AI Technical Summary
The existing elevator guide shoe structure lacks sufficient space to install four sets of vibration damping mechanisms when encountering two sets of rollers, resulting in a non-compact structure and a large number of parts.
Design a spring-loaded vibration-damping roller guide shoe, which adopts two symmetrical roller groups on the left and right. Each roller group is connected to the guide shoe seat through a bracket and equipped with a vibration-damping mechanism, including an elastic element, a support rod and a drive plate, to push the rollers to fit tightly against the elevator guide rail. The elastic element provides a rebound force to adjust the fit between the rollers and the guide rail.
This design allows both upper and lower rollers on one side to benefit from a single set of vibration damping mechanisms. The structure is compact with few parts, and the elastic force can be adjusted by elastic components to ensure stable contact between the rollers and the guide rail, thus improving the smoothness and safety of elevator operation.
