Defective at above-mentioned technology existence, provide a kind of in light weight and can be in patent application (97107046.6) prospectus at the inner oscillating chute type blast furnace charging in bell-less top device of realizing comprehensive cloth of furnace throat, this device principal feature is that the reel cage mechanism of device is on the same horizontal plane by two, the X-axis reel cage of crossbearer on the furnace throat section, the Y-axis reel cage constitutes, each reel cage respectively has an end to link to each other with the driving mechanism of this distribution device that is arranged on the furnace throat outside respectively, and driving mechanism can be by driving X-axis, the swing of Y-axis reel cage, and synthetic make distributor chute around the rotating circumferential motion of furnace roof medullary ray, when two reel cage wobble amplitude are zero simultaneously, be suspended on distributor chute on the reel cage just on the position of center line of furnace roof, so just can finish the center cloth of furnace roof, thereby realize omnibearing cloth.But this device also has certain deficiency, promptly in order to realize that two reel cages are at grade respectively along two vertical direction swings, must be equipped with two reel cages and driving mechanism respectively, and two reel cages are again mutually perpendicular on the horizontal plane, so just make and this device relatively large, structure relative complex that takes up room implement comparatively trouble.
The objective of the invention is to provide a kind of and when realizing comprehensive cloth, have the more oscillating chute type blast furnace charging in bell-less top device of simple structure at the defective that above-mentioned prior art exists.
For achieving the above object, oscillating chute type blast furnace charging in bell-less top device of the present invention is made of chute hitch, reel cage mechanism and driving mechanism, its mid cradle mechanism comprises that one is in and traversed the reel cage that the blast furnace central axis is installed, can be swung on the horizontal plane, described reel cage is passing blast furnace place employing sealing means, its center position at blast furnace is hanging the chute hitch that has a doline distributor chute, and distributor chute links to each other with a push-pull rod in its underpart; In described driving mechanism, have its axial line and reel cage axial line perpendicular by the external transmission decelerating device driven rotary and the transmission shaft that can move along its axis, and transmission shaft links to each other with an X-over by a pivoted link, and have an end of a swing arm to be installed among the X-over, and swing arm can rotate in X-over, but can not take place along its axial moving; Described swing arm is the orthogonal crank axle of cruciform by one with reel cage in the middle and is installed on the reel cage, and the cruciform orthogonal points is the axial line of transmission shaft and the crossing intersection point of axial line of reel cage just; The other end of described swing arm links to each other with the other end of push-pull rod; And the intersection point of the orthogonal intersection point of cruciform, blast furnace central axis and reel cage central axis, push-pull rod central axis are formed a parallelogram with the intersection point of sway bar center axis and distributor chute central axis is common respectively, its characteristics are: the other end of described transmission shaft passes blast furnace, and adopts sealing means at the place of passing through.
Above-mentioned oscillating chute type blast furnace charging in bell-less top device drives the swing arm revolution by its driving mechanism, because swing arm links to each other with reel cage, therefore can drive the reel cage swing, and then drives the distributor chute swing; Because swing arm links to each other with push-pull rod, by the push-and-pull of push-pull rod, and then the swing of drive distributor chute, finally realize the cloth of distributor chute again.In this device, because pivoted link and the phenomenon that swing arm pushes up mutually can not appear in pivoted link and X-over etc. in device, " dead point " position so just can not appear; Again because the reel cage that is adopted in this device has only one, and the power of the push-and-pull of the swing of reel cage and push-pull rod all is to derive from swing arm, and swing arm is installed on the reel cage, thereby makes that the structure of this device is extremely simple, implements more convenient than existing technology; In addition, because driving mechanism is arranged in the stove, only there are transmission shaft and reel cage to stretch out outside the stove.And reel cage is only around the swing of its axial line, so they are difficult for the slit takes place with blast furnace sealing contact position, so just is difficult for the leakage phenomenon of the interior coal gas of producer.
Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail.
Fig. 1 is the structural representation of the embodiment of oscillating chute type blast furnace charging in bell-less top device of the present invention.
Fig. 2 is the partial enlarged drawing in the device shown in Figure 1.
As shown in Figure 1 and Figure 2, in oscillating chute type blast furnace charging in bell-less top device of the present invention, comprise chute hitch 1, reel cage mechanism 2 and driving mechanism 3, its mid cradle mechanism 2 comprises that one is in the reel cage of swinging 21 that traversed the blast furnace central axis on the horizontal plane and installed, in order to prevent the gas leak in the blast furnace, reel cage 21 is passing blast furnace place employing sealing means (omitting among the figure), and reel cage 21 is a chute hanger bracket 22 in blast furnace central authorities; Chute hitch 1 comprises a funnel shaped distributor chute 11, distributor chute 11 is hung on the chute hanger bracket 22 in reel cage 21 stage casings with the vertical suspension gudgeon 12 of reel cage 21 axial lines by one at an upper portion thereof, and in its underpart by one with hang two forks that push-and-pull gudgeon 13 and that gudgeon 12 is parallel to each other is shaped as bifid push-pull rod 15 and link to each other, and the fork handle end of push-pull rod 15 links to each other with swing arm 31 pommels in the driving mechanism 3, and swing arm 31 is the orthogonal crank axle 33 of cruciform by one with reel cage 21 in the middle and is installed on the reel cage 21.And the intersection point of the orthogonal intersection point of cruciform (being the O ' point among Fig. 1), blast furnace central axis and reel cage 21 central shafts (being the O point among Fig. 1), push-pull rod 15 and the intersection point (being the N point among Fig. 1) of swing arm 31 both symmetrical center line and the symmetry centre axis of push-pull rod 15 and the intersection point (being M point among Fig. 1) of distributor chute 11 central axis are formed a parallelogram jointly; For distributor chute 11 is is freely mounted and dismounted, distributor chute 11 can be installed in earlier on the chute backing ring 14, link to each other with push-and-pull gudgeon 13 with suspension gudgeon 12 by chute backing ring 14 again.
In the driving mechanism 3 of this device, it passes blast furnace by external transmission decelerating device (omitting among Fig. 1) driven rotary and the transmission shaft 35 that can move along its axis one, and with the body of heater contact position be seal form (omitting among the figure); The axial line of the axial line of described transmission shaft 35 and reel cage 21 is perpendicular, and link to each other with an X-over 37 by a pivoted link 36, and the other end of swing arm 31 is installed in the X-over 37, and can rotate in X-over 37, but axial moving can not take place; Described crank axle 33 is the crossing intersection point of the axial line of the axial line of transmission shaft 35 and reel cage 21 just with reel cage 21 cruciform quadrature places (being the O ' among Fig. 1).In addition, not shaking in order to ensure transmission shaft 35 rotation, is symmetric line with the axial line of transmission shaft 35, be provided with one with the similar auxiliary connecting rod that can play poising action 38 of pivoted link 36, and make two connecting rods and transmission shaft 35 compositions one beveled structure.
The cloth process of oscillating chute type blast furnace charging in bell-less top device of the present invention is described below: can be divided into active force transmission speed reducer structure and auxiliarypower retarding mechanism in the external transmission decelerating device according to embodiment.Under the driving of auxiliarypower retarding mechanism, transmission shaft 35 moves along its axis, change at its angle (the ∠ KJO ' among Fig. 2) that drives between turning down connecting rod 36 and 31 liang of bar axial lines of swing arm, the angle between swing arm 31 and reel cage 21 axial lines is changed.Because 4 of MNO ' O among Fig. 1 are a parallelogram, under the drive of swing arm 31, what push-pull rod 15 will take place to parallel with reel cage 21 moves, will make that like this distributor chute 11 fascinates, the angle of its inclination (the ∠ NMO among Fig. 1) and swing arm 31 equate with inclination angle between reel cage 21 axial lines.When the medullary ray and the swing arm 31 of transmission shaft 35 and pivoted link 36 is in (being on the KO ' among Fig. 1, Fig. 2) on the same straight line, distributor chute 11 is just on the medullary ray of blast furnace, because the characteristic of X-over 37 and beveled structure, transmission shaft 35 rotations will produce centrifugal force, thereby make pivoted link 36 can depart from KO ' straight line, " dead point " position of cloth so just do not occur, promptly can realize the requirement of center cloth.
When the timing of the inclination angle of distributor chute 11, under the driving of active force retarding mechanism, transmission shaft 35 is rotated, and drives axial line (KO ' among Fig. 1 or Fig. 2) revolution that pivoted link 36, X-over 37 and swing arm 31 center on transmission shaft 35 together successively.Again because swing arm 31 links to each other with reel cage 21, so reel cage 21 will swing, and swing from both direction drive distributor chute 11 respectively by backing ring hanger bracket 22 and push-pull rod 15.The synthetic distributor chute 11 that will make of the swing of both direction is realized the rotation cloth around its central axis.As can be seen from Figure 1 the reel cage 21 that is adopted in this device has only one, and the power of the swing of reel cage 21 and push-pull rod 15 push-and-pulls all is to derive from swing arm 31, but swing arm 31 is not installed in the inside of reel cage 21, so just need not to increase the radial dimension of reel cage 21, thereby make that the structure of this device is extremely simple, weight is also lighter, implements more convenient than existing technology; In addition, because driving mechanism 3 is arranged in the stove, only there are transmission shaft 35 and reel cage 21 to stretch out outside the stove, and transmission shaft 35 utilizes the characteristic of beveled structure, make it along axial translation and rotation, 21 of reel cages are around its axial line swing, so they are difficult for the slit takes place with blast furnace sealing contact position, so just are difficult for the interior coal gas of producer and get leakage phenomenon.Oscillating chute type blast furnace charging in bell-less top device of the present invention, except applicable to the blast furnace, other shaft furnace top distributing gear also can adopt.
