Description
The invention belongs to the blast-furnace technique field.
At present, some do not have in the material furnace roof blast furnace both at home and abroad, and distributor chute and cloth drive unit generally adopt connecting modes such as gooseneck boom formula top extension, for example Luxembourg and China Baogang.When need changing distributor chute, all be it to be suspended in midair with crane, observe loading position in the stove by the workman who stands in before the manhole, and meanwhile command the crane workman to operate crane, to mount and dismount.There is following shortcoming in this substitute mode:
1, because the distributor chute loading and unloading are to carry out in stove, therefore, lifting was observed and is commanded on safety of workers ground before furnace temperature must be reduced to and can make manhole;
2, situation of the loading and unloading and commander's crane workman make the charge and discharge operations difficulty greatly in the manual observation stove;
3, the replacing time is long.
The objective of the invention is, at above-mentioned shortcoming, provide a kind of device that loads and unloads bell-less charge-distributing chute on furnace top, to finish the replacing of distributor chute fast, easy, accurately.
Formation of the present invention is to comprise guiding road, support, linkage assembly and power set etc.Linkage assembly comprises rocking bar, crank, carriage etc.; Support is positioned on the guiding road and can moves forward and backward.One end of rocking bar and crank is hinged with support respectively, and the other end is hinged with carriage respectively, and power set is connected on crank or the rocking bar.As required, support can be moved to prescribed position in the stove, steering maneuver device program work in accordance with regulations, linkage assembly then can be finished actions such as loading, unloading.
Another formation of the present invention is to comprise slideway, support, support, linkage assembly, drive unit etc.Linkage assembly comprises crank, rocking bar, carriage, regulating rod etc., and drive unit comprises actuating arm, main shaft, driving crank, connecting rod, hydraulic ram etc.Crank bearing, spindle bearing, cylinder support are housed on the support, and its afterbody has a stopper slot.Slideway is fixed on the support.Support is positioned on the slideway and can moves forward and backward.Main shaft and spindle bearing, crank and crank bearing, hydraulic ram and cylinder support, the piston rod of actuating arm and hydraulic ram, rocking bar and main shaft, crank and rocking bar respectively with carriage, rocking bar and regulating rod, crank and drive crank respectively with the connecting rod two ends, be hinged.Also be connected to actuating arm on the main shaft and drive crank.Be connected to counterweight on the regulating rod, its lower end is enclosed within the stopper slot.On the vertical arm of carriage a pair of locating slot is arranged.As required, support can be moved to prescribed position in the stove, operating hydraulically operated oil cylinder program work in accordance with regulations, linkage assembly then can be finished the loading, unloading action.
Advantage of the present invention is:
1, can accurately put and finish the replacing operation in place, obviously shorten the replacing time;
2, easy to operate, safety;
3, be subjected to environmental influence little.
