Description

Technical Field

[0001] This utility model relates to the field of steel structure building technology, specifically to a rust removal device for steel structure buildings. Background Technology

[0002] In the field of steel structure construction, rust removal is a crucial step in ensuring building quality and durability. Traditional rust removal devices for steel structures mostly employ a single brush head design. Their working principle primarily involves a motor driving a single rust-removing brush head to rotate, using the friction between the brush head and the steel structure surface to remove rust. This type of device has been widely used for a long time and can play a certain role in some small construction projects or scenarios where rust removal efficiency requirements are not high.

[0003] However, with the rapid development of the construction industry and the increasing number of large steel structure building projects, the drawbacks of traditional single-brush head rust removal devices have gradually become apparent. Because they rely on a single brush head, the coverage area of ​​a single rust removal operation is extremely limited. When dealing with large areas of steel structure surfaces, a lot of time needs to be spent on repeated operations, resulting in low rust removal efficiency.

[0004] In terms of manual operation, traditional equipment also has many problems. In order to ensure the rust removal effect, operators need to frequently adjust the position and angle of the brush head to adapt to steel structures of different shapes and positions. This not only requires operators to have a high level of skill, but also requires a lot of energy and physical strength. The complexity of manual operation is high, and the labor cost accounts for too high a proportion of the entire rust removal project, which also increases the total cost of the project.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1-4A rust removal device for steel structures includes a vehicle body with two connecting frames 1. Each connecting frame 1 is equipped with rollers 2 and casters 3. The vehicle body can move flexibly via the combination of rollers 2 and casters 3. Connecting plates 22 are fixedly connected to the two connecting frames 1, and push handles 23 are fixedly connected to the connecting plates 22. The push handles 23 are securely connected to the vehicle body via the connecting plates 22, providing a convenient point of application for the operator. Combined with the rollers 2 and casters 3, it facilitates manual adjustment of the device's position, improving operational flexibility and practicality. Multiple support columns 4 are fixedly connected to the top of the two connecting frames 1, and a top plate 5 is fixedly connected to the top of the multiple support columns 4. The device also includes a lifting mechanism for lifting... The mechanism is connected to the top plate 5. The lifting mechanism includes a first electric push rod 14. The output end of the first electric push rod 14 passes through the top plate 5 and is connected to a fixed plate 15. The bottom end of the fixed plate 15 is fixedly connected to multiple connecting columns 7. Multiple first guide holes are opened at the top of the top plate 5. A first guide rod 16 is slidably fitted in the first guide hole. The bottom end of the first guide rod 16 is fixedly connected to the fixed plate 15, so that the first electric push rod 14 drives the fixed plate 15 to lift and lower, realizing the automated control of the lifting and lowering of the rust removal mechanism. The cooperation structure between the first guide rod 16 and the first guide hole effectively limits the movement trajectory of the fixed plate 15, avoids deviation during the lifting and lowering process, and improves the stability of the rust removal mechanism during operation.

[0028] It should also be noted that the rust removal mechanism includes a housing 6, with multiple connecting columns 7 fixedly connected to the top of the housing 6. The tops of the multiple connecting columns 7 are fixedly connected to the lifting mechanism. A motor 8 is installed at the top of the housing 6. The output end of the motor 8 passes through the housing 6 and is connected to a first gear 9. Three rotating holes are opened at the bottom of the housing 6. A rotating rod 10 is rotatably connected inside the rotating holes. The top of the rotating rod 10 extends into the housing 6 and is fixedly connected to a second gear 11. The second gear 11 meshes with the first gear 9. A mounting plate 12 is fixedly connected to the bottom of the rotating rod 10. Rust removal brushes 13 are connected to the mounting plate 12. The transmission method of the first motor 8 driving the first gear 9 and the three gears meshing drives the three rust removal brushes 13 to work synchronously, improving rust removal efficiency and coverage.

[0029] It should be further explained that the anti-deviation mechanism is connected to two connecting frames 1. The anti-deviation mechanism includes two second electric push rods 17, which are respectively installed on the two connecting frames 1. The output end of the second electric push rod 17 passes through the connecting frame 1 and is connected to a mounting box 18. Multiple rotating columns 19 are rotatably connected inside the mounting box 18. The two second electric push rods 17 control the structures on both sides respectively, and the position of the mounting box 18 can be flexibly adjusted according to the size of the steel structure to adapt to workpieces of different specifications. The rotating columns 19 are designed to produce rolling friction when the device contacts the steel structure, reducing movement resistance and avoiding scratches on the surface of the steel structure. Multiple second guide holes are provided on the connecting frame 1, and the second guide holes are slidably fitted with the first The second guide rod 20 is fixedly connected to the mounting box 18. The cooperation between the second guide rod 20 and the second guide hole provides precise guidance for the movement of the mounting box 18, ensuring that the mounting box 18 moves in a straight line when the second electric push rod 17 is driven, further improving the anti-deviation effect and ensuring the adhesion accuracy between the rust removal brush 13 and the steel structure surface. Protective shells 21 are fixedly connected to both connecting brackets 1. The protective shells 21 are used to protect the second electric push rod 17 and the second guide rod 20. The protective shells 21 can effectively isolate rust, dust and external impurities generated during the rust removal process, preventing them from entering the second electric push rod 17 and the second guide rod 20 and affecting the operating accuracy and service life, thus reducing equipment maintenance costs.

[0030] In summary, the working principle and process of this steel structure rust removal device are as follows: When in use, first move the device to the desired position, then start the second electric push rod 17 so that the rotating column 19 in the mounting box 18 lightly touches both sides of the steel structure; then turn on the first electric push rod 14 so that the first electric push rod 14 lowers the rust removal brush 13 to a distance of 5-10mm from the steel structure through the box 6, start the motor 8 so that the motor 8 drives the three rust removal brushes 13 to rotate through the first gear 9 and three second gears 11, and then lowers them at a uniform speed through the first electric push rod 14 to contact the steel structure to start rust removal. The operator pushes the device at a uniform speed along the steel structure through the push handle 23 to remove rust.

[0031] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
