Shield tunneling machine steel pipe mounting and lifting device

The invention discloses a shield tunneling machine steel pipe installing and lifting device which comprises a bottom plate, an upper plate and a lifting assembly, wherein the lifting assembly is arranged and installed between the bottom plate and the upper plate, a clamping assembly is connected and installed on the lifting assembly, and a steel pipe is clamped on the clamping assembly; and the clamping assembly comprises a clamping base, clamping blocks and adsorption assemblies, the adsorption assemblies are arranged on the clamping block, and the clamping blocks are installed on the clamping base. According to the device, the adjacent clamping blocks are hinged through connecting rods, so that a single group of clamping blocks has certain flexibility and can adapt to steel pipes with different diameters; when the adsorption assemblies on the clamping blocks are adsorbed on the steel pipes, a piston rod of a telescopic rod abuts against the steel pipe, and the stability in the clamping process is improved;
