Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and in particular to a method for mounting an insert-type assembly. Background Technology

[0002] In modern shipbuilding, the hull is divided into several sections that are manufactured first. After the sections are completed, they are assembled in the slipway (dock). For pillars and connecting bridge areas, they are generally assembled into R-shaped sections to shorten the hoisting and welding time in the slipway (dock) and improve construction efficiency.

[0003] When merging an R-shaped insert-type main section with an adjacent main section, the lifting status of the main section hoisting equipment is critical. If the hoisting section's posture is not ideal, adjacent main sections may fail to insert, requiring the main section to be lowered to the ground and the lengths of the four steel wire ropes to be readjusted, wasting significant installation time. Furthermore, interference between the main section and the sheet metal during insertion may occur, preventing insertion and necessitating the removal of the structure at the merging point, posing safety hazards and wasting installation time. Additionally, the main section may not be inserted horizontally, affecting the determination of margins and surveying. Therefore, a method for installing insert-type main sections is needed to address these issues. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a method for mounting an insert-type assembly section, which can predict the location of the dismantled structure in advance, reduce the time required for dismantling and reassembling the structure, save time, and achieve rapid mounting.

[0005] Based on this, the present invention provides a method for mounting an insert-type assembly, which includes the following steps:

[0006] S1. Confirm the hoisting status of the insert-type main section to be assembled;

[0007] S2. Remove the protruding structure at the end of the insert-type main section to be assembled;

[0008] S3. Hoist the insertion section and adjust the length of the wire rope of the insertion section to achieve the hoisting state described in step S1.

[0009] S4. The insert-type main section is erected on the submerged body section and connected to the submerged body section;

[0010] S5. Align the insert-type section along the side of the deck, and insert the protruding structure of the insert-type section to be assembled into the positioned insert-type section to complete the connection between the insert-type section to be assembled and the positioned insert-type section.

[0011] S6. Measure the condition of the insert-type assembly section to be assembled, confirm the margin and cut it;

[0012] S7. Align several insertable sections along the sides of the deck with the width of the deck, and repeat steps S5 and S6.

[0013] S8. Position and adjust the insert-type main section to be assembled, and then weld the insert-type main section to be assembled to the positioned insert-type main section. After welding, release the wire rope of the insert-type main section to be assembled to complete the positioning of the insert-type main section.

[0014] In some embodiments of this application, in step S5, after the positioning and welding of the pre-positioned insert-type section is completed, insert-type sections to be assembled can be set on both sides of the pre-positioned insert-type section along the deck side, so as to carry out the parallel installation of multiple insert-type sections to be assembled.

[0015] In some embodiments of this application, the protruding structure in step S2 includes a longitudinal truss located on the side of the insert section.

[0016] In some embodiments of this application, the protruding structure in step S2 includes a transverse rib located on the side of the insert section.

[0017] In some embodiments of this application, when hoisting the insertable section, the length of the insertable section is denoted as L1, the height of the insertable section as H1, the displacement of the insertable section along the length of the hull as L2, and the displacement of the insertable section along the height of the hull as H2. The margin confirmation in step S5 satisfies the following formula:

[0018]

[0019] In some embodiments of this application, the width of the insert section is denoted as B1, and the displacement of the insert section along the width of the hull is denoted as B2. The margin confirmation in step S5 can also satisfy the following formula:

[0020]

[0021] This invention provides a method for mounting an insert-type assembly, which has the following advantages compared to the prior art:

[0022] This application combines the hoisting status of the insert-type assembly with the structural dismantling status. During use, the insert-type assembly is hoisted and fixed first. At this time, the corresponding truss and rib plates in the corresponding area can be removed in advance according to the docking situation of the insert-type assembly, so as to avoid structural interference during the hoisting process, reduce the time for structural dismantling and reassembly, and save time. Furthermore, the operators can determine the displacement margin value after hoisting on-site based on the displacement formula of the insert-type assembly, saving the time for roughing positioning and measurement analysis, thereby achieving rapid installation.

[0032] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0033] It should be understood that the terms "before," "after," etc., are used in this invention to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, "before" information can also be called "after" information, and "after" information can also be called "before" information, without departing from the scope of this invention.

[0034] like Figures 1 to 8 As shown, this embodiment of the invention provides a method for mounting an insert-type assembly, which includes the following steps:

[0035] S1. Confirm the hoisting status of the insert-type main section to be assembled;

[0036] S2. Remove the protruding structure at the end of the insert-type main section to be assembled;

[0037] S3. Hoist the insertion section and adjust the length of the wire rope of the insertion section to achieve the hoisting state described in step S1.

[0038] S4. The insert-type main section is erected on the submerged body section and connected to the submerged body section;

[0039] S5. Align the insert-type section along the side of the deck, and insert the protruding structure of the insert-type section to be assembled into the positioned insert-type section to complete the connection between the insert-type section to be assembled and the positioned insert-type section.

[0040] S6. Measure the condition of the insert-type assembly section to be assembled, confirm the margin and cut it;

[0041] S7. Align several insertable sections along the sides of the deck with the width of the deck, and repeat steps S5 and S6.

[0042] S8. Position and adjust the insert-type main section to be assembled, and then weld the insert-type main section to be assembled to the positioned insert-type main section. After welding, release the wire rope of the insert-type main section to be assembled to complete the positioning of the insert-type main section.

[0043] like Figures 4 to 7 As shown, the extended structure in step S2 of this application includes a vertical truss 3 located at the bottom of the insert-type main section, a longitudinal truss 4 located on the side of the insert-type main section, and a transverse rib 5.

[0044] Furthermore, since the inserted section 1 has high inherent strength after fabrication, it can be assumed that it will not undergo hoisting deformation, meaning the overall shape of the inserted section 1 will not change. Therefore, the principle of a constant length-width-height ratio can be used to calculate the impact of any one of the length, width, or height components on the other two components. Specifically, during hoisting, let the length of the inserted section 1 be L1, the width be B1, the height be H1, the displacement along the hull length be L2, the displacement along the hull width be B2, and the displacement along the hull height be H2. Then, the displacements of the remaining inserted section 1 in step S6 satisfy the following formula:

[0045] or

[0046] Based on the above formula, the operator can calculate the displacement margin of the insert-type main section 1 during the hoisting operation according to the hoisting situation on site, so as to facilitate the operator to select countermeasures in a timely manner to ensure the normal splicing of the insert-type main sections 1.

[0047] In addition, such as Figure 8As shown, for step S4 of this application, after the positioning and welding of the pre-positioned insert-type section 200 is completed, insert-type sections 100 to be assembled can be simultaneously set on both sides of the pre-positioned insert-type section along the deck side, allowing for the parallel installation of multiple insert-type sections 100 to be assembled. Of course, the parallel installation of insert-type sections 100 to be assembled on the other side can only be carried out after the positioning and welding of insert-type sections 100 on one side is completed.

[0048] In summary, the present invention provides a method for mounting an insert-type assembly section, comprising the following steps: S1, confirming the hoisting state of the insert-type assembly section to be assembled; S2, removing part of the protruding structure at the end of the insert-type assembly section to be assembled; S3, hoisting the insert-type assembly section and adjusting the length of the steel wire rope used for hoisting the insert-type assembly section to achieve the hoisting state described in step S1; S4, placing the insert-type assembly section on the submersible section and connecting it to the submersible section; S5, aligning the insert-type assembly section along the deck side and removing the protruding structure of the insert-type assembly section to be assembled. S6. Insert the pre-positioned insert-type section to complete the connection between the insert-type section to be assembled and the pre-positioned insert-type section; S7. Measure the state of the insert-type section to be assembled, confirm the margin, and cut; S8. Align several insert-type sections set along the deck side along the width direction of the deck, and repeat steps S5 and S6; S9. Position and adjust the insert-type section to be assembled, and then weld the insert-type section to be assembled to the pre-positioned insert-type section. After welding, release the wire rope of the insert-type section to be assembled, completing the positioning of the insert-type section. Compared with the existing technology, this mounting method can confirm the position of the insert-type section to be dismantled in advance, reduce dismantling and reassembly time, and save time; operators can judge the displacement margin value after hoisting on-site according to the displacement formula of the insert-type section, saving the time for roughing positioning and measurement analysis, thereby achieving rapid mounting.

[0049] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
