When the steel pipe is transported through the ring body, the outer wall of the steel pipe is polished by the polishing mechanism, and the driving mechanism drives the gear ring to drive the rotating ring to rotate, so that the polishing mechanism rotates along the outer circumference of the steel pipe, so as to realize the polishing of the outer circumference of the steel pipe, and then the conveying mechanism located on the side of the ring body away from the polishing mechanism conveys the polished end of the steel pipe, thereby realizing automatic polishing of the steel pipe, reducing the trouble of manual polishing of the steel pipe, and improving the efficiency of the polishing work.

[0034] When the steel pipe is transported on the concave frame 5, the second electric push rod 651 is started to drive the guide roller 652 to approach the steel pipe and contact the outer wall of the steel pipe, so that the guide roller 652 can guide the transported steel pipe and reduce the possibility of the steel pipe being deviated during transportation.

[0035] like Figure 2 and Figure 5 As shown, the polishing mechanism 7 includes a first electric push rod 71, a first motor 72 and a polishing wheel 73. The first electric push rod 71 is vertically installed on the outer end face of the rotating ring 3 away from the ring body 2, and the first electric push rod 71 is arranged radially along the rotating ring 3. The first motor 72 is horizontally installed on the output end of the first electric push rod 71. The output end of the first motor 72 is coaxially fixed with the first rotating shaft 721, and the polishing wheel 73 is coaxially fixed to the outer side wall of the end of the first rotating shaft 721 away from the first motor 72. The outer peripheral surface of the rotating ring 3 is coaxially fixed with the ring gear 31, and the outer wall of the ring body 2 is provided with a driving mechanism 4 that can drive the ring gear 31 to rotate.

[0037] like Figure 2 , Figure 6 and Figure 7 As shown, an annular blowing pipe 21 is fixedly connected to the inner wall of the ring body 2, and a plurality of air nozzles 211 connected to the blowing pipe 21 are installed on the side wall of the blowing pipe 21. The plurality of air nozzles 211 are arranged to point obliquely to the axis direction of the ring body 2. A blowing pipe 22 is fixedly connected to the inner part of the ring body 2 near the position of the second rotating shaft 411. One end of the blowing pipe 22 is connected to the external environment, and the other end is fixedly connected to the side wall of the blowing pipe 21 and connected to the blowing pipe 21. The blowing pipe 22 is away from the outer wall of the ring body 2. A filter is provided on the inner wall of the end of the blowing pipe 21, and a rotating shaft 23 is coaxially connected to the inner wall of the blowing pipe 22.

The end of the rotating shaft 23 away from the blowing pipe 21 passes through the filter and extends to the outside of the blowing pipe 22. A second transmission assembly 24 is provided on the outer wall of the ring body 2 close to the rotating shaft 23. The second transmission assembly 24 can enable the second rotating shaft 411 to drive the rotating shaft 23 to rotate.

[0038] When the second motor 41 drives the second rotating shaft 411 to rotate, the second rotating shaft 411 drives the rotating shaft 23 and the fan blades 231 to rotate through the second transmission assembly 24. The fan blades 231 will form an airflow around the air during rotation, and transport the airflow to the blowing pipe 21 through the blowing pipe 22 and then spray it out from the air nozzle 211. During the steel pipe conveying and polishing process, the gas sprayed by the air nozzle 211 will spray and clean the outer wall of the polished end of the steel pipe, thereby reducing the trouble of manually cleaning polishing residues and reducing manual labor intensity.

[0039] like Figure 2 , Figure 6 and Figure 7As shown, the second transmission assembly 24 includes a gear box 241, a first pulley 242, a second pulley 243, a belt 244, a first bevel gear 245 and a second bevel gear 246. The gear box 241 is installed on the outer wall of the ring body 2 close to the rotating shaft 23. The low-speed input end of the gear box 241 is coaxial with the second rotating shaft 411, and the high-speed output end of the gear box 241 is perpendicular to the axis box of the rotating shaft 23. The first pulley 242 is coaxially fixed to the outer wall of the second rotating shaft 411, and the second pulley 2 43 is coaxially fixed on the outer wall of the low-speed input end of the gear box 241, and the belt 244 is tensioned and sleeved on the outside of the first pulley 242 and the second pulley 243.

[0040] With the cooperation of the first pulley 242, the second pulley 243 and the belt 244, the second rotating shaft 411 will drive the low-speed input end and the high-speed output end of the gear box 241 to rotate during the rotation process, and then the first bevel gear 245 and the second bevel gear 246 will cooperate to drive the rotating shaft 23 and the fan blades 231 to rotate, thereby converting the kinetic energy of the low-speed rotation of the second rotating shaft 411 into the kinetic energy of the high-speed rotation of the rotating shaft 23, so as to enable the fan blades 231 to better perform the rotating blowing work.

[0041] like Figure 2 and Figure 6 As shown, a third electric push rod 32 arranged radially along the rotating ring 3 is installed on the inner side wall of the rotating ring 3, and a cleaning brush 33 is provided at the output end of the third electric push rod 32. The third electric push rod 32 can make the cleaning brush 33 contact with the outer wall of the steel pipe.

[0042] Start the third electric push rod 32 to drive the cleaning brush 33 to move toward the center position of the rotating ring 3, so that the steel pipe can contact the cleaning brush 33 when feeding through the rotating ring 3. During the rotation of the rotating ring 3, the cleaning brush 33 will move along the outer circumference of the steel pipe to clean the outer surface of the steel pipe, thereby improving the cleaning effect of the polishing residue on the outer wall of the steel pipe.

[0043] Working principle: The steel pipe is placed on the concave frame 5 on the side of the ring body 2 close to the rotating ring 3, and the steel pipe is supported by the driving roller 61 and the driven roller 62 arranged on the concave frame 5. The driving motor 63 is started to drive the driving roller 61 to rotate. Under the cooperation of the first transmission component 64, the driving roller 61 drives the multiple driven rollers 62 to rotate, so that the steel pipe gradually passes through the position of the ring body 2 under the action of friction force for polishing, and the polished steel pipe is transported by the feeding mechanism 6 arranged on the concave frame 5 on the side of the ring body 2 away from the rotating ring 3, so as to realize automatic polishing of the steel pipe; When the steel pipe is conveyed through the ring body 2, the first electric push rod 71 is started to drive the first motor 72 to approach the steel pipe, so that the polishing wheel 73 contacts the outer wall of the steel pipe, and then the first motor 72 is started to drive the first rotating shaft 721 and the polishing wheel 73 to rotate, and the polishing wheel 73 polishes the outer wall of the steel pipe. During the polishing process, the second motor 41 is started to drive the second rotating shaft 411 and the gear 42 to rotate. When the gear 42 is meshed with the gear ring 31, the gear 42 drives the gear ring 31 and the rotating ring 3 to rotate, so that the polishing wheel 73 can move along the outer peripheral surface of the steel pipe to achieve the polishing work of the outer peripheral surface of the steel pipe; During the rotation of the ring gear 31 and the rotating ring 3, the second rotating shaft 411 will drive the rotating shaft 23 and the fan blades 231 to rotate through the second transmission assembly 24. During the rotation of the fan blades 231, an airflow will be formed in the blowing pipe 22 and blown into the blowing pipe 21. The airflow blown into the blowing pipe 21 is then ejected through the air nozzle 21 to spray and clean the polished end of the steel pipe passing through the ring body 2, thereby reducing the possibility of polishing residues adhering to the outer wall of the steel pipe, thereby reducing the trouble of manually cleaning the polishing residues on the outer wall of the steel pipe.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
