Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ship winches, in particular to a guided self-cleaning ship winch. BACKGROUND

[0002] A ship winch is an important mechanical device used for winding and unwinding cables, anchor chains, cargo or equipment on a ship, and is widely used in berthing, anchoring, cargo handling and ship towing operations. Its performance directly affects the safety and efficiency of ship operations, and is usually composed of a power device (such as a motor, a hydraulic motor), a transmission system, a drum, a brake, a clutch and a control system. The force is transmitted and controlled: the cable / anchor chain is wound around the drum to provide traction or lifting force, precise positioning: the brake and clutch are used to start and stop the drum and control its speed, safety protection: overload protection, emergency brake and other devices are provided to ensure safety during operation.

[0003] Through retrieval, Chinese patent publication No. CN 209127940 U discloses a ship winch, which comprises a winding shaft and two supports, the bottom of each of the two supports is movably installed with a base, the upper part of each of the two supports is rotatably installed with a mounting block, the center of each of the two mounting blocks is installed with a first bearing, the two ends of the winding shaft are respectively sleeved with the two first bearings, the winding baffle is circumferentially provided with a clamping groove, a slide rod is arranged between the two supports and close to the lower side of the two winding baffles, limit blocks are installed at the two ends of the slide rod, locking bolts are installed on the upper part of the side wall of each of the two supports, connecting rods are installed on the locking bolts, second bearings are fixedly installed at one end of each of the two connecting rods, the two ends of the slide rod are respectively inserted into the two second bearings, and the two second connecting pieces are connected through a connecting mechanism. The present application has the advantages of simple structure, convenient adjustment, convenient use, strong applicability, ability to ensure neat winding and convenience in use.

[0004] For the related technology in the above, the inventors found that the existing ship winch has the following defects: when the ship winch is in use, the cable cannot clean the surface-attached impurities in time and effectively, which leads to the accumulation of impurities, causing mechanical failure, accelerating the wear of gears and chains, resulting in transmission noise and reduced efficiency, and in severe cases, the clutch or brake may be stuck, causing the winch to fail to start and stop normally. Mud and oil stains adhere to the surface of the drum or the gap of the cable, which damages the friction of the drum's anti-slip pattern or causes the cable dispenser to jam. In the ship operation 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 the metal parts such as the drum, the frame and the gears will rust and have pitting, resulting in a decrease in strength. When there is no self-cleaning function, the winch parts (such as the gear box and the brake) need to be disassembled regularly for cleaning, which is time-consuming and labor-intensive. During the cleaning and maintenance period, the winch cannot be operated, which affects the efficiency of ship berthing and cargo handling. SUMMARY

A groove is provided at the top right end of the winch box 9, and a winch disc 11 is fitted into 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 winch disc. The second pulley 5 is located above the middle of the first pulley 3 and the third pulley 8. The second pulley 5 is connected to a belt 4 for transmission. All three pulleys can rotate simultaneously under the action of the belt 4, allowing the first rotating shaft 2 at one end of the winch disc 11 to rotate simultaneously. An anti-slip layer is provided in the middle of the winch disc 11 to increase friction between the anchor chain and the winch disc 11, preventing the anchor chain from falling off.

[0033] The implementation principle of the guided self-cleaning ship winch is as follows: when the ship anchor chain is wound, the anchor chain is wound on the surface of the winch disc 11 through the cleaning water ring 15, the limiting ring 22 and the cleaning ring 26, one end of the anchor chain is hung on the surface of the hook 10, the motor 7 is started as a power source to drive the winch disc 11 to rotate, and the effect of winding the anchor chain is realized; when the anchor chain is wound, the liquid pump 14 is started to spray the liquid in the inside to the surface of the anchor chain at high speed through the cleaning water ring 15 and the nozzle on the surface, so that the sea salt crystals, biological attachments (mussels / algae), oil stains, silt and other stubborn impurities on the surface of the anchor chain are effectively stripped, the cavitation effect (microscopic bubbles generated by high-speed water flow are broken) generated by the water flow is deep into the gap, 360° cleaning without dead angle is realized, the gap at the chain ring connection is easy to accumulate impurities, the water flow can remove the residual particles in the gap through kinetic impact, and local corrosion (such as pitting and crevice corrosion) caused by impurity retention is avoided.

[0034] After the anchor chain is washed by the water flow, the high-speed airflow generated by the air blowing fan 12 blows to the surface of the anchor chain through the cleaning ring 26, the residual moisture (especially the salt-containing seawater) on the surface of the cleaned anchor chain will form an electrolyte solution, which is easy to cause electrochemical corrosion when contacting with the metal surface, the wind drying can quickly remove the surface moisture, reduce the water retention time, and inhibit the occurrence of corrosion reaction from the root, the wet anchor chain is easy to become the attachment carrier of mussels, algae and other marine microorganisms when being stored in water or on the deck, the surface of the dried anchor chain is dry, the initial attachment of microorganisms is reduced, especially for the ship that is long-term parked or works in eutrophic water, the dry anchor chain surface is more suitable for brushing anticorrosive grease (such as anchor chain oil) or antirust paint, the paint coating is more firmly combined with the metal, problems such as air bubbles and peeling are reduced, and the protection period is prolonged.

[0035] When the motor 7 drives the capstan disc 11 to rotate, the first rotating shaft 2 rotates through the belt strip 4, the first rotating shaft 2 drives the eccentric wheel 30 to rotate through the bevel gear, the eccentric wheel 30 drives the vertical plate 19 to move left and right through the rotating rod 34 on one side, the vertical plate 19 drives the I-shaped slide plate 23 and the limiting ring 22 above to move, so that the anchor chain can move left and right when being wound up, and the anchor chain can be evenly wound on the surface of the capstan disc 11, so that the anchor chain is not cross-wound, and subsequent use is facilitated.

[0036] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
