[0002] Coal mine pipelines refer to the pipeline systems used for transporting coal mine products, coal mine wastewater or other substances. Coal mine pipelines usually undertake important transportation and discharge functions and play a crucial role in coal mine production.

[0003] A coal mine pipeline rust removal device is a device used to remove the rust layer on the surface and inner wall of the pipeline to maintain the structural integrity of the pipeline and extend its service life.

[0004] After retrieval, the Chinese patent publication number: CN217097140U discloses an inner wall rust removal machine for pipelines, belonging to the field of pipeline treatment. The inner wall rust removal machine for pipelines includes a bottom plate. A motor is installed near the left side of the top surface of the bottom plate. A rotating shaft is fixedly connected to the output shaft of the motor. A transmission mechanism is arranged at the left end of the rotating shaft. A transmission is fixedly connected to the top surface of the bottom plate near the left side. A first grooved pulley is fixedly connected to the side wall of the output shaft of the transmission. A clamping mechanism is arranged at the output end of the transmission. A support plate is fixedly connected to the top surface of the bottom plate.

Turn on the cylinder 72, which will drive the control plate 73 to move through the air rod. When the control plate 73 moves, it will drive the connecting block 75 connected thereto through the slide bar 751. The connecting block 75 will drive the support rod 74 to move. When the support rod 74 moves, the slide bar 751 on the connecting block 75 will slide along the control groove 731 and drive the connecting plate 76 connected thereto to move, so as to adjust the distance between the multiple wire brushes 77 to make it adaptable to the inner wall of the pipeline. Then, turn on the power assembly 6 to make the second motor 63 drive the rotating shaft 64 to rotate, and make the rotating shaft 64 drive the rust removal assembly 7 connected thereto to rotate. At the same time, turn on the electric push rod 8 to drive the rust removal assembly 7 to move back and forth to remove rust from the inner wall of the pipeline. After the rust removal is completed, turn off the first motor 23, and then remove the pipeline from the rotating assembly 2.
