Description

Technical Field

[0001] This utility model relates to the field of steel pipe rust removal technology, specifically a shot blasting rust removal device for the inner wall of steel pipe. Background Technology

[0002] In fields such as petrochemicals and bridge construction, the performance and quality of steel pipes directly affect the safety and service life of projects, making internal rust removal a crucial step in ensuring the quality of steel pipes.

[0003] Traditional shot blasting devices for steel pipe interiors often employ a fixed shot blasting mechanism, preventing the shot blaster from rotating flexibly. The shot continuously impacts specific areas of the steel pipe's inner wall in a fixed stream, resulting in significant differences in impact force at different locations. This leads to uneven rust removal, failing to meet the surface quality requirements of high-precision engineering projects. Furthermore, traditional devices rely on the friction between conveying rollers and the steel pipe surface for transport and rotation. The rollers contact the pipe at specific angles and pressures, causing the pipe to move and rotate simultaneously during rust removal. However, with prolonged high-frequency use, the roller surfaces wear severely, gradually reducing friction. This leads to slippage and poor rotation during transport, resulting in unstable pipe movement and further exacerbating the unevenness of shot blasting. Therefore, a new shot blasting device for steel pipe interiors is urgently needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a shot blasting device for removing rust from the inner wall of steel pipes, so as to solve the problem of uneven rust removal on the inner wall of steel pipes by traditional shot blasting devices mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a shot blasting and rust removal device for the inner wall of a steel pipe, comprising a main frame, a rotating hole provided on the side wall of the main frame, a controller fixedly connected to the bottom surface of the main frame, a uniform rust removal component provided on the inner wall of the rotating hole, a moving component provided on the surface of the main frame, and a linkage component provided on the side wall of the main frame.

[0006] The uniform rust removal assembly includes an adapter pipe rotatably connected to the inner wall of a rotating hole. One end of the adapter pipe is fixedly connected to a shot blasting box. The inner wall of the shot blasting box has multiple shot blasting holes. A shot blasting wheel is rotatably connected to the inner wall of the shot blasting box. A drive column is rotatably connected to the inner wall of the shot blasting box. One end of the shot blasting box is fixedly connected to a first motor. The surface of the drive column is fixedly connected to the output end of the first motor. The first motor is electrically connected to a controller.

[0007] Preferably, the movable component includes a movable plate, which is slidably connected to the surface of the main frame. The side wall of the main frame has a rotating hole, and a threaded column is rotatably connected to the inner wall of the rotating hole. A threaded block is threadedly connected to the surface of the threaded column, and the top surface of the threaded block is fixedly connected to the bottom surface of the movable plate.

[0008] Preferably, the linkage component includes a second motor, which is fixedly connected to the side wall of the main frame.

The surfaces of the first and second synchronous pulleys are fitted with the same synchronous belt, and the second motor is electrically connected to the controller.

[0009] Preferably, the bottom surface of the movable plate has two limiting grooves, the inner wall of the limiting grooves is slidably connected to limiting blocks, and the bottom surfaces of the two limiting blocks are fixedly connected to the surface of the main frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The uniform rust removal components cause the output of the first motor to rotate, which in turn drives the drive column to rotate. The drive column then drives the shot blasting wheel to rotate. The rapid rotation of the shot blasting wheel generates centrifugal force and airflow, propelling the shot inside the wheel at high speed to effectively strike the inner wall of the steel pipe, thus facilitating rust removal. Simultaneously, one end of the transfer pipe is fixedly connected to the side wall of the shot blasting box. When the transfer pipe rotates, it drives the shot blasting box to rotate, ensuring that the shot passing through multiple blasting holes is evenly distributed to the inner wall of the steel pipe, thereby improving the uniformity of shot blasting rust removal. The moving components cause the threaded column to rotate, thereby driving the threaded block to move. The movement of the threaded block drives the moving plate to move, and the movement of the moving plate facilitates the movement of the steel pipe on the surface of the moving plate forward at a constant speed, further improving the uniformity and stability of rust removal. Through the set linkage components, the output end of the second motor rotates, thereby driving the threaded column to rotate. The rotation of the threaded column, through the cooperation of the first synchronous pulley, the second synchronous pulley and the synchronous belt, drives the transfer pipe to rotate, thus facilitating the movement of the steel pipe while driving the rotation of the transfer pipe, thereby saving energy and reducing rust removal costs.

[0020] Please see Figure 1-4This utility model provides a shot blasting and rust removal device for the inner wall of steel pipes, including a main frame 1. A rotating hole 2 is provided on the side wall of the main frame 1. A controller 7 is fixedly connected to the bottom surface of the main frame 1. A uniform rust removal component 3 is provided on the inner wall of the rotating hole 2. A moving component 4 is provided on the surface of the main frame 1. A linkage component 5 is provided on the side wall of the main frame 1. The uniform rust removal component 3 includes a transfer pipe 301, which is rotatably connected to the inner wall of the rotating hole 2. One end of the transfer pipe 301 is fixedly connected to a shot blasting box 302. Multiple shot blasting holes 303 are opened on the inner wall of the shot blasting box 302. A shot blasting wheel 304 is rotatably connected to the inner wall of the shot blasting box 302. A drive column 305 is rotatably connected to the inner wall of the shot blasting box 302. A first motor 306 is fixedly connected to one end of the shot blasting box 302. The surface of 05 is fixedly connected to the output end of the first motor 306. The first motor 306 is electrically connected to the controller 7. Through the uniform rust removal component 3, the output end of the first motor 306 rotates, thereby driving the drive column 305 to rotate. The rotation of the drive column 305 drives the shot blasting wheel 304 to rotate. The shot blasting wheel 304 rotates rapidly, generating centrifugal force and wind force, thereby rapidly throwing out the shot inside the shot blasting wheel 304, which facilitates the impact on the inner wall of the steel pipe, thus facilitating the rust removal of the inner wall of the steel pipe. At the same time, one end of the transfer pipe 301 is fixedly connected to the side wall of the shot blasting box 302. When the transfer pipe 301 rotates, it drives the shot blasting box 302 to rotate, thereby facilitating the uniformity of shot blasting rust removal by the shot through multiple shot blasting holes 303 acting evenly on the inner wall of the steel pipe.

[0021] Furthermore, the moving component 4 includes a moving plate 401, which is slidably connected to the surface of the main frame 1. A rotating hole 402 is provided on the side wall of the main frame 1. A threaded post 403 is rotatably connected to the inner wall of the rotating hole 402. A threaded block 404 is threadedly connected to the surface of the threaded post 403. The top surface of the threaded block 404 is fixedly connected to the bottom surface of the moving plate 401. Through the moving component 4, the threaded post 403 rotates, thereby driving the threaded block 404 to move. The movement of the threaded block 404 drives the moving plate 401 to move. The movement of the moving plate 401 facilitates the movement of the steel pipe on the surface of the moving plate 401 forward at a constant speed, further improving the uniformity and stability of rust removal.

[0022] Furthermore, the linkage component 5 includes a second motor 501, which is fixedly connected to the side wall of the main frame 1. The surface of the threaded column 403 is fixedly connected to the output end of the second motor 501. A first synchronous pulley 502 is fixedly connected to the surface of the threaded column 403, and a second synchronous pulley 503 is fixedly connected to the surface of the adapter pipe 301. The same synchronous belt 504 is sleeved on the surfaces of the first synchronous pulley 502 and the second synchronous pulley 503. The second motor 501 is electrically connected to the controller 7. Through the linkage component 5, the output end of the second motor 501 rotates, thereby driving the threaded column 403 to rotate. The rotation of the threaded column 403, through the cooperation of the first synchronous pulley 502, the second synchronous pulley 503, and the synchronous belt 504, drives the adapter pipe 301 to rotate. This allows the adapter pipe 301 to rotate while the steel pipe is being moved, thus saving energy and reducing rust removal costs.

[0023] Furthermore, two limiting grooves 405 are provided on the bottom surface of the movable plate 401. Limiting blocks 406 are slidably connected to the inner wall of the limiting grooves 405. The bottom surfaces of the two limiting blocks 406 are fixedly connected to the surface of the main frame 1. The limiting grooves 405 and the limiting blocks 406 cooperate with each other to facilitate the limiting of the movable plate 401, thereby facilitating the parallel movement of the movable plate 401.

[0024] Furthermore, a conveying pipe 6 is rotatably connected to the inner wall of the transfer pipe 301, and the surface of the conveying pipe 6 is rotatably connected to the inner wall of the shot blasting box 302. The conveying pipe 6 facilitates the conveying of shot into the interior of the shot blasting box 302.

[0025] Furthermore, a storage battery 8 is fixedly connected to the bottom surface of the main frame 1. The storage battery 8 is electrically connected to the controller 7, the first motor 306, and the second motor 501. The storage battery 8 facilitates the supply of power to the controller 7, the first motor 306, and the second motor 501 in the event of a sudden power outage.

[0026] Working principle: The uniform rust removal component 3 causes the output end of the first motor 306 to rotate, thereby driving the drive column 305 to rotate. The rotation of the drive column 305, in turn, drives the shot blasting wheel 304 to rotate. The rapid rotation of the shot blasting wheel 304 generates centrifugal force and air force, which rapidly ejects the shot inside the shot blasting wheel 304, facilitating the impact on the inner wall of the steel pipe and thus removing rust. Simultaneously, one end of the transfer pipe 301 is fixedly connected to the side wall of the shot blasting box 302. When the transfer pipe 301 rotates, it drives the shot blasting box 302 to rotate, ensuring that the shot through multiple shot blasting holes 303 acts evenly on the inner wall of the steel pipe, thereby improving the uniformity of shot blasting rust removal. The movement is controlled by... Component 4 causes the threaded column 403 to rotate, thereby driving the threaded block 404 to move. The movement of the threaded block 404 drives the moving plate 401 to move. The movement of the moving plate 401 facilitates the movement of the steel pipe on the surface of the moving plate 401 forward at a constant speed, further improving the uniformity and stability of rust removal. Through the linkage component 5, the output end of the second motor 501 rotates, thereby driving the threaded column 403 to rotate. The rotation of the threaded column 403, through the cooperation of the first synchronous pulley 502, the second synchronous pulley 503 and the synchronous belt 504, drives the adapter pipe 301 to rotate. This facilitates the movement of the steel pipe while simultaneously driving the rotation of the adapter pipe 301, thereby saving energy and reducing rust removal costs.
