摘要： PURPOSE:To easily measure the remaining diameter of a trolley line by providing plural optical fibers for light reception to a light receiver and making a light beam from an optical fiber for light projection incident on one optical fiber for light reception at a position corresponding to the remaining diameter of the trolley line and detecting the light beam. CONSTITUTION:The horizontal side 3b of an L-shaped support is hooked on the overhead trolley line 1 and a rope 7 is drawn by the hand; and then a pulley 6 and a pinion 5 rotate and a rack 5b which engages the pinion elevates a mover 4. Here, the plane of a contact part 4b contacts the slide surface of the trolley wire 1 to grip the trolley line 1 with the horizontal side 3b. In this state, the light beam projected horizontally by the optical fiber 4d for light projection is received by one of the optical fibers 8a for light reception and then processor detects its array position to obtain the remaining diameter of the trolley line 1 immediately.

摘要： PURPOSE:To optically measure the height of a trolley wire in a non-contact state by detecting a position corresponding to the height of the trolley wire from an image outputted from a light receiving optical system. CONSTITUTION:A light emitting optical system 7 and light receiving optical system 8 are symmetrically arranged with respect to a trolley wire wear measuring instrument 6 provided on a car body 3 on both sides of the instrument 6. The system 7 is constituted of a light source 7a, slit plate 7b, and projection lens 7c of which the plate 7b is set so that the direction of its slit can become perpendicular to the locus in the horizontal direction and the lens 7c is set so that the slit light projected in an upward oblique direction through the lens 7c can cover the deflected extent of a trolley wire 1. The slit light is reflected from the point (p), (q), or (r) of a trolley wire 1, 1', or 1'' after irradiating the point (p), (q), or (r). The reflected light is condensed through a condenser lens 8a and further converged in a section perpendicular to the locus direction by means of a cylindrical lens 8b. The converged reflected light forms the image of the point (p), (q), or (r) in a CCD sensor 8. The address signal of the picture element of the sensor 9 is inputted to a signal processing section 10 and the height of the trolley wire is found.

摘要： PURPOSE:To detect the position of trolley wire supporting metal fittings even under any environmental conditions day and night by fitting an optical system in the direction to irradiate the trolley wire supporting metal fittings of an electric pole without necessitating to adjust a setting-up angle of a projector. CONSTITUTION:Laser beams emitted from a laser diode 1 are made parallel beams through a lens 3 and enter a prism 4 and the optical path is bent orthogonally and advances orthogonally to the advancing direction of a truck for detection/measurement in the direction of the trolley wire supporting metal fittings fitted to the electric pole upward the truck. Next, the laser beams are reflected and diffused by the supporting metal fittings and return orthogonally to the advancing direction of the truck and are photodetected, reflected and converged by a concave mirror 5 and the optical path is again bent orthogonally by the prism 4 and made incident on a photodetector 7 passing through a filter 6. Then, the laser beams are converted photoelectrically here and made an electrical signal and enter a photodetecting level signal control circuit 8 and the necessary processing is performed there and a sure and accurate electric pole position detection signal is selected and outputted.
