Definitions

  • the invention relates to a mounting device for mounting a heat shield element, a method for mounting a heat shield element and a use of the mounting device with the mentioned in the preamble of each independent claims features.
  • High performance ceramic heat shields are used in many engineering applications to withstand temperatures up to 1600 degrees Celsius.
  • the heat shields of turbine engines such as gas turbines and turbine engines, such as those used in power-generating power plants and in larger aircraft, have correspondingly large shielded by heat shields surfaces inside their combustion chambers.
  • the shield must be composed of a plurality of individual ceramic heat shield elements spaced apart from one another with sufficient clearance. This gap provides the heat shield elements with sufficient space for thermal expansion.
  • a cooling fluid in the form of cooling air is blown through cooling passages as an effective countermeasure through the gaps in the direction of the combustion chamber.
  • This cooling air is also used to selectively blow the metal brackets, with which the ceramic heat shield elements (CHS, Ceramic Heat Shields) are clamped to the support structure, and thus to cool.
  • CHS Ceramic Heat Shields
  • brackets In order to carry out the brackets as simply and integrally as possible, a construction is known in which these brackets on the one hand in the support structure encircling circular and parallel groove inserted and on the other hand clamped with trained gripping portions in holder grooves be formed in lateral edges of the ceramic heat shield elements.
  • the heat shield elements are successively inserted with the holders in the grooves of the support structure, wherein the trailing elements obstruct the previously positioned in their positions.
  • a circular series of heat shield elements can be formed in a combustion chamber of a gas turbine.
  • the last remaining heat shield element can no longer be mounted in this way because the mutually present adjacent heat shield elements block a tangentially directed assembly movement.
  • a last heat shield element is referred to as a dummy plate or dummy. Consequently, solutions are used with screws for attaching the last heat shield element, which allow mounting of the heat shield element in the direction of the surface normal of the support structure.
  • a known screw used for this purpose four screws which engage in the recess formed in lateral edges of the heat shield element for this purpose.
  • This solution is often disadvantaged because the assembly brings a handling problem with it.
  • the handling of the four screws enforces, for example, the use of fixatives such as bonding or adhesive tape, which are not reliable, so that the screws can be lost and must necessarily be found because of high risk of damage.
  • an overhead mounting unfavorable because the screws can tilt by fixing with tape and thus can not be inserted into the holes provided. Since this is the last heat shield element, the screw can not be positioned by hand, but must be threaded into the holes using an Allen key - without sight.
  • EP 1 701 095 A1 and EP 0 558 540 B1 describe by way of example a heat shield as described above with the described advantages and disadvantages.
  • the heat shield elements are often referred to as stones and retaining elements holding them stone holder.

  • a frame is provided with means for holding four screwing tools and at least one holding device for holding the heat shield element to the frame, such that the position of the four screwing tools and at least one holding device with respect to each other is maintained.
  • the holding device for holding the heat shield element to the frame is designed as a suction cup with which a good suction connection can be achieved on the usually smooth surface of the heat shield element.
  • the holding device for holding the heat shield element to the frame can be firmly connected to the frame.
  • the holding device for holding the heat shield element to the frame with the frame can be connected in height adjustable. This allows an adaptation of the mounting device to the task.
  • At least one means for holding at least one screwing tool is designed to be rotatable and / or tiltable and / or translationally displaceable relative to the frame.
  • the means for holding at least one screwing tool is preferably designed as a ball joint, and the ball joint is acted upon by a defined predetermined stiffness or friction, whereby the screwing tool is flexibly adjustable and at the same time fixable in an reached position.
  • the mounting device according to the invention is adapted to mount existing dummy heat shield elements with four screw connections when four screwing tools are provided for four respectively corresponding fastening screws.
