Description

Lower hanging device for anti-falling device Technical Field The invention relates to the technical field of anti-falling devices, in particular to a hanging device for an anti-falling device. Background When the tower of the power transmission line is maintained regularly, operators need to climb the tower holes to perform overhead operation, and the operators need to wear corresponding anti-falling equipment before climbing the tower. At present, the anti-falling mechanism mainly carries out hanging and hanging downwards in a manual mode and an unmanned aerial vehicle mode, and an operator with abundant experience of climbing a tower on the manual hanging needs to install anti-falling equipment on the tower in advance in an unprotected state, so that the anti-falling mechanism has extremely high safety risk for an installer; When using unmanned aerial vehicle to hang down anti-falling device, what adopt is that the disc clamp of opposition anchor clamps at anti-falling device is got down, in pressing from both sides and getting the in-process, need guarantee that anchor clamps are in the below of disc all the time, reduce anchor clamps again and just can take off anti-falling device, when facing novice flight unmanned aerial vehicle, anchor clamps press from both sides and get the disc and need guarantee the position between anchor clamps and the disc and just can take off, the scope of activity is less on the use of unmanned aerial vehicle place novice, influences the success rate of hanging down using unmanned aerial vehicle.
