The invention provides a lifting appliance and a lifting method for a ladle nozzle pocket block. The lifting appliance comprises a vertical shaft, a lifting ring, a supporting piece and a sliding piece, the supporting piece is coaxially fixed at the bottom end of the vertical shaft; the vertical shaft is coaxially sleeved with the sliding piece in a sliding mode, and the sliding piece can rotate around the central axis of the vertical shaft. A plurality of supporting legs capable of turning over up and down are uniformly distributed on the periphery of the sliding part in the circumferential direction; a plurality of first containing grooves capable of containing the supporting legs are evenly distributed in the periphery of the supporting piece in the circumferential direction. When the supporting leg is located in the first containing groove and the sliding piece slides to the lowest position, the horizontal distance from the bottom end of the supporting leg to the central axis of the vertical shaft is smaller than the minimum radius of an inner hole of the nozzle pocket block. When the supporting leg retreats from the first containing groove and the sliding piece slides to the lowest position, the horizontal distance from the bottom end of the supporting leg to the central axis of the vertical shaft is larger than the minimum radius of the inner hole of the nozzle pocket block. The lifting appliance is simple in structure and convenient to operate, the lifting appliance can be switched from the entering state to the clamping state only by enabling the supporting legs to enter or exit from the first containing grooves, and lifting stability is guaranteed.

    本发明提供一种钢包水口座砖的吊具及吊运方法,包括立轴、吊环、支撑件和滑动件;吊环固定在立轴顶端,支撑件同轴固定在立轴底端;滑动件同轴滑动套设于立轴上,且滑动件可绕立轴的中轴线旋转;滑动件的外周周向均布有多个可上下翻转的撑腿;支撑件外周周向均布有多个可容置撑腿的第一容置槽;当撑腿位于第一容置槽内,且滑动件滑动至最低位置时,撑腿底端至立轴中轴线的水平距离小于水口座砖内孔的最小半径;当撑腿退出第一容置槽,且滑动件滑动至最低位置时,撑腿底端至立轴中轴线的水平距离大于水口座砖内孔的最小半径;本发明装置结构简单,操作方便,只需使撑腿进入或退出第一容置槽即可将吊具从进入状态切换至卡紧状态,保证吊运平稳性。
