[0002] Galvanized steel pipes offer strong corrosion resistance and a long service life. They are widely used, not only as line pipe for conveying low-pressure fluids such as water, gas, and oil, but also for oil well pipes and pipelines in the petroleum industry, particularly offshore oil fields; for oil heaters, condenser coolers, and coal distillation and washing oil exchangers in chemical coking equipment; and for pier piles and support frames in mine tunnels. Hot-dip galvanized steel pipes are widely used in fire protection, power generation, and highway applications.

[0025] See also Figure 1-6 The utility model provides a technical solution: a galvanized steel pipe weld spraying device, comprising a frame 1 and a steel pipe body 7, drive platforms 2 are provided on both sides of the front end of the frame 1, the steel pipe body 7 is placed on two groups of drive platforms 2, a top plate 3 is provided on the top of the frame 1, a spraying assembly 4 and a suction assembly 5 are provided on the top plate 3, the drive platform 2 includes a frame body 21, a first drive roller 22 and a second drive roller 23 are provided on the frame body 21, the first drive roller 22 and the second drive roller 23 are driven by a motor 27, the spraying assembly 4 includes a spray gun 46, the suction assembly 5 includes two groups of suction hoppers 56, and the two groups of suction hoppers 56 are distributed on both sides of the spray gun 46.

[0026] When placing the steel pipe body 7, the two ends of the steel pipe body 7 are respectively mounted on the driving platforms 2 on both sides, and the weld position of the steel pipe body 7 is moved to just below the spray gun 46. The steel pipe body 7 is automatically placed between the first driving roller 22 and the second driving roller 23 under the action of its own gravity. Figure 6 As shown, a group of motors 27 drive the first drive roller 22 and the second drive roller 23 to rotate in the same direction. When the first drive roller 22 and the second drive roller 23 rotate in the same direction, the steel pipe body 7 on the upper part thereof is driven to rotate. By driving the steel pipe body 7 to rotate, the weld position of the steel pipe body 7 is rotated synchronously.

[0027] Among them, the weld position of the steel pipe main body 7 is sprayed by the spray gun 46 of the spray assembly 4, and the paint is sprayed onto the weld surface. During the continuous spraying process of the spray gun 46, the weld position of the steel pipe main body 7 rotates at a uniform speed. Without changing the position of the spray gun 46, a comprehensive spraying operation is achieved on the weld position of the steel pipe main body 7.

[0028] Among them, the two groups of suction hoppers 56 generate negative pressure adsorption force during the spraying process, absorbing the paint diffused into the air from the spraying position to prevent the paint from further spreading. The polluted air and excess paint are concentrated into the two groups of suction hoppers 56 and collected and filtered by the suction component 5 to ensure the cleanliness of the spraying environment.

[0029] Among them, one end of the first driving roller 22 is connected to the driving wheel 24, one end of the second driving roller 23 is connected to the driven wheel 25, the driven wheel 25 and the driving wheel 24 are driven by a synchronous belt 26, the output shaft of the motor 27 is connected to the reducer, and the output shaft of the reducer is connected to the driving wheel 24.

[0030] Among them, when the motor 27 is working, it drives the driving wheel 24 to rotate through the reducer, and the driving wheel 24 drives the driven wheel 25 to rotate through the synchronous belt 26. The driving wheel 24 drives the first driving roller 22 to rotate, and the driven wheel 25 drives the second driving roller 23 to rotate. Under the drive of the motor 27, the first driving roller 22 and the second driving roller 23 rotate in the same direction.

[0031] The spray assembly 4 includes a paint storage tank 41 , a pump body 42 is provided at the upper end of the paint storage tank 41 , the pump body 42 is connected to a delivery pipe 43 , and one end of the delivery pipe 43 is connected to a spray gun 46 .

[0032] Among them, the paint required for spraying is pre-stored in the paint storage tank 41. When the pump body 42 is working, the paint inside the paint storage tank 41 is extracted and sent to the delivery pipe 43. The paint enters the spray gun 46 through the delivery pipe 43 and is finally sprayed out through the spray gun 46 for spraying, spraying the paint onto the weld surface of the steel pipe body 7.

[0033] A feeding port 44 is provided on one side of the upper end of the paint storage tank 41 , and a viewing window 45 is provided on the side of the paint storage tank 41 , through which the paint level can be observed. When the paint is insufficient, the paint can be distributed through the feeding port 44 .

[0034] Among them, the suction component 5 includes a filter box 51, and a filter cartridge 52 is arranged inside the filter box 51. One end of the filter cartridge 52 is connected to the exhaust fan 53, and the exhaust fan 53 is the power source for the two sets of suction buckets 56 to generate negative pressure suction force.

[0035] Among them, a cover plate 57 is provided at the top of the filter box 51, and the cover plate 57 and the filter box 51 are fixedly connected by a slot. The cover plate 57 can be opened and closed, and the filter cartridge 52 inside the filter box 51 can be cleaned and replaced by manually opening the cover plate 57.

[0036] An exhaust pipe 54 is provided on the cover plate 57 , one end of the exhaust pipe 54 is connected to an air suction pipe 55 , and the air suction pipe 55 is connected to two sets of air suction hoppers 56 .

[0037] Among them, when the exhaust fan 53 is working, a negative pressure suction force is generated inside the filter box 51, so that the exhaust pipe 54, the intake pipe 55 and the two sets of suction buckets 56 synchronously generate a negative pressure suction force. When the weld of the steel pipe body 7 is sprayed, the surrounding polluted air and excess paint are absorbed by the negative pressure suction force to ensure the cleanliness of the spraying environment. The sucked air enters the filter box 51, is filtered by the filter cartridge 52, and is then discharged.

[0038] Among them, a collection platform 6 is provided at the front end of the frame 1, and the collection platform 6 is located below the driving platform 2. The collection platform 6 is used to collect paint particles with larger weight to prevent the paint from falling to the ground, thereby preventing the ground from being polluted.

[0039] The steel pipe body 7 includes a weld, and the weld is located directly below the spray gun 46 . When placing the steel pipe body 7 , the weld of the steel pipe body 7 is moved directly below the spray gun 46 .

A set of motors 27 drives the first driving roller 22 and the second driving roller 23 to rotate in the same direction. When the first driving roller 22 and the second driving roller 23 rotate in the same direction, the steel pipe body 7 on the upper part thereof is driven to rotate, and the exhaust fan 53 works to generate a negative pressure suction force inside the filter box 51, thereby causing the exhaust pipe 54, the suction pipe 55 and the two sets of suction buckets 56 to generate a negative pressure suction force synchronously, and the pump body 42 works to extract the paint inside the paint storage tank 41 and spread the paint. The material is delivered to the delivery pipe 43, enters the spray gun 46 through the delivery pipe 43, and is finally sprayed out by the spray gun 46 for spraying, and the paint is sprayed onto the weld surface of the steel pipe body 7. During the continuous spraying process of the spray gun 46, the weld position of the steel pipe body 7 rotates at a uniform speed. Without changing the position of the spray gun 46, a comprehensive spraying operation is achieved on the weld position of the steel pipe body 7. The negative pressure suction force of the two sets of suction buckets 56 absorbs the surrounding polluted air and excess paint to ensure the cleanliness of the spraying environment. The sucked air enters the filter box 51, is filtered by the filter cartridge 52 and then discharged, and the paint particles with larger weight fall to the collection table 6.
