Power transmission tower maintenance device

The invention discloses a transmission tower maintenance device which comprises four arc-shaped frames, every two of the four arc-shaped frames are arranged up and down, arc-shaped plates are fixedly connected to the positions, close to the front side and the rear side, of the corresponding sides of the arc-shaped frames correspondingly, open grooves are formed in the corresponding sides of the arc-shaped plates correspondingly, magnets are fixedly connected to inner cavities of the open grooves correspondingly, and the magnets are fixedly connected to the inner cavities of the open grooves correspondingly. Every two adjacent magnets are attached to each other, the arc-shaped frames can be arranged on the surface of the concrete electric pole in a sleeving mode through mutual cooperation of the arc-shaped frames, the arc-shaped fixing plates, the motors, threaded nails and other structures, when the high position of the concrete electric pole needs to be reinforced, other arc-shaped frames are stacked on the
