Abstract
Description
Technical Field
[0001] The invention relates to the technical field of liquefied gas transport ships, and in particular to an anti-pitch roll combined support seat and a ship. Background Art
[0002] At present, LNG (Liquefied Natural Gas) and LPG (Liquefied Petroleum Gas) are increasingly recognized by society as new energy sources with high calorific value, clean and pollution-free, and have begun to be widely used in industrial production, becoming the main energy choice in the world. As a result, liquefied gas transport ships carrying such new energy sources have also emerged in response to the huge demand market. Figure 1 and attached Figure 2 As shown, currently most liquefied gas transport ships use independent liquid tanks 100 arranged in the cargo hold on the main hull 200 to transport new energy, and the independent liquid tanks 100 are generally connected to the main hull 200 through multiple supports arranged vertically, horizontally and longitudinally, such as the upper part 10' and the lower part 20' of the anti-pitch support seat, rather than being directly fixed to the main hull 200. In this way, when the ship is sailing on the sea, under the influence of sea conditions and the dead weight of liquid cargo, when the hull produces transverse, longitudinal and heave movements, such anti-roll and anti-pitch devices can protect the independent liquid tanks 100 to avoid relative movement relative to the main hull 200. However, the effectiveness of the current support structure for forced deformation under emergency conditions is still relatively poor. Through the corresponding finite element stress analysis, it can be seen that the stress of this type of support structure is relatively high, and it exceeds the allowable stress by several times, and cannot meet the corresponding specification requirements. Timely changes in local plate thickness cannot improve this situation, unless the overall plate thickness of the support structure is increased, and the connection structure with the independent liquid tank 100 is locally thickened to pass the specification standards. Calculations show that the thickest part needs to be at least 80mm, and the support structure is usually made of low-temperature steel. This improvement measure is not only difficult to construct on site, but also its process is complicated, time-consuming and labor-intensive. Therefore, how to ensure that the stress level of the support structure is reduced under emergency conditions, and facilitate on-site construction, while ensuring the quality of the work, saving costs and reducing construction efficiency is a problem that people in this field need to solve.

[0031] The technical solution of this embodiment is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0032] like Figure 3-Figure 8As shown, this embodiment provides an anti-pitch roll combined support seat, including a load-bearing support, a compression wood assembly 30 and an anti-pitch roll support seat 40, and the load-bearing supports are respectively arranged on both sides of the anti-pitch roll support seat 40, and the compression wood assembly 30 is arranged between the anti-pitch roll support seat 40 and the load-bearing support, and the interior of the anti-pitch roll support seat 40 is transitionally connected with the stern end circular arc, and the exterior of the anti-pitch roll support seat 40 is transitionally connected with the bow end circular arc.
[0033] On the other hand, the ship is provided with an anti-pitch rolling combined support seat, an independent liquid tank 100 and a main hull 200 , and the anti-pitch rolling combined support seat is located between the independent liquid tank 100 and the main hull 200 .
[0034] Specifically, in this embodiment, load-bearing supports are respectively arranged on both sides of the anti-pitch roll support seat 40, which can effectively improve the stable connection between the independent liquid tank 100 and the main hull 200, and a pressed wood assembly 30 is arranged between the anti-pitch roll support seat 40 and the load-bearing supports, which can effectively improve the overall mechanical strength of the anti-pitch roll combination support seat and avoid longitudinal and other relative movements between the independent liquid tank 100 and the main hull 200. Furthermore, the interior of the anti-pitch support seat 40 is transitionally connected to the stern arc, and the exterior of the anti-pitch support seat 40 is transitionally connected to the bow arc, which can increase the size of the effective load transfer path, so that under the premise of the total load remaining unchanged, the stress level of the entire support seat structure naturally decreases, thereby reducing the stress concentration problem under emergency conditions, effectively avoiding structural damage caused by strength and fatigue problems, and improving the operational safety of the entire ship. At the same time, due to the structural setting of the anti-pitch support seat 40 and the load-bearing support, sufficient construction space can be left, and on-site construction is convenient, 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 workload, shortening the construction period, improving construction efficiency, ensuring quality, and saving procurement costs. Correspondingly, a ship equipped with an anti-pitch combined support seat can also achieve the above effects.
[0035] The specific structure of the anti-pitch roll combined support seat in this embodiment is described below.
[0036] like Figure 3As shown, in this embodiment, the anti-pitch roll combination support seat includes a load-bearing support, a pressed wood assembly 30 and an anti-pitch roll support seat 40, and is additionally provided with a top plate 50 and a shroud 60. Specifically, the load-bearing support includes a load-bearing support upper portion 10 and a load-bearing support lower portion 20, and in this embodiment, the anti-pitch roll combination support seat is placed between the independent liquid tank 100 and the main hull 200 of the ship to avoid the longitudinal movement of the independent liquid tank 100 in the main hull 200, and can reduce the damage to the entire support seat caused by structural stress. Optionally, in this embodiment, load-bearing supports are respectively provided on both sides of the anti-pitch roll support seat 40 to ensure balanced support. Exemplarily, the two load-bearing supports are symmetrically arranged relative to the anti-pitch roll support seat 40. Furthermore, a compression wood assembly 30 is provided between the anti-pitch support seat 40 and the load-bearing support, and a compression wood assembly 30 is provided inside both the upper part 10 of the load-bearing support and the lower part 20 of the load-bearing support. In this embodiment, the compression wood assemblies 30 inside the upper part 10 of the load-bearing support and the lower part 20 of the load-bearing support are arranged in the horizontal direction, and the compression wood assemblies 30 between the anti-pitch support seat 40 and the load-bearing support are arranged in the vertical direction. In this way, during the subsequent operation of the ship, the structural stress can be reduced in both the vertical and horizontal directions, and the longitudinal and other directional movement of the independent liquid tank 100 relative to the main hull 200 can be limited, while ensuring the operational safety of the ship. Combined with Figure 1 As shown, further, in this embodiment, along the A direction is the stern end direction, along the B direction is the bow end direction, the anti-pitch support seat 40 is provided with a first arc portion transitionally connected to the stern end arc, the anti-pitch support seat 40 is provided with a top plate 50 outside, and the top plate 50 is provided with a second arc portion transitionally connected to the bow end arc, 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-pitch support seat 40 on the ship is strengthened. Exemplarily, in this embodiment, a coaming 60 is added inside the anti-pitch support seat 40 to improve the mechanical strength of the entire support seat.
[0037] Combination Figure 3-Figure 5As shown, in this embodiment, the upper part 10 of the load-bearing support and the lower part 20 of the load-bearing support are both provided with a bracket 11, a supporting web 12 and a panel 13, and the pressed wood assembly 30 is arranged between the two panels 13 and located in the middle, that is, the upper part 10 of the load-bearing support is arranged above the pressed wood assembly 30, and the lower part 20 of the load-bearing support is arranged below the pressed wood assembly 30. Further, the supporting web 12 is arranged perpendicular to the panel 13, and the bracket 11 is perpendicular to the supporting web 12 and the panel 13 at the same time and fixed on 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. Exemplarily, the upper and lower sides of the two supporting webs 12 are respectively connected to the independent tank 100 and the panel 13, and the panel 13 and the main hull 200, and a plurality of brackets 11 are arranged between the independent tank 100 and the panel 13, and between the main hull 200 and the panel 13, so as to ensure that the load-bearing support is evenly stressed and prevent the subsequent independent tank 100 from moving in longitudinal and equidirectional directions in the main hull 200. Optionally, in this embodiment, one end of the top plate 50 away from the anti-pitch support seat 40 is connected to the panel 13 of the lower part 20 of the load-bearing support, so as to provide stable support for the top plate 50.
[0038] Combination Figure 3 and Figure 5 As shown, the pressed wood assembly 30 in this embodiment includes an inlay block 31 and a laminated wood 32. In this embodiment, the inlay block 31 is arranged around the outside of the laminated wood 32, and the gap between the laminated wood 32 and the inlay block 31 is filled with epoxy resin 33 to ensure that the structures on both sides of the pressed wood assembly 30 can be stably connected. Figure 4 As shown, for example, the inlay block 31 of the pressed wood assembly 30 located inside the load-bearing support is arranged perpendicular to the panel 13, so as to fix the laminated wood 32. Accordingly, in other embodiments, other materials can be selected to replace the epoxy resin 33 for filling, which will not be repeated here.
[0039] like Figure 3-Figure 4 and Figure 6-Figure 8As shown, in this embodiment, the anti-pitch support seat 40 is provided with a partition 41, a bottom plate 42, a back bracket 43, a side plate 44 and a support bracket 45. Specifically, a plurality of partitions 41 are arranged at intervals inside and outside the anti-pitch support seat 40 in the horizontal direction and the vertical direction, so as to enhance the stability of the anti-pitch support seat 40 between the independent liquid tank 100 and the main hull 200, thereby ensuring that the independent liquid tank 100 will not move longitudinally in the main hull 200. Exemplarily, in this embodiment, a layer of partitions 41 is arranged in the horizontal direction inside the anti-pitch support seat 40, and two rows of partitions 41 are arranged in the vertical direction inside. Furthermore, a layer of partition 41 is also arranged on the outside of the anti-pitch support seat 40 along the horizontal direction, and the height of the partition 41 is lower than the height of the partition 41 arranged on the inside of the anti-pitch support seat 40 along the horizontal direction, and two rows of partitions 41 are also arranged on the outside along the vertical direction, and the spacing size and other parameters thereof are corresponding to the partitions 41 arranged on the inside of the anti-pitch support seat 40 along the vertical direction.
[0040] Furthermore, a bottom plate 42 is provided below the partition plate 41 provided horizontally inside the anti-pitch support seat 40, and is aligned with the partition plate 41 provided horizontally outside the anti-pitch support seat 40, so as to ensure that the inner and outer forces of the sides of the anti-pitch support seat 40 are opposite. Specifically, a partition plate 41 is also provided vertically between the partition plate 41 provided horizontally inside the anti-pitch support seat 40 and the bottom plate 42, and its position is provided corresponding to the two rows of partition plates 41 above the horizontal partition plates 41. Figure 6 As shown, in this embodiment, a first arc portion is provided on the bottom plate 42, and the first arc portion is transitionally connected with the arc at the stern end. By way of example, in this embodiment, a first arc portion is provided on the left bow side extension portion of the bottom plate 42, and a row of partitions 41 are correspondingly provided above the extension 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 arc portion. By way of example, the extension portion of the bottom plate 42 is increased by 1000mm and 450mm in length and width respectively relative to the original size, and the radius of the first arc portion is set to 500mm. Accordingly, a partition 41 can be added to the outside of the anti-pitch support seat 40 in alignment with the extension portion, so as to ensure the structural force balance of the anti-pitch support seat 40 here. Similarly, the pressed wood assembly 30 provided here is correspondingly increased in size, so as to connect the extension portion and ensure the stable installation of the bottom plate 42.
[0041] like Figure 3As shown, in this embodiment, a back bracket 43 is provided on the top of the outer side of the anti-pitch support seat 40, and an arc structure and a right-angle structure are also provided on the back bracket 43. Specifically, the right-angle structure is connected to the independent liquid tank 100 and the anti-pitch support seat 40 respectively, and the arc structure can also reduce stress, thereby further improving the stable connection between the anti-pitch support seat 40 and the independent liquid tank 100 through the back bracket 43, and further avoiding the longitudinal relative movement between the independent liquid tank 100 and the main hull 200. Figure 4 , Figure 6 and Figure 7 As shown, in this embodiment, the extended portion of the bottom plate 42 is vertically provided with a side plate 44, and two side plates 44 are provided. The two side plates 44 are located outside the anti-pitch support seat 40, and are respectively connected to the independent liquid tank 100 and the main hull 200 up and down. Specifically, the two side plates 44 are symmetrically arranged about the center of the pressed wood assembly 30 here, and an arc structure is also provided on the side plates 44 to reduce stress. Exemplarily, the upper and lower sides of the side plate 44 located inside the anti-pitch support seat 40 are respectively connected to the independent liquid tank 100 and the bottom plate 42, and the upper and lower sides of the side plate 44 located outside the anti-pitch support seat 40 are respectively connected to the top plate 50 and the main hull 200, so as to ensure the stable installation of the bottom plate 42 and the top plate 50.
[0042] Combination Figure 4 , Figure 6 and Figure 8 As shown, in this embodiment, a support toggle plate 45 is provided inside the anti-pitch support seat 40, and the support toggle plate 45 is provided in parallel with the side plate 44, and is spaced apart from the partition plate 41 provided in the vertical direction. Specifically, in this embodiment, the support toggle plate 45 and the side plate 44 are both provided in the vertical direction, that is, the internal partition plate 41, the support toggle plate 45 and the side plate 44 of the anti-pitch support seat 40 are parallel and spaced apart. Exemplarily, the support toggle plate 45 is provided between two rows of partition plates 41, and its length is greater than the length of the partition plate 41. In this embodiment, half of the length of the bottom plate 42 is greater than the length of the support toggle plate 45 and the length of the partition plate 41 provided in the vertical direction. Specifically, two groups of support toggle plates 45 and partition plates 41 are symmetrically provided on both sides inside the anti-pitch support seat 40, and are both located above the bottom plate 42. Optionally, support brackets 45 are provided inside and outside the anti-pitch support seat 40, and the two support brackets 45 located on both sides of the pressed wood assembly 30 are symmetrically arranged relative to the center of the pressed wood assembly 30, and an arc structure is also provided on the support brackets 45 to reduce stress. Exemplarily, the upper and lower sides of the support brackets 45 located inside the anti-pitch support seat 40 are respectively connected to the independent liquid tank 100 and the bottom plate 42, and the upper and lower sides of the support brackets 45 located outside the anti-pitch support seat 40 are respectively connected to the top plate 50 and the main hull 200, so as to further ensure the stable installation of the bottom plate 42 and the top plate 50 in combination with the side plates 44.
[0043] Combination Figure 3-Figure 4 and Figure 7-Figure 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-pitch support seat 40, and its two sides are respectively connected to the anti-pitch support seat 40 and the load-bearing support seat. Optionally, the horizontal portion of the top plate 50 is aligned with the partition 41 arranged in the horizontal direction inside the anti-pitch support seat 40, and a press wood assembly 30 is arranged between the horizontal portion and the anti-pitch support seat 40, and the inclined portion is connected to one side of the panel 13 of the lower part 20 of the load-bearing support seat. Further, the top plate 50 near the bow end is also provided with an extension portion along the left bow side, and a second arc portion is provided on the extension portion, and the second arc portion is transitionally connected with the bow end arc. Correspondingly, a row of partitions 41 are also provided on the extension portion, and its position corresponds to the position of the partition 41 of the extension portion of the bottom plate 42, so as to enhance the mechanical strength of the extension portion and avoid stress concentration problems under the action of the second arc portion. For example, the top plate 50 near the stern end is not provided with an extension part for the time being. If it is needed during use, it can be provided as needed, and no further description is given here. For example, the extension part of the top plate 50 is increased by 1500mm and 450mm in length and width respectively relative to the original size, and the radius of the second arc part is set to 500mm. Further, the side plate 44 provided outside the anti-pitch support seat 40 is located at the extension part of the top plate 50, and the partition plate 41 outside the anti-pitch support seat 40 is located below the horizontal part.
[0044] Combination Figure 3 and Figure 4 As shown, the inner wall of the anti-pitch support seat 40 is provided with a coaming 60, and the stability of the anti-pitch support seat 40 can be effectively improved by four coamings 60. Further, a coaming 60 can also be provided between the load-bearing support and the anti-pitch support seat 40. Specifically, coamings 60 are provided outside the anti-pitch support seat 40, below the independent liquid tank 100 between the load-bearing support and the anti-pitch support seat 40, and above the main hull 200 to improve the stability of the overall structure.
[0045] On the other hand, the ship is provided with the above-mentioned anti-pitch combined support seat, the independent liquid tank 100 and the main hull 200, and the anti-pitch combined support seat is located between the independent liquid tank 100 and the main hull 200. Therefore, compared with the conventional support form in the prior art, the bow and stern end load-bearing supports and the local arrangement of the left bow side are effectively integrated in this embodiment, so that the effective connection between the main hull 200 and the independent liquid tank 100 can be effectively increased, and the path size of the effective load transfer is increased, and under the premise of the total load remaining unchanged, the stress level of the entire structure is naturally reduced. Specifically, the stiffness of the left side plate of the original support in the prior art is too large, and there is no structure with greater stiffness on the left side, and there is a sudden change in stiffness, which makes the front upper corner of the left side plate obviously have stress concentration. Therefore, in this embodiment, by adding structures such as the side plate 44 and using the form of gradual transition of each arc structure, the stiffness convex edge problem in the entire support seat is effectively alleviated, and the stress concentration problem can be correspondingly reduced. In summary, the maximum stress level of the entire structure has been greatly reduced. Therefore, the anti-pitch roll combined support seat in this embodiment can effectively reduce structural stress, avoid structural damage caused by strength and fatigue problems, and thereby reduce the longitudinal movement of the independent liquid tank 100 relative to the main hull 200, thereby improving the operational safety of the ship. In addition, the setting of the anti-pitch roll combined support seat in this embodiment leaves enough construction space, which is convenient for reducing the thickness of the low-temperature steel plate to within the process range controllable by the factory, greatly reducing the construction workload of full penetration welding of the rear plate, thereby effectively reducing the construction period, improving the overall construction efficiency, ensuring quality while saving the procurement cost of thick low-temperature steel.
