Square to.
Vertical Spring vibration isolator includes several groups steel spiral cylinder spring, and along Foundation of Steam Turbogenerater top platen bottom
It is uniformly arranged.
Energy-consumption damper is set in Vertical Spring vibration isolator, and energy-consumption damper is symmetrically set along steam turbine generator axial centerline
It sets.
Foundation of Steam Turbogenerater top platen uses monolithic reinforced concrete structure.
Lower support structure is arranged in the lower section of shock isolating pedestal, and lower support structure uses monolithic reinforced concrete structure.
Compared with prior art, the present invention, which at least has the advantages that, can effectively reduce geological process to basic platform
The vibration of plate, and then reduction overall structure is influenced by earthquake；Wherein, vibration when spring reduction steam turbine operation, shock insulation branch
Seat is for reducing the vibration of earthquake bring；Industrial equipment vibration isolation and the earthquake under normal operation can be solved simultaneously
Earthquake motion shock insulation problem under effect；The large deformation problem being avoided that under equipment breakdown operating condition and larger earthquake operating condition.
The present invention can be under the premise of not influencing process pipe arrangement, by the way that shock insulation branch is arranged in spring vibration-isolator lower part
Seat reaches the vertical vibration equipment of isolation Foundation of Steam Turbogenerater top platen, by horizontal in basic top platen surrounding lateral arrangement
Limiting device is displaced to achieve the purpose that reduce foundation sole plate horizontal direction, to reduce foundation sole plate and surrounding floor or surrounding
The width of deformation joint between supporting structure, connection and reasonable arrangement of the present invention, excellent earthquake resistance, structure durability are good, later maintenance cost
Low advantage can be suitably used for the larger situation of Areas of High Earthquake Intensity area, pipe level active force and Turbo-generator Set high position arrangement
When spring vibration-isolated foundation.
Shock isolating pedestal uses lead rubber bearing, and lead for retractable pencil can absorb deformation well, absorbs energy.
Backing plate is set between shock isolating pedestal and Vertical Spring vibration isolator, is improved between shock isolating pedestal and Vertical Spring vibration isolator
The homogeneity of stress.
Further, the used flexible structure design of lower support structure, meets different capabilities unit, different anti-seismic/vibration
Demand.
