PLUMB BOB DROP TESTER
PROBLEM TO BE SOLVED: To provide a plumb bob drop tester that can precisely evaluate the state of an evaluation target object such as a ballast track, by including speed increasing means for increasing the drop speed of a plumb bob, without involving increase in the size of a device.SOLUTION: The plumb bob drop tester evaluates the state of an evaluation target object 17 by dropping a plumb bob 6 onto an evaluation target object, with a mounting plate 1 mounted thereon, along a column support 5, vertically fixed on the mounting plate 1 and by measuring a load value applied on the mounting plate 1 and a displacement of the evaluation target object associated with the drop of the plumb bob 6. The plumb bob drop tester includes speed increasing means 9 for increasing the drop speed of the plumb bob 6.SELECTED DRAWING: Figure 1
【課題】重錘の落下速度を速める増速手段を設けることによって、装置を大型化することなく、バラスト軌道等の評価対象物の状態を的確に評価することができる重錘落下試験装置を提供する。【解決手段】評価対象物上に載荷板１を介して重錘６を、載荷板１上に垂直に固定された支柱５に沿って落下させ、このときの載荷板１に加わる荷重値と、重錘６の落下に伴う評価対象物の変位とを計測して、評価対象物１７の状態を評価する重錘落下試験装置において、重錘６の落下速度を速める増速手段９が設けられている。【選択図】図１
