The invention discloses a lifting device capable of being deployed quickly and wireless relay emergency communication equipment. The lifting device comprises a bottom plate, a lifting rod which is arranged on the bottom plate, and a lifting rod support frame for fixing the lifting rod to the bottom plate; and extension plates which are detachably connected are arranged at the periphery of the bottom plate. The wireless relay emergency communication equipment comprises a relay emergency communication system which is erected between two stations through the lifting device and is in communicationconnection with the two stations through a wireless transmission module correspondingly. By erecting the temporary relay emergency communication system between the two failed stations, important communication services can be quickly and temporarily restored after communication interruption caused by a failure of a power transmission aerial cable network; and access and transmission of voice, video, data and other wide and narrow band multi-services can be carried and realized. In addition, the wireless relay emergency communication equipment is quick and convenient to erect, and a temporary communication platform can be set up in a very short time, so that the emergency use efficiency is improved.
