Abstract

The invention relates to a maintenance platform based on magnetorheological fluid, which includes a frame-shaped scaffold arranged outside the main shaft and a lifting platform horizontally arranged in the scaffold; the scaffold includes a horizontal base and is vertically fixed on the The uprights at the upper ends of the four corners of the base and the push rods horizontally fixed on the upper ends of the uprights; the outer side of the lifting platform is slidably sleeved on the uprights; the scaffold is provided with a driving mechanism; the driving mechanism and the lifting platform connected to drive the lifting platform up and down along the column; the inside of the lifting platform is horizontally fixed with a rubber pedal; the inside of the rubber pedal is hollow and the inner cavity is filled with magnetorheological fluid; a coil is embedded in the rubber pedal; The coil can be electrically connected to an external power supply; when the coil is energized, the magnetorheological fluid in the rubber pedal changes from liquid to solid state due to the change of the magnetic field, which can realize the curing of the rubber pedal.

Description

technical field [0001] The invention relates to a maintenance platform based on magnetorheological fluid, which belongs to the technical field of maintenance equipment in hydropower stations. Background technique [0002] The main shaft of the water turbine is the shaft of electric power, hydraulic machinery and auxiliary equipment, which connects the runner of the water turbine with the rotor of the generator and transmits the torque. The function of the main shaft of the water turbine is to transmit the mechanical energy converted by the water turbine to the generator, thereby driving the rotor of the generator to rotate, and at the same time bear the thrust of the water and the weight of the rotating part. The axis measurement and adjustment of the hydroelectric generating set is an important process in the maintenance of the hydroelectric generating set. The quality of the unit axis adjustment will directly affect the swing and vibration of the unit during operation, th...
