(4) After the thrust bearing bush is pulled out from the thrust bearing oil tank, the pull rod of the pull bush can be detached from the thrust bearing bush, and meanwhile, the hand rocker with internal threads can be detached from the pull rod of the pull bush, so that the push rod is convenient to use when the next thrust bearing bush is pulled out.

The utility model has simple principle and convenient manufacture and use. The thrust bearing oil tank is transferred to the outside of the oil tank by the work which does not accord with the man-machine efficiency, manpower and material resources can be greatly saved, and the phenomenon of popping up of the moving distance of the thrust bearing cannot occur, so that the thrust bearing oil tank is safe and reliable.

Meanwhile, the tile extracting tool of the thrust bearing tile of the hydroelectric generating set can be repeatedly used, one set of tile extracting tool can be matched with one set of tile extracting tool, and multiple sets of tile extracting tools can work simultaneously to accelerate the completion of the extraction and maintenance work of the thrust bearing tile.
