Description

A kind of boiler top crane integral translating method and less important work device
Technical field
The present invention relates to a kind of equipment and move operational method and apparatus, be specifically related to a kind of boiler top crane Walking in a horizontal state shift method and less important work device, be mainly used in power plant boiler equipment hoisting and transformation, belongs to boiler plant peace 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.
It is not found to have the patent literature constructed with the present invention by patent retrieval, has certain relation with the present invention Patent mainly have following:
1, Patent No. CN201420058741.0, entitled " a kind of horizontal type waste heat boiler interim boom hoisting of module furnace roof " Utility model patent, which disclose a kind of horizontal type waste heat boiler interim boom hoisting of module furnace roof, including upending frame, The shroud ring being connected equipped with beam hot with furnace roof on upending frame, shroud ring is also connected with left column and right column, at left column and right column Top equipped with cantilever beam, between two columns, be also equipped with the connection beam played a supporting role, in the bottom of cantilever beam equipped with hanging Ear.
