[0002] Based on the requirements of ship performance and overall mechanical performance, the structural forms and nodes of ships in different regions vary. The scientific and effective transition of structures between regions can ensure that the structures in each region meet the requirements of ship layout, specifications, strength, etc., while ensuring that the transition areas are convenient for production and construction.

[0003] In related technologies, the bottom side compartment area of ​​ships often adopts a three-point aligned inclined cross joint structure for the sloping top plate, inner bottom plate, and longitudinal girder, with a transition structure between the arc plate and the inclined cross joint. However, the precision and stress resistance of ships manufactured using the above structures are relatively poor. Summary of the Invention

[0004] In view of this, this application provides a ship structure. The ship structure can improve the precision and structural strength of the ship during the construction process.

[0005] This application provides a ship structure, including:

[0006] Connector assembly;

[0007] A connecting assembly, one side of which is connected to the joint assembly, the connecting assembly comprising: a first transition plate and a second transition plate; the first transition plate and the second transition plate are corner-connected; both the first transition plate and the second transition plate have edge lines.

[0008] An arc-shaped plate, one side of which is connected to the side of the connecting assembly away from the joint assembly.

[0009] In some embodiments, the first transition plate has a first side line, a second side line, a third side line, and a fourth side line, the connection between the second transition plate and the arc-shaped plate is the first side line, and the first side line is collinear with the stern edge of the arc-shaped plate.

[0010] In some embodiments, the third edge line is collinear with the bow edge of the inner bottom plate.

[0011] In some embodiments, the second transition plate has a fifth side line, a sixth side line, a seventh side line, and an eighth side line. The fifth side line is collinear with the stern edge of the arc-shaped plate. The sixth side line is collinear with the second side line, and both the fifth side line and the arc-shaped plate have an arc of R600.

[0012] In some embodiments, the connector assembly includes: a first connecting portion and a second connecting portion arranged sequentially, with a baffle disposed between the first connecting portion and the second connecting portion; the second connecting portion is connected to the connecting assembly.

[0013] In some embodiments, the first connecting portion includes: a first elbow plate and a second elbow plate;

[0014] The first elbow plate is disposed along a first direction, and the second elbow plate is disposed along a second direction, wherein the first direction and the second direction intersect.

[0015] In some embodiments, the second connecting portion includes: an inner bottom plate, a sloping top plate, and a longitudinal truss plate;

[0016] The longitudinal truss is disposed on the inner bottom plate, and the inclined top plate is fixedly disposed on the longitudinal truss. There is an angle α between the inner bottom plate and the longitudinal truss, and an angle b between the inclined top plate and the longitudinal truss. The angle b is greater than the angle α.

[0017] In some embodiments, the included angle α ranges from 70° to 90°.

[0018] In some embodiments, the included angle b ranges from 70° to 90°.

[0019] This application also discloses a method for processing a ship structure, used to process the aforementioned ship structure, comprising:

[0020] Prepare the first transition plate according to the processing type, leaving a margin;

[0021] Use materials to build a circular model of the ship, and set the baseline and fold lines on the baseline according to the drawings;

[0022] Prototype boxes were manufactured and processed based on the ship's circular model;

[0023] The excess material is cut off, and the errors of each component are matched according to the processing sample box.

[0024] In this application, the first and second transition plates of the ship structure are set as curved surfaces, which can ensure the accuracy and tolerance requirements of the joint assembly and the arc plate after connection, and can also reduce the workload of production, assembly and construction. At the same time, it can also reduce the amount of welding, thereby reducing the fatigue effect of welding on the plate and the weight effect caused by the thickness, and thus reducing the weight of the ship.

[0025] Understandably, the connecting assembly is used to connect the joint assembly and the curved plate. The connecting assembly includes a first transition plate and a second transition plate, which are corner-connected, meaning there is an included angle between the surfaces of the first and second transition plates. Both the first and second transition plates have connecting edges at their connection points. These connecting edges enable the structure of the first and second transition plates after connection to adapt to the curved plate. This improves the overall integrity of the curved plate and the connecting assembly after connection, reducing the connection surface and thus the welding surface. After connection, the curved plate and the connecting assembly have only two welding surfaces (i.e., opposing front and back surfaces), thereby improving the mechanical properties of the connecting assembly and the curved plate after connection. Furthermore, the curved plate and the connecting assembly form opposing planes after connection, further enhancing their mechanical properties and giving them greater structural strength compared to structures in related technologies.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0040] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

They can refer to a direct connection or an indirect connection through an intermediate medium, and they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0043] Based on the requirements of ship performance and overall mechanical performance, the structural forms and nodes of ships in different regions vary. The scientific and effective transition of structures between regions can ensure that the structures in each region meet the requirements of ship layout, specifications, strength, etc., while ensuring that the transition areas are convenient for production and construction.

[0044] In related technologies, the bottom side compartment area of ​​ships often adopts a three-point aligned inclined cross joint structure for the sloping top plate, inner bottom plate, and longitudinal girder, with a transition structure between the arc plate and the inclined cross joint. However, the precision and stress resistance of ships manufactured using the above structures are relatively poor.

[0045] The three-point aligned inclined cross joint structure is a structure in which the inclined top plate and the inner bottom plate are directly rounded into an arc plate and cornered with the longitudinal girder. This processing method has high requirements for processing tolerances, and most areas need to be connected by welding, which will lead to a decrease in the fatigue strength of the material. In order to reduce the impact of the reduced fatigue strength due to welding, steel plates are connected at the weld to strengthen its structural strength, resulting in an increase in the weight of the ship.

[0046] Therefore, this embodiment provides a ship structure 100. The ship structure 100 can improve the accuracy and structural strength of the ship during the construction process.

[0047] Please see Figure 1 A ship structure 100, comprising:

[0048] Connector assembly 11;

[0049] A connecting component 13 is provided, one side of which is connected to the connector component 11. The connecting component 13 includes a first transition plate 132 and a second transition plate 131. The first transition plate 132 and the second transition plate 131 are corner-connected. Both the first transition plate 132 and the second transition plate have connecting edges.

[0050] An arc-shaped plate, one side of which is connected to the side of the connecting assembly 13 away from the joint assembly 11.

[0051] In this application, the ship structure 100 is configured with the first transition plate 132 and the second transition plate 131 as curved surfaces, which can ensure the accuracy and tolerance requirements of the joint assembly 11 and the arc plate after connection, and can also reduce the workload of production assembly and construction, as well as reduce the amount of welding, thereby reducing the fatigue effect of welding on the plate and the weight effect caused by the thickness, and thus reducing the weight of the ship.

[0052] Understandably, the connecting component 13 is used to connect the joint component 11 and the arc-shaped plate. The connecting component 13 includes a first transition plate 132 and a second transition plate 131. The first transition plate 132 and the second transition plate 131 are corner-connected, that is, there is an included angle between the surface of the first transition plate 132 and the surface of the second transition plate 131. Both the first transition plate 132 and the second transition plate 131 have connecting edges, which are located at the connection point of the first transition plate 132 and the second transition plate 131. The connecting edges enable the structure of the first transition plate 132 and the second transition plate 131 after connection to be compatible with the arc-shaped plate. This adaptation improves the overall integrity of the curved plate and connecting component 13 after connection, reducing the connection surface and welding surface during welding. This results in only two welding surfaces (i.e., opposing front and back sides) after connection, thereby enhancing the mechanical properties of the connecting component 13 and the curved plate. Furthermore, the curved plate and connecting component 13 form a single opposing plane after connection, further improving their mechanical properties and giving them greater structural strength compared to structures in related technologies.

[0053] Please see Figure 3 In some embodiments, the first transition plate 132 has a first edge line 1311, a second edge line 1312, a third edge line 1313 and a fourth edge line 1314, and the connection between the second transition plate 131 and the arc-shaped plate is the first edge line 1311, which is collinear with the stern edge of the arc-shaped plate.

[0054] The first transition plate 132 has a first edge 1311, a second edge 1312, a third edge 1313, and a fourth edge 1314. Specifically, the first edge 1311 is the first transition plate 132 as shown in the figure. Figure 3 The right-hand sideline shown, the second sideline 1312 is as follows Figure 3 The upper edge line shown, the third edge line 1313 is as follows Figure 3 The left-hand sideline shown, the fourth sideline 1314 is as follows Figure 3 The lower edge line is shown. The first edge line 1311 is collinear with the stern edge of the curved plate. This improves the flatness of the curved plate and the first transition plate 132 after connection. The first edge line 1311 has a curvature to match the curvature of the curved plate, so that the curved plate and the first transition plate 132 are on the same plane after connection. This reduces the relative tolerance between the curved plate and the first transition plate 132 during connection, making it easier to weld the first transition plate 132 and the curved plate. At the same time, it also ensures that the first transition plate 132 and the curved plate are a whole after connection, which can improve the structural strength of the two after connection.

[0055] The second edge line 1312 is the edge line at the connection between the first transition plate 132 and the second transition plate 131. The starting point of the second edge line 1312 is at the first fold line of the arc-shaped plate, and its ending point is the intersection of the inclined top plate 111, the inner bottom plate 112, and the truss. For details, please refer to [link to relevant documentation]. Figure 3 .

[0056] Please see Figure 3 In some embodiments, the third edge line 1313 is collinear with the front edge of the inner bottom plate 112.

[0057] Understandably, the collinearity of the third edge 1313 with the bow edge of the inner bottom plate 112 allows the original point connection between the inner bottom plate 112 and the first transition plate 132 to gradually become a surface connection. This allows force to be transferred to the entire first transition plate 132, thereby improving the structural strength of the first transition plate 132 after the connection. The fourth edge 1314 does not participate in the connection, therefore no restrictions are placed on the fourth edge 1314.

[0058] Please see Figure 8 In some embodiments, the second transition plate 131 has a fifth edge line 1321, a sixth edge line 1322, a seventh edge line 1323, and an eighth edge line 1324. The fifth edge line 1321 is collinear with the stern edge of the arc-shaped plate. The sixth edge line 1322 is collinear with the second edge line 1312. The fifth edge line 1321 and the arc-shaped plate both have an arc, which is R600.

[0059] Understandably, the fifth edge 1321 of the second transition plate 131 is as follows: Figure 3 As shown on the right, the sixth side line 1322 is as follows Figure 3 As shown below, the seventh side line 1323 is as follows Figure 3 As shown on the left, the eighth side line 1324 is as follows Figure 8 The upper side is shown; wherein the fifth edge line 1321 is collinear with the stern edge of the arc plate, that is, the side of the arc plate close to the second transition plate 131 is collinear, and the fifth edge line 1321 has an arc. The arc of the fifth edge line 1321 is to match the arc of the arc plate, so that the arc plate and the second transition plate 131 are on the same plane after being connected, reducing the relative tolerance between the arc plate and the second transition plate 131 when connected, making it easier to weld the second transition plate 131 and the arc plate, and also ensuring that the second transition plate 131 and the arc plate are a whole after being connected, which can improve the structural strength of the two after being connected.

[0060] Please see Figures 1 to 6In some embodiments, the connector assembly 11 includes a first connecting portion and a second connecting portion arranged sequentially, with a baffle 114 disposed between the first connecting portion and the second connecting portion; the second connecting portion is connected to the connecting assembly 13.

[0061] Understandably, the joint assembly 11 includes a first connecting portion and a second connecting portion, and a baffle 114 (actually a transverse bulkhead) is disposed between the first connecting portion and the second connecting portion; wherein, the first connecting portion is used to connect with the main body of the ship, and the second connecting portion is connected with the connecting assembly 13. The bow end of the joint assembly 11 is used to connect with the hull or other parts of the ship.

[0062] In some embodiments, the first elbow plate 116 is disposed along a first direction, and the second elbow plate 117 is disposed along a second direction, wherein the first direction intersects the second direction.

[0063] Understandably, the first elbow plate 116 and the second elbow plate 117, the first elbow plate 116 along the first direction (e.g. Figure 2 The second elbow plate 117 is set along the second direction (as shown in the planar direction), and is positioned in the second direction (e.g., the planar direction). Figure 2 As shown in the direction perpendicular to the plane, the first elbow plate 116 and the second elbow plate 117 can be set perpendicular to each other, or they can be set at a certain angle. The first elbow plate 116 can pass through the second elbow plate 117, or the second elbow plate 117 can pass through the first elbow plate 116. After the first elbow plate 116 and the second elbow plate 117 are connected, they form a cross-shaped structure as shown in the figure. The first elbow plate 116 and the second elbow plate 117 are mainly used to strengthen the structural strength of the joint assembly 11 and the hull after connection.

[0064] In some embodiments, the second connecting portion includes: an inner bottom plate 112, an inclined top plate 111, and a longitudinal truss plate 113;

[0065] The longitudinal truss 113 is disposed on the inner bottom plate 112, and the inclined top plate 111 is fixedly disposed on the longitudinal truss 113. The inner bottom plate 112 and the longitudinal truss 113 have an included angle α, and the inclined top plate 111 and the longitudinal truss 113 have an included angle b, wherein the included angle b is greater than the included angle α.

[0066] Understandably, the second connecting part includes an inner bottom plate 112 (the structure of the inner bottom plate 112 is as follows) Figure 5As shown, the inclined top plate 111 and the longitudinal truss plate 113 are connected. The longitudinal truss plate 113 is set on the inner bottom plate 112, and the inclined top plate 111 is set on the longitudinal truss plate 113. After the longitudinal truss plate 113 and the inner bottom plate 112 are connected, an angle α is formed between their plate surfaces. The angle α can be adjusted as needed and is mainly used to support the longitudinal truss plate 113. The inner bottom plate 112 is set on the longitudinal truss plate 113, and the inner bottom plate 112 and the longitudinal truss plate 113 are also connected, forming an angle b. The angle b is mainly used to transfer force to the first transition plate 132 and / or the second transition plate 131. Therefore, the angle b can be adjusted according to the connection angle between the second transition plate 131 and the first transition plate 132.

[0067] In some embodiments, the included angle α ranges from 70° to 90°.

[0068] Understandably, the angle α mentioned above can be 70°, 75°, 80°, 85°, 90°, or other angles. Under normal circumstances, the angle between the longitudinal girder 113 and the inner bottom plate 112 can be 90°. However, in some cases, it needs to be adjusted according to the specific structure of the cabin. In order to ensure its strength after being connected to the hull structure, the range of the angle is limited to between 70° and 90°.

[0069] In some embodiments, the included angle b ranges from 70° to 90°.

[0070] Understandably, the angle of the included angle b can be 70°, 75°, 80°, 85°, 90° or other angles. The angle between the inner bottom plate 112 and the longitudinal truss plate 113 after connection depends on the angle of the first transition plate 132 and / or the second transition plate 131. Therefore, the angle of the included angle b needs to be determined based on the first transition plate 132 and the second transition plate 131.

[0071] Please see Figure 8 This application also discloses a method for processing a ship structure 100, used to process the ship structure 100, comprising:

[0072] Prepare the first transition plate 132 according to the processing type, leaving a margin;

[0073] Use materials to build a circular model of the ship, and set the baseline and fold lines on the baseline according to the drawings;

[0074] 200 sample boxes were manufactured based on the ship's circular model.

[0075] Cut off the excess material and match the error of each component according to the processing sample box 200.

[0076] Understandably, the first transition plate 132 is prepared according to the processing type, with a margin allowed. Specifically, before processing, a 100mm processing margin is ensured at the first edge line 1311 of the second transition plate 131. At the same time, it is necessary to ensure that the second edge line 1312 is straight during processing. An additional 10mm margin is added at the third edge line 1313 of the second transition plate 131. When the second transition plate 131 is connected to the inner bottom plate 112, any deviations in production accuracy can be adjusted appropriately.

[0077] A ship rotation model is constructed using materials. Reference lines and fold lines are set on the reference lines as shown in the drawings. On the second transition plate 131, the first reference line 1317, the second reference line 1318, the third fold line 1315, and the fourth fold line 1316 are respectively set. The specific locations of the first reference line 1317, the second reference line 1318, the third fold line 1315, and the fourth fold line 1316 are as follows: Figure 3 and Figure 7 As shown. The first reference line 1317 and the second reference line 1318 are the reference lines required during processing; the third folding line 1315 and the fourth folding line 1316 are to facilitate the processing of the fifth edge line 1321 into an arc shape that matches the arc plate.

[0078] A machining template box 200 is fabricated based on a ship's circular model. The machining template box 200 is a box-shaped structure composed of multiple surfaces. It consists of a stern end face 21, a bow end face 22, an inner end face 23, an outer end face 24, a top end face 25, a mid-face face 26, and a reference face 27. The mid-face face 26 is located in the center of the machining template box 200. The machining template box 200 can be understood as the ship's hull; after machining each component, placing them into the machining template box 200 allows for verification of the tolerances of each component during machining.

[0079] The excess material is trimmed, and the errors of each component are matched according to the processing template 200; the second transition plate 131 is processed, and the processing template 200 is used for comparison; the second transition plate 131 is matched with the base surface to check the line matching degree; the matching of the second transition plate 131 with the first datum line 1317 is checked; the matching of the second transition plate 131 with the second datum line 1318 is checked; after the second transition plate 131 is processed, it can be verified by placing the second transition plate 131 into the processing template 200. When the tolerance of the second transition plate 131 does not match that of the processing template 200, the excess of the second transition plate 131 is trimmed.
