Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] The following describes an embodiment of this utility model based on its overall structure.

[0021] like Figures 1 to 5As shown, the present invention provides a marine retractable mooring winch, including a mounting base 1. The bottom of the mounting base 1 is provided with an adjustment component 2. The adjustment component 2 includes a base 201. A first motor 202 is fixedly mounted on the rear side of the base 201. A screw 203 is fixedly mounted at the end of the main shaft of the first motor 202. A first connecting block 204 is spirally sleeved on the outer side of the screw 203. Sliding columns 206 are fixedly mounted on both the left and right sides inside the base 201. A second connecting block 207 is slidably sleeved on the outer side of the sliding columns 206. Through the extension and retraction adjustment driven by the motor, the screw drive and the guide of the sliding columns 206 on both sides, the automatic and stable adjustment of the position of the winch structure is realized, which can adapt to the needs of cable winding and unwinding position adjustment in scenarios such as changes in draft, differences in berthing dock height, and hull swaying.

[0022] In this embodiment, a first limiting seat 205 is fixedly provided inside the base 201. The first limiting seat 205 is slidably connected to the first connecting block 204. A second limiting seat 208 is fixedly provided on both the left and right sides inside the base 201. The second limiting seat 208 is slidably connected to the second connecting block 207. The first connecting block 204 and the second connecting block 207 are fixedly connected to the mounting base 1. The setting of the first limiting seat 205 and the second limiting seat 208 precisely limits the sliding trajectory of the first connecting block 204 and the second connecting block 207, preventing deviation and avoiding jamming or deviation problems when the adjustment component 2 is running, thereby improving the smoothness and accuracy of the telescopic adjustment.

[0023] The top of the mounting base 1 is provided with a cable winch assembly 3, which includes a second motor 301. A reducer 302 is fixedly provided at the output end of the second motor 301, and a cable winch shaft 303 is provided at the output end of the reducer 302. This meets the high tensile strength requirements of marine cable winding and unwinding, and is suitable for heavy-load operation scenarios when ships are moored. A cable winch roller 304 is fixedly sleeved on the outside of the cable winch shaft 303. A bracket 306 is fixedly provided on the left side of the top of the mounting base 1. The left side of the cable winch shaft 303 is rotatably connected to the bracket 306 to ensure the stability of the rotation of the cable winch roller 304.

[0024] Both sides of the cable winch 304 are fixedly provided with baffles 305. The top right side of the baffle 305 is fixedly provided with a positioning block 307. The positioning block 307 is slidably provided with a fixing groove plate 308. The front and rear sides of the fixing groove plate 308 are slidably provided with limit rods 309. The top right side of the cable winch 304 is provided with an adjusting stud 310 that spirals through the middle of the fixing groove plate 308. This can adapt to marine cables of different thicknesses and specifications, and at the same time prevent the cable from slipping out from both sides of the cable winch 304 during winch operation, thus improving the safety of winch operation.

[0025] The cable winch 304 has a spiral cable groove on its outer side and an anti-slip rubber pad on its inner wall. The anti-slip rubber pad has a diamond-shaped anti-slip pattern on its surface, which increases the friction between the cable and the cable winch 304, prevents cable slippage during winch, and ensures the reliability of winch operation under heavy load and high tension.

[0026] The top of the bracket 306 is provided with a guide assembly 4. The guide assembly 4 includes a fixed seat 401 that is fixedly mounted on the top of the bracket 306 and the reducer 302. The fixed seat 401 has a sliding groove 402 on both the front and rear sides. A gas spring 403 is fixedly mounted inside the sliding groove 402. A slider 404 is fixedly mounted on one end of the gas spring 403. A guide shaft 405 is fixedly mounted on the bottom of the slider 404. A guide roller 406 is rotatably mounted on the outside of the guide shaft 405. This provides professional guidance for the cable winding and unwinding, changes the force angle of the cable, and adapts to the scenario of hull swaying and cable tension fluctuation when the ship is moored. It also adapts to the tension requirements of cables of different diameters, further improving the stability of cable winding and unwinding.

[0027] The motor and reducer are existing technologies and will not be described in detail. The wiring diagram of the motor in this invention is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use, so the control method and wiring layout of the motor will not be explained in detail.

[0028] Working principle and process of a marine retractable mooring winch: Based on the ship's draft and the position of the mooring bollards, the first motor 202 is started. The main shaft of the first motor 202 drives the screw 203 to rotate. Since the first connecting block 204 is screwed to the screw 203 and its rotation trajectory is limited by the first limiting seat 205, the first connecting block 204 makes a linear displacement along the screw 203. At the same time, the mounting seat 1 drives the second connecting block 207 to slide synchronously along the sliding column 206. The second limiting seat 208 ensures that the displacement of the second connecting block 207 is accurate and does not deviate. One end of the marine cable is passed between the guide roller 406 and the winnowing roller 304. The tension of the cable itself acts on the guide roller 406, causing the guide shaft 405 and the slider 404 to slide along the groove 402 of the fixed seat 401. The gas spring 403 adapts to the tension and extends and retracts, adjusting the position and angle of the guide roller 406 so that the cable always maintains a reasonable force angle. One end of the cable is wound into the spiral cable groove of the winnowing roller 304. The adjusting stud 310 is rotated to push the fixed groove plate 308 to slide along the positioning block 307. With the help of the limit rod 309, the fixed groove plate 308 is precisely positioned so that the fixed groove plate 308 presses the end of the cable to prevent the cable from slipping and falling off during operation. The diamond pattern of the anti-slip rubber pad on the inner wall of the winnowing roller 304 further enhances the friction between the cable and the roller. The second motor 301 is started, and the power is transmitted to the cable winch shaft 303 after being reduced in speed and increased in torque by the reducer 302. This drives the cable winch roller 304 to rotate. When the cable is being wound up, the cable winch roller 304 guides the cable to wind in an orderly manner through the spiral cable groove. The left and right baffles 305 prevent the cable from slipping out from both sides of the roller. When the cable is being released, the second motor 301 rotates in the opposite direction. Under the action of the ship's inertia or external force, the cable is released at a uniform speed along the spiral groove. The guide roller 406 continuously and adaptively adjusts with the change of cable tension to buffer the impact of tension.
