Title:
DISTANCE METERING DEVICE
Document Type and Number:
Japanese Patent JP2016014601
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a distance metering device that can easily meter the shortest distance between a prescribed portion of one rail track and an object or prescribed portion of the object.SOLUTION: A distance metering device comprises: a dolly that includes a first part 11 in which a wheel 13 to be loaded on one rail of one rail track is attached to each of both ends in a long side direction, and a second part 12 in which the wheel 13 to be loaded on other rail of one rail track is attached to one end in the long side direction, and has other end in the long-side direction connecting to the first part 11; and a computation device 60 that calculates a distance on the basis of a distance L metered by a laser distance meter 30 and an angle θ of laser emission detected by emission angle detection means (inclination sensor 40) and from the laser distance meter 30. When viewing from above, a laser emission direction of the laser distance meter 30 is perpendicular to the long side direction of the first part 11, and in the dolly 10, pressure means (wheel movement mechanism 14) is provided that is for pressing two wheels 13 attached to the first part 11 against one rail of one rail track.
