[0024] 13000m 3 The LNG fuel B-type tank has a larger volume and a larger weight than the conventional fuel tank. Moreover, during the strength test, water needs to be injected into the LNG fuel B-type tank, further increasing the weight of the LNG fuel B-type tank. The conventional supporting device is fixed on the test site, and it is difficult for the conventional supporting device to adjust the force balance of the LNG fuel B-type tank during the strength test of the LNG fuel B-type tank with a volume of 13000m 3 The conventional supporting device is difficult to adjust the force balance of the LNG fuel B-type tank, which is easy to cause the gravity of the LNG fuel B-type tank to concentrate on a certain position of the test site, and further cause damage to the test site. The present application aims at the above problems, and provides a B-type tank strength test supporting device for ships, which is used for supporting the B-type tank (i.e. the LNG fuel B-type tank described above), so that the B-type tank can adjust its balance during the strength test, avoiding stress concentration and causing damage to the test site.

[0025] Referring to Figure 1 and Figure 3The B-type cabin 1 includes a storage tank 11 and a plurality of sets of laminated wood groups. The storage tank 11 is a prismatic structure, i.e., the bottom surface of the storage tank 11 is a plane. The plurality of sets of laminated wood groups are arranged at intervals along the length direction of the storage tank 11. Each set of laminated wood groups includes a plurality of laminated woods 13 arranged at intervals along the width direction of the storage tank 11, so that the laminated woods 13 are uniformly distributed on the bottom surface of the storage tank 11 to form a plurality of support points of the B-type cabin 1. The top surface of the laminated wood 13 is fixedly connected to the bottom surface of the storage tank 11, and the bottom surface of the laminated wood 13 forms a support plane. In the embodiment shown in Figure 1 and Figure 3 , the laminated wood groups are provided in four groups, and each group of laminated wood groups includes six laminated woods 13. In other embodiments, the laminated wood groups can also be provided in two groups, three groups, five groups, or more, and the number of laminated woods 13 in each group of laminated wood groups is two, three, four, or other numbers.

[0026] In some embodiments, the B-type cabin 1 further includes a plurality of support seats 12 arranged between the storage tank 11 and the laminated wood 13. The support seat 12 is welded to the bottom surface of the storage tank 11, and the plurality of support seats 12 correspond one-to-one to the plurality of laminated woods 13. By providing the support seat 12, the stress intensity of the storage tank 11 at the support position is improved. The top surface of the laminated wood 13 is arranged in close contact with the bottom surface of the support seat 12, so that the contact area between the laminated wood 13 and the support seat 12 can be increased, and the gravity of the storage tank 11 is prevented from being concentrated on a certain position of the laminated wood 13. The laminated wood 13 is a special wood composite material, which has the characteristics of high strength, durability, and stability. Moreover, the thermal conductivity of the laminated wood 13 is low, and by providing the laminated wood 13, the cold energy of the storage tank 11 is prevented from being transmitted to the support device and the detection site, thereby affecting the stress intensity of the support device and the detection site.

[0027] In some embodiments, each set of laminated wood groups can also include only one laminated wood 13. The laminated wood 13 is in the form of a long strip, the length direction of the laminated wood 13 is consistent with the width direction of the storage tank 11, and the length of the laminated wood 13 is adapted to the width of the storage tank 11.

[0028] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the support device includes a plurality of sets of support assemblies 2 arranged at intervals in the horizontal direction. The plurality of sets of support assemblies 2 collectively support the B-type cabin 1, so that the B-type cabin 1 remains balanced.

[0029] The plurality of support assemblies 2 are arranged along the length direction of the storage tank 11, and the plurality of support assemblies 2 correspond to the plurality of laminated wood groups in position and are arranged below the laminated wood groups. The space between the adjacent two support assemblies 2 can be used for the carrying trolley carrying the B-type cabin 1 to pass through, so that the carrying trolley can carry the B-type cabin 1 to the position directly above the support beam 21. In other embodiments, the plurality of support assemblies 2 can also be arranged along the width direction of the B-type cabin 1, or arranged along the length direction and the width direction of the B-type cabin 1.

[0030] Each support assembly 2 includes a support beam 21 and a plurality of support structures 22. The support beam 21 is in a strip shape, the length direction of the support beam 21 is consistent with the width direction of the storage tank 11, and the support beam 21 is arranged below the laminated wood 13 of the corresponding same group. The plurality of support structures 22 of the same group of support assemblies 2 are arranged along the width direction of the storage tank 11 and correspond to the plurality of laminated woods 13 in position. The plurality of support structures 22 of the same group are arranged on the same support beam 21, so that the support assembly 2 supports the laminated wood 13 of the B-type cabin 1 through the support beam 21 and the support structure 22, thereby realizing the support of the support device to the storage tank 11 of the B-type cabin 1. Moreover, the plurality of support structures 22 of the same group are in contact with the detection site through the support beam 21, which increases the contact area between the support device and the detection site, and avoids the gravity of the B-type cabin 1 from being concentrated on a certain position, thereby avoiding the damage of the detection site due to stress concentration.

[0031] In the embodiments shown in Figure 2 and Figure 3 , the support device is provided with 4 groups of support assemblies 2, and each support assembly 2 is provided with 6 support structures 22. Each support structure 22 corresponds to each laminated wood 13 in position. In other embodiments, the support device can also be provided with 2 groups, 3 groups, 5 groups or more, and the number of support structures 22 of each support assembly 2 is 2, 3, 4 or other number.

[0032] Referring to Figure 4 , the support beam 21 is a reinforced structure with high stress strength. The support beam 21 includes a bottom plate 211, a top plate 212 and a connecting plate 213. The bottom plate 211 and the top plate 212 are arranged in the height direction and the top plate 212 is arranged above the bottom plate 211. The connecting plate 213 is arranged between the bottom plate 211 and the top plate 212, and the connecting plate 213 connects the bottom plate 211 and the top plate 212, so that the bottom plate 211, the top plate 212 and the connecting plate 213 form an integral whole.

[0033] In an embodiment, the support beam 21 further comprises a reinforcing rib 214, which is arranged on both sides of the support beam 21 in the width direction and fixedly connected with the connecting plate 213 close to the outer side of the support beam 21 in the width direction, so as to increase the stress strength of the connecting plate 213. The reinforcing rib 214 can be arranged in multiple pieces along the length direction of the connecting plate 213. Preferably, the plane where the reinforcing rib 214 is located is perpendicular to the length direction of the connecting plate 213.

[0034] The projection area of the bottom plate 211 in the vertical direction is greater than the projection area of the top plate 212 in the vertical direction, and the projection of the top plate 212 in the vertical direction is located on the bottom plate 211, so as to increase the contact area of the support beam 21 with the detection site. The connecting plate 213 is arranged in multiple pieces, and the multiple connecting plates 213 are arranged in the width direction of the top plate 212, so that the top plate 212 is supported by the multiple connecting plates 213, thereby increasing the stress strength of the support beam 21 and reducing the weight of the support beam 21.

[0035] In some embodiments, each group of support assemblies 2 can also comprise only one support structure 22, which is in the shape of a long strip, the length direction of the support structure 22 is consistent with the width direction of the storage tank 11, and the length of the support structure 22 is adapted to the width of the storage tank 11. The bottom surface of the laminated wood 13 of the same group abuts against the same support structure 22. In other embodiments, the support device can also not be provided with the support beam 21, and the hardwood structure 221 is directly placed on the detection site.

[0036] Referring to Figure 3 and Figure 4 Each support structure 22 comprises a hardwood structure 221 and a softwood structure 222. The hardwood structure 221 is detachably arranged on the top surface of the support beam 21, and the bottom surface of the hardwood structure 221 is attached to the top surface of the support beam 21. The softwood structure 222 is detachably arranged between the hardwood structure 221 and the support surface of the B-type cabin 1. The softwood structure 222 can be deformed under the pressure of the B-type cabin 1, so that the two side surfaces thereof in the height direction are attached to the hardwood structure 221 and the support surface of the B-type cabin 1, respectively.

[0037] The vertical projection area of the hard wood structure 221 and the soft wood structure 222 is greater than or equal to the area of the support plane, and the vertical projection of the hard wood structure 221 and the soft wood structure 222 is located within the top plate 212 of the support beam 21. When the soft wood structure 222 deforms under the pressure of the B-type cabin 1, so that the two sides of the soft wood structure 222 in the height direction are respectively attached to the hard wood structure 221 and the support plane of the B-type cabin 1, the stress area of the hard wood structure 221 can be increased, and the gravity of the B-type cabin 1 is uniformly distributed on each position of the stress area of the hard wood structure 221, thereby avoiding the problem that the gravity of the B-type cabin 1 is concentrated on a local position of the hard wood structure 221, causing damage to the test site or the support beam 21.

[0038] The hard wood structure 221 is used to support the B-type cabin 1, and the height of the hard wood structure 221 is adjusted to adjust the distance between the B-type cabin 1 and the ground of the detection site. The hard wood structure 221 can be detached from the detection site to facilitate the adjustment of the balance of the B-type cabin 1, and the stress point of the B-type cabin 1 can be flexibly adjusted to avoid the problem that the weight of the B-type cabin 1 is concentrated on a certain position of the detection site, causing damage to the detection site.

[0039] The hard wood structure 221 includes a plurality of hard woods 2211, which are walnut, yellow pineapple, camphor wood, montana, nanmu, water willow, holboellia, locust wood, color wood, jackfruit, rosewood, or eucalyptus. The hard wood 2211 is a wood strip structure, which has a flat surface, so that the plurality of hard woods 2211 can be laid together, and the hard wood 2211 can be attached to the top surface of the support beam 21, and the top surface of the hard wood structure 221 is located on the same plane to maintain the balance of the B-type cabin 1.

[0040] For example, referring to Figure 5 , the plurality of hard woods 2211 are arranged in multiple layers in the thickness direction. Each layer of the plurality of hard woods 2211 is distributed along the width direction thereof, and the length directions of the hard woods 2211 between adjacent two layers are perpendicular to each other, that is, the adjacent two layers are arranged in a "#" shape, so that the hard wood structure 221 arranged in multiple layers is more stable and safer. When adjusting the distance between the B-type cabin 1 and the ground of the detection site, the number of layers of the hard woods 2211 arranged in multiple layers and the hard woods 2211 with different thicknesses can be selected according to the height requirement.

[0041] For example, the plurality of hard woods 2211 are arranged in a single layer in the thickness direction along the width direction thereof, and the thickness direction of the hard wood 2211 is consistent with the height direction of the support structure 22. When adjusting the distance between the B-type cabin 1 and the ground of the detection site, the hard woods 2211 with different thicknesses can be selected according to the height requirement.

[0042] In a preferred embodiment, the cross section of the hardwood structure 221 is rectangular, and the side length of the hardwood structure 221 is 1000mm-2500mm, and the height of the hardwood structure 221 is 150mm-300mm, so that the length and width of the hardwood structure 221 are much greater than the height of the hardwood structure 221, so that the hardwood structure 221 will not be overturned. Preferably, the length of each piece of hardwood 2211 is 1000mm-2500mm, the width is 50mm-150mm, and the thickness is 20mm-50mm, i.e. the thickness of the hardwood 2211 is less than the length and width of the hardwood 2211, so that the multiple pieces of hardwood 2211 laid together are not easy to fall off.

[0043] The multiple pieces of hardwood 2211 can be placed as needed, and the hardwood 2211 does not need to be fixedly connected with the hardwood 2211, so that the height and flatness of the top surface of the hardwood structure 221 can be conveniently adjusted, and the flexibility of use is improved. Moreover, by adjusting the height and position of the hardwood structure 221, the support device can be used for strength testing of different models of B-type cabins 1.

[0044] Referring to Figure 3 and Figure 4 , the vertical projection area of the softwood structure 222 is less than or equal to the vertical projection area of the hardwood structure 221, and the vertical projection of the softwood structure 222 is located on the hardwood structure 221, so that the softwood structure 222 can be stably placed on the hardwood structure 221. The softwood structure 222 is located between the hardwood structure 221 and the laminated wood 13, and by adjusting the height of the softwood structure 222, the distance between the B-type cabin 1 and the ground of the detection site can also be adjusted to a small extent.

[0045] The softwood structure 222 includes multiple pieces of softwood, which is white pine or corkwood, and the hardness of the softwood is smaller than that of the hardwood 2211, and the softwood can be slightly deformed under the extrusion of the B-type cabin 1, so that the softwood is attached to the hardwood 2211 and the laminated wood 13. The softwood is in the form of a wooden strip, and the surface is flat, so that multiple pieces of softwood can be conveniently laid together, and the softwood can be attached to the top surface of the support beam 21, and the top surface of the softwood structure 222 is located on the same plane, so as to maintain the balance of the B-type cabin 1. The laying mode of the multiple pieces of softwood is the same as that of the multiple pieces of hardwood 2211.

[0046] For example, the multiple pieces of softwood are distributed along the width direction and arranged in a single layer in the height direction. When adjusting the distance between the B-type cabin 1 and the ground of the detection site, softwood of different thicknesses can be selected according to the height requirement.

[0047] For example, the plurality of softwood pieces are arranged in multiple layers in the thickness direction. Each layer of the plurality of softwood pieces is distributed along the width direction, and the length direction of the softwood pieces between adjacent two layers is perpendicular to each other, i.e. the adjacent two layers are arranged in a "#" shape, so that the softwood structure 222 arranged in multiple layers is stable. When adjusting the distance between the B-type cabin 1 and the ground of the detection site, the number of layers of the softwood arranged in multiple layers and the softwood pieces with different thicknesses can be selected according to the height requirement.

[0048] In a preferred embodiment, the cross section of the softwood structure 222 is rectangular, the vertical projection area of the softwood structure 222 is equal to the vertical projection area of the hardwood structure 221, and the side length of the softwood structure 222 is 1000mm-2500mm, and the height of the softwood structure 222 is 20mm-40mm, so that the length and the width of the softwood structure 222 are much greater than the height of the softwood structure 222, and the softwood structure 222 will not overturn.

[0049] The vertical projection area of the softwood structure 222 is greater than the vertical projection area of the laminated wood 13, so that the softwood structure 222 can completely support each position of the bottom surface of the laminated wood 13, and the support device can more stably support the B-type cabin 1. Preferably, the vertical projection area of the softwood structure 222 is equal to the vertical projection area of the hardwood structure 221, the side of the top surface of the hardwood structure 221 is located outside the support plane, and the distance between the side of the top surface of the hardwood structure 221 and the corresponding side of the support plane is 10-30mm.

[0050] Different storage tanks 11 require different heights from the ground during strength test, and the support device of the present application comprises the hardwood structure 221 and the softwood structure 222, and the hardwood structure 221 and the softwood structure 222 can be detached from the detection site, so that the height of the storage tank 11 from the ground can be flexibly adjusted to meet the requirements of different storage tanks 11 for the height from the ground; and when the hardwood structure 221 and the softwood structure 222 are damaged due to large force, they can be easily replaced and the cost is low.

[0051] In the preparation work before the strength test, the support beam 21 is placed on the test site according to the requirements, and a plurality of support beams 21 are arranged in the horizontal direction at intervals, and the hardwood structure 221 and the softwood structure 222 are placed in turn according to the height of the ground required by the B-type cabin 1 during the strength test. Then the B-type cabin 1 is carried to the upper side of the support beam 21 by the carrying trolley, and the laminated wood 13 of the B-type cabin 1 corresponds to the position of the softwood structure 222, and then the B-type cabin 1 is placed on the softwood structure 222. Among them, when the stress of the B-type cabin 1 is unbalanced, the height of the hardwood structure 221 and the height of the softwood structure 222 of each support structure 22 are adjusted to balance the stress of the B-type cabin 1. Then the strength test is carried out. After the test, the B-type cabin 1 is removed, the hardwood structure 221 and the softwood structure 222 are cleaned, and the support beam 21 is adjusted to the initial state for next use. Among them, the B-type cabin 1 can be placed on the softwood structure 222 by hoisting; or using a carrying trolley with lifting function, the carrying trolley supporting the tray of the B-type cabin 1 is controlled to descend, so that the B-type cabin 1 is placed on the softwood structure 222.

[0052] The ship B-type cabin 1 strength test support device of the present application comprises a plurality of groups of support assemblies 2 arranged in the horizontal direction at intervals, the support assembly 2 comprises a hardwood structure 221 and a softwood structure 222, the softwood structure 222 is arranged above the hardwood structure 221, when the B-type cabin 1 is placed on the support device, the support plane of the B-type cabin 1 is located on the top surface of the softwood structure 222 to support the B-type cabin 1, so that the B-type cabin 1 has a set height from the ground, thereby meeting the height requirement of the B-type cabin 1 from the ground during the strength test; the hardwood structure 221 and the softwood structure 222 are detachably arranged, so that the stress balance of the B-type cabin 1 can be flexibly adjusted, the vertical projection area of the hardwood structure 221 and the softwood structure 222 is greater than or equal to the area of the support plane, so as to increase the area of the support device supporting the B-type cabin 1, and the softwood structure 222 deforms under the pressure of the B-type cabin 1, so that the two sides of the softwood structure 222 in the height direction respectively abut with the hardwood structure 221 and the support plane of the B-type cabin 1, thereby increasing the stress area of the hardwood structure 221, so that the gravity of the B-type cabin 1 is uniformly distributed on each position of the stress surface of the hardwood structure 221, thereby avoiding the problem that the gravity of the B-type cabin 1 is concentrated on the local position of the hardwood structure 221 and causes damage to the test site. Moreover, in the strength test, the hardwood structure 221 directly bears the weight of the B-type cabin 1 and the liquid during the strength test, thereby avoiding the problem that the gravity of the B-type cabin 1 acts on the test site and causes damage to the test site; and when the hardwood structure 221 is damaged due to large stress, it is convenient to replace, and the cost is low.

[0053] While the present application has been described with reference to several exemplary embodiments, it is understood that the words that have been used are words of description and illustration, rather than words of limitation.
