The specific embodiment
1, among Fig. 1 and Fig. 2, can be according to the maximum package tonnage of ladle turret, two overhead traveling crane end positions, the box type structure girder of design corresponding size specification carries out each component processing of suspender then and makes.
2, Shoudu Iron and Steel Co capital Tang first stage of the project continuous casting main building column six-column seven and column eight-column nine need to install two 2150 conticasters, two ladle turrets lay respectively at F and stride between column six-column seven and column eight-column nine lines, about 410 tons of every ladle turret gross weight.Before suspender uses, suspender is tested for 1.25 times by the maximum nuclear that carries of design, checked, can satisfy operating needs to determine it according to the hoisting crane acceptance specification.
3, among Fig. 3, about 32 tons of base and axis of revolution load-bearing, before the lifting, arrange 30 groups of adjusting blocks, to grind centering, extract 8 groups then out, base suspender hoisted in position. the coaster two ends are fixed with the 10T chain block and are regulated base and wear anchor (bolt) hole, two overhead traveling crane drivers listen lifting unified command, the two overhead traveling cranes hook amplitude of having walked to be not more than 300mm. during lifting
4, base in place after, carry out bolted, the bolt of lower base tightening sequence is carried out foreign side's handbook regulation, use the drawbench binding bolt, tightening bolt must be undertaken by cornerwise order, divides and carries out for three times, tighten to 1/3 of prescribed torque for the first time, tighten to 1/2 of prescribed torque for the second time, tighten the moment of torsion that reaches the drawing technical requirements for the third time, eventually tight power is 1190KN.The T2 transit survey is adopted at the center in length and breadth, and level, absolute altitude adopt the indium steel ruler to measure, and observed reading five equilibrium on the gear ring face is got 8 points, levelness 0.05mm/m.
5, after the base centering, carry out gyro-rotor lifting, during the steel rope wire rope handling one four strands, will put contact and become the line contact, promptly concentrated load becomes uniform load, improves like this to lift safety factor.Two overhead traveling crane drivers listen lifting unified command, the two overhead traveling cranes hook amplitude of having walked to be not more than 300mm during lifting, see Fig. 4.
6, gyro-rotor in place after, according to foreign side's technical requirements, to ladle turret bull gear bolted, fastening force 800KN.By foreign side's personnel inspection bolt tension length, after the gyro-rotor acceptance(check), carry out slewing frame and install.Gyro-rotor lifting (see figure 5), the time two overhead traveling crane drivers listen the lifting unified command, the two overhead traveling cranes hook amplitude of having walked is not more than 300mm.It is to wear bearing pin Φ 300 (how to guarantee the concentricity in bearing pin and hole during gap 0.056～0.189mm) that slewing frame is installed main difficult point.Can use the frame level visual control, coating butter on bearing pin reduces the resistance in the process of walking.
7, after ladle turret base, gyro-rotor, slewing frame lift, utilize 80 ton overhead travelling cranes to hold in the palm back stall and forks arm assembling (see figure 6), each about 53 tons, utilize 480/80 ton overhead travelling crane integral hoisting, when noting lifting, that end jack of holding pin is low, whole arm angle at 45 approximately, whole forks arm oblique cutting is gone into slewing frame, is beneficial to like this to wear the maintenance holding pin.
8,160 tons of production overhead traveling cranes have been liberated in the installation of preceding base, gyro-rotor, slewing frame, and holder back stall and yoke lifting are finished and liberated 480/80 ton overhead travelling crane, have guaranteed to produce and have carried out smoothly.Remaining part such as oil cylinder, actuating device, slip ring, platform stair etc. do not need to take the production overhead traveling crane, all can utilize ladle turret top 10T maintenance cucurbit to install.
9, after overall package is finished, carry out hydraulic piping, power transmission debugging.
