Modularized hot-line work robot system and working method thereof

The invention discloses a modular hot-line work robot system and a work method thereof, the system comprises a modular work robot and a robot on-line and off-line system, the modular hot-line work robot mainly comprises a walking arm module, a case module, a tail end platform and a mechanical work arm, and all the parts are detachably connected. The two walking arm modules are detachably connected to the two ends of the case module and can deflect to the outer side of the wire, and walking on the wire is achieved through walking wheel assemblies and pressing wheel assemblies at the upper ends of arm bodies. The tail end platform can carry various operation tail ends, the mechanical arm can automatically take and place the operation tail ends, and the machine can be used for multiple purposes. The robot online and offline system mainly comprises an unmanned aerial vehicle, an insulating rope suspension assembly and an insulating rope winding and unwinding device which are connected in sequence.
