The invention discloses a flexible graphite anti-thunder grounding wire conveying device and relates to the technical field of flexible graphite anti-thunder grounding wire processing. The flexible graphite anti-thunder grounding wire conveying device comprises a left base, a right base, a supporting column I, a supporting column II, a screw rod, a first cross rod, a hand wheel, a second cross rod, a nut, a first rotary shaft, a conveyor belt, a second rotary shaft, a supporting rod I, a supporting rod II and guide rolls. The flexible graphite anti-thunder grounding wire conveying device is simple in structure, fast and convenient to operate, capable of adjusting the conveying distance through a driving device, also capable of tensioning the conveyor belt, capable of implementing up-down adjustment through the hand wheel and suitable for meeting different requirements for conveying graphite grounding wires. Meanwhile, when the conveying device is not in use, the right base can be driven to slide to the left base through the driving device. The flexible graphite anti-thunder grounding wire conveying device is small in occupied space and convenient to store and maintain.
