Description

  The present invention relates to a temporary bonding apparatus used for temporary recovery of a power transmission and reception bond.

  A conductor (signal line) for transmitting signal information and the like to the train is attached to the abdomen of the train rail by welding or the like. Basically, the conducting wire is firmly attached to the rail, but the conducting wire may fall off the rail due to vibrations generated when the train passes. Such a drop-off point is often found by an operator during nighttime maintenance and inspection, but the worker is not only working to correct the drop-off point but also performing various types of work. Therefore, when a drop-off point is found, only temporary restoration is performed, and this restoration performed using a welding machine or the like is performed again later.

Therefore, 50N rail temporary bond and 60K rail temporary bond are prepared for the temporary restoration of the conductors that have fallen off the rails, even if the types of rails having different rail bottom shapes are not known on site. There is known a rail common temporary bond that is not necessary and can handle various types of rails (see, for example, Patent Document 1).
