摘要： PROBLEM TO BE SOLVED: To provide a resistance measuring instrument for an electric wire connecting part where an electric wire can be easily attached and resistance of the electric wire connecting part can be easily measured with high accuracy in a hot line. SOLUTION: The measuring instrument 1 comprises an attachment part 2 at an upper part, an insulation rail bar 3 at a lower part, and a lift 4 that goes up and down along the insulation rail bar 3. On the attachment part 2, clamp electrodes 6 are placed at both ends of a concatenation bar 5, and a clamp meter 7 is placed at a center. On the clamp electrodes 6 opening and closing mechanisms 10 that hold an electric wire W and electric wire polishing mechanisms 11 are placed to be operated by a controlling part in the lift 4. The clamp meter 7 measures a current by holding an electric wire connecting part W1. The insulation bar 3 has a rack rail 3b in a longitudinal direction. The lift 4 has the controlling part, a voltage measuring instrument 17, and a driving mechanism. The insulation rail bar 3 is placed and the attachment part 2 is hung to be held to the electric wire connecting part W1. The lift 4 is attached to the insulation rail bar 3 to be lifted up and electrically connected to be measured, and then the resistance is calculated from the measured current voltage.

摘要： PROBLEM TO BE SOLVED: To eliminate position where inspection is impossible just before or after the obstacle by running over an obstacle such as a wire connection sleeve. SOLUTION: In this wire inspection device 1, a running distance from a base point is measured by a rotary encoder 30, while it runs on a wire W by means of rollers 12, 13 for detecting a damaged condition of the wire W by damage detectors 21, 22 provided with eddy current sensors. For a sleeve S as an obstacle on the wire W, its back end is detected by a sensor 31, and its forward end is detected by a sensor 32. First, the damage detector 21 is placed on an inspection position, with the damage detector 22 placed on a retraction position, so the wire W is inspected by the damage detector 21 only while it runs. As the back end of the sleeve S is detected by the sensor 31, the damage detector 21 is retracted upward at a position close to the back end. After passing the sleeve S to detect the forward end by the sensor 32, the front and the back damage detectors 21, 22 are both restored, and inspection is restarted. The damage detector 22 starts inspection at a position close to the forward end of the sleeve S. After running for a specified distance, the damage detector 22 is retracted upward, and inspection is performed by the damage detector 21 only.

摘要： PURPOSE:To automatically record the position and state of the breakage on an electric wire by installing a detecting means for detecting the breakage state of the electric wire, measurement means for measuring the traveling distance from a basic point and a controller which treats the data supplied from the detecting mean and the measurement means and memories the result in an outside memory device. CONSTITUTION:A device body 1 travels, vertically nipping an electric wire W by traveling rollers 12 and 13 and a pressing roller and rolling the traveling rollers 12 and 13 on the electric wire W. A breakage detector 21 equipped with an over-current sensor shifts directly over along the electric wire W and detects the wearing-out of the electric wire W. Further, accompanied with the traveling of the device, a rotary encoder 31 rolls on the electric wire W, and measures the traveling distance from a basic point. The data of the breakage detector 21 and the rotary encoder 31 is treated by a controller, and memorized in an outside memory device such as an IC memory card. An obstacle on the electric wire during the traveling, e.g. straight line shaped sleeve and branched sleeve is detected by optical sensors 32a and 32b.

摘要： PROBLEM TO BE SOLVED: To provide an electric traction inspection apparatus rapidly performing inspection by stably self-traveling on an overhead line while avoiding obstacles without hindrance. SOLUTION: The inspection apparatus 1 inspects two overhead lines M using an eddy current sensor 18 while traveling on the overhead lines M by means of four travel rollers 3 driven by motors 4 and 5. Retaining roller 6 are provided for rolling on the lower surfaces of the overhead lines M during travel. Arms 7 for supporting the retaining rollers 6 are freely rotatably supported against a frame 2 and rotated by an arm driving motor 10 between a retaining position and a retracted position. The arms 7 position the rollers 6 below the overhead lines M at the retaining position and position the rollers besides the frame 2 at the retracted position. Sensors 14, 15 and 16 are used to detect any obstacles on a path of travel, with the arms 7 rotated outwards in accordance with the sensor signals to avoid the obstacles. As the arms 7 advance, the front and rear of the arms are individually brought into retracting movement, and either the front or rear retaining roller 6 holds the overhead line M from below at any times.
