Splicing type substation maintenance and overhaul device

The invention provides a spliced transformer substation maintenance and overhaul device, and relates to the technical field of transformer substation maintenance and overhaul. The movement mechanism is mounted at the bottom of the base and drives the base to move; the maintaining and cleaning mechanism is used for cleaning the insulator on the transformer substation in a closed manner; and the lifting mechanism is used for driving the maintaining and cleaning mechanism to ascend or descend. The maintenance and overhaul device is driven by the movement mechanism to move forwards, an insulator is located in two groups of unfolded semicircular shells, the two groups of semicircular shells are driven to clamp the insulator, a driving assembly b drives a sliding seat to slide on a semicircular track, and a maintenance and cleaning assembly is driven to clean the surface of the insulator; the insulator is positioned in the two groups of semicircular shells, so that the insulator is cleaned in a closed manner, dust
