The invention discloses a cement pole erecting device. The cement pole erecting device is used for solving the problem of inconvenience in erecting cement poles in remote areas such as mountainous areas. The cement pole erecting device is characterized in that a lifting arm is arranged on the front side of a vehicle, a lifting cylinder is arranged between the lifting arm and the vehicle, a swing cylinder is hinged to the middle of the lifting arm, and a base is hinged to a free end of the lifting arm and is hinged to a piston rod of the swing cylinder; a mounting plate is fixed to a side of the base, a turntable is rotationally mounted on the mounting plate, and a first driving mechanism which can drive the turntable to rotate is arranged on the base. A support is fixed onto the turntable, and a cement pole clamping assembly is arranged on the support; second driving mechanisms are arranged in inner cavities of the support, conveying cylinders are arranged between the second driving mechanisms and the support, and rotatable conveying wheels are arranged on the second driving mechanisms. The cement pole erecting device has the advantages that the cement poles can be clamped, lifted, erected and inserted by the aid of the cement pole erecting device, various actions can be carried out by mechanical structures and driving components and are successively linked with one another, and accordingly the cement pole erecting device is high in work efficiency.
