The service life of support plate 43.
With reference to Fig. 3 and Fig. 5, uniformly interlocking is fixed with rectangle fastening hoop for upper spherical rotation block 41 and lower peripheral surface moving block 42
46, spherical rotation block 41 and lower peripheral surface moving block 42 are crossed in two opposite sides of fastening hoop 46 respectively, when upper spherical rotation
When relative to lower peripheral surface moving block 42 sliding trend occurs for block 41, fastening hoop 46 holds upper spherical rotation block 41 and lower peripheral surface rotation
Block 42 prevents their Relative sliding,（Referring to Fig.1）The impact force that ontology 3 is passed to bearing 2 simultaneously absorbs, and reaches shock absorbing
Effect.
Referring to Fig.1, lower block 22 is fixedly connected on by built-in fitting in high bridge honest 1, and high bridge honest 1 is internally provided with for inhaling
Receive the shock-damping structure 5 that ontology 3 vibrates（With reference to Fig. 7）.
With reference to Fig. 7, shock-damping structure 5 is made of longitudinal multigroup reinforcing bar 51 and lateral multigroup reinforced steel bar ring 52, longitudinal steel
Muscle 51 passes through high bridge honest 1（Referring to Fig.1）And it is formed by bending waveform,（Referring to Fig.1）The impact force that ontology 3 generates passes through bearing 2
High bridge honest 1 is passed to, is absorbed by wave, while making longitudinal reinforcement 51 that there is the characteristic of Bending Deformation so that is longitudinal
Reinforcing bar 51 is not only with rigidity also with certain toughness.
Make high bridge honest 1 by the toughness of longitudinal reinforcement 51（Referring to Fig.1）Supporting role and cushioning effect more preferably, extend
High bridge honest 1（Referring to Fig.1）Service life.
Reinforced steel bar ring 52 can deform upon in a certain range, and the tensile strength of reinforcing steel bar ring 52 can prevent longitudinal direction
Reinforcing bar 51 deforms upon, and enhances entire high bridge honest 1（Referring to Fig.1）The toughness of internal structure,（Referring to Fig.1）Bring ontology 3 to height
The impact impact force of bridge honest 1 absorbs, and plays good cushioning effect.
With reference to Fig. 4 and Fig. 5, the top of longitudinal reinforcement 51 passes through upper spherical rotation block 41 and lower peripheral surface moving block 42 to protrude shape
The protrusion radian in camber portion 53, curved portion 53 is consistent with support plate 43 so that ontology 3, bearing 2 and high bridge honest 1（Referring to Fig.1）
It is connected as one, increases the stability of bearing 2, while support is played to upper spherical rotation block 41 and lower peripheral surface moving block 42 and is made
With.
The curved portion 53 of longitudinal reinforcement 51 is so that ability of the reinforcing bar 51 with certain Bending Deformation, can absorb spherical surface and turn
Motion block 41 plays the role of damping with respect to the active force of 42 movement tendency of lower peripheral surface moving block.
With reference to Fig. 3 and Fig. 5, it is welded between the longitudinal reinforcement 51 between upper spherical rotation block 41 and lower peripheral surface moving block 42
2 groups of lateral oval garter springs 6, enhance the rigidity and stability of longitudinal reinforcement 51, prevent spherical rotation block 41 and lower peripheral surface
42 relative motion trend of moving block, the serious consequence for avoiding the failure of bearing 2 from bringing.
