[0041] Reference below Figures 1-8 A mooring wire rope righting structure according to an embodiment of the present invention is described.

[0042] like Figures 1-8 As shown, the mooring wire rope righting structure includes a floating platform 100, which includes a floating platform deck 120 and a floating platform side 110. The floating platform side 110 is provided with a working platform 130. In this embodiment, the floating platform side is provided with multiple working platforms 130, which are used to fix fixed components on the floating platform side 110.

[0043] The system includes a chain pulley mechanism 210, located on the side of the floating platform deck 120, for retracting and deploying the anchor wire rope 300. A chain guide drum mechanism 220, located on the working platform 130 on the side of the floating platform 110, connects one end of the anchor wire rope 300 to the anchor chain 230, which then passes through the chain guide drum mechanism 220. A wire rope straightening mechanism 500, located between the chain pulley mechanism 210 and the chain guide drum mechanism, has one end hinged to the side of the floating platform 110 and the other end in contact with the anchor wire rope 300 to compensate for bouncing, deviation, and derailment of the anchor wire rope 300. The chain guide drum mechanism 220 is located on the corresponding working platform 130, and the anchor chain 230 is raised and lowered within the chain guide drum mechanism 220.

[0044] Specifically, a chain pulley mechanism 210 is positioned above the platform deck 120 of the floating platform 100, and a work platform 130 is designed and arranged on the side 110 of the floating platform. In the mooring system of the floating platform 100, a chain guide drum mechanism 220 is designed and arranged on the work platform 130. An anchor chain 230 is connected to the anchor wire rope 300 and passes through the chain guide drum mechanism 220 and the chain pulley mechanism 210, achieving normal and smooth up and down transmission of the anchor chain 230, thereby completing a smooth anchor retracting and deploying process and ensuring the normal function of the mooring system of the floating platform 100.

[0045] The mooring wire rope righting structure of this embodiment ensures that the anchor wire rope 300 maintains its optimal working condition even in severe wind and wave conditions at sea, when the floating platform 100 sways, and prevents the anchor wire rope 300 from deviating from its groove, thereby ensuring the safe mooring of the floating platform 100 at sea. Specifically, a wire rope righting mechanism 500 is arranged between the chain guide wheel mechanism 210 and the chain guide drum mechanism 220, and the wire rope righting function is achieved by the lateral support cylinder 400. The transmission of the anchor wire rope 300 requires crossing the sprocket mechanism 210 and the chain guide drum mechanism 220. Due to unstable sea waves and during mooring operations, the anchor wire rope 300 often jumps and deviates, causing the anchor wire rope 300 to derail in the sprocket mechanism 210 and the chain guide drum mechanism 220. This also causes the anchor chain 230 to jump, deviate, and derail, resulting in mooring failure and affecting the mooring of the floating platform 100. The design and arrangement of the wire rope righting mechanism 500 compensates for the problems of jumps, deflection, and derailment, can stably maintain the anchor wire rope 300, and effectively eliminate the safety risks of the mooring design of the floating platform 100.

[0046] like Figure 2 and Figure 3 As shown, the distance from the end of the wire rope righting mechanism 500 to the anchor wire rope 300 is equal to the distance from the chain guide drum mechanism 220 to the side 110 of the floating platform.

[0047] Specifically, the distance L1 between the anchor wire rope 300 at the chain guide drum mechanism 220 and the side 110 of the floating platform, and the distance L between the anchor wire rope 300 at the chain guide wheel mechanism 210 and the side 110 of the floating platform, are L=L1 under normal optimal conditions, and the design value of L is about 1 to 2 meters. The lateral support cylinder 400 provides instant lateral support for the anchor wire rope 300 to ensure that L=L1.

[0048] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, it also includes a lateral support cylinder 400, one end of which is hinged to the side 110 of the floating platform, and the other end is hinged to the middle of the wire rope righting mechanism 500, for controlling the up and down rotation of the wire rope righting mechanism 500.

[0049] Specifically, the lateral support cylinder 400 provides immediate lateral support for the anchor wire 300, ensuring L = L1. One end of the wire rope straightening mechanism 500 is fixed to the side structure 110 of the floating platform. During operation, its other (outer) end supports the anchor wire 300, with the lower center portion resting on the corresponding work platform 130. The upper center portion is connected to the lateral support cylinder 400, which pulls it upward and downward, adjusting the distance L to maintain L = L1.

[0050] The outer end limit width b of the wire rope straightening mechanism 500 is designed to be 200 to 300 mm, which limits the horizontal sliding of the anchor wire rope 300. The sliding range b, that is, it also limits the sliding range b of the anchor wire rope 300 between the guide chain wheel mechanism 210 and the guide chain drum mechanism 220, so as to achieve the purpose of limiting its sliding out of the groove in the guide chain wheel mechanism 210 and the guide chain drum mechanism 220 respectively.

[0051] In some embodiments of the present invention, Figure 5 As shown, the base of the guide sprocket mechanism 210 is provided with a cylinder suspension connection plate 650, and the middle portion of the lateral support cylinder 400 is connected to the cylinder suspension connection plate 650 via a connecting wire rope 670. A cylinder connection plate 660 is provided on the side 110 of the floating platform, and one end of the lateral support cylinder 400 is hinged to the cylinder connection plate 660.

[0052] Specifically, the upper end of the lateral support cylinder 400 is movably connected to the side 110 of the floating platform via a cylinder connecting plate 660. The cylinder suspension connecting plate 650 is welded to the side 110 of the floating platform. The middle of the lateral support cylinder 400 is connected to the cylinder suspension connecting plate 650 by a connecting wire rope 670 to secure the lateral support cylinder 400 to prevent it from falling.

[0053] In some embodiments of the present invention, Figure 6-Figure 8As shown, the wire rope righting mechanism 500 adopts a double main arm combination structure, each main arm includes a righting arm web 511, and the two righting arm webs 511 are connected and fixed by a righting arm connecting plate 513. The top and bottom of the two righting arm webs 511 are provided with righting arm panels 512.

[0054] The centralizing arm web 511, the centralizing arm panel 512 and the centralizing arm connecting plate 513 are made of steel plates, the thickness of which is determined according to the design, and the material is Q235.

[0055] Further, if Figure 6-Figure 8 As shown, a rolling pulley shaft 522 is provided between the two righting arm webs 511 , and a rolling pulley 521 is rotatably sleeved on the rolling pulley shaft 522 .

[0056] Specifically, the centralizing arm connecting plate 513 is connected and fixed to the centralizing arm webs 511 (i.e., the main arms) on both sides. Rolling pulleys 521 are provided at the outer ends of the main arms on both sides and roll through the rolling pulley shaft 522. The rolling pulleys 521 can guide the sliding of the anchor wire rope 300. When the rolling pulleys 521 support the anchor wire rope 300, the anchor wire rope 300 rolls up and down, which can effectively reduce friction damage to the anchor wire rope 300 during operation.

[0057] The rolling pulley 521 and rolling pulley shaft 522 are made of round steel, with a diameter determined by the design and made of Q235 steel. The height of the centralizing arm web 511 is determined by the design and is approximately 100-200 mm. The length of the centralizing arm web 511 is determined by the design and is approximately 1000-2000 mm. In a dual-boom configuration, the distance b1 between the centralizing arm webs 511 is the distance between the two main booms. The length of the rolling pulley 521 is less than b1, with a design value of b1 of 200-300 mm.

[0058] In some embodiments of the present invention, Figure 5 As shown, a centralizing arm shaft connecting plate 611 is provided on the side 110 of the floating platform, and the centralizing arm web 511 is connected to the centralizing arm shaft connecting plate 611 via a centralizing arm shaft 612 .

[0059] One end of the wire rope righting mechanism 500 is fixed to the side of the floating platform 110, and the end righting arm shaft connecting plate 611 is welded and fixed to the side of the floating platform 110. The wire rope righting mechanism 500 can rotate around the righting arm shaft 612, and its other end supports the anchor wire rope 300.

[0060] In some embodiments of the present invention, Figure 4 and Figure 5As shown, a centralizing arm fixing connecting plate 620 is provided on the side of the centralizing arm panel 512 close to the side 110 of the floating platform, and a fixing connecting plate 640 is provided on the side 110 of the floating platform. The fixing connecting plate 640 and the centralizing arm fixing connecting plate 620 are detachably connected by a pin.

[0061] Specifically, when the mooring system of the floating platform 100 is in a resting state, that is, when the anchor wire rope 300 is in a resting state, the wire rope righting mechanism 500 is not in operation. The lateral support cylinder 400 rotates upward, driving the wire rope righting mechanism 500 to rotate upward, and the outer end of the wire rope righting mechanism 500 is separated from the anchor wire rope 300. The fixed connecting plate 640 can fix the wire rope righting mechanism 500 to prevent it from falling.

[0062] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, a centralizing arm oil cylinder connecting plate 630 is provided in the middle of the centralizing arm panel 512 , and the centralizing arm oil cylinder connecting plate 630 is hinged to the lateral supporting oil cylinder 400 .

[0063] Furthermore, a centralizing arm bottom connecting plate 680 is provided on the other side of the centralizing arm panel 512 corresponding to the centralizing arm cylinder connecting plate 630. A working platform 130 is provided below the wire rope centralizing mechanism 500, and the centralizing arm bottom connecting plate 680 is located on the surface of the working platform 130.

[0064] Specifically, the bottom connecting plate 680 of the straightening arm corresponds to the force point connected to the lateral support cylinder 400, is connected and falls on the working platform 130, supports and offsets the force exerted on the wire rope straightening mechanism 500 during the telescopic movement of the lateral support cylinder 400, and ensures that the force of the wire rope straightening mechanism 500 is balanced.
