Embodiment
Below in conjunction with accompanying drawing and embodiments of the invention, distributor of the present invention is described in further detail.
Fig. 1 is the enclosed Water-cooling blast furnace top distributor structural representation that the present invention is based on quick changing oil cylinder, and as shown in Figure 1, the essentially consist of this distributor, comprising: lifting driven unit 1 (amount to three, be uniformly distributed); Upper rotary supporting 2; Lower rotating bearing 3; Slip box circle 4; Distributor shell 5; Rotor 6; Connecting rod 7; Chute 8; Bottom enclosed aqueous cold plate 9; Suspension assembly 10; Central throat tube 11; Inner enclosed water wall 12; Rotary drive assembly 13.
Please refer to Fig. 1, the rotary drive assembly 13 of this distributor is using reducing motor as drive member.Distributor shell 5 is installed on blast furnace roof steel ring, and its medullary ray overlaps with blast furnace medullary ray.Rotary drive assembly 13 complete installations are on the top cover of distributor shell 5, pinion(gear) is installed on the output shaft of rotary drive assembly 13 to be engaged with the master wheel of upper rotary supporting 2, upper rotary supports the top cover of 2 inner rings and distributor shell 5 and fixes, and outer ring is connected with rotor 6; Lifting driven unit 1 is on totally three uniform top covers that are fixed on distributor shell 5, lifting driven unit 1 is connected with lower rotating bearing 3 outer rings by threaded rod, the inner ring of lower rotating bearing 3 is connected with slip box circle 4, slip box circle 4 is connected with suspension assembly 10 by connecting rod 7, and suspension assembly is installed on the bearing support of rotor 6.Suspension assembly is for fixed chute 8.Bottom enclosed aqueous cold plate 9 is arranged on the base plate of distributor shell 5.Inner enclosed water wall 12 lifts on the top cover of distributor shell 5.
Its principle of work is as follows: lifting driven unit 1 drives slip box circle 4 to pump along rotor 6 axis directions, and this moves through connecting rod 7 and fascinates together with driving chute 8 with the connecting rod crank winding machine suspension assembly 10 of two swing arms composition in suspension assembly 10; Rotary drive assembly 13 rotates rotor 6 by geartransmission, and rotor 6 top chocks also drive suspension assembly 10 and chute 8 to rotate, by the combination of different rotations and the mode of fascinating, can realize neatly the various distributing modes such as annular, fan-shaped and spiral.
Fig. 2 is the structural representation of lifting driven unit shown in Fig. 1, and as shown in Figure 2, this lifting driven unit is mainly made up of set nut 14, inner link 15, hoist cylinder 16, articulated linkage 17, threaded rod 18 and flexible pipe 19.These inner link 15 one end are the hinged head that hangs, and the other end is screw thread, and hole is opened in inside.Hoist cylinder 16 is opened two rod standard oil cylinders in hole for piston rod.Inner link 15 is fixed by set nut behind the hole on hoist cylinder piston rod, and inner link 15 is hinged by articulated linkage 17 and threaded rod 18, and whole lifting driven unit is connected with the outer ring of lower rotating bearing by threaded rod 18.
Compared with the distributors such as this distributor and the most frequently used both at home and abroad planet differential distributor, have simple in structure, operate steadily, be convenient to safeguard and the feature such as with low cost.With respect to the hydraulic oil cylinder driving distributor of domestic appearance, this distributor adopts the oil cylinder lifting drives structure with quick change function, only need to unclamp set nut 14 on lifting driven unit 1 and the installation standing bolt of oil cylinder itself, can realize the quick-replaceable of hoist cylinder 16, compared with existing hydraulic oil cylinder driving formula distributor, greatly dwindle replacing difficulty and reduced the replacing time.
Existing hydraulic oil cylinder driving formula distributor, for the ease of changing oil cylinder, generally need separately add the erecting stage of an oil cylinder on the top cover of distributor shell 5, the maintenance of the lower clack box of impact.Simultaneously rotating bearing 3 lubricated very difficult under domestic common hydraulic oil cylinder driving distributor, the inner link 15 of the lifting drive 1 of this distributor has central through hole, can be easily external lubrication oil be transported to lower rotating bearing 3 after by this hole, is lubricated.In addition, because the inside of this distributor has adopted inner enclosed cooling stave 12 and bottom enclosed aqueous cold plate 9, can avoid the corrosion to distributor inner components of distributor water coolant steam that other distributors occur, can also, easily by regulating cooling water pressure to regulate cooling water flow, not have water coolant to overflow into the interior trouble of stove yet.
The above, be only preferred embodiment of the present invention, is not intended to limit protection scope of the present invention.
