Large-through-current lightning arrester detection and maintenance equipment

The invention relates to the technical field of lightning arrester maintenance and detection, in particular to large-through-current lightning arrester detection and maintenance equipment which comprises a lightning arrester body and a bottom mounting frame used for mounting the connecting end of the lightning arrester body, and side guide grooves are symmetrically formed in the inner walls of the two sides of the bottom mounting frame; and an electric control type lateral lifting frame is assembled on the bottom mounting frame in a sliding manner. According to the detection and maintenance equipment for the large-through-current lightning arrester, an unmanned operation mode is adopted, so that optical detection and maintenance can be conveniently carried out on the surface of the lightning arrester, and the later maintenance cost of the lightning arrester can be greatly reduced; optical detection is performed on the surface of the lightning arrester in a lifting and surrounding manner, so that the detection
