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.

Embodiment 1

[0021] like figure 1 As shown, the present disclosure provides a large-scale stepped incinerator grate maintenance lifting device, including a support frame, a slide rail connected with the support frame and an adjustable anti-skid base, and a lifting mechanism connected with the slide rail; the adjustable anti-skid base includes The rotating wheels and the non-slip bottom plate are connected with each other, and the bottom end of the supporting frame is connected with the rotating wheels through a fixing piece.

[0022] Further, the support frame includes at least two sets of support rod groups, each set of support rod groups includes two support rod telescopic tubes arranged symmetrically, the two support rod telescopic tubes are connected by fixed tie rods, and the two ends of the fixed tie rods are respectively fixed on two One end of the slide rail is connected to the top of one set of support rods, and the other end is connected to the top of the other set of support rod...

Embodiment 2

[0033] The disclosed device includes an electric lifting device, four supporting steel pipes, and a horizontal sliding track. One end of the supporting steel pipe and the horizontal sliding track is connected by an angle adjustment gear, and the supporting steel pipe can rotate around the horizontal sliding track; the lifting device is fixed on a horizontal In the sliding track, limit blocks are set at both ends; a fixed pull rod is set between two supporting steel pipes on one side, and the two ends of the pull rod are respectively fixed on the two supporting steel pipes, and the base of the supporting steel pipe is provided with a rotation angle wheel with a fixer And the corrugated feet can make it suitable for different heights and slopes and the support steel pipe is stable when it is supported by the "herringbone".

[0034] This kind of lifting device is used for hoisting the grate of the incinerator and the cover plate of the middle beam. In order to improve the lifting ...

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...
