Earthquake identification type anti-impact support

The utility model relates to the technical field of bridge supports, and aims to solve the problems that in an existing two-stage anti-seismic spherical steel support, a non-rigidity sliding area is arranged between a first-stage limiting protection structure and a second-stage limiting protection structure, after the first-stage limiting protection structure fails, a second-stage check block needs to bear a large impact load, and the service life of the second-stage check block is influenced. In order to solve the problems that a lower support plate is provided with an inner check block and an outer check block on both sides of the upper direction of a transverse bridge, and the inner check block is positioned between an upper support plate and the outer check block; a shear pin is connected between the inner stop block and the lower support plate; a cavity is formed between the inner check block and the outer check block, and a buffering piece is contained in the cavity. The buffering piece is arranged betw
