Mounting system for a gas turbine, and associated gas turbine
A mounting system for a gas turbine, includes two rails, on each rail a fastening portion for fastening the rail on a manhole of the gas turbine, and for each rail at least one displacement element, which can be displaced along the rail. With the aid of such a mounting system, maintenance tools and/or turbine components are straightforwardly passed through a manhole and displaced to their location of use.
1. A mounting system for a gas turbine, comprising:
two units which can be connected to each other,
wherein each unit has a rail, a fastening section in the shape of a segment of a circle, on the rail, for fastening the rail to a manhole of the gas turbine,
at least one displacement element per rail, which can be displaced along the rail, and
two cross-struts which extend transversely with respect to both rails and interconnect the rails.
2. The mounting system as claimed in claim 1 ,
wherein both units have an identical construction.
3. The mounting system as claimed in claim 1 ,
wherein each cross-strut is hinged on one of the rails.
4. The mounting system as claimed in claim 1 ,
wherein abutment elements for supporting the rails on a turbine housing are provided at ends of the rails.
5. The mounting system as claimed in claim 1 ,
wherein two displacement elements which can be interconnected via a safety device are provided per rail.
6. A gas turbine comprising:
the manhole formed on an outer housing of the gas turbine, and
the mounting system as claimed in claim 1 ,
wherein the manhole has a flange on its circumference and
wherein the fastening sections are connected detachably to the flange in such a way that the rails with the displacement elements extend in the interior of the gas turbine.
7. The gas turbine as claimed in claim 6 ,
wherein a radius of the segment of the circle of the fastening section corresponds essentially to a radius of the flange of the manhole.
8. A mounting system for a gas turbine, comprising:
a first unit comprising: a first fastening section comprising a plurality of first bolt holes therethrough and arranged in a first arc; a first rail; and a first connector bar configured to hold the first rail apart from the first fastening section; and
a second unit comprising: a second fastening section comprising a plurality of second bolt holes therethrough and arranged in a second arc; a second rail; and a second connector bar configured to hold the second rail apart from the second fastening section;
wherein when the first fastening section and the second fastening section are arranged such that the first arc and the second arc form a circle, the first connector bar and the second connector bar are disposed radially within a cylinder defined by the circle and position the first rail and the second rail parallel to each other and transverse to the cylinder.
9. The mounting system as claimed in claim 8 , further comprising a displacement element configured to move along the first rail.
10. The mounting system as claimed in claim 8 , wherein when the first fastening section and the second fastening section are arranged such that the first arc and the second arc form the circle, the first fastening section and the second fastening section are configured to abut a flat end-surface of a circular manhole opening flange.
11. The mounting system as claimed in claim 8 , further comprising two cross-struts which extend transversely with respect to both rails and interconnect the rails.
12. The mounting system as claimed in claim 11 , wherein the two cross-struts are pivotally mounted to respective ends of the first rail.
