Description
【０００１】
【発明の属する技術分野】
本発明は、タービン（蒸気タービン，ガスタービンのいずれの場合も含む）・発電機の搬送・現地据付方法に関する。
【０００２】
【従来の技術】
従来の火力，原子力発電プラントのタービン・発電機等の回転機械の現地での組立・据付においては、タービン及び発電機をそれぞれ単独で、あるいは共通台板上に一体化した状態で現地に搬入していた。
【０００３】
現地搬入後は、図３に示すように現地で建設された基礎架台であるコンクリート製タービン架台５１上にタービン５２及び発電機５３を据付け、その周囲にメンテナンスラックや配管ラック５４等を組立てて据付工事を完成させるのが一般的であった。
【０００４】
このようなコンクリート製基礎架台は、高調位型と呼ばれるもので、堅固に作られており、固有振動数が高く、回転体の固有振動数がそれ以下になるように設計されている。
【０００５】
【発明が解決しようとする課題】
従来のタービン発電機の現地据付において、タービン及び発電機の基礎架台は、前述したようにコンクリート製で高調位型のものであり、高剛性かつ堅固に設計されているため、体積が大きくなり重量も極めて重かった。
【０００６】
このため、タービン及び発電機は現地に別々に、あるいは共通台板上に組立てて発送され、現地に建設された基礎架台上に調整しながら据付けることが必要であり、基礎工事費、据付工事費が嵩む上に工期も長くなっていた。
本発明は上記の課題を解決しようとするものである。
【０００７】
【課題を解決するための手段】
請求項１に記載の発明に係るタービン・発電機の搬送・現地据付方法においては、基礎架台を、その固有振動数が組み付けるタービンおよび発電機の固有振動数以下である低調位型鋼製基礎架台とし、同基礎架台を工場にて組立て、これに前記タービンおよび発電機を組付けたのち、同タービンおよび発電機を前記基礎架台とともに現地へ発送し、現地にてそのまま据付けることを特徴としている。
【０００８】
上記において、タービン及び発電機を組付ける基礎架台は、従来の高調位型コンクリート製基礎架台に替えて、その固有振動数が組み付けるタービンおよび発電機の固有振動数以下である低調位型鋼製基礎架台を用いるものとしたため、重量の大幅軽減が可能となる。
【０００９】
そのため、工場内でタービンと発電機を基礎架台に組付けて一体とし、この一体化された状態で現地まで搬送し、そのまま据付けることが可能となり、工事費の大幅低減と工期の大幅短縮が可能となる。
【００１０】
【発明の実施の形態】
本発明の実施の一形態に係るタービン・発電機の搬送・現地据付方法について、図１及び図２により説明する。
【００１１】
図１及び図２に示す本実施形態に係るタービン・発電機の搬送・現地据付方法においては、予め、工場内で低調位型鋼製基礎架台１を製作し、この基礎架台１上にタービン２及び発電機３を組付けて一体化する。
【００１２】
次に、基礎架台１とタービン２と発電機３を一体化した状態で工場から現地まで海上輸送し、現地構内をトレーラ４に搭載して搬送した後、現地の据付場所でトレーラ４を引き出すことにより、一体とした基礎架台１とタービン２と発電機３の据付けを完了する。
【００１３】
上記において、低調位型鋼製基礎架台１は、その固有振動数をタービン２及び発電機３の固有振動数以下として柔軟に設計されており、鋼製のため、従来のタービン発電機の据付けにおいて用いられていたコンクリート製基礎架台に比べて大幅に重量が軽減されるとともに、工場製作が可能となった。
【００１４】
そのため、工場にて基礎架台１とタービン２と発電機３を一体化し、そのまま現地へ搬送し、そのまま据付けることができ、基礎工事費、据付工事費の大幅低減が可能となり、工期の著しい短縮が可能となった。
【００１５】
【発明の効果】
本発明のタービン・発電機の搬送・現地据付方法においては、タービン及び発電機を搭載する基礎架台として、その固有振動数が組み付けるタービンおよび発電機の固有振動数以下である低調位型鋼製のものを工場内にて製作し、この基礎架台の上にタービン及び発電機を工場内で組付けて一体とした後、そのままの状態で現地まで搬送し、現地据付を行うものとしたことによって、基礎架台の重量が従来のものに比べて大幅に軽減され、タービン、発電機及び基礎架台の一体搬送、一体現地据付が可能となったため、基礎工事費及び据付工事費の大幅低減と工期の大幅短縮が可能となる。

BACKGROUND OF THE INVENTION
The present invention relates to a method for transporting and installing a turbine (including steam turbines and gas turbines) / generators.
[0002]
[Prior art]
In conventional thermal power and nuclear power plant turbine / generator rotating machinery such as on-site assembly / installation, the turbine and the generator are each carried alone or integrated on a common base plate. It was.
[0003]
After the delivery to the site, as shown in FIG. 3, the turbine 52 and the generator 53 are installed on the concrete turbine platform 51 which is a foundation platform constructed locally, and a maintenance rack, a
[0004]
Such a concrete foundation is called a harmonic type, is made firmly, has a high natural frequency, and is designed so that the natural frequency of the rotating body is lower than that.
[0005]
[Problems to be solved by the invention]
In the conventional on-site installation of turbine generators, the turbine and generator foundations are made of concrete and are of high-order type, as described above, and are designed to be rigid and solid, which increases the volume and weight. Was also very heavy.
[0006]
For this reason, turbines and generators must be installed separately on site or assembled and shipped on a common base plate, adjusted and installed on the foundation frame constructed locally. The cost was high and the construction period was long.
The present invention seeks to solve the above problems.
[0007]
[Means for Solving the Problems]
In the turbine / generator transport / on-site installation method according to the first aspect of the present invention, the foundation frame is a low-adjustment type steel foundation frame whose natural frequency is equal to or less than the natural frequency of the turbine and the generator to be assembled. and then, assembling the same basic frame at the factory, after assembly the turbine and generator to, ships of the same turbine and generator to local together with the basic frame, and characterized as installing it on site .
[0008]
In the above, the foundation frame for assembling the turbine and the generator is replaced with the conventional harmonic concrete foundation frame, and the low-grade steel foundation whose natural frequency is equal to or less than the natural frequency of the turbine and generator to be assembled. Since the platform is used, the weight can be greatly reduced.
[0009]
As a result, the turbine and generator can be assembled and integrated into the foundation frame in the factory, transported to the site in this integrated state, and installed as they are, greatly reducing construction costs and construction time. It becomes possible.
[0010]

In the turbine / generator transport / on-site installation method according to the present embodiment shown in FIGS. 1 and 2, a low-adjustment type steel foundation gantry 1 is manufactured in advance in a factory, and a turbine 2 is mounted on the foundation gantry 1. And the
[0012]
Next, the foundation gantry 1, the turbine 2 and the
[0013]
In the above, the low-alignment type steel foundation gantry 1 is designed flexibly so that its natural frequency is less than or equal to the natural frequency of the turbine 2 and the
[0014]
Therefore, the foundation gantry 1, turbine 2 and
[0015]
【The invention's effect】
In the method of transporting and installing the turbine / generator according to the present invention, as a foundation frame on which the turbine and the generator are mounted , the natural frequency of the turbine / generator to be assembled is a low-adjustment type steel that is equal to or less than the natural frequency of the turbine / generator . By manufacturing things in the factory, assembling and integrating the turbine and generator on the foundation frame in the factory, they were transported to the site as they were, and installed on site. The weight of the foundation gantry is greatly reduced compared to the conventional one, and the turbine, generator and foundation gantry can be transported together and installed on-site. Shortening is possible.
