Transformer installation lifting device and matched construction method

The invention relates to the technical field of power transformer installation, in particular to a transformer installation lifting device and a matched construction method. The transformer installation lifting device comprises a bearing seat with a plurality of universal wheel sets at the bottom, a lifting seat used for placing an assembled transformer assembly is arranged at the top of the bearing seat, a jacking lifting cylinder set is fixedly installed at the bottom of the lifting seat, the bottom of the jacking lifting cylinder set is fixedly installed on the bearing seat, and an opposite-pull locking mechanism used for controlling the two ends of an installation frame of the transformer assembly to be automatically locked is arranged at the top of the lifting seat. When the transformer installation lifting device is used for high-altitude installation of a transformer, the transformer is pre-assembled on the ground and then is installed high above the ground; the high-altitude operation steps and the hi
