[0032] One end of the first driving bevel gear 23 away from the second driving bevel gear 28 is rotatably clamped on the support frame 8, and the rotating clamping ring 26 is rotatably clamped inside the first limiting column 9. The upper end of the control bevel gear 29 is fixedly connected to the bottom end of the rotating wheel 10, and the control bevel gear 29 can be driven to rotate by the rotating wheel 10.

[0033] The second control gear 27 and the first control gear 25 are respectively meshed and connected with the arc-shaped adjustment tooth rings 42 in the two cleaning parts 30. The second control gear 27 and the first control gear 25 with opposite rotation directions can drive the two semicircular arc-shaped adjustment tooth rings 42 to rotate synchronously in opposite directions along the limit plate 34 to achieve 360° annular polishing of the steel pipe 3. The driving rubber roller 18 is distributed on both sides of the steel pipe 3, and the driving rubber roller 18 is in compression contact with the outside of the steel pipe 3. The rotating driving rubber roller 18 can drive and transport the steel pipe 3. The stopped driving rubber roller 18 can position the steel pipe 3 between the middle part of the driving rubber roller 18, and there is a large friction between the steel pipe 3 and the driving rubber roller 18, so that the steel pipe 3 can be stable and will not rotate during the polishing process of the steel pipe 3.

[0034] Working principle: First, the device is fixedly installed by the fixing plate 6, and the steel pipe 3 is placed and inserted into the limiting support ring 17, so that the front end outer wall of the steel pipe 3 is in contact with the symmetrically distributed driving rubber rollers 18. At this time, the second motor 19 installed under the support frame 8 is synchronously started to drive the synchronous driving wheel 21 to rotate in the corresponding direction. The rotating synchronous driving wheels 21 realize synchronous rotation with each other through the driving belt 20. The rotating synchronous driving wheel 21 can drive the driving rubber rollers 18 to rotate synchronously, and the rotating synchronous driving wheel 21 can drive the steel pipe 3. Since the interior of the limiting support ring 17 rotates uniformly The rotating ball 16 is fixedly installed, so that the steel pipe 3 is limitedly driven between the driving rubber rollers 18 and passes through the limiting support ring 17. When the steel pipe 3 is conveyed and fed in the limiting support ring 17, when it is necessary to polish and clean the designated position and the area to be processed on the steel pipe 3, the area is moved to the inside of the first polishing and cleaning mechanism 1 or the second polishing and cleaning mechanism 2 to stop conveying. By setting the first polishing and cleaning mechanism 1 and the second polishing and cleaning mechanism 2, the steel pipe 3 can be polished and cleaned at the end and the middle of the steel pipe 3 during the conveying process. After the steel pipe 3 stops, the first motor 12 is started.The first motor 12 drives the driving wheel 13 to rotate forward and backward. The driving wheel 13 that rotates forward and backward can drive the rotating wheel 10 to rotate forward and backward through the synchronous belt 11. The rotating rotating wheel 10 can drive the control bevel gear 29 located at its bottom to rotate forward and backward. The rotating control bevel gear 29 can drive the first driving bevel gear 23 and the second driving bevel gear 28 to rotate. Since the rotating rod between the first driving bevel gear 23 and the first control gear 25 rotates and penetrates and is inserted in the middle of the rotating snap ring 26, the second control gear 27 and the second driving bevel gear 28, the second driving bevel gear 28 drives the second control gear 2 The direction of rotation is always opposite to the rotation direction of the first control gear 25 driven by the first driving bevel gear 23. Therefore, the arc-shaped adjusting toothed ring 42 at the bottom thereof can be driven to slide synchronously along the second limiting slot 45 through the second control gear 27 and the first control gear 25. In the process of the arc-shaped adjusting toothed ring 42 sliding along the second limiting slot 45, the rotation limiting snap ring 44 connected to the arc-shaped adjusting toothed ring 42 is clamped in the second limiting slot 45 to play a limiting role. The second limiting column 43 is clamped in the first limiting slot 41 to play a limiting role, so that the arc-shaped adjusting toothed ring 42 is stable and stable during the rotation process. , and since the two arc-shaped adjusting toothed rings 42 slide in opposite directions during the rotation process, the second electric hydraulic push rod 39 is started to control the sliding control block 40 to slide downward along the inside of the adjusting control plate 35, so that the mounting plate 36 and the second polishing sand ring 33 can be displaced downward so that the second polishing sand ring 33 fits the outer wall of the steel pipe 3, so that the two arc-shaped adjusting toothed rings 42 can rotate and utilize the second polishing sand ring 33 to achieve 360° annular grinding and polishing processing on the steel pipe 3, so that the two arc-shaped adjusting toothed rings 42 can synchronously reciprocate along the second limit slot 45 to achieve 360° polishing processing on the steel pipe 3, and the two arc-shaped adjusting toothed rings 42 can synchronously reciprocate along the second limit slot 45 to achieve 360° polishing processing on the steel pipe 3. The second electric hydraulic push rod 39 controls the sliding control block 40 to slide along the adjustment control plate 35, so that the second polishing sand ring 33 can be pressed into contact with the outer wall of the steel pipe 3 of different diameters for grinding and polishing. The second polishing sand ring 33 can be removed and replaced by screwing the fastening bolt 37. After the steel pipe 3 is polished at the designated position by the first polishing cleaning mechanism 1 or the second polishing cleaning mechanism 2, the steel pipe 3 can be transported from the device for feeding by driving the rubber roller 18. During the use of the device, the designated position and area on the steel pipe 3 can be polished during the process of directional feeding of the steel pipe 3.
