本考案は、蒸気タービンのノズルダイアプラムを受ける
ノズルダイアフラム受台に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a nozzle diaphragm pedestal for receiving a nozzle diaphragm of a steam turbine.
蒸気タービンにあってはタービンの営業運転に入ってか
らたとえば２年毎に定期検査を行うのが通例になってい
る。For steam turbines, it is customary to perform periodic inspections, for example, every two years after the turbine begins commercial operation.
定期検査の場合、タービンの上半車室を取外しノズルダ
イアプラム上半を取外してタービン各部の点検を行う。For regular inspections, the upper half of the turbine is removed, the upper half of the nozzle diaphragm is removed, and each part of the turbine is inspected.
このとき取外した車室、ノズルダイアフラムは建通内の
クレーンの可動範囲の関係上、タービン本体の近傍のタ
ービン運転床面に並べられている。The casing and nozzle diaphragm that were removed at this time were lined up on the turbine operating floor near the turbine body due to the movable range of the crane in the building.
ノズルダイアプラムの並べ方は第１図に示すようにまく
ら木２をノズルダイアフラム１の下に敷いている。The nozzle diaphragms are arranged by placing sleepers 2 under the nozzle diaphragms 1 as shown in FIG.
一方、最近の蒸気タービンは容量的に増加の一途をたど
り、たとえばＩ１００ＭＷ級の原子力タービンのノズル
ダイアフラムの総個数は約７ｃＮＭにおよび、ノズルダ
イアフラムを第１図のように並べると膨大なスペースを
必要とし、その為にタービン建屋を計画する場合このス
ペースを考慮に入れなければならない。On the other hand, the capacity of modern steam turbines continues to increase.For example, the total number of nozzle diaphragms in an I100MW class nuclear power turbine is approximately 7 cNM, and arranging the nozzle diaphragms as shown in Figure 1 requires an enormous amount of space. Therefore, this space must be taken into account when planning the turbine building.
またノズルダイアプラムの各部を点検する場合、第１図
のように置くと裏側が点検出来ず、この面を点検するた
めに反転する必要がある等の種々支障をきたしている。Furthermore, when inspecting each part of the nozzle diaphragm, if the nozzle diaphragm is placed as shown in FIG. 1, the back side cannot be inspected and it is necessary to turn the nozzle diaphragm upside down to inspect this side, which causes various problems.
そこで本考案は、定期検査時等タービンを分解する際の
ノズルダイアフラムを並べて置くスペースの減少を図る
と共に、ノズルダイアフラムの各部を点検できるように
したノズルダイアフラム受台を提供することを目的とす
る。SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a nozzle diaphragm holder that reduces the space required to line up nozzle diaphragms when disassembling a turbine during periodic inspections, and also allows inspection of each part of the nozzle diaphragm.
以下、本考案の一実施例を第２，４図を参照して説明す
る。An embodiment of the present invention will be described below with reference to FIGS. 2 and 4.
第２図は本考案に係るノズルダイアフラム受台の平面図
を示すものであって、符号１３は受台を示し、この受台
１３は中央が挟まり、端面に向うにしたがって、撚目す
るよう機枠によって構成されている。FIG. 2 shows a plan view of the nozzle diaphragm holder according to the present invention, and reference numeral 13 indicates the holder, and this holder 13 is designed so that it is sandwiched in the center and twisted toward the end face. It is made up of frames.
また、この機枠の下面は、一つが横梁７ａによって囲ま
れた盲部１４を有する一方、これと隣り合せの部位短粱
７ｂによって囲まれノズルダイアプラムを載置した際そ
の内部が点検できるよう開口部１５を形成している。In addition, the lower surface of this machine frame has a blind part 14, one of which is surrounded by a cross beam 7a, and an adjacent part surrounded by a short part 7b, so that the inside can be inspected when the nozzle diaphragm is placed on it. An opening 15 is formed.
このような構成は互い違に配置されている。Such configurations are arranged in a staggered manner.
一方、前記盲部１４の縁部からは、張出された横支柱６

この横支柱６にステップ台８が載置され、このステップ
台８は第３図示の主縦支柱１０によって支えられている
。On the other hand, from the edge of the blind portion 14, a horizontal support 6 is extended.
is stretched to match the shape of the nozzle diaphragm,
A step stand 8 is placed on this horizontal support 6, and this step stand 8 is supported by a main vertical support 10 shown in the third figure.
さらに、盲カバ一部１４の適宜な位置には補助縦支柱９
が垂設される。Further, auxiliary vertical supports 9 are provided at appropriate positions on the blind cover part 14.
is installed vertically.
第３図および第４図は、受台１３にノズルダイアフラム

よび補助縦支柱９の端面には、平板５、支持受４を通し
て緩衝材３、例えば薄板ゴムがそれぞれ設けられており
、これらの構成部材によってノズルダイアフラム１が載
置されている。3 and 4 show the state in which the nozzle diaphragm 1 is placed on the pedestal 13, and the end faces of the horizontal support 6 and the auxiliary vertical support 9 are provided with a flat plate 5 and a support receiver 4 for cushioning. A material 3, for example a thin rubber plate, is provided, and the nozzle diaphragm 1 is mounted by these components.
なお、図中、符号１６は手摺を、また符号１０．１１は
ノズルダイアフラム１を構成する内輪をそれぞれ示す。In the figure, reference numeral 16 indicates a handrail, and reference numerals 10 and 11 indicate an inner ring constituting the nozzle diaphragm 1, respectively.
本考案は、上記のように構成したから、本考案によれば
タービンの分解組立時において一時的にノズルダイアフ
ラムを置くために使用しノズルダイアプラムを立てかけ
