室２を開放して行なわれていたが、車室２をその
つど開放する作業は大掛りで、非常に面倒な作業
であつた。 As shown in FIG. 1, a large number of stator blades 1 of a turbine are installed on the inner circumferential surface of a casing 2. For example, in the case of a gas turbine, dust in the gas adheres to the stator blades 1, so the stator blades 1 are installed periodically. It is necessary to inspect the stationary blade 1 and remove any deposits. However, when inspecting the stator vane 1, it is not possible to do so from the outside, and therefore conventionally the casing 2 has been opened.However, opening the casing 2 each time is a large-scale and extremely time-consuming task. It was a tedious task.
そこで、本考案は上記欠点を解消し得るタービ
ン静翼を提供することを目的とする。 Therefore, an object of the present invention is to provide a turbine stationary blade that can eliminate the above-mentioned drawbacks.

し可能に取付けたものである。 That is, a hole is bored at a predetermined location on the annular edge of the exhaust port side of the vehicle compartment into which at least one stationary blade can be inserted from outside the vehicle compartment, and a stepped recess is formed around the outside of this hole. A holding plate that holds the stator vane inserted into this hole is removably attached to the stepped recess via a bolt.
かかる構成によると、少なくとも１個の静翼を
車室外周部から取外すことができるので、容易に
車室内全体の静翼へのダスト付着状態を知ること

放作業はしなくて済む。 According to this configuration, at least one stator vane can be removed from the outer periphery of the passenger compartment, so it is possible to easily check the state of dust adhesion to the stator vanes throughout the passenger compartment, thus eliminating the need for conventional inspections. There is no need to open the vehicle compartment for this purpose.

りで回転自在に設けられた動翼である。 An embodiment of the present invention will be described below with reference to FIGS. 2 to 4. Reference numeral 11 denotes a casing in a gas turbine, for example, and a plurality of stator blades 12 are installed in double rows on the inner circumferential surface of the casing, and at least one stator blade 12A in the row on the exhaust port 13 side is installed in the casing. 11 is configured to be detachable from the outer circumference. That is, a hole 14 into which the stator vane 12A can be inserted is bored at a suitable position (a place where it is easy to operate) in the annular edge 11a on the exhaust port side of the casing 11, and a stepped recess 15 is formed around the outside of this hole 14. Stator blade 12A formed and inserted into this hole 14
A presser plate 16 for holding the holder is attached to the stepped recess 15 via bolts 17. Note that 18 is a pin for fixing the presser plate 16 and the platform portion 12Aa of the stationary blade 12A, and 19 is a cover for the presser plate 16, which is fixed to the annular edge 11a of the compartment 11 with bolts 20. Further, reference numeral 21 denotes a rotor blade which is located between each of the 12 rows of stator blades and is rotatably provided around the rotor axis A.

分な車室１１の開放作業をしなくても済む。 In the above configuration, when inspecting the stationary blades 12 inside the casing 11, first remove the cover 19, then remove the presser plate 16 from the annular edge 11a, and then
Pull out one stationary blade 12A inside. And this stationary wing 1
By inspecting 2A, it is possible to know the state of dust adhesion on the stationary blades 12 in the entire vehicle interior 11, and there is no need to perform unnecessary work to open the vehicle interior 11 as in the conventional case.
