When the living building is hoisted and the lower end of the living building moves down between the two side guide rollers, when the positioning pin is removed, the No. 2 driving handle is turned to drive the drive shaft and the gear sleeve to rotate synchronously. By rotating the gear sleeve a certain number of circles, the two driving cross bars can pull the two No. 2 side shaft rods and the side guide rollers closer to each other and move them a certain distance quantitatively through the adjustment block, so as to adjust the left and right position of the living building, so that the left and right position of the living building between the two side guide rollers is accurate, and the staff does not need to adjust it all the time, which saves time and effort and ensures the safety of the staff.

[0021] 3. The integrated superstructure structure of the large floating production storage and offloading vessel, in daily work, adjust the front guide roller and the side guide roller away from the living building, the middle mounting plate, the side mounting plate and the adjustment guide mechanism cooperate with each other, can effectively play the role of guardrail, when encountering strong winds and waves, adjust the front guide roller and the side guide roller to be close to the living building, and then the front guide roller and the side guide roller can effectively stabilize the living building. The living building is produced by modular technology, which means that the structure, equipment and system of the living building are decomposed into several relatively independent units with interface relationships according to function or hierarchical system, and then arranged and combined into the whole living building in different ways according to the design and production principles of standardization, generalization, serialization and combination. The modular technology of the living building can complete the installation of outfitting equipment to the greatest extent before the assembly of the total section, improve the construction quality and outfitting rate, and shorten the construction period.

[0040] Among them, the front and rear position adjustment component 7 also includes a connecting plate 702, a driving screw 706 and a No. 1 driving handle 707. The connecting plate 702 is arranged at the end of the limiting slide bar 701 away from the mounting block 703. The driving screw 706 is threadedly connected to the connecting plate 702. One end of the driving screw 706 is rotatably connected to the intermediate mounting plate 5 through a bearing. The end of the driving screw 706 away from the intermediate mounting plate 5 passes through the connecting plate 702 and is connected to the No. 1 driving handle 707. Both sides of the upper end of the mounting block 703 are provided with a No. 1 side shaft rod 704. The outer surface of the No. 1 side shaft rod 704 is rotatably sleeved with a front guide roller 705. Driving the No. 1 driving handle 707 to rotate can drive the driving screw 706 to rotate synchronously, and under the limiting action of the limiting slide 701, the connecting plate 702 can be moved along the driving screw 706.

By providing the positioning pin 805 and the positioning hole 105, when the front end of the positioning pin 805 is inserted into the positioning hole 105, the rotation of the drive shaft 801 can be effectively restricted. When the living building 2 is hoisted and the lower end of the living building 2 moves down to between the two side guide rollers 810, when the positioning pin 805 is removed, rotating the No. 2 driving handle 803 can drive the drive shaft 801 and the gear sleeve 802 to rotate synchronously.

[0042] Among them, a limiting protrusion 601 is provided at the middle end of the back side of the side mounting plate 6, and two guide sliding holes 602 are provided on the limiting protrusion 601. Driving cross bars 806 are provided at the upper and lower ends of the gear sleeve 802, and tooth grooves 807 are provided on the driving cross bar 806.

At this time, the vertical strip of the L-shaped strip seat 401 is inserted into the inner slot 102, which can effectively prevent the hull guardrail 4 from shaking, and then the fixing bolt 402 is threadedly connected to the oil storage and unloading hull 1 through the bolt hole 103, further ensuring the stability of the hull guardrail 4. Since the hull guardrail 4 is assembled by docking a plurality of split short guardrails, it can be disassembled and replaced in time when it is damaged somewhere.

[0044] Working principle: when the front end of the positioning pin 805 is inserted into the positioning hole 105, the rotation of the drive shaft 801 can be effectively restricted. When the living building 2 is hoisted and the lower end of the living building 2 moves down to between the two side guide rollers 810, when the positioning pin 805 is removed, the No. 2 driving handle 803 is rotated to drive the drive shaft 801 and the gear sleeve 802 to rotate synchronously. By rotating the gear sleeve 802 a certain number of times, the two driving cross bars 806 can pull the two No. 2 side shafts 809 and the side guide rollers 810 closer to each other and move them a certain distance quantitatively through the adjustment block 808, so as to adjust the left and right positions of the living building 2 so that the living building 2 between the two side guide rollers 810 is not in a stable position. The left and right positions of the living building 2 are accurate. By driving the No. 1 driving handle 707 to rotate, the driving screw 706 can be driven to rotate synchronously. Under the limiting action of the limiting slide 701, the connecting plate 702 can be moved along the driving screw 706. During the movement of the connecting plate 702, the mounting block 703 can be effectively driven to move synchronously through the limiting slide 701. During the movement of the mounting block 703, the front guide roller 705 can be driven to move synchronously through the No. 1 side shaft 704 to adjust the front and rear positions of the front guide roller 705 to ensure that during the process of lifting the living building 2 downward, the front guide roller 705 can guide the living building 2 to ensure the accurate front and rear positions of the living building 2.

[0045] Furthermore, when installing the hull guardrail 4, by inserting the horizontal strip of the L-shaped clamping strip seat 401 into the strip installation groove 101, at this time, the vertical strip of the L-shaped clamping strip seat 401 is inserted into the inner clamping groove 102, which can effectively prevent the hull guardrail 4 from shaking, and then the fixing bolt 402 is threadedly connected to the oil storage and unloading hull 1 through the bolt hole 103, further ensuring the stability of the hull guardrail 4. Since the hull guardrail 4 is assembled by docking a plurality of split short guardrails, it can be disassembled and replaced in time when it is damaged somewhere. In daily work, adjust the front guide roller 705 and the side guide roller 810 away from the living building 2, and the middle mounting plate 5, the side mounting plate 6 and the adjustment guide mechanism cooperate with each other, which can effectively play a role. Guardrail function: when encountering strong winds and choppy weather, adjust the front guide roller 705 and the side guide roller 810 to be close to the living building 2, and then the front guide roller 705 and the side guide roller 810 can effectively stabilize the living building 2. The living building 2 is produced by modular technology, which means that the structure, equipment and system of the living building 2 are decomposed into several relatively independent units with interface relationships according to functions or hierarchical systems, and then arranged and combined into the whole of the living building 2 in different ways according to the design and production principles of standardization, generalization, serialization and combination. The modular technology of the living building 2 can complete the installation of outfitting equipment to the greatest extent before the assembly of the total section, thereby improving the construction quality and outfitting rate and shortening the construction period.
