Zusammenfassung: | The utility model provides a synchronous rising and falling device for a guide bearing oil pan of a hydro-generator, which is characterized by comprising a plurality of hydraulic jacks arranged below the guide bearing oil pan, and each hydraulic jack is connected with a synchronous flow dividing mechanism provided with a flow dividing valve through a pipeline provided with a throttling control valve. And the synchronous shunting mechanism is connected with the hydraulic pump station through a pipeline. Hydraulic oil sent out by the hydraulic pump station is shunted to each hydraulic jack through the synchronous shunting mechanism, and all the hydraulic jacks can synchronously ascend and descend under the dual guarantee of the synchronous shunting mechanism and the throttling control valve. The safety is greatly improved, potential safety hazards are avoided, meanwhile, the working efficiency can be improved, and consumption of human resources is reduced.
