Description

Technical Field

[0001] This invention belongs to the field of anchorage fixing technology, specifically an anchorage fixing device for ships. Background Technology

[0002] Mooring anchorage refers to a method of anchoring a vessel to a berth by connecting the hull to fixed shore facilities (mooring bollards, buoys, etc.) using multiple mooring lines (such as headlines, sternlines, and crosslines) when berthing at a dock, quay, or buoy, thus achieving stable anchoring. Its core function is to replace traditional anchoring and it is suitable for restricted waterways such as ports and inland waterways.

[0003] Currently, ships need to be secured with mooring lines when berthing at docks. The traditional manual mooring method uses the figure-eight method: the operator first wraps the end of the mooring line clockwise around the bollard once, crosses it, and then wraps it in the opposite direction a second time to form a figure-eight structure. Finally, the end is secured with a stop knot. Although this method can provide reliable mooring force, when untying the mooring line upon departure, the operator must manually untangle the figure-eight wrap layer by layer and loosen the stop knot. Especially in bad weather or when the tide changes drastically, the operator must work close to the stressed mooring line, which poses risks such as the mooring line breaking and rebounding, personnel falling into the water, or limb entanglement. Moreover, the efficiency of the operation is limited by the experience and reaction speed of the personnel. Therefore, a ship anchoring device is proposed. Summary of the Invention

The second docking component has a slot for attaching ship cables; The support frame has a first through hole on its side, and the traction rope passes through the first through hole; The traction rope is initially wrapped around the outside of the winding assembly; The ship's cable is attached to the slot on the second docking component. The traction rope is wound up by a winch, and the ship's cable is wrapped around the outside of the winding assembly under the action of the traction rope.

[0006] Preferably, the first docking member is provided with a first elastic member that supports the frustum transmission member, and the first docking member is provided with a protruding stop member; The frustum transmission component is externally fixed with a magnet.

[0007] Preferably, the outer diameter of the first mating member is smaller than the inner diameter of the first through hole; Initially, under the action of the first elastic member, the second docking member causes the slot to be located inside the first docking member. The outer side of the frustum transmission member abuts against the inner wall of the protrusion member, causing the outer end of the protrusion member to protrude out of the first docking member. Under the action of the protrusion member, the first docking member cannot pass through the first through hole. The second docking member is pulled out, the ship's cable is hooked onto the slot, and the protruding part retracts into the first docking member under the action of the magnet.

[0008] Preferably, the winding assembly includes two winding rollers, and vertical grooves are symmetrically provided on both sides of the support frame, and the two winding rollers slide in the vertical grooves by means of a slider; Pressure blocks are staggered on the opposite surfaces of the two winding rollers, and support members are staggered on the outside of the two winding rollers.

[0009] Preferably, the support frame is provided with a guide wheel for limiting the movement of the traction rope; The traction rope is guided by a guide wheel through the support of the upper winding roller, then around the support of the lower winding roller, and passes between the two winding rollers.

[0010] Preferably, the winding assembly further includes a first sleeve fixed to both sides of the support frame, with pistons fitted at both ends of the first sleeve, and the slider is fixedly connected to the pistons through a connecting frame.

[0011] Preferably, the sealing assembly includes transverse sliding grooves on both sides of the support frame, a transmission frame is slidably disposed inside the transverse sliding grooves, and a second through hole is provided in the middle of the transmission frame, through which the traction rope passes; The inner diameter of the second through hole is larger than the outer diameter of the first mating part.

[0012] Preferably, a second sleeve is fixedly installed in the middle of the first sleeve, a fixing member is fixedly installed inside the second sleeve, a guide rod is sleeved inside the second sleeve, the guide rod is fixedly connected to the transmission frame, and a valve block adapted to the fixing member is fixedly installed at the end of the guide rod. A valve ring is movably fitted in the middle of the second sleeve, and a second elastic element supporting the valve block is provided on one side of the valve ring; The end of the second sleeve is provided with a third elastic element that supports the valve ring. The second sleeve is connected to the first sleeve, and initially the valve block and the fixing member abut against each other to block the second sleeve.

[0013] Preferably, the upper winding roller is movably connected to the slider, and the lower winding roller is fixedly connected to the slider.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention involves lowering a ship's cable using a winch. The cable is hooked into a slot on a second docking component. The winch then winds up the traction rope, which, under the combined action of the winch and the traction rope, passes through a first through-hole into the support frame. Since the traction rope is initially wound around the outside of the winding assembly, continuous winding pulls the ship's cable around the outside of the winding assembly, securing it in place. This process avoids the traditional figure-eight method of manual cable laying, where the ship must manually untangle the figure-eight knots layer by layer and loosen the stop knots when leaving port. This reduces manual labor and avoids risks such as cable breakage and rebound, personnel falling into the water, or limb injuries, ensuring the safety of the ship when docking. This invention uses a traction rope to guide the ship's cable through the support of the upper winding roller and the lower winding roller, and then through the space between the two winding rollers. The winding rollers fix the ship's cable. When the ship is subjected to the action of waves, the cable is pulled. At this time, the action of the cable is applied to the two winding rollers. Since the cable passes around the outside of the two winding rollers, the winding rollers move relative to each other along the vertical groove through the slider. The pressure blocks on the opposite surfaces of the two winding rollers clamp the ship's cable between the two winding rollers, thereby improving the fixing effect of the ship's cable. This invention utilizes a valve block that, under the action of the second and third elastic elements, abuts against a fixed element, sealing the first and second sleeves and ensuring a sealed state. This allows the distance between the two winding rollers to ensure the traction rope can pass normally between them. The ship's cable is hooked into a slot on the first docking member. The winch winds up the traction rope, pulling it around the winding rollers sequentially. As the cable passes over the winding rollers, the first docking member abuts against the transmission frame, and the diameter of the second through hole is smaller than the outer diameter of the first docking member. The first docking member pushes the transmission frame, guide rod, and valve block to move, causing the valve block to disengage from the fixed element. The ship, affected by waves, sways, which acts on the cable. The tension of the cable pulls the two winding rollers and the pressure block relative to each other, thus clamping the ship's cable between the two winding rollers. Attached Figure Description

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0018] like Figures 1 to 9 As shown, the present invention provides an anchoring device for a ship, including a support frame 1, and further comprising: Winch 5 is installed inside the support frame 1; The traction assembly 2 has one end wound around the outside of the winch 5; the other end is used to connect to the ship's cable. Winding assembly 3 is disposed inside the support frame 1; The traction assembly 2 includes a traction rope 22 wound around the outside of the winch 5. A first docking member 21 is fixedly installed at the end of the traction rope 22. A frustum transmission member 20 is sleeved inside the first docking member 21. A second docking member 25 is fixedly installed on the side of the frustum transmission member 20. The second docking component 25 has a slot 26 for attaching ship cables; The support frame 1 has a first through hole 24 on its side, and the traction rope 22 passes through the first through hole 24; The traction rope 22 is initially wrapped around the outside of the winding assembly 3; The ship's cable is attached to the slot 26 on the second docking member 25, and the traction rope 22 is wound up by the winch 5. Under the action of the traction rope 22, the ship's cable is wrapped around the outside of the winding assembly 3.

[0019] After the ship docks, the ship lowers the cable by casting the support frame 1 to the port shore. The ship cable is hooked into the slot 26 on the second docking part 25. The traction rope 22 is wound up by the winch 5. The ship cable passes through the first through hole 24 and enters the interior of the support frame 1 under the action of the winch 5 and the traction rope 22. Since the traction rope 22 is initially wrapped around the outside of the winding assembly 3, by continuously winding the traction rope 22, the ship cable is pulled to wrap around the outside of the winding assembly 3. The winding assembly 3 fixes the ship cable. Conversely, when a ship departs from port, the cable is retrieved by the winch on the ship, while the winch 5 continuously releases the cable. The cable is retrieved by the winch on the ship, and at the same time, the traction rope 22 is pulled and wrapped around the outside of the winding assembly 3, so that the cable of the berthing ship can be fixed in a cyclical manner.

[0020] This process avoids the traditional manual cable laying method of using the figure-eight staking method. When the ship leaves the port, the figure-eight entanglement needs to be manually untied layer by layer and the stop knot needs to be loosened. This reduces manual operation and avoids risks such as cable breakage and rebound, personnel falling into the water or limb entanglement, thus ensuring the safety of the ship when it docks.

[0021] like Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, the first docking member 21 is provided with a first elastic member 27 that supports the frustum transmission member 20, and the first docking member 21 is provided with a protruding member 28. A magnet 29 is fixedly mounted on the outside of the frustum transmission component 20; The outer diameter of the first mating part 21 is smaller than the inner diameter of the first through hole 24; Under the action of the first elastic member 27, the initial second docking member 25 makes the slot 26 located inside the first docking member 21, and the outer side of the frustum transmission member 20 abuts against the inner wall of the protrusion member 28, so that the outer end of the protrusion member 28 protrudes out of the outer side of the first docking member 21, and the first docking member 21 cannot pass through the first through hole 24 under the action of the protrusion member 28. The second docking member 25 is pulled out, and the ship's cable is hooked onto the slot 26. The protruding part 28 is made of metal. Under the action of the magnet 29, the protruding part 28 retracts into the first docking member 21.

[0022] When the ship docks, the second docking member 25 is pulled to engage the ship's cable with the slot 26. At this time, the frustum transmission member 20 moves outward, and the protruding stop 28, under the action of the magnet 29, adheres to the inclined side of the frustum transmission member 20, thereby retracting into the interior of the first docking member 21. The winch 5 can then wind up the traction rope 22 to pull the ship's cable through the first through hole 24 into the interior of the support frame 1 and wrap around the outside of the winding assembly 3. Conversely, when the ship departs, the winch on the ship pulls the cable in the opposite direction, causing the traction rope 22 to pass through the first through hole 24 and be located outside the support frame 1. The ship's cable disengages from the slot 26 on the second docking member 25, and the second docking member 25 resets under the action of the first elastic member 27 and enters the first docking member 21. The frustum transmission member 20 pushes the protruding stop 28 out of the exterior of the first docking member 21, thus preventing the first docking member 21 from passing through the first through hole 24 into the support frame 1.

[0023] like Figures 2-5 As shown, the winding assembly 3 includes two winding rollers 32, and vertical grooves 34 are symmetrically opened on both sides of the support frame 1. The two winding rollers 32 slide in the vertical grooves 34 through the slider 37. Two winding rollers 32 are provided with pressure blocks 39 on their opposite faces, and support members 33 are fixedly installed on the outside of the two winding rollers 32 in an alternating manner. The support frame 1 is equipped with a guide wheel 23 that limits the traction rope 22; The traction rope 22 is guided by the guide wheel 23 through the support member 33 of the upper winding roller 32, around the support member 33 of the lower winding roller 32, and through the two winding rollers 32.

[0024] The inner wall of the support member 33 is provided with sliding balls, and the outer surface of the winding roller 32 is made of stainless steel to ensure a smooth surface and improve the smoothness of the movement of the traction rope 22 and the ship's cable.

[0025] The ship's cable is attached to the slot 26. The winch 5 winds up the traction rope 22. The traction rope 22 drives the ship's cable, guided by the guide wheel 23, to pass through the support member 33 of the upper winding roller 32 and the support member 33 of the lower winding roller 32 in sequence, and then through the space between the two winding rollers 32. The winding rollers 32 fix the ship's cable. The ship is subjected to the action of the waves, which pulls the cable. At this time, the action of the cable is applied to the two winding rollers 32. Since the cable passes around the outside of the two winding rollers 32, the winding rollers 32 move relative to each other along the vertical groove 34 through the slider 37. The pressure block 39 on the opposite side of the two winding rollers 32 clamps the ship's cable between the two winding rollers 32, thereby improving the fixation effect of the ship's cable. During this process, the swaying force of the ship acts on the winding rollers 32 through the cable and then on the cable, ensuring the stability of the ship.

[0026] like Figure 3 and Figure 5 As shown, the winding assembly 3 also includes a first sleeve 38 fixedly mounted on both sides of the support frame 1. Pistons 35 are fitted on both ends of the first sleeve 38, and the slider 37 is fixedly connected to the pistons 35 through the connecting frame 36. The sealing assembly 4 includes transverse sliding grooves 42 opened on both sides of the support frame 1. A transmission frame 41 is slidably arranged inside the transverse sliding grooves 42. A second through hole 43 is opened in the middle of the transmission frame 41, and the traction rope 22 passes through the second through hole 43. The inner diameter of the second through hole 43 is larger than the outer diameter of the first mating part 21.

[0027] By winding the traction rope 22 with the winch 5, the ship's cable is pulled around the two winding rollers 32 in sequence, so that the first docking part 21 coincides with the second through hole 43, thereby driving the transmission frame 41 to move synchronously through the first docking part 21.

[0028] like Figure 3 and Figure 6 As shown, a second sleeve 44 is fixedly installed in the middle of the first sleeve 38, a fixing member 45 is fixedly installed inside the second sleeve 44, a guide rod 40 is sleeved inside the second sleeve 44, the guide rod 40 is fixedly connected to the transmission frame 41, and a valve block 46 adapted to the fixing member 45 is fixedly installed at the end of the guide rod 40. A valve ring 48 is movably sleeved in the middle of the second sleeve 44, and a second elastic element 47 supporting the valve block 46 is provided on one side of the valve ring 48. The end of the second sleeve 44 is provided with a third elastic element 49 that supports the valve ring 48; The second sleeve 44 is connected to the first sleeve 38, and the initial valve block 46 and the fixing member 45 abut against each other to block the second sleeve 44.

[0029] Initially, due to the action of the second elastic element 47 and the third elastic element 49, the valve block 46 abuts against the fixing element 45, blocking the first sleeve 38 and the second sleeve 44, thus keeping the first sleeve 38 and the second sleeve 44 in a sealed state. This ensures that the distance between the two winding rollers 32 is sufficient to allow the traction rope 22 to pass normally between the two winding rollers 32. The ship's cable is hooked into the slot 26 on the second docking member 25. The winch 5 winds up the traction rope 22, pulling the ship's cable around the winding rollers 38 and 49 in sequence. 2. When the cable passes around the winding roller 32, the first docking part 21 abuts against the transmission frame 41, and the diameter of the second through hole 43 is smaller than the outer diameter of the first docking part 21. The first docking part 21 pushes the transmission frame 41, the guide rod 40 and the valve block 46 to move. The valve block 46 disengages from the fixing part 45. The ship is affected by the waves and sways, which acts on the cable. The cable is tightened and pulls the two winding rollers 32 and the pressure block 39 to move relative to each other. The ship's cable can be clamped by the two winding rollers 32. The gas in the first sleeve 38 enters the second sleeve 44, which pushes the valve ring 48 to move and compresses the third elastic element 49. At this time, the two winding rollers 32 can be guaranteed to move normally relative to each other.

[0030] When the ship leaves the port, the cable valve ring 48 is loosened and moves in the opposite direction under the action of the third elastic element 49. The gas in the second sleeve 44 pushes the two winding rollers 32 to move in the opposite direction, while the first docking part 21 disengages from the transmission frame 41. The fixing part 45 is blocked by the valve block 46, and the ship's cable can move in the opposite direction along the winding rollers 32 and disengage from the inside of the support frame 1.

[0031] like Figure 4 , 5 As shown in Figure 7, the upper winding roller 32 is movably connected to the slider 37, and the lower winding roller 32 is fixedly connected to the slider 37.

[0032] When the ship's mooring line is clamped and fixed by the two winding rollers 32, the ship is subjected to the action of the waves, which keeps the mooring line in a taut state. This causes the upper winding roller 32 to rotate, further enhancing the fixing effect of the two winding rollers 32 on the ship's mooring line.

[0033] Working principle and usage process of this invention: Initially, due to the action of the second elastic element 47 and the third elastic element 49, the valve block 46 abuts against the fixing element 45, blocking the first sleeve 38 and the second sleeve 44, so that the first sleeve 38 and the second sleeve 44 are in a sealed state, thereby ensuring that the distance between the two winding rollers 32 can ensure that the traction rope 22 passes normally between the two winding rollers 32. The ship cable is hooked into the slot 26 on the second docking part 25. The winch 5 winds up the traction rope 22. The traction rope 22 drives the ship cable to pass through the support member 33 of the upper winding roller 32 and the support member 33 of the lower winding roller 32 in sequence under the guidance of the guide wheel 23, and passes between the two winding rollers 32. The first docking part 21 abuts against the transmission frame 41, and the diameter of the second through hole 43 is smaller than the outer diameter of the first docking part 21. The first docking part 21 pushes the transmission frame 41, the guide rod 40 and the valve block 46 to move. The valve block 46 disengages from the fixing part 45. The ship is affected by the waves and sways, which acts on the cable. At this time, the cable acts on the two winding rollers 32. Since the cable passes around the outside of the two winding rollers 32, the winding rollers 32 move relative to each other along the vertical groove 34 through the slider 37. The pressure block 39 on the opposite side of the two winding rollers 32 clamps the ship cable between the two winding rollers 32, thereby improving the ship cable fixing effect. Simultaneously, when the ship's mooring lines are clamped and fixed by the two winding rollers 32, the ship is subjected to the action of waves, which keeps the mooring lines taut. This causes the upper winding rollers 32 to rotate, further enhancing the fixing effect of the two winding rollers 32 on the ship's mooring lines. In this process, the traditional manual mooring method of "8" winding around stakes is avoided. When the ship leaves the port, it is necessary to manually untangle the "8" winding layer by layer and loosen the stop knots. This reduces manual operation and avoids the risks of mooring line breakage and rebound, personnel falling into the water or limb entanglement, etc., ensuring the safety of the ship when it docks.
