Abstract
The utility model discloses a kind of smelting furnace group compacting device of furnace door, comprise double leval jib, directive wheel and the guide wheel bracket being arranged on the fire door left and right sides, the guide wheel bracket of the every side of fire door comprises upper bracket and lower carriage, the guide wheel bracket of the every side of described fire door is also provided with a plate, the two ends of connecting plate respectively with described upper bracket, lower carriage is fixedly connected with, and suppending hole is provided with on the middle part of connecting plate, furnace binding shaped steel position above connecting plate is also provided with a fixed head, suppending hole on connecting plate is connected by chain with between fixed head.The utility model structure is simple; Adopt after said structure, packing and fire door can be made substantially not to rub, extend packing service life, then indirectly reduce labour intensity and enterprise's production cost of attendant; Decrease fire door to cause leaking fiery problem because of packing wearing and tearing, reduce fuel consumption, also extend service life of equipment.
Description
Technical field
The utility model relates to smelting furnace technical field, especially a kind of smelting furnace group compacting device of furnace door.
Background technology
Existing smelting furnace group fire door compressing structure mainly contains following three kinds.
The first adopts channel-section steel to make track, is elevated, in track lower end, channel-section steel rolled over the turning of 135 °, change direction, be affixed to fire door when fire door is declined by fire door directive wheel along track.But in laminating process, because packing has certain elasticity, cause fire door after packing contact fire door also to want slide downward, cause producing between fire door packing and fire door backplate rubbing, reduce the service life of packing.
The second is hydraulic lifting, cylinder-pressing, and this kind of mode adopts hydraulic lifting fire door, after fire door decline puts in place, adopt cylinder-pressing, fire door is moved in the horizontal direction, directly compress after such packing contacts with fire door, without the friction problem between packing and fire door, the packing life-span is longer.But because this kind of structural acessory is more, add the accessories such as Hydraulic Station, air compression station, cylinder more, cost is high and fault is many, and practical application is less.
The third is four-bar linkage structure, is also to use the widest a kind of compressing structure at present, and it compares first kind of way larger improvement, and track is a straight line, no longer bending, relies on fire door directive wheel to compress to the inside.But due to fire door decline put in place after, when doing circular motion with directive wheel central point, fire door is substantially in circular arc vertical tangent lines position, in fire door downwards " picture arc " closing process, packing is after touching fire door, because packing has certain elasticity, or can continue downwards and fire door fit to close to produce packing simultaneously and rub, cause packing still can be worn, there will be in actual applications leak fire situation, dangerous and waste fuel, need timing to packing carry out maintenances replacing, waste time and energy, increase enterprise's production cost.So, need badly a kind of compressing structure that can extend packing service life is provided.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned prior art, provides the smelting furnace group compacting device of furnace door that a kind of structure is simple, extend packing service life.
To achieve these goals, the technical solution adopted in the utility model is: a kind of smelting furnace group compacting device of furnace door, comprise double leval jib, directive wheel and the guide wheel bracket being arranged on the fire door left and right sides, the guide wheel bracket of the every side of fire door comprises upper bracket and lower carriage, it is characterized in that: the guide wheel bracket of the every side of described fire door is also provided with a plate, the two ends of connecting plate respectively with described upper bracket, lower carriage is fixedly connected with, and suppending hole is provided with on the middle part of connecting plate, furnace binding shaped steel position above connecting plate is also provided with a fixed head, suppending hole on connecting plate is connected by chain with between fixed head.
Further, one is also fixedly connected with between described chain and fixed head for the adjusting screw(rod) of adjusting chain length.
Further, the two ends of described connecting plate are welded with the middle part of described upper bracket, lower carriage respectively.
The beneficial effects of the utility model are: structure is simple, after adopting said structure, packing and fire door can be made substantially not to rub, and extend packing service life, then indirectly reduce labour intensity and enterprise's production cost of attendant.Specifically, after fire door declines and puts in place, with the tie point of chain top and fixed head for doing " circular arc " movement locus in the center of circle, until fit with fire door; Because this circular arc center of circle is positioned at fire door higher position, positive top and radius is several times as much as " circular arc " radius originally, the friction between packing and fire door can be reduced to greatest extent; Decrease fire door to cause leaking fiery problem because of packing wearing and tearing, reduce fuel consumption, also extend service life of equipment.
In addition, the utility model, owing to being the improvement made on the basis of original four-bar linkage structure, maintains original structure substantially, and change position is few, and improving cost is low, and can obtain good result, has good promotional value.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, 2, a kind of smelting furnace group of the utility model compacting device of furnace door, comprise double leval jib 1, be arranged on the guide wheel bracket 2 of the fire door left and right sides and directive wheel 4, the guide wheel bracket 2 of the every side of fire door comprises upper bracket and lower carriage.
The guide wheel bracket 2 of the every side of fire door is also provided with a plate 3, the two ends of connecting plate 3 are fixedly connected with upper bracket, lower carriage respectively, and suppending hole 5 is provided with on the middle part of connecting plate 3, the furnace binding shaped steel position above connecting plate 3 is also installed with a fixed head 8.Suppending hole 5 on connecting plate 3 is connected by chain 6 with between fixed head 8.An adjusting screw(rod) 7 is also fixedly connected with between chain 6 and fixed head 8, in actual use, can by the length of adjusting screw(rod) 7 adjusting chain 6.
In the present embodiment, above-mentioned fixed head 8 is welded on furnace binding shaped steel position.The two ends of above-mentioned connecting plate 3 are welded with the middle part of upper bracket 21, lower carriage 22 respectively.Certainly, the fixed form of fixed head 8 and connecting plate 3 is not only welding, also can be connected by other fixed form, as connected by fixed forms such as bolts.
Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or equivalently to replace, does not all depart from essence and the scope of technical solutions of the utility model.
