The invention discloses a portable ground lead winding device, and mainly relates to the field of power construction equipment. The portable ground lead winding device comprises a U-shaped base. A cover plate is arranged at an opening of the base and provided with penetrating-out holes. Lifting rods are arranged in the base and provided with first connecting rods. A second connecting rod is hingedto each first connecting rod. Each first connecting rod and the corresponding second connecting rod are both matched with the corresponding penetrating-out hole. The ends, away from the first connecting rods, of the second connecting rods upwards stretch out of the penetrating-out holes. A rotating shaft is arranged on each second connecting rod and sleeved with a lead winding shell. A groove isformed in each lead winding shell. An upper lead stop plate is arranged on each rotating shaft. Limiting grooves are formed in the cover plate. The distance between the limiting grooves and the penetrating-out holes is matched with the length of the positions between the second connecting rods and the upper lead stop plates. The upper lead stop plates can be placed in the limiting grooves. The portable ground lead winding device has the beneficial effects that before the climbing process, workers do not need to move a ground lead out of the lead winding device in advance, the ground lead is not prone to being locked on the lead winding device, great convenience is achieved, construction efficiency is improved, and the ground lead can be wound around the lead winding device quite conveniently.
