Description

Technical Field

[0001] This invention belongs to the field of generators and relates to painting technology, specifically a painting device for processing the casing of a gas generator set. Background Technology

[0002] Gas generator sets are a new type of generator set developed to meet global environmental protection requirements and the new market environment. A gas generator set generally consists of an engine, generator, integrated control system, oil circuit system, and power distribution system. The gas engine and generator are mounted on the same steel chassis. The unit uses combustible gases such as natural gas, associated gas from wellheads, and coal mine methane as fuel. Due to the increased voltage level of the generator, its insulation requirements are higher. Furthermore, to improve the generator's service life and prevent electrostatic aging, the gas generator casing needs to be painted.

[0003] In existing technologies, generator set casings are generally painted using spray nozzles. This requires hoisting the generator set casing and then having an employee manually spray paint it with a spray gun. However, the following problems still exist:

[0004] When employees use a spray gun to paint the generator set casing, some paint may not be sprayed onto the casing during the spraying process. At the same time, the paint sprayed on the surface of the generator set casing will drip down, and the excess paint cannot be recycled, resulting in paint waste. Summary of the Invention

[0005] The purpose of this application is to provide a painting device for processing the casing of a gas generator set, which solves the problem that some of the paint sprayed from the spray gun does not reach the generator set casing, and the paint sprayed on the surface of the generator set casing drips down with the surface, making it impossible to recycle the excess paint.

[0006] To achieve the above objectives, this application provides a painting device for processing the casing of a gas generator set, comprising a cylindrical paint-holding shell, one side of which is open. A support member is installed at the bottom of the paint-holding shell, and the generator set casing is placed on the support member. A painting moving member is disposed on the paint-holding shell and moves along the side wall of the paint-holding shell. The painting moving member moves circumferentially around the axis of the paint-holding shell. The painting moving member includes a moving frame and a first spur gear rotatably connected to each other. A toothed block is fixedly connected to the outer side wall of the paint-holding shell, and the first spur gear meshes with the toothed block. A paint pump is fixedly installed on the mobile frame. The input end of the paint pump is located at the bottom end of the paint holding shell. A spray gun is fixedly connected to the output end of the paint pump. The spray gun is fixedly connected to the mobile frame. A spray nozzle is fixedly connected to the side of the spray gun facing the generator set housing. The support member includes a fixed platform and a support plate fixedly connected to each other. The fixed platform is fixedly connected to the inner bottom wall of the paint holding shell. The support plate is evenly distributed about the axis of the fixed platform. Multiple notches are opened on the side of the support plate facing the opening of the paint holding shell. The fixed platform is inclined downwards.

[0007] Preferably, a drive motor is fixedly mounted on the mobile frame, and the output end of the drive motor is fixedly connected to the first spur gear.

[0008] Preferably, a guide wheel is rotatably connected to one side of the movable frame, and the side wall of the guide wheel is in close contact with the inner side wall of the paint container.

[0009] Preferably, a third spur gear is fixedly connected to the middle of the guide wheel via a shaft, a rotating column is rotatably connected to the side wall of the movable frame, a second spur gear is fixedly connected to the outer side wall of the rotating column, the second spur gear and the third spur gear mesh with each other, and a stirring blade is fixedly connected to the outer side wall of the rotating column.

[0010] Preferably, the axes of the fixing platform and the paint container coincide.

[0011] Preferably, the support plate has through holes.

[0012] Preferably, an arc-shaped block is fixedly connected to the outer side of the support plate, and a groove is opened on the side wall of the stirring blade. The groove is located at the bottom and side of the stirring blade, and the groove at the side end has the same shape as the arc-shaped block and is compatible with it.

[0013] Preferably, the arc-shaped block is inclined upwards.

[0014] Preferably, a paint extraction tube is provided in the middle of the rotating column, one end of the paint extraction tube is fixed to the input end of the paint pump, and the other end of the paint extraction tube extends into the paint at the bottom of the paint container.

[0015] Preferably, there are multiple spray nozzles, which are evenly distributed on the paint spray bar.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] By setting up a paint collection shell and supporting components, the supporting components include a fixed platform and a support plate that are fixedly connected to each other. The support plate has multiple notches on the side facing the opening of the paint collection shell. These notches facilitate the placement of different models of generator set housings. After the spray nozzle sprays paint onto the outer wall of the generator set housing, the paint on the generator set housing slowly drips down the surface onto the fixed platform. Because the fixed platform is inclined downwards, there is a gap between every two adjacent support plates, which causes the paint dripping onto the surface of the fixed platform to slowly flow towards the side wall of the paint collection shell, making it easy to recycle and saving resources.

[0018] By incorporating a painting moving component, which includes a movable frame and a first spur gear rotatably connected to each other, and a guide wheel rotatably connected to one side of the movable frame, the guide wheel drives the third spur gear to rotate. The rotation of the third spur gear drives the second spur gear to rotate, which in turn drives the rotating column to rotate. When the rotating column rotates, it drives multiple stirring blades to rotate. The rotation of the stirring blades stirs the paint contained at the bottom of the paint container. During the entire painting process, the movable frame moves in a circular motion along the outside of the generator set casing. The movement of the movable frame, in turn, drives the stirring blades to rotate. This achieves the effect of stirring the paint in the paint container every time the generator set casing is painted, effectively preventing paint sedimentation, improving the quality of the mixed paint, and slowing down the solidification speed of the paint.

[0019] By setting the slot and the arc-shaped block, the stirring blade rotates and stirs the paint at the bottom of the paint container. The slot is used to reduce the resistance of the paint to the stirring blade. When the paint level in the paint container drops, the arc-shaped block is used to prevent the paint in the side slot from solidifying. The bottom slot reduces the stirring of the paint near the end of the paint extraction tube, so as to avoid affecting the amount of paint extracted by the paint extraction tube and thus the spraying effect.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please refer to the details. Figure 1 A painting device for processing the casing of a gas generator set includes a cylindrical paint container 1 with one side open. A support member 3 is installed at the bottom of the paint container 1, and a generator set casing 4 is placed on the support member 3. The paint container 1 is used to hold paint, and the support member 3 is used to support and limit the generator set casing 4. A painting moving member 2 is provided on the paint container 1 and moves along the side wall of the paint container 1. The painting moving member 2 moves circumferentially around the axis of the paint container 1.

[0031] As one implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, the painting moving part 2 includes a moving frame 7 and a first spur gear 8 rotatably connected to each other. The moving frame 7 is engaged with the opening of the paint container 1. Multiple toothed blocks 13 are fixedly connected to the outer wall of the paint container 1 and are evenly distributed on the paint container 1. The first spur gear 8 meshes with the toothed blocks 13. A drive motor 9 is fixedly mounted on the moving frame 7, and the output end of the drive motor 9 is fixedly connected to the first spur gear 8. When the drive motor 9 starts, it drives the first spur gear 8 to rotate. The rotation of the first spur gear 8 cooperates with the toothed blocks 13, thereby causing the moving frame 7 to perform a circular motion about the axis of the paint container 1. A paint pump 10 is fixedly mounted on the moving frame 7. The input end of the paint pump 10 is located at the bottom end of the paint container 1, and the output end of the paint pump 10 is fixedly connected to the paint spraying rod 11. The paint spraying rod 11 is fixedly connected to the moving frame 7. The side of the paint spraying rod 11 facing the generator housing 4 is fixedly connected to the nozzle 12. There are multiple nozzles 12, which are evenly distributed on the paint spraying rod 11. When the moving frame 7 moves in a circular motion about the paint container 1, the moving frame 7 drives the paint pump 10, the paint spraying rod 11 and the nozzle 12 to move. The nozzle 12 sprays paint on the outer wall of the generator housing 4. At the same time, the moving frame 7 drives the paint spraying rod 11 and the nozzle 12 to rotate about the axis of the generator housing 4, so that the outer wall of the generator housing 4 can be quickly painted.

[0032] As one implementation method in this embodiment, such as Figure 2 , Figure 3 and Figure 6As shown, a guide wheel 19 is rotatably connected to one side of the movable frame 7. The side wall of the guide wheel 19 is in close contact with the inner side wall of the paint container 1. A flange is provided on one side of the guide wheel 19. An annular groove adapted to the flange of the guide wheel 19 is opened on the inner side wall of the paint container 1. A third spur gear 21 is fixedly connected to the middle of the guide wheel 19 via a shaft. A rotating column 22 is rotatably connected to the side wall of the movable frame 7. A second spur gear 20 is fixedly connected to the outer side wall of the rotating column 22. The second spur gear 20 and the third spur gear 21 mesh with each other. When the drive motor 9 is started, the drive motor 9 drives the movable frame 7 to make a circular motion along the opening of the paint container 1 through the cooperation of the first spur gear 8 and the gear block 13. The guide wheel 19 rotates about the side wall of the paint container 1. The guide wheel 19 is used to increase the stability of the movable frame 7 during the movement. When the guide wheel 19 rotates, the guide wheel 19... The rotation of the third spur gear 21 causes the second spur gear 20 to rotate, which in turn causes the rotating column 22 to rotate. A stirring blade 14 is fixedly connected to the outer wall of the rotating column 22. Multiple stirring blades 14 are evenly distributed on the rotating column 22. When the rotating column 22 rotates, it drives the stirring blades 14 to rotate, which in turn stirs the paint contained at the bottom of the paint container 1. During the entire painting process, the moving frame 7 moves in a circular motion along the outside of the generator set housing 4. The movement of the moving frame 7 also drives the stirring blades 14 to rotate. This achieves the effect of stirring the paint in the paint container 1 each time the generator set housing 4 is painted, effectively preventing paint sedimentation, improving the quality of the mixed paint, and slowing down the solidification speed of the paint.

[0033] As one implementation method in this embodiment, such as Figures 1-5 As shown, the support member 3 includes a fixed platform 5 and a support plate 6 that are fixedly connected to each other. The fixed platform 5 is fixedly connected to the inner bottom wall of the paint collection shell 1. The axes of the fixed platform 5 and the paint collection shell 1 coincide. There are multiple support plates 6, which are evenly distributed about the axis of the fixed platform 5. Multiple notches 18 are opened on the side of the support plate 6 facing the opening of the paint collection shell 1. One end of the generator set housing 4 is stuck on the multiple notches 18 located on the same circle, thereby supporting the first spur gear 8 and facilitating subsequent painting. The multiple notches 18 facilitate the placement of different models of generator set housings 4, increasing the applicability of the placement of generator set housings 4. The outside of the fixed platform 5 is inclined downwards. When the spray nozzle 12 sprays paint towards the outer wall of the generator set housing 4, the paint on the generator set housing 4 slowly drips down the surface onto the fixed platform 5. Since the outside of the fixed platform 5 is inclined downwards, there is a gap between every two adjacent support plates 6, which causes the paint dripping onto the surface of the fixed platform 5 to slowly flow towards the side wall of the paint collection shell 1, which is convenient for recycling and saves resources.

[0034] As one implementation method in this embodiment, such as Figures 2-5and Figure 7 As shown, the support plate 6 has through holes 17, which are used to increase the flowability of paint in the paint container 1 and reduce the material used in the support plate 6. An arc-shaped block 16 is fixedly connected to the outside of the support plate 6. The arc-shaped block 16 strengthens the support of the generator set housing 4 placed outside the support plate 6, improving the stability of the support. The side wall of the stirring blade 14 has slots 15, which are located at the bottom and side ends of the stirring blade 14. The side slots 15 have the same shape as the arc-shaped block 16 and are compatible with each other. The size of the slots 15 is larger than the size of the arc-shaped block 16. When the stirring blade 14 rotates, the stirring blade 1... 4. The paint at the bottom of the paint container 1 is stirred. The groove 15 is used to reduce the resistance of the paint to the stirring blade 14. When the paint level in the paint container 1 drops, the arc block 16 is used to prevent the paint in the side groove 15 from solidifying, which would increase the resistance of the stirring blade 14. A paint extraction pipe 23 is provided in the middle of the rotating column 22. One end of the paint extraction pipe 23 is fixed to the input end of the paint pump 10, and the other end of the paint extraction pipe 23 extends into the paint at the bottom of the paint container 1. When the stirring blade 14 rotates, the groove 15 at the bottom reduces the stirring of the paint near the end of the paint extraction pipe 23 to avoid affecting the amount of paint extracted by the paint extraction pipe 23, so as not to affect the spraying effect.

[0035] The working principle of this invention is as follows: First, personnel hoist the generator set housing 4 onto the corresponding notch 18. The notch 18 limits the position of the generator set housing 4, and the support plate 6 supports the generator set housing 4. Next, the drive motor 9 and paint pump 10 are started. The drive motor 9 drives the first spur gear 8 and the gear block 13 to engage, causing the moving frame 7 to rotate around the axis of the paint container 1. The paint pump 10 starts and extracts paint from the bottom of the paint container 1 through the paint extraction pipe 23. After extraction, the paint is applied through the spray nozzle. The nozzle 12 sprays paint onto the outer wall of the generator housing 4. During the spraying process, the moving frame 7 drives the paint spray bar 11 and the nozzle 12 to make a circular motion around the generator housing 4, so that the paint can be sprayed evenly and quickly onto the outer wall of the generator housing 4, which speeds up the spraying efficiency. The movement of the moving frame 7 also drives the stirring blade 14 to rotate. Each time the generator housing 4 is sprayed, the paint in the paint container 1 can be stirred, which effectively prevents the paint from settling, improves the quality of the mixed paint, and slows down the solidification speed of the paint.
