Abstract
The invention relates to a cathode lifting device used for an aluminum reduction cell, comprising a motor, ball screw jacks and triangle plates. The motor is connected with two sets of worm-and-wheelgears parallel with two sides of the reduction cell by couplings. The extension end of each set of worm-and-wheel gear is connected with the left and right of the two sets of ball screw jacks. The extension ends of the ball screw jacks are connected with pull rods below which the triangle plates are arranged. The triangle plates are installed on a long axis and rotate around the long axis. The long axis is fixed on a crossbeam by a supporting axis seat. The triangle plates are connected with bus hanger plates to drive the bus hanger plates to move vertically. The worm-and-wheel gears at two sides drive four sets of ball screw gears and the load borne by each set of ball screw gear is a quarter of the total load of the cathode lifting device, thus avoiding the ball screw gears from resulting in such detects as complex gears and large external dimensions due to too heavy load. The cathode lifting device is especially suitable for the aluminum reduction cell with current intensity more than 300kA.
