Embodiment
Below in conjunction with accompanying drawing and embodiments of the invention distributor of the present invention is done further detailed explanation.
Fig. 1 is the enclosed water-cooled blast-furnace top distributing device structural representation that the present invention is based on the quick change oil cylinder, and as shown in Figure 1, the essentially consist of this distributor comprises: up-down driven unit 1 (amounting to three, uniform distribution); Last rotating bearing 2; Turning down supporting 3; Slip box circle 4; Distributor shell 5; Rotor 6; Connecting rod 7; Chute 8; Bottom enclosed aqueous cold plate 9; Suspension assembly 10; Center trunnion 11; Inner enclosed water wall 12; Rotary drive assembly 13.
Please with reference to Fig. 1, the rotary drive assembly of this distributor 1 with reducing motor as drive member.Distributor shell 5 is installed on the blast furnace lip ring, its medullary ray and blast furnace central lines.Rotary drive assembly 13 complete installations are on the top cover of distributor shell 5; The master wheel engagement of pinion(gear) and last rotating bearing 2 is installed on the output shaft of rotary drive assembly 13; The top cover of last rotating bearing 2 inner rings and distributor shell 5 is fixed, and the outer ring links to each other with rotor 6; Up-down driven unit 1 totally three be uniformly distributed with on the top cover that is fixed on distributor shell 5; Up-down driven unit 1 supports 3 outer rings through threaded rod and turning down and links to each other; The inner ring of turning down supporting 3 is connected with slip box circle 4; Slip box circle 4 links to each other with suspension assembly 10 through connecting rod 7, and suspension assembly is installed on the chock of rotor 6.Suspension assembly is used for fixing chute 8.Bottom enclosed aqueous cold plate 9 is installed on the base plate of distributor shell 5.On the top cover of inner enclosed water wall 12 lifting distributor shells 5.
Its principle of work is following: up-down driven unit 1 drives slip box circle 4 and pumps along rotor 6 axis directions, and this connecting rod crank mechanism that moves through two the swing arms compositions of connecting rod 7 in suspension assembly 10 realizes that suspension assembly 10 drives chutes 8 and fascinates; Rotary drive assembly 13 makes rotor 6 rotations through geartransmission; And rotor 6 top chocks also drive suspension assembly 10 and chute 8 rotations; Through the combination of the different rotations and the mode of fascinating, can realize various distributing modes such as annular, fan-shaped and spiral neatly.
Fig. 2 is up-down driven unit structural representation shown in Figure 1, and is as shown in Figure 2, and this up-down driven unit mainly is 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 1 ends are the hinged head that hangs, and the other end is a screw thread, and the hole is opened in inside.Hoist cylinder 16 is opened two rod standard oil cylinders in hole for piston rod.Fix through set nut behind the hole on the inner link 15 process hoist cylinder piston rods, inner link 15 is hinged through articulated linkage 17 and threaded rod 18, and whole up-down driven unit links to each other through the outer ring of threaded rod 18 and turning down supporting.
This distributor is compared with domestic and international the most frequently used distributors such as planet differential distributor, have simple in structure, operate steadily, be convenient to safeguard and characteristics such as with low cost.Hydraulic oil cylinder driving distributor with respect to domestic appearance; This distributor adopts the oil cylinder up-down Drive Structure with quick change function; Only need unclamp the bolt that installs and fixes of set nut 14 and oil cylinder itself on the up-down driven unit 1; Can realize the quick replacing of hoist cylinder 16, compare, dwindle the replacing difficulty greatly and reduced the replacing time with existing hydraulic oil cylinder driving formula distributor.
Existing hydraulic oil cylinder driving formula distributor generally needs on the top cover of distributor shell 5, to add in addition the erecting stage of an oil cylinder for the ease of changing oil cylinder, and influence is the maintenance of clack box down.The lubricated very difficulty of simultaneously domestic common hydraulic oil cylinder driving distributor turning down supporting 3, 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 turning down supporting 3 after through this hole, is lubricated.In addition; Because inner enclosed cooling stave 12 and bottom enclosed aqueous cold plate 9 have been adopted in the inside of this distributor; Can avoid the corrosion of distributor water coolant steam that other distributors occur to the distributor inner components; Can also regulate cooling water flow through regulating cooling water pressure easily, also not have water coolant to overflow into the interior trouble of stove.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.
