Description

The KR blanking jacking system of adjustable gaps

Technical field

The utility model relates to steelmaking equipment, specifically belongs to the blanking jacking system of KR desulfurization.

Background technology

In the steel-making KR desulfurization treatment process, for improving the desulfurization quality, reach the purpose of low-sulfur iron, must have good lifting alerting ability in the calcium carbide charging system, but in process of production, it is that sulphur in the molten iron and objectionable impurities are handled that the KR sweetener mainly acts on, promptly, add calcium carbide by the lifting blanking groove and carry out the molten iron stirring through after before skimming, sulphur in the molten iron and objectionable impurities is floating to the surface, skim after carrying out again, remove sulphur and objectionable impurities in the molten iron.Normally lifting can't add calcium carbide but owing to blanking lifting skewed slot in the production process is stuck easily.Therefore, the normal lifting of blanking lifting skewed slot becomes the important step that guarantees production blanking direct motion.

At present, some scientific and technical personnel are carrying out the research of blanking lifting skewed slot device always both at home and abroad, but just at present, major measure is to take four copper sheathing guiding, but it can't guarantee lubricant effect under high temperature, high dirt, and, cause directly rubbing and produce frequent stuck phenomenon again because copper sheathing and pilot bar are straight-line motions.Therefore, become a suitable stubborn problem of current smelting system.

The utility model content

The purpose of this utility model is to overcome the deficiency of present existence, the straight-line motion in a kind of KR sulfur removal technology and the blanking lifting skewed slot that directly rubs are provided, change rotatablely moving and rotating the thinking that connects of mill of scalable guiding clearance into, make the KR blanking jacking system of more safe and practical, the workable and economic adjustable gaps of this kind scalable blanking lifting skewed slot device in the production process.

Realize the technical measures of above-mentioned purpose:

The KR blanking jacking system of adjustable gaps comprises pilot bar, and it is: pilot bar is located in the U-shaped elevator chamber; On the inwall of the both sides of U-shaped elevator chamber adjusting knurl and tight pulley are installed all, the top of pilot bar is conditioned the wheel chucking, and the bottom of pilot bar is fixed and takes turns chucking; Adjusting knurl is connected with the U-shaped elevator chamber by eccentric shaft, and tight pulley is connected with the U-shaped elevator chamber by anchor shaft; One end of regulating plate is housed on eccentric shaft, and the other end of regulating plate is contained in the chute of U-shaped elevator chamber inwall, and regulating plate is a polygon with the hole that eccentric shaft is installed mutually; Be provided with end cap one in the outside of adjusting knurl, end cap two be housed in the outside of tight pulley.

It is characterized in that: eccentric shaft is made up of bearing fixing section one, bearing fixing section two, the eccentric position of adjusting knurl section, regulating plate position section, push bolt position section.

It is characterized in that: the degree of eccentricity of the eccentric position of adjusting knurl section is at 0～3 millimeter.

It is characterized in that: the wheel rim of adjusting knurl and tight pulley is a U-shaped, and pilot bar is stuck in the U-shaped of wheel rim.

It is characterized in that: the regulating plate position section on the eccentric shaft is a polygon, and its shape matches with the polygonal hole of regulating plate.

The utility model makes in the production process this kind scalable blanking lifting skewed slot device more safe and practical, workable and economical, has reduced industrial accident incidence and cost, has improved economic benefit.

The specific embodiment

Be described further below in conjunction with accompanying drawing:

The KR blanking jacking system of adjustable gaps comprises pilot bar 1.Pilot bar 1 is established only in U-shaped elevator chamber 2; 8 four of the eccentric shafts that whole processing is made up of bearing fixing position section 1, bearing fixing position section 24, the eccentric position of adjusting knurl section 5, regulating plate position section 6, push bolt position section 7, and regulating plate position section 6 is processed into triangle or quadrangle or pentagon or hexagon, the degree of eccentricity of the eccentric position of adjusting knurl section is 0 millimeter/1 millimeter/2 millimeters/2.5 millimeters/3 millimeters; On the inwall of the both sides of U-shaped elevator chamber 2, be as the criterion with pilot bar 1, each side wall upper part is installed two eccentric shafts 8, its trend is determined according to the trend of pilot bar 1, with adjusting knurl 9, regulating plate 10 triangles or quadrangle or pentagon or hexagon nose end are contained in eccentric shaft 8 corresponding positions, the other end of regulating plate 10 is contained in the chute 11 of U-shaped elevator chamber 2 inwalls, pilot bar 1 is clamped on radius with pilot bar 1 in the wheel rim U-lag 12 of the adjusting knurl 9 that cooperates, eccentric shaft 8 links together by bolt and U-shaped elevator chamber 2, in the shaft end side machined grooves 1 of adjusting knurl 9, flush fit embeds end cap 1 with eccentric shaft 8 end caps firmly in groove 1; On the inwall of the both sides of U-shaped elevator chamber 2, be as the criterion with pilot bar 1, each lower sidewall is installed two anchor shafts 15, suit tight pulley 16 on anchor shaft 15, the bottom of pilot bar 1 be fixed the wheel 16 tightly the card, anchor shaft 15 links together by bolt and U-shaped elevator chamber 2, in the shaft end side machined grooves 2 17 of tight pulley 16, flush fit embeds end cap 2 18 with anchor shaft 15 end caps firmly in groove 2 17.

Operating principle of the present utility model:

Bolt on the earlier loosening chute 11, after regulating plate 10 rotates a certain angle, it drives eccentric shaft 8 and rotates, thereby make eccentric shaft 8 drive adjusting knurl 9 and change eccentric angle, thereby adjusting knurl 9 changes with the gap of pilot bar 1, after reaching required running clearance, lock the bolt on the chute 11 again, make rotatablely moving and rotate friction and reducing greatly of this device.

The above technology contents that discloses only is preferred embodiment of the present utility model, can not limit the interest field of the utility model with this, and therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
