Elevator energy storage inertia wheel system and elevator

The utility model discloses an elevator energy storage inertia wheel system and an elevator, and the system comprises at least one driving wheel which is a pulley which is connected with a driving main machine through a rope or a belt in the elevator and synchronously rotates along with the driving main machine; each driving wheel is provided with a centrifugal brake which coaxially rotates, the inertia wheel and the driving wheels are coaxially arranged, and the inertia wheel is connected with the driving wheels through the centrifugal brakes; the centrifugal brake can be attached to the inertia wheel when the rotating speed of the driving wheel reaches a set threshold value, so that the inertia wheel synchronously rotates along with the driving wheel to store energy; and the centrifugal brake can be separated from the inertia wheel when the rotating speed of the driving wheel does not reach a set threshold value, so that the inertia wheel releases energy under the inertia effect. The inertia wheel energy st
