Description

Technical Field

[0001] The invention relates to the field of ship mooring piles, in particular to a mooring device for a ship mooring cable. Background Art

[0002] After the ship docks, it needs to use cables to tow the hull and the mooring piles on the shore to prevent the ship from being pushed away from the shore by the waves.

[0003] One end of the cable is fixed on the deck of the ship, and the other end extends to the shore. The staff ties the other end of the cable to a mooring pile. There are usually multiple moors, and the cable can be put on the pile or wrapped between multiple piles to ensure the stability of the ship.

[0004] When the ship needs to sail again, the staff are also required to separate the cable from the mooring pile. If the wind and waves are slightly stronger during the separation process, the hull will pull the cable, making the cable tight. If the staff is dismantling the cable at this time and the cable is suddenly tightened, it is easy to squeeze the staff's fingers on the mooring pile, causing damage to the staff's finger bones. Therefore, there are great safety hazards when removing the cable from the mooring pile. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-Figure 5 The mooring device for a ship mooring cable shown in the figure comprises: a sinking cylinder 1 and an assembly cover 2 rotatably assembled on the top of the sinking cylinder 1, two cable posts 3 equidistantly distributed in a circle are fixedly arranged on the upper end surface of the assembly cover 2, and the two cable posts 3 are used to limit the cable, and the sinking cylinder 1 needs to be buried under the ground, leaving only the assembly cover 2 and the two cable posts 3 on the ground;

[0034] It also includes: a winding unit, used to wind the cable through two cable posts 3, and the winding unit is arranged inside the sinking cylinder 1;

[0035] An anti-falling unit is used to prevent the cables wound on the two cable posts 3 from falling off, and the anti-falling unit is located at the top of the cable posts 3;

[0036] The auxiliary untying unit causes the cable to automatically detach from the two cable posts 3.

[0037] The winding unit includes a partition 4 fixedly mounted inside the sinking cylinder 1, and a reduction motor 5 is fixedly provided on the upper end surface of the partition 4, an inner gear ring 6 is fixedly provided on the lower end surface of the assembly cover body 2, and a first gear 7 movably meshed with the inner gear ring 6 is fixedly provided on the output end of the reduction motor 5. The reduction motor 5 has a large torque and can stably drive the inner gear ring 6 and the assembly cover body 2 to rotate through the first gear 7.

[0038] The anti-falling unit includes an internally threaded cylinder 10 located inside each cable column 3, each internally threaded cylinder 10 is coaxially distributed with the cable column 3, and the bottom of the cable column 3 rotates to penetrate the assembly cover 2, the internal thread of the internally threaded cylinder 10 is equipped with a first threaded rod 11, and the top of the first threaded rod 11 is fixedly provided with a sliding rod 12 that slides through the internally threaded cylinder 10, and the sliding rod 12 also slides axially through the top of the cable column 3, an extension component is provided between the top of the sliding rod 12 and the top of the cable column 3, and a driving component is also provided at the bottom of the internally threaded cylinder 10. Since the sliding rod 12 can only slide axially at the top of the cable column 3, when the internally threaded cylinder 10 rotates, the first threaded rod 11 can be driven to move up and down with the sliding rod 12.

[0039] The extension component includes a plurality of circumferentially equidistant baffles 13 hingedly assembled on the top of the slide bar 12, the baffles 13 are hollow, and a through slot 14 is provided at the bottom of each baffle 13, and a plurality of circumferentially equidistant T-shaped limit frames 15 are fixed to the upper end surface of the cable column 3, the number of the T-shaped limit frames 15 is the same as the number of the baffles 13, and each T-shaped limit frame 15 is slidably engaged with each through slot 14 and the baffle 13. When the slide bar 12 moves downward, the baffle 13 can be expanded outward through the sliding engagement of the T-shaped limit frame 15 with the through slot 14 and the baffle 13.

[0040] The driving component includes a support column 8 fixedly mounted on the top of the partition 4, and the support column 8 is located at the center of the partition 4. A second gear 9 is also fixedly mounted on the top of the support column 8. A third gear 16 is rotatably mounted on the bottom of each internally threaded cylinder 10, and the third gear 16 is meshed with the second gear 9. The inner wall of the third gear 16 is provided with a plurality of first conical grooves 20 equidistantly distributed around the circumference. At least one first slider 17 is radially slidably mounted inside the internally threaded cylinder 10. A first spring 18 is fixedly mounted on one end of the first slider 17 close to the axis of the internally threaded cylinder 10, and a first dome column 19 is fixedly mounted on the other end of the first slider 17. The first dome column 19 slides through the internally threaded cylinder 10, and the end of the first dome column 19 is slidably mounted in the first conical groove 20. When the internally threaded cylinder 10 is restricted and cannot continue to rotate, the continuous rotation of the third gear 16 can push the first dome column 19 out through the first conical groove 20, allowing the third gear 16 to idle on the surface of the internally threaded cylinder 10.

[0041] Working principle: There are generally two types of cable ends, one with a ring and the other without a ring. If it is a cable with a ring, the staff only needs to put the ring on one of the cable posts 3 and then start the reduction motor 5; if it is a cable without a ring, the staff needs to wrap the cable between the two cable posts 3 in an eight-shaped shape and then start the reduction motor 5;

[0042] When the reduction motor 5 is running, the first gear 7 can drive the inner gear ring 6 to rotate, so that the assembly cover 2 can rotate with the two cable posts 3, and the two cable posts 3 can wind up the cable. After the cable is wound up tightly, the ship can be effectively limited.

[0043] When the cover body 2 is assembled and the cable column 3 is wound around the cable, the third gear 16 can be prompted to rotate on the surface of the second gear 9. The third gear 16 can rotate with the internal threaded cylinder 10. Since the slide bar 12 can only slide axially, the first threaded rod 11 can move downward with the slide bar 12, and the baffle 13 is restricted by the T-shaped limit frame 15. When the slide bar 12 moves downward, several baffles 13 can be unfolded to cover the top of the cable column 3, thereby avoiding the risk of the cable moving upward and detaching from the cable column 3.

[0044] When the slide rod 12 moves downward to its maximum value and cannot move further, while the assembly cover body 2 continues to rotate, the larger torsional force generated between the third gear 16 and the internal threaded cylinder 10 can allow the first dome column 19 to retract into the interior of the internal threaded cylinder 10, without affecting the normal rotation of the assembly cover body 2.

[0045] Example 2: Please refer to Figure 6-Figure 10 This embodiment is a further description of the first embodiment. The auxiliary untying unit includes a push plate 31 placed on the upper end of the assembly cover 2, and the push plate 31 is slidably mounted on the outer surfaces of the two cable columns 3. The outer wall of the sinking cylinder 1 is fixed with two symmetrically distributed column cylinders 21. The outer surface of the partition 4 is fixed with a fixing frame 22, and the two ends of the fixing frame 22 extend into the interior of the two column cylinders 21 respectively. The two ends of the column cylinder 21 are rotatably provided with a fourth gear 24, and the internal thread of the fourth gear 24 is equipped with a second threaded rod 23. The top of the second threaded rod 23 slides through the column cylinder 21, and the inner thread of the second threaded rod 23 is An elliptical cylinder 30 is slidably mounted on the inner portion, and the bottom of the elliptical cylinder 30 is fixed to the sub-column tube 21; an outer toothed ring 25 is rotatably sleeved on the outer surface of the inner toothed ring 6, and the outer toothed ring 25 is movably engaged with the fourth gear 24; a docking component is arranged between the top of each second threaded rod 23 and the push plate 31, and a clamping component is arranged between the inner toothed ring 6 and the outer toothed ring 25; when the assembled cover body 2 is reset and reversed with the cable column 3, the fourth gear 24 can be driven by the outer toothed ring 25 during the process of loosening the cable, and the second threaded rod 23 can be moved upward under the axial restriction of the elliptical cylinder 30, and the maximum height of the movement does not exceed the height of the cable column 3.

[0046] The docking component includes a supporting rod 33 fixedly arranged on the top of each second threaded rod 23, and the supporting rod 33 and the second threaded rod 23 are vertically distributed, and the end of the supporting rod 33 away from the second threaded rod 23 faces the push plate 31, and the outer surface of the push plate 31 is provided with an annular groove 32, and the supporting rod 33 is slidably assembled with the annular groove 32. When the second threaded rod 23 moves upward, the push plate 31 can be lifted upward by the engagement of the supporting rod 33 and the annular groove 32.

[0047] The engaging component includes a plurality of second conical grooves 29 equidistantly distributed circumferentially on the outer surface of the inner gear ring 6, at least one second slider 26 is slidably mounted inside the outer gear ring 25, and the second slider 26 is radially distributed circumferentially on the periphery of the inner gear ring 6, a second dome column 28 is fixedly arranged at one end of the second slider 26 close to the inner gear ring 6, and a second spring 27 is arranged at the other end of the second slider 26, the second dome column 28 slides through the outer gear ring 25, and the exposed end of the second dome column 28 is slidably mounted in the second conical groove 29, when the second threaded rod 23 is restricted and cannot move upward or downward, the continuous rotation of the inner gear ring 6 can also allow the second conical groove 29 to push the second dome column 28 out, allowing the inner gear ring 6 to idle inside the outer gear ring 25.

[0048] The push plate 31 is in the shape of a disk, and the disk-shaped push plate 31 can ensure that the supporting rod 33 is always installed in the inner part of the annular groove 32.

[0049] The upper end surface of the push plate 31 is a convex circular surface, and the convex circular surface can better push out the cable wound on the cable column 3.

[0050] In this embodiment: when it is necessary to release the cable, the assembly cover 2 can be driven to reverse by the reduction motor 5. During the reversal process, the cable wound on the surface of the cable column 3 will be slowly relaxed, and the unfolded baffle 13 will be reset and retracted again. Moreover, when the inner gear ring 6 and the outer gear ring 25 are reversed, the fourth gear 24 can be driven to rotate inside the fixing frame 22. Since the second threaded rod 23 is restricted by the elliptical cylinder 30, the rotation of the fourth gear 24 can make the second threaded rod 23 move upward. Through the sliding engagement of the supporting rod 33 and the annular groove 32, when the two second threaded rods 23 move upward, the push plate 31 can be raised on the surface of the two cable columns 3. The cables wound on the surface of the two cable columns 3 are pushed upward by the push plate 31, so that the cables can be detached from the surface of the cable column 3.

[0051] Through the above method, the cable wrapped around the surface of the cable post 3 can be removed instead of the staff. Since the direct contact between the staff and the cable is avoided, in windy and choppy weather, even if the ship pulls the cable and makes the cable tightly connected to the cable post 3, the cable can be quickly detached from the surface of the cable post 3 by moving the push plate 31, thereby ensuring the safety of cable loading and unloading.
