Device having a load arm for installing and removing a component of a gas turbine

Abstract

A device for installing and removing a component in a gas turbine, includes a rail system for fastening to the gas turbine, on which rail system at least one runner is provided, which can be moved along a predetermined movement axis. A load arm is fastened to the runner, which load arm is designed to be pivoted in at least two spatial directions, and wherein the load arm has a fastening segment, which is designed to form a detachable connection to the component in question. The load arm has three joints each having a defined pivot axis, of which pivot axes preferably at least two are parallel to each other, wherein the joints each have a pivoting resistance device, which pivoting resistance devices are designed to set the pivoting resistance of the respective joints.

         11 . A device for installing and removing a component of a gas turbine, comprising
 a rail system for attaching to the gas turbine, on which rail system there is provided at least one runner which can be displaced along a predetermined displacement axis, wherein a load arm is attached to the runner and is designed to be pivoted in at least two spatial directions, and wherein the load arm has an attachment section which is designed to establish a releasable connection with the relevant component,   wherein the load arm has three articulations each having one defined pivot axis, of which pivot axes all are mutually parallel, wherein the articulations each have a pivot-resistance device which are designed to set the pivot resistance of the respective articulation.   
     
     
         12 . The device as claimed in  claim 11 ,
 wherein the load arm has articulations which allow the load arm to be pivoted in exactly two spatial directions.   
     
     
         13 . The device as claimed in  claim 11 ,
 wherein one articulation is attached to the runner and the pivot axis of the articulation runs essentially perpendicular to the displacement axis.   
     
     
         14 . The device as claimed in  claim 11 ,
 wherein a first and a second articulation are connected to one another with a first connecting section, and the second and a third articulation are connected to one another with a second connecting section, wherein the two connecting sections provide different distances between the respective articulations.   
     
     
         15 . The device as claimed in  claim 14 ,
 wherein the attachment section is directly or indirectly fixed to the end of one of the articulations and a connecting section which is also fixed to the articulation in question is longer than the respective other connecting section.   
     
     
         16 . The device as claimed in  claim 11 ,
 wherein the articulations each have an immobilizing device which is designed to immobilize the respective articulation.   
     
     
         17 . The device as claimed in  claim 11 ,
 wherein the attachment section is directly or indirectly connected to one of the articulations.   
     
     
         18 . The device as claimed in  claim 11 ,
 wherein the attachment section is designed to be connected to the burner-side end of the relevant component.   
     
     
         19 . The device as claimed in  claim 11 ,
 wherein the attachment section has a lifting device.   
     
     
         20 . The device as claimed in  claim 19 ,
 wherein the lifting device is designed to move at least one part of the attachment section parallel to one of the pivot axes.   
     
     
         21 . The device as claimed in  claim 20 ,
 wherein the lifting device is designed to move at least one part of the attachment section parallel to the locally closest pivot axis.   
     
     
         22 . The device as claimed in  claim 13 ,
 wherein one articulation is attached to the runner in a fixed position.   
     
     
         23 . The device as claimed in  claim 18 ,
 wherein the attachment section is designed to be connected to the burner-side end of the relevant component to a transition piece.
