Description

Technical Field

[0001] The present application relates to the fields of floating devices and marine technology, and particularly to a fender towing lifting swivel ring for a floating rubber fender, and also to a floating device. Background Art

[0002] A floating rubber fender is a berthing auxiliary device used to absorb the impact energy of floating devices and floating structures when two ships or floating structures are alongside, or for lateral transportation of oil, gas, and goods, preventing hard contact between the two ships or floating structures. The lifting sling is a component provided at the end of the floating rubber fender, and the floating rubber fender is connected to the guy wire, lifting cable, or lashing rope through this swivel.

[0003] ISO 17357-1 2014 provides standardized forms of floating rubber fenders, but there is little mention of this important component, the lifting and towing sling. The lifting slings configured for traditional floating rubber fenders do not have a unified standard, and their forms are diverse, resulting in uneven quality. Unreasonable sling designs affect the use of the fender and even become the weakest link of the entire fender. It does not consider that the fender needs to be semi-immersed in seawater for a long time, making it extremely easy to corrode and break. With low strength, the connection points are often damaged. The sling design is too simple, resulting in the cables tied to it being twisted and entangled. Due to long-term wave impact, the sling is prone to loosening. Summary of the Invention

[0004] Based on this, it is necessary to propose a fender towing lifting swivel ring that can avoid cable twisting and entanglement during use. A floating device is also proposed.

[0006] In some embodiments, the swivel footrest includes a top ring body, a bottom ring body, and a plurality of partition plates. The plurality of partition plates are respectively connected to the top ring body and the bottom ring body and are arranged at intervals along the circumference. An installation position is formed between adjacent partition plates, and the bottom ring body is provided with connection hole positions in each installation position.

[0007] In some embodiments, a self-lubricating bushing is further provided between the rotating shaft and the swivel footrest.

[0011] In some embodiments, the eccentric perforated plate is in the shape of a rectangular plate. In the radial direction of the mounting hole, the distance from the center line of the mounting hole to the first end of the eccentric perforated plate is greater than the distance from the center line of the mounting hole to the second end of the eccentric perforated plate, and the lifting hole is provided between the center line of the mounting hole and the first end of the eccentric perforated plate.

[0012] In some embodiments, the materials of the swivel footrest, the eyeplate rotating member, and the eccentric perforated plate are all duplex stainless steel.

[0013] In some embodiments, the swivel footrest is an integrally formed part; the eyeplate and the rotating shaft are integrally formed parts.

If present, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0031] According to one aspect of the present application, a fender towing lifting swivel is proposed. The fender towing lifting swivel is used to be arranged on a floating rubber inflatable fender and is used when stabilizing and lifting the floating rubber inflatable fender.

[0032] Reference Figures 1 to 3 , Figure 1 is a front view of the fender towing lifting swivel according to an embodiment of the present application; Figure 2 is a side view of the fender towing lifting swivel according to an embodiment of the present application; Figure 3 is a schematic structural view of the eccentric perforated plate in the fender towing lifting swivel according to an embodiment of the present application.

[0033] The fender towing lifting swivel 100 according to an embodiment of the present application includes a swivel footrest 10, an eyeplate rotating member 20, and an eccentric perforated plate 30. The eccentric perforated plate 30 is rotatably arranged between the swivel footrest 10 and the eyeplate rotating member 20.

[0034] As Figures 4 to 7 shown, the swivel footrest 10 is used to be installed at the end of the floating rubber inflatable fender 200 in the length direction, so that the fender towing lifting swivel 100 is arranged on the floating rubber inflatable fender 200. Specifically, a fender chain net 201 is wrapped on the floating rubber inflatable fender 200, and the fender chain net 201 is connected to the swivel footrest 10 through a shackle 202.

[0035] The eyeplate rotating member 20 includes a connected eyeplate 210 and a rotating shaft 220. One end of the rotating shaft 220 is connected to the eyeplate 210, and the other end of the rotating shaft 220 passes through the swivel footrest 10 from one side of the swivel footrest 10 and is provided with an anti-disengagement structure 40. In this way, the swivel footrest 10 and the eyeplate rotating member 20 form a rotating pair, and the eyeplate 210 can rotate relative to the swivel footrest 10. The eyeplate 210 has at least one eyehole 211. The eyehole 211 is used to connect the stabilizing cable 300 on the ship's side, so that the floating rubber inflatable fender 200 can be suspended on the ship's side of the hull 400.

[0036] As Figure 4As shown, the length direction of the floating rubber inflatable fender 200 is along the length direction X of the hull 400. At both ends of the floating rubber inflatable fender 200 in the length direction, the fender towing lifting and rotating rings 100 of the present application are respectively provided. In this way, both ends of the floating rubber inflatable fender 200 in the length direction are respectively connected to the ship's side of the hull 400 through the stabilizing cables 300. As Figure 6 shown, when the floating device is docked, the floating rubber inflatable fender 200 is located between the hull 400 and other floating bodies 500.

[0037] Among them, the eccentric perforated plate 30 is provided with a mounting hole 310 and a lifting hole 320. The mounting hole 310 is rotationally matched with the rotating shaft 220, so that the eccentric perforated plate 30 is arranged between the eye plate 210 and the swivel bracket 10. The lifting hole 320 is used to cooperate with the hook of the crane, so that the crane can lift the floating rubber inflatable fender 200.

[0038] As Figure 1 and Figure 3 shown, in the radial direction of the mounting hole 310, with the center line of the mounting hole 310 as the boundary, the weights of the eccentric perforated plate 30 on both sides of the mounting hole 310 are not equal, and the lifting hole 320 is arranged on the side with the greater weight. That is to say, the eccentric perforated plate 30 is configured to have an eccentric weight distribution.

[0039] In this embodiment, as Figure 3 shown, the eccentric perforated plate 30 is in the shape of a rectangular plate. In the radial direction of the mounting hole 310, the distance A from the center line of the mounting hole 310 to the first end of the eccentric perforated plate 30 is greater than the distance B from the center line of the mounting hole 310 to the second end of the eccentric perforated plate 30, and the lifting hole 320 is arranged between the center line of the mounting hole 310 and the first end of the eccentric perforated plate 30. The above distance A is greater than the distance B, and the mass of the eccentric perforated plate 30 on the left side of the center line of the mounting hole 310 is greater than the mass of the eccentric perforated plate 210 on the right side of the center line of the mounting hole 310. It is easy to understand that the weights of the eccentric perforated plate 30 on both sides of the mounting hole 310 are not equal, and are not limited to the above examples. For example, it can also be that the thicknesses of the eccentric perforated plate 30 on both sides of the mounting hole 310 are different.

[0040] Refer to Figures 4 to 7, the fender towing lifting swivel ring 100 is installed at the end of the floating rubber inflatable fender 200 in the length direction. The length direction of the floating rubber inflatable fender 200 is consistent with the length direction X of the hull 400. The axial directions of the rotating shaft 220 and the mounting hole 310 are both substantially consistent with the length direction of the floating rubber inflatable fender 200 and the length direction of the hull 400. The rotation plane of the eccentric perforated plate 30 is parallel to the gravity direction Z. When it is necessary to lift the floating rubber inflatable fender 200 by a crane, the staff takes a workboat and sails to the vicinity of the floating rubber inflatable fender 200, hangs the hook of the crane on the lifting hole 320, and then turns over the eccentric perforated plate 30 to lift it.

[0041] In this embodiment, the weights on both sides of the eccentric perforated plate 30 in the mounting hole 310 are not equal, and the lifting hole 320 is arranged on the side with the larger weight. At the same time, the eccentric perforated plate 30 is also rotationally matched with the rotating shaft 220. When the lifting hole 320 is not engaged with the hook of the crane, under the action of gravity, the lifting hole 320 is always located below the rotating shaft 220 and the mounting hole 310.

[0042] Therefore, when it is necessary to lift the floating rubber inflatable fender 200 by a crane, it is convenient for the staff to operate when hanging the hook of the crane on the lifting hole 320. In addition, during the process of lifting and turning over the eccentric perforated plate 30, since the eccentric perforated plate 30 is configured with an eccentric weight distribution, the force on the eccentric perforated plate 30 is always consistent with the gravity direction, so that it will not affect the stabilizing cable 300 and the fender chain net 201, and can avoid the twisting and entanglement of the stabilizing cable 300 and the fender chain net, prevent uneven local stress on the stabilizing cable 300, delay the material aging, and extend the service life of the stabilizing cable 300.

[0043] The fender towing lifting swivel ring 100 of the present application is provided with an eccentric perforated plate 30, which is specifically used for lifting by a crane, and does not need to use the eye hole 211 connected to the stabilizing cable 300 for lifting, reducing the requirements for the specifications, strength, etc. of the eye hole 211, and also facilitating the hook setting and cooperation with the hook; and because the eccentric perforated plate 30 is configured with an eccentric weight distribution, the force on the eccentric perforated plate 30 is always consistent with the gravity direction during the lifting process, so that it will not affect the stabilizing cable 300 and the fender chain net 201, and can avoid the twisting and entanglement of the cable.

[0044] Reference Figure 1 , Figure 2 , Figure 5 and Figure 7 , in some embodiments, the swivel footrest 10 includes a top ring body 110, a bottom ring body 120, and a plurality of partition plates 130. The plurality of partition plates 130 are respectively connected to the top ring body 110 and the bottom ring body 120 and are arranged at intervals in the circumferential direction. An installation position is formed between adjacent partition plates 130, and the bottom ring body 120 is provided with a connection hole position 121 in each installation position.

[0045] The top ring body 110 and the bottom ring body 120 are arranged at intervals in the axial direction of the rotating shaft 220 and are connected as a whole through the dividing plate. The top ring body 110 is rotatably matched with the rotating shaft 220. The multiple dividing plates form multiple installation positions in the circumferential direction of the bottom ring body 120. Each installation position is used to connect two shackles 202, which play the role of limiting, distributing, combing, and fender chain ring net.

[0046] refer to Figure 1 and Figure 2 A self-lubricating sleeve 50 is also provided between the rotating shaft 220 and the swivel bracket 10. Specifically, the self-lubricating sleeve 50 is provided between the top ring body 110 and the rotating shaft 220. The solid lubricant contained in the sleeve material of the self-lubricating sleeve 50 and its inner surface reduces friction and wear of the rotating shaft 220, ensuring smooth and unobstructed rotation of the ring bracket and regular replacement.

[0047] Furthermore, if Figure 1 and Figure 2 As shown, the anti-drop structure 40 includes a locking nut 410 installed on the other end of the rotating shaft 220. The locking nut 410 is threadedly matched with the other end of the rotating shaft 220, and the locking nut 410 is abutted against the top ring body 110, thereby preventing the eye plate rotating member 20 from falling off the swivel tripod 10.

[0048] Furthermore, the anti-slip structure 40 also includes a safety pin 420 that is simultaneously penetrated through the locking nut 410 and the rotating shaft 220. The safety pin 420 penetrates the locking nut 410 and the rotating shaft 220 along the radial direction of the rotating shaft 220 to prevent the locking nut 410 from loosening, thereby preventing the fender towing and lifting rotating ring 100 from loosening during long-term seawater flushing.

[0049] refer to Figure 3 The eccentric multi-hole plate 30 is provided with a lashing hole 330 on the side with a smaller weight. The number of the lashing hole 330 is at least one. The lashing hole 330 is used as a reserved hole for lashing ropes, and is used to fix the floating rubber inflatable fender 200 on the deck by lashing ropes after the floating rubber inflatable fender 200 is hoisted on the deck.

[0050] In the present application, the materials of the swivel bracket 10, the eye plate rotating member 20 and the eccentric multi-hole eye plate 30 are all duplex stainless steel. For example, the materials of the swivel bracket 10, the eye plate rotating member 20 and the eccentric multi-hole eye plate 30 are all 00Cr22Ni5Mo3N.

[0051] During the use of the fender towing lifting swivel ring 100, it is semi-immersed in seawater for a long time, subjected to various forces, and the influencing factors such as seawater corrosion and microbial corrosion also need to be considered simultaneously. Therefore, in this application, the materials of the swivel bracket 10, the eyeplate rotating member 20, and the eccentric perforated eyeplate 30 are all duplex stainless steel. Compared with carbon steel and ordinary stainless steel, duplex stainless steel has the material characteristics of high strength and excellent corrosion resistance in chloride-rich media, which can match the offshore engineering use scenario of the floating device of the fender.

[0052] In the embodiment of this application, the swivel bracket 10 is an integrally formed part; the eyeplate 210 and the rotating shaft 220 are integrally formed parts. The eyeplate rotating member 20 makes the rotating shaft 220 and the eyeplate 210 into a whole, and like the swivel bracket 10, an integral forming process is adopted. The welds are reduced, the weak points are reduced, the swivel structure is more uniform, and the impact resistance and fatigue resistance are more remarkable. The continuity of the material molecules is better, and the strength and durability are higher.

[0053] Reference Figures 4 to 7 , the second aspect of this application also proposes a floating device. The floating device includes: a hull 400; a floating rubber inflatable fender 200 provided on one side of the hull 400 of the ship. The floating rubber inflatable fender 200 is provided with the fender towing lifting swivel ring 100 of any of the foregoing embodiments at at least one end in the length direction X of the hull 400. The eyeplate 210 is connected to the ship's side through a stabilizing cable 300, and the rotation plane of the eccentric perforated eyeplate 30 is parallel to the gravity direction.

[0054] Specifically, a plurality of floating rubber inflatable fenders 200 are provided on both the left and right sides of the hull 400. The plurality of floating rubber inflatable fenders 200 on each side are arranged along the length direction X of the hull 400, and the length direction of each floating rubber inflatable fender 200 itself is consistent with the length direction X of the hull 400. Each floating rubber inflatable fender 200 is provided with the fender towing lifting swivel ring 100 of this application at both ends in its own length direction.

[0055] The fender towing lifting swivel ring 100 is installed at the end of the floating rubber inflatable fender 200 in the length direction. The length direction of the floating rubber inflatable fender 200 is consistent with the length direction X of the hull 400. The axial directions of the rotating shaft 220 and the mounting hole 310 are both approximately consistent with the length direction of the floating rubber inflatable fender 200 and the length direction X of the hull 400. Therefore, the rotation plane of the eccentric perforated eyeplate 30 is parallel to the gravity direction. When it is necessary to lift the floating rubber inflatable fender 200 by a crane, the staff takes a workboat and sails to the vicinity of the floating rubber inflatable fender 200, hangs the hook of the crane on the lifting hole 320, and then flips the eccentric perforated eyeplate 30 to lift it.

[0056] The floating rubber fender 200 of the floating device of the present application is provided with a fender towing lifting rotating ring 100. The fender towing lifting rotating ring 100 is provided with an eye plate 210, and the eye plate 210 has at least one eyehole 211. The eyehole 211 is used to connect the stabilizing cable 300 on the ship's side, so that the floating rubber fender 200 can be suspended on the ship's side. The fender towing lifting rotating ring 100 is provided with an eccentric multi-hole eye plate 30, which is specifically used for the hoisting of the crane. It is not necessary to use the eyehole 211 connected to the stabilizing cable 300 for hoisting, reducing the requirements for the specifications and strength of the eyehole 211, and also facilitating the hook setting and cooperation with the lifting hook. And because the eccentric multi-hole eye plate 30 is configured with a weight eccentric distribution, the force on the eccentric multi-hole eye plate 30 is always consistent with the direction of gravity during the hoisting process, thus not affecting the stabilizing cable 300 and the fender chain net 201, being able to avoid the twisting and entanglement of the cable, preventing uneven local stress on the stabilizing cable 300, delaying the aging of the material, and extending the service life of the stabilizing cable 300.

[0057] Finally, it should be noted that the technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0058] The above-described embodiments only represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limitations on the scope of the patent application. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
