The invention discloses a multifunctional live overhauling device which comprises a stand, a lifting mechanism, a fixed mechanism, a rotation motor, a pitching motor, a rotation regulation mechanism and a pitching regulation mechanism, wherein the fixed mechanism is fixedly arranged on the stand, and is detachably and fixedly mounted on a
transformer substation equipment stand; the rotation regulation mechanism comprises a rotating seat, the rotating axis of the rotating seat and the lifting mechanism is the
horizontal axis X, and the rotation motor is in transmission connection with the rotating seat to drive the rotating seat to rotate along the
vertical axis and further drive the lifting mechanism to rotate along the
vertical axis; the pitching motor is in transmission connection with the pitching regulation mechanism, and the pitching regulation mechanism is connected with the rotating seat and the lifting mechanism to control pitching regulation of the lifting mechanism relative to the
horizontal axis X through the pitching motor; an insulating rod is arranged at the uppermost end of the lifting mechanism, and multiple sets of functional devices are additionally assembled, and are all provided with connecting structures which can be detachably connected to the insulating rod. The multifunctional live overhauling device has the advantages that live operation can be carried out, the power outage time of equipment can be reduced,
economic benefits can be improved, and aloft work risks can be reduced.
