[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Specific implementation examples are given below.
[0024] Please see Figures 1-4 This utility model provides a marine hydraulic winch, including a fixed plate 1. The fixed plate 1 has a rotating shaft 2 fixedly installed in the middle. A groove 3 is provided on the fixed plate 1 and on the outer side of the rotating shaft 2. A ball bearing 4 is fitted on the inner side of the groove 3. A rotating plate 12 is fixedly installed on the top of the rotating shaft 2. A bearing 5 is provided on the fixed plate 1 and on the outer side of the rotating plate 12. A handle connecting rod 10 is fixedly installed on the bearing 5. A second gear 11 is fixedly installed on the handle connecting rod 10. A fixed frame 15 is fixedly installed on the top of the rotating plate 12. A hydraulic winch body 16 is fixedly installed on the top of the fixed frame 15. A guide mechanism is provided on the hydraulic winch body 16.
[0025] During operation, the system includes a fixed plate 1 for loading onto the hull, a rotating shaft 2 fixedly mounted in the middle of the fixed plate 1 to support the fixed plate 1 and the rotating plate 12, and the rotating plate 12 can rotate on the fixed plate 1 via the rotating shaft 2. A groove 3 on the fixed plate 1, located on the outer side of the rotating shaft 2, is used to load ball bearings 4, which can roll circumferentially inside the groove 3. The ball bearings 4, with clearance fit inside the groove 3, provide sliding support for the rotating plate 12 on top of the fixed plate 1, ensuring sufficient stability during use. The rotating plate 12, fixedly mounted on top of the rotating shaft 2, drives the hydraulic winch body 16 to rotate during operation. A bearing 5 on the fixed plate 1, located on the outer side of the rotating plate 12, supports the handle connecting rod 10, allowing the handle connecting rod 10 to... The hydraulic winch body 16 can rotate smoothly on the fixed plate 1. The handle connecting rod 10 fixed on the bearing 5 drives the second gear 11 to rotate, and the second gear 11 drives the rotating plate 12 to rotate, so that the hydraulic winch body 16 can rotate flexibly during use, improving the efficiency of steel rope winding and unwinding on the hydraulic winch body 16. The fixed frame 15 fixed on the top of the rotating plate 12 is used to load the hydraulic winch body 16, so that the hydraulic winch body 16 and the rotating plate 12 maintain a stable connection. The hydraulic winch body 16 fixed on the top of the fixed frame 15 is used to wind and unwind the steel rope. The guide mechanism set on the hydraulic winch body 16 can make the steel rope wound more orderly during the winding and unwinding process. The steel rope is a mature existing technology and will not be described in detail in this article.
[0026] Furthermore, such as Figure 4 As shown, a first gear 6 is rotatably mounted on the fixed disk 1 and located outside the rotating disk 12. A straight groove 7 is provided on the first gear 6, which penetrates the fixed disk 1. A plug-in block 8 is inserted into the inner side of the straight groove 7.
[0027] During operation, the first gear 6, which is rotatably mounted on the fixed disk 1 and located outside the rotating disk 12, is used to load the plug-in block 8 through the straight groove 7 opened on the first gear 6. After the plug-in block 8, which is inserted into the straight groove 7, is inserted into the fixed disk 1 and the first gear 6, the first gear 6 is also meshed with the annular groove 13. This prevents the first gear 6 from rotating after the plug-in block 8 is inserted into the straight groove 7, thereby restricting the rotation of the rotating disk 12. This system is used when the hydraulic winch body 16 is not in use.
[0028] Furthermore, such as Figure 1 As shown, an annular groove 13 is provided on the inner side of the rotating disk 12, and teeth 14 are provided on the inner side of the annular groove 13. The second gear 11 meshes with the teeth 14.
[0029] During operation, the annular groove 13 on the inner side of the rotating disk 12 serves as an extension for the first gear 6 and the second gear 11. The teeth 14 on the inner side of the annular groove 13 control the rotation or non-rotation of the rotating disk 12. When rotating, the second gear 11 is driven to rotate via the handle connecting rod 10, which in turn drives the rotating disk 12 to rotate. The rotating disk 12 then drives the hydraulic winch body 16 to rotate, allowing the hydraulic winch body 16 to wind and unwind steel ropes at multiple angles. When rotation is not required, the rotation of the rotating disk 12 is restricted by the connection between the plug block 8 and the first gear 6 and the fixed disk 1, thus ensuring the stability of the hydraulic winch body 16 when not in use.
[0030] Furthermore, such as Figure 1 As shown, a loading seat 9 is fixedly installed on the fixed plate 1 and near the second gear 11, and the handle connecting rod 10 passes through the inner side of the loading seat 9;
[0031] During operation, the loading seat 9, which is fixedly installed on the fixed plate 1 and near the second gear 11, is used to limit the handle connecting rod 10 so that the handle connecting rod 10 remains stable when rotating.
[0032] Furthermore, such as Figure 1 As shown, the guiding mechanism includes a receiving seat 17 fixedly installed on the hydraulic winch body 16. A slide rod 18 and a lead rod 19 are arranged sequentially on the receiving seat 17. The lead rod 19 is located inside the two slide rods 18. A slide block 20 is sleeved on the lead rod 19 and the slide rods 18. A motor 22 is fixedly installed on the outside of the receiving seat 17. The output end of the motor 22 is connected to the lead rod 19.
[0033] During operation, the receiving seat 17 fixedly installed on the hydraulic winch body 16 is used to load the slide rod 18 and the lead screw 19. The slide rod 18 is used to limit the slide block 20, so that it remains stable during lateral movement. The lead screw 19 is used to guide and control the lateral movement of the slide block 20. Specifically, by starting the motor 22, the motor 22 drives the lead screw 19 to rotate, and the lead screw 19 drives the slide block 20 to move laterally, so that the hydraulic winch body 16 can be more orderly in the process of winding and unwinding steel rope.
[0034] Furthermore, such as Figure 1 As shown, a guide sleeve 21 is fixedly provided on the top of the slide 20;
[0035] During operation, the slide 20 is used to load the guide sleeve 21, and the guide sleeve 21, which is fixedly installed on the top of the slide 20, is used to limit the steel rope. In use, the steel rope is threaded through the inside of the guide sleeve 21.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
