The invention provides a specific dismounting platform for a megavolt bushing terminal. The specific dismounting platform comprises a dismounting mechanism and a monitoring mechanism arranged on the upper end of a hoisting mechanism of a crane, wherein the dismounting mechanism comprises a workbench arranged on the upper end of the hoisting mechanism. A working aperture is arranged in the bottom of the workbench, and an annular pedestal cooperating with the upper end of a bushing is arranged in the working aperture through a support. A plurality of leading screws are arranged on the annular pedestal, a lifting supporting plate is arranged on the leading screws, and a through hole is arranged in the center of the lifting supporting plate corresponding to the terminal. The lifting supporting plate is provided with a lifting aperture corresponding to the leading screws, a hoop is arranged above the lifting supporting plate corresponding to the through hole, and a driving mechanism is arranged on the leading screws corresponding to the lifting supporting plate. A bushing terminal can be dismounted with simple tools, and returning to the factory for processing or destructiveness dismounting are not necessary. The replacing time of a bushing terminal and work hour are greatly shortened, the work efficiency is improved, and excellent economic benefit is achieved.
