Description

Technical Field

[0001] The present application relates to the technical field of shipbuilding, and in particular to a ship segment closing mouth structure. Background Art

[0002] Block manufacturing is a crucial component of modern shipbuilding, and its technological advancements have significantly improved the efficiency and precision of shipbuilding. By breaking down the entire hull into multiple sections for separate manufacturing and subsequent assembly, this not only fully utilizes shipbuilding site resources but also enables modular production, improving productivity. This technology significantly reduces shipbuilding costs and shortens construction cycles, while also improving the consistency and reliability of ship quality, playing a key role in advancing the modernization of the shipbuilding industry.

[0003] During the ship segment closing process, to ensure precise alignment between segments, various measures are typically required to maintain the shape stability of the closing joint. A common solution in the prior art involves using a pre-set tensioning device to pull the edges of the closing joint to a predetermined position, thereby achieving shape stability.

[0004] When the closing mouth is deformed, the deformation degree of each position of the closing mouth is different, which requires adjusting the force direction and force magnitude of the tensioning device at each position of the closing mouth, and the workload required for adjustment is large. Summary of the Invention

[0005] In order to keep the closing mouth to be closed in a preset shape, the present application provides a ship segmented closing mouth structure.

[0006] The present application provides a ship segment closing structure adopting the following technical solutions: A ship segment closing structure includes ship segments and supporting ribs. The ship section has a mouth to be closed, The support ribs are connected to the inner side of the opening to be closed, and the support ribs have the same or similar curvature as the preset shape of the opening to be closed. The support ribs are used to keep the opening to be closed in the preset shape.

[0007] By adopting the above technical solution, support ribs are used to provide support for the closing mouth of the ship section, and the deformation of the closing mouth is controlled, so that the preset shape of the closing mouth can be effectively maintained, preventing deformation during manufacturing or transportation (of the ship section within the shipyard), thereby improving the stability and reliability of the ship section closing mouth structure.

[0008] Preferably, it also includes a pull rod, One end of the pull rod is used to be connected to the ship section, and the other end of the pull rod is used to be connected to the supporting rib. The pull rod is used to make the inner side surface of the opening to be closed fit against the supporting rib.

[0009] By adopting the above technical solution, when the opening to be closed is concave, the support ribs provide thrust for the concave portion of the opening to be closed, so that the concave portion of the opening to be closed moves outward to restore the preset shape.

[0010] When the opening to be closed is convex, the pull rod is used to provide tension to the concave portion of the opening to be closed, so that the concave portion of the opening to be closed moves inward to fit the support ribs to restore the preset shape.

[0011] Preferably, the pull rod includes a connecting sleeve, a main connecting rod, a secondary connecting rod and two abutment blocks. The connecting sleeve is connected between the main connecting rod and the auxiliary connecting rod. The two abutment blocks are respectively connected to the main connecting rod and the auxiliary connecting rod, and the opposite surfaces of the two abutment blocks are respectively used to abut against the supporting ribs and the outer side surfaces of the opening to be closed. The connecting sleeve is used to bring the two abutting blocks closer to each other.

[0012] By adopting the above technical solution, the connecting sleeve is used to drive the two abutting blocks closer to each other, so that the inner side surface of the opening to be closed is in contact with the supporting rib.

[0013] Preferably, the connecting sleeve is threadedly connected between the main connecting rod and the auxiliary connecting rod. The inner circumference of the connecting sleeve is provided with left-hand thread and right-hand thread. The cross section of the main connecting rod is a fan, fan ring or arcuate with a central angle A of not less than 180°. The cross section of the secondary connecting rod is a sector, sector ring or arcuate shape with a central angle B not greater than 180°, and the sum of the central angle B and the central angle A is not greater than 360°. The thread rotation direction of the main connecting rod and the thread rotation direction of the auxiliary connecting rod are opposite.

[0014] By adopting the above technical solution, the position of the connecting sleeve on the main connecting rod is adjusted according to the protrusion of the opening to be closed; that is, the greater the protrusion of the opening to be closed, the greater the distance between the abutment blocks of the adjusting connecting sleeve and the main connecting rod.

[0015] More specific: When the connecting sleeve is connected to the main connecting rod, the two abutment blocks are respectively abutted against the supporting ribs and the outer side of the opening to be closed, and the connecting sleeve is rotated so that the connecting sleeve avoids the secondary connecting rod, and the secondary connecting rod is attached to the main connecting rod, and the connecting sleeve is rotated again to drive the two abutment blocks closer to each other; When the connecting sleeve is connected to the secondary connecting rod, the two abutment blocks are respectively abutted against the supporting ribs and the outer side surfaces of the opening to be closed, and the connecting sleeve is directly moved so that the connecting sleeve avoids the main connecting rod, the main connecting rod is fitted to the secondary connecting rod, and then the connecting sleeve is moved until the connecting sleeve is close to the main connecting rod, and finally the connecting sleeve is rotated to drive the two abutment blocks close to each other.

[0016] Preferably, the central angle A is greater than 180°.

[0017] By adopting the above technical solution, when the connecting sleeve is connected to the main connecting rod, the connection between the connecting sleeve and the main connecting rod is stable; When the connecting sleeve is connected to the auxiliary connecting rod, it is convenient for the connecting sleeve and the auxiliary connecting rod to be disconnected from the threaded connection.

[0018] Preferably, the sum of the central angle B and the central angle A is equal to 360°.

[0019] By adopting the above technical solution, the cross-sections of the main connecting rod and the auxiliary connecting rod complement each other to form a complete circular structure, so the connecting sleeve can more stably connect the main connecting rod and the auxiliary connecting rod, thereby improving the reliability of the overall structure.

[0020] Preferably, at least one of the abutment blocks is provided with an embedding hole, and the embedding hole is used for embedding the main connecting rod or the auxiliary connecting rod.

[0021] By adopting the above technical solution, the reaction force of the ship section and the supporting ribs on the abutment block causes the inner side surface of the embedded hole and the main connecting rod (or auxiliary connecting rod) to squeeze each other, thereby increasing the friction between the abutment block and the main connecting rod (or auxiliary connecting rod), so that the main connecting rod (or auxiliary connecting rod) drives the abutment blocks closer to each other.

[0022] When the pull rod needs to be removed, the main connecting rod (or auxiliary connecting rod) drives the abutment blocks away from each other, and the mutual extrusion force between the inner side surface of the embedded hole and the main connecting rod (or auxiliary connecting rod) is reduced to 0, which can drive the abutment blocks and the main connecting rod (or auxiliary connecting rod) to move relative to each other to complete the removal of the pull rod.

[0023] Preferably, the pull rod further includes a wedge. The wedge block is used to be embedded in the embedding hole, and the small end of the wedge block faces the connecting sleeve.

[0024] By adopting the above technical solution, in the process of the main connecting rod (or auxiliary connecting rod) driving the abutment blocks to approach each other, the wedge block helps to increase the mutual extrusion force between the inner side surface of the embedded hole and the main connecting rod (or auxiliary connecting rod), so that the friction force can make the abutment block move with the main connecting rod (or auxiliary connecting rod) to correct the opening to be closed.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By coordinating the support ribs with the inner side of the opening to be closed and utilizing the curvature characteristics of the support ribs, the preset shape of the opening to be closed is effectively maintained, reducing the risk of deformation; 2. The setting of the tie rod further enhances the fit between the closing mouth and the supporting ribs, improving the overall stability of the structure; 3. The pull rod is designed as a combination of a connecting sleeve, a main connecting rod, a secondary connecting rod, and abutment blocks, ensuring a reliable connection between the outer side of the closing mouth and the supporting ribs. At the same time, the adjustment function of the connecting sleeve enables precise positioning and fixation. 4. The left-hand and right-hand thread design of the connecting sleeve, combined with the special cross-sectional shape of the main connecting rod and the auxiliary connecting rod, makes operation more convenient, the adjustment range is wider, and the adaptability is stronger; 5. The design of the embedded hole improves the connection strength between the pull rod and the abutment block to prevent loosening, and the small end of the wedge block faces the connecting sleeve, which further enhances the stability of the embedding and avoids displacement or falling off during the force process.

[0035] The present application is further described in detail below with reference to the accompanying drawings.

[0036] Reference Figure 1 and Figure 2 , an embodiment of the present application discloses a ship segment closing mouth structure, including a ship segment 1 and a supporting rib 2.

[0037] The ship section 1 has a mouth 11 to be closed, and the mouth 11 to be closed should have a preset shape determined by the designer.

[0038] The support ribs 2 are connected to the inner side of the opening 11 to be closed. The support ribs 2 have the same or similar curvature as the preset shape of the opening 11 to be closed. The support ribs 2 are used to maintain the preset shape of the opening 11 to be closed. In one embodiment, the support ribs 2 are connected to the inner side of the opening 11 to be closed by welding.

[0039] When the opening 11 to be closed is concave, the support ribs 2 can be directly attached to the inner side surface of the opening 11 to be closed. The support ribs 2 provide thrust for the concave portion of the opening 11 to be closed, so that the concave portion of the opening 11 to be closed moves outward to restore the preset shape.

[0040] Reference Figure 2 When the opening 11 to be closed is convex, a gap is formed between the inner side surface of the opening 11 to be closed and the supporting rib 2.

[0041] The ship segment closing structure also includes a tie rod 3. One end of the tie rod 3 is connected to the ship segment 1, and the other end is connected to the support rib 2. The tie rod 3 is used to make the inner side of the closing mouth 11 fit against the support rib 2 to correct the convexity of the closing mouth 11. The inner side of the closing mouth 11 is then fixed to the support rib 2 by welding, and the tie rod 3 can be removed afterwards.

[0042] The supporting rib 2 includes a supporting plate 21 and a bonding plate 22 .

[0043] The support plate 21 is a flat plate, and its edge has a curvature that is the same as or similar to the predetermined shape of the opening 11 to be closed. A bonding plate 22 is connected to the edge of the support plate 21 and is perpendicular to the support plate 21. The surface of the bonding plate 22 facing away from the support plate 21 is used to mate with the inner side of the opening 11 to be closed. The surface of the bonding plate 22 facing away from the support plate 21 is used to connect with the pull rod 3.

[0044] In one embodiment, the support rib 2 may be an I-beam.

[0045] Reference Figure 3 and Figure 4 The pull rod 3 includes a connecting sleeve 31 , a main connecting rod 32 , a secondary connecting rod 33 and two abutting blocks 34 .

[0046] The connecting sleeve 31 is connected between the main connecting rod 32 and the auxiliary connecting rod 33. Two abutment blocks 34 are respectively connected to the main connecting rod 32 and the auxiliary connecting rod 33. The opposite surfaces of the two abutment blocks 34 are used to abut against the outer side surface of the opening to be closed 11 and the laminating plate 22 respectively.

[0047] The connecting sleeve 31 is used to bring the two abutting blocks 34 closer to each other.

[0048] The connecting sleeve 31 is threadedly connected between the main connecting rod 32 and the auxiliary connecting rod 33. The inner circumference of the connecting sleeve 31 is provided with a left-hand thread and a right-hand thread.

[0049] The cross-section of the main connecting rod 32 is a sector, sector ring, or arcuate shape with a central angle A of no less than 180°. The cross-section of the secondary connecting rod 33 is a sector, sector ring, or arcuate shape with a central angle B of no more than 180°. The sum of the central angles B and A is no greater than 360°. The threads of the main connecting rod 32 and the secondary connecting rod 33 have opposite rotation directions and equal pitch.

[0050] In one embodiment, the central angle A is greater than 180°, and the sum of the central angle B and the central angle A is equal to 360°.

[0051] Reference Figure 5 and Figure 6 , according to the outward protrusion of the opening 11 to be closed, the position of the connecting sleeve 31 on the main connecting rod 32 is adjusted; that is, the greater the outward protrusion of the opening 11 to be closed, the greater the distance between the adjusting connecting sleeve 31 and the abutment block 34 connected to the main connecting rod 32.

[0052] When the connecting sleeve 31 is connected to the main connecting rod 32, the two abutment blocks 34 are respectively abutted against the outer sides of the support rib 2 and the opening to be closed 11, and the connecting sleeve 31 is rotated so that the connecting sleeve 31 avoids the secondary connecting rod 33, and the secondary connecting rod 33 is fitted to the main connecting rod 32, and then the connecting sleeve 31 is rotated to drive the two abutment blocks 34 to approach each other.

[0053] When the connecting sleeve 31 is connected to the secondary connecting rod 33, the two abutment blocks 34 are respectively abutted against the outer sides of the support rib 2 and the opening to be closed 11, and the connecting sleeve 31 is directly moved so that the connecting sleeve 31 avoids the main connecting rod 32, and the main connecting rod 32 is fitted to the secondary connecting rod 33, and then the connecting sleeve 31 is moved until the connecting sleeve 31 is close to the main connecting rod 32, and finally the connecting sleeve 31 is rotated to drive the two abutment blocks 34 to approach each other.

[0054] Reference Figure 7 At least one abutment block 34 is provided with an embedding hole 341, and the embedding hole 341 is used for the main connecting rod 32 or the auxiliary connecting rod 33 to be embedded.

[0055] The inner side surface of the embedding hole 341 and the main connecting rod 32 (or the auxiliary connecting rod 33 ) may be clearance-fitted to facilitate the abutment block 34 to be sleeved onto the main connecting rod 32 (or the auxiliary connecting rod 33 ).

[0056] Reference Figure 6 and Figure 7When the two abutment blocks 34 clamp the ship section 1 and the support rib 2, the reaction force F of the ship section 1 and the support rib 2 on the abutment block 34 applies a moment M on the abutment block 34. The moment M causes the inner side of the embedding hole 341 and the main connecting rod 32 (or the auxiliary connecting rod 33) to squeeze each other. Figure 7 increase the friction between the abutment block 34 and the main connecting rod 32 (or the auxiliary connecting rod 33), so that the main connecting rod 32 (or the auxiliary connecting rod 33) drives the abutment blocks 34 closer to each other through friction.

[0057] Reference Figure 8 In another embodiment, the pull rod 3 further includes a wedge 35 ; the wedge 35 is used to be embedded in the embedding hole 341 , with the small end of the wedge 35 facing the connecting sleeve 31 .

[0058] When the main connecting rod 32 (or the auxiliary connecting rod 33) drives the abutment blocks 34 to approach each other, the wedge block 35 helps to increase the mutual squeezing force between the inner surface of the embedding hole 341 and the main connecting rod 32 (or the auxiliary connecting rod 33), so that the friction force can make the abutment blocks 34 move with the main connecting rod 32 (or the auxiliary connecting rod 33) to correct the opening 11 to be closed.

[0059] The implementation principle of a segmented closing mouth structure of a ship in an embodiment of the present application is: by cooperating with the support ribs 2 and the inner surface of the opening to be closed 11, and utilizing the curvature characteristics of the support ribs 2, the preset shape of the opening to be closed 11 is effectively maintained to reduce the risk of deformation.

[0060] The coordination of support ribs 2 and tie rods 3 effectively addresses the difficulty traditional tensioning devices face in accurately adapting to complex curved surfaces. The design of support ribs 2 ensures the closure maintains its pre-set shape, while the adjustable structure of tie rods 3 further enhances the stability of the closure. This design not only improves the precision of the ship's section closure but also accommodates the needs of varying sizes and shapes, significantly enhancing the efficiency and quality of shipbuilding.

[0061] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
