Description
The utility model relates to a kind of blast furnace top charging equipment, the particularly distribution device of blast furnace bell-less roof material distributing chute.
At present, the loading device of blast furnace mainly contains two big classes, be bell type and no bell type, no bell type distribution device is realized uniform distribution by chute, this distribution device cloth is flexible, favorable sealing property, it is applicable to the blast furnace of mesohigh operation, (patent No.: 85109284), its chute swing relies on three synchronous hydraulic cylinders to drive and realizes, and the rotation of chute relies on fluid motor-driven to realize as Chinese patent " device with hydrostatic transmission for feeding material ", its processing and manufacturing, safeguard that installation is superior than the distribution device of planet differential transmission rig, but, be easy to generate the asynchrony phenomenon of Driven by Hydraulic Cylinder, thereby make the backing ring that drives the chute swing move up and down not steady, running resistance is big, even the stifled phenomenon of card takes place, chute pivot angle control accuracy is low, so apparatus processing is made the precision prescribed height; And oil motor is in the medium speed wild effect that rotatablely moves, and causes the chute rotation inaccurate; And the problem that has an electric liquid to change, cause mechanism's complexity, increase facility investment.
The purpose of this utility model be for the blast furnace bell-less furnace roof provide a kind of reasonable in design, mechanism simple, operate steadily, the bf fabric device of chute pivot angle control accuracy height, rotation transmission ball-screw transmission accurately chute.
The purpose of this utility model reaches by the following technical programs.A kind of bf fabric device of ball-screw transmission chute, comprise: gudgeon, backing ring, annular jib, chute, crank, carriage, turnbarrel, transmission-case cover, transmission case body, water-cooled chassis, trunnion, water-cooled sheath, chute rotary drive motor, step-down gear, chute rotation transmission driver pinion, it is characterized in that: it also comprises swing bearing, chute pivot angle drive-motor, step-down gear, chute pivot angle transmission driver pinion, synchronous pinion gear, ball screw assembly,, tapered roller, V-type rail and the elastic roller of band bidentate circle.
Ball screw assembly, in the chute pivot angle transmission system has three and identical, all vertically arrange and stretch in the casing at the same circumference in transmission-case cover upper edge, synchronous pinion gear is equipped with at dress conical bearing, middle part in its upper end, the synchronous pinion gear that be equipped with at chute pivot angle transmission driver pinion and ball screw assembly, middle part all meshes with the upper ring gear of the swing bearing of being with the bidentate circle, and the nut of backing ring and ball screw assembly, is fixed.
Arrange all that in casing on the support of V-type rail and backing ring paired elastic roller being housed is complementary.
Clamp paired tapered roller on the annular jib between backing ring and the turnbarrel, tapered roller puts in the race groove of backing ring and is with it and contact alternately layout up and down.
The motor of chute pivot angle transmission is an AC servo motor, interior dress photoelectric encoder and stopper.
Between the water-cooled sheath and turnbarrel of center trunnion, and between turnbarrel and the water-cooled chassis, the same, the radially soft packing seal of radially axially high temperature resistant with four roads and the self lubricity of the twice that do not wait of installation dimension of sealed structure all is equipped with at this two place.
The beneficial effects of the utility model are:
(1) owing to replaced former " Hydraulic Station--proportional valve group--hydraulic efficiency systems such as hydro-cylinder " with " motor--step-down gear--ball-screw auxiliary driving ", thereby solved the asynchrony phenomenon of Driven by Hydraulic Cylinder, the backing ring that drives the chute swing is operated steadily, improved transmission accuracy, its chute pivot angle bearing accuracy being less than equaling 0.1 °, is that the distributor of other type is incomparable;
(2) the tapered roller arrangement form is arranged for contacting alternately up and down in pairs, has guaranteed that chute is in whole rotary oscillation traveling comfort;
(3) adopted V-type rail to cooperate guiding movement with elastic roller, eliminated gap between the two, running resistance is little;
(4) compare with hydrostatic transmission, reasonable in design, simple in structure, make convenient for installation and maintenancely, equipment is reliable, and the manufacturing accuracy of equipment is required to decrease;
(5) because the soft packing seal of radial and axial high temperature resistant, self lubricity is housed, can prevents effectively that stove dirt from entering in the airtight box, and can significantly reduce the hermetic seal gas consumption, even the air seal of can stopping using.
The utility model will be further described below in conjunction with accompanying drawing:
