Description

TECHNICAL FIELD

[0001] The application relates to a multi-island general assembly method of a superstructure of a ship. BACKGROUND

[0002] The superstructure of a ship needs to be built layer by layer due to a large number of layers of the superstructure. A traditional general assembly method of the superstructure is to perform general assembly of left and right side sections of one deck layer by layer on a general assembly jig, then hoist left and right side sections of another deck layer to the last layer of the general assembly to perform general assembly, and then perform general assembly of each deck layer in sequence, layer by layer. However, the general assembly method has the following defects. First, the general assembly method occupies the general assembly jig for a long period of time, which is not conducive to the general assembly of the superstructure of a subsequent ship. Second, the general assembly method of the superstructure is long, and cannot meet the production node plan of the company. Third, the amount of high-altitude operation is increased, and safety risks exist. SUMMARY

[0003] The application aims to overcome the defects of the prior art, such as a long general assembly period of the superstructure of a ship and a long time consumption, and provides a multi-island general assembly method of a superstructure of a ship.

[0004] The application solves the above technical problems by the following technical scheme.

[0005] The application provides a multi-island general assembly method of a superstructure of a ship, and the superstructure of the ship comprises a plurality of deck sections. The multi-island general assembly method comprises the following steps.

[0006] S1, performing general assembly of left and right side sections of a plurality of deck sections;

[0007] S2, loading the plurality of deck sections to form a plurality of general assembly sections;

[0008] S3, loading the plurality of general assembly sections.

[0009] In the application, the left and right side sections of the plurality of deck sections are reassembled first, then the plurality of deck sections are loaded to form the plurality of general assembly sections, and finally the plurality of general assembly sections are transported to a dock for loading. The defects caused by the method of performing general assembly of the left and right side sections of the lowermost deck section on a general assembly jig and then performing general assembly from the lowermost deck section to the uppermost deck section are overcome. The multi-island general assembly method has the following advantages. First, the multi-island general assembly method reduces the period of occupation of the general assembly jig by simultaneously performing general assembly of a plurality of sections, which is conducive to the general assembly of the superstructure of a subsequent ship. Second, the multi-island general assembly method improves efficiency, shortens the general assembly period of the superstructure, and meets the production node plan of the company. Third, the general assembly of each deck section is completed in advance, the long-term high-altitude operation caused by the layer-by-layer general assembly method is reduced, and safety risks are reduced.

[0010] Preferably, the deck section comprises a general assembly jig, and the step S1 specifically comprises the following steps.

[0011] The total assembly jig is placed on the total assembly site, and the first layer of deck segments is positioned and assembled on the total assembly jig to form the left and right side segments;

[0012] The left and right side segments of the remaining layers of deck segments are simultaneously assembled.

[0013] In this scheme, in step S1, the total assembly jig is installed on the total assembly site, and the positioning and assembly of the left and right side segments of the bottom layer of deck segments are completed, and the assembly of the left and right side segments of the other deck segments is simultaneously performed. Parallel operation of segments improves efficiency, reduces high-altitude operation time, and reduces safety risks.

[0014] Preferably, the weight of any layer of the total segment is less than the actual lifting capacity of the dock hoisting equipment.

[0015] In this scheme, the weight of any layer of the total segment is ensured to be less than the actual lifting capacity of the dock hoisting equipment, so that the actual operation requirements can be met when the total segment is finally loaded, and the actual weight of each layer of the total segment exceeding the upper limit of the lifting capacity of the dock hoisting equipment is avoided, which is dangerous.

[0016] Preferably, the actual lifting capacity of the dock hoisting equipment is greater than the preset lifting capacity, and the step S2 specifically comprises the following steps:

[0017] S21, a plurality of layers of the deck segments are grouped and spliced to form a plurality of layers of pre-total segments;

[0018] S22, the plurality of layers of pre-total segments are loaded to form the plurality of layers of total segments.

[0019] In this scheme, a preset value is set for the lifting capacity of the dock hoisting equipment. When the actual lifting capacity of the dock hoisting equipment is greater than the preset value, it indicates that the force that the dock hoisting equipment can withstand is larger, and then the method of S21 and S22 is adopted to form a plurality of layers of pre-total segments and then load the pre-total segments to form total segments, thereby improving the efficiency of installation and loading.

[0020] Preferably, the step S21 specifically comprises the following steps:

[0022] The fourth layer of deck segments, the fifth layer of deck segments, and the sixth layer of deck segments are assembled to form a second pre-total segment;

[0023] The seventh layer of deck segments, the steering layer of deck segments, and the compass layer of deck segments are assembled to form a third pre-total segment.

[0024] In the scheme, in addition to the first deck segment, the rest of the deck segments and the driving layer deck segment and the compass deck segment are respectively assembled to form the first pre-assembly, the second pre-assembly and the third pre-assembly, which provides a precondition for further installation of each layer assembly and improves the installation efficiency.

[0025] Preferably, the step S2 specifically comprises the following steps:

[0026] The first pre-assembly is hoisted to the first deck segment to form a first assembly;

[0027] The third pre-assembly is hoisted to the second pre-assembly to form a second assembly.

[0028] In the scheme, the pre-assembly of each layer is assembled according to the predetermined method to form the first assembly and the second assembly, which is fast and efficient, simple for the person skilled in the art and reduces the operation cost.

[0029] Preferably, the step S3 specifically comprises the following steps:

[0030] The first assembly and the second assembly are assembled.

[0031] In the scheme, the first assembly and the second assembly are finally assembled to complete the assembly of the superstructure of the ship and realize the rapid assembly of the superstructure of the ship.

[0032] Preferably, the lifting capacity of the dock hoisting equipment is less than the preset lifting capacity, and the step S2 specifically comprises the following steps:

[0033] The second deck segment, the third deck segment, the fourth deck segment, the fifth deck segment, the sixth deck segment, the seventh deck segment and the driving layer deck segment are respectively assembled to the left and right side segments.

[0034] In the scheme, a preset value is also set for the lifting capacity of the dock hoisting equipment. When the actual lifting capacity of the dock hoisting equipment is less than the preset value, it is shown that the dock hoisting equipment can bear less force, and the above steps are adopted. In addition to the first deck segment, the second deck segment, the third deck segment, the fourth deck segment, the fifth deck segment, the sixth deck segment, the seventh deck segment and the driving layer deck segment are respectively assembled to the left and right side segments, which are multiple steps in parallel and improve the efficiency of installation and assembly.

[0035] Preferably, the step S2 specifically comprises the following steps:

[0036] The second deck segment and the first deck segment are assembled to form a first assembly;

[0037] The third deck segment, the fourth deck segment and the fifth deck segment are assembled to form a second assembly;

[0038] The sixth deck segment, the seventh deck segment, the bridge deck segment and the compass deck segment are assembled to form a third assembly.

[0039] In the present application, the deck segments, the bridge deck segment and the compass deck segment are assembled according to a predetermined method to form a first assembly, a second assembly and a third assembly, which is fast and efficient, and simple for a person skilled in the art to operate, thereby reducing the operation cost

[0040] Preferably, the step S3 specifically comprises the following steps:

[0041] The first assembly, the second assembly and the third assembly are assembled.

[0042] In the present application, the first assembly, the second assembly and the third assembly are finally assembled to complete the assembly of the superstructure of the ship, thereby realizing the rapid assembly of the superstructure of the ship.

[0043] On the basis of the common sense in the art, the above-mentioned preferred conditions can be combined arbitrarily, thereby obtaining each preferred example of the present application.

[0044] The positive progress effect of the present application is that, in the present application, by using the above-mentioned multi-island assembly method, the left and right side segments of the multi-layer deck segments are reassembled first, then the multi-layer deck segments are assembled to form multi-layer assemblies, and finally the multi-layer assemblies are transported to the dock for assembly, thereby overcoming the defects caused by the method of assembling the left and right side segments of the lowermost deck segment from the assembly jig, and then sequentially assembling from bottom to top.

By adopting the above multi-island assembly method, the left and right side segments of the multi-deck segments are first reassembled, then the multi-deck segments are assembled to form multi-deck segments, and finally the multi-deck segments are transported to the dock for assembly. The defects caused by the method of assembling the left and right side segments of the lowermost deck segment from the assembly jig, and then sequentially assembling from bottom to top are overcome. The multi-island reassembly method has the following advantages: first, the multi-segment assembly method reduces the period of occupying the assembly jig, which is beneficial to the subsequent assembly of the ship superstructure; second, the multi-island assembly method improves the efficiency and shortens the assembly period of the superstructure, which meets the production node plan of the company; third, the assembly of each deck segment is completed in advance, which reduces the long-term overhead work caused by the layer assembly method and reduces the safety risk.

[0059] Specifically, each layer deck segment is formed into a corresponding deck section through the total assembly of the left and right side segments.

[0060] In the preferred embodiment, the total assembly cycle of the superstructure of the ship can be greatly shortened by the multi-island total assembly mode, labor cost is saved, the occupation cycle of the total assembly jig is reduced, thereby avoiding increasing the number of total assembly jigs and saving material cost, the frequency of high-altitude lifting is reduced, and the risk of high-altitude operation is reduced. In summary, the economic benefits, safety, quality and other aspects have been greatly improved.

[0061] Specifically, in the embodiment 1 of the present application, the first layer deck segment, the second layer deck segment, the third layer deck segment, the fourth layer deck segment, the fifth layer deck segment, the sixth layer deck segment, the seventh layer deck segment, the driving layer deck segment 11 and the compass deck segment 12 are included. In order to distinguish different deck segments and facilitate reference, in the embodiment, the first layer deck segment is named as A layer deck segment 1, the second layer deck segment is named as B layer deck segment 2, the third layer deck segment is named as C layer deck segment 3, the fourth layer deck segment is named as D layer deck segment 6, the fifth layer deck segment is named as E layer deck segment 7, the sixth layer deck segment is named as F layer deck segment 8, and the seventh layer deck segment is named as G layer deck segment 10.

[0062] The deck segment includes a total assembly jig, and step S1 specifically includes the following steps: placing the total assembly jig on the total assembly site, positioning and total assembling the left and right side segments of the first layer deck segment on the total assembly jig, and simultaneously total assembling the left and right side segments of the remaining layer deck segments. In step S1, the total assembly jig is installed on the total assembly site, the positioning and total assembly of the left and right side segments of the first layer deck segment are completed, and the total assembly of the left and right side segments of the other deck segments is simultaneously performed.

[0063] In a further preferred embodiment, the A layer deck segment 1 is used as the first layer deck segment, the positioning and total assembly of the left and right side segments of the A layer deck segment 1 are performed on the total assembly jig, and simultaneously the total assembly of the left and right side segments of the B layer deck segment 2, the C layer deck segment 3, the D layer deck segment 6, the E layer deck segment 7, the F layer deck segment 8, the G layer deck segment 10 and the driving layer deck segment 11 is performed. After total assembly, the A layer deck section, the B layer deck section, the C layer deck section, the D layer deck section, the E layer deck section, the F layer deck section, the G layer deck section and the driving layer deck section are formed.

[0064] It should be noted that the A deck segment, the B deck segment, the C deck segment, the D deck segment, the E deck segment, the F deck segment, the G deck segment and the driving deck segment are not the same concept as the first segment 5 and the second segment 14, and the first segment 5 and the second segment 14 are formed by the mounting of the A deck segment, the B deck segment, the C deck segment, the D deck segment, the E deck segment, the F deck segment, the G deck segment and the driving deck segment.

[0065] The weight of any one layer segment is less than the actual lifting capacity of the dock hoisting equipment.

A preset value is set for the lifting capacity of the dock hoisting equipment. When the actual lifting capacity of the dock hoisting equipment is greater than the preset value, it is shown that the force that the dock hoisting equipment can bear is larger, and then the method of S21 and S22 is adopted to form a multi-layer pre-segment and then mount the pre-segment to form a segment, so as to fully improve the efficiency of installation and mounting.

[0067] Specifically, in this embodiment 1, the preset lifting capacity is set to 600 tons, and the first pre-segment 4, the second pre-segment 9 and the third pre-segment 13 are included.

[0068] In the preferred embodiment, the B deck segment 2, the C deck segment 3 are simultaneously assembled to form the first pre-segment 4 on the assembly field beside the assembly jig, the D deck segment 6, the E deck segment 7, the F deck segment 8 are simultaneously assembled to form the second pre-segment 9, and the G deck segment 10, the driving deck segment 11 and the compass deck segment 12 are simultaneously assembled to form the third pre-segment 13.

[0069] The step S21 specifically comprises the following steps: assembling the second deck segment and the third deck segment to form the first pre-segment 4; assembling the fourth deck segment, the fifth deck segment and the sixth deck segment to form the second pre-segment 9; assembling the seventh deck segment, the driving deck segment 11 and the compass deck segment 12 to form the third pre-segment 13. Except for the first deck segment, the remaining deck segments and the driving deck segment 12 and the compass deck segment 12 are respectively assembled to finally form the first pre-segment 4, the second pre-segment 9 and the third pre-segment 13, which provides a precondition for further installation and mounting of each layer segment and improves the installation efficiency.

[0070] Step S2 specifically comprises the following steps: hoisting the first pre-block 4 to the first deck segment to form the first block 5; hoisting the third pre-block 13 to the second pre-block 9 to form the second block 14. The pre-blocks of each layer are carried according to the predetermined method to form the first block 5 and the second block 14, which is fast and efficient, and simple for the person skilled in the art to operate, thereby reducing the operation cost.

[0071] In the preferred embodiment, including the first block 5 and the second block 14, the first pre-block 4 will be hoisted to the A deck block to form the first block 5, and the third pre-block 13 will be hoisted to the second pre-block 9 to form the second block 14.

Similarly, a preset value is set for the hoisting capacity of the dock hoisting equipment, and when the actual hoisting capacity of the dock hoisting equipment is less than the preset value, it is displayed that the force that can be borne by the dock hoisting equipment is small, and then the above steps are adopted, that is, in addition to the first deck segment, the second deck segment, the third deck segment, the fourth deck segment, the fifth deck segment, the sixth deck segment, the seventh deck segment and the pilot deck segment 10 are respectively carried by the left and right side segments, and the steps are carried out in parallel, thereby improving the efficiency of installation and carrying.
