Abstract
The invention discloses a kind of underground nuclear power station reactor building circular crane crossbeam hanging method, step is as follows: A, rock anchorage beam in reactor cavern, underground install annular construction bridge machine; B, gauntry crane hook one end of circular crane crossbeam, by circular crane crossbeam handling hanging in thing vertical shaft to underground reactor Mass Near The Top of Underground Cavity, and send in reactor cavern, underground by hanging thing vertical shaft; Lifting trolley on C, annular construction bridge machine puts down the other end that hoist cable hooks circular crane crossbeam, and lifting trolley moves along track to deviating from the direction of hanging thing vertical shaft subsequently, drives the other end of circular crane crossbeam upwards to rise and puts down to water rock anchorage beam gradually; D, gauntry crane and annular construction bridge machine coordinate the circular crane track girder being shelved on by circular crane crossbeam and being positioned at containment cylindrical shell top jointly.The invention solves because reactor cavern, underground limited space causes being difficult to the disposable difficult problem lifted by circular crane crossbeam, can technical field of nuclear power be widely used in.
Description
Technical field
The present invention relates to technical field of nuclear power, particularly relate to a kind of underground nuclear power station reactor building circular crane crossbeam hanging method.
Background technology
China proposes in " 12 " ENERGY PLANNING, accelerate to advance Construction of Nuclear Electricity.But under the impact of Fukushima, Japan nuclear incident, the global nuclear industry of just having come out of from the shade of Chernobyl has been absorbed in again low ebb.In view of this, country is more strict and prudent to the examination & approval of nuclear power projects, proposes higher safety requirements to nuclear power plant.So, by ground nuclear station all or the nuclear island part underground nuclear power station that is placed in underground be that nuclear power developing provides new thinking.
At present, the main hanging device in domestic nuclear power nuclear island all adopts circular crane, and the function class of its structure and realization seemingly.Ring hangs installation, debugs, tests and put into operation, be directly connected to the realization of multinomial engineering objective, as carrying out of the every construction in the installation of the visual plants such as dome lifting and fixing, reactor pressure vessel, steam generator, reactor building and the work such as system debug, preservice inspection.Meanwhile, " ring hangs available " itself is also one of key index of the construction of nuclear power station.After nuclear station business fortune, ring hangs and plays an important role to overhaul activities such as reactor pressure vessel open and close lids.
Circular crane comprises with lower component: 6 sections of track girders and 18 sections of rail, two you portion dollies, two crossbeams (electric beam and corresponding beam), bow member, operator's compartment, 217t/10t running trolley, 190t construction trolley, 5t driving (its track be suspended on two crossbeams under) and electric power and control system, wherein the heavyliest to count electric girder, weigh 79t, oad reaches 35.32m × 3.04m × 4.6m (long × wide × high), in traditional ground nuclear station, large-scale lifting appliance can be directly adopted to install from cylindrical shell top of not yet binding.And in underground nuclear power station, due to underground chamber limited space, cannot arrange that large-scale lifting appliance completes lifting from cylindrical shell is outside disposable.Therefore, be necessary to propose a kind of method that can lift circular crane crossbeam in limited underground chamber space.
Summary of the invention
The object of the invention is the deficiency in order to overcome above-mentioned background technology, a kind of underground nuclear power station reactor building circular crane crossbeam hanging method is provided, solves because reactor cavern, underground limited space causes being difficult to the disposable difficult problem lifted by circular crane crossbeam.
A kind of underground nuclear power station reactor building circular crane crossbeam hanging method provided by the invention, comprises the steps: A, rock anchorage beam in reactor cavern, underground to install annular construction bridge machine; B, gauntry crane hook one end of circular crane crossbeam, by circular crane crossbeam handling hanging in thing vertical shaft to underground reactor Mass Near The Top of Underground Cavity, and send in reactor cavern, underground by hanging thing vertical shaft; Lifting trolley on C, annular construction bridge machine puts down the other end that hoist cable hooks circular crane crossbeam, and lifting trolley moves along track to deviating from the direction of hanging thing vertical shaft subsequently, drives the other end of circular crane crossbeam upwards to rise and gradually to level; D, gauntry crane and annular construction bridge machine coordinate the circular crane track girder being shelved on by circular crane crossbeam and being positioned at containment cylindrical shell top jointly.
In technique scheme, in described step B, before gauntry crane hooks circular crane crossbeam, first with iant flat truck, circular crane crossbeam is transported to the hole of hanging thing vertical shaft.
Underground nuclear power station reactor building circular crane crossbeam hanging method of the present invention, has following beneficial effect: successfully solve the technical barrier installing the such as large-scale component that circular crane crossbeam is such in underground nuclear power station reactor building.
