STATOR-WINDING DISASSEMBLING DEVICE FOR DYNAMO-ELECTRIC MACHINE

PROBLEM TO BE SOLVED: To make it possible to perform the disassembling work of a stator winding safely using a light labor of a small number of persons by providing a wedge-shaped disassembling device, which pushes up the stator winding, a load suspending device and a carrier device. SOLUTION: The wedge-shaped tip part of a wedge-shaped disassembling device 14 is inserted into the end part side of the cut surfaces of an upper-side stator winding 4b and a lower-side stator winding 4a on the side of a turbine and on the side of a collector. The inserted wedge-shaped disassembling device 14 moves itself with a driving device 19, gradually advances toward the central part of an iron core from both end parts of the iron core and slowly draws the upper-side stator winding 4b from a slot. The drawn upper-side stator winding 4b is temporarily set in the hollow part in the stator core for the time being. Thereafter, the worker operates a load suspending device 20, moves the upper-side stator winding 4b on a carrier device 21 at the lower part of the stator core and carries out the winding 4b to the outside of the stator frame. Thus, the disassembling work of the stator winding can be performed safely using a light labor of a small number of persons.
