Abstract

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.

Description

technical field [0001] The invention relates to the technical field of well cover maintenance, in particular to a lifting device for well cover maintenance. Background technique [0002] According to the requirements for cable line maintenance work, the cable inspection manhole cover needs to be lifted and moved during the cable line inspection work to inspect the equipment and facilities in the cable trench. Usually, the method of lifting and moving the well cover is that the operator holds a long operating rod with a hook, extends the hook of the operating rod into the lifting hole of the manhole cover and hangs it firmly, and lifts the manhole cover by lifting the operating rod with both hands, which is labor-intensive. Due to the large weight difference of the cable maintenance manhole cover, some manhole covers are thicker and heavy, requiring two people to lift and move, which consumes manpower, and because sediment is easy to accumulate between the manhole cover and t...
