Live-line work gravity self-locking suspension tool

The utility model discloses a live-line work gravity self-locking suspension tool, which comprises a wire hook, a gravity locking block and a self-locking mechanism, the bottom of the wire hook is connected with a sliding rod, the bottom of the sliding rod is connected with a baffle plate, the sliding rod is in sliding fit with the gravity locking block, and the bottom of the sliding rod is connected with the baffle plate for preventing the gravity locking block from being separated. The self-locking mechanism is connected with the gravity locking block, when the gravity locking block is located at the lowest position, the self-locking mechanism closes the wire hook opening, and when the gravity locking block is located at the highest position, the self-locking mechanism opens the wire hook opening. The lifting device can be carried by an unmanned aerial vehicle, is thrown and hung on a lead, is self-locked through gravity, can be used for lifting an insulating rope ladder, and is convenient to operate. 本实用新型
