Reduce, at the same the second end 6522 of the first compression bar 652 along abut plate 657 extending direction towards abut plate 657 second end 6572
The second end 6522 of translation, the first compression bar 652 compresses the second elastic component 655；The first end 6531 of second compression bar 653 is pushed away along second
The second end 6512 of the extending direction of movable plate 651 towards the second pushing plate 651 translates, and the first end 6531 of the second compression bar 653 is compressed
Third elastic component 656.
By the elastic restoring force of the first elastic component 641, the second pushing plate 651 application for pushing column 62 is directed away from
The opposition for abutting 657 side of plate applies direction by second end 6522 of second elastic component 655 to the first compression bar 652
The opposition of the second end 6532 of second compression bar 653, so that first end 6521 of first compression bar 652 around the first compression bar 652
Rotation counterclockwise applies the towards the first compression bar 652 by third elastic component 656 to the first end 6531 of the second compression bar 653
The opposition of one end 6521 increases so that the second compression bar 653 is rotated clockwise around the second end 6532 of the second compression bar 653
The tilt angle of first compression bar 652 and the second compression bar 653, so that the first end 6521 of the first compression bar 652 and the second compression bar 653
Second end 6532 by the second pushing plate 651 towards promoting far from abutting 657 side of plate so that rotating bar 63 is around the of rotating bar 63
The rotation counterclockwise of two ends 632, since the length of rotating bar 63 is fixed, rotation axis is changed by vertical state again as heeling condition, and
Block 621 will be abutted to promote towards the left side of the first bumper post 61.
It can be seen that when the first bumper post 61 shakes towards the right side of the first bumper post 61, first Buffer Unit on right side can be to the
The transverse elasticity power in 61 left side of the first bumper post of direction that one bumper post 61 applies.If first Buffer Unit on right side is slow to first
The transverse elasticity power for rushing 61 left side of the first bumper post of direction of the application of column 61 is just slow with the first of 61 pairs of right sides of the first bumper post
The impact force for rushing component application is equal, then the first bumper post 61 can just restore to the intermediate position of the first cushion chamber 51；If right
First Buffer Unit of side is greater than first to the transverse elasticity power in 61 left side of the first bumper post of direction that the first bumper post 61 applies
The impact force that first Buffer Unit on 61 pairs of right sides of bumper post applies, then the first bumper post 61 can squeeze the first buffering group in left side
Part, and first Buffer Unit in left side can apply the transverse elasticity power towards 61 right side of the first bumper post to the first bumper post 61,
Similarly, if the transverse elasticity on 61 right side of the first bumper post of direction that first Buffer Unit in left side applies the first bumper post 61
Power is just equal with the impact force that first Buffer Unit in 61 pairs of left sides of the first bumper post applies, then the first bumper post 61 can just
Restore to the intermediate position of the first cushion chamber 51；If the direction first that first Buffer Unit in left side applies the first bumper post 61
The transverse elasticity power on 61 right side of bumper post is greater than the impact force that first Buffer Unit in 61 pairs of left sides of the first bumper post applies, then right
The transverse elasticity power in 61 left side of the first bumper post of direction that the first Buffer Unit of side again applies the first bumper post 61, with this
Circulation is round-trip, so that the first bumper post 61 left and right in the first cushion chamber 51 moves back and forth, gradually consumes the first bumper post 61 certainly
The seismic force of body, so that the amplitude that the first bumper post 61 moves back and forth in the first cushion chamber 51 can gradually decrease, until first
Bumper post 61 just restores until the intermediate position of the first cushion chamber 51.
As it can be seen that the impact force that can be subject to rubber layer 2 passes through first by the first buffer unit in the first cushion chamber 51
Buffer unit gradually uses up the impact force for totally thereby reducing and acting directly on tunnel ontology 1, improves tunnel ontology 1
Shock resistance.
Embodiment described above, only preferred embodiments of the utility model, be not to limit the utility model practical range,
Therefore all equivalent change or modifications done according to structure, feature and principle described in present utility model application the scope of the patents, it should all wrap
It includes in the utility model patent application range.
