Description

Technical Field

[0001] This application relates to the field of shipbuilding. Specifically, it relates to an independent liquid tank vertical support and an installation method for the independent liquid tank vertical support. Background Art

[0002] A liquid tank is a special container on a ship for loading and storing liquid substances. Depending on the substances loaded, different types of liquid tanks can be used. For example, a cargo tank for loading cryogenic liquid cargo, and a fuel tank for storing liquefied gas fuel, etc. The structure of an independent liquid tank is independent and does not form part of the hull structure. When in use, it needs to be hoisted into the hull for placement. Since the total weight of the independent liquid tank after being filled with liquid is relatively large, special vertical supports need to be provided to effectively transfer the weight to the hull structure to ensure the stable placement of the independent liquid tank in the hull. During the navigation of the ship, external forces such as waves will affect it, causing irregular longitudinal movement. The vertical support can bear the dynamic load brought by these movements and reduce the impact on the hull structure. In addition, the liquid loaded in the liquid tank may be at an extremely low temperature (such as liquefied natural gas). By using heat-insulating materials in the vertical support, etc., the low temperature can be effectively blocked from being transferred from the liquid tank to the hull, preventing the hull temperature from dropping below the allowable value.

[0003] In the prior art, a vertical support usually consists of an upper support structure, a lower support structure, a pressure-bearing block, a pressure-bearing block backing plate structure, etc. In the existing vertical support, the pressure-bearing block is usually completely fixed to the upper support structure and the lower support structure respectively. Therefore, when the liquid tank displaces during the operation of the ship and the liquid tank itself deforms due to thermal expansion and contraction, there will be an obvious relative movement between the upper support structure and the lower support structure, which poses a risk of cracking of the pressure-bearing block and leads to damage to the vertical support. In addition, the pressure-bearing block is usually designed in the shape of a hexahedron with a flat side surface, which results in poor adhesion between the heat-insulating layer and the pressure-bearing block, difficult laying of the heat-insulating layer and easy separation from the pressure-bearing block, and there are many cavities and gaps inside the heat-insulating layer after laying, affecting the heat-insulating effect and making it difficult to block the low temperature from being transferred from the liquid tank to the hull. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide an independent liquid tank vertical support and an installation method for the independent liquid tank vertical support. The upper support part and the lower support part of the independent liquid tank vertical support can move relative to each other, thus avoiding deformation and cracking of the pressure-bearing block. At the same time, by providing a protruding part on the pressure-bearing block, the pressure-bearing capacity of the pressure-bearing block is enhanced and the heat-insulating performance of the heat-insulating layer is better guaranteed, reducing the occurrence of frosting, icing and cold spot problems.

[0005] In a first aspect, the present application provides a vertical support for an independent liquid tank, comprising an upper support part, a lower support part, a bearing plate and a pressure-bearing block. Among them, the upper support part includes an upper support top plate and upper support rib plates, and the upper surface of the upper support top plate is fixedly connected to the bottom surface of the independent liquid tank. The lower support part includes a lower support top plate and lower support rib plates, and the lower ends of the lower support rib plates are fixedly connected to the inner bottom of the ship's hull. The bearing plate is arranged above the lower support top plate, and a buffer layer is fixedly arranged between the bearing plate and the lower support top plate for connecting the bearing plate and the lower support top plate. The pressure-bearing block is arranged between the upper support part and the bearing plate. A convex part is arranged around the outside of the pressure-bearing block.

[0006] In an implementable solution, a splicing slot matching the shape of the upper support rib plate is arranged on the upper surface of the pressure-bearing block. During use, the upper support rib plate is inserted into the splicing slot.

[0007] In an implementable solution, the upper support rib plate is one of a fishbone shape, a zigzag shape and an X shape.

[0008] In an implementable solution, the bearing plate includes a backing plate and an annular shroud fixedly arranged on the lower surface of the backing plate. The height of the shroud is greater than the sum of the thicknesses of the lower support top plate and the buffer layer.

[0009] In an implementable solution, the shroud surrounds the outside of the lower support top plate, and there is an overflow gap between the inner side of the shroud and the side surface of the lower support top plate.

[0010] In an implementable solution, the shroud is horizontally projected inside the backing plate on the backing plate, and positioning holes are arranged on the part of the lower surface of the backing plate located outside the shroud.

[0011] In an implementable solution, an injection hole is penetratively arranged on the upper surface of the lower support top plate for injecting liquid buffer layer material.

[0012] In an implementable solution, the cross-sectional shape of the convex part of the pressure-bearing block is one of a square shape, a triangular shape and a trapezoidal shape.

[0013] In an implementable solution, the buffer layer is made of epoxy resin material.

[0014] In a second aspect, the present application further provides an installation method for a vertical support of an independent liquid tank, which is used for installing the vertical support of the independent liquid tank, and includes the following steps:

[0015] S1. Fix the upper support top plate of the upper support part to the bottom surface of the independent liquid tank, and then insert the upper support rib plate into the inside of the pressure-bearing block to realize the connection between the upper support part and the pressure-bearing block;

[0016] S2. Fix the lower support rib plates of the lower support part to the inner bottom of the ship's hull, and then place the bearing plate on the lower support top plate;

[0017] S3. Hoist the independent liquid tank as a whole, and set a support device between the bottom plate of the independent liquid tank and the inner bottom of the ship to support the support points of the bottom plate of the independent liquid tank, so that the pressure-bearing block and the pressure-bearing plate do not come into contact;

[0018] S4. Jack up the pressure-bearing plate to make the pressure-bearing plate contact the pressure-bearing block, and at the same time measure the pressure between the pressure-bearing plate and the pressure-bearing block. Stop jacking up when the pressure reaches the preset standard;

[0019] S5. After stopping jacking up the pressure-bearing plate, inject liquid buffer layer material between the upper support plate and the pressure-bearing plate through the injection hole, and then wait for the buffer layer material to solidify to form a buffer layer;

[0020] S6. Remove the support device and the jacking device to complete the installation process of the vertical support of the independent liquid tank.

[0021] In an implementable solution, before step S3, lay an insulating layer around the upper support part, and do not lay an insulating layer at the support points of the bottom plate of the independent liquid tank during the process to facilitate the placement of the support device; after step S6 ends, lay an insulating layer at the support points of the bottom plate of the independent liquid tank.

[0022] In an implementable solution, in step S4, use a jacking device to jack up the pressure-bearing plate; the jacking device includes a cross bar, a vertical bar and a driver, and a positioning pin matching the positioning hole of the pressure-bearing plate is arranged on the upper surface of the cross bar.

[0023] In an implementable solution, a pressure sensor is arranged on the upper surface of the cross bar of the jacking device, and in step S4, the pressure between the pressure-bearing plate and the pressure-bearing block is measured through the pressure sensor.

[0024] Compared with the prior art, the beneficial effects of the present application at least include:

[0025] The present application provides a vertical support for an independent liquid tank, and there is no fixed structure between the pressure-bearing block and the pressure-bearing plate. Therefore, when the independent liquid tank has a movement tendency due to the change of the ship speed or the independent liquid tank deforms due to thermal expansion and contraction, the upper support part and the lower support part can move relatively, that is, the lower surface of the pressure-bearing block and the upper surface of the pressure-bearing plate can slide, so as to avoid deformation and cracking of the pressure-bearing block to the greatest extent, and at the same time, it does not affect the support effect on the independent liquid tank in the vertical direction.

[0026] The vertical support of the independent liquid tank of the present application can share the stress generated by the low-temperature deformation of the liquid tank and the shaking of the ship during operation by setting a protruding part on the pressure-bearing block, reduce the cracking risk of the pressure-bearing block, and thus enhance the pressure-bearing capacity of the pressure-bearing block. In addition, in actual production and use, an insulating layer is usually provided at the bottom of the independent liquid tank of the ship to prevent the bottom of the hull from being affected by the low temperature of the independent liquid tank. Setting a protruding part on the pressure-bearing block also helps to enhance the combination of the insulating layer and the pressure-bearing block, better ensure the insulating performance of the insulating layer, and reduce the occurrence of frosting, icing and cold spot problems.

[0027] In addition, the vertical support of the independent liquid tank of the present application is also provided with a buffer layer between the bearing plate and the lower support top plate, which helps the bearing plate and the lower support top plate to contact more fully, makes the force on the lower support part uniform, and at the same time can improve the heat insulation effect and better avoid the low temperature of the independent liquid tank from being transmitted to the bottom of the hull.

[0044] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application claimed, but merely represents the selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0046] Such as Figures 1-2As shown in the figure, the present application provides a vertical support for an independent liquid tank, which includes an upper support part 1, a lower support part 2, a bearing plate 3 and a bearing block 4. Among them, the upper support part 1 includes an upper support top plate 101 and upper support rib plates 102, and the upper surface of the upper support top plate 101 is fixedly connected to the bottom surface of the independent liquid tank. In actual production, the upper support top plate 101 can be welded to the bottom surface 10 of the independent liquid tank, and the lower support rib plates 202 can be welded to the inner bottom 11 of the ship. The lower support part 2 includes a lower support top plate 201 and lower support rib plates 202, and the lower ends of the lower support rib plates 202 are fixedly connected to the inner bottom of the ship. The bearing plate 3 is arranged above the lower support top plate 201, and a buffer layer 303 is fixedly arranged between the bearing plate 3 and the lower support top plate 201 for connecting the bearing plate 3 and the lower support top plate 201. The bearing block 4 is arranged between the upper support part 1 and the bearing plate 3. A protruding part 401 is arranged around the outside of the bearing block 4.

[0047] As Figure 4 shown, a fitting slot 402 matching the shape of the upper support rib plate 102 is arranged on the upper surface of the bearing block 4. During use, the upper support rib plate 102 is inserted into the fitting slot 402. This plug-in design enables the upper support rib plate 102 to be quickly installed on the bearing block 4 without complex welding or bolt connection, greatly improving the installation efficiency, and can achieve a tight fit between the fitting slot 402 and the upper support rib plate 102, so that the upper support part 1 and the bearing block 4 form an integral body. The design of the fitting slot 402 can evenly distribute the stress on the contact surface between the upper support rib plate 102 and the bearing block 4, avoiding excessive local stress, thereby prolonging the service life of the structure. In addition, this plug-in connection method can also effectively resist shear force. Especially when the ship is affected by external forces such as waves, this connection method can better transmit and disperse the shear stress, preventing damage to the vertical support of the independent liquid tank.

[0048] The shape of the upper support rib plate 102 can be set according to actual needs. Specifically, as Figures 6-8 shown, the upper support rib plate 102 can be one of fishbone shape, square shape and X shape, and the shape of the fitting slot 402 can be set accordingly. As Figure 6 shown, in the fishbone-shaped upper support rib plate 102, the main rib plate provides the main supporting force, and the branch rib plates can disperse the stress to a wider area, thereby reducing local stress concentration and the risk of structural damage. As Figure 7 shown, in the square-shaped upper support rib plate 102, since a closed support frame is formed, higher overall stability can be provided, reducing the overall structural failure caused by local deformation. At the same time, the stress can be evenly distributed in the closed-loop structure, avoiding the problem of excessive local stress. As Figure 8As shown, in the X-shaped upper support rib plate 102, two intersecting rib plates form an "X" shape. Compared with other complex structures, the X-shaped rib plate can simplify the overall structure and reduce the weight while ensuring the support performance. Generally, if the independent liquid tank needs to maintain high stability under complex dynamic loads and disperse stress, the fishbone-shaped upper support rib plate 102 is preferably used; if higher overall stability is required and local stress concentration is reduced at the same time, the square-shaped upper support rib plate 102 is preferably used; if lightweight design or structural simplification is needed, the X-shaped upper support rib plate 102 is preferably used.

[0049] On the upper surface of the lower support top plate 201, an injection hole 203 can be penetratively provided for injecting liquid buffer layer material. Preferably, the buffer layer 303 can be made of epoxy resin material. Usually, liquid epoxy resin material can be poured between the bearing plate 3 and the lower support top plate 101, and the buffer layer 303 can be formed after the liquid epoxy resin cures. The epoxy resin material has good strength and toughness, and excellent anti-fatigue performance, and can better withstand the dynamic loads generated by external forces such as waves during ship navigation of the liquid tank, and helps reduce the risk of cracks and damage caused by fatigue. In addition, epoxy resin has certain heat insulation performance, and by using it in combination with heat insulation materials, the heat transfer can be further reduced to prevent the hull temperature from dropping below the allowable value.

[0050] When in use, as Figure 3 shown, the independent liquid tank vertical support is usually arranged between the independent liquid tank and the inner bottom of the ship to provide a vertical support force for the independent liquid tank and avoid the adverse impact of the low temperature of the independent liquid tank on the hull. According to different shapes, the independent liquid tank can be divided into different types such as rhomboid tanks, square tanks, and special-shaped tanks (not shown in the figure). Figure 3 The independent liquid tank shown is a rhomboid tank. Usually, multiple independent liquid tank vertical supports are arranged between the independent liquid tank and the inner bottom of the ship. Due to various reasons such as the flatness of the bottom surface of the independent liquid tank and the flatness of the inner bottom of the ship, the contact between the bottom surface of the independent liquid tank and each independent liquid tank vertical support may be insufficient. Therefore, the buffer layers of each independent liquid tank vertical support can be set to different thicknesses as appropriate to eliminate the dimensional error in the vertical direction and make the gravity of the independent liquid tank evenly applied to the inner bottom of the ship.

[0051] In the independent liquid tank vertical support of the present application, since there is no fixed structure between the pressure-bearing block 4 and the bearing plate 3, when the independent liquid tank has a movement tendency due to the change of the ship speed or the independent liquid tank deforms due to thermal expansion and contraction, the upper support part 1 and the lower support part 2 can move relatively, that is, the lower surface of the pressure-bearing block 4 and the upper surface of the bearing plate 3 can slide, so as to maximize the avoidance of deformation and cracking of the pressure-bearing block 4 without affecting the support effect on the independent liquid tank in the vertical direction.

[0052] The vertical support of the independent liquid tank of the present application can share the stress generated by the low-temperature deformation of the liquid tank and the rocking of the ship during operation on the pressure-bearing block by providing the protruding portion 401 on the pressure-bearing block, reduce the cracking risk of the pressure-bearing block, and thus enhance the pressure-bearing capacity of the pressure-bearing block. As Figure 5 shown, the cross-sectional shape of the protruding portion 401 of the pressure-bearing block 4 can be one of a square, a triangle, and a trapezoid, and can be specifically set as needed, and no excessive restrictions are imposed here.

[0053] In addition, in actual production and use, an insulating layer is usually provided at the bottom of the independent liquid tank of the ship to prevent the bottom of the hull from being affected by the low temperature of the independent liquid tank. The provision of the protruding portion 401 on the pressure-bearing block 4 also helps to enhance the bonding between the insulating layer and the pressure-bearing block 4, better ensure the insulating performance of the insulating layer, and reduce the occurrence of frosting, icing, and cold spot problems. In addition, the vertical support of the independent liquid tank of the present application also has a buffer layer 303 provided between the bearing plate 3 and the lower support top plate 201, which helps the bearing plate 3 and the lower support top plate 201 to come into fuller contact, make the force on the lower support portion 2 uniform, and at the same time can improve the insulating effect and better prevent the low temperature of the independent liquid tank from being transmitted to the bottom of the hull.

[0054] In one embodiment, as Figure 1 and Figure 2 shown, the bearing plate 3 includes a backing plate 301 and an annular shroud 302 fixedly provided on the lower surface of the backing plate 301, and the height of the shroud 302 is greater than the sum of the thicknesses of the lower support top plate 201 and the buffer layer 303. Preferably, there is the following formula: the height of the shroud 302 = the thickness of the lower support top plate 201 + the thickness of the buffer layer 303 + 2 mm. As Figure 9 shown, the shroud 302 surrounds the outside of the lower support top plate 201, and there is an overflow gap 321 between the inner side of the shroud 302 and the side surface of the lower support top plate 201.

[0055] Preferably, the backing plate 301 can be made of a material with a relatively low surface friction coefficient and a certain strength, including but not limited to stainless steel, high-strength composite materials, etc. In addition, the width of the overflow gap 321 can be set to 6 - 10 mm. When injecting the liquid buffer layer material between the lower support top plate 201 and the backing plate 301, the excess material will flow out along the overflow gap 321, which on the one hand has a pressure relief effect, and on the other hand helps the operator to observe whether the buffer layer material has been injected in place. By appropriately increasing the height of the shroud 302, it helps to confine the liquid buffer layer material within the area surrounded by the shroud 302 and prevent it from overflowing and contaminating other positions.

[0056] In one embodiment, as Figure 9 and Figure 10 shown, the horizontal projection of the shroud 302 on the backing plate 301 is inside the backing plate 301. As Figure 10As shown, positioning holes 311 can be provided in the lower surface of the backing plate 301 at the part located outside the surrounding plate 302. Preferably, as Figure 14 shown, one positioning hole 311 can be provided at each of the four corners of the backing plate 301 to make the force on the backing plate 301 more uniform. The specific setting method is not limited here.

[0057] This application also provides an installation method for the vertical support of an independent liquid tank, which is used to install the vertical support of the independent liquid tank. As Figure 11 and Figure 12 shown, the installation method for the vertical support of the independent liquid tank includes the following steps:

[0058] S1. Fix the upper support top plate 101 of the upper support part 1 to the bottom surface 10 of the independent liquid tank, and then insert the upper support rib plate 102 into the pressure-bearing block 4 to realize the connection between the upper support part 1 and the pressure-bearing block 4.

[0059] S2. Fix the lower support rib plate 202 of the lower support part 2 to the inner bottom 11 of the ship's hull, and then place the bearing plate 3 on the lower support top plate 201. The bearing plate 3 is not fixedly connected to the lower support top plate 201.

[0060] S3. Hoist the independent liquid tank as a whole, and set a support 5 between the bottom plate 10 of the independent liquid tank and the inner bottom 11 of the ship's hull to support the support points of the bottom plate 10 of the independent liquid tank, so that the pressure-bearing block 4 and the bearing plate 3 do not come into contact.

[0061] S4. Jack up the bearing plate 3 to make the bearing plate 3 contact the pressure-bearing block 4, and at the same time measure the pressure between the bearing plate 3 and the pressure-bearing block 4. When the pressure reaches the preset standard, stop jacking up. Usually, this preset standard can be set as the pressure value between the bearing plate 3 and the pressure-bearing block 4 when the independent liquid tank is actually working. At this time, the bearing plate 3 is separated from the lower support rib plate 202, and a gap is formed between the two.

[0062] S5. After stopping jacking up the bearing plate 3, inject a liquid buffer layer material into the gap between the lower support top plate 201 and the bearing plate 3 through the injection hole 203, and then wait for the buffer layer material to solidify to form a buffer layer 303. It is preferred to use an epoxy resin material to make the buffer layer 303. During the injection process, when it is observed that the buffer layer material overflows from the overflow gap 321, stop injecting.

[0063] S6. Remove the support 5 and the jack 6 to complete the installation process of the vertical support of the independent liquid tank.

[0064] In one embodiment, as Figure 12As shown, before step S3, a heat insulation layer 7 is laid around the upper support portion 1, and the heat insulation layer 7 is not laid at the support points of the independent liquid tank bottom plate 10 to facilitate the placement of the support 5. After waiting for the end of step S6, the heat insulation layer 7 is supplemented and laid at the support points of the independent liquid tank bottom plate 10.

[0065] In one embodiment, as Figure 12 shown, in step S4, a jack 6 is used to lift the bearing plate 3. As Figure 13 shown, the jack 6 includes a cross bar 601, a vertical bar 602 and a driver 603. Among them, a positioning pin 611 that cooperates with the positioning hole 311 of the bearing plate 3 is arranged on the upper surface of the cross bar 601. Usually, each vertical bar 602 corresponds to a driver 603, and each cross bar 601 can correspond to multiple vertical bars and drivers 603, which can be specifically determined according to requirements. As Figure 14 shown, multiple cross bars 601 can be set to lift the bearing plate 3, and multiple positioning pins 611 are respectively inserted into the corresponding positioning holes 311 to ensure uniform force on the cushion plate 301 of the bearing plate 3.

[0066] In one embodiment, a pressure sensor (not shown in the figure) can be arranged on the upper surface of the cross bar 601. In step S4, the pressure between the bearing plate 3 and the pressure bearing block 4 is measured. The pressure sensor can be one of a strain gauge pressure sensor, a piezoelectric pressure sensor or a resistive pressure sensor, and specific limitations are not made here.

[0067] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
