The invention relates to a fast lifting device for a neck water bag of a glass melting furnace. The fast lifting device is characterized in that the water bag (5) is matched with a pair of bearing blocks (6) arranged on a lifting platform in a connection manner, the water bag is connected with a worm wheel (8) which is matched with a worm (12) arranged on the lifting platform (2) in a connection manner, one end of the worm (12) is provided with a hand wheel (9), and the water bag can be driven to overturn by the hand wheel, the worm wheel and the worm. The fast lifting device has the advantages as follows: the water bag is lifted by turning over the water bag, although the travel of the lifting part is increased, the weight of the water bag to be lifted is greatly reduced; in the invention, the effieincy of an efficient worm gear mechanism can reach about 70%, so the overall efficiency of the lifting device is three times higher than that of a worm-wheel screw rod lifter; and the lifting device can complete primary water bag entering or exiting within 5-8 minutes only, thereby greatly shortening the operating time, and being beneficial to handling emergencies.
