Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Please refer to fig. 1-4, the present embodiment provides a vibration isolator for earthquake resistance of a bridge, which includes a supporting seat 1, a supporting table 3 is disposed at an upper end of the supporting seat 1, the supporting seat 1 is used for supporting the supporting table 3, a damping spring 8 is fixed at a top point of a bottom of the supporting seat 1, one end of the damping spring 8 far away from the supporting seat 1 is fixedly connected to the bottom of the supporting table 3, the damping spring 8 provides an external elastic force, and after the supporting table 3 is extruded, the damping spring 8 can play a role in unloading force, so that the supporting table 3 can reduce vibration amplitude, and further play a role in vibration isolation.

In this embodiment, in order to make the vibration isolator have multi-direction vibration isolation effect, the bottom of supporting seat 1 is fixed with supporting shoe 4, and supporting shoe 4 is the steel material preparation, has very strong hardness and is difficult for taking place to warp, and one side slip of supporting shoe 4 has buffer 7, and buffer 7 has very strong hardness, non-deformable for the steel material preparation equally.

Wherein, the supporting shoe 4 has two and is symmetrical about the vertical center pin of supporting seat 1, supporting shoe 4 becomes right trapezoid shape, and two 4 right trapezoid's of supporting shoe hypotenuse directions are relative, in addition, the bottom of brace table 3 is fixed with backup pad 2, the lower extreme of backup pad 2 is fixed with extrusion ball 5, extrusion ball 5 is located between supporting shoe 4 and buffer block 7, backup pad 2 is used for the support to extrusion ball 5, extrusion ball 5 is the spheroid structure that steel material made, can slide between buffer block 7 and supporting shoe 4.

In addition, buffer block 7 is located between two squeeze balls 5, two squeeze balls 5 are on same horizontal line, when brace table 3 takes place to rock, one of them squeeze ball 5 can lead to the fact the extrusion to buffer block 7 along the hypotenuse direction gliding of supporting shoe 4, then another squeeze ball 5 can play spacing effect when buffer block 7 slides, thereby make buffer block 7 play the effect of vibration isolation to brace table 3, can carry out the vibration isolation to brace table 3 horizontal direction simultaneously.
