[0031] As Figures 1-11 shown, the embodiment of the present utility model provides a rust removal device for construction engineering, which includes a U-shaped workbench 1, a rotating grinding assembly 2, and a grinding and rust removal assembly 3. An arc-shaped through hole 6 is formed on the upper surface of the U-shaped workbench 1, and two rotating through holes 8 are symmetrically formed on the upper surface of the U-shaped workbench 1. Two movable through holes 5 are symmetrically formed on the outer wall of the U-shaped workbench 1. The rotating grinding assembly 2 is arranged in the movable through holes 5, the rotating through holes 8, and the arc-shaped through hole 6. The grinding and rust removal assembly 3 is arranged on the upper surface of the U-shaped workbench 1. A steel bar 4 is arranged on the rotating grinding assembly 2. The rotating grinding assembly 2 is used to assist the steel bar 4 to rotate.

The first servo motor 20 is arranged on the outer wall of one of the moving blocks 21. The output shaft of the first servo motor 20 penetrates through the moving block 21 and is arranged at one end of the first rotating rod 25. The bottom ends of the two springs 22 are arranged on the upper surfaces of the corresponding moving blocks 21, and the top ends of the two springs 22 are arranged on the inner top walls of the corresponding movable through holes 5. The two round rods 27 are arranged on the inner walls of the corresponding rotating through holes 8, and the two first belt pulleys 23 are arranged on the outer walls of the corresponding round rods 27.

The grinding and rust-removing assembly 3 is used in cooperation with the first grinding sand belt loop 24.

The moving block 21 drives the first grinding sand belt loop 24 to move downward through the first rotating rod 25 and the second belt pulley 26, so as to stretch the position of the first grinding sand belt loop 24 through the first belt pulley 23, so that the first grinding sand belt loop 24 is closely attached to the steel bar 4.

[0033] In this embodiment, specifically, the grinding and rust-removing assembly 3 includes a hydraulic push rod 30, a first U-shaped mounting plate 31, a second U-shaped mounting plate 32, an H-shaped mounting plate 33, a second grinding sand belt loop 34, two third belt pulleys 35, two second rotating rods 36, and a second servo motor 37. Among them, the first U-shaped mounting plate 31 is arranged on the upper surface of the U-shaped workbench 1, and the second U-shaped mounting plate 32 is slidably connected to the inner wall of the first U-shaped mounting plate 31. The hydraulic push rod 30 is arranged on the upper surface of the first U-shaped mounting plate 31.

The H-shaped mounting plate 33 is arranged on the inner wall of the second U-shaped mounting plate 32.

The output shaft of the second servo motor 37 penetrates through the H-shaped mounting plate 33 and is arranged at one end of one of the second rotating rods 36. Through the above settings, the output shaft of the second servo motor 37 drives one of the second rotating rods 36 to rotate. One of the second rotating rods 36 drives the second grinding sand belt loop 34 to rotate through one of the third belt pulleys 35. The second grinding sand belt loop 34 is assisted to rotate by the other third belt pulley 35. The second grinding sand belt loop 34 is used to assist the steel bar 4 to move on the first grinding sand belt loop 24, so as to further grind and remove rust from the steel bar 4 on the first grinding sand belt loop 24.

[0034] In this embodiment, specifically, first sliding grooves 9 are symmetrically formed in the inner wall of the movable through hole 5. First sliding blocks 10 are symmetrically arranged on the outer wall of the moving block 21. The outer walls of the first sliding blocks 10 are slidably connected to the inner walls of the first sliding grooves 9. Through the above settings, the first sliding blocks 10 slide in the first sliding grooves 9, which can not only assist the moving block 21 to move, but also limit the position of the moving block 21.

[0035] In this embodiment, specifically, second sliding grooves 11 are uniformly formed in the inner wall of the first U-shaped mounting plate 31. Second sliding blocks 12 are uniformly arranged on the outer wall of the second U-shaped mounting plate 32. The outer walls of the second sliding blocks 12 are slidably connected to the inner walls of the second sliding grooves 11. Through the above settings, the second sliding blocks 12 slide in the second sliding grooves 11, which can not only assist the second U-shaped mounting plate 32 to move, but also stabilize the moving position of the second U-shaped mounting plate 32.

[0036] In this embodiment, specifically, a control panel 7 is arranged on the outer wall of the U-shaped workbench 1. The control panel 7 is electrically connected to the first servo motor 20, the hydraulic push rod 30, and the second servo motor 37 through wires.

[0037] When the utility model is working: relevant personnel move the steel bar 4 to the first abrasive belt loop 24 on the arc-shaped through hole 6, so that the first abrasive belt loop 24 is in contact with the arc-shaped through hole 6. Then, the elastic potential energy of the spring 22 is used to push the moving block 21 to move downward. The moving block 21 drives the first abrasive belt loop 24 to move downward through the first rotating rod 25 and the second pulley 26. Thus, the first pulley 23 is used to stretch the position of the first abrasive belt loop 24, so that the first abrasive belt loop 24 is in close contact with the steel bar 4.

[0038] After that, relevant personnel control the hydraulic push rod 30 to start through the control panel 7. The piston rod of the hydraulic push rod 30 drives the second U-shaped mounting plate 32 to move downward. The second U-shaped mounting plate 32 drives the H-shaped mounting plate 33 to move downward. The H-shaped mounting plate 33 drives the second abrasive belt loop 34 to be in close contact with the steel bar 4.

[0039] After that, relevant personnel control the first servo motor 20 and the second servo motor 37 to start simultaneously through the control panel 7. The output shaft of the first servo motor 20 drives the first rotating rod 25 to rotate. The first rotating rod 25 drives the second pulley 26 to rotate. The second pulley 26 drives the first abrasive belt loop 24 to rotate. The first abrasive belt loop 24 is assisted to rotate by the first pulley 23. Thus, the first abrasive belt loop 24 drives the steel bar 4 to rotate and rust-remove on the second abrasive belt loop 34.

[0040] At this time, the output shaft of the second servo motor 37 drives one of the second rotating rods 36 to rotate. One of the second rotating rods 36 drives the second abrasive belt loop 34 to rotate through one of the third pulleys 35. The second abrasive belt loop 34 is assisted to rotate by the other third pulley 35. The second abrasive belt loop 34 is used to assist the steel bar 4 to move on the first abrasive belt loop 24. Thus, the steel bar 4 is further rust-removed by grinding on the first abrasive belt loop 24, and the steel bar 4 is assisted to move out of the first abrasive belt loop 24.

[0041] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art in the technical field disclosed by the utility model can easily think of various changes or substitutions within the technical scope disclosed by the utility model, and these should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
