Title:
GROUND RAIL SWITCH STRUCTURE FOR GAUGE-CHANGEABLE BOGIE
Document Type and Number:
WIPO Patent Application WO/2019/196345
Kind Code:
A1
Abstract:
A ground rail switch structure for a gauge-changeable bogie, comprising a pair of support rails (10) provided in parallel and a pair of first guide rails (20), a pair of gauge-changeable guide rails (30), and a pair of second guide rails (40) provided in sequence along the inner 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-changeable guide rails (30), and a locking section (60) is provided between each of the gauge-changeable guide rails (30) and each of the second guide rails (40); the inner/outer side of the unlocking section (50) and the inner/outer side of the locking section (60) are respectively provided with a pushing and positioning device (70), the pushing and positioning device (70) being used for applying a transverse pushing force to a gauge-changeable wheelset (80) passing through the unlocking section (50) and the locking section (60). A transverse pushing force is applied using the pushing and positioning device (70) to the gauge-changeable wheelset (80), so that both sides of the gauge-changeable wheelset (80) are slightly displaced with respect to the guide rails on which the gauge-changeable wheelset is running, so as to readjust the positional relationships between the components matching each other on the gauge-changeable wheelset (80), facilitating improvement of the positioning precision, ensuring smooth unlocking and locking of the gauge-changeable wheelset.
