[0002] At present, the mainstream large independent cargo hold asphalt ships adopt a double-side and single-bottom cargo hold area. For such cargo holds, the mainstream shipyards divide the cargo holds into bottom segments, double-side and bilge segments, and upper deck segments during sectional division. Among them, the side and bilge segments are usually of an integral welding structure, and its assembly scheme is as follows: First, taking the inner shell plate of the hull as a form, rib frame, platform and related internal side structures are assembled on the inner shell plate, and after welding is completed, an inner bottom large group is formed; then, the side outer plate is separately processed on a gantry assembly line and then installed on the ship sectional jig; subsequently, the inner bottom large group is integrally hoisted and turned over to the inner side of the side outer plate, and finally the welding is completed.

[0048] Referring to Figure 1 , the large ship side and bilge structure provided by the present utility model includes a side shell large group 1, a bilge shell large group 2, and an inner shell plate frame 3, wherein:

[0049] The side shell large group 1 includes a side rib plate frame 11 and a flat outer plate 12 fixed to the outside of the side rib plate frame 11;

[0050] The bilge shell large group 2 includes a bilge rib plate frame 21, a bilge turning plate 22 fixed to the outside of the bilge rib plate frame 21, and an internal flat plate 23 fixed above the bilge rib plate frame 21;

[0051] The inner shell plate frame 3 is buckled to the inside of the side rib plate frame 11 and the inside of the bilge rib plate frame 21.

[0052] It should be noted that the inside of the side rib plate frame 11 refers to the side close to the cabin of the side rib plate frame 11, and the outside of the side rib plate frame 11 refers to the side far from the cabin of the side rib plate frame 11. Similarly, the inside of the bilge rib plate frame 21 refers to the side close to the cabin of the bilge rib plate frame 21, and the outside of the bilge rib plate frame 21 refers to the side far from the cabin of the bilge rib plate frame 21.

[0053] The side and bilge structure of a large ship provided by the present utility model comprises three components, namely the large side shell group 1, the large bilge shell group 2, and the inner shell plate frame 3. The above three components are assembled independently, and after the independent assembly is completed, the overall assembly is completed on the sectional jig of the ship.

[0054] The specific assembly process is as follows:

[0055] First, assemble the large side shell group 1, the large bilge shell group 2, and the inner shell plate frame 3 respectively. Among them: the assembly scheme of the large side shell group 1 is to use the flat outer plate 12 as a jig, and install the side rib frame 11 on the flat outer plate 12 to form the large side shell group 1; the assembly scheme of the large bilge shell group 2 is to use the internal flat plate 23 as a jig, and install the bilge rib frame 21 and the scattered bilge turning plate 22 on the internal flat plate 23 to form the large bilge shell group 2; the inner shell plate frame 3 is assembled by passing through the panel assembly line.

[0056] Next, hoist the large side shell group 1 and the large bilge shell group 2 onto the sectional jig to complete the assembly. Or, the large side shell group 1 and the large bilge shell group 2 can be directly assembled on the sectional jig. The large side shell group 1 and the large bilge shell group 2 together form the outer shell group.

[0057] Subsequently, turn over and hoist the inner shell plate frame 3 and buckle it to the inside of the outer shell group, and finally complete the overall welding.

[0058] Different from the prior art, the side and bilge structure of a large ship provided by the present utility model is divided into three components. During the assembly process, first complete the assembly of the large side shell group 1 and the large bilge shell group 2 on the sectional jig, and then turn over and hoist the inner shell plate frame 3 and buckle it to the inside of the large side shell group 1 and the large bilge shell group 2. Since the weight of the inner shell plate frame 3 is relatively light, far less than 60t, the above structure can facilitate the adjustment of the position of the inner shell plate frame 3, improve the assembly accuracy of the side and bilge structure of a large ship, and reduce the assembly time at the same time.

[0059] In addition, for the case where the large side shell group 1 and the large bilge shell group 2 are directly assembled on the sectional jig, the overall section does not need to occupy a large lifting crane for the large group to turn over. Each section saves one estimated 60T crane for the large group to turn over operation, saving labor and crane occupancy time.

[0060] Continue to refer to Figure 1 , the inner shell plate frame 3 can adopt a multi-segment splicing structure to further reduce the weight of a single hoisting, thereby further reducing the difficulty of assembly.

[0061] Refer to Figure 2 and Figure 3, the side rib frame 11 includes several side limiting ribs 111 distributed in an array, several side longitudinal ribs 112 distributed in sequence along the horizontal direction, and several side transverse ribs 113 distributed in an array. The side limiting ribs 111, side longitudinal ribs 112, and side transverse ribs 113 are staggered with each other. Among them, the outer side of the side longitudinal rib 112 is fixed to the flat outer plate 12, and its inner side is connected to the inner hull plate frame 3; the side transverse rib 113 is laid and fixed between two adjacent side longitudinal ribs 112; the side limiting rib 111 is arranged on the inner side of the side rib frame 11 and connected to the inner hull plate frame 3.

[0062] Refer to Figure 4 , the bilge rib frame 21 includes several bilge limiting ribs 211 distributed in an array, several bilge longitudinal ribs 212 distributed in sequence along the horizontal direction, and several bilge transverse ribs 213 distributed in an array. The bilge limiting ribs 211, bilge longitudinal ribs 212, and bilge transverse ribs 213 are staggered with each other. The structure of the bilge rib frame 21 is similar to that of the side rib frame 11 and will not be repeated here.

[0063] Refer to Figures 5 to 9 , the inner hull plate frame 3 includes a flat inner plate 31, several first limit members 32 fixed on the flat inner plate 31, and several second limit members 33 fixed on the flat inner plate 31;

[0064] Several first limit grooves 1111 corresponding to the first limit members 32 one by one and engaged with them are provided on the inner side of the side rib frame 11;

[0065] Several second limit grooves 2111 corresponding to the second limit members 33 one by one and engaged with them are provided on the inner side of the bilge rib frame 21.

[0066] Specifically, several first limit grooves 1111 are provided on each side limiting rib 111; several second limit grooves 2111 are provided on each bilge limiting rib 211; the first limit members 32 and the second limit members 33 are distributed in an array on the flat inner plate 31. Among them, the first limit members 32 are located at the upper part of the flat inner plate 31, and the second limit members 33 are located at the lower part of the flat inner plate 31. Through the engagement of the limit members and the limit grooves, the position of the inner hull plate frame 3 relative to the outer hull assembly can be restricted, thereby improving the overall assembly accuracy.

[0067] In this embodiment, the mouths of the first limit grooves 1111 and the mouths of the second limit grooves 2111 are both in a flared shape, so that the limit members can smoothly fall into the limit grooves along the inclined surfaces of the mouths.

[0068] Refer to Figure 6, the first limiting member 32 has a fixed end and a free end which are oppositely arranged. The fixed end of the first limiting member 32 is fixed on the flat inner plate 31, and a first hook 321 is arranged at the free end of the first limiting member 32. The first hook 321 is hooked on the side limiting rib plate 111;

[0069] The second limiting member 33 has a fixed end and a free end which are oppositely arranged. The fixed end of the second limiting member 33 is fixed on the flat inner plate 31, and a second hook is arranged at the free end of the second limiting member 33. The second hook is hooked on the bilge limiting rib plate 211.

[0070] Further referring to Figure 10 , a first guiding inclined surface 3211 facing the flat inner plate 31 is arranged on the first hook 321. The first guiding inclined surface 3211 is inclined upward from the free end to the fixed end of the first hook 321;

[0071] A second guiding inclined surface facing the flat inner plate 31 is arranged on the second hook. The second guiding inclined surface is inclined upward from the free end to the fixed end of the second hook.

[0072] With the above structure, during the falling process of the inner hull plate frame 3, the guiding inclined surface can guide the inner hull plate frame 3 so that the hook can be smoothly hooked on the limiting rib plate.

[0073] Continuing to refer to Figure 6 , the inner hull plate frame 3 further includes a plurality of inner hull transverse rib plates 34 fixed on the flat inner plate 31. A inner hull transverse rib plate 34 is connected between any two adjacent first limiting members 32 in the horizontal direction and between any two adjacent second limiting members 33 in the horizontal direction.

[0074] On the basis of the above structure, continuing to refer to Figures 7 to 9 , a plurality of first slots 1121 are arranged on each side longitudinal rib plate 112 in sequence along the vertical direction;

[0075] A plurality of second slots 2121 are arranged on each bilge longitudinal rib plate 212 in sequence along the vertical direction;

[0076] The inner hull transverse rib plates 34 located above the flat inner plate 31 are inserted into the first slots 1121, and the inner hull transverse rib plates 34 located below the flat inner plate 31 are inserted into the second slots 2121.

[0077] The arrangement of the first slots 1121 and the second slots 2121 further improves the relative position accuracy between the outer hull assembly and the inner hull plate frame 3, thereby further improving the assembly accuracy.

[0078] Continuing to refer to Figure 10, as an optional embodiment, among a column of first limiting members 32 and second limiting members 33 distributed vertically, longitudinal rib plates are connected between any two adjacent members, and a column of first limiting members 32, second limiting members 33 and longitudinal rib plates distributed vertically can be integrally formed during blanking.

[0079] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
