Technical field
The present invention relates to steelmaking converter, particularly for the provision for disengagement of converter inclining gear wheel tangential keys, and tangential keys method for dismounting.
Background technology
The converter installation of steel-making is provided with tilting equipment, is used for driving converter to tilt, and pours out the molten steel of inside.Tilting equipment includes the gear wheel that fascinates, as it is shown in figure 1, be connected transmission by tangential keys 8 between gear wheel 91 with axle 92.
Tangential keys are made up of positioning key and load key, positioning key and load key are respectively provided with lozenges, when gear wheel 91 and axle 92 assemble, it is initially charged with positioning key, then load key it is pressed into by force, utilizing lozenges to make tangential keys swelling in keyway, the pulling force after above-mentioned swelling reaches more than 350 tons, and this causes that tangential keys dismounting operation is extremely difficult.
The common method dismantling tangential keys at present has, and is threaded hole, after being then charged into bolt, pulls out by force by means of power bolt on tangential keys, but is easily caused the sliding tooth of screw thread, is disassembled into power non-normally low.Also having and arrange draw-in groove on tangential keys and utilize pawl tool to hook draw-in groove and pull out, but the situation that pawl tool fracture or draw-in groove slip often occur, dismounting effect is also undesirable.
Summary of the invention
The technical problem to be solved is: provide tangential keys provision for disengagement and the method for dismounting of a kind of converter inclining gear wheel, has the higher power that is disassembled into and the simpler safety of unloading process.
The technical solution adopted for the present invention to solve the technical problems is:
The tangential keys provision for disengagement of converter inclining gear wheel, including T-shaped device body, it is top that device body is positioned at one end of T-shaped bottom, and the part being positioned at T-shaped top is wing tip, and the described wing tip side near top is provided with baffle plate.
Further, described device body being additionally provided with main gusset, main ribs plate runs through top and wing tip, and the wing tip of main gusset both sides is additionally provided with secondary gusset, and main ribs plate is parallel with top bearing of trend with secondary gusset bearing of trend；Described device body is steel plate.
The tangential keys method for dismounting of converter inclining gear wheel, adopts the tangential keys provision for disengagement of above-mentioned converter inclining gear wheel to carry out tangential keys dismounting, including the following steps that order carries out:
A, end, described top is welded on the load key outer end of tangential keys；
B, arranging two Separated oil jacks between gear wheel and provision for disengagement fascinating, one end of two Separated oil jacks is resisted against the gear wheel end face that fascinates, and the other end bears against two baffle plates in provision for disengagement；
C, startup Separated oil jack, promote provision for disengagement to be loaded into key pull-out, pull down loosening positioning key subsequently, and the dismounting of whole tangential keys is complete.
The invention has the beneficial effects as follows: the tangential keys provision for disengagement of above-mentioned converter inclining gear wheel and method for dismounting, the top of device is welded with load key outer end, hydraulic jack is utilized to promote provision for disengagement, load key is made to be drawn out, loosening positioning key can be pulled down subsequently, dismounting has higher success rate, and the simpler safety of unloading process.
Accompanying drawing explanation

Fig. 2 is the provision for disengagement schematic front view of the present invention；
Fig. 3 is the side schematic view during provision for disengagement use of the present invention；
In figure, accompanying drawing is labeled as: device body 1, top 11, wing tip 12, baffle plate 2, main gusset 3, secondary gusset 31, tangential keys 8, load key 81, positioning key 82, gear wheel 91, axle 92.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
The tangential keys provision for disengagement of converter inclining gear wheel, including T-shaped device body 1, it is top 11 that device body 1 is positioned at one end of T-shaped bottom, and the part being positioned at T-shaped top is wing tip 12, and the described wing tip 12 side near top 11 is provided with baffle plate 2.
As shown in Figure 2,3, device body 1 is T-shaped, and the one end being positioned at T-shaped bottom is top 11, and the part being positioned at T-shaped top is wing tip 12.As shown in Figure 1,3, top 11 for tangential keys 8 load key 81 end weld.
The wing tip 12 side near top 11 arranges baffle plate 2 for bearing the force of hydraulic jack.
Preferably, it is possible to be additionally provided with main gusset 3 on described device body 1, main ribs plate 3 runs through top 11 and wing tip 12, and the wing tip 12 of main gusset 3 both sides is additionally provided with secondary gusset 31, and main ribs plate 3 is parallel with top 11 bearing of trends with secondary gusset 31 bearing of trend.
As it is shown on figure 3, main gusset 3 and secondary gusset 31 are for strengthening the intensity of this provision for disengagement, the described preferred material of device body 1 is steel plate, and making end, top 11 is flat, it is simple to weld with load key 81 end.
This provision for disengagement using method, for instance it may be that adopt the tangential keys provision for disengagement of aforementioned converter inclining gear wheel to carry out tangential keys dismounting, including the following steps that order carries out:
A, end, described top 11 is welded on load key 81 outer end of tangential keys；
B, arranging two Separated oil jacks between gear wheel and provision for disengagement fascinating, one end of two Separated oil jacks is resisted against the gear wheel end face that fascinates, and the other end bears against two baffle plates 2 in provision for disengagement；
