Description

Technical Field

[0001] This invention belongs to the field of ship mooring technology, specifically relating to a ship mooring buoy cable guide device. Background Technology

[0002] Small vessels can be moored by anchor or by buoys when going to sea. The process of anchoring is relatively slow, while the process of mooring buoys is relatively simple. To moor a buoy, simply pass the cable through the eyelet of the buoy, pull back the end of the cable, and tie it to the bollard.

[0003] The existing method of mooring buoys requires two struts. First, a guide rope is tied to the end of the guide strut, with a loop left at the end of the guide rope. The guide strut is used to pass the loop of the guide rope through the buoy eyelet. The other strut, with a hook at the end, hooks the loop of the cable and pulls it back. In the existing technology, the cable eyelet is prone to coming off during the mooring process. When the bow is high above the sea surface, due to the ship's rolling and the strut's shaking, it is difficult for the guide strut to pass the cable through the buoy eyelet in one go. The mooring process is relatively slow and requires the bridge crew to move the ship multiple times to change the ship's attitude, resulting in low efficiency.

[0004] To address the shortcomings of existing mooring pontoons, it is necessary to design a mooring pontoon cable guide device to facilitate the rapid passage of the cable through the pontoon eye ring, thereby improving the efficiency and reliability of mooring pontoons. Summary of the Invention

[0005] Based on the above description, the present invention provides a solution to the technical problems in the prior art.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A marine mooring buoy cable guide device, comprising: The outer shell assembly includes a shell with an internal receiving space, the upper end of the shell having a through hole communicating with the outside, and the lower end of the shell having a recessed notch for engaging with the eye ring sidewall of the float, with a first opening and a second opening formed on both sides of the notch, respectively. A motion guide assembly includes an arc-shaped toothed ring, a connector, and a traction mechanism. The toothed ring is rotatably disposed on the housing. The toothed ring has a traction end extending from the first opening. The traction end can reciprocate between the first opening and the second opening with the toothed ring, so that the toothed ring and the notch form a closed loop or an open loop. The connector is connected to the traction end. The traction mechanism is detachably connected to the connector. A guide rope is connected to the traction mechanism. The drive assembly includes a push rod, a gear mechanism connected to the push rod, and a gear transmission structure installed inside the housing. The push rod extends into the housing through the through hole, and the gear mechanism drives the gear ring to rotate through the gear transmission structure. The housing is provided with a locking mechanism for locking the traction mechanism and an unlocking mechanism for separating the connector from the traction mechanism, corresponding to the second opening.

[0007] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: The marine buoy mooring cable guide device provided in this application uses a push rod to drive a gear mechanism. The gear mechanism and gear transmission structure drive the gear ring to rotate, thereby driving the traction mechanism connected to the guide rope to pass through the eye ring of the buoy, realizing the guide rope passing through the eye ring hole. It is simple to use, adopts a pure mechanical structure, has high operational reliability, can effectively shorten the time for mooring and unmooring the buoy, and improve the single success rate of mooring and unmooring the buoy. It can be widely used in the operation of mooring buoys on existing ships.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the gear condition includes a U-shaped portion and a drive rack and a return rack spaced apart at both ends of the U-shaped portion. The drive rack and the return rack are parallel to each other and staggered along the length direction. The drive rack is positioned away from the U-shaped portion relative to the return rack. The drive rack and the return rack respectively drive the gear transmission structure to output opposite rotational driving forces, so that the gear ring rotates in opposite directions.

[0010] Furthermore, the gear transmission structure includes a driving gear set and a driven gear set. The driving gear set includes a driving driving gear, a reset driving gear, and an output driving gear arranged coaxially.

The output driving gear is used to transmit the input driving force to the driven gear set.

[0011] Furthermore, the gear transmission structure also includes a first internal meshing ratchet and a second internal meshing ratchet. A first internal ratchet gear ring is formed on the inner side of the output drive gear. The first internal meshing ratchet is fitted inside the first internal ratchet gear ring and is coaxially fixed with the drive drive gear. When the drive rack is reset upwards and drives the drive drive gear to rotate, the output drive gear is fixed. A second internal ratchet gear ring is formed on the inner side of the reset drive gear. The second internal meshing ratchet is fitted inside the second internal ratchet gear ring and is coaxially fixed with the drive drive gear. When the reset rack is reset upwards and drives the reset drive gear to rotate, the output drive gear is fixed.

[0012] Furthermore, the connector includes a shaft portion fixed to the traction end and an outward protrusion connected to one end of the shaft portion; The traction mechanism includes a housing and a movable gripper.

[0014] Furthermore, the movable gripper includes a fixed disk, a claw, an elastic element, and an end cap. The housing is hollow and through. The fixed disk is slidably disposed inside the housing. The claw is hinged to one end of the fixed disk. The end cap is connected to the other end of the fixed disk. The movable gripper is configured such that when the fixed disk moves toward the end cap, the claw retracts and clamps under the limitation of the side wall of the housing. The elastic element is used to force the fixed disk to move toward the end cap. The housing can enter the interior of the housing through the second opening. The unlocking mechanism includes a cam that can press against the end cap to move the fixed plate away from the end cap.

[0015] Furthermore, the unlocking mechanism also includes a movable rod, a reset component, and a fixing component. The movable rod is rotatably mounted on the housing.

It should also be understood that the terms “comprising,” “including,” or “having,” etc., specify the presence of the stated feature, whole, step, operation, component, part, or combination thereof, but do not preclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts, or combinations thereof.

[0024] like Figure 1 As shown in the figure, this application provides a marine mooring buoy cable guide device, which includes a housing assembly 10, a guiding motion assembly 20, and a drive assembly 30.

[0025] Among them, such as Figure 2 As shown, the outer shell assembly 10 includes a shell 11 with an internal accommodating space. The upper end of the shell 11 has a through hole communicating with the outside. The lower end of the shell 11 has a recessed notch 11a for engaging with the side wall of the eye ring (not shown) of the float. A first opening 11b and a second opening 11c are formed on both sides of the notch 11a, respectively.

[0026] In a preferred embodiment of this application, the notch 11a is a semi-circular concave shape with a radius matching the radial cross-section of the eye ring, which facilitates contact with the sidewall of the eye ring.

[0027] The guiding motion assembly includes an arc-shaped toothed ring 21, a connector 22, and a traction mechanism 23. The toothed ring 21 is rotatably mounted on the housing 11. In this application, a semi-circular track 111 is formed inside the housing 11 along the inner side of the notch 11a. The toothed ring 21 is movably mounted on the track 111. The toothed ring 21 is approximately semi-circular with serrations on its outer side. The toothed ring 21 has a traction end 211 extending from the first opening 11b. The traction end 211 can reciprocate between the first opening 11b and the second opening 11c with the toothed ring 21, so that the toothed ring 21 and the notch 11a form a closed loop or an open loop. According to the above, a closed loop is a circular ring structure, and an open loop is any non-closed annular structure from the semi-circular notch to the circular ring. The connector 22 is connected to the traction end 211. The traction mechanism 23 is detachably connected to the connector 22. A guide rope 40 is connected to the traction mechanism 23. The guide rope 40 is connected to the traction mechanism 23 by tying or snapping.

[0028] When the notch 11a abuts against the side wall of the eye ring, during the process of the traction end 211 moving from the open ring to the closed ring, the traction mechanism 23 passes through the eye ring hole, like threading a wire, so that the guide rope 40 passes through the eye ring hole.

[0029] The drive assembly 30 includes a push rod 31, a gear condition 32 connected to the push rod 31, and a gear transmission structure 33 installed inside the housing 11. The push rod 31 extends into the housing 11 through the through hole, and the gear condition 32 drives the gear ring 21 to rotate through the gear transmission structure 33.

[0030] In a preferred embodiment of this application, combined with Figure 3 As shown, the gear condition 32 includes a U-shaped portion 321 and a drive rack 322 and a return rack 323 spaced apart at both ends of the U-shaped portion 321. The drive rack 322 and the return rack 323 are parallel to each other and staggered along the length direction. The drive rack 322 is positioned away from the U-shaped portion 321 relative to the return rack 323 to ensure that the drive rack 322 and the return rack 323 do not simultaneously contact the gear transmission structure 33 for transmission. Specifically, the drive rack 322 and the return rack 323 drive the gear transmission structure 33 to output opposite rotational driving forces so that the gear ring 21 rotates in opposite directions.

[0031] Understandably, the drive rack 322 is used to rotate the gear ring 21 from the open ring to the closed ring, which is called forward motion, and the reset rack 323 is used to rotate the gear ring 21 from the closed ring to the open ring, which is called reverse motion. Through the setting of forward and reverse motion, the push rod 31 realizes the threading and retraction of the gear ring 21 during the unidirectional pushing process, realizing the entire threading action. The structure is simple and the operation is convenient.

[0032] Combination Figure 2 As shown, the housing 10 is provided with a locking mechanism 50 for locking the traction mechanism 23 and an unlocking mechanism 60 for separating the connector 22 and the traction mechanism 23, corresponding to the second opening 11c.

[0033] The locking mechanism 50 ensures that when the traction mechanism 23 drives the guide rope 40 to move through the eyelet and remain on the other side of the eyelet, the unlocking mechanism 60 separates the connector 22 and the traction mechanism 23, ensuring that the toothed ring 21 will not drive the traction mechanism 23 when it retracts, thus ensuring the positional stability of the guide rope 40 and the smooth retraction of the toothed ring 21.

[0034] Among them, the gear transmission structure 33, which is equipped with gear transmission characteristics, can be divided into a driving gear set 331 and a driven gear set 332, combined with Figure 4As shown, the drive gear set 331 includes a drive drive gear 3311, a reset drive gear 3312, and an output drive gear 3313, which are coaxially arranged. Due to the axial positional relationship between the drive drive gear 3311 and the reset drive gear 3312, the drive rack 322 and the reset rack 323 are staggered in the axial direction of the drive gear set 331. Specifically, the drive rack 322 cooperates with the drive drive gear 3311, and the reset rack 323 cooperates with the reset drive gear 3312. The output drive gear 3313 is used to transmit the input driving force to the driven gear set 332.

[0035] It is understood that the driven gear set 332 is composed of at least one level of gear meshing. It is only necessary to ensure that the last level of gear meshes with the outer side of the gear ring. For example, in this application, the driven gear set 332 is composed of two levels of gear meshing with transmission amplification characteristics, thereby ensuring that a large rotation distance of the gear ring is achieved with a small driving distance. In other embodiments, those skilled in the art can design gear transmission chains with more or fewer levels according to actual needs, which is not limited here.

[0036] In a more preferred embodiment of this application, in order to ensure that the toothed ring 21 remains stationary during the pull-back process of the push rod 31, combined with Figure 5 and Figure 6 As shown, the gear transmission structure 33 also includes a first internal meshing ratchet 334 and a second internal meshing ratchet 335. A first internal ratchet gear ring is formed on the inner side of the output drive gear 3313. The first internal meshing ratchet 334 is fitted inside the first internal ratchet gear ring and is coaxially fixed with the drive drive gear 3311. When the drive rack 322 is reset upwards and drives the drive drive gear 3311 to rotate, the output drive gear 3313 is fixed. A second internal ratchet gear ring is formed on the inner side of the reset drive gear 3312. The second internal meshing ratchet 335 is fitted inside the second internal ratchet gear ring and is coaxially fixed with the drive drive gear 3311. When the reset rack 323 is reset upwards and drives the reset drive gear 3312 to rotate, the output drive gear 3313 is fixed.

[0037] It is understandable that the intermittent engagement between the internal ratchet and the internal ratchet gear ring, which enables unidirectional motion control of the external internal ratchet gear ring, is a common steering control method in mechanical structures, and will not be elaborated on here.

[0038] In the embodiments of this application, the connector 22 includes a shaft portion 221 fixed to the traction end 211 and an outward protrusion 222 connected to one end of the shaft portion 221. It can be understood that, in order to facilitate the fixing of the shaft portion 22, the traction end 211 can be configured as a connecting plate or a connecting block. In this embodiment, the traction end 211 is configured as a connecting plate with a threaded hole, and the shaft portion 22 is fixed to the connecting plate of the traction end 211 by a threaded engagement.

[0039] The traction mechanism 23 includes a housing 231 and a movable gripper 232, which are combined with Figure 7 and Figure 8 As shown, the outer side of the casing 231 has a connecting ring 233 for connecting with the guide rope 40. The guide rope 40 can be connected to the connecting ring 233 by tying or snapping, so as to ensure that the guide rope 40 can move with the casing 231 and will not fall off.

[0040] The movable gripper 232 can be used to grip the protruding part 222, and the unlocking mechanism 60 is used to release the movable gripper 232 from gripping the protruding part 222.

[0041] As shown in the above structure, the locking mechanism 50 locks the traction mechanism 23, which is equivalent to locking the housing 231. In optional embodiments, it can be achieved by means of spring pin, rotatable elastic card, magnetic connection, etc. In this embodiment, the locking structure 50 includes elastic cards 51 provided on both sides corresponding to the second opening 11c. The elastic cards 51 are rotatably connected to the housing 11 by torsion spring. The outer side of the housing 231 has a slot for engaging with the elastic cards 51. In order to ensure connection stability and smoothness before engagement, the slot is designed as a wedge structure and a step is formed at the engagement point.

[0042] Among them, combined Figure 9 and Figure 10 As shown, the movable gripper 232 includes a fixed disk 2321, a claw 2322, an elastic element 2323, and an end cap 2324. Specifically, the housing 231 is hollow and through-hole. The fixed disk 2321 is slidably disposed inside the housing 231. The claw 2322 is hinged to one end of the fixed disk 2321, and the end cap 2324 is connected to the other end of the fixed disk 2321. The movable gripper 232 is configured such that when the fixed disk 2321 moves toward the end cap 2324, the claw 2322 retracts and clamps under the limitation of the side wall of the housing 231. The elastic element 2323 is used to force the fixed disk 2321 to move toward the end cap 2324. The housing 231 can enter the interior of the housing 11 through the second opening 11c.

[0043] In this embodiment, the elastic element 2323 includes a spring installed inside the housing 231 and connected to the fixed disk 2321, which maintains an elastic driving force that moves the fixed disk 2321 toward the end cover 2324.

[0044] The unlocking mechanism 60 includes a cam 61 that can move the fixed plate 2321 away from the end cover 2324 by pressing against the end cover 2324.

[0045] The rotation of cam 61 causes the protruding part of cam 61 to press against end cover 2324, thereby causing fixed plate 2321 to move. Claw 2322 disengages from housing 231. After the limiting effect of the side wall of housing 231 is removed, claw 2322 releases the clamping of the protrusion 222, thus realizing the separation and unlocking of connector 22 and traction mechanism 23.

[0046] Preferably, the unlocking mechanism 60 further includes a movable rod 62, a reset member 63, and a fixing member 64. The movable rod 62 is rotatably mounted on the housing 11. The fixing member 62 is fixedly connected to the housing 11 and disposed on one side of the movable rod 62. The cam 61 is coaxially fixedly connected to the movable rod 62. The reset member 63 is connected to the movable rod 62 to drive the cam 61 to rotate to the side away from the second opening 11c. Here, the reset member 63 is preferably a torsion spring, and the rotation of the cam 61 can be achieved by moving the movable rod 62.

[0047] To facilitate the easy movement of the movable lever 62, the drive assembly 30 also includes an unlocking lever 34. The unlocking lever 34 and the tooth condition 32 are connected to the end of the push rod 31 via a connecting plate 35. The unlocking lever 34 is used to push the movable lever 62 to rotate the cam 61 toward the second opening 11c. When the sleeve 231 enters the housing 11 from the second opening 11c, the end cover 2324 is correspondingly set with the cam 61. By using the unlocking lever 34 to move the movable lever 62, the cam 61 is driven to rotate. The protruding part of the cam 61 presses against the end cover 2324 to unlock.

[0048] To ensure the separation and unlocking of the connector 22 and the traction mechanism 23 is located between the extension and retraction of the gear ring and to ensure the overall continuity of the movement, the drive rack 322 and the reset rack 323 are spaced apart along the length direction with a blank stroke. The unlocking lever 34 is configured to contact and push the movable rod 62 when the blank stroke corresponds to the drive gear set 331. That is, during the continuous pushing process of the push rod 31, the drive rack 322 first contacts and drives the drive gear set 331, the gear ring 21 extends until it closes, and then enters the blank stroke process. During this process, the unlocking lever 34 moves the movable rod 62 to unlock the connector 22 and the traction mechanism 23. Then the reset rack 323 contacts the drive gear set 331, and the gear ring 21 retracts until it becomes a semi-circular open loop.

[0049] In the embodiments of this application, in order to facilitate the pushing and guiding of the push rod 31, the housing assembly 10 further includes a guide sleeve 12. The guide sleeve 12 is provided with a corresponding through hole for guiding the movement of the push rod 31. A reset elastic element (not shown in the figure) is provided inside the guide sleeve 12 for the return reset after the push rod 31 is pushed. The reset elastic element is preferably a compression spring fitted on the push rod 31.

[0050] To better understand the technical solution of this application, the usage process of this application is described below: In the specific implementation of this scheme, the active mechanism is push rod 31. The operator aligns the notch 11a at the lower end of the shell 11 with the side wall of the float eye ring and presses down forcefully, so that the guide rope 40 can pass through the eye ring. The implementation process is divided into four steps: 1. Guide rope with 40mm perforation: The rotation of the gear ring 21 around the rotation center is achieved by the gear transmission structure 33 meshing with it. The gear transmission structure 33 controls the direction and rotation angle through the tooth condition 32 connected to the end of the push rod 31.

[0051] First, press the end cap 2324 in advance, and hold the outer protrusion 222 of the connector 22 on the movable gripper 232. Connect the guide rope 40 to the connecting ring 233. Then, align the notch 11a at the lower end of the housing 11 with the side wall of the float eye ring. When the push rod 31 is pressed down, the gear condition 32 moves downward under the action of the push rod 31, driving the rack 322 to drive the drive gear 3311 of the drive gear set 331 to rotate. The drive gear 3311 drives the gear ring 21 to rotate through the driven gear set 332, thereby realizing the forward movement of the gear ring. This drives the traction mechanism 23 to move from the first side opening 11b through the center hole of the float eye ring to the second side opening 11c. Since the guide rope 40 is connected to the connecting ring 233, the guide rope 40 passes through the hole.

[0052] 2. Locking of traction mechanism 23 As the housing 231 rotates with the gear ring 21, it enters the housing 11 through the second opening 11c. The housing 231 abuts against the elastic card 51, causing it to rotate until the end of the elastic card 51 engages with the slot on the side wall of the housing 231. The housing 231 is then locked inside the housing. At this time, the guide rope 40 is also fixed to the other side of the float eye ring.

[0053] 3. Unlocking connector 22 Continue pushing the push rod 31, and the gear condition 32 enters the blank stroke process. The unlocking lever 34, driven by the push rod 31, contacts the movable rod 62, pushing the movable rod 62 to drive the cam 61 to rotate. The protruding part of the cam 61 presses against the end cover 2324, causing the fixed plate 2321 to move. The pawl 2322 disengages from the housing 231. After the limitation of the side wall of the housing 231 is removed, the pawl 2322 releases the clamping of the external protrusion 222, realizing the separation and unlocking of the connecting piece 22 and the traction mechanism 23.

[0054] 4. Retraction of gear ring 21 Continue pushing the push rod 31. The reset rack 323 of the gear condition 32 contacts and drives the reset drive gear 3313 of the drive gear set 331. The reset drive gear 3313 drives the gear ring 21 to rotate in the opposite direction through the driven gear set 332, realizing the reverse movement of the gear ring until it is completely retracted to the traction end 211 and reaches the first side opening 11b. Then the pushing force on the push rod 31 is released, and the push rod 31 resets upward under the action of the compression spring. Due to the presence of the two internal meshing ratchets, the drive drive gear 3311 is fixed, and the position of the gear ring 21 is also fixed. At this time, the operator can retract the cable guide device.

[0055] In summary, the cable guide device provided in this application drives the toothed condition 32 through the push rod 31. The toothed condition 32 and the gear transmission structure 33 drive the gear ring 21 to rotate, thereby driving the traction mechanism 23 connected to the guide rope 40 to pass through the eye ring of the float, realizing the insertion of the guide rope 40 through the eye ring hole. It is simple to use, requiring only the push rod 31 to be pushed throughout the process. The pure mechanical structure has high reliability and can effectively shorten the time for mooring and unmooring the float, improve the success rate of mooring and unmooring the float, and can be widely used in the operation of mooring floats on existing ships.

[0056] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
