Description

Technical Field

[0001] This invention relates to the field of liquefied gas carrier technology, and more particularly to an anti-rolling combination support and a ship. Background Technology

[0002] Currently, LNG (Liquefied Natural Gas) and LPG (Liquefied Petroleum Gas), as high-calorific-value, clean, and pollution-free new energy sources, are gaining increasing social recognition and are being widely used in industrial production, becoming major energy choices worldwide. Consequently, liquefied gas carriers, designed to transport these new energy sources, have emerged to meet this huge market demand. (See attached image) Figure 1 and attached Figure 2 As shown, most liquefied gas carriers currently use independent liquid tanks 100 located in the cargo hold of the main hull 200 for transporting new energy. The independent liquid tanks 100 are generally connected to the main hull 200 through multiple supports arranged vertically, laterally, and longitudinally, such as the upper part 10' and the lower part 20' of the anti-roll support, rather than being directly fixed to the main hull 200. In this way, when the ship is sailing at sea, under the influence of sea conditions and the weight of the liquid cargo, the hull will experience yaw, pitch, and heave movements. Such anti-roll and anti-pitch devices can protect the independent liquid tanks 100 to prevent them from moving relative to the main hull 200. However, the current support structure is still ineffective in resisting forced deformation under emergency conditions. Finite element stress analysis shows that the stress in this type of support structure is high, exceeding the allowable stress by several times, failing to meet the corresponding specifications. Even changing the local plate thickness cannot improve this situation unless the overall plate thickness of the support structure is increased, and the connection between it and the independent liquid tank 100 is locally thickened to meet the standards. Calculations show that the thickest part needs to reach at least 80mm. However, the support structure is usually made of low-temperature steel, making this improvement not only difficult to construct on-site but also complex, time-consuming, and labor-intensive. Therefore, how to ensure that the stress level of the support structure decreases under emergency conditions, facilitates on-site construction, guarantees work quality, and saves costs and reduces construction efficiency is a problem that needs to be solved by those in this field. Summary of the Invention

[0031] The technical solutions of the embodiments are further illustrated below in conjunction with the drawings and through specific embodiments.

[0032] As Figures 3-8As shown, the embodiment provides a anti-rolling combined support seat, which comprises a load-bearing support, a compression wood assembly 30 and an anti-rolling support seat 40, both sides of the anti-rolling support seat 40 are provided with load-bearing supports, and the anti-rolling support seat 40 and the load-bearing support are both provided with the compression wood assembly 30, and the inside of the anti-rolling support seat 40 is connected with the stern arc transition, and the outside of the anti-rolling support seat 40 is connected with the bow arc transition.

[0033] In another aspect, the ship is provided with an anti-rolling combined support seat, an independent liquid tank 100 and a main hull 200, and the anti-rolling combined support seat is located between the independent liquid tank 100 and the main hull 200.

[0034] Specifically, in the embodiment, the load-bearing supports are arranged on both sides of the anti-rolling support seat 40, which can effectively improve the stable connection between the independent liquid tank 100 and the main hull 200, and the compression wood assembly 30 is arranged between the anti-rolling support seat 40 and the load-bearing support, which can effectively improve the mechanical strength of the anti-rolling combined support seat as a whole, and avoid the relative movement between the independent liquid tank 100 and the main hull 200 in the longitudinal direction. Further, the inside of the anti-rolling support seat 40 is connected with the stern arc transition, and the outside of the anti-rolling support seat 40 is connected with the bow arc transition, which can increase the size of the effective load transfer path, so that the stress level of the entire support seat structure naturally decreases under the premise of constant total load, thereby reducing the stress concentration problem in emergency working conditions, effectively avoiding the structural damage caused by strength and fatigue problems, improving the operation safety of the entire ship, and at the same time, the structure of the anti-rolling support seat 40 and the load-bearing support can also leave sufficient construction space and facilitate on-site construction, so that the thickness of the low-temperature steel plate used can be reduced to the process range controllable by the factory, thereby reducing the construction work amount, reducing the construction period, improving the construction efficiency, ensuring the quality, and saving the procurement cost. Correspondingly, the ship provided with the anti-rolling combined support seat can also achieve the above effects.

[0035] The specific structure of the anti-rolling combined support seat in the embodiment will be described below.

[0036] As shown in the drawings, Figure 3As shown, the anti-rolling combined support seat in the embodiment includes a load-bearing support, a compression wood assembly 30 and an anti-rolling support seat 40, and is additionally provided with a top plate 50 and a surrounding plate 60. Specifically, the load-bearing support includes a load-bearing support upper portion 10 and a load-bearing support lower portion 20. In the embodiment, the anti-rolling combined support seat is placed between an independent liquid tank 100 and a main hull 200 of a ship, so as to avoid the movement of the independent liquid tank 100 in the main hull 200 and the like, and reduce the damage of structural stress to the entire support seat. Optionally, the anti-rolling support seat 40 is provided with a load-bearing support on each side, so as to ensure balanced support. For example, the two load-bearing supports are symmetrically arranged relative to the anti-rolling support seat 40. Further, the anti-rolling support seat 40 and the load-bearing support are both provided with the compression wood assembly 30, and the load-bearing support upper portion 10 and the load-bearing support lower portion 20 are both provided with the compression wood assembly 30 inside. In the embodiment, the compression wood assembly 30 inside the load-bearing support upper portion 10 and the load-bearing support lower portion 20 is arranged in the horizontal direction, and the compression wood assembly 30 between the anti-rolling support seat 40 and the load-bearing support is arranged in the vertical direction. In this way, the structural stress can be reduced in the vertical direction and the horizontal direction during the subsequent operation of the ship, the longitudinal movement of the independent liquid tank 100 relative to the main hull 200 is limited, and the operation safety of the ship is ensured. Figure 1 Further, in the embodiment, the direction along A is the stern end direction, and the direction along B is the bow end direction. The anti-rolling support seat 40 is provided with a first arc portion connected to the stern end arc transition inside, and the top plate 50 is provided outside the anti-rolling support seat 40 and is provided with a second arc portion connected to the bow end arc transition. Under the action of the first arc portion and the second arc portion, the problem of stress concentration can be greatly reduced, and the stable installation of the anti-rolling support seat 40 on the ship is strengthened. For example, the surrounding plate 60 is additionally provided inside the anti-rolling support seat 40 in the embodiment, so as to improve the mechanical strength of the entire support seat.

[0037] In combination with Figures 3-5As shown, the upper load-bearing support 10 and the lower load-bearing support 20 are both provided with the knee plate 11, the support web 12 and the panel 13, and the compression wood assembly 30 is arranged between the two panels 13 and at the middle position, that is, the upper load-bearing support 10 is arranged above the compression wood assembly 30, and the lower load-bearing support 20 is arranged below the compression wood assembly 30. Further, the support web 12 is arranged perpendicularly to the panel 13, and the knee plate 11 is fixed to the panel 13 and is perpendicular to the support web 12 and the panel 13, so as to realize the stable installation of the load-bearing support between the independent liquid tank 100 and the main hull 200. For example, the upper and lower sides of the two support webs 12 are connected to the independent liquid tank 100 and the panel 13, the panel 13 and the main hull 200 respectively, and the plurality of knee plates 11 are arranged between the independent liquid tank 100 and the panel 13, the main hull 200 and the panel 13, so as to ensure that the load-bearing support is uniformly stressed, and to avoid the subsequent longitudinal and directional movement of the independent liquid tank 100 in the main hull 200. Alternatively, in the embodiment, the end of the top plate 50 away from the anti-rolling support 40 is connected to the panel 13 of the lower load-bearing support 20, so as to provide stable support for the top plate 50.

[0038] In combination Figure 3 and Figure 5 As shown, the compression wood assembly 30 in the embodiment includes the inlaid block 31 and the laminated wood 32, and the inlaid block 31 in the embodiment is arranged around the outer side of the laminated wood 32, and the gap between the laminated wood 32 and the inlaid block 31 is filled with the epoxy resin 33, so as to ensure that the structures on both sides of the compression wood assembly 30 can be stably connected. For example, Figure 4 As shown, for example, the inlaid block 31 of the compression wood assembly 30 arranged inside the load-bearing support is arranged perpendicularly to the panel 13, so as to be able to fix the laminated wood 32. Correspondingly, other materials can also be selected to replace the epoxy resin 33 for filling in other embodiments, which will not be described here.

[0039] For example, Figures 3-4 and Figures 6-8As shown, the anti-rolling support seat 40 in the embodiment is provided with partitions 41, a bottom plate 42, a back elbow plate 43, side plates 44 and support elbow plates 45. Specifically, a plurality of partitions 41 are arranged in the horizontal direction and the vertical direction inside and outside the anti-rolling support seat 40, so as to enhance the stability of the anti-rolling support seat 40 between the independent liquid tank 100 and the main hull 200, and further ensure that the independent liquid tank 100 will not move longitudinally in the main hull 200. For example, in the embodiment, one layer of partitions 41 is arranged in the horizontal direction inside the anti-rolling support seat 40, and two rows of partitions 41 are arranged in the vertical direction inside the anti-rolling support seat 40. Further, one layer of partitions 41 is also arranged in the horizontal direction outside the anti-rolling support seat 40, and two rows of partitions 41 are also arranged in the vertical direction outside the anti-rolling support seat 40, which are arranged with the same spacing as the partitions 41 arranged in the vertical direction inside the anti-rolling support seat 40.

[0040] Further, the bottom plate 42 is arranged below the partitions 41 arranged in the horizontal direction inside the anti-rolling support seat 40 and is arranged in alignment with the partitions 41 arranged in the horizontal direction outside the anti-rolling support seat 40, so as to ensure that the forces acting on the inside and outside of the anti-rolling support seat 40 are opposite. Specifically, a partition 41 is also arranged vertically between the partitions 41 arranged in the horizontal direction inside the anti-rolling support seat 40 and the bottom plate 42, which is arranged in a position corresponding to the two rows of partitions 41 above the partitions 41 arranged in the horizontal direction. Figure 6 As shown, the bottom plate 42 in the embodiment is provided with a first arcuate portion, and the first arcuate portion is connected to the aft end arcuate portion in transition. For example, in the embodiment, the first arcuate portion is arranged on the left bow side protruding portion of the bottom plate 42, and a row of partitions 41 is also arranged above the protruding portion, so as to enhance the mechanical strength and effectively reduce the stress concentration problem of the entire support seat under the action of the first arcuate portion. For example, the protruding portion of the bottom plate 42 is increased by 1000 mm and 450 mm in length and width respectively relative to the original size, and the radius of the first arcuate portion is set to 500 mm. Correspondingly, a partition 41 can be additionally arranged outside the anti-rolling support seat 40 in alignment with the protruding portion, so as to ensure that the structure of the anti-rolling support seat 40 at this position is in force balance. Similarly, the wood compression assembly 30 arranged at this position is correspondingly increased in size, so as to connect the protruding portion and ensure the stable installation of the bottom plate 42.

[0041] As shown, Figure 3As shown, the back elbow plate 43 is arranged on the outer top of the anti-rolling support base 40 in the embodiment, and the back elbow plate 43 is also provided with arc structures and right-angle structures. Specifically, the right-angle structures are connected to the independent liquid tank 100 and the anti-rolling support base 40 respectively, and the arc structures can also reduce stress, thereby further improving the stable connection between the anti-rolling support base 40 and the independent liquid tank 100 through the back elbow plate 43, and further avoiding the relative movement between the independent liquid tank 100 and the main hull 200 in the longitudinal direction and the like. As shown in Figure 4 , Figure 6 and Figure 7 As shown, the extension part of the bottom plate 42 is vertically provided with side plates 44 in the embodiment, and the side plates 44 are provided with two, and the two side plates 44 are located on the outer side of the anti-rolling support base 40 and are connected to the independent liquid tank 100 and the main hull 200 respectively. Specifically, the two side plates 44 are symmetrically arranged about the center of the wood-pressing assembly 30, and the side plates 44 are also provided with arc structures to reduce stress. Specifically, the upper and lower sides of the side plate 44 located inside the anti-rolling support base 40 are connected to the independent liquid tank 100 and the bottom plate 42 respectively, and the upper and lower sides of the side plate 44 located outside the anti-rolling support base 40 are connected to the top plate 50 and the main hull 200 respectively, so as to ensure the stable installation of the bottom plate 42 and the top plate 50.

[0042] As shown in Figure 4 , Figure 6 and Figure 8 As shown, the support elbow plate 45 is arranged inside the anti-rolling support base 40 in the embodiment, and the support elbow plate 45 is arranged in parallel with the side plate 44 and is arranged in a spaced manner with the vertically arranged partition plate 41. Specifically, the support elbow plate 45 and the side plate 44 are arranged in a vertical direction in the embodiment, that is, the partition plate 41, the support elbow plate 45 and the side plate 44 are arranged in parallel and in a spaced manner inside the anti-rolling support base 40. Specifically, the support elbow plate 45 is arranged between two rows of partition plates 41, and the length is greater than the length of the partition plate 41. Half of the length of the bottom plate 42 in the embodiment is greater than the length of the support elbow plate 45 and the length of the partition plate 41 arranged in a vertical direction. Specifically, two groups of support elbow plates 45 and partition plates 41 are symmetrically arranged on the two sides inside the anti-rolling support base 40, and are located above the bottom plate 42. Alternatively, the support elbow plates 45 are arranged inside and outside the anti-rolling support base 40, and the two support elbow plates 45 located on the two sides of the wood-pressing assembly 30 are symmetrically arranged relative to the center of the wood-pressing assembly 30, and the support elbow plate 45 is also provided with an arc structure to reduce stress. Specifically, the upper and lower sides of the support elbow plate 45 located inside the anti-rolling support base 40 are connected to the independent liquid tank 100 and the bottom plate 42 respectively, and the upper and lower sides of the support elbow plate 45 located outside the anti-rolling support base 40 are connected to the top plate 50 and the main hull 200 respectively, so as to further ensure the stable installation of the bottom plate 42 and the top plate 50 in combination with the side plate 44.

[0043] As shown inFigures 3-4 and Figures 7-8 As shown, in this embodiment, the top plate 50 is provided with a horizontal portion and an inclined portion. Specifically, the top plate 50 is located outside the anti-sway support 40, and its two sides are respectively connected to the anti-sway support 40 and the load-bearing support. Optionally, the horizontal portion of the top plate 50 is aligned with the partition 41 arranged horizontally inside the anti-sway support 40, and a wood pressing assembly 30 is provided between the horizontal portion and the anti-sway support 40. The inclined portion is connected to one side of the panel 13 of the lower part 20 of the load-bearing support. Further, the top plate 50 near the bow end is also provided with a protrusion on the left bow side, and a second arc portion is provided on the protrusion, which is transitionally connected to the bow arc. Correspondingly, a row of partitions 41 is also provided on the protrusion, the position of which corresponds to the position of the partitions 41 of the protruding part of the bottom plate 42, thereby enhancing the mechanical strength of the protrusion and avoiding stress concentration problems under the action of the second arc portion. For example, the top plate 50 near the stern does not have a protrusion. If needed during use, it can be provided as required, and will not be elaborated here. For example, the protrusion of the top plate 50 is increased by 1500mm in length and 450mm in width relative to the original dimensions, and the radius of the second arc portion is set to 500mm. Further, the side plate 44 disposed outside the anti-roll support 40 is located at the protrusion of the top plate 50, and the partition 41 outside the anti-roll support 40 is located below the horizontal portion.

[0044] Combination Figure 3 and Figure 4 As shown, enclosing plates 60 are added to the inner wall of the anti-pitch support 40, and the stability of the anti-pitch support 40 can be effectively improved by the four enclosing plates 60. Furthermore, enclosing plates 60 can also be added between the load-bearing support and the anti-pitch support 40. Specifically, enclosing plates 60 are added to the outside of the anti-pitch support 40, below the independent liquid tank 100 between the load-bearing support and the anti-pitch support 40, and above the main hull 200 to improve the overall structural stability.

[0045] In another aspect, the ship is provided with the anti-rolling combined support seat, the independent liquid tank 100 and the main hull 200, and the anti-rolling combined support seat is located between the independent liquid tank 100 and the main hull 200, so that compared with the conventional support form in the prior art, the bow, stern end bearing support and the left bow side local arrangement are effectively integrated in the embodiment, so that the effective connection between the main hull 200 and the independent liquid tank 100 can be effectively increased, the path size of the effective load transmission is ensured to be large, and the stress level of the whole structure is naturally reduced under the premise that the total load is unchanged. Specifically, the rigidity of the left side plate in the original support in the prior art is too large, and there is no larger rigidity structure on the left side, so that the rigidity mutation exists, and the stress concentration occurs obviously at the front upper corner of the left side plate. Therefore, the rigidity convex edge problem in the whole support seat is effectively alleviated by the added side plate 44 and the gradual transition form by using the arc structures, and the stress concentration problem can be correspondingly reduced, and the highest stress level of the whole structure is greatly reduced. Therefore, the structure stress can be effectively reduced by the anti-rolling combined support seat in the embodiment, the structure damage caused by the strength and fatigue problems can be avoided, the longitudinal movement of the independent liquid tank 100 relative to the main hull 200 is reduced, the operation safety of the ship is improved, and in addition, the construction space is left under the setting of the anti-rolling combined support seat in the embodiment, the thickness of the low-temperature steel plate is reduced to the controllable process range of the factory, the work amount of the full penetration welding of the rear plate is greatly reduced, the construction period is effectively reduced, the overall construction efficiency is improved, the quality is ensured, and the procurement cost of the thick low-temperature steel is saved.

[0046] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be exhausted.
