[0002] Shipbuilding refers to the production industry of building or manufacturing ships, which is usually carried out in the slipway or dock of a professional shipyard. The technology used in shipbuilding itself is very extensive, from the hull to the use of the engine.

[0038] The mounting frame 2 is moved by the AGV driving trolley 1. The AGV driving trolley 1 is a prior art and will not be described in detail here. The mounting frame 2 is moved around the hull, and then the transmission block 3 is driven up and down by the driving mechanism. The transmission block 3 drives the electric telescopic rod 4 and the mounting plate 5 to move to the position where paint is required. Then, the mounting plate 5 is driven to move by the electric telescopic rod 4.

[0039] Embodiment 2

[0040] Based on Example 1, please refer to Figure 3 , Figure 4 and Fig. 9As shown, the spraying mechanism includes a plurality of first transmission columns 11 slidably connected to the mounting plate 5, the outer surface of the first transmission column 11 is fixedly sleeved with a first spring 12 fixedly connected to the mounting plate 5, one end of the first transmission column 11 is fixedly connected to a roller 13, one end of the first transmission column 11 is fixedly connected to a connecting plate 14, one side of the connecting plate 14 is fixedly connected to a spray pipe 15 slidably connected to the mounting plate 5, one end of the spray pipe 15 is fixedly connected to a spray head 16, the outer surface of the spray pipe 15 is fixedly sleeved with a second spring 17 fixedly connected to the mounting plate 5, the outer surface of the spray pipe 15 is fixedly connected to a first connecting pipe 18 fixedly connected to the mounting plate 5 through a hose, one end of the first connecting pipe 18 is fixedly connected to a sprayer fixedly connected to the AGV driving trolley 1 through a hose, and the connecting plate 14 is transmission-connected to a grinding and polishing mechanism on the mounting plate 5;

During the movement, the roller 13 on the first transmission column 11 on the mounting plate 5 first fits with the hull, so that the rollers 13 on multiple first transmission columns 11 are all fitted on the surface of the hull. When the position on the hull is more protruding, the first transmission column 11 is driven to move outward by a larger distance, and when it is more concave, the moving distance is smaller. At this time, the first spring is compressed 12, and the first transmission column 11 drives the spray pipe 15 to move through the connecting plate 14 while moving, and the second spring 17 is compressed to make the spray pipe 15 at the more protruding position move outward. The spray heads 16 on the coating tubes 15 are farther away from the hull and closer, so that the spray heads 16 on each spray tube 15 are at the same distance from the hull surface. Then the AGV drives the trolley 1 to drive the mounting frame 2 to move, and the roller 13 on the first transmission column 11 rolls on the hull, so that the spray heads 16 automatically adjust the positions of the spray heads 16 during the spraying of the curved hull surface, so that the distances between the multiple spray heads 16 and the hull are kept consistent. At the same time, the sprayer supplies paint to each spray tube 15 through the first connecting pipe 18 and the hose, and then the paint is evenly sprayed on the hull surface through the spray heads 16, thereby greatly improving the spraying effect on the hull surface.

[0042] Embodiment 3

[0043] Based on Example 1, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the grinding and polishing mechanism includes a support plate 21 fixedly connected to the mounting plate 5, two transmission rollers 22 are rotatably connected to the support plate 21, an elastic rubber belt 23 is transmission-connected between the two transmission rollers 22, a plurality of grinding sandpaper strips 24 are fixedly connected to the outer surface of the elastic rubber belt 23 by bolts, one end of one of the transmission rollers 22 is fixedly connected to a first transmission motor 25 by a coupling, an agitation and fitting mechanism connected to the connecting plate 14 is provided on the mounting plate 5, the agitation and fitting mechanism is used to drive the elastic rubber belt 23 to push, so that the grinding sandpaper strips 24 on the elastic rubber belt 23 are attached to the hull, and a cleaning mechanism is provided on the mounting plate 5, the cleaning mechanism is used to clean and collect dust after grinding and polishing;

[0044] The agitation and laminating mechanism comprises a first transmission box 31 fixedly connected to the mounting plate 5, a first elastic airbag 32 is fixedly connected to one side of the first transmission box 31, the outer surface of the first elastic airbag 32 is rotatably connected to a plurality of supporting rollers rollingly connected to the elastic rubber belt 23, a second transmission box 33 fixedly connected to the mounting plate 5 is fixedly connected to one side of the first transmission box 31 through a pipeline, a second elastic airbag 34 is fixedly connected in the second transmission box 33, the outer surface of the second elastic airbag 34 is coated with grease, transmission fluid is arranged in the first transmission box 31 and the second elastic airbag 34, a second transmission column 35 fixedly connected to the connecting plate 14 is slidably connected to the second transmission box 33, an extrusion plate 36 is fixedly connected to one end of the second transmission column 35, a buffer mechanism is arranged on one side of the first transmission box 31, the buffer mechanism is used to buffer the first elastic airbag 32, the buffer mechanism comprises a buffer tube 71 fixedly connected to the first transmission box 31, a buffer plate 72 is slidably connected in the buffer tube 71, and a third spring 73 fixedly connected to the buffer tube 71 is fixedly connected to one side of the buffer plate 72;

[0045] Before spraying, the mounting plate 5 is driven to move by the electric telescopic rod 4, so that the rollers 13 on the multiple first transmission columns 11 on the mounting plate 5 are all in contact with the surface of the hull. At this time, the first transmission column 11 drives the connecting plate 14 to move, and the connecting plate 14 drives the second transmission column 35 to move. The second transmission column 35 drives the extrusion plate 36 to move, and the extrusion plate 36 squeezes the second elastic airbag 34 to transport the transmission fluid in the second elastic airbag 34 to the first transmission box 31 through the pipeline. At this time, the transmission fluid in the first transmission box 31 rises, driving the first elastic airbag 32 on the first transmission box 31 to swell. At this time, the first elastic airbag 32 drives the elastic rubber belt 23 to move through the supporting roller, so that the elastic rubber belt 23 drives the grinding sandpaper strip 24 to fit the surface of the hull according to the curved surface of the hull. At the same time, when too much transmission fluid is squeezed into the first transmission box 31, the elastic airbag 32 The rubber belt 23 and the grinding sandpaper strip 24 have been completely attached to the surface of the hull. At this time, the internal pressure of the first transmission box 31 is too high, which will cause the grinding sandpaper strip 24 to fit too tightly. At this time, the transmission fluid enters the buffer tube 71, and the pressure is greater than the elastic coefficient of the third spring 73 in the buffer tube 71. At this time, the buffer plate 72 in the buffer tube 71 is pushed, and the third spring 73 is stretched to prevent the grinding sandpaper strip 24 from fitting too tightly to the surface of the hull, so that the elastic rubber belt 23 drives the grinding sandpaper strip 24 to grind the hull. Subsequently, the transmission roller 22 is driven to rotate by the first transmission motor 25, and the transmission roller 22 drives the elastic rubber belt 23 to rotate, and the elastic rubber belt 23 drives the grinding sandpaper strip 24 to move, and the grinding sandpaper strip 24 grinds the rust stains on the surface of the hull, so as to grind the surface of the hull according to the curve of the surface of the hull, thereby achieving sufficient grinding of the rust on the surface of the hull.

[0046] Embodiment 4

[0047] Based on Example 3, please refer to Figure 4 , Figure 5 and Fig.10As shown, the cleaning mechanism includes a plurality of transmission tubes 41 rotatably connected to the mounting plate 5, and the plurality of transmission tubes 41 are connected to each other through transmission wheels and transmission belts. A second transmission motor 42 is fixedly connected to one side of the mounting plate 5, and an output end of the second transmission motor 42 is fixedly connected to a first transmission shaft 43 through a coupling. An outer surface of the first transmission shaft 43 is connected to one of the transmission tubes 41 through a transmission wheel and a transmission belt. A plurality of cleaning brush plates 44 are fixedly connected to one end of the transmission tube 41. A dust collection mechanism connected to the mounting plate 5 is provided on the transmission tube 41. The dust collection mechanism is used to collect the cleaned dust. The dust collection mechanism includes a second transmission shaft 51 rotatably connected to the mounting plate 5, and an outer surface of the second transmission shaft 51 is connected to the outer surface of the second transmission shaft 51. The surface is connected to the transmission tube 41 through a transmission wheel and a transmission belt. The outer surface of the second transmission shaft 51 is fixedly sleeved with a first gear 52, and the outer surface of the first gear 52 is meshingly connected with a second gear 53. The second gear 53 is fixedly sleeved with a third transmission shaft 54 ​​rotatably connected to the transmission tube 41, and the outer surface of the third transmission shaft 54 ​​is fixedly sleeved with a fan blade 55. The transmission tube 41 is rotatably connected with a second connecting tube 56, and the outer surface of the second connecting tube 56 is fixedly connected with a third connecting tube 57 fixedly connected to the mounting plate 5, and one end of the third connecting tube 57 is fixedly connected to a collecting box 58, and an exhaust groove is provided on one side of the collecting box 58. A filter screen is fixedly connected inside the collecting box 58, and a cleaning door is provided on the collecting box 58.

[0048] During the grinding process, the first transmission shaft 43 is driven to rotate by the second transmission motor 42, and the first transmission shaft 43 drives one of the transmission tubes 41 to rotate through the transmission wheel and the transmission belt. At the same time, the transmission tubes 41 are driven by each other through the transmission wheel and the transmission belt. The transmission tube 41 drives the cleaning brush plate 44 to rotate, and the cleaning brush plate 44 cleans the rust on the surface of the hull after grinding. At the same time, while cleaning, the transmission tube 41 drives the second transmission shaft 51 to rotate through the transmission wheel and the transmission belt, and the second transmission shaft 51 drives the third transmission shaft 54 ​​to rotate rapidly through the first gear 52 and the second gear 53, and the third transmission shaft 54 ​​drives the fan blades 55 to rotate rapidly in the transmission tube 41. At this time, the transmission tube 41 sucks air, and the transmission tube 41 inhales the cleaned dust, and then the dust is sucked into the collection box 58 through the second connecting pipe 56 and the third connecting pipe 57 for collection, thereby achieving sufficient and timely cleaning of the rust dust polished off, effectively reducing the impact of dust on subsequent spraying.

[0049] The working principle of the present invention is as follows: the AGV drives the trolley 1 to move the mounting frame 2 to the spraying position, and then the electric telescopic rod 4 drives the mounting plate 5 to move. During the movement, the roller 13 on the first transmission column 11 on the mounting plate 5 first fits with the hull, so that the rollers 13 on multiple first transmission columns 11 are all fitted on the surface of the hull. When the position on the hull is more convex, the first transmission column 11 is driven to move outward by a larger distance, and when it is more concave, the moving distance is smaller. At this time, the first spring is compressed 12, and the first transmission column 11 drives the spraying pipe 15 to move through the connecting plate 14 while moving, and the second spring 17 is compressed to make the more convex position The spray heads 16 on the spray tubes 15 in the out position are far away from the hull, and vice versa, so that the spray heads 16 on each spray tube 15 are at the same distance from the hull surface. Then the AGV drives the trolley 1 to drive the mounting frame 2 to move, and the roller 13 on the first transmission column 11 rolls on the hull, so that the spray heads 16 automatically adjust the position of the spray heads 16 during the spraying of the curved hull surface, so that the distance between the spray heads 16 and the hull is consistent. At the same time, the sprayer supplies paint to each spray tube 15 through the first connecting pipe 18 and the hose, and then the paint is evenly sprayed on the hull surface through the spray heads 16, which greatly improves the spraying effect on the hull surface.

[0050] Before spraying, the mounting plate 5 is driven to move by the electric telescopic rod 4, so that the rollers 13 on the multiple first transmission columns 11 on the mounting plate 5 are all in contact with the surface of the hull. At this time, the first transmission column 11 drives the connecting plate 14 to move, and the connecting plate 14 drives the second transmission column 35 to move. The second transmission column 35 drives the extrusion plate 36 to move, and the extrusion plate 36 squeezes the second elastic airbag 34 to transport the transmission fluid in the second elastic airbag 34 to the first transmission box 31 through the pipeline. At this time, the transmission fluid in the first transmission box 31 rises, driving the first elastic airbag 32 on the first transmission box 31 to swell. At this time, the first elastic airbag 32 drives the elastic rubber belt 23 to move through the supporting roller, so that the elastic rubber belt 23 drives the grinding sandpaper strip 24 to fit the surface of the hull according to the curved surface of the hull. At the same time, when too much transmission fluid is squeezed into the first transmission box 31, the elastic airbag 32 The rubber belt 23 and the grinding sandpaper strip 24 have been completely attached to the surface of the hull. At this time, the internal pressure of the first transmission box 31 is too high, which will cause the grinding sandpaper strip 24 to fit too tightly. At this time, the transmission fluid enters the buffer tube 71, and the pressure is greater than the elastic coefficient of the third spring 73 in the buffer tube 71. At this time, the buffer plate 72 in the buffer tube 71 is pushed, and the third spring 73 is stretched to prevent the grinding sandpaper strip 24 from fitting too tightly to the surface of the hull, so that the elastic rubber belt 23 drives the grinding sandpaper strip 24 to grind the hull. Subsequently, the transmission roller 22 is driven to rotate by the first transmission motor 25, and the transmission roller 22 drives the elastic rubber belt 23 to rotate, and the elastic rubber belt 23 drives the grinding sandpaper strip 24 to move, and the grinding sandpaper strip 24 grinds the rust stains on the surface of the hull, so as to grind the surface of the hull according to the curve of the surface of the hull, thereby achieving sufficient grinding of the rust on the surface of the hull.
