Detailed ways

As shown in Figures 1-6, a pipeline outer anti-corrosion insulating layer remover according to the utility model includes a positioning mechanism and a knife feeding mechanism arranged in the pipeline.

As shown in Figures 1-6, the positioning mechanism includes a T-shaped platform 9, a wedge block 8, a tapered cylinder 7, a central tube 5, a push nut 10, and a push screw 6. The central pipe 5 is arranged coaxially with the pipeline. Conical cylinder 7 is provided with a tapered groove, wedge-shaped block 8 is provided with a through hole, wedge-shaped block 8 can slide in the groove, central tube 5 is provided with external threads, and conical cylinder 7 and central tube 5 are fixed Together, the inside of the tapered cylinder 7 and the central tube 5 is provided with a push screw 6 , the push screw 6 is threadedly connected with the push nut 10 , and the finger end of the push nut 10 passes through the through hole of the wedge block 8 .

Preferably, the push screw 6 can rotate in the conical barrel 7 to drive the push nut 10 to move axially along the push screw 6 , and then drive the wedge block 8 to slide in the groove of the conical barrel 7 . Preferably, the number of wedge blocks 8 is more than three, and they are evenly arranged along the surface of the tapered cylinder 7 .
