<p>The present invention provides a double rotating-type coating device for coating an inner wall of a pipe, comprising a main frame having a mounting space inside and having an opening on both walls; a rotation shaft installed in a rotatable way on the main frame and both ends of the rotating shaft go through the opening at both sides of the main frame so as to project outside; a drive motor installed in the mounting space inside the main frame and providing a driving force for rotation of the rotation shaft; two clamping parts comprising the fixed-side clamps that are fixedly installed at both ends of the rotation shaft, and the two moving-side clamps that are positioned so as to face the respective fixed-side clamps and installed to be movable toward the respective fixed-side clamps; two cylinders capable of horizontal movement of the respective moving-side clamps; and, two connection frame parts installed so as to face each other, which connect the fixed-side clamps constituting the respective clamping parts, and the cylinders for horizontal movement so as to be rotatable. The present invention is capable of achieving structural stability and an improvement in productivity by minimizing the moment applied to the rotation shaft according to the phenomenon of displacement weight caused by the coating operation of the inner pipe made of heavy object.</p> |
