Assembly type electric pole mounting device and method

The invention provides an assembly type electric pole mounting device and method.The assembly type electric pole mounting device is provided with a mounting frame, and the mounting frame comprises a frame body, a hoisting device, a clamping device, a rotating assembly and a limiting assembly; the clamping device and the limiting assembly can restrain lateral movement of the electric pole pipe joint, so that the electric pole pipe joint and the frame body synchronously act, and the perpendicularity of the electric pole pipe joint is rapidly adjusted. The restrained electric pole pipe joint makes contact with the rotating assembly, the electric pole pipe joint obtains the rotating freedom degree around the pole shaft when the rotating assembly rotates, the pipe joint rotates along with rotation of the clamping device, and by controlling rotation of the pipe joint, the problem that a pipe joint fixing flange is difficult to align due to the fact that the pipe joint is difficult to rotate after being hoisted in a
