Abstract
This invention relates to the field of auxiliary transportation equipment for stairwells, and discloses an anti-derailment and guiding mechanism for a geared handrail stairwell riding chair. The mechanism includes a chair body; two sets of anti-derailment guiding devices symmetrically distributed on the chair body; an anti-derailment retaining ring fixedly connected to the chair body and located at the center line of the two sets of anti-derailment guiding devices; and a power-driven walking mechanism mounted on the chair body. In this invention, by setting two sets of symmetrically distributed anti-derailment guiding devices and an anti-derailment retaining ring located at the center line, a multi-layered anti-derailment protection structure is formed. The anti-derailment guiding devices precisely engage with the track, effectively limiting the horizontal deviation of the chair body. The anti-derailment retaining ring further wraps and limits the track, preventing the chair body from shifting along the geared track axis. This dual protection significantly reduces the risk of derailment and improves operational safety.
