Abstract
PURPOSE:To make it possible to automatically detect the displacement in a height direction and the abrasion amount of a third rail, by providing a contact portion of the device for contact with a base portion of the third rail in a longitudinal slide arm and supporting a contact portion of the device for contact with an upper surface of the third rail supplied with power by the longitudinal slide arm in a manner to be movable up and down. CONSTITUTION:A longitudinal slide arm 7 is supported by a vertical portion 6a in a manner to be movable up and down, and provided with a horizontal arm portion 7a extending towards a third rail 1. At a front end of the horizontal arm portion 7a is supported a roller 28 for measuring the displacement of the rail 1 in a height direction, which is pressed into contact with a non-abrasive upper surface 1c of a base portion 1b of the rail 1. Moreover, an optical rotary encoder 30 is placed at the end of the arm portion 7a, so that the running position (moving distance) of the rail 1 is detected by the encoder 30. A metallic detecting member 31 is provided at the upper end portion of the arm 7 for measuring the displacement of the rail 1 in a height direction, and a detecting coil 32 is so provided at the under surface of a cross slide arm 6 as to confront to the detecting arm 31 with some distance therebetween, thereby forming an electromagnetic sensor 33 for measuring the displacement of the rail in a height direction. Specifically, the displacement of the rail 1 in a height direction with respect to the upper surface of a track rail 2 can be detected by measuring the change of the distance H3 between the detecting member 31 and the detecting coil 32.
