<p><P>PROBLEM TO BE SOLVED: To provide a railroad track displacement measuring device having a snow melting function, capable of highly reliably and stably measuring track displacement while melting falling snow in a region where snow is accumulated on and around a railroad track. <P>SOLUTION: The railroad track displacement measuring device includes: a plurality of targets 30 for track measurement provided at every prescribed interval in the longitudinal direction of the railroad track; and a track displacement measuring device 10 which is installed near the railroad track and measures the position of the target for the track measurement by projecting measurement light to the target for the track measurement and receiving reflected light; a heating element 51 for melting snow, for generating heat for preventing falling snow from being accumulated at the lower part of the target for track measurement and near the lower part; and a heating element attaching device 50A which is provided with a heating element attaching member 52 where the heating element for melting snow is attached turning a heat radiation surface to a roughly vertical direction, and installs the heating element for melting snow in the railroad track so as to be positioned between the track surface of the railroad track and the target for track measurement. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
