Definitions

  • the present invention relates to an assembly platform for power plants, in particular for large steam turbines.
  • the manufacturer of the turbines already supplies cover plates or cover grids which have corresponding contours and fit on the turbine outer surfaces and which can be used for scaffolding erected around the turbine.
  • a multi-part and foldable stand surface is movably connected with foot parts and the individual base parts are attached to each other by hinges so that they can be folded one above the other.
  • the base which is movably connected to the foot parts, there is the advantage that the relatively large surface of the base surface can be folded into a space-saving package when not in use and the foot parts can also be folded onto it.
  • support brackets are provided for fixing the standing surfaces and struts on the turbine housing for supporting the foot parts.
  • Attaching support brackets and struts to the turbine housing enables the assembly platform to be easily attached without the need for additional scaffolding parts. This also makes it possible to determine the correct position for the subsequent installation of an assembly platform when making repairs or revisions, already when designing the turbine housing.
  • the standing surfaces consist of self-supporting honeycomb sheets, but they can also be formed from frame parts with gratings.
  • the standing surfaces with the foot parts are designed to be removable from the turbine housing.
  • a foot part which has a recess 2 on the lower edge into which a strut 3 fits and supports the foot part 1.
  • Standing surface parts 4, 4 1 , 4 are movably mounted at the upper end of the foot part 1.
  • Diagonal struts 5 are arranged between the foot part 1 and the standing surface 4, which serve to reinforce and stabilize the assembly platform.
  • the standing surface 4 rests on a support bracket 6, which, like the strut 3, is fastened to the turbine housing 7.
  • the standing surfaces 4 ', 4 lie in the folded position Condition on the stand area 4 and are connected to one another by hinges 8.
  • receptacles 9 are also provided for a folding railing 10.
  • FIG. 2 in which the same parts are provided with the same reference numerals as in Fig. 1, the assembly platform is shown in the unfolded state, the standing surfaces 4, 4 '4 "resting on the support brackets 6 on the turbine housing 7.
  • supports 11 are arranged for the standing surfaces, of which only the supports on the standing surface 4' are shown for the sake of clarity.
  • the standing surfaces 4, 4 ', 4" are turned on the support bracket 6 secured by bolts 12 against tipping.
  • Such supports 11 are particularly advantageous when the standing surfaces 4, 4 ', 4 "consist of weight savings from self-supporting honeycomb sheets.
  • the hinges 8 and, for example, anchors 13 can also be glued to the base surfaces 4, 4 ', 4 ", but it is appropriate to secure these bonds by screws, for example countersunk screws.
  • the multi-part assembly platform according to the invention which can be used in the folded state as a package by means of a crane in the open steam chamber between the outer and inner housing in steam turbines, and in which the opening between the Parts of the housing can be completely covered, it is possible to take up work for revision or repair work in the turbine within a very short time, with additional protection against accidents being achieved.
