GROUND GAUGE CHANGING APPARATUS FOR GAUGE-CHANGEABLE WHEELSET

A ground gauge-changing facility for a gauge-changing wheelset comprises a pair of support rails (10) provided in parallel, and a pair of first guide rails (20), a pair of gauge-changing guide rails (30), and a pair of second guide rails (40) provided in sequence along interior sides of the pair of support rails (10); an unlocking section (50) is provided between each of the first guide rails (20) and each of the gauge-changing guide rails (30), and an unlocking emergency braking section (51) is provided between each of the unlocking sections (50) and each of the gauge-changing guide rails (30); a locking section (60) is provided between each of the gauge-changing guide rails (30) and each of the second guide rails (40), and a locking emergency braking section (61) is provided between each of the locking sections (60) and each of the second guide rails (40). The ground gauge-changing facility can eliminate the risk on safety in the existing ground gauge-changing facilities and avoid potential accident loss.
