Description
Technical field
The invention belongs to technical field of civil engineering, and in particular to arrive a kind of turbine type viscous damper.
Background technique
Viscous damper is widely used civil construction project etc. is multi-field, and mechanism is to utilize the viscous of damping liquid
Stickiness converts thermal energy consumption for the energy of structure in flow at high speed and dissipates, to realize impact, the protection structure of buffering external load
The purpose of safety.
The viscous damper generallyd use in civil construction project field at present is piston type, and core component is all oil
Cylinder, piston.Its working principle is that being moved back and forth in the cavity by piston, extruding viscous damping liquid passes through tiny on piston
The energy of absorption is converted to thermal energy consumption and dissipated by the gap of oilhole or piston and oil cylinder inner wall.And changing for viscous damper
Into then by control piston at a distance from oil cylinder inner wall or the size of control damping hole and shape improve damping.But
On the whole from piston type viscous damper, piston is one of limited widget that takes up space, and is only considered to work
It is limited obvious to fill in the improved measure of row, since oil cylinder cavity length is limited, causes the effective travel of viscous damper also corresponding
It is restricted, such as needs the damper of big stroke, then only increase, lengthen cavity, viscous damper volume, weight is caused to increase
Greatly；Oil cylinder internal pressure is big at work for piston type viscous damper, and cylinder wall is thicker, and oil cylinder, piston machining accuracy require height,
Cost is typically relatively expensive；Due to the structural property of piston and oil cylinder itself, sealing ring is easy to aging, and piston rod is also easy to wear,
The case where will appear leakage；The installation of piston type viscous damper is complicated, needs using the complicated structure such as spherical hinged-support, oscillating bearing
Part.
Summary of the invention
In view of the above deficiencies, the present invention provides a kind of turbine type viscous damper, easy to use, efficiently solves existing work
The problem that plug viscous damper stroke is short, easy oil leakage, volume is big, cost is high and installation is complicated.
To achieve the above object, the technical solution adopted by the present invention to solve the technical problems is: providing a kind of turbine type
Viscous damper, including pedestal are provided with a cylindrical steel basin on pedestal, and steel basin includes steel basin side wall, steel basin top plate and steel basin
Bottom plate, steel basin is interior to be filled with viscous damping liquid；Rolling bearing, the axis of rolling are provided at steel basin top plate and steel basin bottom plate center
Shaft is provided with by rotating shaft screw bolt between holding, shaft upper end is pierced by steel basin top plate, is provided with several flabellums in shaft；Shaft upper end
It is provided with a steel wire disk, torque spring is socketed between steel wire disk and steel basin top plate, torque spring one end is arranged in steel basin
On top plate, other end setting is wound with several wirerope on steel wire disk, and on steel wire disk.
Further, the inner ring of rolling bearing is higher than outer ring, rolling element and retainer.
Further, sealing rubber ring is provided between shaft, rolling bearing and steel basin top plate.
Further, shaft lower end is not contacted with basin bottom.
Further, flabellum is connect or is bolted by welding, trip with shaft.
Further, steel basin top plate is with steel basin side wall by welding, snapping connection or being threadedly coupled.
Further, steel basin top plate is set between steel basin top plate and steel basin side wall with steel basin side wall by buckle or when being threadedly coupled
It is equipped with sealing rubber ring.
Further, wirerope one end is fixed on steel wire disk, and the other end is connected on works.
Further, pedestal is connect by several bolt of lower base with basis.
Working principle: pedestal bolt of lower base is connect with bridge pier, bridge tower, and wirerope is connected with girder, when bridge, building
Under earthquake, wind shake effect, girder moves structure, the rope traction steel wire disk rotation connecting with girder, thus band
Turn axis and flabellum rotation, rotation of the flabellum in viscous liquid stir viscous damping liquid, make viscous damping liquid from flabellum
It flows through between the gap of steel basin, slows down when flabellum revolving speed is compared with no viscous liquid.Due to the flowing of viscous liquid, by the kinetic energy of flabellum
It is converted to thermal energy consumption to dissipate, realizes the vibration damping purpose to structure.Its working principle is inherently by traditional viscous damper
Reciprocating motion of the pistons is optimized for the rotation of flabellum.
In conclusion the invention has the following advantages that
1, steel basin of the present invention only plays container, and when blade moves in viscous liquid, the flowing of viscous liquid is to steel
Basin is without internal pressure, therefore steel basin need to only be manufactured using metal sheet, and significant without retrofits, the price such as being milled, being dug
Lower than oil cylinder, piston, overall cost is cheap.
2, the present invention is since steel basin is without internal pressure, and under long-time service, viscous damping liquid will not be revealed, and thoroughly solves
During mobile load formula damper is used for a long time, the problem of sealing ring failure causes viscous liquid to leak.
3, installation process of the present invention is simple, only pedestal bolt of lower base need to be connect with bridge pier, bridge tower, wirerope with can transport
Dynamic girder is connected, without the use of the complexity such as spherical hinged-support, expensive connection type；And simple structure, all connections
It is all made of mechanical connection, is easily installed, dismantles, repairs.
4, the length of wirerope can be arranged in turbine type viscous damper provided by the invention according to engineering actual demand, from
And meet the effective damping stroke of the random length of Practical Project demand；Can also steel be connected along any direction according to actual needs
Cord can then apply along any direction and damp；It can also be by changing flabellum quantity, changing the simple and effective ways such as flabellum shape
Change the damping size of viscous damper.
5, of the invention；If steel basin top plate and steel basin side wall using mode is snapped connection, can also be check at any time inside damper
Component working condition facilitates on-call maintenance and replacement internal component.
6, the present invention realizes the automatic drawing back function of wirerope by way of increasing torque spring, guarantees that wirerope begins
It is in tensioning state eventually.
