The lifting appliance comprises a transverse frame, two longitudinal frames are fixed to the side wall of the transverse frame, two vertical frames are fixed to the upper end of the transverse frame, a cross beam is fixed to the upper ends of the two vertical frames together, a fine adjustment box is fixed to the upper end of the cross beam, and a hanging lug is fixed to the upper end of the fine adjustment box. And a fine adjustment alignment mechanism is arranged in the fine adjustment box, rolling wheels are fixed to the bottoms of the transverse frame and the longitudinal frames, check blocks are fixed to the upper ends of the two longitudinal frames, and stabilizing mechanisms are arranged on the side walls of the two longitudinal frames. The clamping device has the advantages that the valve cover can move downwards through transfer of hydraulic oil in the sealing ring, the downward moving speed of the valve cover is low, and therefore the position of the valve cover can be adjusted more conveniently and accurately, the clamping accuracy and the clamping convenience degree are improved, when stopping is needed, only the sealing rod needs to be rotated, operation is easy and convenient, and the working efficiency is improved. The valve cover is accurately and conveniently mounted.
