The utility model discloses a crown block lifting appliance for pickling steel pipes, which comprises a balancing device, a cross beam and a plurality of lifting hooks, wherein the balancing device comprises two first balancing plates and two second balancing plates, a first rotating shaft is installed on the upper end of each first balancing plate, the lower end of each first balancing plate is hinged with the upper ends of the second balancing plates via second rotating shafts, included angles are formed between the first balancing plates and the second balancing plates, the lower end of each second balancing plate is hinged with the top part of the cross beam via a third rotating shaft, a plurality of hooks are arranged on the bottom part of the cross beam, and one lifting hook is suspended on each hook. The crown block lifting appliance for pickling steel pipes disclosed by the utility model has the advantages of having a simple structure, avoiding the swing of the steel pipes, avoiding the splash of acid liquor, and reducing the acid liquor waste and the environmental pollution; the unhooking and hooking problems can be automatically realized in the case of groove feeding and groove discharging, thereby improving the utilization rate of the crown block and improving the pickling efficiency of the steel pipes. The gradient of the cross beam is adjusted by a cable wire so as to keep the stability of the steel pipes and incline the steel pipes.
