Example, as shown in fig. 1 to 5, a steel pipe rotating mechanism includes a left support frame 1 and a right support frame 2, the two support frames 1 and 2 are freely separated support frames, position adjustment can be performed independently, and steel pipes m with different sizes can be positioned, the axial direction of the steel pipe m is in the left and right directions, specifically, a left steel pipe lifting roller group a for lifting the left end portion of the steel pipe upwards is installed on the left support frame 1, the left steel pipe lifting roller group a includes two rollers arranged at intervals in the front and back direction and used for the left half portion of the steel pipe in the axial direction in the left and right directions, namely a left front roller a1 and a left back roller a2, the interval between the left front roller a1 and the left back roller a2 cannot exceed the diameter of the steel pipe to be processed, so that the steel pipe placed at the interval between the left front roller a1 and the left back roller a2 cannot fall down and can also be supported by the two rollers, however, the design of the interval between the left front roller a1 and the left rear roller a2 can allow a part of the bottom of the steel tube to enter, so that the center of gravity of the steel tube can be better located between the left front roller a1 and the left rear roller a2, the left front roller a1 and the left rear roller a2 can also form two better supporting points at the front lower part and the rear lower part of the left side of the steel tube to support the steel tube, and it is mentioned here that the left steel tube lifting roller group a supports the left end part of the steel tube, it can be understood that the left steel tube lifting roller group a is arranged at the left half part in the axial direction of the steel tube, the left steel tube lifting roller group a is located between the left end of the steel tube and the center of the steel tube, that is, when in use, the left steel tube lifting roller group a is close to the left end of the steel tube, but keeps a left-right interval with the left end of the steel tube as much as possible, on the one hand, the design can better support the left half part of the steel tube from the bottom to the top, on the other hand, when the end is polished, the influence and the interference of tip can not cause, on the one hand, can be better to the stability of supporting the steel pipe, through the symmetrical structure in right side, support about being divided into the steel pipe about the three-section carries on in other words, can also reduce the influence that axial deviation brought. Therefore, according to the aforementioned design concept, the right side needs to be a corresponding supporting structure, that is, the right supporting frame 2 is provided with a right steel tube lifting roller set b for upwards supporting the right end part of the steel tube, the right steel tube lifting roller set b comprises two rollers which are arranged at intervals in the front-back direction and axially used along the right half part of the steel tube in the left-right direction, the two rollers are respectively a right front roller b1 and a right rear roller b2, the positions of the two rollers are opposite to the left front roller a1 and the left rear roller a2 in the left-right direction, and the two rollers can be designed in a symmetrical shape.
