The application provides a bridge pier anti-collision device and an anti-collision bridge, and relates to the technical field of bridge anti-collision engineering. The bridge pier anti-collision device comprises an anti-collision framework and a plate group. The plate group is installed on the outer side of the anti-collision framework. The plate group has an inner fixed surface and an outer deflecting surface. The inner fixed surface is in abutment with the outer side of the anti-collision framework. A plurality of rolling rods are arranged between the inner fixed surface and the outer deflecting surface. The rolling rods extend along a direction parallel to the bottom of the anti-collision framework and point to the top. The plurality of rolling rods are used to guide the outer deflecting surface to dislocate relative to the inner fixed surface when the outer deflecting surface is impacted. The bridge pier anti-collision device provided by the application breaks away from the traditional mode of absorbing energy through deformation to buffer the impact force of a ship. Instead, the ship head is deflected to make most of the kinetic energy remain in the impacted ship, effectively reducing the transmission of the impact force to the bridge pier, and achieving a better anti-collision effect.
