Description

Technical Field

[0001] The present invention relates to the technical field of LNG ships, and more particularly, to an installation device for the main layer 3B type box of the N096 cargo hold of an LNG ship and a method for installing the 3B type box. Background Art

[0002] A liquefied natural gas ship (referred to as "LNG ship", "LNG carrier") refers to a "ship" specifically designed to transport liquefied natural gas. An LNG ship is a carrier for transporting liquefied natural gas at -163 °C. In the N096 membrane containment system, there are 10 cargo hold walls. Longitudinally, there are 8 surfaces, with a cross-section of an octagon, and transversely, there are 8 adjacent surfaces. There is also a cargo hold wall at each end of the cargo hold. The surfaces of the cargo hold walls are adjacent to each other, and the angle formed by the adjacent surfaces is called a dihedral angle. Among them, the dihedral angle adjacent to the head and tail is called the transverse dihedral angle, and the dihedral angle formed by the longitudinal cargo hold surfaces adjacent to each other is called the longitudinal dihedral angle.

[0003] The 3B type box is the main layer insulation box for the transverse dihedral angle of the main layer shielding layer. The insulation box corresponding to the main layer plane of the longitudinal cargo hold wall forms a transition to complete the integrity of the main layer insulation layer at the transverse dihedral angle. They are all installed above the secondary layer shielding layer. The corresponding secondary layer shielding layer includes secondary layer tongues, secondary layer plates, secondary layer end plates, and Invar pipes of the transverse ring. Due to the particularity of its location, affected by the structures of the secondary layer shielding layer, the 3B type box does not directly contact the secondary shielding layer but is supported by means of a wedge block structure. Since the gaps between the 3B type boxes at different positions and the secondary shielding layer are different, the wedge block also provides a function of height adjustment here.

[0004] Traditional installation methods often have problems such as uneven installation gaps and large adjustment difficulties, which affect the installation efficiency and installation quality. Summary of the Invention

[0038] In order to enable those skilled in the art in the technical field to which the present application belongs to understand the present application more clearly, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0039] In addition, the present application may repeat reference numerals and / or reference letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0040] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other.

[0041] The present invention will be further described in detail below through specific implementation examples and with reference to the accompanying drawings.

[0042] Embodiment:

[0043] During the actual installation of the 3B type box, there will be flatness problems due to the local non-ideal plane of the secondary shielding layer. In addition, the height adjustment range provided by the wedge is limited. When the height is insufficient, thin wood slices need to be used in cooperation with the wedge to complete height adjustment and support functions. However, during the actual installation process, the height adjustment using the veneer and the wedge block itself cannot eliminate the gap between the wedge or the thin wood slice under the wedge and the secondary shielding. This gap is often too large to meet the process and specification requirements.

[0044] Refer to Figures 1 to 6 , the technical solution adopted to achieve the purpose of this application is that in the first aspect of this application, an installation device for the main layer 3B type box of the N096 cargo hold of an LNG ship is disclosed, which includes a base 100, a first wedge block 200, a plurality of second wedge blocks 300, a resin material 400, and a thin film 500. The base 100 includes a bottom plate 110 and a baffle 120 installed on the bottom plate 110. The plane of the first wedge block 200 abuts against the bottom plate 110. The inclined surface of the second wedge block 300 cooperates with the inclined surface of the first wedge block 200 so that the plane of the second wedge block 300 is parallel to the inclined surface of the first wedge block 200, and the height of each second wedge block 300 increases in sequence. The resin material 400 is filled on the plane of the second wedge block 300. The thin film 500 covers the upper surface of the resin material 400. Select one second wedge block 300 to form an assembly with the first wedge block 200, and the plane of the second wedge block 300 is lower than the top surface of the baffle 120, and the upper surface of the resin material 400 is flush with or lower than the top surface of the baffle 120.

[0045] The installation device for the main layer 3B type box of the LNG ship N096 cargo hold disclosed in the present invention effectively eliminates the gap between the second wedge block 300 and the secondary shielding layer through the cooperation of two second wedge blocks 300 and the filling of the resin material 400, ensuring the installation accuracy and bearing support function of the 3B type box, and improving the installation efficiency and installation quality. At the same time, the use of the thin film 500 effectively prevents the leakage of the resin material 400, further ensuring the installation effect.

[0046] In one embodiment, the base 100 is rectangular, and this design provides a stable support surface, ensuring the stability and reliability during the installation process. The bottom plate 110 is the main load-bearing part, while the baffle 120 is used to limit and adjust the position of the first wedge block 200. The baffle 120 is in a C shape to reserve an opening on the base 100. This design reserves an opening on the base 100. This opening not only facilitates the installation and disassembly of the first wedge block 200 and the second wedge block 300, but also allows fine adjustment when necessary. The thick side of the first wedge block 200 faces the opening, and the short side of the second wedge block 300 faces the opening. The first wedge block 200 serves as the foundation of the entire device, providing a stable support surface for the subsequent second wedge blocks 300.

[0047] The technical solution adopted to achieve the purpose of this application is that in the second aspect of this application, the present invention also discloses a method for installing a 3B-type box based on the installation device of the 3B-type box on the main layer of the N096 cargo hold of an LNG ship, including the following steps:

[0048] Measure the distance between the bottom of the 3B-type box 600 and the secondary layer shielding layer to obtain the measured gap.

[0049] Select two second wedge blocks 300. The inclined surfaces of the two second wedge blocks 300 cooperate so that the planes of the two second wedge blocks 300 are parallel. Fill the resin material 400 on the plane of one of the second wedge blocks 300 to obtain a wedge block combination, and make the height of the wedge block combination larger than the measured gap to ensure sufficient adjustment space during installation.

[0050] Cover the resin material 400 with a thin film 500. Slide the second wedge block 300 without the filled resin material 400 so that the height of the wedge block combination is less than the measured gap, and then invert the wedge block combination so that the thin film 500 abuts against the secondary layer shielding layer. Once in place, gradually reduce the misalignment between the two second wedge blocks 300 (i.e., increase their relative height), which can be achieved by gently tapping or rotating the wedge block without the filled resin material 400.

[0051] Then increase the height of the wedge block combination by reducing the misalignment between the two second wedge blocks 300, squeeze the resin material 400, and fully compensate for the gap between the secondary layer shielding layer and the bottom plate 110 of the 3B-type box 600.

[0052] After the resin material 400 is completely hardened, the 3B-type box 600 can be fixed at a predetermined position using an appropriate fixing device (such as a pressing plate nut). At this time, the gap between the 3B-type box 600 and the secondary layer shielding layer has been completely compensated by the resin material 400, ensuring the accuracy and stability of the installation.

[0053] The installation method of the 3B-type box 600 on the main layer of the N096 cargo hold of the LNG ship disclosed by the present invention can install the 3B-type box 600 on the main layer of the N096 cargo hold of the LNG ship efficiently and accurately, providing a strong guarantee for the safe operation of the ship. Through the cooperation of the two second wedge blocks 300 and the filling of the resin material 400, the precise adjustment of the installation gap of the 3B-type box 600 is realized, improving the installation efficiency and installation quality. At the same time, the use of the thin film 500 effectively prevents the leakage of the resin material 400, further ensuring the installation effect.

[0054] In one embodiment, first, the plane of the first wedge block 200 is abutted against the base 100, then a second wedge block 300 is selected to cooperate with the first wedge block 200, and the plane of the second wedge block 300 is made lower than the top surface of the baffle 120. Resin material 400 is filled on the plane of the second wedge block 300. After that, another second wedge block 300 is selected to cooperate with the second wedge block 300 filled with the resin material 400 to form a wedge block combination, and the height of the wedge block combination is made 0.5 mm - 1 mm larger than the measurement gap.

[0055] After filling the resin material 400, another second wedge block 300 is selected, and its inclined surface is placed opposite to the inclined surface of the second wedge block 300 filled with the resin material 400. By adjusting the relative positions between the two second wedge blocks 300, a wedge block combination can be formed. At this time, it should be ensured that the overall height of the wedge block combination is 0.5 mm to 1 mm larger than the measurement gap. This additional height difference is for precisely controlling the gap between the 3B-type box 600 and the sub-layer shielding layer by adjusting the position of the second wedge block 300 during subsequent installation. Of course, in other embodiments, this gap can also be set to other thicknesses, as long as it is ensured that the resin material 400 can basically fill all the gaps.

[0056] In one embodiment, the distance between the plane of the second wedge block 300 and the top surface of the baffle 120 is greater than 0.5 mm. This can ensure that the resin material 400 has a certain thickness, and when filling the resin material 400, it is ensured that the resin material 400 does not exceed the range of the baffle 120, and it is possible to better control the shape, thickness, and surface flatness of the resin material 400.

[0057] In one embodiment, first, the plane of the first wedge block 200 is abutted against the base 100, then a second wedge block 300 is selected to cooperate with the first wedge block 200 so that the distance between the plane of the second wedge block 300 and the top surface of the baffle 120 is 0.5 mm - 1 mm larger than the measurement gap. A reference plane is formed through the top surface of the baffle 120, which makes it easier to control the overall thickness and surface flatness of the resin material 400.

[0058] In one embodiment, two second wedge blocks 300 with the same height are selected for cooperation. The inclined surface of one of the second wedge blocks 300 is placed opposite to the inclined surface of the first wedge block 200 and gently slid to ensure tight cooperation between them. Of course, selecting two second wedge blocks 300 with the same height for cooperation is only one implementation method in this embodiment. In other implementation methods, it is also possible to select second wedge blocks 300 with different heights for cooperation.

[0059] In one embodiment, the resin material 400 is a resin material commonly used in the enclosure system. After mixing, it has an installation time of 2 - 3 hours and is completely hardened after 24 hours. After mixing, it has an operable time of 2 - 3 hours, that is, during this period, the resin material 400 can maintain its fluidity and plasticity, facilitating filling and adjustment. It is completely hardened after 24 hours. The hardened resin material 400 has high strength and stability, and can provide reliable support for the type 3B box 600.

[0060] Before the resin material 400 starts to cure but has not completely hardened (usually within 1 - 2 hours after mixing), place the type 3B box 600 on the adjusted combination of wedge blocks. Gently adjust the position of the type 3B box 600 so that the gap between it and the sub - layer shielding layer is as close as possible to the predetermined value. At this time, attention should be paid to avoiding applying excessive pressure to the resin material 400 to prevent it from deforming or affecting the curing effect. After the resin material 400 is completely hardened, check and tighten the fixing device again to ensure that the type 3B box 600 is stably and firmly installed in the predetermined position. At the same time, check whether the film 500 is still firmly adhered to the second wedge block 300, and if necessary, it can be removed.

[0061] In one embodiment, both the length and width of the film 500 are larger than the size of the resin material 400. One side edge of the film 500 is attached to the thick side of the second wedge block 300 corresponding to the applied resin material 400 with double - sided tape.

[0062] In one embodiment, gently tap the second wedge block without the resin material 400 with a hammer to reduce the misalignment between the two second wedge blocks and increase the height, thereby squeezing the resin material 400 to eliminate the gap and flatness between the second wedge block 300 and the sub - layer shielding layer. Adjusting the misalignment height between the second wedge blocks 300 by moving the second wedge block 300 is only one implementation method in this embodiment. In other embodiments, operations such as rotating the second wedge block 300 can also be used.

[0063] In one embodiment, after the two second wedge blocks 300 are completely aligned, scrape off the extruded excess resin material 400 during the applicable period of the resin material 400, and fix the type 3B box 600 with a pressing plate nut after the resin material 400 is completely hardened. After the two second wedge blocks 300 are completely aligned, immediately use an appropriate tool (such as a scraper) to scrape off the extruded excess resin material 400. Note that the action should be gentle and rapid to avoid curing of the resin material 400, ensuring that the edge of the scraped resin material 400 is flat without overflow or residue.

[0064] A method for installing a 3B-type box disclosed by the present invention effectively solves the problems of excessive gap and insufficient bearing support during the installation of the 3B-type box 600 on the main layer of the N096 cargo hold of an LNG ship. By fabricating an auxiliary installation device and utilizing the filling and supporting functions of a resin material 400, the installation accuracy and stability of the 3B-type box 600 are ensured. Meanwhile, this method is easy to operate and highly efficient, and is applicable to the construction field of the liquid cargo tank containment system of an LNG ship.

[0065] In one embodiment, the installation method for the 3B-type box 600 on the main layer of the N096 cargo hold of an LNG ship can be operated according to the following steps:

[0066] a) Fabricate an auxiliary installation device for the first wedge block 200 of the 3B-type box 600. This device includes a resin-coated base 100, which consists of a rectangular bottom plate 110 and baffles 120 on three sides above the bottom plate 110. The length and width of the space enclosed by the bottom plate 110 and the baffles 120 are slightly larger than the dimensions of the first wedge block 200 and the second wedge block 300. Install a first wedge block 200 on the floor, with the plane of the first wedge block 200 abutting against the bottom plate 110.

[0067] b) Prepare second wedge blocks 300 with different thickness specifications, and different specifications of the second wedge blocks 300 have different heights. The remaining dimensions and the slope of the inclined surface of the second wedge block 300 are the same as those of the first wedge block 200. Combine the second wedge blocks 300 with different specifications with the resin material 400-coated base 100. Place the first wedge block 200 with its plane facing down and its thick edge facing the opening, and place the corresponding second wedge block 300 with its inclined surface facing the first wedge block 200 and its narrow edge facing the opening of the resin base 100 to form two parallel planes, one plane abutting against the secondary layer shielding layer and the other plane abutting against the bottom of the 3B-type box. The height of the combined upper and lower planes is adjusted by the second wedge blocks 300 with different thickness specifications.

[0068] c) The combination of the first wedge block 200 and the second wedge block 300 is lower than the height of the baffle 120. Apply the resin material 400 on the top plane of the second wedge block 300. After applying the resin material 400, the resin material 400 is at the same height as the three-sided baffle 120.

[0069] d) Re-combine the second wedge block 300 coated with the resin material 400 with other second wedge blocks 300. The height of the combination after adding the resin material 400 is 0.5 - 1 mm larger than the installation gap.

[0070] e) Cover a layer of film 500 on the second wedge block 300 coated with the resin material 400. During installation, the film 500 corresponding to the second wedge block 300 faces the secondary layer shielding layer for installation, and the resin material 400 faces the secondary layer shielding layer.

[0071] f) When combining the second wedge blocks 300 coated with the resin material 400 and covered with the film 500 during installation, a dislocation is formed between the two second wedge blocks 300, so that the total height is less than the clearance height for installation and placement. Then, by reducing the dislocation between the second wedge blocks 300, the height is increased to squeeze the resin material 400, fully compensating for the clearance between the combination of the second wedge blocks 300 between the secondary shielding layer and the bottom plate 110 of the 3B-type box 600.

[0072] g) After the flatness, layer difference, and clearance index inspections of the 3B-type box 600 are submitted and meet the specification requirements, and the resin material 400 is completely hardened, use a flat-tip nail to obliquely drive into the side plate of the 3B-type box 600 and the wedge for final physical fixation. Thus, the installation of the 3B-type box 600 is completed.
