Title:
TRACK INFORMATION COLLECTION DEVICE AND RAIL AXIAL FORCE MEASUREMENT DEVICE
Document Type and Number:
Japanese Patent JP2017227583
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a track information collection device and rail axial force measurement device capable of continuously collecting pieces of information related to a track required for measurement of rail axial force in a short time.SOLUTION: A rail axial force measurement system 6 sends track information to a track information processor 24 from a track information collection device 8, then the track information processor 24 measures rail axial force based on the track information. The track information collection device 8 automatically and continuously measures and collects pieces of track information such as an eigen frequency of a rail 2A while moving. A track state measurement device 11 measures an eigen frequency of the rail 2A based on a sound generated by the rail 2A, when an excitation device 9 excites the rail 2A. The track information processor 24 executes prescribed processing about the track information collected by the track information collection device 8, and analyzes the track information. A rail axial force measurement device 27 measures rail axial force based on an eigen frequency of the rail 2A measured by the track state measurement device 11.SELECTED DRAWING: Figure 1
