"Buildings" refer to projects with roofs, beams, columns, walls, foundations, and internal spaces that can meet people's needs for production, residence, study, and public activities.

[0003] During the construction process, welding, connection, piping, lightning protection and other construction processes require the steel bars to be embedded in the structure to ensure the subsequent construction can proceed smoothly. The steel bars need to be derusted before embedding, so that the steel bars will not rust immediately when exposed to the outside after embedding, avoiding the weakening of the strength of the steel bars, thereby increasing the safety and stability of the building.

[0004] The existing technology has the following problems:

[0005] In actual use of existing devices, some existing steel bar rust removal methods mostly use scrapers, steel wool, gauze and other tools to manually process rusted steel bars, which is not only labor-intensive, but also has low rust removal quality and efficiency. At the same time, the existing devices cannot effectively fix the steel bars, resulting in the steel bars being more likely to shake and fall off during the rust removal process, making the device unstable, and thus making the rust removal effect of the device not good enough.

[0025] like Figure 1-5As shown, the utility model provides a rust removal device for embedded exposed steel bars in construction projects, including a mounting shell 1, a screw rod 2 is rotatably connected inside the mounting shell 1, fixing mechanisms 3 are symmetrically installed on the left and right sides of the mounting shell 1, a rust removal mechanism 4 is installed on the upper end of the mounting shell 1, a motor 5 is fixedly installed on the right side of the inside of the mounting shell 1, a threaded seat 6 is threadedly connected to the outside of the screw rod 2, a limiting block 7 is fixedly installed on the lower end of the threaded seat 6, a limiting groove 8 is provided at the inner bottom end of the mounting shell 1, and a bearing plate 9 is fixedly installed on the upper end of the threaded seat 6.

[0026] The output end of the motor 5 is transmission connected to the right end of the screw rod 2, the limit block 7 is matched with the limit groove 8, and is slidably connected. When the threaded seat 6 moves, it will drive the limit block 7 to slide synchronously in the limit groove 8, thereby making the movement of the threaded seat 6 smooth and at the same time limiting the threaded seat 6.

[0027] Through the fixing mechanism 3, the hydraulic cylinder 1 32 and the hydraulic cylinder 2 36 can be used to push the clamp 1 33 and the clamp 2 37 to move, so that the distance between the clamp 1 33 and the clamp 2 37 can be adjusted, so that the steel bar can be clamped and fixed on the fixing frame 31, so that it will not shake during rust removal, thereby avoiding the steel bar from falling off, thereby improving the stability of the device, and through the rust removal mechanism 4, the movable plate 46 can be used to drive the upper fixed plate 45 to move downward, so that the upper fixed plate 45 can contact the steel bar, and then the rust removal brush 47 can contact the outer wall of the steel bar, and then the threaded seat 6 can drive the rust removal structure to move through the bearing plate 9, so that the rust removal brush 47 can move back and forth horizontally on the steel bar, so that the rust removal operation can be performed on the outside of the steel bar, thereby reducing the labor intensity of manual labor and improving the quality and efficiency of rust removal.

[0028] like Figure 3 As shown, the fixing mechanism 3 includes a fixing frame 31, the bottom end of the fixing frame 31 is symmetrically fixedly connected to the left and right sides of the mounting shell 1, a hydraulic cylinder 1 32 is fixedly installed inside the fixing frame 31, a clamping plate 1 33 is fixedly installed on the top of the output rod of the hydraulic cylinder 1 32, support rods 34 are symmetrically installed at the four corners of the upper end of the fixing frame 31, a top plate 35 is installed on the top of the support rods 34, a hydraulic cylinder 2 36 is fixedly installed on the upper end of the top plate 35, and a clamping plate 2 37 is fixedly installed on the top of the output rod of the hydraulic cylinder 2 36.

[0029] The lower end of the support rod 34 is symmetrically fixedly connected to the four corners of the upper end of the fixing frame 31 .

[0030] The upper end of the support rod 34 is symmetrically fixedly connected to the four corners of the lower end of the top plate 35.

[0031] The two ends of the steel bar can be clamped and fixed by the provided clamping plate 1 33 and the clamping plate 2 37, so that the steel bar will not move or fall off during rust removal.

[0032] As shown Figure 4-5 in the figure, the rust removal mechanism 4 includes a mounting frame 41. The front end of the mounting frame 41 is fixedly connected to the rear end face of the bearing plate 9. A screw rod 42 is rotatably connected to the middle inside of the mounting frame 41. Guide rods 43 are symmetrically and fixedly installed at both ends inside the mounting frame 41. A lower fixed plate 44 is fixedly installed at the upper end of the bearing plate 9. An upper fixed plate 45 is installed above the lower fixed plate 44. A movable plate 46 is fixedly installed on the rear end face of the upper fixed plate 45. Rust removal brushes 47 are symmetrically and fixedly installed on the opposite faces of the lower fixed plate 44 and the upper fixed plate 45. A threaded sleeve 48 is fixedly installed in the middle of the movable plate 46. Slide sleeves 49 are symmetrically and fixedly installed on both the left and right sides of the movable plate 46. A second motor 410 is fixedly installed on the top of the mounting frame 41.

[0033] The mounting frame 41 is in a "C" shape. The outside of the screw rod 42 is threadedly connected to the inside of the threaded sleeve 48. The outside of the guide rod 43 is slidably connected to the inside of the slide sleeve 49.

[0034] Both the lower fixed plate 44 and the upper fixed plate 45 are arc-shaped. The output end of the second motor 410 is drivingly connected to the top of the screw rod 42.

[0035] When the threaded sleeve 48 drives the upper fixed plate 45 to move downward through the movable plate 46, it will drive the slide sleeve 49 to slide synchronously and guidingly on the guide rod 43, thereby improving the stability of the movement of the movable plate 46 and the upper fixed plate 45.

[0036] Next, the working principle of the rust removal device for the embedded and exposed steel bars in the building project will be specifically described.

Then, the hydraulic cylinder 1 32 and the hydraulic cylinder 2 36 can be started, so that the hydraulic cylinder 1 32 and the hydraulic cylinder 2 36 can push the clamping plate 1 33 and the clamping plate 2 37 to move under the steel bar, so that the clamping plate 1 33 and the clamping plate 2 37 are in contact with the two ends of the steel bar, so that the steel bar can be clamped and fixed, so that the steel bar will not fall off during rust removal, and then the motor 2 410 is started, and the motor 2 410 drives the screw 42 to rotate in the threaded sleeve 48, so that the screw 42 can drive the movable plate through the threaded sleeve 48 connected by thread 46 and the upper fixed plate 45 move downward, so that the upper fixed plate 45 contacts the upper end of the steel bar, so that the rust removal brush 47 on the lower fixed plate 44 and the upper fixed plate 45 fits with the outside of the steel bar, and finally the motor 5 can be started, and the motor 5 drives the screw rod 2 to rotate, so that the screw rod 2 drives the threaded seat 6 connected with the thread to perform horizontal reciprocating motion left and right, so that the threaded seat 6 drives the lower fixed plate 44 and the upper fixed plate 45 to move synchronously through the bearing plate 9, so that the rust removal brush 47 can fully remove rust from the steel bar, thereby reducing the labor intensity of manual labor. At the same time, the steel bar can also be sprayed with a little rust remover on the surface of the steel bar when it is rusted, thereby improving the rust removal effect of the steel bar and improving the quality of the rust removal of the steel bar.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
