Description

Large pressing machine parts hydraulic pressure lift slippage method and apparatus in place
Technical field
The present invention relates to a kind of hanging device and hanging method, particularly relate to a kind of lifting slippage Apparatus and method in place of large component.
Background technology
Large pressing machine is the strategic equipment that concerns national security, economic development, also is manufacturing basic equipment such as electric power, aviation, military affairs.China is as manufacturing powerhouse; No matter from international political relation and defense needs; Still from realizing the transformation level to power by equipment manufacture big country; Construction and introduction large pressing machine are all extremely urgent, and China will become the power of nuclear power, aerospace high-tech sector, just must equip the large pressing machine of oneself.
On this basis; Wuxi Turbine Blade Co., Ltd is from the German SMS introduction SPKA22400 of company clutch type screw press; Maximum hitting power reaches 3.5 ten thousand tons, is the maximum forging equipment of present hitting power in the world, is national key strategy equipment; It is installed to go into operation and can not only satisfy the needs of the super-huge blade of nuclear power, has also established solid foundation for the research and development production of Chinese large-sized aircraft High Performance forging.
For the installation of SPKA22400 clutch type screw press, because its complex structure, the single component Heavy Weight, setting accuracy is high, has therefore that difficulty of construction is big, requirements for quality is high and problem such as construction cost height.Improper like concept selection, construction quality, progress, cost etc. all are difficult for guaranteeing.
The SPKA22400 clutch type screw press; Form about 3000 tons of gross weight of equipment amount by backing-out punch, base plate, bench board, slide block, mother nut, upright arm, pull bar, driving screw, guide rail plate, bearing seat, lower pressure plate, friction lining, power-transfer clutch, flywheel, upward pressure plate, HM Hydraulic Motor etc. from bottom to up.Wherein entablatrance weighs 340 tons, and oad is 7.44m*4m*3.25m, and hoisting height is 12.2m, and base weighs 304 tons, and oad is 7.44m*4m*3m.Driving in the factory building is 160 tons; The ability that does not possess hoisted in position entablatrance and base; For the installation of this type of large pressing machine, the hoisted in position of base and entablatrance is crucial, generally adopts following three kinds of methods to lift; The one, adopt super-huge crane to install, the wheel crane of estimation needs more than 1500 tons could be with the entablatrance hoisted in position.The 2nd, lift with single masts of two 400 tons, when the entablatrance lifting altitude surpasses hoisting height, swing two single masts and make the entablatrance pendulum to upright arm top, fall in place again.The 3rd, make the gauntry crane that a crane capacity reaches 400 tons and carry out hoisted in position.
More than three kinds of methods have following problem: 1) the super-huge crane more than 1500 tons is at present domestic does not have, even have, it also is very high advancing appearance money and operating costs; 2) adopt second method, need to make 200 tons of masts of two long 20m, need 20 tons of large quantities of lifting tools such as winch in addition, the greatest problem of this method is that safety performance is bad, and winch, guiding slider and cable rope are difficult for being provided with and anchoring; 3) the third method need be made the gauntry crane of 400 tons of crane capacities, span 21m, and cost of manufacture is high, reclaims difficulty, is driven a vehicle simultaneously and makes the restriction of licence.

The 7th step: each main stressed place is provided with strain-gauge on elevator system, and wiring is connected with main control computer, and utilizes large-scale finite-element structure analysis program ANSYS software that the ess-strain monitoring information in lifting and the slipping is carried out computational analysis;
The 8th step: try to hoist, remove topside with ground-surface all be connected, check topside; And remove all load outside calculating; Check the service condition of whole elevator system, the overhead 100mm stagnation 2 to 3 hours that hoists is carried out end-to-end test to frock and lifting means afterwards;
The 9th step: formally lift by crane, pay close attention to according to the content in the 6th, seven steps when formally lifting;
The tenth step: carry out preparatory slippage, whether the joint of all valves or hard tube has loosening on the inspection hydraulic power unit; Whether the pressure spring of inspection by pass valve is in complete relaxation state; Inspection pumping plant control housing operating switch is in halted state; Loading is pressurised into 40%, 60%, 80% of required pressure at first according to hydraulic pressure creep machine, under all stable situation, can be added to 100%; After lifting fine strain of millet has begun that just displacement is arranged; Promptly temporarily stopping, whether normal, the situation of change of the fixing device of hydraulic pressure creep machine, sliding rail and machine frame if carrying out each equipment operation situation of end-to-end test then;
The 11 step: under all normal circumstancess, can formally begin slippage, undertaken by the tenth one step process during slippage, at first be hierarchical loading, in system, shows displacement and be advisable, and stops to load, and carries out formal slippage;
The 12 step: slide onto the installation site; Equipment is fallen after rise, because of the assembly precision of equipment own higher, so after equipment drops down onto the steady ring place; Modulated pressure crawl device and elevating ram carry out little all around to equipment; Adjust its levelness up and down, after everything is ready, elevating ram carried out falling equipment by 1~2mm/ at every turn synchronously;
The 13 step: equipment such as erection work platform steady ring, upright arm, slide block, mother nut, guide rail plate, driving screw, compensating cylinder, carry out the lifting of entablatrance afterwards, the lifting slippage of entablatrance is with regard to the same bench board of method for position; Carry out the installation of top equipment afterwards;
The 14 step: equipment debugging.
