Problems solved by technology
In this way, the water guide tile weighing 300 catties must be lifted out from the oil tank to the top cover of the oil tank. Sliding in a lower direction or a direction with weaker strength, people in a lower position will not be able to bear all the weight, which may cause personal safety accidents, and may also crush water guide pads, shaft collars and other components, which will affect the quality of maintenance and maintenance. Maintenance efficiency

The invention discloses a water turbine guide bearing lifting device, which comprises a base, a support frame, a guide wheel, hoisting equipment and a steel wire rope, wherein the support frame is arranged on the flange surface of an oil tank through the base, the guide wheel is arranged at one side, near a water turbine guide bearing, of the support frame, the hoisting equipment is arranged at the other side of the support frame, one end of the steel wire rope is connected with the hoisting equipment, the other end of the steel wire rope is steered by the guide wheel and is then connected with the water turbine guide bearing, and the hoisting equipment drives the steel wire rope to drive the water turbine guide bearing to lift when the hoisting equipment is started. The lifting device has the advantages that the structure is simple, the operation is convenient, the safety is high, and the overhauling efficiency and overhauling quality can be effectively improved.
Description
technical field [0001] The invention mainly relates to the overhauling technology of a mixed-flow hydroelectric generator set, in particular to a water guide tile lifting device. Background technique [0002] Francis hydro-generator set, with a single unit capacity of 240MW, and the generator is a vertical half-umbrella structure. The generator shaft has three sections (including the rotor center body), which are connected with the Francis turbine main shaft through flanges. The shaft system of the unit is supported by two radial positions, that is, the upper guide of the generator and the guide bearing of the water turbine. The upper guide shaft is installed in the center body of the upper frame. The guide bearing of the water turbine is supported by a wedge plate. It is composed of seat, adjustment device, cooler, oil retaining barrel and oil basin and other components. The water guide tile is an oil-immersed self-circulating Babbitt tile structure, 10 pieces per machine...
