Abstract
Description
Technical Field
[0001] This application relates to the field of welding material processing, and more specifically, to a surface treatment device for welding materials for offshore platforms. Background Technology
[0002] Offshore platforms operate in extremely harsh environments, constantly subjected to seawater corrosion, salt spray erosion, and marine organism attachment. Therefore, the welding materials used in offshore platforms require extremely high standards; their surfaces must possess excellent corrosion resistance, resistance to marine organism attachment, and sufficient strength and toughness.
[0003] Patent document CN208840661U discloses a moving device for surface treatment of target brazing, including a limiting guide rail detachably fixed to a worktable; several rollers, at least one pair, movably mounted on the limiting guide rail; and a moving platform connected to the rollers to reciprocate along the guide rail. An ultrasonic processor is fixed to the bottom of the moving platform, used to wet the target brazing surface.
[0004] While the aforementioned application documents greatly save the operator's effort and provide more uniform local treatment of the target material's brazing surface, thus significantly improving work efficiency, welding slag may splatter during welding, causing injury to workers.
[0005] Therefore, we provide a surface treatment device for welding materials for offshore platforms. Utility Model Content

A paint spraying pipe is fixedly connected to the right side of the peristaltic pump body.
[0012] Preferably, the outer wall of the collar and the outer wall of the output end of the peristaltic pump body are connected by a belt pulley.
[0013] The advantages of this application are:
[0014] 1. This application moves the mobile device to the welding position by pushing the handle, and the hydraulic cylinder drives the grinder to descend for grinding. At the same time, the rack drives the circular gear to rotate, causing the protective door to rotate counterclockwise to block the grinding position, preventing debris from flying and injuring people, thus achieving simultaneous safety protection and grinding.
[0015] 2. When the lever rotates clockwise, the ratchet and pawl work together to drive the collar and pulley to rotate, thereby driving the peristaltic pump to draw paint from the paint tank and spray paint onto the ground area through the paint spray pipe, thereby improving the corrosion resistance of the welding material.

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.

[0025] Example 1
[0026] See Figure 1 - Figure 4 This embodiment provides a surface treatment device for welding materials on offshore platforms, including a base 1. A protective device 2 is mounted on the top of the base 1. The protective device 2 includes a hydraulic cylinder 21, which is fixedly connected to the top of the base 1. A connecting rod 22 is fixedly connected to the bottom of the output end of the hydraulic cylinder 21. A grinding machine body 4 is fixedly connected to the bottom of the connecting rod 22. A rack 23 is fixedly connected to the right side of the connecting rod 22. A rotating rod 24 is rotatably connected to the front of the base 1 via a bearing. A circular gear 25 is fixedly connected to the outer wall of the rotating rod 24. A protective door 26 is fixedly connected to the front of the rotating rod 24. A protective plate 28 is fixedly connected to the right side of the base 1. A handle 27 is fixedly connected to the side of the protective plate 28. A caster 5 is fixedly connected to the bottom of the base 1. Gear 25 meshes with rack 23. The top of base 1 has a receiving groove for accommodating gear 25 and rack 23. The lifting and lowering of the grinding machine body 4 is controlled by hydraulic cylinder 21 and connecting rod 22, which can precisely control the grinding depth. The connecting rod 22 drives rack 23 to descend, and rack 23 drives gear 25 to rotate. Then, the rotating rod 24 achieves precise control of the grinding machine. The protective door 26 closes as the rotating rod 24 rotates, avoiding the splashing of debris during the grinding process, thus ensuring the safety of the workers. The grinding machine body 4 grinds the surface of the welding material, removes irregular surfaces, welding residues or rust, improves the smoothness and adhesion of the welded parts, and lays a good foundation for subsequent anti-corrosion treatment.
[0027] In practical use, the above equipment is moved by pushing handle 27 to move base 1 and moving wheel 5 to the position where grinding is required after welding. Hydraulic cylinder 21 is started, and the output end of hydraulic cylinder 21 drives connecting rod 22 to descend. Connecting rod 22 drives grinding machine body 4 to descend. At the same time as connecting rod 22 descends, rack 23 descends. Rack 23 drives spur gear 25 to rotate. Spur gear 25 drives rotating rod 24 to rotate. Rotating rod 24 drives protective door 26 to rotate counterclockwise to block the grinding position and prevent the debris generated during grinding from flying and causing injury to the workers. The surface of the welding material is ground by grinding machine body 4.
[0028] Example 2
[0029] See Figure 1 - Figure 4 Based on Embodiment 1, a spraying device 3 for spraying anti-corrosion primer is installed on the top of the base 1. The spraying device 3 includes a ratchet 31, which is fixedly sleeved on the outer wall of the rotating rod 24. A collar 33 is rotatably connected to the back of the receiving groove through a bearing. A pawl 32 is hinged to the inner wall of the collar 33. A paint tank 36 is fixedly connected to the top of the base 1. A suction tube 37 is fixedly connected to the bottom of the paint tank 36. A peristaltic pump body 35 is fixedly connected to the bottom of the base 1. A paint spraying tube 38 is fixedly connected to the right side of the peristaltic pump body 35. The outer wall of the collar 33 and the outer wall of the output end of the peristaltic pump body 35 are connected by a pulley 34. The spraying device 3 drives the ratchet 31 and the pawl 32 through the rotating rod 24 to perform mechanical transmission, pushing the peristaltic pump body 35 to draw paint from the paint tank 36 and spray it evenly on the polished surface through the paint spraying tube 38. The painting process achieves anti-corrosion treatment of the welding material surface, increases the durability and corrosion resistance of the welded part, and prevents external environmental factors from eroding the welded part.
[0030] In practical use, when the rotating rod 24 rotates counterclockwise, it drives the ratchet 31 to slide on the outer wall of the pawl 32. When the hydraulic cylinder 21 drives the connecting rod 22 to rise, the rack 23 drives the sprocket 25 to rotate clockwise. The sprocket 25 drives the rotating rod 24 to rotate clockwise. When the rotating rod 24 rotates clockwise, it drives the pawl 32 to rotate. The pawl 32 drives the collar 33 to rotate. The collar 33 drives the pulley 34 to rotate. The pulley 34 drives the output end of the peristaltic pump body 35 to rotate. The peristaltic pump body 35 draws paint from the paint tank 36 through the suction pipe 37 and sprays the polished area through the paint spray pipe 38 to improve the corrosion resistance of the welding material.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
