Technical Field

[0001] The utility model relates to the technical field of agitator equipment, in particular to an adjustable correction assembly for a concentricity corrector. Background Technique

[0002] During the production, transportation and installation of steel pipes, concentricity deviation may occur due to various reasons. For example, during transportation and storage, steel pipes may be subject to mechanical impact or deformation, resulting in concentricity deviation. A concentricity corrector is a device used to adjust the concentricity of steel pipes to ensure safety and performance. When correcting, it is usually necessary to correct the concentricity of steel pipes of different specifications. Therefore, an adjustable correction assembly for a concentricity corrector is proposed, which has adjustable characteristics and can be adjusted correspondingly according to the specifications of steel pipes.

[0003] Chinese Utility Model Patent Publication No.: CN 211527301 U, discloses: A concentricity detection device for seamless steel pipes. In this concentricity detection device for seamless steel pipes, through the cooperation of bearings and a pressure seat, the steel pipe can closely adhere to the bearing and rotate stably and smoothly when it needs to rotate during concentricity detection; the positioning plate improves the stability of the position of the steel pipe each time it is placed, so that the measuring head of the set concentricity instrument can just enter the pipe orifice of the steel pipe, ensuring the detection accuracy and accuracy; the lifting mechanism is arranged on the pressure seat, making it quite easy and convenient to press and release the steel pipe. However, this concentricity detection device for seamless steel pipes can only detect steel pipes and cannot correct the concentricity of steel pipes. Summary of the Invention
