Description

Technical Field

[0001] The invention relates to the technical field of ship construction, and in particular to a method for assembling a ship side structure. Background Art

[0002] Aluminum alloy has material properties such as low density, high specific strength, and strong corrosion resistance. It has been widely used in the construction of ships such as high-speed boats, ocean survey ships, and fishing vessels, ensuring the structural strength, lightweight, and corrosion resistance of the ships.

[0003] The ship's side structure consists of the deck, outer plate, side damper base, fender and pipe rack. As a key component of the aluminum hull, the side structure directly bears the weight of the ship's superstructure, wave impact, water pressure and other multiple loads. Its manufacturing quality and installation accuracy play a vital role in the structural strength and stability. During the construction process, the side structure is prone to engineering problems such as large welding stress, difficult deformation control, and poor installation accuracy due to the large linear expansion coefficient of the material, special structural line shape and complex pipe rack structure, resulting in poor quality after assembly.

[0004] Therefore, a ship side structure assembly method is needed to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a method for assembling a ship side structure, which can ensure that the quality after assembly meets the requirements.

[0017] In some embodiments, in step S3, component installation lines and large closing seam lines are marked on the deck and the outer plate according to the reference line.

[0018] In some embodiments, when installing the side bracket, the side bracket connected to the longitudinal round tube of the pipe rack structure is fixed by spot welding.

[0019] In some embodiments, in step S5, a longitudinal diagonal brace reinforcement is installed at the side air door base.

[0020] In some embodiments, in step S5, the welding lifting code is used in conjunction with the lifting equipment to turn over the side structure, and the rib position positioning lines of the overall width and length of the side structure and the positioning lines of the height and width of the angle lines are marked.

[0021] In some embodiments, in step S6, a pier wood assembly tooling is set on the ground directly below the outermost frame of the side structure for support, and then the side structure is hoisted to the installation position, and the rib position positioning line and the positioning line are adjusted to correspond to the main hull.

[0042] When assembling the side structure of a ship, in order to ensure that the quality of the assembled structure meets the requirements, such as Figure 1-Figure 6 As shown, the present invention provides a method for assembling a ship side structure. The method for assembling a ship side structure comprises the following steps:

[0043] S1. Marking the assumed center line, horizontal line and rib inspection line of the tire frame 200;

[0044] S2, installing the deck 302 and the outer plate 301 on the tire frame 200, and positioning and fixing them according to the assumed center line, horizontal line and rib inspection line of the tire frame 200;

[0045] S3. Draw reference lines on the deck 302 and the outer plate 301 based on the assumed center line, horizontal line and frame inspection line;

[0046] S4. Install the transverse members 303, the longitudinal members 304, the side brackets 305, the bulk brackets 306, the bottom longitudinal members, the side damper base 312 and the fenders 307 on the deck 302 and the outer plate 301 according to the reference line to form the side structure 300;

[0047] S5. Weld and install the longitudinal reinforcement 311 and the plurality of transverse reinforcements 309 on the side structure 300, and weld the hanging bracket 308 on the side structure 300;

[0048] S6. The side structure 300 is hoisted to the installation position, and the side structure 300 is welded to the main hull 100;

[0049] S7, welding the pipe rack structure 500 on the side structure 300, and removing the longitudinal reinforcement 311 and the transverse reinforcement 309;

[0050] S8. Complete the welding of the side structure 300 and the surrounding hull structure 110.

[0051] By positioning and installing the side structure 300 on the tire frame 200 in the above manner, the side structure 300 can be assembled smoothly, and the installation of components and brackets can be guided by surveying the reference line to ensure the installation accuracy. By welding and installing the longitudinal reinforcement 311 and multiple transverse reinforcements 309 on the side structure 300, it is convenient to control the deformation, reduce the influence of welding stress, and ensure that the quality after assembly meets the requirements.

[0052] In some embodiments, in step S2, the deck 302 and the outer plate 301 are pressed and fitted to the tire frame 200 by a pressure iron, and fixed by a rotating puller. In this embodiment, the side structure 300 is constructed by the reverse manufacturing method. By reasonably designing the tire frame 200, the tire frame 200 is adapted to the design contours of the deck 302 and the outer plate 301. By pressing the deck 302 and the outer plate 301 to fit on the tire frame 200 by a pressure iron and a rotating puller, the contour shape of the deck 302 and the outer plate 301 can be accurately controlled, ensuring that the side structure 300 formed after subsequent welding and assembly meets the design requirements.

[0053] In some embodiments, in step S3, a thin steel wire is pulled at the wire frame, and the assumed center line, horizontal line and rib inspection line of the tire frame 200 are marked on the structural surface of the deck 302 and the outer plate 301 by the plumb bob method, and a reference line is marked 100 mm from the rib inspection line to the bow and 100 mm from the assumed center line of the tire frame 200 to the side. The reference line is marked in the above manner to facilitate the subsequent positioning and installation of other components of the side structure 300.

[0054] In some embodiments, in step S3, component installation lines and large closure seam lines are marked on the deck 302 and the outer plate 301 according to the reference line. By marking component installation lines and large closure seam lines, effective positioning is provided for the subsequent closure welding of the assembled side structure 300 with the main hull 100 and the surrounding hull structure 110.

[0055] In some embodiments, when installing the side bracket 305, the side bracket 305 connected to the longitudinal round tube of the pipe rack structure 500 is fixed by spot welding. Since part of the side bracket 305 has an assembly relationship with the subsequent longitudinal round tube of the pipe rack structure 500, but the installation of this part of the side bracket 305 is before the installation of the longitudinal round tube. Therefore, through the spot welding installation method, when the position of the subsequent installation of the longitudinal round tube is not suitable, the connection between the side bracket 305 and the deck 302 or the outer plate 301 can be quickly disconnected, and then adjusted to a suitable position, and full welding can be performed.

[0056] In some embodiments, when installing the transverse member 303, since the subsequent hanging weight 308 needs to be welded to the transverse member 303, the part of the transverse member 303 corresponding to the rib position where the hanging weight 308 is located is fully welded, and the transverse member 303 parts of the other rib positions are only spot welded and fixed, and then welded after the ship is positioned on the slipway. In the above manner, when the hanging weight 308 is used to turn over the side structure 300 and hoist it to cooperate with the main hull 100, it can be ensured that the hanging weight 308 is stably connected to the side structure 300 through the transverse member 303. The remaining parts are spot welded to facilitate subsequent adjustment.

[0057] In some embodiments, in step S5, a longitudinal diagonal brace reinforcement 310 is installed at the side air door base 312. By installing the longitudinal diagonal brace reinforcement 310, the strength of the side air door base 312 can be improved to prevent the side air door base 312 from being deformed during the subsequent assembly process.

[0058] In some embodiments, in step S5, the side structure 300 is turned over by using the welding hanger 308 in cooperation with the lifting equipment, and the rib position positioning lines of the overall width and length of the side structure 300 and the positioning lines of the height and width of the angle lines are marked. In the above manner, after the side structure 300 is turned over after the reverse construction is completed, the rib position positioning lines and the positioning lines of the height and width of the angle lines to be subsequently installed with the main hull 100 are marked, so as to facilitate the subsequent guidance of the installation of the side structure 300 on the main hull 100.

[0059] In some embodiments, in step S6, a pier wood assembly tooling 400 is set on the ground directly below the outermost frame of the side structure 300 for support, and then the side structure 300 is hoisted to the installation position, and the rib position positioning line and the positioning line are adjusted to correspond to the main hull 100. In this embodiment, a wedge-shaped sleeper 402 is used in conjunction with a steel pier 401 as the pier wood assembly tooling 400. By cooperating with the wedge-shaped sleeper 402 and the side structure 300, it is possible to avoid rigid contact between the side structure 300 and the pier wood assembly tooling 400, thereby protecting the side structure 300.

[0060] In some embodiments, in step S6, a reverse deformation amount is reserved for the side structure 300. Since internal stress will be generated during the subsequent welding process with the main hull 100, causing the side structure 300 to deform, the reverse deformation amount is reserved to offset the deformation caused by the internal stress after the subsequent welding is completed.

[0061] In some embodiments, in step S6, the hull structure within the range of 0-300 mm from the large closure seam line is only spot welded and assembled, and full welding is performed after the berth is closed and positioned. After the spot welding assembly, the hull structure is then closed and positioned and then fully welded. During the closing and connecting process, the hull structure can be adjusted at any time as needed.

[0062] In some embodiments, in step S7, the manufacturing process of the pipe rack structure 500 is as follows:

[0063] The A pipe 501, the B pipe 502, the C pipe 503, the first bracket and the supporting reinforcement material in the pipe rack structure 500 are first assembled into an A-type pipe rack structure, and the D pipe 504, the second bracket and the sealing plate are assembled into a bulk pipe rack structure, and then the A-type pipe rack structure and the bulk pipe rack structure are assembled to form the pipe rack structure 500. The above method facilitates the assembly of the pipe rack structure 500. After the multiple pipe rack structures 500 are welded and installed on the side structure 300, the longitudinal round pipes are installed, and the multiple A-type pipe rack structures are connected by the longitudinal round pipes to ensure the overall structural strength.

[0064] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
