Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion coating spraying technology for steel structures, and in particular to a rapid treatment device for anti-corrosion coatings on ship steel structures. Background Technology

[0002] The anti-corrosion coating of ship steel structures is usually a multi-layer coating system designed to prevent steel from rusting due to environmental factors such as seawater, salt spray, and humid air.

[0003] Currently, the spraying of anti-corrosion coatings for ship steel structures generally relies on manual spraying by operators holding spray guns. Because manual operation makes it difficult to maintain a stable moving speed and spraying angle, it easily leads to uneven coating thickness on the steel structure surface, affecting not only the anti-corrosion effect but also potentially wasting materials. Furthermore, traditional spraying methods require a high level of operator skill; novices need extensive training to master the technique of uniform spraying, which increases training costs and reduces operational efficiency. Therefore, this paper proposes a rapid processing device for anti-corrosion coatings on ship steel structures to overcome these shortcomings. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid treatment device for anti-corrosion coatings on ship steel structures.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rapid anti-corrosion coating treatment device for ship steel structures, comprising a placement platform and a steel structure body. A tank is fixedly connected to the top of the placement platform, a high-pressure pump is fixedly connected to the top of the tank, a feed pipe is fixedly connected to the output end of the high-pressure pump, a spray gun is fixedly connected to the end of the feed pipe away from the high-pressure pump, a multi-hole nozzle is fixedly connected to the output end of the spray gun, a clamping plate is slidably connected to the outside of the spray gun, handles are fixedly connected to the top left and right sides of the clamping plate, tension springs are fixedly connected to the left and right sides of the middle of the inside of the clamping plate, a clamping plate is fixedly connected to the top of the outer side of the tension spring, a fixed shaft is fixedly connected to the upper inside of the clamping plate, a sliding wheel is rotatably connected to the outside of the fixed shaft, rollers are provided at the four corners of the bottom of the placement platform, a linkage shaft is fixedly connected between the rollers on the left and right sides of the front side of the bottom of the placement platform, a driven wheel is fixedly connected to the outer side of the middle of the linkage shaft, a motor is fixedly connected to the middle of the left side of the bottom of the placement platform, a driving wheel is fixedly connected to the output end of the motor, and a belt is provided between the driving wheel and the driven wheel.

[0006] As a further description of the above technical solution: the left and right sides inside the card plate are slidably connected to the outer side of the clamping plate near the tension spring, and the left and right ends of the steel structure body are in contact with the inner side of the sliding wheel, so that the spray gun fixed inside the card plate can spray from top to bottom onto the surface of the steel structure body. The clamping plate is used to clamp the left and right sides of the steel structure body. With the cooperation of the fixed shaft and sliding wheel set inside the clamping plate, the operator can hold the handle and push the card plate and clamping plate at a uniform speed, so that the spray gun can spray evenly along the steel structure.

[0007] As a further description of the above technical solution: the output end of the high-pressure pump is provided with a material extraction pipe, and the bottom end of the material extraction pipe is located at the lower part of the tank. The nozzles of the multi-hole nozzles at the output end of the spray gun are arranged from left to right, which allows the high-pressure pump to extract the anti-corrosion coating from the tank and spray it out from the spray gun. The multi-hole nozzles can increase the spray range of the anti-corrosion coating.

[0008] As a further description of the above technical solution: the card plate has grooves on the left and right sides inside, and the longitudinal cross-sectional shape of the grooves on the left and right sides inside the card plate matches the cross-sectional shape of the top inner side of the clamping plate. The overall shape of the clamping plate is L-shaped, so that the clamping plate has tension and it is convenient for the card plate to be placed above the steel structure body.

[0009] As a further description of the above technical solution: the tension spring is located in the grooves on the left and right sides inside the card plate, and the tension spring provides a spring force F of 7N and a spring constant k of 35N / m, which effectively avoids the situation where the thickness of the anti-corrosion coating is uneven due to the operator's technical problems when spraying the anti-corrosion coating on the steel structure body with a spray gun, and improves the uniformity of the anti-corrosion coating sprayed on the steel structure body by the spray gun to a certain extent.

[0010] As a further description of the above technical solution: there are two sets of sliding wheels on the outside of the fixed shaft, and the sliding wheels are distributed on the upper and lower sides of the outside of the fixed shaft. A groove is opened in the upper part of the clamping plate, and the longitudinal cross-sectional shape of the groove is consistent with the overall longitudinal cross-sectional shape of the fixed shaft plus the sliding wheels. This can reduce the technical difficulty for operators to spray anti-corrosion coating on the steel structure body with a spray gun, and it is simple to learn and easy to operate.

[0011] As a further description of the above technical solution: the active wheel and the passive wheel are in a parallel position, and the longitudinal cross-sectional shape of the roller and the passive wheel is "I" shaped, which can achieve the purpose of the roller at the bottom top of the placement platform rotating with the motor, so that the placement platform can drive the tank to move with the operator.

[0012] This utility model has the following beneficial effects:

[0013] This utility model designs a rapid anti-corrosion coating treatment device for ship steel structures. Through the design and cooperation of tension springs and clamping plates, the device allows the spray gun, fixed inside the clamping plate, to spray the coating onto the surface of the steel structure from top to bottom. The clamping plate is used to hold the left and right sides of the steel structure. With the cooperation of the fixed shaft and sliding wheels set inside the clamping plate, the operator can hold the handle and push the clamping plate at a uniform speed, allowing the spray gun to spray evenly along the steel structure. This effectively avoids the problem of uneven coating thickness caused by the operator's technical problems when spraying the anti-corrosion coating onto the steel structure. It improves the uniformity of the anti-corrosion coating sprayed onto the steel structure to a certain extent, and reduces the technical difficulty for the operator to use the spray gun to spray the anti-corrosion coating onto the steel structure. It is simple to use and easy to operate. In addition, a motor is set at the bottom of the placement platform. The motor drives the drive wheel at the output end and the belt connecting the driven wheel to rotate synchronously. This allows the roller at the bottom of the placement platform to rotate with the motor, so that the placement platform and the tank can move with the operator. Attached Figure Description

[0020] Reference Figures 1 to 4This utility model provides a rapid anti-corrosion coating treatment device for ship steel structures, including a placement platform 1 and a steel structure body 10. A tank 2 is installed on the top of the placement platform 1, and a high-pressure pump 3 is fixed to the top of the tank 2 by bolts. The output end of the high-pressure pump 3 is connected to a feed pipe 4 through a flange. A spray gun 5 is installed at the end of the feed pipe 4 away from the high-pressure pump 3. A multi-hole nozzle 6 is installed at the output end of the spray gun 5. A clamping plate 7 is passed through the outside of the spray gun 5 and fixed by bolts. Handles 11 are welded to the left and right sides of the top of the clamping plate 7, and tension springs 12 are welded to the left and right sides of the middle of the inside of the clamping plate 7. A clamping plate 8 is welded to the top of the outer side of the extension spring 12. The clamping plate 8 is inserted and fixed by a fixed shaft 13. The outer side of the fixed shaft 13 is connected to a sliding wheel 9 through a bearing. Rollers 14 are set at the four corners of the bottom of the platform 1. A linkage shaft 15 is welded between the rollers 14 on the left and right sides of the bottom of the platform 1. A driven wheel 16 is welded to the outer side of the middle of the linkage shaft 15. A motor 17 is fixed to the middle of the left side of the bottom of the platform 1 with bolts. The output shaft of the motor 17 is welded to the middle of the left end face of the drive wheel 18. A belt 19 is set between the drive wheel 18 and the driven wheel 16.

[0021] The left and right sides of the inside of the clamping plate 7 are slidably connected to the outer side of the clamping plate 8 near the tension spring 12. The left and right ends of the steel structure body 10 are in contact with the inner side of the sliding wheel 9, allowing the spray gun 5 fixed inside the clamping plate 7 to spray from top to bottom onto the surface of the steel structure body 10. The clamping plate 8 is used to clamp the left and right sides of the steel structure body 10. With the fixed shaft 13 and sliding wheel 9 set inside the clamping plate 8, the operator can hold the handle 11 and push the clamping plate 7 and the clamping plate 8 at a uniform speed, so that the spray gun 5 can spray evenly along the steel structure.

[0022] As a further implementation of the above technical solution: the output end of the high-pressure pump 3 is equipped with a suction pipe, and the bottom end of the suction pipe is located at the lower part of the tank body 2. The nozzles of the multi-hole nozzle 6 at the output end of the spray gun 5 are arranged from left to right, which allows the high-pressure pump 3 to extract the anti-corrosion coating from the tank body 2 and spray it out from the spray gun 5. The setting of the multi-hole nozzle 6 can increase the spray range of the anti-corrosion coating.

[0023] As a further implementation of the above technical solution: the inside of the card plate 7 has grooves on the left and right sides from the inside out, and the longitudinal cross-sectional shape of the grooves on the left and right sides of the card plate 7 matches the cross-sectional shape of the top inner side of the clamping plate 8. The overall shape of the clamping plate 8 is L-shaped, so that the clamping plate 8 has tension, making it convenient for the card plate 7 to be placed above the steel structure body 10.

[0024] As a further implementation of the above technical solution: the tension spring 12 is located in the grooves on the left and right sides inside the card plate 7, and the elastic force F provided by the tension spring 12 is 7N, and the stiffness coefficient k is 35N / m. This effectively avoids the situation where the thickness of the anti-corrosion coating is uneven due to the operator's technical problems when the spray gun 5 is used to spray the anti-corrosion coating on the steel structure body 10, and improves the uniformity of the anti-corrosion coating sprayed by the spray gun 5 on the steel structure body 10 to a certain extent.

[0025] As a further implementation of the above technical solution: there are two sets of sliding wheels 9 on the outside of the fixed shaft 13, and the sliding wheels 9 are distributed on the upper and lower sides of the outside of the fixed shaft 13. A groove is opened in the upper part of the clamping plate 8, and the longitudinal cross-sectional shape of the groove is consistent with the overall longitudinal cross-sectional shape of the fixed shaft 13 plus the sliding wheels 9. This can reduce the technical difficulty for operators to spray anti-corrosion coating on the steel structure body 10 with the spray gun 5, and is simple to learn and easy to operate.

[0026] As a further implementation of the above technical solution: the active wheel 18 and the passive wheel 16 are in a parallel position, and the longitudinal cross-sectional shape of the roller 14 and the passive wheel 16 is "I" shaped, so that the roller 14 at the bottom top of the placement platform 1 can rotate with the motor 17, allowing the placement platform 1 to drive the tank 2 to move with the operator.

[0027] Working principle:

[0028] When using this invention, the anti-corrosion coating is injected into the tank 2. Then, the clamping plate 7 is placed on the outside of the spray gun 5 from top to bottom and fixed with bolts. The spray gun 5 can then be flipped over and inserted from top to bottom directly above the steel structure body 10. At this time, the clamping plate 8 is squeezed and slides outward along the inside of the clamping plate 7. The tension spring 12 deforms. At this time, the sliding wheel 9 on the outside of the fixed shaft 13 inside the clamping plate 8 also contacts the left and right end faces of the steel structure body 10. At this time, the spray gun 5 is restricted to the top of the steel structure body 10. Then, the large motor 17 at the bottom of the placement platform 1 is started. The motor 17 drives the drive wheel 18 at the output end to rotate. The drive wheel 18 is equipped with a belt 19 connected to the driven wheel 16. Therefore, the driven wheel 16 drives the linkage shaft 15 and the rollers 14 at the top of the left and right sides of the linkage shaft 15 to follow the drive wheel 18. The tank 2 rotates synchronously, and is moved by the placement platform 1. The high-pressure pump 3 on the top of the tank 2 is turned on, and the high-pressure pump 3 extracts the anti-corrosion coating from the tank 2 and delivers it to the spray gun 5 through the conveying pipe 4. The anti-corrosion coating is then sprayed onto the upper surface of the steel structure body 10 through the multi-hole nozzle 6. The operator follows the movement of the placement platform 1, holds the handles 11 on the left and right sides of the top of the clamping plate 7 and pushes the spray gun 5. The spray gun 5 sprays evenly along the steel structure, effectively avoiding the situation where the thickness of the anti-corrosion coating is uneven due to the operator's technical problems when using the spray gun 5 to spray the anti-corrosion coating on the steel structure body 10. This improves the uniformity of the anti-corrosion coating sprayed on the steel structure body 10 by the spray gun 5 to a certain extent, and at the same time reduces the technical difficulty for the operator to use the spray gun 5 to spray the anti-corrosion coating on the steel structure body 10. It is simple and easy to operate.
