    Lubrication for a rotary shaft positioned within the upper region of a blast furnace is accomplished by mounting a mechanically actuated pump for rotation with a reduction gear box through which the rotatable shaft is driven. The pump is periodically operated by means of an adjustable cam plate mounted on a sector gear which is affixed to the rotatable shaft; torque being transmitted to the shaft via the sector gear which is driven by a pinion coupled to the reduction gearing.

    专利说明:

    However, the supply of lubricating mediums with these seals and support sleeves is difficult, since the latter, together with the rotary housing or, respectively, their currently used reduction gearboxes, make turning movements around the longitudinal axis of the intake passage.
    The lack of a lubrication system is associated with a tightness problem. Due to the high temperatures prevailing in the upper part of the blast furnace, the oil or, accordingly, the lubricant becomes very fluid, which makes it very difficult to provide a seal.
    The aim of the invention is to increase the reliability of the lubricant.
    For this, the proposed lubrication system is equipped with an additional spring-loaded oil nasis, which is actuated by the front side of the Toothed segment, with a precisely fixed strap attached to the segment, and a lever-cam assembly is made between it and the pump plunger.
    FIG. 1 shows a schematic general view of the installation and suspension mechanisms of the distribution loading tube in section; in fig. 2 reduction gearbox with a slit of the suspension parts of the discharge pipe requiring lubrication; in fig. 3 lubricating device.
    Distribution loading tube 1 includes its own installation and suspension mechanisms 2 (Fig. 1)
    The setting mechanism mainly contains two gear drives 3 and 4. for actuating the rotary body 5 and for realizing the rotational movement of the distribution pipe of the loading pipe 1 around the central inlet channel 6 and the longitudinal axis of the shaft furnace and for inclined movement of the loading pipe 1 relative to the longitudinal axis the furnace using two rotating together with a rotary body 5 around the inlet channel 6 reduction gearboxes (not shown). Gear drives 3 and 4 are powered by a BcUOTCH from the first and, respectively, the second production engines (shown on JK drawings).
    Distribution loading tube 1 in its upper part has two protruding arms 7 in the form of a duck nose, with which it rests on two trunnions 8 and is rigidly fixed to them using known means. Both axles 8 of the shaft pass through the wall of the rotary body 5, with which it, when gripped by the loading tube 1, rotates around the inlet of the other channel b. On each of the two axles of the shaft, a gear segment 9 is mounted securely in relation to the rotation, which can be driven through reduction gearboxes for the purpose of inclined movement of the loading tube 1. In FIG. 1, the distribution loading tube 1 is depicted in two different inclination positions, represented continuously by the I-dashed lines.
    Symmetrically with respect to the intake channel 6, there are two reduction gearboxes 10 in which gear sets are placed. The gear 11, through the gearbox 10, drives the gear 13, which is in engagement with the gear segment 12, while the gear segment 1.2, on its part, is mounted firmly against turning the shaft 8 on the axle 8 and, as a result, it rotates around the gear 13 its longitudinal axis O. The fastening of the shoulder 7 on the shaft axle 8 is realized by means of the bot 14. passing through the aperture. Thus, when the gear 11 is caused by the gear drive 4 by means of the gear 13 and the segment 9 A slant movement of the distribution loading tube 1 is achieved.
    Having the ability to rotate around its longitudinal axis, the shaft axle 8 is located in support sleeves 1 and sealed with seals 16 and 17. Supporting sleeves 15, for example, Simmer rings, cannot be used because of unfavorable conditions to ensure the smooth functioning of this support. conditions to ensure the sealing must be provided heat-resistant gaskets.
    According to the invention, each of the two reduction gearboxes 10. is attached together with the latter around the inlet channel 6 of the oil pump 18, which has the ability to supply lubricant under pressure between the bearing bushings 15 and the axle shaft 8. This oil pump 18 is controlled by the rotational movement of the toothed segment 9 around its axis 0. The pump 18 is designed as a simple pressure pump with a cylinder 19 and a plunger 20 moving in it, with which the lubricant in the cylinder 19 is fed through pressure in the location of the support sleeves 15. The plunger 20 of the pump is under the action of a return spring 22 made as a compression spring, which is located on the plunger 20. The outermost point of the plunger 20 functions as a controllable swinging lever 23 of the pusher 24.
    The oil pump 18 for a long time receives lubricant 25 from the gearbox 10 rotating around the inlet channel of the vessel 26 with a lubricant reserve. The latter through a return valve 27 is connected to the cylinder 19 of the pump 18. Inside the vessel 26 with a reserve of lubricant, a piston 29 interacting with the pressure spring 28 is provided, which supplies the lubricant 25 from the vessel 26 through the return valve 27 under pressure to the cylinder 19.
    The lubricant reservoir 26 can be filled either periodically, for example, during the scheduled stopping of the furnace, or it can be a replaceable cartridge.
    The swing arm 23 rotates around the support 30 and is loaded through the plunger 24 by the spring 22 to rotate counterclockwise. The swing arm has a freely rotating roller 31, which provides parallel pressure force of the swing arm 23 to the plunger 20 of the pump of its longitudinal axis. The swing arm 23 has another freely rotating roller 32 for engaging with an arcuate bar 33 fixed on the outer end side of the toothed segment 9. To facilitate the interaction between the bar 33 and the roller 32, the bar that serves to control the swing arm 23 relative to the pressure of the spring 22 is on its own the outer face on one side is filled with a bevel 34.
    Plank 33 is screwed, preferably with a toothed segment 9 and, to accomplish this, has two holes 35. The latter are preferably made as bent elongated holes so that the position at an angle from the center of the bar 33 on segment 9 changes simply and that when you turn the latter, start lifting the roller 32 could be adjusted in any case by, means, your bevel 34.
    To prevent the swinging arm 23 from tilting under the action of the spring 21 back above a certain position, for example, above the one shown in FIG. 3, a stop may be provided (not shown in the drawings).
    The solid line position of segment 9 in FIG. 1 and 3 correspond to the elevated position of the discharge pipe 1, i.e. the one position in which it directs the feed material towards the periphery of the furnace. If the loading tube 1 should be more inclined to the furnace axis, then the gear 36 is controlled so that the segment 9 rotates around its longitudinal axis O in the counterclockwise direction. During the lowering of the loading tube, segment 9 gradually passes
    to the position depicted by the dashed line in FIG. 3
    The swivel arm 23 and bar 33 are located relative to each other in such a way that the latter is based on the one shown in FIG. 3 by a dashed line positioning the angle from the center (which, for example, may correspond to the angle of inclination relative to the longitudinal axis of the furnace), yft was driven by the oil pump 18 by the action of the tilting lever 23 against the action of the spring 22. The oblique movement of the distribution loading pipe 1 is over tilt down
    The 5th position serves to control the oil pump and to supply lubricant to the journal 8 of the shaft. If the loading tube 1 is lifted again from the vertical position, then the hex 36 is controlled so that
    0 would segment 9 rotate clockwise. In this rotational movement, the roller 32 frees from the action of the bar 33, due to what the plunger 20 of the pump moves back
    5 and the cylinder 19 is again provided with lubrication by the action of the spring 28 on the piston 29 of the vessel 26 with a lubricant reserve.
    At the same time, the scheme for beskolpakovoy
    0 batch loading carried out in spiral-shaped or concentric circles includes an inclined movement of the distribution loading tube between 8 and 50 relative to the longitudinal axis of the furnace. The slopes below are set only as an exception if the feed material should fall down perpendicular to the surface of the melt. The loading tube is periodically lowered all the way down.
    0 up to the vertical and due to the interaction of the toothed segment 9 and the oil pump 18 ensure adequate fit of the journal 8 of the shaft. This kind of lubrication can also be carried out simultaneously with the central loading of the surface of the melt.
    The repetition of lubrication operations, as well as the quantitative power of the oil pump, must be matched in such a way that both 8 breast pins receive a sufficient amount of lubricant. The local location of the oil pump and / or the location of the.
    The angle 5 from the center of the bar 33 on the segment 9 can be varied in such a way that the angle of inclination of the loading tube, during which the lubrication process takes place when the loading tube approaches the longitudinal axis of the domain furnace, can be selected by anyone. Equally, the oil pump can be positioned so that it can be controlled by another extreme point of the toothed segment 9, while the lubrication process is carried out when the loading tube is above a certain angle, for example 50
    The required amount of lubricant is small, as the speed. The rotation and the angle of rotation of the axles of the shaft are small.
