Cushioning device of screw elevator

The utility model relates to a cushioning device of a screw elevator, which is mainly used on an elevator adopting a screw to lift and comprises a base and at least one damping mechanism arranged on the base. The damping mechanism comprises a base, a movable frame rotationally arranged on the base, a buffer wheel rotationally arranged on the movable frame and an elastic mechanism arranged between the base and the movable frame. When an elevator runs and vibrates, pressure is generated between a buffer wheel and a screw rod, the screw rod vibrates to cause the buffer wheel to move, the buffer wheel slightly moves along with a movable frame, a certain cushioning effect is achieved, vibration between an elevator box body and the screw rod is small, generated noise is low, and the service life of the elevator is prolonged. The technical problems of large vibration and large noise during operation of the screw elevator are solved. 本实用新型涉及一种螺杆电梯的缓震装置，其主要用于采用螺杆升降的电梯上，包括基座、至少一个设于基座上的减震机构，减震机构包括底座、可转动地设于底座上的活动架、可转动地设于
