The invention discloses an automatic electric pole erecting device. The automatic electric pole erecting device structurally comprises a first auxiliary rod, a second auxiliary rod, a main rod, a telescopic rod, a connecting sleeve, a fixing bottom plate, a multi-gear wire stranding device, a hoisting oil wire, an electric pole, a top force bearing plate, a connecting hanging ring, a hanger, a connecting piece, a fixed pulley frame and a fixed pulley. The first auxiliary rod is arranged on the rear right portion of the main rod, and the second auxiliary rod is arranged on the rear left portionof the main rod and is symmetrical with the first auxiliary rod. The automatic electric pole erecting device has the beneficial effects that the multi-gear wire stranding device is arranged, according to the actual condition of electric pole hoisting erection, the hoisting erection speed of the electric pole can be freely controlled by changing the gears, and thus the effects that in preliminaryhoisting erection, the electric pole is erected in a hoisted mode at the first gear of the low speed to test whether the automatic electric pole erecting device can bear the weight of the electric pole or not so as to protect the device and ensure the safety of constructers, in the hoisting erection medium-term, the electric pole is erected in the hoisted at the speeds of the second gear and the third gear to improve the work efficiency, and when hoisting erection is about to be finished, the electric pole is erected in the hoisted accurately at the speed of the first gear to be vertical so asto improve the work accuracy are achieved.
