Description

Technical Field

[0001] The present invention relates to the field of shipbuilding, and in particular to a saddle construction method, a saddle, a saddle assembly method, a ship construction method, and a ship. Background Art

[0002] Because ship saddles of previously constructed types were separated into three components, left, center, and right, each hoisted to the dock for welding, or assembled on a platform and then hoisted to the dock for welding, this method was inefficient and occupied multiple sites. The only advantage of split production was that it reduced the difficulty of precision, but for companies producing large quantities, it was very inefficient. Furthermore, in the past, ship saddles were divided into three assemblies. After the components were manufactured, they were assembled on the platform and then hoisted to the dock. During the hoisting process, the saddle opening became 20-30mm smaller, resulting in the need for surgical correction after docking, which was inefficient. Summary of the Invention

[0069] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0070] A saddle construction method comprises the following steps:

[0071] S10: Figure 1, draw an auxiliary line corresponding to the contour of the saddle on the ground, the auxiliary line at least including the upper height line 230 corresponding to the upper surface of the saddle and the arc 250 corresponding to the saddle opening 130, the auxiliary line includes a welding compensation allowance, wherein the compensation allowance specifically includes a lateral extension allowance corresponding to the welding of the ribs 120, the lateral extension allowance is 5mm longer for each rib 120, and the compensation allowance for the shrinkage of the opening 130 due to welding is to make the radius of the opening 130 5mm larger than the actual radius;

[0072] S20 : ​​aligning the assembled saddle assemblies 110 with the contour auxiliary line, and welding the assembled saddle assemblies 110 to form the saddle body 100 .

[0073] By adopting auxiliary line calibration, the overall construction of the saddle can be achieved, which saves construction time and makes the operation simpler.

[0074] In this embodiment, the specific steps of drawing the contour auxiliary line include:

[0075] S11: Draw a first horizontal auxiliary line 210 and a center line 220 of the first horizontal auxiliary line 210 , where the center line 220 is the center line 220 of the first horizontal auxiliary line 210 ;

[0076] S12: Draw an upper opening height line 230 and a lower opening height line 240 parallel to the first horizontal auxiliary line 210. A first preset distance is defined between the upper opening height line 230 and the lower opening height line 240, which is the horizontal height of the saddle. A second preset distance is defined between the upper opening height line 230 and the first horizontal auxiliary line 210, which is the difference between the radius of the opening 130 and the horizontal height of the saddle.

[0077] S13: Draw an arc 250 with the intersection of the first horizontal auxiliary line 210 and the center line 220 as the center, intersecting the upper height line 230;

[0078] S14 : According to the intersection point of the arc 250 and the upper opening height line 230 , two upper opening width lines 260 intersecting with the upper opening height lines 230 located on both sides of the arc 250 are determined.

[0079] The outer contour line of the saddle can be obtained by the above method, and the saddle can be aligned with the outer contour line and then the saddle can be spliced.

[0080] In this embodiment, step S20 specifically includes tack welding the assembled saddle body 100. The specific process of tack welding is as follows: the three separate components of the saddle are assembled and placed according to the outer contour of the saddle. The part alignment lines 111 on the different separate components are aligned, and the liquid seam center lines 220 and 112 on the separate components are aligned with the center line 220. At this point, the assembled saddle is determined to be in the correct position. The assembled saddle is then tack welded to obtain the saddle body 100.

[0081] Combine Figure 2 In this embodiment, it is more preferable to provide a margin portion 113 for welding shrinkage on both sides of the saddle body 100, and the margin portion 113 gradually extends outward from the bottom to the top. The top width of the margin portion 113 is 8 mm.

[0082] In this embodiment, after step S20, the following steps are further included:

[0083] S30: Combined Figure 1 and Figure 3 On the ground, multiple rib auxiliary lines 270 are drawn, starting from the center of the arc 250 and extending in the direction of the arc 250. The contour auxiliary lines and the rib auxiliary lines 270 are then mapped onto the assembled saddle assembly 110. This facilitates subsequent welding of the ribs 120 and allows for easy detection and calibration of the deformation of the ribs 120 during welding based on the rib auxiliary lines 270.

[0084] The assembled saddle assembly 110 is welded. Selecting to weld after drawing the rib auxiliary line 270 can facilitate understanding and controlling the deformation allowance of the saddle.

[0085] In this embodiment, after step S30, the following steps are further included:

[0086] Step S40: panel welding is performed on the saddle body 100 .

[0087] The step S40 specifically includes:

[0088] S41: Combine Figure 4 , manufacturing a tire frame 600 corresponding to the saddle body 100, and vertically placing the saddle body 100 on the tire frame 600, when the saddle body 100 is placed on the tire frame 600, the upper surface of the saddle body 100 can be horizontal;

[0089] S42: Panel welding is performed on the vertically placed saddle body 100.

[0090] During panel welding on the opposite saddle body 100 , the deformation degree of the saddle body 100 can be controlled according to the spacing between the panel openings 130 at different heights.

[0091] Combine Figure 5 In this embodiment, after step S40, the following steps are further included:

[0092] S50 : Install ribs 120 on both sides of the saddle body 100 .

[0093] The step S50 specifically includes:

[0094] S51: Welding a reinforcement bracket 300 in the opening 130 of the saddle body 100. The reinforcement bracket 300 can reduce welding shrinkage of the saddle. The reinforcement bracket 300 includes a crossbeam spanning the opening 130 and a plurality of vertical beams connecting the crossbeam. The crossbeam should be made of at least 30H steel, and the vertical beams can be made of 25 I-beams.

[0095] S52: Place the saddle in a lying position;

[0096] S53: Welding a rib 120 on one side surface of the saddle;

[0097] S54: Flip saddle;

[0098] S55: Welding rib 120 on the other side surface of the saddle;

[0099] The ribs 120 on the surface of the saddle body 100 are welded using a skip welding method, from both sides to the center. Skip welding involves welding one rib 120, then skipping the adjacent rib 120 and welding the next rib 120. Skip welding can reduce concentrated heat shrinkage and minimize welding deformation.

[0100] In this embodiment, step S50 further includes:

[0101] S56: Annealing the saddle to reduce the residual stress after removing the reinforcing bracket 300 , which causes the opening 130 to become smaller.

[0102] Combine Figure 5 and Figure 6 In this embodiment, after S50, the following steps are further included:

[0103] S60: Install the baffle 400 on the surface of the arc 250-shaped opening 130 of the saddle.

[0104] Combine Figure 6 In this embodiment, after S60, the following steps are also included:

[0105] S70 : Install the jump stoppers 500 on the upper surfaces of both sides of the saddle opening 130 .

[0106] The present invention also provides a saddle manufactured by the saddle manufacturing method as described above.

[0107] The present invention also provides a saddle assembly method, which is applicable to the saddle as described above, and the saddle assembly method comprises the following steps:

[0108] The saddle as described above is welded to the hull. The welding steps are as follows: firstly, the saddle body 100 is welded to the hull, and then the ribs 120 of the saddle are welded to the hull.

[0109] The present invention also provides a shipbuilding method, including the saddle assembly method as described above.

[0110] The present invention also provides a ship, which is built using the ship building method as described above.
