and releasing cables, anchor chains, cargo, or equipment. It is widely used in operations such as berthing, anchoring, cargo loading and unloading, and towing. Its performance directly impacts the safety and efficiency of ship operations. It typically consists of a power unit (such as an electric motor or hydraulic motor), a transmission system, a drum, brakes, a clutch, and a control system. Force transmission and control: The drum winds the cable / anchor chain, providing traction or lifting force. Precise positioning: The drum is started, stopped, and speed controlled using brakes and clutches. Safety: Overload protection and emergency braking devices ensure safe operations.

[0003] Through search, Chinese patent publication No. CN 209127940 U discloses a ship winch, including a stranding shaft and two brackets, the bottom of the two brackets are movably installed with a base, the upper parts of the two brackets are rotatably installed with a mounting block, the centers of the two mounting blocks are installed with a first bearing, the two first bearings are respectively sleeved on the two ends of the stranding shaft, the winding baffle is circumferentially provided with a slot, a sliding rod is provided between the two brackets near the lower side of the two winding baffles, limiting blocks are installed at both ends of the sliding rod, locking bolts are installed on the upper parts of the side walls of the two brackets, and a connecting rod is installed on the locking bolt, and one end of the two connecting rods is fixedly installed with a second bearing, the two ends of the sliding rod are respectively inserted in the two second bearings, and the two second connecting members are connected by a connecting mechanism. The present invention has a simple structure, is easy to adjust, convenient to use, has strong applicability, can ensure neat winding, and is easy to use.

[0004] In response to the above-mentioned related technologies, the inventors found the following defects: when the existing ship winch is in use, the cable cannot clean the impurities attached to the surface in a timely and effective manner, resulting in mechanical failure caused by the accumulation of impurities, accelerated wear of gears and chains, resulting in abnormal transmission noise and reduced efficiency. In severe cases, the clutch or brake may be stuck, causing the winch to be unable to start and stop normally. Mud and oil adhere to the surface of the drum or in the gaps of the cable, destroying the friction of the anti-slip grooves of the drum, or causing the rope arranger to jam. In the ship's operating environment, seawater salt spray and humid air are easy to come into contact with the metal surface. If impurities (such as salt-containing mud) adhere for a long time, an electrochemical corrosion environment will be formed, and metal parts such as the drum, frame, and gears will rust and pit, and their strength will decrease. When there is no self-cleaning function, the winch components (such as gearboxes and brakes) need to be manually disassembled and cleaned regularly, which is time-consuming and labor-intensive. The winch cannot operate during cleaning and maintenance, affecting the efficiency of ship berthing and loading and unloading. Summary of the Invention

Detailed implementation manners

[0020] The following will Figure 1-6 make a further detailed description of the present invention.

[0021] The embodiment of the present invention discloses a self-guided cleaning ship winch. As Figure 1 shown, it includes a base frame 1. A winch box 9 is fixedly arranged on the top of the base frame 1. There is a groove at the top position of the right end of the winch box 9, and a winch wheel disc 11 is clamped and arranged at the bottom of its inner wall. A second pulley 5 is fixedly sleeved on the outer side of the rotating shaft in the middle of the dragon reel. The second pulley 5 is located above the middle of the first pulley 3 and the third pulley 8. The second pulley 5 is in transmission connection with the belt strip 4. Under the action of the belt strip 4, the three pulleys can rotate simultaneously, so that while the winch wheel disc 11 rotates, the first rotating shaft 2 at one end can rotate simultaneously. A non-slip layer is arranged in the middle of the winch wheel disc 11. The arrangement of the non-slip layer increases the friction between the anchor chain and the winch wheel disc 11, avoiding the falling of the anchor chain. Hooks 10 are arranged on both sides of the winch wheel disc 11. The hooks 10 are convenient for hanging one end of the anchor chain. The central position of the winch wheel disc 11 is collinear with the center of the limiting circular ring 22. The collinear arrangement of the limiting circular ring 22 and the winch wheel disc 11 makes it more convenient to pass the anchor chain through.

[0022] Please refer to Figure 2 and Figure 3, a middle support plate 16 is fixedly arranged in the middle of the inner wall of the winch box 9. A chute is fixedly arranged in the middle of the middle support plate 16, and an I-shaped sliding plate 23 is slidably arranged on its inner wall. A limiting ring 22 is fixedly arranged at the top of the I-shaped sliding plate 23 through a connecting plate. A round rod is fixedly arranged on the inner wall of the limiting ring 22 through a connecting rod. A pulley ball 29 is sleeved on the outer circumferential surface of the round rod. The outer side of the pulley ball 29 extends out of the inner ring edge of the limiting ring 22. Two symmetrical inner rods are fixedly arranged on the outer side of the limiting ring 22. One ends of the two inner rods away from the limiting ring 22 are slidably inserted into the inner wall of the sleeve 24. One end of the sleeve 24 is fixedly arranged on both sides of the inner wall of the winch box 9. When the anchor chain passes through the limiting ring 22, by contacting the pulley ball 29 at the edge position, the sliding of the anchor chain is smoother, preventing the phenomenon of jamming. The limiting ring 22 moves along with the I-shaped sliding plate 23 and moves more stably through the two sleeves 24 on both sides.

[0023] Please refer to Figure 2 , a top vertical plate 25 is fixedly arranged at the top of the limiting ring 22. A liquid pump 14 is fixedly arranged at the top of the top vertical plate 25. A cleaning water ring 15 is fixedly arranged at the middle position of the top of the liquid pump 14 through a pipeline and is communicated with its top. Nozzles are evenly arranged on the outer side of the cleaning water ring 15. The nozzles are arranged at an angle less than 90 degrees. The cleaning water ring 15 is concentric with the limiting ring 22. The nozzles evenly spray the cleaning water source inside the cleaning water ring 15 on the surface of the anchor chain, effectively peeling off stubborn impurities such as sea salt crystals, biological attachments (barnacles / algae), oil stains, and sediment on the surface of the anchor chain. The water flow can penetrate into the gaps through the cavitation effect (the rupture of tiny bubbles generated by high-speed water flow), realizing 360° dead-angle-free cleaning. A fixed ring plate 21 is fixedly arranged on the outer side of the cleaning water ring 15 through a connecting rod. One side of the fixed ring plate 21 away from the cleaning water ring 15 is fixedly connected to one side of the limiting ring 22.

[0024] Please refer to Figure 3 and Figure 4The bottom of the I-shaped slide 23 is fixed with a vertical plate 19, and the bottom of the vertical plate 19 is fixed with a slider 20. The middle of the slider 20 is slidably plugged with a horizontal shaft 17. The two ends of the horizontal shaft 17 are fixed to the inner wall of the winch box 9. Two identical limiting circular shafts are fixed in the middle of both sides of the vertical plate 19. The outer side of the middle of the limiting circular shaft is slidably sleeved with an arc-shaped support rod 18. The bottom of the arc-shaped support rod 18 is fixed to the bottom of the inner wall of the winch box 9. The slider 20 slides on the surface of the horizontal shaft 17 by the tension of the upper vertical plate 19 to ensure the stability of the vertical plate 19 when it moves left and right. A rotating rod 34 is slidably provided on the inner wall of the slide groove in the middle of the vertical plate 19. An eccentric The first bevel gear 32 is fixedly provided on the middle part of one side of the eccentric wheel 30 through a rotating rod, and the first bevel gear 32 is provided with a second bevel gear 33 through the tooth meshing on one side of the outer circumference. The middle part of the second bevel gear 33 is fixedly plugged with the first rotating shaft 2, and the middle part of the first rotating shaft 2 is rotatably provided with a first limiting vertical plate 31. The bottom of the first limiting vertical plate 31 is fixedly provided on the bottom of the inner wall of the winch box 9, and the middle part of the rotating rod on one side of the first bevel gear 32 is rotatably provided with a second limiting vertical plate 28. The bottom of the second limiting vertical plate 28 is fixedly provided on the bottom of the inner wall of the winch box 9. The first limiting vertical plate 31 and the second limiting vertical plate 28 are used to ensure that the first bevel gear 32 and the second bevel gear 33 can rotate stably.

[0025] See also Figure 1 and Figure 4 One end of the first rotating shaft 2 away from the second bevel gear 33 extends to the outside of the winch box 9 and is fixedly sleeved with a first pulley 3. The middle part of the outer circumference of the first pulley 3 is transmitted by a belt strip 4 to a third pulley 8. The middle part of the third pulley 8 is fixedly plugged with the output shaft of the motor 7. A support plate 6 is fixedly provided at the bottom of the motor 7, and one end of the support plate 6 is fixedly provided at the bottom of one side of the winch box 9.

[0026] See also Figure 3, a cross - plate 27 is fixedly arranged at the top of one side of the top vertical plate 25. Two identical telescopic slide rods 13 are fixedly arranged on both sides of the cross - plate 27. One end of the telescopic slide rod 13 far from the cross - plate 27 is fixedly arranged on both sides of the inner wall of the winch box 9. Air outlet holes are evenly arranged on the inner wall of the cleaning ring 26 at the bottom of the cross - plate 27. The blowing fan 12 at the top of the cross - plate 27 moves along with the top vertical plate 25. Under the action of the two telescopic slide rods 13 on both sides, tilting during movement is avoided. Through the air outlet holes on the inner wall of the cleaning ring 26, air is evenly blown on the surface of the anchor chain, realizing the drying of the anchor chain. The drying operation can destroy the humid environment for bacteria survival, reducing the risk of biological corrosion. When the anchor chain is in an emergency anchoring or weighing anchor, the dry anchor chain has less running resistance and higher winding and unwinding efficiency, which can shorten the ship's emergency response time. The blowing fan 12 is fixedly arranged at the top of the cross - plate 27. The bottom of the blowing fan 12 is connected to the cleaning ring 26 through a pipeline. The top of the cleaning ring 26 is fixedly connected to the bottom of the cross - plate 27.

[0027] The implementation principle of a self - guiding and self - cleaning ship winch in an embodiment of the present invention is as follows: When winding the ship's anchor chain, the anchor chain passes through the cleaning water ring 15, the limiting ring 22 and the cleaning ring 26 and winds around the surface of the winch disc 11. One end of the anchor chain is hung on the surface of the hook 10. By starting the motor 7 as the power to drive the winch disc 11 to rotate, the effect of taking in the anchor chain is achieved. When the anchor chain is being taken in, the liquid pump 14 is started to spray the liquid inside at a high speed through the cleaning water ring 15 and the nozzles on its surface onto the surface of the anchor chain, effectively peeling off stubborn impurities such as sea salt crystals, biological attachments (barnacles / algae), oil stains, and sediment on the surface of the anchor chain. Through the cavitation effect generated by the water flow (the rupture of tiny bubbles generated by high - speed water flow), it penetrates into the gaps, realizing 360° dead - angle - free cleaning. The gaps at the chain links are prone to accumulating impurities, and the water flow can remove the residual particles in the gaps through kinetic energy impact, avoiding local corrosion (such as pitting corrosion and crevice corrosion) caused by the retention of impurities. After the anchor chain is rinsed by water flow and passes through the cleaning ring 26, the high - speed air flow generated by the blowing fan 12 is blown onto the surface of the anchor chain through the cleaning ring 26. The residual water (especially seawater containing salt) on the surface of the cleaned anchor chain will form an electrolyte solution, which is prone to causing electrochemical corrosion when contacting the metal surface. Drying by wind can quickly remove the surface water, reducing the water retention time and inhibiting the occurrence of corrosion reactions from the root cause. When the wet anchor chain is stored in water or on the deck, it is prone to becoming an attachment carrier for marine microorganisms such as barnacles and algae. The surface of the dried anchor chain is dry, which can reduce the breeding ground for the initial attachment of microorganisms, especially having a significant effect on ships that are berthed for a long time or operating in eutrophic waters. The dry surface of the anchor chain is more suitable for applying anti - corrosion grease (such as anchor chain oil) or anti - rust paint. The paint coating combines more firmly with the metal, reducing problems such as bubbles and peeling, and extending the protection period. When the motor 7 drives the winch disc 11 to rotate, the first rotating shaft 2 rotates simultaneously through the belt strip 4. The first rotating shaft 2 drives the eccentric wheel 30 to rotate through the cooperation of bevel gears. When the eccentric wheel 30 rotates, the vertical plate 19 can move left and right through the rotating rod 34 on one side. The vertical plate 19 drives the upper I-shaped slide plate 23 and the limiting ring 22 to move simultaneously, enabling the anchor chain to move left and right when being retracted, ensuring that it can be evenly wound on the surface of the winch disc 11, avoiding the anchor chain from being intertwined, and facilitating subsequent use.

[0028] The above are all preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
