The invention belongs to the technical field of lifting, and particularly relates to an anti-misoperation type lifting appliance emergency disengaging device. The anti-misoperation type lifting appliance emergency disengaging device comprises a pin shaft inserting and emergency disengaging mechanism and an anti-misoperation mechanism, and the pin shaft inserting and emergency disengaging mechanism comprises a pull rod bearing seat, steel wire rope set sleeves, upper pulley supports, upper pulleys, lower pulley supports, lower pulleys, pin penetrating seat returning springs, lifting appliance pin shafts, pull rods, a friction wheel, a switch chain wheel and a switch chain; The steel wire rope set sleeves, the upper pulley supports, the upper pulleys, the lower pulley supports, the lower pulleys, the pin penetrating seat returning springs, the lifting appliance pin shafts and the pull rods are arranged on the left side and the right side with the pull rod bearing seats as the symmetric center respectively; and the anti-misoperation mechanism comprises a chain wheel spiral support, an enabling chain wheel, an enabling chain and an enabling chain wheel return spring. A crane and a hoisted object can be quickly separated under an emergency condition, and meanwhile, the hoisted object can be quickly matched with the lifting hook during re-hoisting and can be prevented from being accidentally separated due to human errors.
