Quick well lid lifting device for municipal engineering

The utility model relates to the technical field of municipal engineering, and discloses a quick well lid lifting device for municipal engineering, a bottom plate is fixedly connected to the bottom of a fixing frame, an extraction hole is formed in the center of the bottom plate, universal wheels are fixedly connected to the four corners of the bottom of the bottom plate, and a lifting mechanism is fixedly connected to the middle of the fixing frame. The bottom of the lifting mechanism is fixedly connected with an adjusting and fixing mechanism. According to the quick well lid lifting device for municipal engineering, a bidirectional threaded rod is rotated by adjusting a hexagonal block according to the distance between two through holes for lifting a well lid, so that sliding blocks are close to or far away from each other on sliding rods under the cooperation of moving blocks, and hooks can be aligned to the through holes of the well lid; when the manhole cover is lifted, the transverse pin is turned out o
