AI Technical Summary

Technical Problem

In existing elevator car anti-sway mechanisms, the rubber pads are not stiff enough, which leads to plastic deformation under excessive load, reduced guiding accuracy, greater friction on one side of the car body, lateral torque, severe swaying, or even resonance.

Method used

It adopts a multi-stage buffer structure, including a support mechanism and a fixing mechanism. It uses a multi-stage buffer system composed of damping rods and springs to consume vibration energy through the elastic potential energy of the material, reduce the swaying amplitude, and ensure that the damping characteristics on both sides are consistent through symmetrical design to prevent excessive friction on one side.

Benefits of technology

It effectively reduces the swaying amplitude of the elevator car, prevents a decrease in guiding accuracy and resonance, and ensures the stability and safety of elevator operation.
