The utility model relates to a guide rope device is put in live working unmanned aerial vehicle exhibition, including unmanned aerial vehicle, exhibition paying out reel, remote controller, steel weight and release, release fixes in unmanned aerial vehicle fuselage below, and inside is equipped with annular electromagnet, and the weight external diameter cooperatees with the annular electromagnet internal diameter to fixed or the release of accessible annular electromagnet, the fixed guide rope of weight afterbody, the guide rope other end is fixed on the exhibition paying out reel through insulating transfer rope, and unmanned aerial vehicle and release pass through remote controller control. Compared with the prior art, the beneficial effects of the utility model are that: control unmanned aerial vehicle through the remote controller and realize crossing over the operation of high hollow wire input guide rope, utilize the electro -magnet to release the realization to the steel weight and put the rope action fast to guide rope exhibition degree of lengthening is prescribed a limit to to the accessible locating piece, and it is very convenient to use, can increase substantially the operating efficiency, reduces intensity of labour, realizes replacing the manual work to carry out the hazardous environment operation by the machine.
