The invention discloses workpiece quick cooling equipment for hot dip galvanizing and belongs to the field of hot dip galvanizing. The equipment comprises a base, wherein rollers are fixedly mounted at the bottom of the base, a transverse plate is fixedly connected to the side face of the base, an adjustment screw is arranged inside the transverse plate in a threaded and sleeved mode, an antiskiddisk is fixedly connected to the bottom end of the adjustment screw, a supporting sleeve is fixedly connected to the top of the base, and an adjustment rod is arranged inside the supporting sleeve ina movably sleeved mode. According to the workpiece quick cooling equipment for hot dip galvanizing, through the arrangement of a transmission shaft, a transmission motor, a transmission wheel, a conveying belt, an air conveying sleeve, an air inlet pipe, an air valve and an air outlet cover, in the cooling process of a hot dip galvanizing workpiece, cold air can be conveniently adopted to convey and cool the hot dip galvanizing workpiece, the problem that water resources are prone to waste in the traditional cooling mode of soaking in cold water is avoided, meanwhile the cooling speed of the hot dip galvanizing workpiece is increased, and therefore the working efficiency of hot dip galvanizing workpiece cooling is improved.
