Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
UHV shock insulation anti-drop device as shown in Fig. 1 ~ 2, comprise damping support 1, damping support 1 is interval with the first steel plate 2 and the first thin rubber layer 3 of horizontal arrangement from top to bottom, the center of damping support 1 is provided with center hole 4, be provided with lead for retractable pencil 5 in center hole 4, it is characterized in that: also be provided with up and down parallel upper junction plate 7 and lower connecting plate 8, the above and below of damping support 1 is connected with the center of upper junction plate 7, lower connecting plate 8 respectively; The mid point of upper junction plate 7 four edges is provided with anti-fall pad 6; Anti-fall pad 6 by the second thin rubber layer 61, the second steel plate 62, rubber layer 63 with on being connected steel plate 64 under connect successively and be sulfided into integrative-structure by High Temperature High Pressure.
As shown in Figure 2, damping support 1 also is provided with up and down parallel upper envelope steel plate 10, lower seal steel plate 11 and rubber wall 12, the rubber wall 12 of upper envelope steel plate 10, lower seal steel plate 11 and surrounding is enclosed the formation housing structure, is interval with four layer of first steel plate 2 and five layer of first thin rubber layer 3 of horizontal arrangement in housing structure from top to bottom.
As shown in Fig. 3 ~ 4, the second thin rubber layer 61 is 1:10 with the Thickness Ratio of rubber layer 63; Envelope steel plate 64 is provided with connecting bolt hole 9.
The beneficial effects of the utility model are as follows:
One, this device horizontal rigidity are little, and converter power transformer is had good damping effect.The utility model proposes a kind of novel UHV shock insulation anti-drop device first, the rubber earthquake isolation support individual layer rubber layer thickness that it adopts is more than the twice of rubber earthquake isolation support for building, total height remains unchanged, unidimensional novel shock-absorbing and energy-dissipating device is that rubber earthquake isolation support for building is below 0.5 times, can effectively reduce the horizontal rigidity of damping support, significantly improve the earthquake isolation effect to UHV, and stability is substantially constant.
Two, this device has anti-drop, can guarantee the vertical stability of shock insulation UHV under super earthquake intensity geological process, and after shock-absorbing and energy-dissipating device lost efficacy, still has certain damping effect.The UHV shock-proof device of using at present is when vertical unstability, and converter power transformer will fall from damping support, cause the destruction of converter power transformer.
Working principle of the present utility model and process are as follows: each UHV shock insulation anti-drop device presses damping support and four anti-fall pads to form by a low rigidity, bottom surface, by upper lower connecting plate and converter power transformer ground be connected the raft plate top surface and be connected.Anti-fall pad is comprised of thin layer rubber (G3 rubber), one deck laminated steel plate and envelope steel plate.After damping support in UHV shock insulation anti-drop device lost efficacy, the top converter power transformer is with the Contact Thin rubber layer, " soft " of realizing converter power transformer falls, converter power transformer gravity evenly is delivered to thick rubber layer by steel plate, thick rubber layer vertical deformation, rigidity is increasing, the restriction vertical deformation, anti-fall pad can produce shear deformation in the horizontal direction simultaneously, and substantially horizontal plays cushioning effect.When therefore anti-fall pad has anti-drop, have certain damping effect, realize that UHV shock insulation anti-drop device has the function of Fail safe.
Damping support of the present utility model has bottom surface pressure, end horizontal rigidity.It adopts the individual layer rubber layer thickness is more than the twice of rubber earthquake isolation support for building, total height remains unchanged, unidimensional damping support is that rubber earthquake isolation support for building is below 0.5 times, therefore can effectively reduce the horizontal rigidity of damping support, thereby improve the earthquake isolation effect to UHV, and stability is substantially constant.
