The invention relates to the field of auxiliary overhaul devices of overhead cables, and specifically relates to an overhead cable auxiliary overhaul device used for electric power overhaul. The overhead cable auxiliary overhaul device comprises a main body, a movement mechanism, a lifting and pulling mechanism, a slow descending mechanism, a limiting mechanism and a connection mechanism. By arranging the movement mechanism, the main body can be conveniently moved or fixed along with the movement of maintainers, and the use flexibility of the device is improved. By arranging the limiting mechanism, a cable can be conveniently placed in the main body, the cable can be prevented from being accidentally disengaged from the main body, and the use safety of the device is ensured. By arranging the lifting and pulling mechanism, an exposed handle can be drawn back into the main body, dust and other foreign matter are prevented from entering the main body, and the attractiveness and cleanliness of the device are improved. By arranging the slow descending mechanism, the release speed of a safety rope can be freely regulated, and the use comfort degree of maintainers is ensured. By arrangingthe connection mechanism, a lifting hook is prevented from being accidentally disconnected from the maintainers, and the use safety of the device is further ensured.
