Product Description Product DescriptionLarge petrochemical storage tanks are usually constructed by lifting and flipping. The key to the inversion process is the lifting of the tank body, and there are many types of specific processes and supporting equipment.This paper mainly introduces the use of electric hoist group lifting inversion method in the manufacture of large storage tanks, using a new type of electric hoist as lifting equipment, and adding a fine-tuning circuit in the control system. The system has the advantages of smooth lifting, good synchronization, fast construction speed, low equipment cost, high efficiency, good safety self-locking function, easy installation quality control and so on. In the construction of large storage tank, this construction method has high popularization and application value.Low speed electric chain hoist parametersRated lifting capacity10 tonsLifting speed0.09min/meterLifting height4m-8mMotor modelYHPE-500Motor power500WMotor speed1380R/Minvoltage380VHoist modelHS10Total weight90-124KGElectric hoist flip method lifting storage tank schemeN sets of 5T-3M electric chain hoist are used in the storage tank. The maximum use of the 5-ton electric chain hoist is 60% of the maximum tonnage, that is, no more than 3 tons. The maximum travel of the electric chain hoist is 3 meters (the length can be customized).First, make the top first circle plate of the tank on the bottom plate, install the expansion ring on the first circle plate, the bottom surface of the expansion ring is about 200mm from the bottom edge of the first circle plate, and use a spiral jack to tighten the expansion ring on the first circle plate; Install lifting columns 400mm away from the inner wall of the tank, and arrange N lifting columns evenly around the inner circumference of the tank wall. Use two pull rods to make an eight-figure diagonal bracing support between the upper end of the column and the bottom plate of the tank, and then pull the two adjacent lifting columns together with pull rods to form a whole circle. Weld a lifting ear on the corresponding expansion ring of the lifting column. Weld a stop block on the tank wall at the upper end of the expansion ring to block the expansion ring, hang the electric chain on the lifting column on the top of the lifting lug, the hook of the electric hoist is hooked on the lifting lug of the expansion ring, install all the electric hoist in turn, connect the power cord of all the electric hoist to the total control table, the total control table can separately control each electric hoist, It can also be unified centralized synchronous control of all electric hods, turn on the total power supply, and then pre-tighten each electric hods, check whether the force of all electric hods is uniform, check whether all the lifting points are normal, if everything is normal, it can be lifted. The total console is adjusted to centralized control, and the overall rise button is connected, so that all the electric hods will rise together. If the electric hods do not make force during the rise, the total console needs to be converted to separate control, the loose electric hods are re-pre-tight and then the overall lift, until the elevation is raised to the specified height, and finally the height of the lift is adjusted by separate adjustment, and then the coaming board, After welding the vertical seam and welding the stop block, then lower all the electric hoist as a whole, so that the first circle plate falls back to the second circle plate on the circumference, so that the overall lifting of the first circle plate is completed; After the ring seam welding is completed, loosen the expansion ring, use the electric hoist to lower the whole expansion ring to the specified height of the second ring plate, and then prepare for the next lift.Major Component1 Motor8 Pin Bush15 Gear Piece22 Steel Bushing29 Down-hook Shelf2 Pin Gear9 Bearing Collar16 Spline Gear23 Guide Wheel30 Pulley3 Pin Wheel Housing 10 Bearing Collar17 Macroaxis24 Bolt31 Pulley axle4 Cycloidal Gear 11 Up-hook Beam18 Side Fascia25 Ring Shield32 Roller Pin5 Spacer Ring12 Lifting Hook19 Housing26 Lifting Chain33 Ring Shield6 Eccentric Bearing13 Lifting Chain Wheel20 Minor Axis 27 Baffle34 Down-hook Beam7 Hinge Pin14 Bracing Stick21 Pin Roller28 Lifting Chain Plate35 Chain Stopper Plate
