Title:
DEVICE FOR DETECTING OPENING AMOUNT OF TONGUE RAIL
Document Type and Number:
Japanese Patent JP2015013590
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To highly accurately detect an opening amount in the vicinity of a rail head, even if rail inclination occurs in a tongue rail due to foreign matter interposed between a tongue rail head and a stock rail head, in the approach operation when a tongue rail of a railroad turnout is switched and approaches a stock rail.SOLUTION: A displacement sensor 10 detects a separation amount (first separation amount) of an abdomen of a tongue rail 100 horizontally separated from a position when the tongue rail 100 is brought into abutment with a stock rail 200, in the approach operation when the tongue rail 100 is switched and approaches the stock rail 200. A displacement sensor 20 detects a separation amount (second separation amount) of a detection object 101 attached to the bottom of the tongue rail 100 horizontally separated from the position when the tongue rail 100 is brought into abutment with the stock rail 200 through a horizontally movable rod-like member (not shown) in the approach operation. By using the first separation amount and the second separation amount, an opening amount between the head of the tongue rail 100 and the head of the stock rail 200 is calculated.
