PURPOSE:To detect the flat abrasion of wheels accurately, by improving the arrangement of supporting members, which support rails, and grasping the shearing strain of rails. CONSTITUTION:The flat abrasion of a wheel 4 is detected by detecting the amount of strain of a rail when a rolling stock runs on a railroad track. In this case a pair of rails arranged in parallel are supported by a plurality of supporting pads 2, which are supporting members that support only one rail. A pair of detectors 3a and 3b, which detect the shearing strain of the rail, are attached to the side part of the rail between the supporting pads 2. A section excluding the supporting parts is made to be a measuring section. The supporting pads 2 are arranged in a zigzag pattern over the measuring section (l) so that the section of the supporting pads 2 of one rail is included in the measuring section of the other rail. When the detected output of the measuring sections are added, discontinuous parts are not yielded. In this way, the flat abrasion amount can be detected without the effect of the supporting members. |
