The lateral thrust is applied by the pushing and positioning device (70) to the gauge-changing wheelset (80), so that both sides of the gauge-changing wheelset (80) are slightly displaced relative to the guide rails on which the gauge-changing wheelset runs, so as to readjust the positional relation between the components matched with each other on the gauge-changing wheelset (80), and facilitate improvement of the positioning precision, and ensure smooth unlocking and locking of the gauge-changing wheelset.",
