[0002] The standing platform of the scaffolding guardrail is the platform where the operators stand and the safety guardrail to prevent falling when the scaffolding is set up for operation. The insulating scaffolding 41 for electric power operation is made of insulating materials. As one kind of scaffolding, as Figure 1 shown, it usually includes a guardrail frame main body 44 composed of a base 42 and vertical rods 43, horizontal bars 45 and diagonal bars 46 connecting the vertical rods of the guardrail frame, and a standing platform board 47 arranged inside the guardrail frame main body. When performing disconnection or diversion work on overhead lines, or inspection, maintenance, and repair work on substation equipment, etc., it is often necessary to use the insulating scaffolding to assist in completing the high-altitude operation. Therefore, it is particularly important to ensure the safety of the insulating scaffolding. In addition to ensuring that the insulation level of the insulating scaffolding under different usage conditions, the strength, bending deformation, and inclination of the scaffolding itself meet the safety usage standards, according to the latest national standards of the scaffolding, any gap adjacent to the standing platform of the guardrail cannot allow a sphere with a diameter of 400 mm to pass through, and the safety performance of the scaffolding guardrail can be qualified. Therefore, it is crucial to study a set of inspection balls and inspection methods that can detect the gaps of the standing platform of the scaffolding guardrail. Summary of the Invention
