Specific embodiment
The present invention is further elaborated below by drawings and examples.
As shown in attached drawing 1-5: a kind of adjustable apparatus suitable for truss-string-structure energy-dissipating and shock-absorbing, including for connecting
Multiple regulating devices of truss string structure and earth's surface, regulating device include the elastic body of rod 3, the elastic body of rod 3 include upper connector 31, under
Connecting tube 39, spring 35, threaded rod 32, threaded rod 32 are respectively embedded into upper connector 31 and lower connector 39, spring 35 it is upper
Lower both ends are connect with respective threaded bar 32 respectively, and upper connector 31 can be placed in lower connector 39.Threaded rod 32 is respectively with vertical
It is embedded in upper connector 31 and 39 direction of lower connector, the tube wall connection position of threaded rod 32 and upper connector 31 and lower connector 39
Gasket 34 has been installed, and has been fastened by nut 33.
The connection of elastic 3 corresponding component of the body of rod is as follows:
31 sets of the lesser hollow upper connector of diameter in the hollow lower connector 39 being relatively large in diameter, with guarantee two it is upper,
Lower connector 39 can relatively move, meanwhile, 38 sets of the rubber ring outsides in the lesser upper connector 31 of diameter, in reduction,
Lower connector 39 generates the friction generated when relative movement.Threaded rod 32 is inserted into upper connector 31 respectively and lower connector 39 is opened
Circular port in, and gasket 34 is inserted in threaded rod, is tightened with nut 33, prevent the screwing force of nut 33 from crossing on macrolesion,
Lower connector 39.
With crotch, the crotch at both ends hooks the threaded rod positioned at its two sides respectively at 35 both ends of spring in this programme
32, annular aluminium flake 36 is welded on the outside of upper connector 31.Rubber film 37 is fixedly connected with annular aluminium flake 36.Lateral wall is equipped with
Rubber film 37, the tube wall of upper connector 31 are arranged with annular aluminium flake 36, and the upper end of rubber film 37 is supported in annular aluminium flake 36.
The position that rubber film 37 joins both ends upper connector 31, lower connector 39 carries out closed package, prevents rainwater and sundries
Deng entering upper connector 31, inside 39 body of lower connector.
It should be noted that be preferably disposed at truss string structure both ends curvature biggish curved for the elastic body of rod 3 in this programme
In arc frame, better effect is had for the compression load-bearing of entire truss string structure and raising wind resistance in this way.
The elastic body of rod 3 is equipped with tangent displacement sensor, the specific outer wall for being set to upper connector 31 and lower connector 39
Between.Wherein, tangent displacement sensor can be bought in the market, by tangent displacement sensor and the fixed company of the elastic body of rod 3
It is connected together, the opposite position of upper connector 31, lower connector 39 in the elastic body of rod 3 is measured by tangent displacement sensor
It moves, and then calculates the suffered elastic force inside the elastic body of rod 3.
Regulating device further includes lift component, and the bottom of the elastic body of rod 3 is connected with the top of lift component.
Lift component of the invention is hydraulic cylinder 6.The upper end of upper connector 31 is connected with otic placode 1, liquid by hollow pipe 2
The lower end of compressing cylinder 6 is connected with otic placode 1 by hollow pipe 2.
Wherein be fixed with board-like lifting lug 5 in the lower weld of spring bar body 3, the upper and lower ends of hydraulic cylinder 6 respectively with
Board-like 5 pin shaft of lifting lug connection (lower end is connect by board-like lifting lug 5 with trolley), hollow pipe 2 is weldingly fixed under board-like lifting lug 5
End, otic placode 1 are weldingly fixed on the lower end of hollow pipe 2.
The upper end of the elastic body of rod 3 is connected with otic placode 1, and corresponding otic placode 1 is connected with truss string structure, and the bottom of trolley 7 is set
There is pulley, can be moved above in the track on ground (present apparatus during the installation process, is needed in ground matching track use), it is sliding
Wheel with track combining and (by way of pulley snaps into sliding rail, playing certain limit), between realization device bottom and earth's surface
Connect fixation.
As shown in Fig. 7, for the pulley in moving trolley by combining with track, sliding rail should be in vertical direction to trolley
With certain position-limiting action, realization device bottom is fixed indirectly with earth's surface.
When in use, since truss string structure different location is different from the difference in height on ground, the moveable trolley 7 of lower end exists
When the track on ground is moved above to corresponding position, the link position of elastic 3 relative trolley 7 of the body of rod and truss string structure can be changed
Become, causes the length of whole device that can be varied, it accordingly can not to the anti seismic efficiency for improving entire truss string structure yet
Together.Therefore, the present invention achievees the purpose that the present invention flexibly stretches by hydraulic cylinder 6.
With reference to Fig. 6, for truss string structure when by violent high wind, (Open Side Down is for curve in contact truss string structure for high wind
Truss string structure, opening upwards are the drawstring of last quarter rope) when upward pulling force can be generated to it or downward pressure (is specifically seen
Wind direction), cause truss string structure by certain deformational stress, load transfer at this time to the biggish curved arc frame of both ends curvature and middle part are bent
On the lesser curved arc frame interface point of rate, truss-string-structure is easy to cause overall collapse occur.Therefore, this programme is in truss string structure
It is upper that the regulating device being connected with ground is set, and the performance of its elastic body of rod bidirectional stress is made full use of, increase to a certain extent
The lateral stability of strong truss string structure, especially under the influence of the catastrophe factor such as earthquake, typhoon, truss string structure has bigger compression
Load-bearing and resistance wind-loading resistance.
Foundation embodiment described above is enlightenment, and through the above description, relevant staff completely can be not
In the range of deviateing this invention thought, various changes and amendments are carried out.This item uses novel technical scope not
The content being confined on specification, it is necessary to the range of its protection is determined according to scope of the claims.
