[0002] In the field of shipbuilding, for the production of the hull, the hull needs to be split into multiple annular monomers along the bow and stern directions for processing and manufacturing, and then the multiple annular monomers are welded together to form the hull. The hull production method can complete the synchronous assembly and welding of multiple annular monomers in parallel in space and synchronously in time, which can greatly improve the production efficiency of the hull and shorten the slipway cycle.

[0048] Embodiment 1

[0049] In the field of shipbuilding, for the production of the hull, it is necessary to split the hull into multiple annular monomers along the bow and stern directions for processing and manufacturing, and then the multiple annular monomers are closed and welded together to form the hull. The hull production method can complete the synchronous assembly and welding of multiple annular monomers in parallel in space and synchronously in time, which can greatly improve the production efficiency of the hull and shorten the slipway cycle. However, the welding and fixation between the annular monomers will cause the welded monomers to shift relative to the predetermined position, resulting in the production quality of the hull after construction failing to meet production requirements. Moreover, since the annular monomers are very easy to deform during the assembly, welding, manufacturing and transportation process, the closing positioning accuracy between the annular monomers is low, which further affects the subsequent production quality of the hull.

[0050] In order to solve the above problem, this embodiment provides a ring-shaped monomer closing compensation method. The ring-shaped monomer closing compensation method includes the following steps:

[0051] S1. Producing and manufacturing the annular monomers arranged in sequence along the bow and stern directions according to preset processing parameters;

[0052] S2, building a folding platform, and dividing different areas in sequence along the bow and stern directions on the folding platform, each area corresponding to an annular monomer;

[0053] S3, taking an annular monomer located in the center along the bow and stern direction among the multiple annular monomers as a reference annular monomer, and clamping and fixing the reference annular monomer on a corresponding area on the closing platform;

[0054] S4, for each annular monomer except the reference annular monomer, a compensation offset is calculated according to the actual position of the rib line, the center line and the horizontal line relative to the reference annular monomer and the theoretical offset, and each annular monomer is clamped and fixed in the corresponding area of ​​the folding platform according to the compensation offset;

[0055] S5. The annular monomers other than the reference annular monomer are closed, docked and fixed together from both ends of the reference annular monomer along the bow and stern directions.

[0056] The annular monomer closing compensation method is to split the hull into a plurality of annular monomers connected in sequence along the bow and stern directions, process each annular monomer separately, and divide a plurality of areas in sequence along the bow and stern directions on the closing platform, so that each area corresponds to an annular monomer, and take an annular monomer located in the center along the bow and stern directions as a reference annular monomer, calculate the compensation offset according to the positions of the rib lines, center lines and horizontal lines in the remaining annular monomers relative to the base annular monomer and the theoretical offset, fix each annular monomer except the reference annular monomer in the corresponding area according to its own compensation offset, close and fix each annular monomer from both ends of the reference annular monomer along the bow and stern directions, realize the assembly and forming of the hull, and use the compensation offset to ensure that each annular monomer fixed together is arranged according to the theoretical position, ensure that the hull meets the production requirements, and improve the production quality of the hull.

[0057] Specifically, if Figure 1 and Figure 2 As shown, the hull provided in this embodiment includes a second annular monomer 200, a first annular monomer 100, a third annular monomer 300 and a fourth annular monomer 400 which are sequentially connected along the bow and stern directions. In the actual closing process, the first annular monomer 100 is used as the reference annular monomer, and the second annular monomer 200 and the third annular monomer 300 are closed with the first annular monomer 100 along the bow and stern directions respectively, and then the fourth annular monomer 400 is docked with the third annular monomer 300 along the bow and stern directions.

[0058] In actual operation, when the second annular monomer 200, the first annular monomer 100, the third annular monomer 300 and the fourth annular monomer 400 are closed and fixed together along the bow and stern direction to form the hull, the two ends of the hull along the bow and stern direction will be tilted upward. In order to compensate for the tilting of the two ends of the hull, the compensation offset A1 of the end of the second annular monomer 200 close to the first annular monomer 100 along the bow and stern direction is zero. The compensation offset A2 of the end of the third annular monomer 300 close to the first annular monomer 100 along the bow and stern direction is zero.

[0059] The compensation offset A3 of the second annular monomer 200 away from one end of the first annular monomer 100 along the bow and stern direction is calculated based on the position offset data of the actual rib line, center line and horizontal line of the second annular monomer 200 relative to the first annular monomer 100 and the theoretical compensation offset of the second annular monomer 200 away from one end of the first annular monomer 100 along the bow and stern direction.

[0060] The compensation offset A4 of the third annular monomer 300 away from one end of the first annular monomer 100 along the bow and stern direction is calculated based on the position offset data of the actual rib line, center line and horizontal line of the third annular monomer 300 relative to the first annular monomer 100 and the theoretical compensation offset of the third annular monomer 300 away from one end of the first annular monomer 100 along the bow and stern direction.

[0061] The compensation offset of the fourth annular monomer 400 along the bow and stern direction close to the end of the third annular monomer 300 is A4. The compensation offset A5 of the fourth annular monomer 400 along the bow and stern direction away from the end of the third annular monomer 300 is calculated based on the actual position offset data of the rib line, center line and horizontal line of the fourth annular monomer 400 relative to the first annular monomer 100 and the theoretical compensation offset of the fourth annular monomer 400 along the bow and stern direction away from the end of the first annular monomer 100.

[0062] In this embodiment, after the production of the first annular monomer 100 , the second annular monomer 200 , the third annular monomer 300 and the fourth annular monomer 400 is completed, the production quality of the first annular monomer 100 , the second annular monomer 200 , the third annular monomer 300 and the fourth annular monomer 400 is inspected.

[0063] It should be noted that, in this embodiment, the production quality inspection includes processing error inspection and structural strength inspection. The processing error inspection needs to detect whether the first annular monomer 100, the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400 are respectively processed according to the process requirements of the installation drawings, and whether the rib lines, center lines and horizontal lines in the first annular monomer 100, the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400 are clearly marked and the offset of the rib lines, center lines and horizontal lines relative to the theoretical rib lines, center lines and horizontal lines, so as to obtain the position offset data of the actual rib lines, center lines and horizontal lines in the second annular monomer 200, the third annular monomer 300 and the third annular monomer 300 relative to the first annular monomer 100. The structural strength inspection requires the flaw detection of the hanging horse on the first annular monomer 100, the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400, so that the hanging horse actually meets the welding requirements.

[0064] In one optional solution, in order to divide the various areas on the closing platform, it is necessary to first clean up the debris on the closing platform, and then install a marking plate at the center line of the slipway. Use a laser theodolite to mark the center line of the slipway and the area division lines of each annular monomer on the marking plate and mark them with foreign punches, then mark them with paint, and then submit them for inspection. Finally, prepare the piers, beams, door frames, sleepers and other items required for closing according to the process requirements.

[0065] In addition, when overlapping and closing the platform, it is necessary to prepare additional calibration poles and draw the hull baseline inside the calibration poles. By preparing additional calibration poles and marking the hull baseline on the calibration poles, when the various annular monomers are closed to form the hull, the baseline on the assembled hull can be compared and checked with the hull baseline on the calibration poles to verify whether the hull assembly is qualified. It should be noted that in this embodiment, the hull baseline includes the hull baseline, the hull waterline, and the deck line. In other embodiments, other baselines may be added to the hull baseline, which is not specifically limited in this embodiment. In addition, the calibration pole should be made of dry wood to prevent the calibration pole from deforming and ensure the calibration accuracy of the calibration pole.

[0066] In this embodiment, when it is necessary to clamp and fix the first annular monomer 100 as the reference annular monomer on the closing platform, the plumb bob method is used to adjust the center line of the first annular monomer 100 so that the center of the first annular monomer 100 coincides with the center line of the closing platform; the horizontal line of the first annular monomer 100 is adjusted using a level tube so that the horizontal line of the first annular monomer 100 is horizontal; the height of the first annular monomer 100 from the ground is determined according to the pier diagram, and the pier wood on the closing platform is compacted.

[0067] In addition, when marking the hull reference line on the calibration pole, the first annular monomer 100 serving as the reference annular monomer can be clamped and fixed on the folding platform, and the hull reference line can be marked based on the rib line, center line and horizontal line on the first annular monomer 100.

[0068] In this embodiment, after the first annular monomer 100 is clamped and fixed on the closing platform, according to the actual data of the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400, the theoretical rib lines corresponding to the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400 on the closing platform are engraved on the closing platform with the first annular monomer 100 as a reference, so as to verify the closing accuracy when the first annular monomer 100, the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400 are closed together.

[0069] Specifically, when the first annular monomer 100, the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400 are closed together, check whether the rib lines on the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400 are aligned with the theoretical rib lines on the closing platform. If so, the first annular monomer 100, the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400 are fixedly connected; if not, the positions of the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400 are adjusted until the rib lines of the first annular monomer 100, the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400 are aligned with the theoretical rib lines on the closing platform.

[0070] As an optional solution, the first annular monomer 100 , the second annular monomer 200 , the third annular monomer 300 and the fourth annular monomer 400 are welded and fixed together according to a preset welding sequence.

[0071] Taking the first annular monomer 100 as an example, Figure 3 The preset welding sequence is described. The first annular monomer 100 includes a lower outer bulkhead 110, two side outer bulkheads 120 respectively connected to the lower outer bulkhead 110, an upper outer bulkhead 130 connected to the two side outer bulkheads 120, a lower inner bulkhead 140, a side inner bulkhead 150, a first reinforcing beam 160 between the lower inner bulkhead 140 and the lower outer bulkhead 110, and a second reinforcing beam 170 between the side inner bulkhead 150 and the side outer bulkhead 120; the preset welding sequence is to weld the lower outer bulkhead 110, the side outer bulkhead 120, the lower inner bulkhead 140, the side inner bulkhead 150, the upper outer bulkhead 130, the first reinforcing beam 160, and the second reinforcing beam 170 in sequence. It should be noted that in this embodiment, the annular monomers need to be welded while being assembled to reduce the deformation of the closing welding. Specifically, after the second annular monomer 200 and the first annular monomer 100 are closed, the second annular monomer 200 and the first annular monomer 100 are welded and fixed, and then the third annular monomer 300 and the first annular monomer 100 are closed, and then the third annular monomer 300 and the first annular monomer 100 are welded and fixed, and finally the fourth annular monomer 400 and the third annular monomer 300 are closed and welded and fixed. It should be noted that the specific structure and welding sequence of the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400 are the same as the specific structure and welding sequence of the first annular monomer 100, and the specific structure and welding sequence of the second annular monomer 200, the third annular monomer 300 and the fourth annular monomer 400 will not be repeated here.

[0072] In addition, the annular monomers provided in this embodiment are all symmetrical along the center line in the vertical direction. During welding, two groups of workers can be arranged to weld symmetrically from both sides of the annular monomer to improve welding efficiency. The welding parameters referenced during the welding process are all welding parameters specified for hull welding in the prior art, and will not be described in detail here.

[0073] In order to ensure the welding effect between the annular monomers, the area to be welded of the annular monomers is cleaned before the annular monomers are welded and fixed. By cleaning the welding area before welding, the debris and dust in the welding area are effectively removed to achieve the purpose of improving the welding effect.
