[0019] By adopting the above technical solutions, the docking gap and flatness are constrained within a certain range, allowing for a certain degree of processing error in the assembly and assembly of the three-dimensional module sections. However, the error is controlled within a manageable range, ensuring the final construction quality of the entire fixed deck area.

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0028] The following will be described in detail with reference to the drawings in the embodiments of the present application. Figs. 1-2 The present application will be further described in detail.
[0029] A construction method of a fixed deck three-dimensional module unit section of a car carrier, comprising the following steps: S1: In the production design stage of the car carrier, the fixed deck and the associated side plate are reasonably segmented and divided; S2: According to the lifting capacity of the dock, the segmented sections after division are planned for unit section scheme, forming a plurality of three-dimensional module unit sections; S3: According to the unit section scheme planning, precision control targets and control essentials are formulated; S4: According to the unit section scheme planning, the design of support scheme and lifting scheme is carried out; S5: According to the design of support scheme and lifting scheme, the plurality of three-dimensional module unit sections are assembled and lifted, and the loading of the fixed deck area of the car carrier is completed.
[0030] This embodiment is illustrated by taking the 463C ship of the 7500PCTC ship as an example. The above-mentioned construction method of the fixed deck three-dimensional module block section of the automobile transport ship divides the construction of the deck area of the automobile transport ship into five steps, reasonably divides the fixed deck and the associated side plate, and then according to the lifting capacity of the dock, the fixed deck and the associated side plate after division are planned into a block section, forming a plurality of three-dimensional module block sections, realizing the modular assembly of the fixed deck area, greatly reducing the lifting frequency and workload, and improving the assembly efficiency of the fixed deck area. At the same time, the segmentation and division work of the fixed deck area in step S1 can be dispersed and carried out simultaneously in other places, instead of being concentrated in the dock, thereby improving the work efficiency and shortening the dock period.
[0031] In step S5, the fixed deck area includes the uppermost movable deck and the fixed deck and the corresponding side plate of several layers above of the automobile transport ship. The three-dimensional module block section includes multiple fixed decks and the side plate connected with the fixed deck.
[0032] The three-dimensional module block section has completed the welding and assembly between the fixed deck and the associated side plate in the segmentation stage, so that the three-dimensional module block section is a real "block section" which has complete structural strength and geometric shape before entering the dock, ensuring the high integrity and high rigidity of the lifting unit. Moreover, the most time-consuming and most demanding welding and assembly work is moved out of the expensive dock period and transferred to the parallel segmentation construction site, which is the fundamental operation to shorten the dock period and improve the efficiency.
[0033] In step S3, the precision control targets include the flatness, perpendicularity and butt joint gap of the butt joint interface of the three-dimensional module block section. The fixed deck is the basis for the parking of vehicles of the automobile transport ship, and the flatness of the butt joint interface can make the fixed deck area have the following advantages: Prevent vehicle rollover: If the deck is locally depressed or inclined, the center of gravity of the parked car may deviate, which may cause a rollover accident; Ensure effective fixation: The vehicle is fixed on the deck by binding belts, and only on a flat base, the binding belts can bear force uniformly and exert maximum restraint; Adapt to lifting structure: For ships equipped with lifting decks, the flatness error of the upper and lower decks needs to be strictly controlled to ensure smooth docking during lifting.
[0034] The perpendicularity of the butt joint interface can make the fixed deck area have the following advantages: Lifting guide: The automobile transport ship often adopts a multi-deck structure, and the column is both a support and a guide rail. If the column is not vertical, the lifting deck will be stuck, rubbed or even collided during movement, resulting in mechanical failure or derailment risk; Structural stress control: the hull belongs to a thin shell structure, and the vertical deviation of the column will cause local stress concentration, leading to steel deformation or fatigue cracks; Equipment installation reference: the installation of vertical components such as crane rails and ventilation ducts is based on this reference, otherwise it will cause subsequent equipment to malfunction.
[0035] Ensure the butt joint gap of the interface, which can make the fixed deck area have the following advantages: Deformation compensation: steel has the characteristics of thermal expansion and cold contraction, and a proper butt joint gap can absorb the expansion and contraction caused by temperature changes, preventing the generation of internal stress that causes deck deformation or cracking; Welding quality: a reasonable gap can ensure the welding depth and weld formation, avoiding incomplete fusion or slag inclusion defects. A large gap will result in insufficient weld strength, and a small gap will easily burn through; Sealing: for weather-tight areas, the butt joint gap needs to be used with sealant to prevent seawater leakage.
[0036] In step S3, the control essentials include using total station and laser tracker instruments for real-time measurement and adjustment when assembling the three-dimensional module total section. The total station is a modern engineering measurement core device. It integrates electronic theodolite, photoelectric range finder and data recording device, and can simultaneously measure angle, distance and height difference, and automatically display three-dimensional coordinates within a few seconds.
[0037] Laser tracker is a high-precision measurement system that integrates laser interference ranging, multi-axis angle coding and digital signal processing. Laser tracker can achieve micron-level positioning accuracy in a large space, and is an indispensable core tool in aerospace, automobile manufacturing and large equipment installation. Through the use of total station and laser tracker instruments, the flatness, perpendicularity and butt joint gap of the three-dimensional module total section assembly can be measured and adjusted in real time.
[0038] The butt joint gap error between the two adjacent three-dimensional module total sections is controlled within ±1.8mm, the flatness error is controlled within ±3.2mm to ±3.8mm, and the perpendicularity error is controlled within 10mm to 15mm. The adjacent two three-dimensional module total sections may have certain processing errors during assembly and assembly, but the error needs to be controlled within a certain range, so that the quality of the three-dimensional module total section assembly is better and the service life is longer.
[0039] In step S4, the support scheme includes adjustable support frames arranged at the bottom of the stereoscopic module unit. When the stereoscopic module unit is assembled at the assembly site, a large number of welding operations between the multiple decks and the hull plates are involved. The welding generates huge thermal stress and shrinkage force. If not constrained, the entire unit will be distorted and deformed uncontrollably, resulting in inaccurate docking with adjacent structures in the dock. The adjustable support frames provide multiple rigid and stable support points at the bottom of the unit, forming a solid "foundation" to effectively resist stress deformation during welding, and are the physical basis for ensuring that the unit maintains the design accuracy after being separated from the cradle.
[0040] In step S4, the lifting scheme adopts a multi-point balanced lifting method, so that the multiple stereoscopic module units are less likely to be deformed, tilted, rolled or locally deformed during lifting, ensuring the lifting quality of the stereoscopic module units. Multi-point balanced lifting is a lifting method that sets multiple lifting points (usually 2, 4 or more) on the object, and uses a balanced beam, a lifting cable and a pulley block to work together. The core purpose is to disperse the load and prevent long, irregular or center-of-gravity-shifted objects from tilting, rolling or locally deforming during lifting.
[0041] In step S2, there are 9 stereoscopic module units, and the average lifting weight of the 9 stereoscopic module units is 333T / lift. At the same time, the loading cycle of the 9 stereoscopic module units only needs 10 days. The stereoscopic module unit divides the fixed deck area into 9 independent modules, and the 9 independent modules can be welded and assembled with the fixed deck and the corresponding side plate. The welding and assembly can be dispersed, and do not need to be concentrated in the dock, thus shortening the welding period. The welded and assembled stereoscopic module units are only 9, which reduces the lifting workload, improves the lifting efficiency and shortens the lifting period.
[0042] The automobile carrier fixed deck stereoscopic module unit construction method is used for the fixed deck of the automobile carrier and the associated side plate area.
[0043] The implementation principle of the embodiment is that: in the step S1 of the automobile transport ship fixed deck three-dimensional module total section construction method, the whole fixed deck area is segmented and divided, and the segmented fixed deck and the associated side plate are welded and assembled in the step; in the step S2, the segmented sections are planned to form nine three-dimensional module total sections, the three-dimensional module total section divides the fixed deck area into nine modules, the assembly of the fixed deck area forms a modular assembly mode, the hoisting workload is reduced, the hoisting period is shortened, the hoisting efficiency is improved, and the assembly and assembly period of the fixed deck area in the dock is shortened; in the step S3, the abutment gap error between the adjacent two three-dimensional module total sections is controlled to be between ±1.8mm, the flatness error is controlled to be between ±3.2mm to ±3.8mm, and the perpendicularity error is controlled to be between 10mm to 15mm by using a total station and a laser tracker and other instruments, so as to ensure the assembly precision and assembly quality of the three-dimensional module total section; in the step S4, a support scheme and a hoisting scheme are designed according to the three-dimensional module total section, the support scheme includes setting an adjustable support frame at the bottom of the three-dimensional module total section, and the hoisting scheme adopts a multi-point balanced hoisting mode, so that the multiple three-dimensional module total sections are not prone to deformation, inclination, lateral turning or local deformation in the hoisting process; and finally, in the step S5, the multiple three-dimensional module total sections are assembled and assembled according to the support scheme and the hoisting scheme, and the construction of the fixed deck area of the automobile transport ship is completed.
