Description
Technical field
The present invention relates to a kind of blast furnace support equipment, particularly a kind of fork arm type equal blast furnace bellless distributor.
Background technology
Blast-furnace channel distributor is the key equipment that blast furnace adds charging, because it has the flexible and uniform feature of cloth, obtain applying very widely, and the flexible stable motion of chute be channel distributor can be flexibly and the key of uniform distribution, the position of general chute is controlled by its α angle with respect to distributor axis and β angle, α angle is the angle between chute and distributor axis, in order to reach the uniform object of cloth, in cloth process, chute need to carry out the motion of both direction, a kind of motion is the swing that changes the angle between itself and distributor casing axis, object is to change the α angle of chute, another is the circumferential motion that drives chute to produce around distributor axis by means of drive unit, object is to change the β angle of chute, the α angle of chute is generally to do upper and lower straight reciprocating motion by guide wheel along guide rail by backing ring and lower rotating bearing to realize, because backing ring diameter is larger, in normal use procedure, the suffered power from chute of backing ring is partial load, stress point is the β angle synchronous rotary with chute around its axis, so, the control of backing ring hoisting appliance kinematic accuracy is the key factor that directly affects chute α angular accuracy, also be to affect the distributor key factor in work-ing life, the backing ring lifting mechanism adopting at present mainly contains following several:
1) rope hoisting type
Its primary structure is to promote backing ring by steel cable, only with unidirectional reinforcing, and the descending dependence self gravitation of backing ring, reliability is low; Backing ring location relies on the many groups roller set on its outer ring to realize with the guide rail being arranged on distributor cabinet wall, because every group of roller set comprises the vertically disposed roller of at least two covers, adjust complicated, also be difficult for ensureing that the geometric centre of lower swing bearing overlaps with rotation center, when operation, backing ring rocks obviously, backing ring is shorter work-ing life, and reliability is low, directly affects blast furnace production stability.
2) single armed double link control type
This mechanism is by the lifting of single armed double link control backing ring, can realize two-way reinforcing, but transmission chain is longer, when operation, towing loop has lateral component to produce, and backing ring location is same relies on the many groups roller set on its outer ring to realize with the guide rail being arranged on distributor cabinet wall; Form because every group of roller set remains by two groups of rollers that vertically arrange, adjust difficulty, and the lateral component in when operation makes backing ring geometric centre be difficult for overlapping with the rotation center of lower rotating bearing, generation bias, backing ring rocks obviously.
3) both arms four connecting rod control types
This mechanism adopts two groups of holohedry four link type α angle driving mechanisms, there is mechanical interlock, synchronous driving, the suffered radial component of towing loop such as can offset completely at a series of outstanding advantages, overcome the radial component that one group of double-connecting rod type α angle driving mechanism brings to lower rotating bearing and backing ring thereof, the location of lower rotating bearing and backing ring thereof is made up of jointly four connecting rods and one group of guide wheel and guide rail, guide wheel is few, adjust easily, but because the transmission chain that α angle drives is oversize, progressive error is wayward, while causing distributor operation, backing ring rocks still obvious, reliability decrease.
4) three hydro-cylinder interlock control types
The problem of this mechanism's maximum be three hydro-cylinders be synchronously not easy realize, complex structure, trouble spot is more, once asynchronous interlock appears in three hydro-cylinders, to the infringement of distributor unrepairable often.
5) Luxembourg PW type
The α angle driving mechanism of Luxembourg PW type furnace top distributing gear is made up of a pair of open gear pair and a pair of turbine and worm pair, compact construction, stable performance, but very high to the requirement of material and complete processing thereof, the expense of spare part and maintenance is also extremely high, belong to the high device type of better performances price, cost performance is not high, is difficult for promoting.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of transmission chain is short, simple in structure, low cost of manufacture and the backing ring lifting mechanism without lateral component, improves the fork arm type equal blast furnace bellless distributor of its work-ing life and stability.
