Background technology
Blast furnace ironmaking is the Main Means that current China obtains the pig iron, and distributor is the key equipment of iron-smelting blast furnace furnace roof, realizes iron-smelting raw material spreading in furnace chamber, requires that cloth is even in circular flat domestic demand, must not occur piling up.The distributor complicated in mechanical structure that current domestic large blast furnace is applied, manufacturing accuracy requires higher, under particularly current energy-saving and emission-reduction require more and more higher overall situation, require blast furnace hot charging material loading, therefore the space of water-cooling swivel joint and water-cooled part must be reserved, the internal structure of original distributor can be more complicated, and weight also can increase further.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of structure simple blast-furnace distributor.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of blast-furnace top distributing device, comprise distributor housing, rotor, rotating machine, tilting motor, top rotating bearing, bottom rotating bearing and chute, chute hangs on the lower end of rotor by hanging gudgeon, rotating machine is installed on distributor housing, the rotary pinion of rotating machine output terminal engages with the outer ring of top rotating bearing, the outer ring of top rotating bearing is fixedly connected with rotor, and the inner ring of top rotating bearing is fixed on distributor housing; Tilting motor is installed on the side of distributor housing, bottom rotating bearing is fixed with in rotor bottom, inner ring and the rotor of bottom rotating bearing are fixed, and the outer ring of bottom rotating bearing is gear, and the pinion(gear) that fascinates of tilting motor output terminal engages with the outer ring of bottom rotating bearing; The outer ring of bottom rotating bearing is also connected with the master wheel that fascinates, rotor is installed intermeshing worm gear and worm screw, the axle head of worm screw is connected with worm shaft end gear, worm shaft end gear engages with the master wheel that fascinates, the inner ring of worm gear is fixedly connected with axis, the two ends of axis are provided with side direction gear, and side direction gear and the chute hung on gudgeon fascinate gears meshing.
In such scheme, all move and there is velocity contrast in inner ring and the outer ring of described lower rotating bearing, tilting motor is different from rotating machine rotating speed.
Implement blast-furnace top distributing device of the present invention, there is following beneficial effect:
1, the motion of fascinating of chute of the present invention is delivered to both sides by one group of worm gear device, be delivered to chute by side direction gear again to fascinate gear, for existing structure, when ensureing transmitting ratio, simplify internal structure, the height of distributor can be reduced further;
2, the present invention controls by the rotating speed of tilting motor and rotating machine the independently moving or the compound motion that realize chute, and eliminate epicyclic gearbox, structure is simpler.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the front view of blast-furnace top distributing device structural representation of the present invention;
Fig. 2 is the left view of blast-furnace top distributing device structural representation of the present invention;
Fig. 3 is the layout schematic diagram of train in blast-furnace top distributing device of the present invention.
Embodiment
In order to there be understanding clearly to technical characteristic of the present invention, object and effect, now contrast accompanying drawing and describe the specific embodiment of the present invention in detail.
As shown in Figure 1-Figure 3, blast-furnace top distributing device of the present invention comprises rotating machine 1, upper rotary supporting 2, rotary pinion 3, lower rotating bearing 4, the gudgeon 5 that fascinates, rotor 6, chute 7, chute fascinate gear 8, side direction gear 9, axis 10, worm gear 11, worm screw 12, worm shaft end gear 13, the master wheel 14 that fascinates, the pinion(gear) 15 that fascinates, tilting motor 16 and distributor housing 17.
The chute 7 of distributor hangs on the lower end of rotor 6 by the gudgeon 5 that fascinates, rotating machine 1 is installed on distributor housing 17, and the outer ring that rotary pinion 3 and the upper rotary of output terminal support 2 is engaged, and the outer ring of upper rotary supporting 2 is gear.Outer ring and the rotor 6 of upper rotary supporting 2 are fixed, and the inner ring of upper rotary supporting 2 is fixed on distributor housing 17, and rotating machine 1 makes rotor 6 rotate by driving upper rotary supporting 2, thus realizes the rotation of chute 7.Tilting motor 16 is installed on the side of distributor housing 17, lower rotating bearing 4 is fixed with in the bottom of rotor 6, the inner ring of lower rotating bearing 4 is fixedly connected with rotor 6, the outer ring of lower rotating bearing 4 is gear, and the pinion(gear) 15 that fascinates of tilting motor 16 output terminal engages with the outer ring of lower rotating bearing 4.The outer ring of lower rotating bearing 4 is also connected with the master wheel 14 that fascinates, and rotational circle cylindrical shell 6 is provided with worm gear structure.Worm screw 12 upper axial end is connected with worm shaft end gear 13, and worm gear 11 engages with worm screw 12, and is realized the transmission of moving by axis 10 with the side direction gear 9 of both sides.The inner ring of worm gear 12 is achieved a fixed connection by modes such as key are connected with axis 10.Side direction gear 9 and the chute hung on gudgeon 5 gear 8 that fascinates engages.
