Description

Technical Field

[0002] In the current steel pipe pole processing technology field, it is necessary to perform zinc spraying on the surface of the steel pipe pole. The principle of thermal zinc spraying can be summarized as follows: first, high-pressure air and pipelines are used to blow sand particles onto the surface of the workpiece to remove rust and oxide scale from the metal surface, while simultaneously roughening the surface to increase the adhesion of the thermal spray coating. Then, using oxygen, acetylene or electric heating source, compressed air and special tools (spray gun) are used to atomize zinc and spray it onto the metal surface at ultra-high speed to protect the surface of the steel pipe pole.

This machine adjusts the height of the zinc spraying device to reduce zinc powder waste, save costs, improve the uniformity of zinc spraying on pipe fittings, enhance the spraying effect, increase work efficiency, and improve environmental friendliness. The machine includes a base plate, a zinc spraying device, and a fixing device. The fixing device is installed at the top of the base plate, and the zinc spraying device is installed at the top of the fixing device. It also includes an adjustment device, a drive device, an air purification device, and a support device. The adjustment device includes four second hydraulic cylinders, four mounting blocks, a screw, a rotating motor, a moving block, a slide bar, a slider, and a connecting rod. The adjustment device is installed at the top of the fixing device, the zinc spraying device is installed on the adjustment device, the drive device is installed on the fixing device, the air purification device is installed at the top of the adjustment device, and the support device is installed at the bottom of the base plate.

[0004] The aforementioned patent has the following shortcomings:

[0005] The aforementioned patent uses a fixed center and a moving center to fix the steel pipe and drive it to rotate, thereby spraying zinc during rotation and saving raw materials. However, the distance between the fixed center and the moving center is limited, and it can only fix general-purpose steel pipes of a certain type, which limits its application range. In addition, it cannot transport steel pipes, and the steel pipes need to be installed manually on the fixed center and the moving center, resulting in low installation efficiency and thus reducing the zinc spraying efficiency of the steel pipes.

[0037] Please see Figure 1-3This utility model provides a technical solution: a zinc spraying device for corrosion protection of steel pipe poles, including a support mechanism 1, the support mechanism 1 including a support frame 12 and a rotating mechanism 2, which is installed on the support mechanism 1. The rotating mechanism 2 includes hydraulic push rods 21. Two hydraulic push rods 21 are fixedly installed on the outer walls of both sides of the support frame 12. The telescopic end of the hydraulic push rod 21 passes through the outer wall of the support frame 12 and is fixedly installed with a fixing frame 211. The fixing frame 211 is rotatably installed with a rotating shaft 22 through a bearing. Two rotating shafts 22 are rotatably installed on the corresponding fixing frames 211. A gear 221 is fixedly installed at the end of the rotating shaft 22. A gear 24 is fixedly installed on the fixing frame 211. A gear 241 that meshes with the gear 221 is fixedly installed at the output end of the gear 24. Two support wheels 23 are fixedly installed on the outer wall of the rotating shaft 22.

[0038] The hydraulic push rod 21 extends and retracts through its telescopic end, causing the fixed frame 211 to move laterally, thereby adjusting the distance between the two rotating shafts 22. This is suitable for steel pipes of different diameters. Multiple support wheels 23 are arranged in an alternating pattern to facilitate support of the steel pipes. This is suitable for steel pipes of different lengths. The geared motor 24 drives the rotating shaft 22 to rotate through gear transmission, thereby using the support wheels 23 to drive the steel pipe to rotate, which facilitates zinc spraying on the surface of the steel pipe.

[0039] Two electric push rods 25 are fixedly installed on the support platform 111. A U-shaped lifting frame 251 is fixedly installed on the telescopic end of each of the two electric push rods 25. A conveying roller 26 is rotatably installed on the lifting frame 251. The two conveying rollers 26 are located at both ends of the rotating shaft 22. A second geared motor 261 is fixedly installed on the outer wall of the lifting frame 251. The second geared motor 261 is connected to the conveying roller 26.

[0040] The electric push rod 25 extends and retracts, driving the lifting frame 251 to move longitudinally, which in turn causes the conveying roller 26 to support the steel pipe. The reduction motor 261 drives the conveying roller 26 to rotate, thereby using the conveying roller 26 to transport the steel pipe, resulting in higher loading and unloading efficiency.

[0041] The zinc spraying mechanism 3 is used for spraying zinc. The zinc spraying mechanism 3 is installed on the support mechanism 1. The protective box 13 is fixedly installed on the support frame 12. The drive screw 31 is rotatably installed on the top wall inside the protective box 13. The drive screw 31 is threadedly connected to the sliding nut 311. The drive motor 312 is fixedly installed on the outer wall of the protective box 13. The drive motor 312 is connected to the drive screw 31. The lower end of the sliding nut 311 is fixedly installed with a pneumatic push rod 32. The telescopic end of the pneumatic push rod 32 is fixedly installed with a nozzle 331. The zinc spraying machine 33 is fixedly installed on the outer wall of the support frame 12. The zinc spraying machine 33 is connected to the nozzle 331 through a hose.

[0042] Furthermore, the protective box 13 can prevent raw materials from splashing during zinc spraying. At the same time, a transparent window can be installed on the outer wall of the protective box 13 to facilitate observation of the steel pipe during zinc spraying. The zinc spraying machine 33 uses the nozzle 331 to spray zinc. The drive motor 312 drives the drive screw 31 to rotate, thereby causing the sliding screw nut 311 to move laterally, which in turn drives the nozzle 331 to move laterally, resulting in more uniform spraying. The pneumatic push rod 32 drives the nozzle 331 to move longitudinally, bringing the nozzle 331 closer to the steel pipe, reducing splashed raw materials and saving operating costs.

[0043] A support leg 11 is fixedly installed at the lower end of the support frame 12, a support platform 111 is fixedly installed on the support leg 11, and a waste bin 14 is fixedly installed on the support platform 111.

[0044] Specifically, the waste bin 14 is used to collect the waste generated during zinc spraying, making it easier to process in a centralized manner.

[0045] The working principle and usage process of this utility model are as follows: Please refer to... Figure 1-3 The electric push rod 25, through its telescopic extension and retraction, drives the lifting frame 251 to move longitudinally, thereby enabling the conveying roller 26 to support the steel pipe. The second reduction motor 261 drives the conveying roller 26 to rotate, thus using the conveying roller 26 to transport the steel pipe, allowing the steel pipe to slide onto multiple support wheels 23. The hydraulic push rod 21, through its telescopic extension and retraction, drives the fixed frame 211 to move laterally, thereby adjusting the distance between the two rotating shafts 22. This is suitable for steel pipes of different diameters, and the multiple support wheels 23 are arranged in an alternating pattern to facilitate the support of the steel pipe, making it suitable for steel pipes of different lengths. The first reduction motor 24 drives the rotating shaft 22 to rotate through gear transmission, thereby using the support wheels 23 to drive the steel pipe to rotate. The zinc spraying machine 33 uses the nozzle 331 to spray zinc. The drive motor 312 drives the drive screw 31 to rotate, thereby causing the sliding screw nut 311 to move laterally, which in turn drives the nozzle 331 to move laterally, resulting in more uniform spraying. The pneumatic push rod 32 drives the nozzle 331 to move longitudinally, bringing the nozzle 331 closer to the steel pipe, reducing splashing of raw materials and lowering operating costs.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
