摘要： PROBLEM TO BE SOLVED: To provide a support structure of an overhead line that can improve a power collection capability by suppressing the generation of a reflected wave at a fixed point of the overhead line such as a trolley line.
SOLUTION: In the support structure of the trolley line, the overhead trolley line 11 is supported by hanging from a support structure 2 through a damper 3 at the position separated by a distance L(m) from the fixed point where the trolley line 11 is vertically fixed, in the opposite direction from the wave direction of the trolley line 11. The distance L(m) is set as formula 1, where f is the wave frequency (Hz) of the trolley line, ρ is the density (kg/m) of the trolley line, and T is the tension (N) of the trolley line.

摘要： PROBLEM TO BE SOLVED: To provide an electric traction inspection device which stably runs tracking unevenness and mutual vertical/lateral positional relative fluctuation in a hung line or a feeder so as to provide a high quality inspection result. SOLUTION: An electric traction inspection device 1 is provided with driving carriages 2, 3 on a feeder B, a sensor unit 4, a driven carriage 5 on a hung line A, and a sensor unit 6. Both of the hung line A and the feeder B serve as power supply lines. A driving roller 8 rolling on the feeder B is journalled with a frame 7 for the driving carriages 2, 3 so as to be driven by means of a motor 9. The sensor unit 4, which is connected to the driving carriages 2, 3 by means of a connecting mechanism 18, can be freely rotated relatively in the vertical direction and in the horizontal direction and can be freely displaced relatively in the vertical direction. A driven roller 23 rolling on the hung line A is journalled with a frame 22 for the driven carriage 5. The driven carriage 5, which is connected to the sensor unit 4 by means of a connecting mechanism 24, can be freely rotated relatively in the vertical direction and can be freely displaced relatively in the vertical direction and in the opposing direction. The sensor units 4, 6 are provided with flaw detectors 15, 28 detecting a flaw in the feeder B and the hung line A by means of eddy current.

摘要： PURPOSE:To reduce the height distance from a ceiling to a rigid stringing by laying an angle which can be raised and lowered onto a pair of guide rods suspended from the ceiling and installing an insulator onto the angle, in the captioned device for mini subway. CONSTITUTION:A pair of guide rods 6 are engagement-suspended on the both side parts of a strip-shaped top plate 5 having a crevice, and an elevation plate 7 is fitted in free elevation onto the guide rod 6. The both edges of an angle 10 are fixed onto the opposed side surfaces of a pair of elevation plates 7, and the right and left arms 11a in pair of an insulator 11 are loaded onto the angle 10 so as to shift along the angle 10. At the lower edge of the angle 10, the insulator 11, a rigid stringing 15 having an electric train wire 19 fixed is installed. Since the elevation plate 7 can be adjusted in free vertical movement, the distance from a tunnel ceiling to the undersurface of the rigid stringing 15 can be effectively reduced. Further, in spite of a narrow space, the position of the insulator 11 for the angle 1D can be adjusted freely.

摘要： PURPOSE:To enable to perform slide contact of a collecting device on the vehicle side despite of vertical vibration of a vehicle, by a method wherein positive and negative rigid trolley wires, heretofore installed in a way that an upper trolley wire is installed independently from a lower trolley wire, can be formed integrally to bring it into a fixed state. CONSTITUTION:An insulating plate 6, disposed in parallel to and facing a positive trolley wire, is secured to a support frame 5. The both ends of each of a pair of arms 7 are pivotally attached to a bed plate 4 and a support frame 5 to enable to execute parallelogram motion of the insulating plate 6. However, a leaf spring 8 attached to a bed plate 4 is caused to press an extension part 7a of the arm 7, and the insulating plate 6 is always pressed against the side of the positive trolley wire. The shoe of a positive collector 9 is always brought into slide contact with a trolley wire 2, and negative collectors 10 are attached to the upper and the lower part of a support frame 5. A shoe 10b is forced into slide contact with a negative trolley wire 1. The bed plate 4 is pivotally attached to an axle 14 mounted to a vehicle positioned opposite to the pivotally-mounting part of the arm 7, and is held in a horizontal manner through the force of a mounted spring. This enables smooth slide of a shoe 10b through swinging of the bed plate 4 around the axle 14 during vertical vibration of a vehicle.
