Description
Technical field
The utility model is related to Heavy Equipment-hoisting technical fields, and in particular to a kind of thermal power generation unit tower boiler is hung
Fill mechanical arrangement structure.
Background technology
Electric power is the important energy source of the national economic development, and thermal power generation is China and many countries produce electric energy in the world
Main method.Thermal power generation carries out capital equipment --- boiler, steam turbine and the generator of energy conversion, and it is big main to be referred to as three
Machine, and boiler is then energy conversion most basic in three big hosts.Boiler plant quantity is more, weight is big, it is therefore desirable to match somebody with somebody
Put special hoisting machinery.
Currently used lifting machine allocation plan is in a stove left side or the one large-scale derrick crane of the right arrangement of stove, the machinery
It is responsible for boiler plant lifting, when later stage board roof hoisting calls in a giant caterpillar formula crane and carries out cooperation lifting temporarily again.
But with the fast development of China's power industry, the single-machine capacity of thermal power project is increasing, and boiler components are hung
Fill that difficulty is also higher and higher, previous mechanical arrangements and Hoisting Program can not meet the installation requirements of current large sized unit.
The more conventional boiler height of thermal power generation unit tower boiler is high, weight of equipment is big, and the later stage is risen using giant caterpillar formula
When heavy-duty machine coordinates large girder and the lifting of other eminence large components, crawler crane is in sling height, rate of load condensate and mechanical resistance
It cannot be met the requirements in terms of bar, giant caterpillar formula crane can not be used.
Utility model content
The defects of in order to solve the prior art, the purpose of this utility model are to provide a kind of thermal power generation unit tower boiler
Lifting machine arrangement.
A kind of thermal power generation unit tower boiler lifting machine arrangement of the utility model, it is major-minor including being responsible for boiler
Steelframe is installed and tower crane I, the tower crane II of board roof hoisting, tower crane I and the cooperation of tower crane II complete the installation of boiler major-minor steelframe and
The lifting of large girder, the tower crane I are arranged in boiler furnace and are arranged in Boiler Furnace close to the one side of stokehold, the tower crane II
Outside, the one side after stove, III position of reserved tower crane on the right side of boiler, for installing boiler, remaining sets tower crane at III position of tower crane
Standby lifting work.
Further, the tower crane I and tower crane II are detachable tower crane, and boiler is completed in tower crane I and the cooperation of tower crane II
The lifting of major-minor steelframe, large girder, tower crane II can also complete the dismounting of tower crane I, and tower crane I is facilitated to be moved to III position of tower crane.
Further, the tower crane I and II same period of tower crane arrangement, are used cooperatively, and can facilitate the major-minor steelframe installation of boiler
And the lifting of large girder, it avoids and carries out large girder and the lifting of other eminence large components using giant caterpillar formula crane,
So as to which effectively overcome that crawler crane cannot meet the requirements in terms of sling height, rate of load condensate and mechanical resistance bar lacks
It falls into.
Further, at III position of tower crane tower crane be tower crane I, i.e., tower crane III for tower crane I dismounting after assemble again and
Into in this way, realizing the secondary use of tower crane I, saving machinery expenses, saved construction cost.
The advantageous effect of utility model：
1st, the thermal power generation unit tower boiler lifting machine arrangement and installation method of the utility model, using the same period
The lifting of the major-minor steelframe of boiler and large girder is completed in tower crane I and tower crane II cooperation of arrangement, is avoided big in existing hanging method
Plate-girder and other eminence large components must call in a defects of crawler crane is lifted temporarily when lifting, thus gram
Crawler crane has been taken cannot be met the requirements in terms of sling height, rate of load condensate and mechanical resistance bar the problem of.
2nd, the utility model proposes targetedly big machinery arrangement side for the lifting of thermal power generation unit tower boiler
Case, working region can meet the lifting demand of each component of tower boiler, using only two tower cranes, save substantial amounts of machinery
Expense has saved construction cost.
