Abstract
The utility model relates to a furnace top distributor with a hollow ring. A hollow ring structure capable of swinging in two ways is adopted; the hollow ring can swing; meanwhile, a chute barrel which is supported and connected inside the hollow ring also can independently swing. Thus, rotation of the chute barrel at any height can be achieved by a two-way swinging action; the function of swinging in any direction also can be achieved. A plurality of sets of meshing mechanisms meshed with conical gears and racks are integrated in an annular hollow cavity of the hollow ring, so that a complicated gear structure required by the traditional distributor is forcibly simplified; the cost is saved; the space utilization rate is improved.
Description
Technical field
The utility model relates to and a kind ofly belongs to metallurgical machinery equipment by the device of bidirectional swinging to roof material distributing, is applicable to the cloth of the furnace roof of various volume shaft furnaces or blast furnace.
Background technology
Blast-furnace top distributing device commonly used mainly is to adopt the Planetary Gear Transmission wheel casing to carry out mechanically decoupled at present, the action of will turning round, fascinate is delivered to respectively traversing mechanism and tilting mechanism, as everyone knows, adopt the planetary gear transmission mechanism more complicated, so price is also relatively more expensive; Also there is recently distributor to begin to adopt the mode of electric decoupling zero, by motor or the transmission of hydraulic way mate gear, namely cancels the planet differential case, with two motor independent drive swiveling gears and the gear that fascinates, the structure of whole cloth wheel casing is simplified; But owing to only having cancelled the sun and planet gear draw box mechanism, rock problem for the rotating cylinder bottom, and the problem of the stability of whole rotating part does not solve still.Simultaneously, owing to there is the revolution action in this mechanism, the cooling of distributor and nitrogen envelope are all brought a difficult problem, cause water loss greatly and the large problem of nitrogen consumption.
The scheme that some swings also occurred recently, but also existence and stability is relatively poor, the inaccurate problem in cloth position.
The utility model content
The technical problems to be solved in the utility model is the defects that overcomes prior art, and a kind of furnace top distributing gear with cavity ring is provided, and simplifies energetically the physical construction of distributor, and structure is small and exquisite, simple and reliable and stable; By the simple control combination of double-swing, can realize rotation or swing cloth multi-direction, various ways simultaneously.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
With the furnace top distributing gear of cavity ring, comprise that mainly cavity ring driving mechanism, cavity ring, chute driving mechanism, chute drive cone gear, annular rack, chute cone gear, chute and shell; It is characterized in that:
Cylinder-like shell vertically is fixed on shaft furnace or the blast furnace roof; The cavity ring of ring body cavity-like is horizontally disposed with in the enclosure; Along cavity ring X circle core shaft direction, one of cavity ring bring out axle by bearings on shell, the other end shaft is by dock with cavity ring driving mechanism shaft after the shell bearings, the cavity ring driving mechanism is fixed on outside the shell;
On the perpendicular Y circle core shaft of X circle core shaft direction, be connected to two chute back shafts on the chute outer wall by the bearings on the cavity ring inner side-wall after, stretch in the ring body cavity; Wherein a chute support the tip of the axis is connected with the chute cone gear in the ring body cavity;
The chute driving mechanism places the shell outside and is fixed on cavity ring one and brings out on the axle, and chute driving mechanism shaft inwardly stretches into the ring body cavity and connects chute along X circle core shaft direction and drives cone gear; Be fixedly installed with one heart the annular rack of slightly being longer than quadrant length between the inside and outside sidewall of cavity ring ring body cavity; In the ring body cavity, chute drives cone gear in X circle core shaft place and the engagement of annular rack one end, and the annular rack the other end is in Y circle core shaft place and the chute cone gear engagement that is fixed on the chute back shaft.
As a kind of form of distortion of technique scheme, along X circle core shaft direction, the two ends shaft of cavity ring docks a cavity ring driving mechanism shaft after by the shell bearings separately.Can realize thus swinging more stably and rotating cloth.
As the further improvement separately of above-mentioned two kinds of technical schemes, along X circle core shaft direction, be placed in shell two outsides and being separately fixed on the shaft of cavity ring two ends of two chute driving mechanisms, each chute driving mechanism shaft all inwardly stretches into the ring body cavity and connects separately a chute and drives cone gear; Along Y circle core shaft direction, the end that two chute back shafts stretch in the ring body cavity arranges a chute cone gear separately; Being fixedly installed with one heart two sections between the inside and outside sidewall of cavity ring ring body cavity is the angular distribution annular rack of slightly being longer than quadrant length, each annular rack one end meshes with a chute cone gear respectively, and the other end drives the cone gear engagement with a chute respectively.
As further improvement in the technical proposal, described cavity ring driving mechanism and chute driving mechanism are one or more in gear motor, hydraulic push rod, air-leg, the electric pushrod; Employing is during with the driving mechanism of push rod, and the push rod end is connected on the distributor by power conversion mechanism respectively.
The principle of work of above-mentioned distributor: by control cavity ring driving mechanism, cavity ring and chute swing around X circle core shaft direction with same frequency and amplitude simultaneously, and pendulum angle can be regulated arbitrarily in the design angle scope;
By control chute driving mechanism, chute is swung around Y circle core shaft direction separately, pendulum angle can be regulated arbitrarily in the design angle scope, and this moment, cavity ring was motionless;
By controlling simultaneously cavity ring driving mechanism and chute driving mechanism, cavity ring and chute are all swung with same frequency and amplitude simple harmonic quantity, and 90 ° of the phase phasic differences of two simple harmonic quantity swings, make chute around with X circle core shaft and Y circle core shaft all vertical Z direction finish and rotatablely move, speed of rotation is the frequency that simple harmonic quantity swings, the direction of rotation is leading or backward relevant with phase differential, and the height that chute is lifted is relevant with the amplitude that simple harmonic quantity swings;
By controlling simultaneously cavity ring driving mechanism and chute driving mechanism, cavity ring and chute are swung synchronously; At this moment, chute at an angle side oscillation outside the Z direction under the effect that swings synchronously; The amplitude of oscillation that chute swings is cavity ring and chute amplitude of fluctuation square root sum square, the concrete direction of chute side oscillation outside the Z direction and the Amplitude correlation that both swing.
Beneficial effect:
Having adopted can double-swing cavity ring structure, and cavity ring itself can swing; The chute of simultaneously cavity ring inner support connection also can swing separately, by both bidirectional swinging actions, can realize that chute rotates at arbitrary height, the function that also can swing to any direction, and cone gear and many covers engaging mechanism that tooth bar meshes all be integrated in the ring body cavity of cavity ring; Simplify energetically the needed complicated gear structure of traditional distributor, saved cost and improved space availability ratio.
Simultaneously, by in the cavity ring circumference, increasing annular rack, can increase the cloth stationarity.By rotating the way of realization of each driving mechanism, also can increase applicable situation.
In addition, the utility model can have multiple variation array configuration, selects according to construction cost, and is flexible.
