Description
Technical field
The present invention relates to belong to building of nuclear power station construction site technical field, and in particular to a kind of nuclear power plant shields door frame
Mounting tool.
Background technology
Nuclear power plant refers to nuclear energy being converted to thermal energy, and to produce the steam for steam turbine, steam turbine drives power generation again
Machine, constitutes the power plant for producing commercial power.Nuclear power plant uses the fission reaction of uranium or plutonium, the reality of this fission reaction
Border mass-energy conversion proportion is very low, but the energy after being converted due to material is very big, also very efficient a kind of mode at last.By original
The nuclear energy of daughter nucleus fission release is changed into the system and equipment of electric energy, and commonly referred to as nuclear power station is also referred to as atomic power station.Core fires
The energy that material fission process discharges, by the cooling agent circulated in reactor, takes energy out of and is transferred to boiler generation
Steam is driving turbine and drive electrical power generators.Nuclear power is the boiler that thermal power station is replaced with nuclear reactor, is fired with core
" burning " for expecting special shape occurs in nuclear reactor produces heat, is allowed to become steam to heat water.Steam passes through pipeline
Into steam turbine, steam turbine generator power generation is promoted.It is, in general, that the steam turbine generator and electrical equipment of nuclear power station and common thermoelectricity
Stand similar, its profoundness essentially consists in nuclear reactor.Nuclear power station is except key equipment -- in addition to nuclear reactor, there is many therewith
The important equipment of cooperation.By taking pressurized-water reactor nuclear power plant as an example, they are main pumps, voltage-stablizer, steam generator, containment, steamer hair
Motor and critical cooling system etc..They have respective specific function in nuclear power station.
Nuclear power plant's shield door is in inside nuclear island, since its door opening is big, tonnage weight, Contraction in Site space in addition
Limited, the medium-and-large-sized lifting equipment of installation process can not realize that disposable lifting is in place, only manually carry and carry out mounting and adjusting,
Cause difficulty of construction big, dangerous matter sources are more, and construction cost is high.
The content of the invention
The technical problems to be solved by the invention are the doorframes of existing nuclear power plant's shield door since construction environment can not use
