The invention provides a platform for installing a distribution switchgear in place. The platform comprises a guide rail mechanism, a movable portion, a placement portion and multiple rolling mechanism assemblies, wherein the movable portion is movably arranged on the guide rail mechanism; the placement portion is fixedly connected to the movable portion; the multiple rolling mechanism assemblies are arranged on the placement portion side by side and each comprise multiple pressure pin rollers; the axis direction of the pressure pin rollers and the length direction of the guide rail mechanism are consistent. The contact area is enlarged through the pressure pin rollers arranged inside the rolling mechanism assemblies, and the situation that the rolling mechanism assemblies are stressed excessively and damaged due to the too small contact area is avoided.
