The invention relates to a lifting appliance for an inner cover. The lifting appliance comprises three first steel pipes, second steel pipes, steel wire rope lifting lug plates, a positioning ring, a connecting disc and a lifting ring, wherein the three first steel pipes are circumferentially and evenly distributed at 120 degrees, the second steel pipes are installed at the tail ends of the first steel pipes, and the steel wire rope lifting lug plates are installed at the bottoms of the second steel pipes; a square walking groove is formed in each steel wire rope lifting lug plate; the positioning ring is mounted on the inner sides of the lower ends of the three second steel pipes; and the connecting disc is installed in the middle of the tops of the three first steel pipes, and the lifting ring is of a U-shaped structure and installed in the middle of the top of the connecting disc. The lifting appliance has the beneficial effects that when the lifting appliance is used, the inner cover of an annealing furnace is arranged in the positioning ring, then lifting hooks connected with three steel wire ropes are arranged in the walking grooves of the steel wire rope lifting lug plates, and then the lifting hooks are arranged in the lifting ring to lift the inner cover of the annealing furnace, so that the gravity center of the inner cover of the annealing furnace is stable in the lifting process, and the inner cover of the annealing furnace is prevented from toppling and breaking.

    本发明涉及一种内罩吊具,包括第一钢管、第二钢管、钢丝绳吊耳板、定位圈、连接圆盘和起吊环,第一钢管包括三根且按120°圆周均匀分布,每根第一钢管末端均安装有第二钢管,每根第二钢管底部均安装有钢丝绳吊耳板,每块钢丝绳吊耳板上均设有方形走马槽,三根第二钢管下端内侧安装有定位圈;三根第一钢管顶部中间安装有连接圆盘,起吊环为“U”形结构且安装在连接圆盘顶部中间。本发明的有益效果是:使用时,将退火炉的内罩置于定位圈内,然后分别将连接三根钢丝绳的起吊钩置于钢丝绳吊耳板的走马槽内,然后将起重吊钩置于起吊环内将退火炉的内罩吊起,可使退火炉的内罩在吊起的过程中重心稳定,防止退火炉的内罩倾倒摔坏。
