[0018] like Figure 1 , Figure 2 and Figure 5 As shown, a steel structure rust removal device includes: a base 20, which is rectangular in shape, and a support leg installed at the bottom of the base 20. This is existing technology and will not be described in detail here.
[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a rust removal structure is installed on the top of the base 20 for rust removal of the steel structure. The rust removal structure includes: a moving frame 31, a grinding wheel 34, an air inlet groove 35, and an air extraction box 36. The moving frame 31 is movably installed on the top of the front wall of the base 20. The grinding wheel 34 is rotatably connected to the bottom of the moving frame 31. The air inlet groove 35 is opened on one side wall of the moving frame 31. The air extraction box 36 is fixedly connected to the side wall of the moving frame 31 opposite to the air inlet groove 35. The grinding wheel 34 can grind and remove rust from the steel structure below.
[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the moving frame 31 is an L-shaped plate, the air inlet groove 35 is a rectangular groove, the opening of the suction box 36 faces the air inlet groove 35, and the grinding wheel 34 is located in the middle of the air inlet groove 35 and the suction box 36. The rust removal structure also includes an electric cylinder 30, a side column 32, a motor 33, a connecting pipe 37, a bag filter 38, a first sealing plate 39, and a second sealing plate 40. The electric cylinder 30 is fixedly connected to one side of the front wall of the base 20, and the top of the electric cylinder 30 can be fixedly connected to the side wall of the moving frame 31. The side column 32 is rotatably connected to the inner wall of the corner of the moving frame 31. The motor 33 is fixedly connected to the top of the moving frame 31, and the motor 33 can drive the grinding wheel 34 to rotate through a shaft coupling. The connecting pipe 37 is fixedly connected to the top of the suction box 36. The bag vacuum pump 38 is fixedly connected to the top side of the transfer frame 31. The other end of the connecting pipe 37 can be fixedly connected to the bag vacuum pump 38. The first sealing plate 39 is fixedly connected to the bottom of the rear wall of the transfer frame 31. The second sealing plate 40 is fixedly connected to the bottom of the front wall of the transfer frame 31. The retraction end of the electric cylinder 30 is fixedly connected to the wall of the transfer frame 31. The side column 32 is cylindrical. A rectangular slot is opened on the wall of the transfer frame 31 at the side column 32. The side column 32 is rotatably connected to the wall of the transfer frame 31 through a bearing installed at the top. The connecting pipe 37 can connect the vacuum box 36 and the cavity of the bag vacuum pump 38. The first sealing plate 39 is a rubber soft plate. The second sealing plate 40 is a rectangular plate. The second sealing plate 40 is obliquely placed on the wall of the transfer frame 31. In practical use, first place the rusted part of the steel structure to be derusted facing upwards on top of the base 20. At this time, the steel structure will be located on top of the symmetrical base columns 22. Then, push the steel structure downwards towards the grinding wheel 34. Then, control the retraction of the electric cylinder 30. The electric cylinder 30 can drive the moving frame 31 and all the structures on the wall of the moving frame 31 to move downwards synchronously. Then, the grinding wheel 34 will move synchronously with the descent of the moving frame 31. After the grinding wheel 34 and the rusted part on the top of the steel structure can be contacted, stop controlling the retraction of the electric cylinder 30. At this time, start the power supply of the motor 33 and the bag filter 38. The motor 33 can drive the grinding wheel 34 to rotate. At this time, turn the steel structure forward. As the steel structure is pushed, the rusted parts on its upper part come into contact with the grinding wheel 34 for grinding and rust removal. While the grinding wheel 34 is removing rust, the first sealing plate 39, the second sealing plate 40, and the air extraction box 36, together with the steel structure below, can form a separate space. At this time, as the bag filter 38 is turned on, air can be drawn from the air extraction box 36 through the connecting pipe 37. The air will enter the space formed from the air inlet slot 35, thereby adsorbing the dust generated during rust removal and accumulating it in the cavity of the bag filter 38. Then, the filter bag in the cavity of the bag filter 38 can filter the incoming dust and then discharge it from the exhaust port on the wall of the bag filter 38. In summary, by setting up a rust removal structure and utilizing the grinding wheel 34, a separate air extraction space is created through the structure below the moving frame 31 during rust removal, thereby adsorbing the dust generated during rust removal and preventing the smoke and dust from affecting the health of workers.
[0021] like Figure 1 , Figure 2 and Figure 5 As shown, the top of the base 20 is provided with a limiting structure, which includes: a fixed edge 21, a bottom column 22, a fixed plate 23, a limiting frame 24, an adjusting plate 25, and an adjusting groove 26. The fixed edge 21 is fixedly connected to one side of the top of the base 20. The bottom column 22 is symmetrically rotated and connected to the top of the base 20 through bearings. The fixed plate 23 is fixedly connected to one side of the front wall of the base 20 and is located at the electric cylinder 30. The limiting frame 24 is slidably connected to the top of the base 20. The position of the limiting frame 24 is related to the fixed edge 21, the bottom column 22, the fixed plate 23, the limiting frame 24, the adjusting groove 26, and the adjusting groove 26. With sides 21 facing each other, adjustment plate 25 is fixedly connected to the bottom of limit frame 24, adjustment groove 26 is opened on the top of base 20, fixed side 21 and fixed plate 23 are rectangular plates, the side wall of fixed side 21 can be flush with the arc surface of side column 32, one of the bottom columns 22 is located directly below the moving frame 31, a screw is installed in the adjustment groove 26, the wall of adjustment plate 25 is installed with a dust cover that can be sleeved with the screw, the screw can be threaded to the wall of adjustment plate 25, and the limit frame 24 is a rod with an L-shaped cross section; In practical use, when the steel structure is placed on top of the base 20, one end of the screw in the adjustment groove 26 can extend from the wall of the base 20 and be equipped with a handle. Turning the handle will drive the screw to rotate. Then, as the screw rotates, the adjustment plate 25 can be controlled to move the limit frame 24 towards or away from the fixed edge 21 on the top of the base 20. After the side wall of the limit frame 24 contacts the steel structure, the steel structure can be restricted to the top of the base 20. When the steel structure is pushed to move along the top of the base 20, the bottom column 22 can roll with the movement of the steel structure. In summary, by setting a limiting structure, steel structures of different sizes can be restricted to the top of the base 20, preventing the steel structures from shaking during rust removal on the top of the base 20, thereby improving the rust removal quality of this solution.
[0022] Working principle: Place the steel structure to be derusted with the rusted part facing upwards on top of the base 20. At this time, the steel structure will be located on top of the symmetrical bottom column 22. Then push the steel structure downwards towards the grinding wheel 34. Then, control the electric cylinder 30 to retract. The electric cylinder 30 can drive the moving frame 31 and all the structures on the wall of the moving frame 31 to move downwards synchronously. Then the grinding wheel 34 will move synchronously with the downward movement of the moving frame 31. After the grinding wheel 34 and the rusted part on the top of the steel structure can make contact, stop controlling the electric cylinder 30 to retract. At this time, start the power supply of the motor 33 and the bag vacuum pump 38. The motor 33 can drive the grinding wheel 34 to rotate. Then push the steel structure forward. As the steel structure is pushed, the rusted part on the top of the steel structure will make contact with the grinding wheel 34, thereby grinding and removing rust.
