The rotation of the screw two 48 makes the sliding block two 49 move left and right on the outer wall of the screw two 48, and the movement of the sliding block two 49 drives the connecting plate one 402 to move, thereby realizing the position adjustment of the lifting assembly 403, achieving the effect of derusting the pipeline comprehensively, and realizing the stable movement of the sliding block two 49 through the movement of the connecting plate one 402 to drive the sliding sleeve two 401 to slide on the outer wall of the sliding rod two 40.

[0033] Working principle:

[0034] The rotating shaft one 34 is rotated by starting the stepping motor one 35, thereby rotating the screw one 36, so that the sliding block one 39 moves left and right on the outer wall of the screw one 36. The sliding block one 39 moves to drive the front L-shaped plate 30 and the right fixing structure 5 to move, the position of the right fixing structure 5 is adjusted, so that the device can adapt to different lengths of the pipeline.

[0035] After the good position is adjusted through adjusting structure 3, the pipeline to be derusted is placed into the circular through hole 56 of the two fixing structures 5, and the rotating shaft 501 is rotated by starting the stepper motor four 502, and then the connecting shaft 59 is rotated by the belt 50, so as to drive the bidirectional threaded rod 503 to rotate. The rotation of the bidirectional threaded rod 503 makes the two sliding blocks four 505 move simultaneously in and out along the threaded direction, and then pushes the two connecting plates two 508 and the two trapezoidal clamping blocks 509 on the connecting plates two 508 to move close to the pipeline. Through the fixed connection of the connecting plates two 508 and the sliding sleeves three 507, the two sliding sleeves three 507 move along the sliding rods three 506, so as to ensure that the trapezoidal clamping blocks 509 can uniformly clamp the pipeline, and ensure that the pipeline is stable during the derusting process. Then, the driving motor 63 is started to rotate the gear 62, and the gear ring 61 rotates accordingly. The rotation of the gear ring 61 drives the limiting ring 54 to rotate through the fixed connection of the inner wall of the gear ring 61 and the limiting ring 54, so that the fixing ring 53 rotates in the bearing 52, and the pipeline is rotated through the fixed connection of the fixing ring 53 and the mounting disc 55. The lifting assembly 403 moves up and down through the control of the stepper motor three 4032, so that the sliding block three 4036 moves up and down along the threads of the screw three 4034. The movement of the sliding block three 4036 drives the connecting plate one 402 to move up and down, so as to realize the adjustment of the contact pressure of the steel brush 4039 and the surface of the pipeline, and adapt to the pipelines with different diameters, so as to ensure that the steel brush 4039 and the surface of the pipeline maintain appropriate contact pressure, improve the derusting efficiency and quality, and then the rotating shaft two 46 is rotated by starting the stepper motor two 47, and then the screw two 48 is rotated. The rotation of the screw two 48 makes the sliding block two 49 move left and right on the outer wall of the screw two 48, and the connecting plate one 402 is driven to move by the movement of the sliding block two 49, so as to realize the position adjustment of the lifting assembly 403, and achieve the effect of derusting the pipeline comprehensively, and the sliding sleeve two 401 slides on the outer wall of the sliding rod two 40 by the movement of the connecting plate one 402, so as to realize more stable movement of the sliding block two 49.
