Technical Field

[0001] The utility model relates to the technical field of capstan winches, in particular to a marine capstan winch with a limiting structure. Background Technique

[0002] The capstan winch, also known as an anchor windlass, is a large deck machinery on a ship, used for retrieving and paying out the anchor and anchor chain. It is usually installed on the main deck at the bow and stern of the ship and is used when the ship anchors, drops the anchor, and moors. It is an important part of the ship equipment.

[0003] For example, the patent authorization announcement number CN207536101U, the authorization announcement date is June 26, 2018, discloses a new type of marine anchor windlass, including a bottom plate, a second gear, a fourth gear, a guide plate and a limiting plate. A fixed base is arranged on the left front end of the bottom plate, a connecting hole is arranged below the fixed base, a main body shell is arranged on the right side of the motor, a third gear is connected to the right side of the second gear, a rotating shaft is arranged inside the fourth gear, a fixing nut is installed at the left end of the rotating shaft, a sixth gear is connected above the fifth gear, and a cross-shaped buckle handle is arranged on the right side of the guide plate. Compared with the existing ordinary anchor windlass, this new type of marine anchor windlass increases the structure and greatly improves the functionality of the whole device. Through two motors and more gear transmissions, the whole device is used more quickly and effectively, and the lifting of the ship anchor is controlled by two ropes, avoiding wear on the rope body and the hull during use, thereby improving the service life.

[0004] However, in the prior art, there is a lack of a limiting mechanism when the anchor sprocket is stationary, there is a risk of rotation, and the size of the usually used anchor sprocket is fixed, which is not convenient to adjust the size of the anchor chain according to the amount of the anchor chain. For example, the above-listed comparative patent has this problem.

[0005] Therefore, we propose a marine capstan winch with a limiting structure to solve the above problems. Content of the Utility Model

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] Please refer to Figures 1-7 , the present utility model provides the following technical solutions.

[0033] Embodiment 1: To solve the problems existing in the prior art, therefore, in this embodiment, through the following technical solutions, a marine anchor winch with a limiting structure, as Figure 1 and Figure 2 shown, is provided with a base 1, a left support plate 2, a right support plate 3, a reduction motor 4 and an anchor sprocket 5. The left end of the base 1 is welded with the left support plate 2, the right end of the base 1 is welded with the right support plate 3, the upper end of the left support plate 2 is fixedly installed with the reduction motor 4, and the output end of the reduction motor 4 is fixedly connected with the anchor sprocket 5. The anchor chain is wound around the outside of the anchor sprocket 5. Start the reduction motor 4 installed at the upper end of the left support plate 2, and the reduction motor 4 drives the anchor sprocket 5 to slowly rotate at the upper ends of the left support plate 2 and the right support plate 3, thereby performing a winding operation on the anchor chain.

[0034] Embodiment 2: The existing marine anchor winch is not convenient to adjust the size of the anchor chain according to the amount of the anchor chain. Therefore, by providing an adjustment mechanism 6 and a fixing groove 10, as Figure 3 and Figure 4 shown, the adjustment mechanism 6 includes adjustment plates 7 inserted on the left and right sides of the anchor sprocket 5, movable rods 8 fixedly connected to the outer sides of the adjustment plates 7, and fixing caps 9 for limiting. A structure is formed between the adjustment plate 7 and the anchor sprocket 5, and a sliding structure is formed between the anchor sprocket 5 and the movable rod 8. The movable rod 8 and the fixing cap 9 are connected by a threaded manner. By pulling the adjustment plate 7, the adjustment plate 7 slides between the adjustment plate 7 and the anchor sprocket 5, and the adjustment plate 7 drives the movable rod 8 to slide between the adjustment plate 7 and the anchor sprocket 5. The adjustment plate 7 is pulled out from the anchor sprocket 5, and the adjustment plate 7 and the anchor sprocket 5 are pulled from the state as Figure 1 shown to the state as Figure 3 shown. Then, rotate the fixing cap 9 threadedly connected to the outer surface of the movable rod 8, and the fixing cap 9 is engaged in the fixing groove 10, thereby facilitating the limitation between the movable rod 8 and the anchor sprocket 5, and thus facilitating the fixation between the adjustment plate 7 and the anchor sprocket 5. Through the setting of the adjustment plate 7, when the anchor chain cannot be wound up, the actual size of the anchor sprocket 5 can be increased to achieve the winding effect of more anchor chains, and the practicability is high.

[0035] Embodiment 3: For the existing marine capstan, there is a lack of a limiting mechanism for the anchor sprocket 5 when it is stationary, which poses a risk of rotation. Moreover, the size of the commonly used anchor sprocket 5 is fixed. Therefore, by setting a limiting disc 11, a limiting groove 12, a movable plate 13, a top block 14, a support block 15, a connecting rod 16, a spring 17 and a limiting plate 18, the right end of the anchor sprocket 5 is fixedly connected to the limiting disc 11, and the limiting disc 11 is rotatably connected to the upper end of the right support plate 3. The limiting grooves 12 are equiangularly opened at the edge of the limiting disc 11. The right end of the right support plate 3 is fixedly connected to the support block 15, and a vertical sliding structure is formed between the support block 15 and the movable plate 13. The movable plate 13 drives the top block 14 to engage in the limiting groove 12 at the corresponding position. The lower end of the movable plate 13 is fixedly connected to the connecting rod 16, and a spring 17 is sleeved on the outer surface of the connecting rod 16. A sliding structure is formed between the connecting rod 16 and the limiting plate 18, and the lower end of the limiting plate 18 is inserted into the right end of the right support plate 3. During the rotation of the anchor sprocket 5, the limiting disc 11 is driven to rotate on the upper end of the right support plate 3. During the stationary process, by pulling the limiting plate 18, the limiting plate 18 slides with the connecting rod 16, and the limiting plate 18 squeezes the spring 17, causing the spring 17 to undergo elastic deformation. The limiting plate 18 is separated from the right support plate 3, thereby releasing the limit on the movable plate 13. Then, the movable plate 13 is pulled upward, and the movable plate 13 slides with the support block 15. The movable plate 13 drives the top block 14 to move upward, so that the top block 14 engages in the limiting groove 12 at the corresponding position, thereby facilitating the limitation of the limiting disc 11. Then, the limiting plate 18 is directly released, and the spring 17 resumes elastic deformation, driving the limiting plate 18 to slide with the connecting rod 16. The lower end of the limiting plate 18 is inserted into the corresponding position on the side of the right support plate 3, thereby facilitating the limitation of the movable plate 13. Combining with the movable plate 13 driving the top block 14 to engage in the limiting groove 12 at the corresponding position, it is convenient to limit the limiting disc 11 and realize the locking of the anchor sprocket 5 to prevent the anchor sprocket 5 from rotating.

[0036] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
