Description

Technical Field

[0001] This invention relates to the field of iron outfitting technology, and in particular to an anti-corrosion coating device for the surface of ship iron outfitting. Background Technology

[0002] Due to the harsh working environment on ships, the outer surface of marine iron outfitting components usually needs to be coated with an anti-corrosion coating during production. The anti-corrosion coating can effectively prevent the mooring bollards and other marine iron outfitting components from being damaged by rust.

[0003] A search revealed Chinese patent CN114226150A, which discloses a surface anti-corrosion coating device for processing marine iron outfitting parts. This device involves sliding a dyeing tank inside a main tank and fixing the pump unit's suction end to the lower outer wall of the main tank. Hot water can be pumped in to control the contact between the iron outfitting parts and the anti-corrosion coating, eliminating the need for actively moving the parts during dyeing. The injected hot water also prevents the anti-corrosion coating inside the dyeing tank from solidifying and flocculating due to the cold external environment. A main shaft, passing through the dyeing tank and rotatably connected to the center of the main tank, ensures more even contact between the outer surface of the iron outfitting parts and the anti-corrosion coating. This also facilitates the removal of excess coating by centrifugal force after dyeing, saving coating and reducing production costs.

[0004] In the aforementioned existing technical solution, the ship's iron outfitting parts to be coated are placed on top of a placement platform, and then the platform is moved downwards to immerse the iron outfitting parts in pigment, thus completing the coating work. However, in actual use, after the iron outfitting parts are coated, they need to be removed, repositioned, or reinstalled, and then re-coated in the main container. The process of removing and installing the iron outfitting parts wastes a lot of time, increases the production cost of anti-corrosion coating on the surface of the iron outfitting parts, and affects the coating efficiency. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes an anti-corrosion coating device for ship iron outfitting components. A drive assembly drives driven gears to rotate. Since the two driven gears rotate in opposite directions, the ship iron outfitting components inside the two coating cylinders move in opposite directions. The first coating cylinder performs the addition and removal of ship iron outfitting components, while the second coating cylinder performs the coating operation on the ship iron outfitting components, thus improving the coating efficiency of ship iron outfitting components.

[0006] The technical solution to achieve the purpose of this invention is: a surface anti-corrosion coating device for ship iron outfitting, including a receiving box, a driving component and a coating component extending into the receiving box are provided on the outside of the receiving box, a pumping component is provided inside the receiving box, a positioning component is provided inside the coating cylinder, and the driving component includes;

[0007] The package includes a fixed housing, a drive gear, and a drive motor. The fixed housing is fixedly installed on the outer side wall of the receiving box, the drive motor is fixedly installed on the top wall of the fixed housing, and the drive gear is rotatably installed on the output shaft of the drive motor.

[0008] There are two driven gears and two transmission rods. The two driven gears are located inside the housing, and the two transmission rods are fixedly installed on the inner sidewalls of the two driven gears respectively.

[0009] The coating assembly includes;

[0010] The coating cylinder and the lifting screw are both two in number. The two coating cylinders are fixedly installed side by side on the top wall of the receiving box, and the two lifting screws are threaded into the inside of the two transmission rods respectively.

[0011] The positioning rod and the positioning groove are provided. There are two positioning rods, which are fixedly installed on the bottom of the inner side wall of the two coating cylinders respectively. The positioning groove is opened on the side wall of the lifting screw.

[0012] There are two return pipes, which respectively send the excess pigment inside the two coating cylinders back to the inside of the receiving box.

[0013] The pump assembly includes;

[0014] The coating pump and the folded tube are two in total. The two coating pumps are fixedly installed on the bottom wall of the inner side of the housing, and the two folded tubes are fixedly installed on the output ends of the two coating pumps respectively.

[0015] The system includes two coating tanks located inside two lifting screws, and multiple spray holes for coating the bottom wall of the ship's iron outfitting components.

[0016] In some embodiments, the output shaft of the drive motor is fixedly mounted on the inner wall of the drive gear, two driven gears mesh with each other, and the top ends of the two transmission rods are rotatably mounted on the inner top wall of the housing via bearings.

[0017] In some embodiments, the two coating cylinders are respectively aligned with two driven gears, the positioning rod is slidably connected to a nearby positioning groove, the top ends of the two return pipes are respectively fixedly connected to the side walls of the two coating cylinders, and the bottom ends of the two return pipes are fixedly connected to the side walls of the receiving box.

[0018] In some embodiments, the two coating pumps are respectively aligned with two driven gears, the top ends of the two folded tubes are rotatably mounted on the bottom ends of the two coating tanks via bearings, the spray holes are evenly opened on the outer side walls of the two lifting screws, and the spray holes are connected to the interior of the coating tanks.

[0019] In some embodiments, there are two positioning components, each disposed inside one of the two coating cylinders. The positioning components include:

[0020] The positioning frame and the positioning bracket are fixedly installed on the top wall of the lifting screw and the positioning bracket is fixedly installed on the inner wall of the positioning frame.

[0021] Electromagnetic strips, of which there are multiple electromagnetic strips, are used to position the ship's iron outfitting components;

[0022] The device consists of a fixed block and a rolling ball. There are multiple fixed blocks, which are respectively fixedly installed on the top wall of multiple electromagnetic strips. The rolling ball is rotatably installed on the top of the fixed block.

[0023] In some embodiments, multiple electromagnetic strips are fixedly installed at equal intervals on the top wall of the positioning frame, the lines of the electromagnetic strips are located inside the lifting screw, and the top of the electromagnetic strips is serrated.

[0024] In some embodiments, the interior of the container is provided with an agitation assembly, which includes:

[0025] A fixing rod and multiple heating tubes are provided. The fixing rod is fixedly installed on the inner bottom wall of the receiving box, and the multiple heating tubes are fixedly installed at equal intervals on the side wall of the fixing rod.

[0026] Multiple agitator rods and multiple extension rods are used to agitate the pigment inside the container.

[0027] In some embodiments, the fixed rod is located between the two coating pumps, the multiple agitator rods are divided into two groups, the two groups of agitator rods are circumferentially fixedly installed on the bottom wall of the two driven gears, and the multiple extension rods are respectively circumferentially fixedly installed on the side wall of the multiple agitator rods.

[0028] In some embodiments, a shaking component is provided inside the coating cylinder, the shaking component including;

[0029] Multiple vibrating teeth one and multiple vibrating teeth two are respectively fixedly installed inside two positioning slots on the lifting screw;

[0030] The sliding groove, the push tooth, and the push spring are provided. The sliding groove is formed on the side wall of the positioning rod near the lifting screw. The push tooth is slidably installed inside the sliding groove, and the push spring is set inside the sliding groove.

[0031] In some embodiments, the first vibration tooth and the second vibration tooth are staggered, and the two ends of the push spring are fixedly connected to one side wall of the sliding groove and the push tooth, respectively.

[0032] The significant advantages of this invention compared to existing technologies are:

[0033] Firstly, this invention utilizes the magnetism of an electromagnetic strip to fix the ship's iron outfitting components. A drive assembly drives the driven gears to rotate. Since the two driven gears mesh with each other, their rotation directions are opposite. Therefore, the ship's iron outfitting components inside the two coating cylinders move in opposite directions. One coating cylinder performs the operation of adding and removing ship's iron outfitting components, while the other coating cylinder performs the coating operation on the ship's iron outfitting components. This achieves the effect of improving the coating efficiency of ship's iron outfitting components and solves the problem of low coating efficiency in existing ship's iron outfitting components.

[0034] Secondly, in this invention, the pigment inside the container is heated by a heating tube. Since the stirring rod is fixedly installed on the bottom wall of the driven gear, the stirring rod will rotate together with the driven gear. The stirring rod and the extension rod will thus stir the pigment inside the container, making the pigment flow and preventing the pigment from solidifying.

[0035] Thirdly, in this invention, when the lifting screw moves up and down with the rotation of the driven gear, the first and second vibrating teeth will sequentially contact the two sliding grooves, pushing the pushing teeth into the interior of the sliding grooves. Under the elastic influence of the pushing spring, the pushing teeth will strike the side wall of the lifting screw, causing the lifting screw to vibrate. Since the ship's iron outfitting parts are in contact with the side wall of the rolling ball, the ship's iron outfitting parts will slide on the top of the positioning frame due to vibration. The position of the ship's iron outfitting parts will thus shift, allowing the side wall of the ship's iron outfitting parts to fully contact the pigment inside the coating cylinder, avoiding insufficient coating at the bottom of the ship's iron outfitting parts due to the obstruction of the electromagnetic strip or the rolling ball.

[0046] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] This invention provides an improved anti-corrosion coating device for the surface of ship iron outfitting components. The technical solution of this invention is as follows:

[0048] like Figures 1-7As shown, a corrosion-resistant coating device for ship iron outfitting components includes a receiving box 1. The interior of the receiving box 1 is hollow. A drive assembly and a coating assembly extending into the interior of the receiving box 1 are arranged on the outside of the receiving box 1. A pump assembly is arranged inside the receiving box 1, and a positioning assembly is arranged on the outside of the receiving box 1. The drive assembly includes a fixed box 21, a drive motor 22, a drive gear 23, a driven gear 24, and a transmission rod 25. The fixed box 21 is fixedly installed on the outer wall of the receiving box 1, the drive motor 22 is fixedly installed on the top wall of the fixed box 21, and the drive gear 23 is rotatably mounted on the drive... There are two driven gears 24 on the output shaft of motor 22. Both driven gears 24 are located inside the housing 1 and mesh with each other. There are also two transmission rods 25, which are fixedly installed on the inner sidewalls of the two driven gears 24 respectively. The top ends of the two transmission rods 25 are rotatably mounted on the inner top wall of the housing 1 via bearings. By rotating the output end of the drive motor 22, the drive gear 23 can drive the two driven gears 24 to rotate. Since the two driven gears 24 mesh with each other, the rotation directions of the two driven gears 24 are opposite.

[0049] The coating assembly includes a coating cylinder 31, a lifting screw 32, a positioning rod 33, a positioning groove 34, and a return pipe 35. There are two coating cylinders 31, which are fixedly installed side by side on the top wall of the receiving box 1, and the two coating cylinders 31 are respectively aligned with two driven gears 24. There are two lifting screws 32, which are respectively set inside the two coating cylinders 31 and are respectively threaded inside the two transmission rods 25. There are two positioning rods 33, which are respectively fixedly installed evenly on the bottom of the inner side wall of the two coating cylinders 31. The positioning groove 34 is opened on the side wall of the lifting screw 32, and the positioning rod 33 is slidably connected to the adjacent positioning groove 34. There are two return pipes 35, which respectively send the excess pigment inside the two coating cylinders 31 back to the inside of the receiving box 1. The top ends of the two return pipes 35 are fixedly connected to the side walls of the two coating cylinders 31, and the bottom ends of the two return pipes 35 are fixedly connected to the side walls of the receiving box 1.

[0050] The pump assembly includes a coating pump 41, a folded tube 42, a coating tank 43, and spray holes 44. There are two coating pumps 41, which are fixedly installed on the bottom wall of the inner side of the receiving tank 1 and are respectively aligned with two driven gears 24. There are two folded tubes 42, which are used to transport the pigment inside the receiving tank 1 outward. The two folded tubes 42 are respectively fixedly installed on the output end of the two coating pumps 41. There are two coating tanks 43, which are respectively opened inside the two lifting screws 32. The top ends of the two folded tubes 42 are rotatably installed on the bottom end of the two coating tanks 43 through bearings. There are multiple spray holes 44, which are used to coat the bottom wall of the ship's iron outfitting parts. The multiple spray holes 44 are evenly opened on the outer side wall of the two lifting screws 32 and are connected to the inside of the coating tank 43.

[0051] There are two positioning components, each housed inside one of the two coating cylinders 31. Each positioning component includes a positioning frame 71, a positioning bracket 72, an electromagnetic strip 73, a fixing block 74, and a rolling ball 75. The positioning frame 71 is fixedly installed on the top wall of the lifting screw 32, and the positioning bracket 72 is fixedly installed on the inner wall of the positioning frame 71. Multiple electromagnetic strips 73 are equidistantly fixedly installed on the top wall of the positioning bracket 72. Each electromagnetic strip 73 is an electromagnet, and its wiring is located inside the lifting screw 32. The top of each electromagnetic strip 73 is serrated. Multiple fixing blocks 74 are fixedly installed on the top of each electromagnetic strip 73. The wall surface, the rolling ball 75 is rotatably mounted on the top of the fixed block 74; the ship iron outfitting is fixed by the magnetism of the electromagnetic strip 73, and the driven gear 24 is driven to rotate by the drive assembly. Since the two driven gears 24 mesh with each other, the rotation directions of the two driven gears 24 are opposite. Therefore, the ship iron outfitting inside the two coating cylinders 31 moves in opposite directions. The ship iron outfitting moves downward with the lifting screw 32, so that the pigment inside the coating cylinder 31 is coated on the surface of the ship iron outfitting. The coated ship iron outfitting moves upward with the lifting screw 32 and extends out of the interior of the coating cylinder 31. By de-energizing the electromagnetic strip 73, the coated ship iron outfitting can be easily taken out.

[0052] like Figures 1-4As shown, in one embodiment, to ensure the fluidity of the pigment, a stirring assembly is provided inside the container 1. The stirring assembly includes a fixed rod 51, heating tubes 52, stirring rods 53, and an extension rod 54. The fixed rod 51 is fixedly installed on the inner bottom wall of the container 1, positioned between the two coating pumps 41. There are multiple heating tubes 52, which are equidistantly fixed on the side wall of the fixed rod 51. There are multiple stirring rods 53, which are divided into two groups, with the two groups of stirring rods 53 having equal circumference. Multiple extension rods 54 are fixedly installed on the bottom wall of two driven gears 24, and are equidistantly fixedly installed on the side wall of multiple stirring rods 53. The pigment inside the container 1 is heated by the heating tube 52. Since the stirring rods 53 are fixedly installed on the bottom wall of the driven gears 24, the stirring rods 53 will rotate together with the driven gears 24. The stirring rods 53 and the extension rods 54 will thus stir the pigment inside the container 1, making the pigment flow and preventing the pigment from solidifying.

[0053] like Figures 1-7 As shown, in one embodiment, to ensure that the bottom wall of the ship's iron outfitting components can be fully coated, a vibration assembly is provided inside the coating cylinder 31. The vibration assembly includes a vibration tooth 61, a vibration tooth 62, a sliding groove 63, a pushing tooth 64, and a pushing spring 65. There are multiple vibration teeth 61 and 62. The multiple vibration teeth 61 and 62 are respectively fixedly installed inside the two positioning grooves 34 on the lifting screw 32. The vibration teeth 61 and 62 are staggered. The sliding groove 63 is opened on the side wall of the positioning rod 33 near the lifting screw 32. The pushing tooth 64 is slidably installed inside the sliding groove 63. The pushing spring 65 is disposed inside the sliding groove 63, and the two ends of the pushing spring 65 are respectively connected to the sliding groove 63. The lifting screw 32 is fixedly connected to one side wall of the push tooth 64. When the lifting screw 32 moves up and down with the rotation of the driven gear 24, the first vibration tooth 61 and the second vibration tooth 62 will contact the two sliding grooves 63 in sequence, pushing the push tooth 64 into the interior of the sliding groove 63. Under the elastic influence of the push spring 65, the push tooth 64 will hit the side wall of the lifting screw 32, causing the lifting screw 32 to vibrate. Since the ship iron outfitting is in contact with the side wall of the rolling ball 75, the ship iron outfitting will slide on the top of the positioning frame 71 due to vibration. The position of the ship iron outfitting will thus shift, so that the side wall of the ship iron outfitting can fully contact the pigment inside the coating cylinder 31, avoiding the situation where the bottom of the ship iron outfitting is not fully coated due to the obstruction of the electromagnetic strip 73 or the rolling ball 75.

[0054] The specific working method is as follows: The ship's iron outfitting components are fixed using the magnetism of the electromagnetic strip 73. The rotation of the output end of the drive motor 22 causes the drive gear 23 to drive two driven gears 24 to rotate. Since the two driven gears 24 mesh with each other, their rotation directions are opposite. Therefore, the ship's iron outfitting components inside the two coating cylinders 31 move in opposite directions. The ship's iron outfitting components move downwards with the lifting screw 32, and the pigment inside the receiving box 1 is sent into the coating cylinder by the coating pump 41. Inside the coating tank 43, pigment is sprayed onto the bottom wall of the ship's iron outfitting parts through the spray holes 44, so that the pigment inside the coating cylinder 31 is coated onto the surface of the ship's iron outfitting parts. After coating, the ship's iron outfitting parts move upward with the lifting screw 32 and extend out of the coating cylinder 31. By de-energizing the electromagnetic strip 73, the coated ship's iron outfitting parts can be easily removed. Excess pigment inside the coating cylinder 31 is returned to the receiving box 1 through the return pipe 35. The pigment inside the receiving box 1 is heated by the heating pipe 52. Heating occurs because the stirring rod 53 is fixedly installed on the bottom wall of the driven gear 24, so the stirring rod 53 rotates together with the driven gear 24. The stirring rod 53 and the extension rod 54 thus stir the pigment inside the container 1, causing the pigment to flow and preventing it from solidifying. When the lifting screw 32 moves up and down with the rotation of the driven gear 24, the first vibrating tooth 61 and the second vibrating tooth 62 sequentially contact the two sliding grooves 63, pushing the pushing tooth 64 into the interior of the sliding groove 63. Under the elastic influence of the push spring 65, the push tooth 64 strikes the side wall of the lifting screw 32, causing the lifting screw 32 to vibrate. Since the ship's iron outfitting part is in contact with the side wall of the rolling ball 75, the ship's iron outfitting part will slide on the top of the positioning frame 71 due to the vibration. The position of the ship's iron outfitting part is thus offset, so that the side wall of the ship's iron outfitting part can fully contact the pigment inside the coating cylinder 31, avoiding the situation where the bottom of the ship's iron outfitting part is not fully coated due to the obstruction of the electromagnetic strip 73 or the rolling ball 75.
