Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only this utility model wherein part
Embodiment rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill
The every other embodiment that personnel are obtained under not making creative work premise, broadly falls into this practicality new
The scope of type protection.
The technical solution of the utility model: a kind of multifunctional intellectual SMA drag-line subtracts, shock isolating pedestal, described
Seat includes upper base plate 1 and has the lower seat board 2 in a chamber, and described seat intracavity has been sequentially stacked buffer board 4, centre
Plate 5, wearing plate 6 and sequentially pass through lower seat board 2, buffer board 4, intermediate plate 5, wearing plate 6 and upper base plate 2
Shearing resistance screw rod 7；
Described bearing also includes some SMA drag-lines 8 and fixed dam 11, and described fixed dam 11 sets
Some drag-line holes, described some SMA drag-lines 8 is had to lay respectively at longitudinal both sides of described bearing, every
SMA drag-line 8 connects with upper and lower fixed dam 11 respectively；
Described bearing also includes being additional to the load-sensing unit 14 outside 2 chambeies of lower seat board, is fixed on SMA drag-line
Magnetic flux transducer 9 in the middle part of in the of 8, data line 15, (FBG) demodulator 16, wireless signal transmitter 17 and
Receive terminal 18.
Further, every described SMA drag-line 8 is made up of SMA silk.
Further, described every SMA drag-line 8 is nested with in the drag-line hole of fixed dam 11, by gear
Plate is fixed bolt 12 and is connected with upper base plate 1, lower seat board 2 by fixed dam 11 respectively.
Further, described SMA drag-line 8 is made semicircular structure, the two ends side of being provided with by an overall rope
Shape fixture 13, inner side is provided with several steel spring packing rings 10.
Embodiment:
As shown in figs. 1 to 6, bearing bottom is the lower seat board 2 of one piece of rectangle, lower seat board 2 towards on one
The central authorities of side hollow out and are formed with a ring-type seat chamber, this intracavity set gradually from bottom to up buffer board 4,
Intermediate plate 5, wearing plate 6.Buffer board 4 is rubber slab, and intermediate plate 5 is steel plate, and wearing plate 6 is polytetrafluoro
Vinyl plate.Wherein, between buffer board 4 and intermediate plate 5, it is provided with sealing ring.Holder top is one piece of square
The upper base plate 1 of shape.
One of technical essential of the technical solution of the utility model is that arranged on left and right sides respectively uses some SMA to draw
Rope 8, according to the shape designed and size coiling and uses square solid at specific part by a SMA drag-line 8
Locking member 13 is reliably bound round fixed, has steel spring packing ring 10 can be finely adjusted the free segment of SMA drag-line 8 at both ends
Length.
The two of the technical essential of the technical solution of the utility model are to make the replacing of SMA drag-line 8 convenient,
Need not dismantle whole bearing.In the present embodiment, for side single SMA drag-line 8, it is by SMA
Silk is constituted.The lower end of SMA drag-line 8 is placed in the drag-line hole of fixed dam 11 as shown, after having placed,
Use baffle plate to fix bolt 12 to be reliably connected with lower seat board 2 by fixed dam 11.Another of SMA drag-line 8
Hold identical with this with the connection of upper base plate 1.So, it is possible to realize the replacing of drag-line part, it is not necessary to will
Whole bearing is detached from the structure and gets off to be replaced SMA drag-line 8.
The three of the technical essential of the technical solution of the utility model can be by the prison to Bearing Seat Force state
Survey, it is possible to achieve the real-time assessment to bridge structure serviceability.At normal operating condition, by being arranged on
Axle power and the resistance of shearing that load-sensing unit 14 outside lower seat board 2 can be born with real time record bearing are believed
Number, it is connected with (FBG) demodulator 16 by data line 15, is then connected to mutually by wireless signal transmitter 17
Networking, is finally obtained the bearing three component result of monitoring in real time, by specialty analysis, has by reception terminal 18
Personnel managed and protected by the bridge of experience can make assessment to the health status of bridge structure, daily to bridge structure
Decision-making accurately is made in maintenance.When an earthquake occurs, by being arranged on the load-sensing unit 14 outside lower seat board 2
The axle power can born with real time record bearing and shearing, add the cable force measurement to every SMA drag-line 8,
Just the faulted condition of bridge structure can be made assessment, the maintenance to shake axle casing structure and bearing is just made
True decision-making.
Under normal condition before earthquake occurs, make upper base plate 1, lower seat board 2 be connect by shearing resistance screw rod 7 to be
Integrally, thus make that the intelligent SMA drag-line of this utility model structure subtracts, shock isolating pedestal shows as hold-down support
Form, i.e. retrained the horizontal displacement between lower seat board 2, upper base plate 1 by shearing resistance screw rod 7.But, local
When shake occurs, when aforesaid horizontal force is more than the shearing strength of shearing resistance screw rod 7,7. shearing resistance screw rod 7 is just cut off,
Relieve upper base plate 1, the constraint of lower seat board 2, make the character of bearing be transformed into many from previous hold-down support
To movable bearing support.Additionally, after shearing resistance screw rod 7 disconnects, bearing is to a lateral movement, when shift value is more than one
When determining design load, both sides SMA drag-line 8 starts to bear pulling force, plays the spacing and effect of power consumption.
As a kind of conversion of the present embodiment, the bearing coordinated with SMA drag-line 8 device can use benzvalene form to prop up
Seat, ball shaped steel bearing, it would however also be possible to employ other types and the bearing of index.
As a kind of conversion of the present embodiment, the bearing coordinated with SMA drag-line 8 device can use described band
There is the hold-down support of shearing resistance screw rod 7, it is also possible to be set directly in sliding support.
As a kind of conversion of the present embodiment, SMA drag-line 8 end can use the steel spring shown in Fig. 5
Packing ring, it would however also be possible to employ organize other similar regulation SMA guy cable lengths that can play such as spring, steel washer more and make
Component.
This utility model is when horizontal displacement exceedes design displacement, and SMA drag-line starts stress, has been possible not only to
Can also dissipate the Seismic input portion of energy to bridge structure to the most spacing effect.At SMA drag-line end
At head fixture, steel spring packing ring is set, before SMA cable pull, plays cushioning effect, and can facilitate
The drift of regulation SMA drag-line section；SMA drag-line part constructs with the separate type of support body with reality
The replaceable function of existing drag-line part.Load-sensing unit outside lower seat board can monitor in real time bearing axle power and
The resistance signal of shearing, the middle part being fixed on SMA drag-line obtains magnetic flux transducer, can record drag-line power
Magnetic signal, is transformed to digital signal by (FBG) demodulator, is connected with the Internet via wireless signal transmitter,
After obtain and monitor result by receiving terminal, it is achieved remotely monitoring and the assessment to bridge structure stress.
The foregoing is only preferred embodiment of the present utility model, not thereby limit protection of the present utility model
Scope, the equivalent done on the basis of this utility model description, improvement, or directly, indirectly use
In the technical field that other is relevant, within being the most in like manner included in protection domain of the present utility model.
