The present invention relates to the technical field of engineering machines, in particular to a gantry crane (1) lightning protection device, a machine and a use method thereof. The gantry crane (1) lightning protection device includes:a rotatable rod (2) structure, including a rotatable rod (2), wherein the rotatable rod (2) is fitted inside an insulating sleeve (13) of a gantry crane (1); an umbrella net structure (11), including a guide sleeve (3) threadedly and rotatably connected with the rotatable rod (2) in a sleeving manner, wherein the guide sleeve (3) is arranged on an outer circumference of the rotatable rod (2), conductive longitudinal rods (4) are arranged at intervals on the guide sleeve (3), and conductive cross-rings are arranged at intervals and around the conductive longitudinal rods (4);the radii of the conductive cross-rings are different from each other so that the heights of positions are also different from each other when the umbrella net structure (11) is unfolded;and a conductive structure, including a conductive wire (14) and a grounding carbon rod (15), wherein one end of the conductive wire (14) is fixedly connected with the rotatable rod (2), the other end thereof is connected with the grounding carbon rod (15), and in a lightning protection state, the conductive longitudinal rods (4) extend out of the insulating sleeve (13), the conductive cross-rings unfold along the circumferential direction of the conductive longitudinal rods (4) into an umbrella shape, and the conductive cross-rings and the conductive longitudinal rods (4) together form an umbrella-shaped structure, so that the gantry crane (1) is shielded from lightning, wherein lightning is transmitted to the conductive wire (14) by the rotatable rod (2), and finally transmitted to the ground by the conductive wire (14) via the grounding carbon rod (15). The invention solves the problem that the gantry crane (1) can not be covered by the lightning rod, and as a result, the protection effect is affected.
