Description

Technical Field

[0001] This application relates to the field of ship depth sounding devices, and in particular to a plate assembly for a ship hull and a method for assembling the plate assembly. Background Technology

[0002] The hull assembly includes ribs and main plates, both of which are common components in existing ships. Current assembly methods for hull assemblies typically employ either an insertion method or a pull-in method. The insertion method involves first assembling and welding the longitudinal ribs on the main plate, then pre-setting "open" through holes at the ribs, and finally inserting the ribs into their corresponding positions. Because the gap between the "open" through holes and the longitudinal ribs is relatively large, supplementary plates need to be placed in the through holes to form temporary supports, ultimately completing the assembly of the hull assembly. Therefore, using the insertion method results in a large amount of supplementary plate processing, assembly, and welding, leading to a long manufacturing cycle.

[0003] The pull-in method involves first assembling and welding the longitudinal ribs on the main board, then pre-setting "closed" through holes at the ribs. The ribs are then pulled from the edge of the main board along the longitudinal ribs to the corresponding positions before welding, thus completing the assembly of the board assembly. However, this method requires high precision control and is limited to flat areas such as the inner bottom, inner shell, sloping bottom plate, and sloping top plate. If the number of longitudinal ribs exceeds seven, pulling in the ribs becomes difficult, and the middle area needs to be cut and enlarged again. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a plate assembly for a ship hull and a method for assembling the plate assembly, so as to solve the problems of long manufacturing cycle of the existing insertion method and high precision control requirements of the pull-in method.

[0005] In accordance with the above objectives, a first aspect of the present invention provides a plate assembly for a ship hull, wherein the plate assembly for the ship hull comprises:

[0006] The motherboard has multiple longitudinal ridges;

[0007] The rib plate is connected to the longitudinal bone via an assembly part; the assembly part includes a plurality of first connecting holes and a plurality of second connecting holes, the first connecting holes being formed into a T-shaped structure corresponding to the longitudinal bone, and the second connecting holes being formed into an inverted L-shaped structure.

[0008] Preferably, each of the longitudinal ribs extends along the length direction of the main board, and the plurality of longitudinal ribs are spaced apart along the width direction of the main board.

[0009] Preferably, the cross-section of the longitudinal bone is formed into a T-shaped structure; the flatness of the longitudinal bone within every two meters is within ±1.0 mm, the straightness of the longitudinal bone within every two meters is within ±1.0 mm, and the verticality deviation of the longitudinal bone is within ±1.5 mm.

[0010] Preferably, there are multiple ribs, which are spaced apart along the length of the main board; the extension direction of each rib is the same as the width direction of the main board.

[0011] Preferably, when the rib is assembled with the motherboard, the rib is perpendicular to the motherboard and the first connecting hole and the second connecting hole are formed at the bottom end of the rib.

[0012] Preferably, the plurality of first connecting holes are located at the center of the length direction of the rib plate, and the plurality of first connecting holes are arranged at intervals along the length direction of the rib plate.

[0013] Preferably, when the rib is assembled with the main board, a gap is formed between the inner wall of the vertical section of the first connecting hole and the outer wall of the vertical section of the longitudinal bone; when the number of the first connecting holes is less than seven, the gap is 2.5 mm; when the number of the first connecting holes is not less than seven, the gap is 3.0 mm.

[0014] Preferably, a plurality of second connecting holes are disposed at both ends of the rib plate along its length.

[0015] Preferably, the flatness of the motherboard is within ±3.0mm.

[0016] According to a second aspect of the present invention, a plate assembly method is provided, applicable to the plate assembly for a ship hull as described above, wherein the plate assembly method includes the following steps:

[0017] S10: Check whether the dimensions of the main board and the rib plate meet the process standards.

[0018] S20: Use a crane to lift the rib plate, and with the help of a winch, a pulley, and an oil pump, insert the longitudinal bone of the main board into the first connecting hole and the second connecting hole of the rib plate; at the same time, move the crane to pull the rib plate in.

[0019] According to the present invention, the plate assembly for ship hull and the plate assembly assembly method are used to assemble the rib plate and the main plate by providing a first connecting hole that corresponds to and matches the longitudinal bone structure and a second connecting hole formed in an "inverted L" shape (the second connecting hole has a larger gap with the longitudinal bone) at the rib plate. In this way, the number of patch plates can be effectively reduced by the first connecting hole, and the accuracy requirements can be effectively reduced by the second connecting hole, thereby reducing the assembly difficulty.

[0033] According to a first aspect of the present invention, a plate assembly for a ship hull is provided, such as Figure 1 As shown, the hull plate assembly of this embodiment includes a main plate 1 and a rib plate 2. The rib plate 2 has a mounting portion that allows it to be assembled with the main plate 1. The specific structure of the above-described assembly of the hull plate assembly according to the present invention will be described in detail below.

[0034] In this embodiment, the main board 1 is formed as a cuboid plate structure, with a plurality of longitudinal ribs 10 formed at its top end in the thickness direction. Each longitudinal rib 10 extends along the length direction of the main board 1, and the plurality of longitudinal ribs 10 are spaced apart along the width direction of the main board 1. Preferably, the flatness of the main board 1 is within ±3.0 mm.

[0035] Furthermore, such as Figure 1 As shown, the cross-section of the longitudinal rib 10 in this embodiment is formed into a T-shaped structure. In order to ensure the stability and assembly accuracy of the overall structure of the plate assembly, the flatness of the longitudinal rib 10 within every two meters should be controlled within ±1.0mm, the straightness of the longitudinal rib 10 within every two meters should be controlled within ±1.0mm, and the verticality deviation of the longitudinal rib 10 should be controlled within ±1.5mm.

[0036] Furthermore, in this embodiment, there are multiple ribs 2, which are spaced apart along the length direction of the main board 1; the extending direction of each rib 2 is the same as the width direction of the main board 1. Figure 1 As shown, each rib 2 has a mounting portion that can be connected to the longitudinal rib 10, thereby enabling the rib 2 to be connected to the main plate 1. Specifically, the mounting portion includes multiple first connecting holes 21 and multiple second connecting holes 22. The first connecting holes 21 are formed into a T-shaped structure corresponding to the longitudinal rib 10, and the second connecting holes 22 are formed into an inverted L-shaped structure. When the rib 2 is assembled with the main plate 1, the rib 2 is perpendicular to the main plate 1, and the first connecting holes 21 and the second connecting holes 22 are formed at the bottom end of the rib 2. Furthermore, to facilitate the corresponding assembly of the rib 2 and the main plate 1, both the first connecting holes 21 and the second connecting holes 22 penetrate through the bottom end of the rib 2.

[0037] More specifically, a plurality of first connecting holes 21 are located at the center of the longitudinal direction of the rib plate 2, and the plurality of first connecting holes 21 are arranged at intervals along the longitudinal direction of the rib plate 2. The horizontal section of the first connecting hole 21 forms a large gap with the horizontal section of the longitudinal bone 10, but the vertical section (inner wall) of the first connecting hole 21 forms a small gap with the vertical section (outer wall) of the longitudinal bone 10. This facilitates the corresponding connection between the first connecting hole 21 and the longitudinal bone 10 while avoiding the need for additional plates. Preferably, when the number of first connecting holes 21 is less than seven, the gap between the vertical section of the first connecting hole 21 and the vertical section of the longitudinal bone 10 is 2.5 mm; when the number of first connecting holes 21 is not less than seven, the gap between the vertical section of the first connecting hole 21 and the vertical section of the longitudinal bone 10 is 3.0 mm.

[0038] In addition, the second connecting hole 22 is provided at both ends of the rib plate 2 in the opposite direction of its length. In this embodiment, the second connecting hole 22 is formed into an inverted L-shaped structure, so that it forms a large gap with the longitudinal bone 10, which can improve the assembly efficiency of the plate assembly.

[0039] It should be noted that there are no specific limitations on the number of ribs 2, the number of longitudinal ribs 10, and their spacing. These should be determined comprehensively based on actual conditions such as hull specifications, as long as the aforementioned technical effects can be achieved to ensure the stability of the overall hull structure. In addition, the aforementioned ribs 2 are also provided with lifting holes 20 to facilitate the connection of lifting equipment.

[0040] According to the present invention, the plate assembly for a ship hull and the plate assembly assembly method are used to assemble the rib plate 2 and the main plate 1 by providing a first connecting hole 21 corresponding to the structure of the longitudinal rib 10 and a second connecting hole 22 formed in an inverted L-shape (the second connecting hole 22 has a larger gap with the longitudinal rib 10) at the rib plate 2. In this way, the number of patch plates can be effectively reduced by the first connecting hole 21, and the precision requirements can be effectively reduced by the second connecting hole 22, thereby reducing the assembly difficulty. With the above structure, when assembling the rib plate 2 and the main plate 1, the advantages of the pull-in method can be utilized to improve assembly efficiency, while the requirements for precision control are reduced, effectively reducing the difficulty of on-site assembly.

[0041] According to a second aspect of the present invention, a plate assembly method is provided, applicable to the plate assembly for a ship hull as described above, wherein the plate assembly method includes the following steps:

[0042] S10: Check whether the dimensions of the main board 1 and the rib plate 2 meet the process standards.

[0043] S20: Use a crane to lift the rib plate 2, and with the help of a winch, a pulley, and an oil pump, insert the longitudinal bone 10 of the main board 1 into the first connecting hole 21 and the second connecting hole 22 of the rib plate 2; at the same time, move the crane to pull the rib plate 2 in.

[0044] It should be noted that in step S10 above, the assembly personnel must strictly adhere to the intervals between various dimensional data. Furthermore, the measured data can be recorded at the web of the longitudinal rib 10 to ensure the smooth pulling of the rib plate 2. In addition, deformation of the rib plate 2 should be avoided when the overhead crane is used to transport it. If the rigidity of the rib plate 2 is insufficient, it can be reinforced using special tooling such as channel steel.

[0045] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can still modify or easily conceive of changes to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features, within the technical scope disclosed in this application. Such modifications, changes, or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be defined by the protection scope of the claims.
