The invention relates to a double-pull-rod wing-shaped lead lifting device which belongs to the technical field of power transmission lines. The technical solution of the double-pull-rod wing-shaped lead lifting device is characterized in that two lead screws which are parallel with each other are connected with a wing-shaped fixture (9) through a fixing plate (7); the lower end of each lead screw (1) is connected with an insulated pull rod (10); the other end of the insulated pull rod (10) is provided with a lead hook (12); the portion of each lead screw (1) above the fixing plate (7) is provided with a decompressor (4) and a ratchet (2); each ratchet (2) is connected with a corresponding lead screw (1) in threaded connection; the decompressor (4) comprises a decompressor upper cover (23) and a decompressor lower cover (24); the decompressor upper cover (23) is internally provided with a bead rack (28); steel beads (27) are arranged on the bead rack (28); and the decompressor upper cover (23) is connected with the decompressor lower cover (24) in threaded connection. The double-pull-rod wing-shaped lead lifting device has beneficial effects of simple structure, convenient use, high safety and high reliability. The double-pull-rod wing-shaped lead lifting device facilitates lifting of a large-cross-section lead and realizes live changing for a linear suspended insulator string.
