The invention discloses a lifting device for well lid maintenance. The lifting device comprises a moving frame, a first lifting mechanism, a support, a lifting arm and a clamping mechanism. A well lid can be moved to a designated position through the moving frame, and the first lifting mechanism drives the lifting arm to lift the well lid. The clamping mechanism comprises a first mounting plate, a second lifting mechanism fixedly arranged at the center of the first mounting plate, guide rods symmetrically arranged along the center of the first mounting plate, a connecting rod with one end being hinged to the guide rods and the other being hinged to the second lifting mechanism, and clamping blocks arranged at the other ends of the guide rods. Stable positioning and clamping of the well lid are achieved. The lifting device for well lid maintenance is high in lifting safety, stability and precision, the working efficiency is improved, and the labor intensity is relieved.
