Multi-stage energy consumption damper based on viscoelastic damping device

The utility model provides a multi-stage energy dissipation damper based on a viscoelastic damping device, and relates to the technical field of damping structures. Comprising an upper connecting plate, a lower connecting plate and a viscoelastic damping device arranged between the upper connecting plate and the lower connecting plate, the viscoelastic damping device comprises a viscoelastic body, and the viscoelastic body is suitable for generating damping force when the middle steel plate and the side steel plates move relatively; a plurality of triangular energy consumption plates are oppositely arranged on the left side and the right side of the viscoelastic damping device, and the bottom face of the upper connecting plate is connected with a plurality of top plate blocks symmetrically distributed on the two sides of the triangular energy consumption plates. And the top plate block is suitable for being in contact with the triangular energy consumption plate when the damping force of the viscoelastic damp
