MEASURING FRAME FOR TRACK INSPECTION CAR

摘要

PROBLEM TO BE SOLVED: To maintain a distance between a track inspection sensor and a track within a fixed range by damping flexural vibration generated in an equalizing beam and a measuring beam, in an early stage. SOLUTION: The equalizing beam 2 and the measuring beam 3 are connected through an oblique link 11 having a vibration damping mechanism 12. The measuring beam 2 is provided with a vibration damping device 15 with a weight 14 added onto a vibration damping mechanism 13. A mounting part of the equalizing beam 2 for an axle box is provided with a reinforcing member 9 for preventing flexure. A vibration damping device 8 is provided between the equalizing beam 2 and a side beam 7.
