Abstract

The utility model provides in a kind of chimney urceolus less in space and Steel Inner Core of Chimney is carried out the Steel Inner Core of Chimney lifting mounting device for flue-gas desulfurizing engineering that promotes.It is the hydraulic rockshaft of installation three or more synchronization lifting above the inwall of reinforced concrete structure chimney urceolus, and hydraulic rockshaft is evenly arranged in the circumference of chimney urceolus; Each hydraulic rockshaft is connected with the lower suspension centre being fixed on Steel Inner Core of Chimney outer wall by steel strand; Each lower suspension centre is positioned at immediately below a hydraulic rockshaft, and the steel strand be connected between hydraulic rockshaft and lower suspension centre are in vertical state.

Description

For the Steel Inner Core of Chimney lifting mounting device of flue-gas desulfurizing engineering
Technical field
The utility model relates to a kind of for Steel Inner Core of Chimney being arranged in chimney urceolus the device that Steel Inner Core of Chimney promotes.
Background technology
The chimney of flue-gas desulfurizing engineering comprises reinforced concrete structure chimney urceolus and Steel Inner Core of Chimney.Chimney urceolus is general first constructed, then installs Steel Inner Core of Chimney in chimney urceolus.Because the general diameter of Steel Inner Core of Chimney large (about 7m), highly high (more than 120m), weight are large, the space mounting Steel Inner Core of Chimney how in limited chimney urceolus is a problem.
Summary of the invention
The purpose of this utility model is to provide in a kind of chimney urceolus less in space carries out Steel Inner Core of Chimney the Steel Inner Core of Chimney lifting mounting device for flue-gas desulfurizing engineering that promotes.
Steel Inner Core of Chimney lifting mounting device for flue-gas desulfurizing engineering described in the utility model, above the inwall of reinforced concrete structure chimney urceolus, install the hydraulic rockshaft of more than three synchronization liftings, hydraulic rockshaft is evenly arranged in the circumference of chimney urceolus; Each hydraulic rockshaft is connected with the lower suspension centre being fixed on Steel Inner Core of Chimney outer wall by steel strand; Each lower suspension centre is positioned at immediately below a hydraulic rockshaft, and the steel strand be connected between hydraulic rockshaft and lower suspension centre are in vertical state.
The beneficial effects of the utility model: the utility model adopts the hydraulic rockshaft that volume is little, hoisting capacity is large, be arranged on the inwall of chimney urceolus, steel strand are connected with the lower suspension centre be fixed on Steel Inner Core of Chimney outer wall, by the synchronization action of multiple hydraulic rockshaft, the rising of steady drive Steel Inner Core of Chimney in chimney urceolus, achieves major diameter, heavy weight Steel Inner Core of Chimney erection & lift in finite space with less cost.
The above-mentioned Steel Inner Core of Chimney lifting mounting device for flue-gas desulfurizing engineering, Steel Inner Core of Chimney is welded by multistage at axis direction, and every section of Steel Inner Core of Chimney is welded by multi-disc curved plate in circumferential direction; Platform for lining multi-disc curved plate being welded into one section of Steel Inner Core of Chimney is provided with in the central lower of chimney urceolus.
Because general Steel Inner Core of Chimney diameter is large, the length of axial direction long (highly large), be made into overall after body cannot transport, therefore Steel Inner Core of Chimney can only be divided into several sections at axial direction in making factory, every section of Steel Inner Core of Chimney is made up of multi-disc curved plate.After each curved plate is transported to scene.After platform for lining in chimney urceolus is grouping and is welded into single hop, entirety carries out lifting upside-down mounting again.
1st section of Steel Inner Core of Chimney and first section of cylinder assembled time, every sheet steel inner cylinder is winched on platform for lining.After the 1st section of assembled welding of Steel Inner Core of Chimney, its stack shell welds interim hanger, then promoting to hang on hanger with chain block after the 1st section of Steel Inner Core of Chimney puts in place winches on platform for lining by the curved plate of the composition the 2nd section of Steel Inner Core of Chimney, assembled welding completes the 2nd section of Steel Inner Core of Chimney, again the 2nd section of steel inner cylinder is docked with the 1st section of Steel Inner Core of Chimney and weld, by that analogy.Often complete one section of Steel Inner Core of Chimney and on its stack shell, namely weld interim hanger in order to lift hypomere stack shell, by clean for interim hanger cutting polishing after having lifted.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of lifting state of the present utility model;
Fig. 2 is the birds-eye view of platform for lining.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Steel Inner Core of Chimney lifting mounting device for flue-gas desulfurizing engineering shown in Figure 1, lifting platform 11 is fixed with above the inwall of reinforced concrete structure chimney urceolus 1, lifting platform 11 is installed the hydraulic rockshaft 2 of six synchronization liftings, and hydraulic rockshaft is evenly arranged in the circumference of chimney urceolus.Steel Inner Core of Chimney 4 outer wall fixes six lower suspension centres 5.Each lower suspension centre is positioned at immediately below a hydraulic rockshaft, each hydraulic rockshaft 2 by steel strand 3 with immediately below lower suspension centre 5 be connected.The steel strand 3 be connected between hydraulic rockshaft and lower suspension centre are in vertical state; The hydraulic rockshaft of synchronization lifting drives Steel Inner Core of Chimney lifting by steel strand.
Steel Inner Core of Chimney 4 is welded by multistage at axis direction, and every section of Steel Inner Core of Chimney 41 is welded by multi-disc curved plate 411 in circumferential direction.
See Fig. 2, be provided with the platform for lining 6 multi-disc curved plate being welded into one section of Steel Inner Core of Chimney in the central lower of chimney urceolus 1.Platform for lining 6 mainly contains platform girder 61 and platform secondary beam 62 is welded, and platform girder 61 adopts shaped steel H200*200*8*12, and platform secondary beam 62 adopts shaped steel L100*10.
