Description

Technical Field

[0001] This utility model belongs to the technical field of anchor winch equipment, specifically a safety protection and rapid deployment / retrieval device for anchor winches used for ship berthing. Background Technology

[0002] Anchor winches are machines used on ships to raise and lower anchors and anchor chains. They are powered by human labor, steam engines, electric motors, hydraulic motors, etc., and are typically installed on the forecastle deck. The trend is towards using a single unit to perform anchor raising, mooring, automatic mooring, and mooring operations. Based on the drive method, they can be divided into: manual, electric, and hydraulic. When anchoring, the chosen anchorage must have appropriate water depth. Extremely shallow water can reduce maneuverability and increase resistance. The current direction of the chosen anchorage should be relatively stable, and the current speed should be slow. Furthermore, the anchor's holding power after gripping the bottom is closely related to the bottom material. A muddy, sandy, or clayey bottom with moderate hardness should be selected to enhance the anchor's holding power. Finally, anchor is dropped to secure the ship to the hull. Traditional anchor winches use a motor directly connected to the anchor chain wheel for winding and releasing the anchor chain. Due to the excessive length and weight of the anchor chain, its rapid descent due to inertia can easily damage the motor, preventing the anchor winch from functioning properly. Therefore, a safety protection and rapid winding / rewinding device for ship berthing is needed to address these issues. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a safety protection and rapid deployment / retraction device for anchor winches used for ship berthing. It solves the problem that in traditional anchor winches, where the motor is directly connected to the anchor chain wheel to wind up and release the anchor chain, the excessive length and weight of the anchor chain can easily damage the motor due to the rapid descent caused by inertia, resulting in the anchor winch being unable to operate normally.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a safety protection and rapid deployment / retraction device for ship anchor winches, comprising a base plate, two support plates on the base plate, a rotating shaft rotatably mounted inside the support plates, a fixing plate on the side of the support plates, a worm gear rotatably mounted on the side of the fixing plate, a worm wheel meshing on the side of the worm gear, an anchor chain cylinder rotatably mounted inside the two support plates, the anchor chain cylinder being connected to the rotating shaft, a protective frame on the side of the support plates, a limiting frame on the side of the support plates, a sliding rod slidably connected inside the limiting frame, a brake plate at the top of the sliding rod, buffer pads on both the front and back of the brake plate, and a semi-circular block at the bottom of the sliding rod.

[0005] As a further embodiment of this utility model: a servo motor is provided on the side of the fixing plate, and the output shaft of the servo motor is connected to the worm gear.

[0006] As a further embodiment of this utility model: the worm gear is connected to the rotating shaft, and the rotating shaft is rotatably connected to the fixed plate.

[0007] As a further embodiment of this utility model: two springs are provided inside the protective frame, and a connecting plate is provided at the top of the springs.

[0008] As a further embodiment of this utility model: the connecting plate is connected to the sliding rod, and the sliding rod overlaps with the protective frame.

[0009] As a further embodiment of this utility model: a cylinder is provided on the base plate, and a ramp block is provided at the output end of the cylinder.

[0010] As a further embodiment of this utility model: the ramp block overlaps with the base plate, and the ramp block is located directly below the semicircular block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. The safety protection and rapid deployment / retraction device for the anchor winch used for berthing of this vessel, through the setting of a worm gear, worm, servo motor, ramp block, slide bar, brake plate, and buffer pad, further avoids the situation where the servo motor could be easily damaged by the rapid descent of the anchor chain due to inertia at the moment of lowering. The brake plate and buffer pad physically offset part of the inertial force of the anchor chain at the moment of lowering, thereby reducing the braking burden on the worm gear and worm. This not only allows the worm gear and worm to perform normal and rapid winding and release of the anchor chain, but also improves the overall reliability and safety.

[0013] 2. The safety protection and rapid deployment / retraction device for the ship's anchor winch is equipped with a protective frame, a limiting frame, and a fixing plate. The protective frame protects the internal mechanical structure and prevents accidental damage to the mechanical structure. The limiting frame supports and limits the sliding rod, and its triangular stability prevents the sliding rod from swaying freely within the limiting frame. The fixing plate provides a supporting surface, allowing the worm gear and worm to rotate smoothly. Attached Figure Description

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a safety protection and rapid deployment / retraction device for ship anchor winches, including a base plate 1, two support plates 2 on the base plate 1, a rotating shaft 10 rotatably mounted inside the support plates 2, a fixing plate 13 on the side of the support plates 2, a worm gear 12 rotatably mounted on the side of the fixing plate 13, and a worm wheel 11 meshing with the side of the worm gear 12. By setting the worm wheel 11 and the worm gear 12, a self-locking mechanism is formed through the mutual cooperation of the worm gear 12 and the worm wheel 11, which not only effectively prevents the anchor chain from falling off, but also... Furthermore, the anchor chain can be smoothly extended and retracted. A servo motor 14 is provided on the side of the fixed plate 13. The output shaft of the servo motor 14 is connected to the worm gear 12. The worm wheel 11 is connected to the rotating shaft 10. The rotating shaft 10 is rotatably connected to the fixed plate 13. Anchor chain cylinders 3 are rotatably provided inside the two support plates 2. The anchor chain cylinders 3 are connected to the rotating shaft 10. A protective frame 4 is provided on the side of the support plate 2. By setting the protective frame 4, the internal mechanical structure is protected, further avoiding interference from external debris to the mechanical structure.

[0020] Two springs 18 are installed inside the protective frame 4. A connecting plate 17 is located at the top of each spring 18. By setting the springs 18, their elasticity allows them to return to their original shape, thus enabling the slide rod 6 to drive the brake plate 15 to reset. A limiting frame 5 is located on the side of the support plate 2, and the slide rod 6 is slidably connected within the limiting frame 5. By setting the limiting frame 5 and the slide rod 6, the limiting frame 5 provides support and limits for the slide rod 6, ensuring that the slide rod 6 does not wobble during its up-and-down sliding within the limiting frame 5. A brake plate 15 is located at the top of the slide rod 6, and buffer pads 16 are provided on both the front and back of the brake plate 15. By setting a brake plate 15 and a buffer pad 16, the buffer pad 16 absorbs the inertial force of the anchor chain through its elastic deformation, and works with the brake plate 15 to reduce the impact caused by the sudden stop of the anchor chain cylinder 3 during braking. The bottom end of the slide bar 6 is provided with a semi-circular block 7, the connecting plate 17 is connected to the slide bar 6, the slide bar 6 overlaps with the protective frame 4, the base plate 1 is provided with a cylinder 9, and the output end of the cylinder 9 is provided with a ramp block 8. By setting the semi-circular block 7 and the ramp block 8, under the specific shape of the semi-circular block 7 and the ramp block 8, the mutual compression of the semi-circular block 7 and the ramp block 8 can realize the up and down movement of the slide bar 6. The ramp block 8 overlaps with the base plate 1 and is located directly below the semi-circular block 7.

[0021] The working principle of this utility model is as follows:

[0022] When the anchor chain needs to be lowered, firstly, control cylinder 9 to operate, causing cylinder 9 to push ramp block 8 to move closer to semicircular block 7. Since one side of ramp block 8 is a slope, the slope compresses semicircular block 7 and moves it upward, causing semicircular block 7 to drive slide rod 6 upward. Slide rod 6 drives brake plate 15 and buffer pad 16 to contact and lock with worm gear 11. Due to the large inertial force of the anchor chain falling rapidly under gravity at the moment of lowering, brake plate 15 and buffer pad 16 offset part of the inertial force of the anchor chain, reducing the impact of the sudden braking of anchor chain cylinder 3. Once the anchor chain is taut, control cylinder 9 to drive ramp block 8 to reset, spring 18 returns to its original shape and drives slide rod 6 downward, causing brake plate 15 and buffer pad 16 to separate from worm gear 11. Then, control servo motor 14 to drive worm 12 and worm gear 11 to rotate, thereby realizing the rapid raising and lowering of the anchor chain.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
