Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and in particular to a rust removal device for steel structure surfaces. Background Technology

[0002] In steel structure fabrication, rust on the steel surface affects its strength and corrosion resistance, thereby reducing the overall service life and safety of the structure. Rust removal can effectively remove rust, reduce surface contamination, and improve the service life and performance of the steel.

[0003] A search revealed that patent document CN221159810U discloses a rust removal device for steel structures. This device uses a positioning component to fix the steel structure, and a movable component in conjunction with a rust removal component to remove rust from the surface of the steel structure. After one side of the steel structure is rust-removed, a rotating component can be used to flip the steel structure, allowing for rust removal on other sides. This method offers superior performance, saves on rust removal steps, and improves efficiency.

[0004] Although the above-mentioned rust removal device has solved some of the existing shortcomings, in actual use, when removing rust from pipes and other irregularly shaped parts, the use of abrasive belts makes it difficult to remove rust from corners, grooves and inner walls.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figure 1-Figure 3 As shown, a rust removal device for steel structure surfaces is disclosed, comprising an immersion tank 1, with a partition 2 fixedly connected inside the immersion tank 1, dividing the immersion tank 1 into two areas: an immersion area for rust removal agent and a rinsing area. Two drain pipes 3 are fixedly connected to the outer wall of the immersion tank 1, and a liquid inlet pipe 4 is fixedly connected to the outer wall of the immersion tank 1. One end of the liquid inlet pipe 4 is fixedly connected to a pump body, which is selected as a corrosion-resistant pump body. Two first motors 5 are fixedly connected to the outer wall of the immersion tank 1, and long screws 6 are fixedly connected to the outer wall of the output shafts of the two first motors 5. One end of each long screw 6 is rotatably connected to a bearing, and the outer ring of the bearing is fixedly connected to the outer wall of the immersion tank 1.

[0023] The outer walls of the two long screws 6 are threaded with rectangular moving blocks 7. The tops of the two rectangular moving blocks 7 are fixedly connected to support seats 8. The outer walls of the soaking pool 1 are fixedly connected with four guide rails 9. The four guide rails 9 are slidably connected to the outer walls of the two support seats 8 in pairs. The outer walls of the four guide rails 9 are rotatably embedded with multiple balls to reduce friction and facilitate the sliding of the support seats 8.

[0024] Electric push rods 10 are fixedly connected to the top of both support bases 8. The synchronization problem between the two first motors 5 and the two electric push rods 10 is solved by the existing synchronous controller. The main model is selected according to the actual situation. Connecting blocks 11 are fixedly connected to the top of the output end of the two electric push rods 10. One end of the two connecting blocks 11 is fixedly connected to the same U-shaped frame 12. A U-shaped mesh frame 13 is fixedly connected to the bottom of the U-shaped frame 12. The U-shaped mesh frame 13 is supported by the U-shaped frame 12.

[0025] The outer wall of the U-shaped frame 12 is provided with a placement mechanism, which includes a second motor 14. The interior of the U-shaped mesh frame 13 is rotatably connected to two drive rollers 15 through existing roller bearings. The outer wall of the U-shaped mesh frame 13 is provided with a circular hole, and the inner wall of the circular hole is rotatably connected to one end of one of the drive rollers 15 through existing roller bearings. The outer wall of the U-shaped frame 12 is fixedly connected to the outer wall of the second motor 14.

[0026] One of the drive rollers 15 and the outer wall of the output shaft of the second motor 14 are fixedly connected to a synchronous pulley 16. The outer walls of the two synchronous pulleys 16 are fitted with the same synchronous toothed belt 17. The outer walls of the two drive rollers 15 are fitted with the same stainless steel conveyor belt 18. The operation of the second motor 14 drives the synchronous pulleys 16 and the synchronous toothed belt 17 to rotate, thereby causing the drive rollers 15 and the stainless steel conveyor belt 18 to rotate.

[0027] The outer wall of the U-shaped frame 12 is equipped with a cleaning mechanism, which includes a hollow rectangular water storage plate 19. The outer wall of the U-shaped frame 12 is fixedly connected to the outer wall of the rectangular water storage plate 19. A water inlet pipe 21 is fixedly connected to the top of the rectangular water storage plate 19. Multiple nozzles 20 are evenly fixed and interconnected at the bottom of the rectangular water storage plate 19. The multiple nozzles 20 spray water in a fan shape. One end of the water inlet pipe 21 passes through the outer wall of the U-shaped frame 12 and is fixedly interconnected with a water pump.

[0028] Working principle: During use, the two electric push rods 10 rotate, driving the two connecting blocks 11 to move upwards, causing the U-shaped frame 12 to rise and move out of the soaking tank 1. The steel structure to be derusted is then placed on the stainless steel conveyor belt 18. The two electric push rods 10 continue to rotate, driving the U-shaped frame 12 downwards into the soaking tank 1, positioned on one side of the partition 2. The pump body operates, delivering the rust remover to the liquid addition pipe 4, flowing into the soaking tank 1, positioned on one side of the partition 2. Simultaneously, the steel structure is immersed in the rust remover for rust removal. After rust removal is completed, the two push rods move the U-shaped frame 12 upwards a certain distance, above the height of the partition 2. The two first motors 5 rotate, driving the two long screws 6 to rotate. The rotation of rod 6 drives two rectangular moving blocks 7 to move. The movement of the two rectangular moving blocks 7 drives two support seats 8 and two electric push rods 10 to move, and at the same time drives the U-shaped frame 12 to move horizontally, placing it on the other side of the partition 2. The operation of the two electric push rods 10 drives the U-shaped frame 12 to move downward into the soaking tank 1. The water pump operates to transport external water to the rectangular water storage plate 19 through the water inlet pipe 21, and then sprays water out through multiple nozzles 20 to rinse away excess rust remover from the steel structure after rust removal. Subsequently, the steel structure is driven by the operation of the second motor 14 to drive the synchronous pulley 16 and the synchronous toothed belt 17 to rotate, causing the drive roller 15 and the stainless steel conveyor belt 18 to rotate, and sending the steel structure out from the U-shaped mesh frame 13.
