s5, the limiting device (2) and the operation platform (3) are driven by the lifting device (1) to ascend, the limiting device (2) is used for limiting the support of two telegraph poles, and the contact rolling balls (213) are used for contacting the telegraph poles so as to reduce the moving friction force, so that the two telegraph poles fix the operation platform (3) in the peripheral direction, and the operation platform (3) can be prevented from shaking when an operator works on the operation platform (3) to influence the operation convenience;
and S6, when the operation platform (3) is positioned below the transformer, the lifting driving electric cylinder (13) is closed, the lifting device (1) is in a static state, and then the worker can freely move on the operation platform (3) to overhaul the transformer.
2. The use method of the power equipment maintenance system according to claim 1, characterized in that: and reinforcing ribs (322) are arranged at the connecting positions of the fixed mounting plate (32) and the operating platform (3).
3. The use method of the power equipment maintenance system according to claim 1, characterized in that: the lifting device (1) is composed of a lifting bottom plate (11), a lifting top plate (12), a lifting driving electric cylinder (13), a lifting driving rod (14) and a linking reinforcing rod (15), the lifting bottom plate (11) and the lifting top plate (12) are both horizontally arranged, the lifting top plate (12) is positioned above the lifting bottom plate (11), the lifting top plate (12) is connected to a limiting device (2), the lifting driving rod (14) is provided with a plurality of lifting driving rods (14) which are arranged on two sides of the lifting bottom plate (11) and the lifting top plate (12) in an X-shaped cross mode, the lifting driving rod (14) at the bottommost part is linked to the lifting bottom plate (11), the lifting driving rod (14) at the topmost part is linked to the lifting top plate (12), the linking reinforcing rod (15) is provided with a plurality of reinforcing rods (15), two sides of the reinforcing rod (15) are respectively installed on linking points of the lifting driving rods (14) which are arranged in an X-shaped cross mode on two sides, the lifting driving electric cylinder (13) is transversely arranged on the lifting bottom plate (11), and the output end of the lifting driving electric cylinder (13) is connected to a connecting reinforcing rod (15) at the bottommost part.
4. The use method of the power equipment maintenance system according to claim 1, characterized in that: two sides of the operating platform (3) are respectively provided with a guard rail (34).
