Abstract
Disclosed is an adjustable roller carrier, comprising a roller carrier base (1), rollers (2) and a motor speed reducing driver, wherein both ends of the roller carrier base are each articulated with a roller bearing (3) and a roller carrier hydraulic jack (5), with the roller carrier hydraulic jack (5) being articulated with the roller bearing (3) and the roller (2) being mounted on the roller bearing. The roller carrier hydraulic jack and a hydraulic pump station thereof, and an electromagnetic valve are all placed inside a hollow roller carrier support so that not only the height and the center-to-center distance of the rollers are adjustable, but also the adjustable roller carrier has the advantages of being integrally compact in structure, and small in terms of occupied space. The adjustable roller carrier enables the steel pipe to rotate in a narrow space, can be fast lifted, and transported by railway. The adjustable roller carrier is convenient to operate and has high safety.
