ツク装置。[Claims for Utility Model Registration] An annular rotating body that surrounds a casing tube and is rotationally driven by a motor is rotatably supported on a horizontally supported lifting frame, and the rotating body and the casing tube are brought into contact with and separated from each other. In a rotary chucking device equipped with a chuck device, the chuck device connects a support frame to the elevating frame so as to be movable up and down by a chuck cylinder, and a rotary frame vertically opposed to the rotary body is rotatably connected to the support frame. A main working fluid cylinder with a protruding ram and a driven fluid cylinder having a larger diameter than the main working fluid cylinder with a protruding ram having a chuck member at the tip can be interlocked by connecting the inner chambers of both cylinders with a fluid circuit. In a fluid system in which one of the driving cylinders is mounted so that its ram is moved forward and backward by the lifting and lowering of the rotating frame by the chuck cylinder, the other driven cylinder is mounted on the rotating body, and its chuck member is moved toward and away from the casing tube. A casing chuck device for rotary tubing equipment that is fixed so that it can move forward and backward in the radial direction.
