Bridge limiting device with multi-stage protection function

The invention provides a bridge limiting device with a multi-stage protection function. The bridge limiting device comprises at least one torsion energy dissipation element and a sliding part, the sliding part comprises a connecting plate and a force transmission guide plate, a connector of the connecting plate is connected with an abutment or a beam body, a sliding groove is formed in the connecting plate, one end of the force transmission guide plate is connected with the sliding groove, and the other end of the force transmission guide plate is rotationally connected with the torsion energy dissipation element. Under the normal temperature rise deformation condition of the beam body, the relative sliding between the connecting plate and the force transfer guide plate adapts to the telescopic deformation caused by the normal temperature rise of the beam body; for general earthquakes and aftershocks which are often accompanied after the earthquakes, the torsion energy dissipation elements are driven to gener
