Description

Technical Field

[0001] This utility model relates to the field of fishing boat component technology, specifically to a lifting mooring bollard for fishing boats. Background Technology

[0002] Fishing boats are vessels used for catching and harvesting aquatic plants and animals. They also include auxiliary vessels in modern fishing production, such as those used for seafood processing, transportation, aquaculture, resource surveys, fisheries guidance and training, and fisheries administration. Mooring bollards are posts used to secure mooring lines.

[0003] Existing marine mooring bollards are usually fixedly installed on the deck, bow, or stern of a ship. Fixed installation of mooring bollards is neither aesthetically pleasing nor safe, and they cannot be hidden inside the hull structure, making them inconvenient to use. Summary of the Invention

[0004] This utility model proposes a liftable mooring bollard for fishing boats, which solves the problem that existing mooring bollards are inconvenient to lift and hide, thus posing certain safety hazards.

[0005] The technical solution of this utility model is as follows: A lifting mooring bollard for fishing vessels includes a hull structure. Mounting slots are respectively provided on the two side decks at the bow of the hull structure. A cover plate is installed on the top of each mounting slot. A support sleeve is embedded within the hull structure below the mounting slot. A lifting rod is slidably connected inside the support sleeve. The top of the lifting rod extends out of the cover plate and its end is connected to a limit block. A support frame is fixedly installed within the hull structure below the support sleeve. A guide frame is fixedly installed on the top of the support frame. A fixing sleeve is fixedly connected to the middle of the guide frame. The bottom of the support sleeve is fixedly connected to the top of the fixing sleeve. Connecting rods are fixedly connected to both sides of the bottom of the lifting rod, and connecting seats are fixedly connected to one side of each connecting rod. A support rod is rotatably connected inside the connecting seat, and a support seat is rotatably connected to the bottom end of each support rod.

[0006] Preferably, the guide frame is internally rotatably connected to a bidirectional screw, and both sides of the bidirectional screw are threadedly connected to threaded sleeves. The top of the guide frame is provided with sliding holes on both sides, and the bottom end of the support base passes through the sliding holes and is fixedly connected to the top of the threaded sleeves.

[0007] Preferably, a threaded groove is provided in the middle of the top end of the lifting rod, and a lead screw is fixedly connected to the middle of the bottom end of the limiting block, with the lead screw threaded inside the threaded groove.

[0008] Preferably, guide holes are provided on both sides of the support sleeve, and one end of the connecting rod is slidably connected inside the guide holes.

[0009] Preferably, a drive motor is fixedly connected to one side of the guide frame, and one end of the output shaft of the drive motor passes through the guide frame and is fixedly connected to one end of the bidirectional screw.

[0010] Preferably, the cross-section of the limiting block is an outwardly convex arc shape.

[0011] The beneficial effects of this utility model are as follows: In this invention, a lifting rod is used to attach a cable, and a limiting block prevents the cable from slipping off the top of the lifting rod. A control motor drives a bidirectional screw to rotate, causing the threaded sleeve to move in opposite directions. This, in turn, causes the support base to slide on the guide frame. The support rod can pull the connecting seat up and down, facilitating the sliding of the connecting rod within the guide hole. This allows the connecting rod to drive the lifting rod to slide up and down within the support sleeve, enabling height adjustment of the lifting rod to a suitable height for raising and lowering the mooring bollard. Furthermore, the lifting rod can be controlled to move downwards to its lowest position, allowing for easy concealment of the mooring bollard and preventing obstruction for users loading and unloading goods, thus mitigating certain safety hazards.

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the embodiments of this utility model.

[0015] Please see Figure 1-5A type of lifting mooring bollard for fishing vessels includes a hull structure 1. Circular mounting slots 19 are respectively opened on the two side decks at the bow of the hull structure 1. A cover plate 20 is installed on the top of the mounting slots 19. A support sleeve 2 is embedded in the hull structure 1 below the mounting slots 19. A lifting rod 3 is slidably connected inside the support sleeve 2. The support sleeve 2 provides stable support for the lifting rod 3, preventing it from shifting position during vertical movement. The top of the lifting rod 3 extends out of the cover plate 20 and is connected to a limiting block 4. The lifting rod 3 is the mooring bollard. The limiting block 4 limits the mooring rope, preventing it from slipping off the outside of the lifting rod 3. After the mooring rope is attached, the limiting block 4 moves downward to press the rope firmly against the cover plate 20, maintaining stability and preventing slippage.

[0016] Preferably, the upper side of the cover plate 20 is in a horizontal state, so that the limiting block 4 can be smoothly lowered to fit the upper side of the cover plate 20, and the lower side of the cover plate 20 fits the side deck of the hull structure 1.

[0017] A support frame 18 is fixedly installed inside the hull structure 1 located below the support sleeve 2. A guide frame 7 is fixedly installed on the top of the support frame 18. A fixing sleeve 5 is fixedly connected to the middle of the guide frame 7. The bottom of the support sleeve 2 is fixedly connected to the top of the fixing sleeve 5. Fixing plates 16 are fixedly connected to both sides of the bottom end of the guide frame 7. Fixing holes 17 are opened at the four corners of the fixing plates 16. By inserting bolts through the fixing holes 17, the fixing plates 16 can be stably installed inside the hull structure 1, so that the guide frame 7 and the hull structure 1 remain stable.

[0018] Preferably, the thickness of the limiting block 4 gradually decreases from the middle to both ends, and the upper surface is in the shape of an outwardly convex arc, which reduces the protrusion height of the limiting block 4 so that it can be better integrated into the hull structure 1.

[0019] Both sides of the bottom of the lifting rod 3 are fixedly connected to connecting rods 13. Both sides of the support sleeve 2 are provided with guide holes 6. One end of the connecting rod 13 is slidably connected to the inside of the guide hole 6. The guide hole 6 can limit the position of the connecting rod 13 and prevent the connecting rod 13 from deflecting during the up and down movement. One side of the connecting rod 13 is fixedly connected to a connecting seat 14. The inside of the connecting seat 14 is rotatably connected to a support rod 12. The bottom end of the support rod 12 is rotatably connected to a support seat 11. The two ends of the support rod 12 are rotatably connected to the inside of the support seat 11 and the connecting seat 14. As the support seat 11 moves, the support rod 12 can drive the connecting seat 14 to move up and down, thereby facilitating the control of the height of the lifting rod 3 and making it easy to fix the cable.

[0020] Please see Figure 4The guide frame 7 is internally connected to a bidirectional screw 8, and threaded sleeves 9 are threadedly connected to both sides of the bidirectional screw 8. Sliding holes 10 are opened on both sides of the top of the guide frame 7. The bottom ends of the support seats 11 pass through the sliding holes 10 and are fixedly connected to the top of the threaded sleeves 9. A drive motor 15 is fixedly connected to one side of the guide frame 7. One end of the output shaft of the drive motor 15 passes through the guide frame 7 and is fixedly connected to one end of the bidirectional screw 8. The drive motor 15 drives the bidirectional screw 8 to rotate, so that the bidirectional screw 8 can perform threaded transmission with the threaded sleeves 9 at both ends, which can drive the two support seats 11 to move in opposite directions. By controlling the rotation direction and the number of rotations of the drive motor 15, the position of the support seats 11 can be easily controlled, thereby facilitating the control of the height of the lifting rod 3 and the installation and fixing of the cable.

[0021] Please see Figure 5 A threaded groove 21 is provided in the middle of the top of the lifting rod 3. A lead screw 22 is fixedly connected to the middle of the bottom of the limiting block 4. The lead screw 22 is threaded into the inside of the threaded groove 21. By threading the lead screw 22 into the inside of the threaded groove 21, the limiting block 4 can be stably installed on the top of the lifting rod 3. By rotating the limiting block 4 in the opposite direction, the lead screw 22 can be moved out of the inside of the threaded groove 21, which can be easily replaced according to different installation methods of the cable. By installing the lead screw 22 into the inside of the threaded groove 21, the limiting block 4 is firmly installed on the top of the lifting rod 3. As the lifting rod 3 is controlled to descend, the limiting block 4 can firmly press the cable onto the top of the hull structure 1, which can prevent the cable from falling off during use and keep the cable stable.

[0022] The working principle and usage process of this utility model are as follows: When it is necessary to raise the mooring bollard, the drive motor 15 is controlled to rotate forward, driving the bidirectional screw 8 to rotate, so that the bidirectional screw 8 respectively engages with the threaded sleeve 9, causing the two threaded sleeves 9 to move towards the center, driving the two support seats 11 to move closer to each other, thereby causing the tops of the two support rods 12 to rotate inside the connecting seat 14, which can drive the connecting rod 13 to slide upward inside the guide hole 6, and drive the lifting rod 3 to slide upward inside the support sleeve 2, which can lift the mooring bollard upward, making it convenient to tie the cable to it. After the cable is fixed, the drive motor 15 is controlled to rotate in reverse, which can drive the two support seats 11 to move in the opposite direction, thereby causing the support rod 12 to pull the connecting rod 13 downward, causing the lifting rod 3 to move downward, driving the limiting block 4 to press the cable tightly against the bow of the hull structure 1, which can fix the cable and prevent the cable from falling off.

[0023] In addition, when the limit block 4 needs to be replaced, the limit block 4 is rotated in the opposite direction to drive the lead screw 22 to rotate inside the threaded groove 21, the lead screw 22 is removed from the threaded groove 21, the limit block 4 is replaced, and then the limit block 4 is stably installed on the top of the lifting rod 3 by installing the lead screw 22 inside the threaded groove 21.

[0024] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
