|発明の名称||PANTOGRAPH LIFT MEASURING DEVICE|
PROBLEM TO BE SOLVED: To provide a pantograph lift measuring device capable of measuring accurately a pantograph lift simultaneously with an aerodynamic sound without being influenced by air current.
SOLUTION: A damper device 14 is dismounted, and a connection part 17 is fixed to a lever part 6d of a main shaft 6, and a connection part 18 is fixed to a fixing part 13e of a frame 13, and a pantograph lift detection part 16 and the connection parts 17, 18 are mounted on a pantograph 1. When adjusting an interlocking amount between the connection parts 17, 18 and an interval adjusting part 18c, the attitude of the pantograph 1 is changed and the height of a collector head 3 is adjusted. Since the pantograph lift detection part 16 and the connection parts 17, 18 are covered with a windshield part 12, air current does not exert an influence thereon, and application of air force can be prevented, and generation of an aerodynamic sound can be prevented. Resultantly, since the pantograph lift detection part 16 is not influenced by the air current, the pantograph lift and a noise can be measured simultaneously accurately.
