Integral lifting device for high-rise long-span door type truss

The utility model relates to an integral lifting device for a high-rise long-span door type truss, which comprises through jacks, steel strands and an anchoring structure. The anchoring structure consists of an upper anchoring structure and a lower anchoring structure, the upper anchoring structure is fixed onto positioned truss brackets, the lower anchoring structure is fixed onto a lifted truss, the through jacks are fixed onto the upper side of the upper anchoring structure and symmetrically disposed on two sides of a positioned upper truss bracket, and the lifted truss is lifted to a position flush with the positioned upper truss bracket by the through jacks and the steel strands. A lifting unit realizes integral lifting while being monitored in a dynamic stress monitoring mode throughout the process, auxiliary measures of the lifting method only includes building an operating scaffold during surface splicing and an overhang scaffold at a lifting position, the integral lifting device requires less measure
