Definitions

  • An electrode connecting device for furnaces as invented differently from this invention wherein a new electrode is held by a carriage provided on a MOTO arm (linear actuator) has the following disadvantages: for connecting a new electrode with an old electrode a human operator is required to get on the top of a furnace and make alignment of the electrodes; a special working operation is required to prevent the hook of a crane from rotating; there is a risk that adjacent electrodes would be damaged by the stopper; and another special working operation is required to demount the device from the new electrode.
  • FIG. 1 there is illustrated an electrode connecting device according to this invention.
  • the electrode connecting device of this invention has the following advantages: the structure of the device is relatively simple; it is unnecessary for a human operator to get near an old electrode to connect a new electrode with the old electrode; since it is easily possible to displace the wheels 7 inwardly and to return them to their original position, itis easily possible to effect alignment of the electrodes; since the present device can be remotely operated by only a human operator, a new electrode can be connected with an oldelectrode without risks that the human operator might fall down from the top of a high furnace and the human operator might be exposed to high heat; the present device is efficient; and the present device is useful in industry.
  • a device adapted to be disposed in a predetermined position over a furnace for connecting a new electrode held in the device to an old electrode held in the fumaceQcomprising an upper guide for supporting rods, a lower guide for supporting rods, a plurality of outwardly curved supporting rods connected between said upper and lower guides, said upper and lower guides movably holding a new electrode.
  • first driving means each mounted on one end of each of said supporting rods for pulling the respective rod
  • wheels each rotatably mounted on the center of each of said supporting rods
  • second driving means associated with each of said respective wheels for rotating them, said wheels being moved into contact with the new electrode when said supporting rods are pulled by said first driving means, whereby when said second drivingmeans is operated to rotate said wheels the new electrode is rotated and moved toward said old electrode to be screw engaged therewith.
  • each of said first driving'means includes a motor, a worm secured to the shaft of said motor, a worm wheel engaged with said worm, a pinion connected through a shaft to' said worm wheel and a rack formed on one end of the supporting rod and engaged with said pinion.
