The invention relates to a method for synchronously lifting an electrode by three cylinders, which comprises a circular electrode hydraulic elevator, the circular electrode hydraulic elevator is provided with a rack, three hydraulic cylinders are uniformly distributed on the peripheral surface of the rack at 120 degrees, and when the three hydraulic cylinders work, a hydraulic synchronous valve is adopted to ensure that the three hydraulic cylinders synchronously lift; the three hydraulic cylinders are distributed in a central symmetry mode and installed in a hinged mode, and the load electrode can be automatically centered during synchronous lifting. According to the three-cylinder synchronous electrode lifting method and the three-cylinder synchronous electrode lifting executing method of the circular electrode hydraulic elevator, the three hydraulic cylinders synchronously move to achieve lifting movement of the electrode, the problems that the lateral force of the hydraulic cylinders is too large due to stress unbalance loading and unbalance loading of a single-cylinder mechanism is difficult to adjust and even cannot be adjusted are solved, and the working efficiency is improved. And the overall occupied space is small, the machining and manufacturing difficulty is reduced after the size of the hydraulic cylinder is reduced, the precision and the manufacturing cost are easier to control, and mounting and dismounting are more convenient and safer.
