Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1-6, the utility model comprises a base 1, a rotary roller 2, a motor bracket 3, a motor moving plate 4, a motor 5 and a gear plate 6. As shown in fig. 6, the base 1 includes a bracket 1a3, two supporting seats 1a1 and two lifting plates 1a 2; two supporting seats 1a1 are fixedly arranged at two ends of the bracket 1a3 in parallel. The supporting seat 1a1 comprises two supporting plates 1a11 which are arranged in parallel, a V-shaped groove 1a12 is arranged in the middle of the supporting plate 1a11, and the V-shaped grooves 1a12 of the two supporting plates are coaxial. Two rotating rollers 2 are arranged between the two supporting plates, two rotating roller mounting holes a1 are correspondingly arranged on the two supporting plates 1a11 respectively, the rotating shaft of the rotating roller 2 is arranged in the rotating roller assembly mounting hole a1, and the two rotating rollers 2 are symmetrically arranged. The rotating shaft of the rotating roller wheel 2 extends out of the supporting plate positioned outside the base, and the extending part of the rotating shaft is of an outer hexagonal structure, so that the manual adjustment of the rotating roller wheel assembly 2 is facilitated. The cylindrical side surface of the rotating roller 2 is higher than the bottom surface of the V-shaped groove 1a12, so that the rotating roller 2 can be ensured to support the steel pipe.
