The invention discloses a safety hoisting tool for large-sized pump bodies applied to petroleum transportation. The safety hoisting tool comprises a balance plate and pothooks, wherein a weighting block is arranged at the upper end of the middle part of the balance plate; a hoisting ring is arranged at the upper end of the weighting block; the balance plate is provided with clamping notches at the two ends of the weighting block along the axial direction; the pothooks are arranged in the clamping notches of the two ends; each pothook comprises a fixture block clamped at the upper end of the clamping notch and a pothook rod connected to the fixture block and passing through the clamping notch; a locknut is sleeved on the pothook rod; a thread segment matched with the locknut is arranged at the upper end of the pothook rod; and pothook bodies are arranged at the lower ends of the pothook rods. The safety hoisting tool has the beneficial effects that the interval between the pothooks can be adjusted according to the pump bodies of different sizes, thereby meeting the hoisting of the pump bodies of different sizes, after hoisting, the pothooks are locked through the locknuts, do not shift and are safe for the pump bodies, and the safety hoisting tool is stable in structure on the whole during hoisting, does not cause the rotation of the pump bodies and is good in hoisting safety and stability.
