The invention discloses a polyurethane vibration attenuation structure of a heavy freight elevator car frame diversion sheave. The polyurethane vibration attenuation structure of the heavy freight elevator car frame diversion sheave comprises a car frame for lifting an elevator car, a transverse shaft is fastened on an upper beam of the car frame through screw threads, a rotary diversion sheave is mounted on the shaft, and polyurethane vibration attenuation rubber and clamping plates are arranged sequentially between the upper beam and the shaft as pads. According to the polyurethane vibration attenuation structure of the heavy freight elevator car frame diversion sheave, the polyurethane vibration attenuation rubber and the clamping plates are arranged sequentially between the upper beam of the car frame and the shaft of the diversion sheave as pads so that flexible vibration attenuation can be achieved, vibration of steel wire ropes to car frame wall plates can be reduced, noises are lowered, and the advantages of good resilience, excellent abrasion resistance, long service life and high pressure resistance of the polyurethane vibration attenuation rubber are applied.
