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.

摘要： PURPOSE:To improve the extent of operatability, by constituting the above-captioned device, for keeping electric potential at a working spot and that at an operator himself equally, to be connectedly usable without setting it each time in case of changing the working position, when hot-line work on an electric-car line is carried out. CONSTITUTION:A movable plate 2 is attached to a base plate 1 horizontally clamped to an upper end of an insulator tube 10 free of movement along a long hole 1a installed in this base plate, and plural pieces of U-shaped metal devices 4 and 5 are clamped to the base plate 1 and the movable plate 2 respectively with a bolt 7. Each roller 6 is supported on these metal devices 4 and 5 free of rotation. And, the movable plate 2 is energized toward the base plate 1 by a tension spring 9 being stretched between the plate and the base plate 1. A stopper rod 11 with a handle 11a is inserted into the insulator tube 10, and the upper end is pierced through the base plate 1 whereby it is made insertable in a hole 2c of the movable plate 2. This stopper rod 11 is energized upward by dint of a spring 14 being interposed between spring bearing plates 12 and 13. And, an electric-car line T is made pinchable between plural rollers 6 free of detachment and vice versa.

摘要： PROBLEM TO BE SOLVED: To attain suppression of a fluctuation in a hanging position due to lateral wind, the high-speed operation of an electric car, and a stringing structure with easy manufacture, installation and maintenance in a catenary type rigid body electric traction. SOLUTION: A cut line for clamping a trolley wire is formed at the lower end of a clamping rigid body 1, a protruding edge for expanding the cut line is formed at both sides thereof, and a locking groove 7 for a hanger 12 is formed at both sides thereof. The hanger 12 is suspended from a catenary wire 13, and a clamping rigid body 1 which clamps the trolley wire 11 is suspended from its lower part. The clamping rigid body 1 is formed into a rectangular tubular shape with four corner curved surfaces, so that displacement due to lateral wind is relieved. The locking grooves 7 on both sides have little wind resistance against the lateral wind, so as to contribute to prevent a position fluctuation by wind pressure. By a flat surface at its upper part, torsion at the time of extrusion forming is prevented. The hanger 12 involves engaging parts 16 for engaging with the locking grooves 7 of the clamping rigid body 1. The engaging parts 16 involves engaging pieces and a pressing metal fitting 26, and obtain strong joining quality with easy joining with the clamping rigid body 1. The length of a hanger bar 15 is adjusted easily by a turn buckle 19.

摘要： PROBLEM TO BE SOLVED: To provide a vibration control tool which can be simply and surely mounted on a trolley wire hanger in use and transmit and damp the wave motion of a trolley wire effectively. SOLUTION: A trolley wire is suspended by a hanging wire via a hanger. A vibration control tool mounted on the curved part of the hanger has a mounting member and an elastic body 9. The mounting member is fixed such that it surrounds the curved part in a predetermined range. The mounting part comprises a base body 11 mounted on the inner side of the curved part 6 and a cover 12 positioned outside the curved part 6 and fitted in the base body 11. The elastic body 9 made of rubber has an arc-shaped support part 9a curved along the curved part and a protruding part 9b protruding downward inside the curved part from the top of the support part 9a and reducing a horizontal cross-sectional area gradually. The wave motion of the trolley wire caused by a sliding pantograph travels on the trolley wire without being reflected by means of elasticity of the elastic body 9 of the vibration control tool and is damped because vibration energy is absorbed.

摘要： PROBLEM TO BE SOLVED: To provide a connecting hanger ear for electric overhead wire having a function for electrically connecting a hanging wire and a trolley wire, capable of reducing a number of components, and capable of facilitating handling such as mounting.
SOLUTION: The connecting hanger ear 1 equipped with a hanger bar 2 having a hook 2c for hooking the hanging wire M and an ear 3 for grasping the trolley wire T is provided with a clamp 4 for grasping the hanging wire M, a conductor 5 extending from the clamp 4, and a sleeve 6 for fixing the conductor 5 on the hanger bar 2. The trolley wire T is supported by the hanging wire M, and the trolley wire T is electrically connected to the hanging wire M through the conductor 5 and the hanger bar 2. By fixing the clamp 4 on the hanging wire M while play is maintained without stretching the conductor 5, the conductor 5 flexibly follows the hanger bar 2 even when the trolley wire T is pushed up by passing of a pantograph. Thus, the electric current can be supplied from the hanging wire M to the trolley wire T through the conductor 5 regardless of the quality of the electric connection state of the hook 2c to the hanging wire M.

摘要： PROBLEM TO BE SOLVED: To effectively transmit the wave motion of a trolley wire at the part where a hanger is mounted and to damp the wave motion with a lightweight and inexpensive structure. SOLUTION: A hanger 3 has a hanger 4 and a grip member 5. A rubber elastic body 7 is vulcanized and integrally fixed to the curved part 6 of the hanger 4. The base of the rubber elastic body 7 wraps the curved part 6 uniformly. A protruding part 9 protrudes toward a hanging wire 2 with a horizontal cross-sectional area thereof gradually from the base 8 and contacts the outer periphery of the cylindrical part 10a of a protection cover 10 fixed to the hanging wire 2 at the protruding end. The wave motion of a trolley wire 1 produced when the pantograph of a train passes transmits a hanging part without producing a large reflection wave by means of the rubber elastic body 7 having a relatively large transmitting coefficient of wave motion. At the same time, vibration energy transmitted to the hanger is damped by the rubber elastic body 7 to prevent the vibration of the trolley wire 1. Accordingly the separating ratio of the trolley wire 1 from the pantograph is reduced to collect electricity stably and the stress to the hanger 3 is reduced to make the life of the hanger 3 longer.
