[0002] my country has a long history of building floating bridges. The traditional floating bridge structure is to build beams on the pontoon and then lay the bridge deck. It is easy to build and dismantle and has high mobility. With the vigorous development of the national economy, steel structures have been widely used due to their unique advantages, and steel structure pontoons have come into being. The shapes of pontoons are varied. The more common one is the ship-shaped pontoon. The line type of its bow and stern varies greatly, and it is a hyperbolic shape. In order to enhance the aesthetic appearance of the pontoon, its line type changes need to be smooth, which poses a challenge to the processing and manufacturing of steel structures. In particular, the drawing expression of hyperbolic parts and their processing and forming are both major problems currently faced. If the processing accuracy is not high, it will affect the overall beauty of the pontoon at the least, and it will be impossible to assemble and form at the worst, affecting the safety performance of the entire pontoon. The detailed design and construction drawings of the ship-shaped pontoon are an important guarantee for controlling its processing accuracy. In the prior art, the drawing expression accuracy of the hyperbolic parts in the detailed design and construction drawings of the ship-shaped pontoon is low. Summary of the invention

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0050] An embodiment of the present invention provides a method for in-depth design of a ship-shaped pontoon, which utilizes a three-dimensional line mold of the ship-shaped pontoon to disassemble the outer plate according to the line changes of each part, so as to achieve the effect of improving the drawing expression accuracy of hyperbolic parts in the in-depth design construction drawing.

[0051] According to an embodiment of the present invention, an embodiment of a method for in-depth design of a ship-shaped pontoon is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0052] In this embodiment, a ship-shaped pontoon in-depth design method is provided, which can be used in the above-mentioned computer system. Figure 1 is a flow chart of a method for in-depth design of a ship-shaped pontoon according to an embodiment of the present invention. The ship-shaped pontoon comprises: an outer plate and a plurality of preset unit elements, such as Figure 1 As shown, the process includes the following steps:

[0053] Step S101, obtaining line and surface data in the ship-shaped pontoon design drawing, and creating a three-dimensional line mold of the outer contour according to the line and surface data.

[0054] Specifically, according to the line and surface line type diagram and the corresponding type value table provided by the ship-shaped pontoon design drawing, the overall line type is lofted to create an accurate three-dimensional line model of the outer contour of the ship-shaped pontoon, such as Figure 2The figure shows a schematic diagram of the three-dimensional line model of the outer contour of the ship-shaped pontoon. The line-surface line type diagram is a diagram in a two-dimensional plane. According to the line-surface line type diagram and the corresponding type value table, the data in the type value table is appropriately encrypted, that is, between the points contained in the type value table, points are appropriately added, and then the type values ​​corresponding to the added points are added to the prototype value table, so that the data in the type value table is more dense, ensuring a smooth and uniform transition of the overall line type of the ship-shaped pontoon.

[0055] Step S102 , extracting outer contour graphics of a plurality of preset unit components from the outer contour three-dimensional line mold, and drawing a construction drawing of each preset unit component according to the outer contour graphics of each preset unit component.

[0056] Specifically, the preset unit element is a unit element with a small linear change in the ship-shaped pontoon, but a large impact on the molding of the ship-shaped pontoon. For example, the deck, bulkhead plate, and rib unit are the main unit elements of the ship-shaped pontoon. In particular, the bulkhead plate and rib unit serve as the inner skeleton of the ship-shaped pontoon and also as the "inner tube" of the pontoon manufacturing. Their processing accuracy directly affects the control accuracy of the entire pontoon appearance line. The outer contour graphics of the deck, bulkhead plate, and each rib unit are accurately extracted from the outer contour line mold, such as Figure 3 , Figure 4 , Figure 5 As shown in the figure, it is a schematic diagram of the outer contour of a typical deck, bulkhead plate, and rib unit. The outer contour of each unit is used as the shape control reference of the corresponding unit to draw the construction drawings of the deck, bulkhead plate, and each rib unit. The number of the rib unit and the corresponding type value of each rib must be reflected in the deck construction drawing. In the subsequent production process, each rib unit is produced according to the number of the rib unit. After the production is completed, the rib units are assembled according to the number; the type value corresponding to each rib can reflect the linear change of the deck unit. The deck is not a plane, but has a slope change, which echoes the type value in the tire frame drawing. The construction drawings of each unit are used to guide the manufacture of the unit. Compared with the overall loose parts assembly method, it is easier to control the processing accuracy and quality by prefabricating the unit as a manufacturing unit. By controlling the size of each unit after assembly and welding, the accuracy of the "inner tube" of the ship-shaped pontoon is improved.

[0057] Step S103, determining the three-dimensional figure of the outer panel according to the outer contour three-dimensional line mold, and disassembling the three-dimensional figure of the outer panel into multiple scattered units according to a preset disassembly principle.

[0058] Specifically, the three-dimensional graphics of the outer plate are determined according to the three-dimensional line model of the outer contour, and the outer plate is disassembled into scattered units for easy processing and manufacturing according to the linear variation characteristics of the outer plate and the preset disassembly principle. The outer plate includes: bottom plate, side plate, bow panel and stern panel. Since the scattered units of the outer plate are formed by bending flat steel plates, in order to ensure the accuracy and efficiency of bending, the side plate and bottom plate with relatively gentle linear variation are disassembled into larger scattered units, and the bow panel and stern panel with larger linear variation are disassembled into smaller scattered units. Figure 6 As shown, it is a schematic diagram of the outer panel after disassembly, and the entire outer panel is disassembled into N1-N7, a plurality of scattered units, which is only used as an example, but not limited to this.

[0059] In some optional implementations, the preset disassembly principle includes: making the linear change of the disassembled scattered units within a preset change threshold.

[0060] Specifically, the three-dimensional graphics of the outer plate are disassembled into scattered units manually. The linear change refers to the size of the value in the direction perpendicular to the steel plate surface within a unit area, which corresponds to the size of the change in the z-direction value in the type value diagram. Before disassembly, the linear changes of various parts of the outer plate are different. For example, the linear changes of the side outer plate and the bottom plate are small, and the linear changes of the bow panel and the stern panel are large. According to the requirements of the bending process, when the steel plate is bent to form the scattered units of the outer plate, there will be a limit on the bending angle. There will be a preset change threshold for the linear change of the corresponding scattered unit. Within the preset change threshold, it can be bent and formed at one time. Otherwise, it cannot be bent and formed at one time, and the accuracy of the scattered unit cannot be guaranteed. Therefore, the side outer plate and the bottom plate with relatively mild linear changes can be disassembled into scattered units with larger areas, and the bow panel and the stern panel with larger linear changes can be disassembled into scattered units with smaller areas to ensure that the linear changes of each scattered unit obtained by disassembly are within the preset change threshold.

[0061] Step S104, taking the construction drawings of the preset unit components as a reference, determining the frame drawings of the scattered units, and determining the construction drawings of the scattered units according to the frame drawings of the scattered units.

[0062] Specifically, in the outer plate of the ship-shaped pontoon, the line shape changes of the bottom plate and the side outer plate are relatively gentle. The parts processing drawings of the scattered units can be drawn according to the conventional method to guide the construction of the scattered units. The conventional method is a mature existing technology and will not be repeated here. The line shape of the bow panel and the stern panel changes greatly, and they are hyperbolic parts. They are the key points of the line shape control of the entire ship-shaped pontoon. Conventional equipment cannot be bent and formed in one time. It is necessary to combine the characteristics of line shape changes, take the established rib position line in the construction drawing of each preset unit as the reference, and add the line shape control points of each scattered unit of the bow panel and the stern panel through fitting to form the tire frame drawing of each scattered unit. The tire frame drawing of each scattered unit is used as a processing template to determine the construction drawing of each scattered unit to control the processing and forming accuracy of each scattered unit.

[0063] Step S105, assembling the construction drawings of the scattered units to obtain the outer panel construction drawings.

[0064] Specifically, the construction drawings of the scattered units are directly assembled according to the original positions to obtain the outer plate construction drawings of the ship-shaped pontoon.

[0065] The ship-shaped pontoon in-depth design method provided in this embodiment is easy to control the processing accuracy and quality by prefabricating the preset unit element as the preparation unit, which is conducive to improving the accuracy of the "inner tube" of the ship-shaped pontoon manufacturing. By determining the tire frame drawing of each scattered unit, the control points of the outer plate hyperbolic parts are increased, making the processing drawing of the hyperbolic parts smoother and improving the drawing expression accuracy of the hyperbolic parts. The overall linear accuracy of the ship-shaped pontoon is effectively controlled, the defect of poor appearance molding of the ship-shaped pontoon is solved, and the processing cost and actual use risk are reduced.

[0066] In this embodiment, a ship-shaped pontoon in-depth design method is provided, which can be used in the above-mentioned computer system. Figure 7 : is a flow chart of a method for deepening design of a ship-shaped pontoon according to an embodiment of the present invention. Figure 7 As shown, the process includes the following steps:

[0067] Step S201, obtain the line and surface data in the ship-shaped pontoon design drawing, and create a three-dimensional line model of the outer contour according to the line and surface data. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0068] Step S202 , extracting outer contour graphics of a plurality of preset unit components from the outer contour three-dimensional line mold, and drawing a construction drawing of each preset unit component according to the outer contour graphics of each preset unit component.

[0069] In some optional embodiments, the preset unit element includes a deck, and the method further includes:

[0070] Step S2021, according to the preset drawing principle, the deck is used as the tread for reverse construction, and a linear tire frame drawing is drawn. The linear tire frame drawing is a construction drawing of the tire frame used to support the deck during construction.

[0071] Specifically, the preset drawing principles should be combined with the actual construction situation, and can be "low cost, high precision", which is only used as an example, but not limited to this. In the actual manufacturing and construction process of the ship-shaped pontoon, the manufacturing process of the tire frame used to support the ship-shaped pontoon often adopts the positive manufacturing method, that is, the bottom plate and the outer plate are used as the tread surface. In the positive manufacturing, the line shape of the tire frame changes greatly, and the tire frame tooth plate needs to be fitted with the hyperbolic outer plate. The drawing is difficult to express, and the manufacturing of the tire frame is difficult. In the embodiment of the present invention, the reverse manufacturing method is adopted, that is, the deck is used as the tread surface. During the manufacturing process, the hull is turned upside down with the bottom facing up. After the manufacturing is completed, the entire hull is turned over. Since the deck is relatively flat, the line shape changes little, the drawing expression is simple, and the tire frame manufacturing is simple and convenient.

[0072] Draw the line frame diagram according to the characteristics of deck surface line changes to guide the production of the line frame. Figure 8 As shown in the figure, according to the deck line change characteristics in the deck construction drawing, the required rib positions are selected on the deck as the lateral line control lines of the tire frame, and the middle longitudinal line of the deck and the outer contour edge line of the deck are selected longitudinally as the longitudinal line control lines of the tire frame. Between the floating bodies of the middle longitudinal line and the outer contour line, longitudinal line control lines can be appropriately added according to the width of the pontoon. The solid lines inside the deck are the existing control lines, and the dotted lines are the control lines added later. The intersections of the longitudinal line control lines are numbered, and the coordinate values ​​of each point are given to form an overall coordinate value table to guide the production of the line-shaped tire frame. The coordinate details of each point are shown in Table 1 below:

[0073] Table 1

[0074]

[0075]

[0076] Compared with the forward manufacturing method of using the bottom plate and outer plate as the tread, the reverse manufacturing method reduces the difficulty of the tire frame to control the line shape, facilitates the later tire frame construction, and saves the tire frame material. The linear tire frame drawing is combined with the construction drawing of the preset unit element. The bulkhead plate and rib unit are assembled and welded according to the rib position in the deck construction drawing to complete the manufacture of the "inner tube" skeleton of the ship-shaped pontoon.

[0077] The in-depth design method of the ship-shaped pontoon provided in this embodiment adopts the method of reverse manufacturing of the linear tire frame drawing, using a relatively flat deck as the tire surface, reducing the difficulty of the tire frame in controlling the linear shape, and the drawing expression is simple, which is convenient for construction and manufacturing, while saving tire frame materials. The principle of "smoothly fitting the inner tube frame" is adopted to facilitate the assembly of the outer plate.

[0078] Step S203, determine the 3D graphics of the outer panel according to the outer contour 3D line model, and disassemble the 3D graphics of the outer panel into multiple scattered units according to the preset disassembly principle. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0079] Step S204, based on the construction drawings of the preset unit components, determine the frame drawings of the scattered units, and determine the construction drawings of the scattered units according to the frame drawings of the scattered units.

[0080] Specifically, the preset unit element also includes a rib unit, and the above step S204 includes:

[0081] Step S2041, determining a plurality of rib lines according to the construction drawing of the rib unit.

[0082] Specifically, the existing rib position line is determined according to the construction drawing of the rib position unit in the construction drawing of each preset unit element and the existing rib position line is used as a reference.

[0083] Step S2042: fitting auxiliary rib bit lines between rib bit lines according to the relationship between the line type change of each scattered unit and the preset change threshold.

[0084] Specifically, each scattered unit is formed by bending a sheet steel plate. Due to the limitation of the bending process, for some hyperbolic parts, the curvature is large, that is, when the linear change of the scattered unit is greater than the preset change threshold, it cannot be bent at one time. It is necessary to fit auxiliary rib position lines between the rib position lines to minimize the linear change of the hyperbolic part and smoothly connect the rib position lines. It should be noted that the preset change threshold is determined according to the actual bending process's limit range on the change of the scattered part's shape value and the plate width of the scattered part, which will not be repeated here.

[0085] like Fig. 9 As shown in the figure, after the outer plate is disassembled and numbered as N7, according to the urgency of the line type change, rib auxiliary lines (such as FR24+100, FR24+200, FR25+100, etc.) are added between the existing rib lines (such as FR24, FR25), the spacing between adjacent rib lines or auxiliary rib lines is 100mm, and control lines (parallel lines drawn to both sides based on FR26) are set from the middle of the ship (FR26) to both sides in the ship width direction, and the spacing between the control lines is 50mm to 200mm. The intersection points of the two (grid intersection points formed by the transverse rib lines, rib auxiliary lines and the vertical middle line and its parallel control lines) are numbered, and the coordinate value of each point is given to form an overall coordinate value table to guide the production of dense tire frames. This is only an example, but not limited to this.

[0086] Step S2043, determining the tire frame diagram of each scattered unit according to each rib position line and the auxiliary rib position line.

[0087] Specifically, the line control points of the hyperbolic parts (the scattered units of the bow panel and the stern panel) are added by fitting to obtain the auxiliary rib position lines, and the frame drawings of the scattered units are formed according to the existing rib position lines and the auxiliary rib position lines. The frame drawings of the scattered units are used as processing templates to determine the construction drawings of the scattered units, so as to control the processing accuracy of the scattered units.

[0088] Step S2044, numbering the multiple scattered units according to a preset numbering principle and unfolding them one by one to obtain unfolded parts.

[0089] Specifically, the scattered units are numbered systematically according to their distribution positions, and professional software is used to unfold the scattered units of the outer panel one by one into a plane to facilitate the corresponding steel plate cutting. The unfolded parts drawing must include part number, plate thickness, quantity, material, direction, rib position line and other information to facilitate accurate use in subsequent processes.

[0090] Step S2045, determining the type value coordinate table of each unfolded part according to the jig frame diagram of each scattered unit.

[0091] Specifically, the tire frame diagram of each scattered unit includes the existing rib position line and the auxiliary rib position line. The spacing between adjacent rib position lines is 100 mm. Control lines are set from the middle of the ship to both sides in the ship width direction. The spacing between the control lines is 50 mm to 200 mm. The intersection points of the two are numbered, and the coordinate value of each point is given to form an overall coordinate type value table to guide the production of dense tire frames. The outer plate line type numbered N7 varies greatly, and the coordinate details of each point are shown in Table 2.

[0095]

[0096]

[0097]

[0098] Step S2046, determining the construction drawings of each scattered unit according to the type value coordinate table of each unfolded part.

[0099] The in-depth design method of the ship-shaped pontoon provided in this embodiment obtains a more accurate tire frame drawing of the scattered units by adding rib lines of each scattered unit, thereby improving the expression accuracy of the construction drawings of each scattered unit, facilitating the one-time bending forming of hyperbolic parts and improving production efficiency.

[0100] Step S205, assemble the construction drawings of each scattered unit to obtain the outer panel construction drawing. Figure 1 Step S105 of the illustrated embodiment will not be described in detail here.

[0101] The ship-shaped pontoon in-depth design method provided in this embodiment is easy to control the processing accuracy and quality by prefabricating the preset unit element as the preparation unit, which is conducive to improving the accuracy of the "inner tube" of the ship-shaped pontoon manufacturing. By determining the tire frame drawing of each scattered unit, the control points of the outer plate hyperbolic parts are increased, making the processing drawing of the hyperbolic parts smoother and improving the drawing expression accuracy of the hyperbolic parts. The overall linear accuracy of the ship-shaped pontoon is effectively controlled, the defect of poor appearance molding of the ship-shaped pontoon is solved, and the processing cost and actual use risk are reduced.

[0102] In this embodiment, a ship-shaped pontoon in-depth design device is also provided, which is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated.
