Further, on this main operation platform, offer a hole, the position of this perforate is with this electrode rotary device when the grafting by electrode rotary during to this main operation platform, and three-phase electrode can be advisable through this perforate.
Further, the neat device of this electrode stack also comprises an assistance platform, and this assistance platform is arranged at this main operation platform perforate side top, to carry out grafting.
Further, when needs carry out electrode grafting, the neat dolly of this electrode stack is opened back, and three-phase electrode, through the perforate of this main operation platform, along with conductive cross arm drops to electrode lowest order together, carries out online grafting to three-phase electrode on this assistance platform.
Further, this main operation platform arranges two tracks for the neat carriage walking of this electrode stack.
For achieving the above object, the present invention also provides a kind of electrode stack neat dolly, electrode stack for LF stove is neat, it is characterized in that: the neat dolly of this electrode stack comprises dolly body, Electrohydraulic push rod and Electrohydraulic push rod bearing, this dolly body is connected with Electrohydraulic push rod, to realize the neat dolly of this electrode stack by this Electrohydraulic push rod in the walking of this main operation platform, this Electrohydraulic push rod bearing is connected with this Electrohydraulic push rod.
Further, this Electrohydraulic push rod bearing is fixed on a relative side of main operation platform perforate.
Further, on the direction of travel of this main operation platform dolly, be provided with limit switch, to realize interlocking with miscellaneous equipment.
Further, filling sand in the neat dolly of this electrode stack, the impact while declining to reduce electrode.
Further, on this Electrohydraulic push rod and Electrohydraulic push rod bearing, a protective cover is set.
Further, except electrode grafting, the neat dolly of this electrode stack of all the other times is all the time in outputing position.
Compared with prior art, the neat dolly of electrode stack of the neat device of a kind of electrode stack for LF stove of the present invention and use thereof is by arranging the neat dolly of main operation platform, assistance platform and electrode stack, to make operative employee in the neat operation of the enterprising windrow of main operation platform when the neat operation of electrode stack, during grafting, make operative employee on assistance platform, carry out grafting, greatly reduce the unsafe factor of workman when work, improved its operating efficiency.
