Packing technique field.
Background technology
Along with the fast development of China's power industry, high parameter, large sized unit have become as power industry trend and
Trend.At present, through introducing and digesting and assimilating, China has grasped large sized unit technology, and starts to produce supercritical in batches
600MW, the unit of ultra supercritical 1 000MW.Nearly ten years, the ratio shared by more than 600MW unit reached 40% with
On.By the end of the end of last year, have been put into 1 000MW unit of commercial operation more than more than 60 platforms, make China become hundred
The country that ten thousand kilowatts of unit owning amounts are most, maintains the leading position in the whole world.Due to large sized unit institute exclusive economy and
High efficiency, now has become as the main flow of Chinese large-sized coal unit.But, along with unit capacity increases, the thing followed is not only
The weight being only equipment is increasing, and the quantity of equipment increases the most significantly, seems especially prominent for boiler plant,
Also the boiler structural design machinery reasonable disposition of electric power construction unit is had higher requirement simultaneously.At present 600MW～
1000MW boiler plant lifts, and routine typically uses on the left of boiler or tower of right side layout one 80t～120t tonne
Heavy-duty machine is as main force's loop wheel machine, but depends a loop wheel machine alone and cannot cover whole boiler, completes the lifting task of all devices, still needs
Arranging that a 25t～50t tonne of derrick crane coordinates, the space arranged due to this crane limits, and can only be arranged in
Furnace roof, therefore referred to as furnace roof loop wheel machine.Because of the erect-position of furnace roof loop wheel machine, the installation of lower portion equipment usually can be affected, therefore this stove
Jack-up heavy-duty machine should possess walking in a horizontal state translation functions.Although what existing furnace roof crane had also carries a set of walking mechanism, but
Moving structure is complicated, and relatively costly, so needing to be improved this.
