Description
Technical field
The invention belongs to technical field of metallurgical equipment, disclose a kind of blast furnace bellless distributor equipment, be applicable to the application of big-and-middle-sized blast furnace.
Background technology
The blast furnace bellless distributor of present domestic use is except that adopting the PW form, present domestic employing exists the crank rotation that slippage is arranged in the horizontal direction by the chute type of drive that lifting platform is converted into the crank rotation, the instantaneous angular velocity of chute transmission shaft changes, cause the speed instability of fascinating, crank head steamboat slides in chute, steamboat and slideway serious wear.Only be applied to small blast furnace at present, this structure stress will be more unfavorable concerning large blast furnace, be difficult to guarantee normal use.
Summary of the invention
The objective of the invention is to draw various advanced experiences and technology for satisfying large blast furnace bellless distributor production domesticization needs, development and design goes out to be applicable to the bellless distributor equipment of large blast furnace.
Purpose of the present invention realizes in the following way: mainly be made up of rotating machine, top speed reduction unit, rotary pinion, center trunnion, top swivel bearing, rotator, bottom swivel bearing, lifting gantry, water-cooling system and lagging material, chute transmission shaft, liner, hoist cylinder, connecting rod, bearing support, toothed segment, tooth bar, pinch roller, housing, chute etc.Rotating machine is installed on the speed reduction unit of top, rotary pinion that the top reducer output shaft is installed and the engagement of the master wheel of top swivel bearing, the inner ring and the housing of top swivel bearing are fixed, the outer ring of top swivel bearing is connected with rotator, the chute transmission shaft is fixed on the rotator by bearing support, and chute is installed on the chute transmission shaft.Hoist cylinder is fixed on the housing, and hoist cylinder connects lifting gantry by connecting rod, and the outer ring of lifting gantry and bottom swivel bearing is fixed, and on the inner ring of bottom swivel bearing tooth bar is installed, tooth bar and the toothed segment engagement that is contained on the chute transmission shaft.
Principle of work: rotating machine is installed on the speed reduction unit of top, rotary pinion that the top reducer output shaft is installed and the engagement of the master wheel of top swivel bearing, the rotating machine rotation drives the outer ring and the rotator rotation of top swivel bearing, be installed in bearing support on the rotator, chute transmission shaft along with rotation, the rotation of drive chute, the function that rotatablely moves of realization chute.3 hoist cylinders are fixed on the housing, hoist cylinder connects lifting gantry by connecting rod, the outer ring of lifting gantry and bottom swivel bearing is fixed, the oil cylinder stretching motion drives lifting gantry and descends or rise, the inner ring upper rack that drive is installed in the bottom swivel bearing descends or rises, drive the toothed segment rotation on the chute transmission shaft, fascinate, realize the motor function of fascinating of chute thereby drive chute.
The present invention adopts the rack pinion transmission to solve the problems referred to above well, makes the linearizing of chute turning angle, and the velocity-stabilization that fascinates is easy to the detection control of angle.Also solved simultaneously the problem of this position serious wear.Simultaneously, be general gear reduction unit with the designs simplification of top step-down gear, the angle changes because the chute that chute rotation transmission brings fascinates not need to come balance by planetary gear speed reducing mechanism.Chute rotates and fascinates independent fully.The bottom step-down gear (gear+worm gear+gear) of original PW exposed gear case is reduced to the rack pinion transmission, and transmission is accurately steady, and the instantaneous angular velocity of chute rotation axis is constant, improves transfer efficiency.The selection of tooth bar position is help whole hoisting appliance stressed, cylinder rod withdrawal when promptly chute upwards fascinates, and cylinder rod, intermediate draw bar, tooth bar all are subjected to pulling force; Cylinder rod stretched out when chute fascinated downwards, and cylinder rod, intermediate draw bar, tooth bar help chute to fascinate under the effect of stand and chute gravity downwards.Therefore whole stressed the stable of leverage that help.
Rotatablely moving is single train of wheels transmission, and the center of gravity of the major parts that rotatablely moves is substantially at the housing center, and it is comparatively steady therefore to rotatablely move.
The driving of moving of fascinating is 3 oil cylinders, and hydraulic pressure adopts the closed-loop control servosystem, makes the oil cylinder synchronized movement.In order to prevent the beat of lifting stand, 3 groups of guide deflection sheaves are installed on the lifting stand, the lifting stand can only be moved up and down along track; Each guide deflection sheave in 3 groups of guide deflection sheaves is the excentric shaft design, the convenient gap of adjusting with guide rail.The rack pinion transmission is accurately steady, changes three grades of transmissions (gear+worm gear+gear) of PW into single-stage, has reduced the accumulation of backlash, has improved transmission accuracy.The instantaneous angular velocity of chute transmission shaft is constant, has avoided the crank drive slippage in the horizontal direction of domestic other distributors, causes the unstable and chute wearing and tearing of the speed of fascinating.For the sector wheel and rack is effectively meshed, do not occur stuck or skew, tooth bar is connected with stand and is designed to oscillating bearing, and tooth bar design has flange and gear applying, adds upper rack contact roller device, has guaranteed the engagement of tooth bar and toothed segment.
The rotation of chute and the transmission of fascinating control are independent fully, do not interfere each other, but both individual drive, also transmissions simultaneously.The VVVF speed control by frequency variation is adopted in the chute rotation, can regulate the speed according to the size of technology cloth ring, and the even cloth of material is fallen in the stove.Use encoder control to understand the position of rotation of distributor chute at any time.The chute oil cylinder that fascinates is installed built-in position transducer, and the synchronization action of control oil cylinder reflects the turning angle of chute simultaneously.The maximum turning angle needs of chute are only satisfied in oil cylinder lifting travel design, so sharpest edges are to make chute surpass the turning angle scope, control malfunctioningly also can not cause the accident.
Distributor adopts recirculated cooling water to carry out the cooling of heating part.All be furnished with the multichannel water-cooled tube in heating part (rotator) inboard, current flow to the bottom water leg by the top water leg through cooling tube, discharge then.All be coated with in the outside of heating part in addition and be covered with insulating refractory.Add and in casing, carry out inflated with nitrogen that nitrogen pressure plays dustproof cooling a little more than furnace top pressure to box house.General effect reaches normally the box house temperature, helps the works better of gear, bearing.
Compact construction of the present invention, flexible movements, mechanism are reliable.Adopt the motor transmission to drive the chute rotation, the Driven by Hydraulic Cylinder chute fascinates, and has stability preferably, is easy to control.The entire operation process realizes by setting program control, satisfies the requirement of technology cloth track.Can be used for various blast furnace engineerings.
