The invention discloses a replacement process for a lifting steel wire rope of a vertical shaft multi-rope friction lifter. The replacement process comprises the following steps: (1) placing a new rope plate and an old rope receiving plate at proper positions at the balance hammer side of an upper shaft mouth, and stopping a tank cage at the position of the upper shaft mouth; (2) at the upper shaft mouth, connecting a traction rope with new and old ropes by the rope head of the new rope via a guide wheel at the balance hammer side; (3) starting a lifter to descend the tank cage by a hoist at the speed of 0.4m/s; (4) respectively clamping the new rope at a hoist house, an upper hoisting sheave and a lower hoisting sheave by compound board cards and then lifting the new rope, and dismounting the traction rope for connecting the new rope with the old rope; (5) reversely driving the hoist at the speed of 0.4m/s, and lifting the tank cage to the upper shaft mouth; (6) arranging an anti-running device and a rope tightener, and descending the tank cage until the balance hammer is lifted to the upper shaft mouth; (7) dismounting the anti-running device and the rope tightener, and mounting a rope clamper; (8) cutting off the old steel wire rope below a hoist roller, and replacing the old rope with the new rope; and (9) after the tank cage is lifted to the upper shaft mouth, mounting the rope clamper, connecting the new rope with a wedge-shaped rope, regulating the rope length, dismounting the rope clamper, and implementing pilot run after the rope replacing process is completed.
