Large stepped incinerator grate overhauling and hoisting device and method

Abstract

The invention provides a large stepped incinerator grate overhauling and hoisting device and method. The large stepped incinerator grate overhauling and hoisting device comprises a supporting frame, asliding rail, an adjustable anti-skid base and a hoisting mechanism, wherein the sliding rail and the adjustable anti-skid base are connected with the supporting frame, the hoisting mechanism is connected with the sliding rail, the adjustable anti-skid base comprises a rotating wheel and an anti-skid bottom plate which are connected with each other, the bottom end of the supporting frame is connected with the rotating wheel through a fixing piece, the angle of the rotating wheel is adjusted according to the ground through an anti-skid bottom plate of the anti-skid base, the angle of the rotating wheel is fixed through the fixing piece of the supporting frame, the hoisting device is convenient to operate, the hoisting efficiency of an incinerator grate and a middle beam cover plate is improved, the base is provided with a rotary fixing corrugated anti-skid foot base, friction force is increased, the sliding danger is prevented from happening in the lifting process, and the purpose of safe lifting is achieved. The hoisting mechanism in the hoisting device can be flexibly hoisted by controlling the button of a handle.

Description

technical field [0001] The present disclosure relates to a large stepped incinerator grate inspection and lifting device and method. Background technique [0002] Overhaul of large stepped incinerator grate in environmental protection power plant involves flipping and hoisting of incinerator grate and middle beam cover plate. The existing grate inspection and hoisting method generally uses a simple gantry frame supported by bracket steel pipes lapped into a "herringbone" character for flipping hoisting. The construction site needs to spend a lot of labor to erect scaffolding in advance to make a gantry hanger, and place it in the middle of the incinerator grate. The joints of the beams are lined up, and it is inconvenient to overturn the cover plate for maintenance and cannot be moved. This method is cumbersome to prepare in the early stage, with many participants but low efficiency, which greatly increases the maintenance time; [0003] This method is cumbersome to prepare...

Problems solved by technology

The existing grate inspection and hoisting method generally uses a simple gantry frame supported by bracket steel pipes lapped into a "herringbone" character for flipping hoisting. The construction site needs to spend a lot of labor to erect scaffolding in advance to make a gantry hanger, and place it in the middle of the incinerator grate. The joints of the beams are lined up, and it is inconvenient to overturn the cover plate for maintenance and cannot be moved. This method is cumbersome to prepare in the early stage, with many participants but low efficiency, which greatly increases the maintenance time;

[0003] This method is cumbersome to prepare in the early stage, and there are many people involved. The hoisting device built by scaffolding needs manual hand chain hoists, which is prone to slipping during hoisting, the hoisting risk factor is large, and the construction efficiency is low.
