Description

Technical Field

[0001] The present application relates to the field of ship depth sounding devices, and in particular to a plate assembly for a ship body and a plate assembly assembly method. Background Art

[0002] The plate assembly includes ribs and main boards, both of which are common components of existing ships. The existing assembly methods of plate assemblies usually adopt the insertion method or the pull-in method. The insertion method refers to first assembling and welding the longitudinal bones on the main board, and presetting an "open" through hole at the rib plate, and then hoisting the rib plate to the corresponding position for insertion. Since the gap between the "open" through hole and the longitudinal bone is large, it is necessary to set a patch plate in the through hole to form a temporary support, and finally complete the assembly of the plate assembly. It can be seen that the use of the insertion method will bring a large amount of patch plate processing, assembly, and welding, and the production cycle is long.

[0003] The pull-in method means that the longitudinal bones are first assembled and welded on the main board, and a "closed" through hole is preset at the rib plate. The rib plate is pulled in from the edge of the main board along the longitudinal bones to the corresponding position and then welded to complete the assembly of the plate assembly. However, this method has high requirements for precision control and its application is limited to straight areas such as the inner bottom, inner shell, inclined bottom plate, and inclined top plate. If the number of longitudinal bones exceeds seven, it is difficult to pull the rib plate in, and the middle area needs to be cut and expanded again. Summary of the invention

[0004] In view of this, the purpose of the present application is to provide a plate assembly for a ship body and a plate assembly assembly method to solve the problem that the existing insertion method has a long production cycle and the pull-in method has high requirements for precision control.

[0005] According to the above purpose, the first aspect of the present invention provides a plate assembly for a hull, wherein the plate assembly for a hull comprises:

[0006] a main plate, formed with a plurality of longitudinal bones;

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

[0008] Preferably, each of the longitudinal bones extends along the length direction of the main board, and a plurality of the longitudinal bones are spaced apart and distributed 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 a plurality of ribs, and the ribs are spaced apart along the length direction of the main board; and the extending direction of each rib is the same as the width direction of the main board.

[0011] Preferably, when the rib plate is assembled correspondingly to the main board, the rib plate is perpendicular to the main board and the first connection hole and the second connection hole are formed at the bottom end of the rib plate.

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

[0013] Preferably, when the rib plate is assembled correspondingly to 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 formed to 2.5 mm; when the number of the first connecting holes is not less than seven, the gap is formed to 3.0 mm.

[0014] Preferably, a plurality of second connection holes are arranged at both ends of the rib plate in the length direction.

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

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

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

[0019] According to the plate assembly for a ship body and the plate assembly assembly method of the present invention, the rib plate and the main board are assembled by providing a first connecting hole corresponding to the longitudinal bone structure and a second connecting hole formed in an "inverted L" shape structure (the second connecting hole has a larger gap with the longitudinal bone). In this way, the number of supplementary plates can be effectively reduced through the first connecting hole, and the requirement for precision can be effectively reduced through the second connecting hole, thereby reducing the difficulty of assembly.

[0033] According to a first aspect of the present invention, there is provided a panel assembly for a ship, such as Figure 1 As shown, the plate assembly for the hull of this embodiment includes a main plate 1 and a rib plate 2, and the rib plate 2 is formed with an assembly portion so that it can be assembled with the main plate 1 through the assembly portion. Hereinafter, the specific structure of the above-mentioned components of the plate assembly for the hull according to the present invention will be described in detail.

[0034] In this embodiment, the main board 1 is formed into a rectangular plate-like structure, and a plurality of longitudinal bones 10 are formed at the top end in the thickness direction, each of the longitudinal bones 10 extends along the length direction of the main board 1, and the plurality of longitudinal bones 10 are distributed at intervals along the width direction of the main board 1. Preferably, the flatness of the main board 1 is within ±3.0 mm.

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

[0036] In addition, the number of ribs 2 in this embodiment is multiple, and the multiple ribs 2 are spaced apart along the length direction of the main board 1; the extension direction of each rib 2 is the same as the width direction of the main board 1. Figure 1 As shown, each rib plate 2 is formed with an assembly portion, which can be connected to the longitudinal bone 10, so that the rib plate 2 can be connected to the main board 1. Specifically, the assembly portion includes a plurality of first connection holes 21 and a plurality of second connection holes 22, the first connection holes 21 are formed into a T-shaped structure corresponding to the longitudinal bone 10, and the second connection holes 22 are formed into an "inverted L"-shaped structure. When the rib plate 2 is assembled with the main board 1, the rib plate 2 is perpendicular to the main board 1 and the first connection hole 21 and the second connection hole 22 are formed at the bottom end of the rib plate 2; in addition, in order to facilitate the corresponding assembly of the rib plate 2 and the main board 1, the first connection hole 21 and the second connection hole 22 both pass through the bottom end of the rib plate 2.

[0037] More specifically, the plurality of first connection holes 21 are located at the center of the length direction of the rib plate 2, and the plurality of first connection holes 21 are arranged at intervals along the length direction of the rib plate 2. A large gap is formed between the horizontal section of the first connection hole 21 and the horizontal section of the longitudinal bone 10, but a small gap is formed between the vertical section (the inner wall) of the first connection hole 21 and the vertical section (the outer wall) of the longitudinal bone 10, so that the corresponding connection between the first connection hole 21 and the longitudinal bone 10 is convenient and the situation of adding a supplementary plate can be avoided. Preferably, when the number of the first connection holes 21 is less than seven, the gap between the vertical section of the first connection hole 21 and the vertical section of the longitudinal bone 10 is formed to be 2.5 mm; when the number of the first connection holes 21 is not less than seven, the gap between the vertical section of the first connection hole 21 and the vertical section of the longitudinal bone 10 is formed to be 3.0 mm.

[0038] In addition, the second connecting holes 22 are arranged at the two ends of the rib plate 2 in opposite directions of length. In this embodiment, the second connecting holes 22 are formed into an "inverted L" shape structure, so that a larger gap is formed between them and the longitudinal bone 10, thereby improving the assembly efficiency of the plate assembly.

[0039] It should be noted that there is no specific limitation on the number of the ribs 2, the number of the longitudinals 10, and the spacing, etc., which should be determined based on the actual situation, such as the hull specifications, as long as the above technical effects can be achieved to ensure the stability of the overall structure of the hull. In addition, the ribs 2 are also provided with hoisting holes 20 for facilitating the connection of a hoisting device.

[0040] According to the plate assembly and plate assembly assembly method for the ship body of the present invention, the rib plate 2 is assembled with the main board 1 by providing a first connection hole 21 corresponding to the longitudinal bone 10 structure and a second connection hole 22 formed in an "inverted L" shape (the second connection hole 22 has a larger gap with the longitudinal bone 10) at the rib plate 2, so that the number of patch plates can be effectively reduced through the first connection hole 21, and the requirements for precision can be effectively reduced through the second connection hole 22, thereby reducing the difficulty of assembly. Through the above structure, when assembling the rib plate 2 and the main board 1, the advantages of the pull-in method can be brought into play to improve the 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, there is provided a plate assembly method, which is applicable to the plate assembly for a ship as described above, wherein the plate assembly method comprises the following steps:

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

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

[0044] It should be noted that in the above step S10, the assembler needs to strictly space the various dimensional data. Furthermore, the measured data can be recorded at the web of the longitudinal bone 10 to ensure the smooth pulling in of the rib plate 2. In addition, when the rib plate 2 is hoisted by a crane, deformation of the rib plate 2 should be avoided. If the rigidity of the rib plate 2 is insufficient, it can be strengthened by special tooling such as channel steel.

[0045] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be described in the protection scope of the claims.
