The invention discloses a rope wheel dynamic damping device which comprises a rope wheel assembly and a damping assembly. The rope wheel assembly is fixed to the lower portion of a bearing cross beam of an elevator car or a counterweight, and the vibration reduction assembly is fixed to the upper portion of the bearing cross beam of the elevator car or the counterweight. The rope wheel assembly comprises a rope wheel, a wheel shaft, a beam and a U-shaped fixing piece. The rope wheel is rotatably fixed on the beam through a U-shaped fixing piece, the wheel shaft and the beam are relatively fixed, and the beam is fixedly connected with the bearing cross beam; the damping assembly comprises a plurality of damping tensioning wheels, a base, a connecting arm and a dynamic damper. The dynamic shock absorber is provided with a connecting plate, a connecting arm, a dynamic shock absorption arm and a mass block; the damping tensioning wheels arranged on the upper portion are rotatably fixed to the two ends of the connecting arm. The dynamic vibration reduction arm is fixed on the connecting plate and vertically extends out of the connecting plate along the horizontal direction, and the mass block is fixed at the extending end part of the dynamic vibration reduction arm; after the rope winds around the rope wheel, the rope is located on the inner side of the vibration reduction tensioning wheel and makes contact with the vibration reduction tensioning wheel.
