Description

Technical Field

[0001] The invention relates to the technical field of FPSO hull anti-rusting, and in particular to a coating device for FPSO hull anti-rusting. Background Art

[0002] The FPSO (Floating Production Storage and Offloading) hull is an indispensable large-scale facility in offshore oil exploration and development. The FPSO hull is mainly used for oil and gas separation of the extracted oil, treatment of oily wastewater, power generation, heating, and storage and transportation of crude oil products. Anti-rust spraying of the hull is a key measure to ensure the installation of the hull structure and extend its service life. Before anti-rust spraying of the hull, the rust on the hull needs to be polished to improve the adsorption capacity of the hull surface and the paint, and avoid the problem of incomplete adhesion of the paint spraying.

[0003] Due to the large size of the hull and the large amount of oil storage, in the traditional hull anti-rust painting process, rust removal and painting are performed separately. The hull has a large area. When the rust removal work is completed, the previously rust-removed areas may be corroded again. The back and forth processing will increase the workload and increase the entire processing period.

[0004] Before spraying anti-rust work, the hull needs to be polished and rust-removed. During the polishing process of the rusted body by the polishing device, a lot of rust powder is usually produced, and the adsorption of rust powder is strong. After the polishing is completed, the rust powder is usually adsorbed on the hull and the polishing device. If the rust powder is not cleaned in time, the paint and the hull will not be able to stick during spraying, which greatly reduces the anti-rust effect of spraying.

[0005] The hull is usually set in an arc shape, so before the spray device is used for painting, the grinding angle of the grinding and rust removal needs to be adjusted according to the curvature of the hull to avoid incomplete rust removal due to the mismatch between the grinding angle of the grinding device and the hull. At the same time, the spraying angle also needs to be adjusted according to the curvature of the hull during spraying to avoid uneven paint spraying due to mismatch of the spraying angle. Summary of the invention

[0028] When in use: first, the translation wheel 2 drives the base 1 to move to the side of the hull so that the grinding roller 15 faces the hull and the base 1 is parallel to the side of the hull. First, the electric push rod 5 is started to push the universal joint 6 and the fixing plate 7 to move toward the hull. The movement of the fixing plate 7 drives the fixing frame 11 and the limiting wheel 12 to move and contact the hull. After the limiting wheel 12 contacts the hull and is subjected to force, the fixing plate 7 can be driven to rotate to an inclined state through the fixing frame 11 in cooperation with the universal joint 6. After the fixing plate 7 is tilted, the wind shield 8 and the grinding roller 15 are driven to tilt and move to contact the inclined surface of the hull. After the grinding roller 15 contacts the hull and is subjected to force, the pressure on the grinding roller 15 is transmitted to the through-axis pressure sensor 13 through the first fixed shaft 14, and the strain is measured inside the through-axis pressure sensor 13. The change of the sheet resistance value can be used to know the size of the measured mechanical quantity, so as to realize the conversion and measurement of the pressure signal, and thus detect the pressure state of the grinding roller 15. The first servo motor 23 is started to drive the driving wheel 24 and the transmission belt 25 to rotate. The first fixed shaft 14 is driven to rotate along the inner wall of the through-axis pressure sensor 13 through the meshing of the transmission belt 25 and the first driven wheel 26. The grinding roller 15 and the cleaning roller brush 16 are driven to rotate along the surface of the hull through the rotation of the first fixed shaft 14, so that the hull surface can be polished, rusted and cleaned of rust powder. At the same time, the rust powder adsorbed on the surface of the grinding roller 15 and the cleaning roller brush 16 can be self-cleaned through the overlap of the self-cleaning brush 17 with the grinding roller 15 and the cleaning roller brush 16. At the same time, the second driven wheel 27 and the transmission belt The meshing of the second fixed shaft 21 and the fan blades 22 drives the second fixed shaft 21 and the fan blades 22 to rotate along the inner wall of the connecting frame 20, and the rotation of the fan blades 22 sucks the air inside the filter collection box 19. After the inside of the filter collection box 19 is in a negative pressure state, the rust powder generated by grinding and cleaning the surface of the hull is sucked through the suction pipe 18 and the wind cover 8, and then the rust powder is filtered and collected through the filter bag and the filter membrane arranged inside the filter collection box 19. The second servo motor 34 is started to drive the worm 35 to rotate, and the meshing of the worm 35 and the worm wheel 36 drives the threaded rod 32 to rotate along the inner wall of the limit ring 31. The threaded connection between the threaded rod 32 and the threaded sleeve 33 drives the lifting plate 4 to slide upward along the inner wall of the limit frame 3, and the movement of the lifting plate 4 drives the electric push rod 5, the universal joint 6, and the fixed The plate 7, the wind hood 8, the grinding roller 15 and the cleaning roller brush 16 are moved upward to adjust the grinding height. Since the hull has an arc, the distance between the fixed plate 7 and the hull will gradually decrease during the rising process, so the pressure on the grinding roller 15 will gradually increase. When the through-axis pressure sensor 13 detects the increase in pressure, the electric push rod 5 is automatically recovered to increase the distance between the fixed plate 7 and the hull to adjust the stress state of the grinding roller 15. At the same time, the tension generated by the rebound of multiple adjustment springs 10 can be used to automatically adjust the inclination of the fixed plate 7 to adapt to the curvature of the hull. Through the rotation adjustment of the fixed plate 7 and the expansion and contraction of the bellows 29, the spraying direction of the atomizing nozzle 30 can be adjusted to remain perpendicular to the hull. The sprayer 28 drives the air distribution reversing device by controlling the airflow.The piston of the pneumatic motor makes a stable and continuous reciprocating motion, pressurizes the paint and delivers it to the atomizing nozzle 30 through the bellows 29. The atomizing nozzle 30 atomizes the paint and sprays it onto the hull, so that the hull after grinding and cleaning can be painted and rust-proofed.
