[0002] With the increasing maturity and wide application of offshore oil and gas development technology, the floating facility market is showing a booming trend, and the demand for related supporting floating devices is growing. Since the floating device and the alongside ship are prone to hard contact during the horizontal transportation of oil, gas, cargo and the like, the floating facility is usually equipped with inflatable rubber fenders to play a protective role, and therefore a series of operations such as deployment, recovery, storage, maintenance and replacement of the fenders need to be completed.

[0041] Referring to Figures 1 to 8 As shown in the structural schematic diagram of the fender hanger device 10 in an embodiment of the present application, the fender hanger device 10 provided by the embodiment of the present application includes a mounting base 100, a hanger mechanism 200 and a driving mechanism 300. The fender hanger device 10 can be arranged on a floating facility and used for deploying and recovering the inflatable rubber fender 20. The fender hanger device 10 is convenient and flexible in transferring the fender 20.

[0042] Specifically, the mounting base 100 serves as a bearing base of the entire fender hanger device 10 and can be installed at a scene such as a deck of a floating facility. The mounting base 100 can integrate all components including the hanger mechanism 200 and the driving mechanism 300, so that the fender hanger device 10 has a compact structure and high space utilization rate. Moreover, the fender hanger device 10 can be pre-assembled and pre-tested before leaving the factory, thereby reducing the workload of transportation, installation and debugging.

[0043] The hanger mechanism 200 includes a first hoist arm 210 and a second hoist arm 220. For example, the first hoist arm 210 and the second hoist arm 220 can have a hollow structure, which not only reduces the weight of the hoist arms 210 and 220 but also ensures the bearing strength. The first hoist arm 210 and the second hoist arm 220 are respectively rotatably connected to the mounting base 100 through a pin shaft, so that the first hoist arm 210 and the second hoist arm 220 can be used for hoisting the fender 20 to complete a series of operations such as deployment, recovery, storage, maintenance and replacement of the fender 20.

[0044] The driving mechanism 300 is used to provide power for the hanger mechanism 200, and the driving mechanism 300 comprises a first driving member 310 and a second driving member, which are respectively arranged on the mounting base 100. The first driving member 310 is in driving connection with the first boom 210 and is configured to drive the first boom 210 to rotate relative to the mounting base 100. The second driving member is in driving connection with the second boom 220 and is configured to drive the second boom 220 to rotate relative to the mounting base 100. For example, the first driving member 310 and the second driving member can be selected as hydraulic cylinders, which are respectively hinged to the mounting base 100 and the boom. In addition, the driving mechanism 300 can further comprise a hydraulic unit 330, a control box 340, and a pump set 350. An operator issues an instruction through the control box 340 to control the hydraulic unit 330 to act, and the hydraulic unit 330 outputs pressure oil to the hydraulic cylinders through the pump set 350 and controls the flow direction of the pressure oil to realize the extension and retraction of the hydraulic cylinders, so as to respectively drive the first boom 210 and the second boom 220 to rotate relative to the mounting base 100. Of course, in other alternative embodiments, the first driving member 310 and the second driving member can also be selected as other driving devices such as electric push rods, as long as the actual driving requirements can be met.

[0045] Through the above structural design, the fender hanger device 10 drives the first boom 210 and the second boom 220 to rotate through the first driving member 310 and the second driving member respectively, that is, the first boom 210 and the second boom 220 are used to hoist the fender 20, so as to realize the transfer of the fender 20 inside and outside the fender, the lowering and recovery of the fender 20, and the operation is convenient, which is beneficial to improve the operation efficiency. Moreover, since the first boom 210 and the second boom 220 are independently driven by the first driving member 310 and the second driving member respectively, the rotation angles of the first boom 210 and the second boom 220 can be adjusted individually. For example, when deploying the fender 20, the first boom 210 can be controlled to rotate out of the fender to a preset operation position, and the second boom 220 remains in the fender to assist in stabilization. For another example, when recovering the fender 20, one of the booms can be individually rotated to fine-tune the position of the fender 20, so as to avoid the collision between the fender 20 and the floating facility. This independent control mode makes the fender hanger device 10 adapt to the distance between different floating facilities and the alongside ship, and the operation is more flexible, which is beneficial to efficiently and accurately complete various operation requirements of the fender 20.

[0046] Further, referring to Figures 3 to 5As shown, in some embodiments, the first boom 210 comprises a first support arm 211, a first folding arm 212 and a first locking member 213. The bottom end of the first support arm 211 is rotatably connected to the mounting base 100 about a first rotation axis L1, for example, the first support arm 211 can be rotatably connected to the mounting base 100 through a pin shaft and bearing cooperation, at this time the corresponding pin shaft center line is the first rotation axis L1. The bottom end of the first folding arm 212 is rotatably connected to the top end of the first support arm 211 about a second rotation axis L2, for example, the first folding arm 212 can be rotatably connected to the first support arm 211 through a pin shaft and bearing cooperation, at this time the corresponding pin shaft center line is the second rotation axis L2. The first locking member 213 is connected to the first support arm 211 and the first folding arm 212 respectively, and is configured to lock or release the first support arm 211 and the first folding arm 212. When the fender hanger device 10 is transported or transferred, the first locking member 213 can be released, and the first folding arm 212 is folded to the side of the first support arm 211 about the second rotation axis L2. After folding, the overall length of the first boom 210 is greatly shortened, the occupied space is reduced, so that the first folding arm 212 can be folded and transported as a whole, without the need to disassemble the first boom 210 from the mounting base 100. Before operation, only the first folding arm 212 needs to be unfolded and locked by the first locking member 213 to lock the first folding arm 212 and the first support arm 211, so as to restore the operation length of the first boom 210, which is convenient for installation and transportation. Moreover, when the fender 20 hanger is in a non-operation state, the first boom 210 can also be folded and stored, which is especially suitable for the storage needs of narrow space in the fender 20 of the floating facility.

[0047] It should be noted that in some embodiments, the structure of the second boom 220 can be the same as that of the first boom 210, and the difference between the second boom 220 and the first boom 210 is that they are driven by independent first driving member 310 and second driving member respectively. Therefore, in the following embodiments, only the first boom 210 is taken as an example for introduction, but it should be understood that the cooperation relationship between the second boom 220 and the cable mechanism 400 and other components in the following embodiments can be the same as that between the first boom 210 and the cable mechanism 400 and other components.

[0048] Optionally, referring to Figure 3 and Figure 5As shown, in some embodiments, the first rotation axis L1 is parallel to the second rotation axis L2. For example, the first rotation axis L1 is determined by a pin shaft that rotatably connects the mounting base 100 with the first support arm 211, and the second rotation axis L2 is determined by a pin shaft that rotatably connects the first support arm 211 with the first folding arm 212. It should be understood that if the first rotation axis L1 and the second rotation axis L2 are not parallel, a lateral component force will be generated when the first folding arm 212 rotates relative to the first support arm 211, resulting in resistance and jamming during rotation, causing the folding to be not smooth. In the present embodiment, the first rotation axis L1 and the second rotation axis L2 are parallel, so that when the first folding arm 212 rotates around the first support arm 211, there is no lateral component force, which can reduce the rotation resistance, so as to complete the folding and unfolding operation of the first boom 210, while reducing the wear during rotation of the first boom 210, prolonging the service life and reducing the maintenance cost.

[0049] Further, referring to Figures 3 to 5 As shown, in some embodiments, the first support arm 211 includes a support segment 2111 and a first connecting segment 2112, and the support segment 2111 is rotatably connected to the mounting base 100 around the first rotation axis L1. For example, the support segment 2111 and the first connecting segment 2112 are integrally formed to ensure the strength of the first support arm 211. Also, the first folding arm 212 includes a second connecting segment 2121 and a folding segment 2122, and the second connecting segment 2121 is rotatably connected to the first connecting segment 2112 around the second rotation axis L2. For example, the second connecting segment 2121 and the folding segment 2122 are integrally formed to ensure the strength of the first folding arm 212. The first locking member 213 is connected to the first connecting segment 2112 and the second connecting segment 2121, respectively, and is configured to lock or release the first connecting segment 2112 and the second connecting segment 2121. The first connecting segment 2112 is connected to the support segment 2111 and forms a first included angle a, and the folding segment 2122 is connected to the second connecting segment 2121 and forms a second included angle β, the second included angle β and the first included angle a are obtuse angles, and the openings of the second included angle β and the first included angle a are towards the same side of the first support arm 211. Due to the openings of the second included angle β and the first included angle a being towards the same side, the first boom 210 assumes a posture of bending to one side after being unfolded, so as to adapt to the shape of the fender 20. Thus, when the first boom 210 drives the fender 20 to turn out from the side to the outside and to be retracted from the outside to the side, the fender 20 will not interfere with the first boom 210, and the fender 20 can maintain a sufficient distance from the hull plate of the alongside ship to avoid scratching the hull plate.

[0050] Optionally, in some embodiments, the first driving member 310 is connected to the joint of the support segment 2111 and the first connecting segment 2112, on the one hand, to make the first driving member 310 connected with the support segment 2111 and the mounting base 100 to form a triangular structure, to improve the stability; on the other hand, to make the force output by the first driving member 310 directly acting on the first connecting segment 2112, so as to drive the first folding arm 212 connected with the first connecting segment 2112 to move, thereby facilitating the hoisting of the fender 20.

[0051] Further, in some embodiments, the first connecting segment 2112 and the second connecting segment 2121 are connected and locked along the same straight line. Specifically, referring to Figure 3 It is shown that the first connecting segment 2112 and the second connecting segment 2121 are respectively provided in a straight line shape, and when the first connecting segment 2112 and the second connecting segment 2121 are locked by the first locking member, the first connecting segment 2112 and the second connecting segment 2121 as a whole extend along the same straight line. It should be understood that if the first connecting segment 2112 and the second connecting segment 2121 are not locked along the same straight line, the gravity of the fender 20 during hoisting will generate an additional bending moment at the joint of the first connecting segment 2112 and the second connecting segment 2121, which is easy to cause deformation or even cracking of the joint. In the embodiment, when the first connecting segment 2112 and the second connecting segment 2121 extend along the same straight line, the gravity of the fender 20 is transmitted along the axis of the first connecting segment 2112 and the second connecting segment 2121, without additional bending moment, which can improve the carrying capacity of the first hoisting arm 210 and ensure the hoisting stability.

[0052] Further, referring to Figures 3 to 5 It is shown that in some embodiments, the first locking member 213 includes a rotating shaft 2131 and a lock bolt 2132. The rotating shaft 2131 is a cylindrical structure, and the rotating shaft 2131 has a second rotation axis L2, i.e. the central axis of the rotating shaft 2131. The rotating shaft 2131 is arranged at the opening side of the first support arm 211 and the first folding arm 212, wherein the opening side is the side of the first support arm 211 where the opening of the first included angle a is directed, i.e. the side of the first folding arm 212 where the opening of the second included angle β is directed. Referring to Figure 3 It is shown that the opening side is the left side in the view angle. The rotating shaft 2131 is connected to the first connecting segment 2112 and the second connecting segment 2121, for example, the rotating shaft 2131 can be connected to the first connecting segment 2112 and the second connecting segment 2121 through two ear plates, so that the second connecting segment 2121 can rotate relative to the second connecting segment 2121 around the rotating shaft 2131.

[0053] The lock bolt 2132 is configured to pass through and fix the first connecting segment 2112 and the second connecting segment 2121 when the first connecting segment 2112 and the second connecting segment 2121 are connected. For example, the lock bolt 2132 can include a bolt, and the number of bolts can be multiple. The end of the first connecting segment 2112 connected with the second connecting segment 2121 is provided with a flange structure, and the end of the second connecting segment 2121 is also provided with a corresponding flange structure. The bolts are sequentially passed through the through holes on the flange structures of the first connecting segment 2112 and the second connecting segment 2121 and are tightened, so that the first connecting segment 2112 and the second connecting segment 2121 are locked. Conversely, the bolts are removed, so that the first connecting segment 2112 and the second connecting segment 2121 are loosened, and the first connecting segment 2112 and the second connecting segment 2121 are unlocked.

[0054] Therefore, the cooperation of the rotating shaft 2131 and the lock bolt 2132 can improve the locking reliability, ensure that the first connecting segment 2112 and the second connecting segment 2121 can withstand the vibration and impact load during the operation of the first lifting arm 210, and ensure the structural safety of the first lifting arm 210 during the operation. Moreover, since the rotating shaft 2131 is arranged at the opening side of the first supporting arm 211 and the first folding arm 212, when the first folding arm 212 rotates around the rotating shaft 2131, the second connecting segment 2121 of the first folding arm 212 is not blocked by the first connecting segment 2112 of the first supporting arm 211, so the rotation range of the first folding arm 212 is sufficient to facilitate folding and storing the first lifting arm 210.

[0055] Further, referring to Figures 1 to 4As shown, in some embodiments, the fender lifting frame device 10 further comprises a cable mechanism 400, which comprises a winch 410, a first pulley block 420 and a first cable 430. The winch 410 is connected to the mounting base 100, for example, the winch 410 can be selected from a hydraulic drive winch 410, an electric winch 410, etc., the winch 410 can control the release and winding speed of the first cable 430 to ensure the smooth lifting process of the fender 20. And the winch 410 is fixed on the mounting base 100 between the first lifting arm 210 and the second lifting arm 220, so as to cooperate with the first lifting arm 210 and the second lifting arm 220 respectively through the cable to lift the fender 20. The first pulley block 420 is connected to the side of the first lifting arm 210 away from the second lifting arm 220, for example, the first pulley block 420 can comprise three fixed pulleys, which are respectively installed at the connection between the support section 2111 of the first support arm 211 and the first connecting section 2112, the connection between the second connecting section 2121 of the first folding arm 212 and the folding section 2122, and the top end of the folding section 2122. And the center axes of the three fixed pulleys are parallel to each other, and the fixed pulleys are all installed on the side of the first lifting arm 210 away from the second lifting arm 220. The first cable 430 is connected to the winch 410 and in sliding cooperation with the first pulley block 420. For example, the first cable 430 can be selected from a steel wire rope, one end of the first cable 430 is fixedly connected to the winch 410, and the other end of the first cable 430 is connected to the lifting point of the fender 20 after passing through the fixed pulleys of the first pulley block 420 in sequence.

[0056] Therefore, by arranging the first pulley block 420 on the side of the first lifting arm 210 away from the second lifting arm 220, the first pulley block 420 does not occupy the space between the first lifting arm 210 and the second lifting arm 220, so that the space between the first lifting arm 210 and the second lifting arm 220 can be used to accommodate the fender 20, thereby minimizing the distance between the first lifting arm 210 and the second lifting arm 220 and reducing the space occupation of the fender lifting frame device 10, so as to alleviate the pressure on the deck layout of the floating facility. In particular, in some embodiments, referring to Figures 3 to 5 As shown, when the second rotation axis L2 of the rotating shaft 2131, the first rotation axis L1 and the center axes of the fixed pulleys included in the first pulley block 420 are parallel to each other, at this time, since the first folding arm 212 is rotated towards the opening side to realize folding, the first cable 430 cooperating with the first pulley block 420 will not be separated from the first pulley block 420 during the rotation of the first folding arm 212, so that the folding function can be realized by controlling the folding direction and the folding position, and the cooperation relationship between the first cable 430 and the first pulley block 420 can be avoided from being affected.

[0057] In the process of transferring the fender 20, the first hoist arm 210 and the first cable 430 not only need to bear the weight of the fender 20, but also need to bear the impact load generated when the fender 20 is hoisted and the whole floating facility moves. In order to further ensure the stability of the hoisting operation, the structure of the fender hanger device 10 can be further optimized.

[0058] Referring to FIG. 5, Figures 2 to 4 , Figure 6 In some embodiments, the fender hanger device 10 further comprises an energy absorption mechanism 500, which is arranged between the winch 410 and the first pulley block 420 and is elastically connected with the first cable 430. The elastic connection means that the energy absorption mechanism 500 can apply an elastic force to the first cable 430, so that the first cable 430 is in a tension state. When the pulling force of the first cable 430 increases or is impacted, the first cable 430 presses the energy absorption mechanism 500, at which time the energy absorption mechanism 500 can absorb the impact force to reduce the dynamic peak load on the first cable 430 and the first hoist arm 210, so that the external force acting on the first cable 430 is controlled within a safe range, effectively avoiding the first cable 430 from breaking and the structure from deforming due to instantaneous overload, and ensuring the hoisting stability and safety.

[0059] Further, referring to FIG. 6, Figure 6As shown, in some embodiments, the energy absorption mechanism 500 includes an energy absorber 510 and an energy absorption roller 520. The first cable 430 is in sliding fit with the energy absorption roller 520, and the energy absorber 510 is connected between the mounting base 100 and the energy absorption roller 520. The energy absorber 510 is configured to apply an elastic force to the first cable 430 through the energy absorption roller 520 and tension the first cable 430. For example, the energy absorber 510 can be a hydraulic shock absorber that relies on hydraulic damping to slow down and stop the object acting on it, thereby playing a buffering protection role. Of course, in other alternative embodiments, the energy absorber 510 can also be a damping spring or the like structure to meet the energy absorption requirement. One end of the energy absorber 510 is fixedly connected with the mounting base 100, and the other end of the energy absorber 510 is rotatably connected with the energy absorption roller 520, so that the energy absorption roller 520 can rotate relative to the energy absorber 510. The surface of the energy absorption roller 520 can be provided with an annular groove adapted to the first cable 430 to avoid the first cable 430 from sliding off. When the energy absorption mechanism 500 is installed on the mounting base 100, the central axis of the energy absorption roller 520 is perpendicular to the upper surface of the mounting base 100, i.e., the central axis of the energy absorption roller 520 is arranged in the vertical direction. Thus, after the first cable 430 is led out from the winch 410, it first passes through the annular groove of the energy absorption roller 520 and then extends to the first pulley block 420, and the energy absorber 510 applies an elastic force to the first cable 430 through the energy absorption roller 520 to keep the first cable 430 always tensioned. When the fender 20 is hoisted and the first cable 430 is subjected to increased tension due to wave impact, the first cable 430 presses the energy absorption roller 520, thereby compressing the energy absorber 510. At this time, the energy absorber 510 can absorb impact energy, improve energy absorption efficiency, and better adapt to dynamic load changes at sea.

[0060] Further, in some embodiments, at least one of the first boom 210 and the second boom 220 is provided with a guide mechanism 600 at the end away from the mounting base 100. Alternatively, both the first boom 210 and the second boom 220 are provided with the guide mechanism 600. Referring to Figure 3 、 Figure 7 and Figure 8 As shown, taking the first boom 210 as an example, the guide mechanism 600 is arranged at the end of the first boom 210 away from the mounting base 100, i.e., the top end of the first boom 210. The guide mechanism 600 can accurately guide the path of the first cable 430, control the in-out angle of the first cable 430, reduce the yaw and vibration of the first cable 430, and also avoid the first cable 430 from slipping off and biting the edge, thereby improving safety and prolonging the service life of the first cable 430 and the first pulley block 420.

[0061] Specifically, the guide mechanism 600 comprises a connecting frame 610, and a first guide roller 620, a second guide roller 630, a third guide roller 640 and a fourth guide roller 650 rotatably connected to the connecting frame 610. The first guide roller 620 and the second guide roller 630 are arranged in parallel, the third guide roller 640 and the fourth guide roller 650 are arranged in parallel, and the first guide roller 620 and the second guide roller 630 are perpendicular to the third guide roller 640 and the fourth guide roller 650. For example, the connecting frame 610 can be made of steel structure, and is fixed to the first boom 210 away from the mounting base 100 through bolts. The connecting frame 610 is provided with shaft holes for mounting the guide rollers. The first guide roller 620, the second guide roller 630, the third guide roller 640 and the fourth guide roller 650 are rotatably connected to the connecting frame 610 through corresponding shaft holes, and a rectangular limiting space is formed between the first guide roller 620, the second guide roller 630, the third guide roller 640 and the fourth guide roller 650. The first cable 430 is arranged in the rectangular limiting space and is circumferentially limited by the first guide roller 620, the second guide roller 630, the third guide roller 640 and the fourth guide roller 650, so that the first cable 430 cannot deviate and vibrate, thereby ensuring that the fender 20 connected with the first cable 430 always moves along the preset path, reducing the shaking amplitude of the fender 20 during lifting or transferring, making the operation more stable, and effectively avoiding the contact between the fender 20 and the first boom 210 or the hull plate of the alongside ship.
