摘要： PROBLEM TO BE SOLVED: To move an electric traction inspection device stably, avoiding obstacles on a track. SOLUTION: An electric traction inspection device 1 comprises a traveler 2 which self-drives on a hang line M by a motor 8 and a controller 3 which moves on a lower part of a trolley line, hung by the traveler 2 with a plurality of supporting arms 4. A hook 7 is set at the traveler 2 which involves with a joint 4a of the supporting arms 4 by a hook driving motor and breaks them away. The supporting arms 4 are set in plurality with a same interval each other to a forward direction, elected by an arm driving motor 10 at the controller 3 and connected so as to be able to invert. The joint 4a involves with the hook 7 on the traveler 2 at the election position and the supporting arms 4 avoid obstacles on the track at the inverse position. An optical inspection device 13 is set respectively at the traveler 2 and the controller 3 and when it detects obstacles on the forward direction of each supporting arm, the controller 3 will control a driving motor 9, 10 so as to invert and elect the hook 7 and the supporting arms 4.

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： PROBLEM TO BE SOLVED: To provide a damper for suppressing relative vibration between two suspension wires with frictional resistance between members. SOLUTION: In the damper 1, two suspension wires M suspended so as to support different trolley wires downward and extend substantially in parallel are interconnected, and the relative vibration between the two suspension wires M is suppressed by the frictional resistance between the members. A body 2 to be fixed to one suspension wire M and a turning arm 8 pivoted by the other suspension wire M so as to move relatively in the axial direction is pivotably adhered to the body. The turning of the turning arm 3 by the relative vibration between the two suspension wires M is suppressed by the frictional resistance by a frictional resistance member 4. The frictional resistance by a frictional resistance member 4 can be adjusted by position change of a spring bearing member 11. COPYRIGHT: (C)2005,JPO&NCIPI

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.
