The purpose of this utility model will overcome above-mentioned deficiency exactly, and a kind of time saving and energy saving ladle refining furnace electrode adjusting gear is provided.
For achieving the above object, the ladle refining furnace electrode adjusting gear that the utility model is designed, comprise the column that can move up and down along lifting idler pulley, described column top is provided with horizontal mounting plate, be provided with transverse arm on the described horizontal mounting plate, the end that described transverse arm extends to ladle refining furnace ladle top is equipped with electrode clamping mechanism, it is characterized in that:
Described transverse arm both sides are provided with mounting base, have the oval hole on the described mounting base, and described transverse arm is fixed on the horizontal mounting plate by the standing bolt adjustable ground that passes the oval hole;
Described horizontal mounting plate both sides are provided with horizontal adjustment jackscrew mechanism, described horizontal adjustment jackscrew mechanism is comprised of the lateral adjustments bolt that is fixed on the horizontal jackscrew base of horizontal jackscrew on the horizontal mounting plate and passes the bolt hole of the horizontal jackscrew base of horizontal jackscrew, and described lateral adjustments bolt tail end cooperates with the mounting base butt;
Both sides, described transverse arm middle part are provided with vertical adjustment jackscrew mechanism, described vertical adjusting jackscrew mechanism is by being fixed on vertical jackscrew on the transverse arm vertically to the jackscrew base with pass vertical jackscrew and vertically form to vertical adjusting bolt of the bolt hole of jackscrew base, the tail end of described vertical adjusting bolt cooperates with the block butt, and described block is fixed on the horizontal mounting plate.
Further, described horizontal adjustment jackscrew mechanism is provided with 4 covers, is installed in respectively on the dual-side of horizontal mounting plate end, and is corresponding with 4 mounting bases of transverse arm both sides.
Further, described vertical adjustment jackscrew mechanism is provided with 4 covers, and in twos on the symmetrical dual-side that is installed in the transverse arm middle part, and 2 covers of homonymy are vertically adjusted and shared 1 block between the jackscrew mechanism.
Again further, described column and horizontal mounting plate junction are provided with the reinforcement gusset.
The utility model has the advantage of: change the screw that is connected with column on the transverse arm into long strip shape oval hole by circle, vertically adjust distance to increase electrode.Respectively installing several groups between lifting column and transverse arm laterally adjusts and vertical jackscrew of adjusting, unclamp between column and transverse arm be fixedly connected with bolt after, utilize the thrust of jackscrew to finish Adjustment of displacement on the transverse arm all directions, adopt this inflation method, greatly shorten electric-pole horizontal arm and adjusted the required time, originally electrode once being adjusted needs 5 people to spend time about 6 hours, only needs 2 people spend just can finish in more than 1 hour after the improvement.Alleviate serviceman's labour intensity, improved the security of upkeep operation, greatly shortened the upkeep operation time.
