The invention discloses a traction type safety goods elevator. The traction type safety goods elevator comprises a hoistway and a lift car. A collision plate is arranged at the bottom of the lift car, a fixed plate is arranged on the bottom wall of the hoistway, a first arc-shaped buffering piece is arranged at the top of the fixed plate, an impact-resistant plate is arranged above the first arc-shaped buffering piece, a buffering spring is connected between the impact-resistant plate and the fixed plate, a mounting groove is formed in the side wall of the hoistway, and an anti-rebound plate is mounted in the mounting groove through a rotating shaft. The rotating shaft is sleeved with a torsional spring, the torsional spring is used for driving the anti-rebound plate to keep a vertical state, a rotating arm is arranged on the side portion of the anti-rebound plate, a transverse sliding groove is formed in the groove wall of the mounting groove, a movable check block is connected into the transverse sliding groove, a reset spring is connected to the inner end of the movable check block, and a driven inclined face is arranged at the outer end of the movable check block; and a driving inclined surface corresponding to the driven inclined surface is arranged at the bottom end of the anti-rebound plate. According to the traction type safety goods elevator, the good buffering effect on accidental falling of the goods elevator can be achieved, secondary falling caused by rebounding of the goods elevator can be prevented, and the better protection effect is achieved.
