The invention discloses an automatic pole climbing device with an operating arm. The automatic pole climbing device is used for pole climbing work through an electric pole and comprises a frame, a pole climbing unit and an operating arm posture adjusting unit. The frame comprises a main frame, a first side frame and a second side frame. The pole climbing unit comprises a clamping driving mechanism, a pole climbing driving mechanism and a positioning mechanism, wherein the clamping driving mechanism is fixed to the lateral side of the main frame and located between the first side frame and thesecond side frame, the pole climbing driving mechanism is arranged at the execution end of the clamping driving mechanism, and the positioning mechanism is movably connected to the end portion of theframe. The pole climbing driving mechanism is used for up-and-down moving of the pole climbing device on the electric pole after clamping. The operating arm posture adjusting unit comprises an operating arm positioning mechanism fixed to the outer side surface of the main frame and an operating arm clamping mechanism arranged at the execution end of the operating arm positioning mechanism. The operating arm clamping mechanism is used for clamping and posture adjusting of the operating arm. By means of the automatic pole climbing device, rapid clamping and automatic climbing on the electric pole and the flexible adjustment of the posture after clamping of the operating arm can be realized, operation like electric power overhaul is facilitated, and the practicability is high.
