Description
Technical field
The utility model is related to a kind of flexible suspension, especially with regard to a kind of nuclear power station ventilating system airduct antidetonation elastic lifting
Frame, belongs to nuclear power station ventilating system technical field.
Background technology
Nuclear power station ventilating system Air duct hanging bracket is its important supporting construction, and existing nuclear power station considers antidetonation and fireproof
It is required that, rigid hanger is typically all used, therefore blower fan unit vibration is delivered to building structure by airduct and rigid hanger, so that
Formation solid-borne sound transmission, an important noise source as room noise in building, the noise is based on middle low frequency, hence it is evident that increase
Indoor subjective annoyance.
Utility model content
In view of the above-mentioned problems, the purpose of this utility model is to provide a kind of flexible suspension acted on vibration and noise reducing, can
With the solid sound for reducing or blocking airduct to be delivered in building structure, while can ensure that the structural strength of suspension bracket meets antidetonation and wanted
Ask.
To achieve the above object, the utility model takes following technical scheme：
A kind of antidetonation flexible suspension of nuclear power station ventilating system airduct, the suspension bracket include fixed plate, suspension rod, steel spring every
Shake device and elastic pipe collar；The steel spring vibration isolator is arranged on suspension rod, and the elastic pipe collar is arranged in fixed plate；It is described to hang
One end of bar is fixed in fixed plate, and the other end is fixed on wall.
Further, the antidetonation flexible suspension of nuclear power station ventilating system airduct as described above, the airduct is fixed on described
On elastic pipe collar；The position that the elastic pipe collar is contacted with airduct uses the metal damping isolation felt parcel of A grades of fire prevention.
Further, the antidetonation flexible suspension of nuclear power station ventilating system airduct as described above, using bolt arrangement by elasticity
Pipe collar is fixed in fixed plate.
Further, the antidetonation flexible suspension of nuclear power station ventilating system airduct as described above, the steel spring vibration isolator
Two ends are arranged on suspension rod by bolt.
Further, in the antidetonation flexible suspension of nuclear power station ventilating system airduct as described above, the steel spring vibration isolator
Portion has steel spring, and the steel spring is bolted on the fixed pedestal inside steel spring vibration isolator.
The utility model is rational in infrastructure, vibration insulation and noise reduction effect significantly, vibration isolation bandwidth, vibration isolation efficiency more than 90%,
While realizing vibration insulation and noise reduction, the shock strength and rigidity requirement of 1 grade of equipment of nuclear power antidetonation are met, can be widely used as various logical
The supporting construction of wind system airduct.
Brief description of the drawings
Fig. 1 is the structural representation of the antidetonation flexible suspension of the utility model nuclear power station ventilating system airduct.
Fig. 2 is the structural representation of steel spring vibration isolator.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
As shown in figure 1, the antidetonation flexible suspension of nuclear power station ventilating system airduct provided by the utility model, including fixation
Plate 1, suspension rod 2, steel spring vibration isolator 3 and elastic pipe collar 4；The steel spring vibration isolator 3 is arranged on suspension rod 2, the elastic tube
Hoop 4 is arranged in fixed plate 1；One end of the suspension rod 2 is fixed in fixed plate 1, and the other end is fixed in top wall 5.Wind
Pipe 6 is fixed on the elastic pipe collar 4.
As shown in Fig. 2 the two ends of steel spring vibration isolator 3 are arranged on suspension rod 2 by bolt, inside steel spring vibration isolator 3
With steel spring 7, the steel spring 7 is bolted on the fixed pedestal 8 inside steel spring vibration isolator 3.By in suspension rod 2
Upper setting steel spring vibration isolator 3, a less scope is limited in by the solid sound being delivered to by suspension rod 2 in building structure
It is interior, so as to effectively reduce the radiated noise of building structure, reduce the influence to indoor sound environment.
The steel spring vibration isolator 3 when carries scope according to airduct appearance and size and weight by vibration isolator rigidity, damping
Matched design realize vibration isolation and anti-seismic performance, wherein vibration isolator rigidity is 32~70N/mm, damping ratio is 0.06~0.07,
Carrying scope is 80~140kg.
By setting elastic pipe collar 4 on suspension bracket, and use the metal damping isolation felt parcel airduct 6 and bullet of A grades of fire prevention
Property the position that contacts of pipe collar 4, and elastic pipe collar 4 is fixed in suspension bracket fixed plate 1 using bolt arrangement.Moved in limitation airduct 6
While dynamic, it is possible to decrease airduct 6 is delivered to the solid sound of suspension rod 2, especially medium-high frequency solid sound.
Obviously, those skilled in the art can carry out various changes and modification without departing from this practicality to the utility model
New spirit and scope.So, if belonging to the utility model claim to these modifications and variations of the present utility model
And its within the scope of equivalent technology, then the utility model is also intended to comprising including these changes and modification.
