Gas turbine having a lifting mechanism
View Patent ↗A crane system having a gas turbine that has a manhole on the outer housing thereof, the manhole being designed to open up a maintenance access to hot gas parts of the gas turbine in the open state of the manhole, which is provided with a fastening section; the crane system further has a hoisting mechanism that includes a mating fastening section which is connected to the fastening section of the manhole in such a way that the hoisting mechanism introduces weights that same has to lift into the outer housing of the gas turbine.
1. A crane system comprising:
a combustion gas turbine comprising
an outer housing,
a plurality of burner openings in the outer housing, and
a manhole on the outer housing, the manhole comprising a fastening section; and
a lifting mechanism comprising
a mating fastening section,
a pillar, and
at least one boom arm,
wherein the mating fastening section of the lifting mechanism is configured to be connected to the fastening section of the manhole,
wherein, when the mating fastening section of the lifting mechanism is connected to the fastening section of the manhole, the lifting mechanism introduces weight forces onto the outer housing of the combustion gas turbine such that the weight forces are distributed onto the outer housing of the combustion gas turbine, and
wherein, when the mating fastening section of the lifting mechanism is connected to the fastening section of the manhole, the at least one boom arm is positionable above the plurality of burner openings in the outer housing.
2. The crane system as claimed in claim 1 ,
wherein the mating fastening section comprises a mating fastening section flange, and
wherein the fastening section comprises a fastening section flange configured to be screwed to the mating fastening section flange.
3. The crane system of claim 2 , wherein the fastening section flange has a thickened region via which the weight forces are further directed.
4. The crane system as claimed in claim 1 , wherein the manhole is arranged at a vertex of the outer housing.
5. The crane system as claimed in claim 1 ,
wherein the mating fastening section is fitted to one end of the pillar.
6. The crane system as claimed in claim 1 , wherein the lifting mechanism comprises at least two boom arms which comprise a pivotable design.
7. The crane system as claimed in claim 6 , wherein at least one boom arm of
the at least two boom arms comprises a multi-part design comprising individual parts,
wherein the individual parts are pivotable with respect to one another.
8. The crane system of claim 1 , further comprising:
the pillar secured to the mating fastening section, and
the boom arm pivotably secured to the pillar.
9. The crane system of claim 8 , wherein the boom arm comprises two boom parts pivotally secured to each other so that the two boom parts pivot about a vertical pivot axis.
10. The crane system of claim 1 , wherein the fastening section located on the outer housing is adapted to support loads to be lifted and is adapted to provide an introduction of force into a foundation upon which the combustion gas turbine is already positioned, wherein the foundation is designed for loading with large weight forces.
11. The crane system of claim 1 ,
wherein the at least one boom arm is pivotable on the pillar such that the at least one boom arm is positionable above the plurality of burner openings in the outer housing.
