Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a method for constructing a hyperboloid deck for ships and the hyperboloid deck itself. Background Technology

[0002] like Figure 1 and Figure 2 As shown, the hyperboloid deck 100 of the ship has transverse arch beams to facilitate deck drainage and longitudinal ridges to optimize the hull line and reduce wave impact during navigation. Currently, the hyperboloid deck 100 is generally assembled using a semi-automatic CO2 gas-protected backing welding process at the jig station: first, the single deck plate is linearly shaped, and then the shaped plate 10 is laid on the jig column 200, which has been adjusted to the ground level 300, ensuring that the shaped plate 10 is completely in contact with the jig support surface; after adjacent shaped plates 10 are assembled, they are butt-welded using CO2 semi-automatic backing welding to form the splice seam 16, realizing the assembly of the hyperboloid deck 100. The above-mentioned traditional process has the following technical drawbacks: the linear shape of each deck plate is processed mechanically or by fire, firstly, the forming process is labor-intensive, the early processing cycle of the plates is long, and it restricts the overall construction progress; secondly, the dimensional control requirements of the shaped plates 10 are high, and the processing errors of the plates are easy to accumulate step by step, eventually causing the overall dimensions and outline of the hyperboloid deck 100 to exceed the tolerance. Summary of the Invention

[0003] The purpose of this invention is to provide a method for constructing a hyperboloid deck for ships and a hyperboloid deck itself, thereby shortening the construction cycle while ensuring the overall forming accuracy of the hyperboloid deck.

[0004] To achieve this objective, the present invention adopts the following technical solution: A method for constructing a marine hyperboloid deck includes: S100. Design an unfolded view of the hyperboloid deck in its unfolded and flattened state. The unfolded view of the hyperboloid deck includes multiple flat plates. The flat plates extend longitudinally and are arranged laterally to form a flat panel. S200. On the unfolded drawing of the hyperboloid deck, dimensions are marked for multiple flat plates and flat plate panels to form a flat plate panel design drawing. S300. Based on the flat panel design drawing, prepare a plurality of corresponding flat panel materials; S400: Weld multiple of the said flat plates to form the flat plate panel; S500, The flat panel is molded.

[0005] In some embodiments, step S200 further includes: drawing theoretical panel alignment lines on the unfolded view of the hyperboloid deck; Step S300 further includes: during the board cutting stage, according to the theoretical splicing line, applying fluorescent splicing line to the surface of the flat board; Step S400 further includes: before performing submerged arc welding on the multiple flat plates, verifying the position of the flat plates by means of the fluorescent panel alignment line.

[0006] In some embodiments, when drawing the alignment lines for the theoretical mosaic, the process includes: On the unfolded view of the hyperboloid deck, draw a straight line in the transverse direction that runs through the flat panel; the straight line is the theoretical panel mating line. The long side of the flat plate intersects with the theoretical splicing line. The distance from the intersection point to the corresponding end of the flat plate is measured and recorded along the longitudinal direction.

[0007] In some embodiments, the mold for compression molding includes an upper mold and a lower mold. The lower mold is a hyperboloid jig, the surface of which is adapted to the curved shape of the hyperboloid deck. The upper mold is an auxiliary tooling. In step S500, the flat panel is moved onto the hyperboloid jig, and the press drives the auxiliary tooling downward and presses the flat panel, so that the flat panel is completely fitted with the surface of the hyperboloid jig to form the hyperboloid deck.

[0008] In some embodiments, step S200 further includes: drawing theoretical equidistant inspection lines on the unfolded view of the hyperboloid deck; Step S300 further includes: during the plate cutting stage, applying fluorescent equidistant inspection lines to the surface of the flat plate according to the theoretical equidistant inspection lines; Step S500 further includes: after the flat panel is moved to the hyperboloid frame, the fluorescent equidistant inspection line forms a projection line on the ground, and the position of the flat panel is verified by the projection line.

[0009] In some embodiments, when drawing the theoretical equidistant inspection line, the method includes: drawing a curve in the horizontal direction through the flat panel on the unfolded view of the hyperboloid deck, the curve being the theoretical equidistant inspection line, the curve being parallel to and spaced from the end contour line of the flat panel, and recording the distance between the two.

[0010] In some embodiments, in step S200, the length and width of the plurality of flat panels, as well as the length, width and diagonal length of the flat panel assembly, are marked.

[0011] In some embodiments, in step S400, the flat plate is welded by submerged arc welding.

[0012] In some embodiments, step S100 further includes: unfolding and flattening the three-dimensional view of the hyperboloid deck in the model diagram to obtain an unfolded view of the hyperboloid deck in the unfolded and flattened state.

[0013] A hyperboloid deck is manufactured using the construction method for marine hyperboloid decks as described in any of the above schemes.

[0014] The beneficial effects of this invention are: This invention provides a method for constructing a marine hyperboloid deck and the hyperboloid deck itself. The method involves directly welding multiple flat plates together on the ground or platform to form a flat panel, and then molding the entire flat panel assembly to form the hyperboloid deck. Compared to the prior art, which involves independently molding individual plates before welding the assembled panels, this method reduces the difficulty of assembly by welding flat plates instead of individual plate forming, avoiding the need for single-piece forming, reducing pre-welding processing steps, lowering construction difficulty and complexity, and improving the dimensional accuracy of individual plates before welding. This reduces the accumulation of dimensional errors in individual plates before welding, ensuring the overall dimensional and contour accuracy of the flat plates, guaranteeing the overall forming accuracy of the hyperboloid deck, and improving the quality and efficiency of the flat panel assembly. Furthermore, molding the entire flat panel assembly replaces the independent processing of individual plates, reducing the workload of the forming process, thereby lowering construction costs, shortening the construction cycle, and ensuring construction progress. By optimizing the material preparation method and changing the welding method of the hyperboloid deck assembly, the construction difficulty is effectively reduced, and the construction quality and efficiency are improved.

[0017] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] like Figure 1 As shown, the ship's hyperboloid deck 100 has transverse beam arches to facilitate deck drainage and longitudinal ridges to optimize the hull lines and reduce wave impact during navigation. The X-axis is transverse, the Y-axis is longitudinal, and the Z-axis is vertical.

[0021] like Figures 3-9 As shown, this embodiment provides a method for constructing a marine hyperboloid deck, including: S100, design an unfolded view 500 of the hyperboloid deck in its unfolded and flattened state. The unfolded view 500 of the hyperboloid deck includes multiple flat plates that extend longitudinally and are arranged laterally to form a flat panel 20. Optionally, in the model drawing, the three-dimensional view 400 of the hyperboloid deck is unfolded and flattened to obtain the unfolded view 500 of the hyperboloid deck in its unfolded and flattened state. For example, combined with... Figure 1 and Figure 3 In the model diagram, the hyperboloid deck 100 includes five shaped plates 10, which are arranged horizontally as follows: first shaped plate 11, second shaped plate 12, third shaped plate 13, fourth shaped plate 14, and fifth shaped plate 15. After being unfolded and flattened, the hyperboloid deck 100 is unfolded into a flat panel 20, which includes five flat plates, arranged horizontally as follows: first flat plate 21, second flat plate 22, third flat plate 23, fourth flat plate 24, and fifth flat plate 25. The first flat plate 21 corresponds to the first shaped plate 11, the second flat plate 22 corresponds to the second shaped plate 12, the third flat plate 23 corresponds to the third shaped plate 13, the fourth flat plate 24 corresponds to the fourth shaped plate 14, and the fifth flat plate 25 corresponds to the fifth shaped plate 15.

[0022] S200. On the unfolded drawing 500 of the hyperboloid deck, dimensions are marked for multiple flat panels and flat panel splices 20 to form a flat panel splice design drawing. Specifically, on the unfolded drawing 500 of the hyperboloid deck, the length (not shown in the figure) and width (not shown in the figure) of the flat panels, as well as the length (not shown in the figure), width (not shown in the figure), and diagonal length of the flat panel splice 20 are marked, with diagonal lengths a and b respectively. By marking multiple flat panels separately, the cutting of flat panels is facilitated, and a reference is provided for subsequent quality inspection, thereby improving the level of standardized construction.

[0023] S300. Based on the flat panel design drawing, prepare a number of corresponding flat panels, namely, prepare a first flat panel 21, a second flat panel 22, a third flat panel 23, a fourth flat panel 24 and a fifth flat panel 25 with the corresponding shapes on the flat panel design drawing.

[0024] S400. Weld multiple flat plates to form a flat plate panel 20; for example, the flat plates are welded by submerged arc welding, and a submerged arc welded panel seam 26 is formed between adjacent flat plates.

[0025] S500: The flat panel 20 is press-formed. Exemplarily, the mold for press-forming includes an upper mold and a lower mold, wherein the lower mold is a hyperboloid jig, the profile (convex) of which matches the curved shape of the hyperboloid deck 100; the upper mold is an auxiliary tooling, having a concave surface and arranged downwards. During operation, the press drives the auxiliary tooling downwards, pressing the flat panel 20 tightly, forcing the flat panel 20 to fit against the profile of the hyperboloid jig to complete the forming, thus forming the hyperboloid deck 100. Optionally, the hyperboloid jig includes multiple jig columns 200, which can directly adopt the jig structure in the prior art, where the existing jig support surface is the profile of the hyperboloid jig.

[0026] Multiple flat panels are directly welded together on the ground 300 or a platform (not a jig) to form a flat panel 20, which is then molded as a whole to form a hyperboloid deck 100. Compared to the prior art, which involves independently molding individual panels before welding the panel shape, this method offers several advantages. First, welding the flat panels replaces welding the molded panels 10, reducing the difficulty of panel assembly, avoiding the need for individual flat panel molding, reducing pre-welding processing steps, lowering construction difficulty and complexity, and improving the dimensional accuracy of individual panels before welding. This reduces the accumulation of dimensional errors in individual panels before welding, ensuring the overall dimensional and contour accuracy of the flat panels, guaranteeing the overall molding accuracy of the hyperboloid deck 100, and improving the quality and efficiency of the flat panel 20. Second, molding the entire flat panel 20 replaces the independent processing of individual panels, reducing the workload of molding steps, thereby lowering construction costs, shortening the construction cycle, and ensuring construction progress.

[0027] The CO2 semi-automatic welding method relies heavily on manual operation, resulting in low welding efficiency. Furthermore, weld quality is significantly affected by welder skills, working environment, and fluctuations in process parameters, leading to a high rate of welding defects, unstable weld quality, and poor weld consistency, thus impacting panel assembly efficiency and quality control. By employing submerged arc welding (SAW) for flat plates, manual intervention is reduced, improving overall panel assembly efficiency. Since SAW panel deformation is less than that of CO2 semi-automatic backing welding, it is more conducive to controlling deck panel dimensional deviations and deck flatness, thereby improving panel assembly welding efficiency and weld quality consistency. This enables improved quality and efficiency in the 100-segment fabrication of hyperboloid decks.

[0028] By welding flat plates at 300 on the ground and molding the entire flat plate assembly 20 on the hyperbolic jig, the production cycle of the 100-segment hyperbolic deck is shortened and the utilization rate of the hyperbolic jig is improved.

[0029] By optimizing the material cutting method of the hyperboloid deck 100 and changing the welding method of the hyperboloid deck panels, the splicing method of the hyperboloid deck 100 panels is transformed from the on-tire CO2 semi-automatic backing welding splicing method to the platform submerged arc welding splicing method. Then, the hyperboloid deck 100 is formed by mounting the panels on the tire, which effectively reduces the construction difficulty and improves the construction quality and efficiency.

[0030] Step S200 also includes: S210. On the unfolded diagram 500 of the hyperboloid deck, draw the theoretical splice alignment line P; specifically, drawing the theoretical splice alignment line P includes: S211. On the unfolded diagram 500 of the hyperboloid deck, draw a straight line in the horizontal direction that passes through the flat panel 20. The straight line is the theoretical panel mating line P. S212. The long side of the flat plate intersects with the theoretical splicing line P. Along the longitudinal direction, measure and record the distance from the intersection point to the end of the corresponding flat plate.

[0031] For example, such as Figure 6As shown, for ease of description, the X-axis represents the left-right direction, and the Y-axis represents the front-back direction. From left to right, the plates are: first plate 21, second plate 22, third plate 23, fourth plate 24, and fifth plate 25. Let the left long side of the first plate 21 be the first long side, the long side between the first plate 21 and the second plate 22 be the second long side, the long side between the second plate 22 and the third plate 23 be the third long side, the long side between the third plate 23 and the fourth plate 24 be the fourth long side, the long side between the fourth plate 24 and the fifth plate 25 be the fifth long side, and the right long side of the fifth plate 25 be the sixth long side. Therefore, from left to right, the plates are: first long side, second long side, third long side, fourth long side, fifth long side, and sixth long side.

[0032] On the sixth long side, starting at a distance L from the front end, draw a straight line (the theoretical splicing line P) that runs through the flat panel 20 in a left-right direction (i.e., horizontally). The theoretical splicing line P intersects the first, second, third, fourth, fifth, and sixth long sides to form intersection points, which are the first, second, third, fourth, fifth, and sixth intersection points from left to right. Measure the distances from each intersection point to the front end, which are L1, L2, L3, L4, L5, and L, respectively.

[0033] Step S300 further includes: during the board cutting stage, according to the theoretical splicing line P, a fluorescent splicing line M is applied to the surface of the flat board; for example, points L1 and L2 away from the ends are taken on the two long sides of the first flat board 21 and connected, and fluorescent paint is applied to this connection line to form the fluorescent splicing line M.

[0034] Step S400 also includes: before submerged arc welding of multiple flat plates, verifying the position of the flat plates by using a fluorescent panel to check the bonding line M.

[0035] The theoretical splicing alignment line P provides a reference for applying fluorescent splicing alignment line M to flat panels. Fluorescent splicing alignment line M provides a unified alignment benchmark when splicing multiple flat panels, effectively preventing misalignment, twisting, and height differences during splicing, and ensuring the accuracy of splicing position. As a unified alignment standard, fluorescent splicing alignment line M facilitates batch product inspection and quality traceability, ensuring product consistency.

[0036] Step S200 also includes: S220. On the unfolded diagram 500 of the hyperboloid deck, draw the theoretical equidistant inspection line Q. Specifically, drawing the theoretical equidistant inspection line Q includes: drawing a curve along the transverse direction through the flat panel 20 on the unfolded diagram 500 of the hyperboloid deck. The curve is the theoretical equidistant inspection line Q. The curve is parallel to and spaced from the end contour lines of the flat panel 20, and the distance between the two is recorded. Specifically, points are taken sequentially on the first long side, the second long side, the third long side, the fourth long side, the fifth long side, and the sixth long side, respectively, as point 1, point 2, point 3, point 4, point 5, and point 6. The distances between point 1, point 2, point 3, point 4, point 5, and point 6 and the corresponding end are all W. Connect point 1, point 2, point 3, point 4, point 5, and point 6 to form a smooth curve, which is the theoretical equidistant inspection line Q.

[0037] Step S300 further includes: during the material cutting stage, according to the theoretical equidistant inspection line Q, fluorescent equidistant inspection lines N are applied to the surface of the flat plate; for example, points W away from the end are taken on the two long sides of the first flat plate 21 and connected, and fluorescent paint is applied to these connecting lines to form fluorescent equidistant inspection lines N.

[0038] Step S500 further includes: after moving the flat panel 20 to the hyperboloid frame, the fluorescent equidistant inspection line N forms a projection line on the ground 300, and the position of the flat panel 20 is verified by the projection line. Using the projection line at a fixed distance W from the end as a unified measurement benchmark, the spacing, parallelism, and straightness can be intuitively determined without additional tools, reducing measurement errors and improving the efficiency of dimensional verification.

[0039] This embodiment also provides a hyperboloid deck, which is manufactured using the above-described marine hyperboloid deck construction method, thereby improving the construction quality and efficiency of the 100-segment hyperboloid deck.

[0040] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
