Electric sleeve and control system special for high-voltage hot-line work robot

The invention discloses an electric sleeve and a control system special for a high-voltage hot-line work robot. The electric sleeve comprises a mounting seat, a shell, a driving device, a rotating device, a sleeve assembly and the control system, the driving device drives the rotating device to enable the sleeve assembly to be in a suitable working state in the required working environment; the sleeve assembly reaches the required opening size through an annular cam block according to the rotation direction and inertia force for being matched with parts of different sizes for mounting and demounting; and the control system adopts a double-closed-loop control operation system to realize smooth and stable speed regulation and high torque output of the electric sleeve special for the high-voltage hot-line work robot. The electric sleeve is simple in structure, hot-line work for direct demounting and mounting of various specifications of bolts and nuts can be conducted, strong electromagnetic interference can be
