The invention discloses a buffering device for elevator car roof rushing in the technical field of elevator equipment. The buffering device comprises a plurality of buffering assemblies. The buffering assembly comprises a rectangular sliding rail fixed to the wall of the elevator shaft, two movable plates sliding in the vertical direction are connected into the sliding rail in a sliding mode, the two movable plates are arranged side by side and are the first movable plate and the second movable plate in sequence from bottom to top, and a plurality of vertical tension springs are fixed to the lower surface of the first movable plate. The bottom end of each tension spring is fixedly connected with the bottom of the sliding rail, a plurality of first jacking springs are arranged between the first movable plate and the second movable plate, the bottom ends of the first jacking springs are fixedly connected with the first movable plate, the top ends of the first jacking springs are fixedly connected with the second movable plate, and a plurality of vertical second jacking springs are fixedly connected to the upper surface of the second movable plate. The top end of the top spring II is fixedly connected with the top end of the slide rail; a transversely-arranged contact plate is fixedly connected to the first movable plate and used for making contact with the lift car when the lift car rushes to the top. According to the scheme, the impact force generated when the lift car is in contact with the buffering device when rushing to the top is reduced.
