(LASER TYPE) MOBILE TRACK THREE-POINT MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a (laser type) mobile track three-point measuring device that enables one operator to not only efficiently perform track inspection but also perform operations without the need for skills.SOLUTION: The amount of longitudinal level irregularity caused by height-direction displacement of a rail 21 and the amount of alignment irregularity caused by displacement in a rail width direction are measured by using an emitter 861 for laser light 88 applied toward a 10 m measurement chord 7 by a measuring device 8, a photo detector 862 for the laser light 88 reflected by being applied toward the 10 m measurement chord 7, and measured values of the irradiation light and reflected light of the laser light 88.
