Tension compression shock-absorption spherical rotation support

The utility model belongs to the technical field of the bridge support, and discloses a tension compression shock-absorption spherical rotation support, which is mainly characterized by comprising an upper seat board with an upper convex ring, a middle seat board with a lower convex ring and a lower seat board, wherein the top part of the middle seat board is of a convex surface, the bottom part of the upper seat board is of a concave surface, the upper seat board is provided with a T-shaped groove, the middle seat board is provided with a T-shaped groove, a tensile rod passes through the upper and the lower T-shaped grooves, the lower seat board is provided with a lower tensile arm which is matched with the lower convex ring, the bottom part of the middle seat board is provided with an upper energy dissipation board, the top part of the lower seat board is provided with a lower energy dissipation board, the lower seat board is provided with a limiting pin which extends into the lower T-shaped groove, and the limiting pin is provided with a damping rubber ring. The tension compression shock-absorption spherical rotation support is of an integral shape, and can bear the vertical load and transfer the vertical tension. During the rotation process, the tension compression surface of the support is close to contact, the force transferring is uniform, and the support can consume the energy and absorb the shock.
