The invention relates to the technical field of well completion and cementation, in particular to a tail tube cementing drill pipe rubber plug placing device. The tail tube cementing drill pipe rubber plug placing device comprises a steering wheel, a screw rod and a pressure plug seat, wherein the steering wheel is connected with the upper end of the screw rod; the screw rod is in threaded connection with a bracket; the lower end of the screw rod is screwed connection with the pressure plug seat; and two ends of the bracket are connected with fixed hanging hooks by rotating shafts. The tail tube cementing drill pipe rubber plug placing device provided by the invention has the advantages of capability of safely and smoothly putting the drill pipe rubber plug, convenience in use, time conservation and labor conservation. The shortcomings of time consumption, unsafety, and high possibility of damaging a drill pipe rubber plug center pole and an external rubber skirt due to the need of putting the drill pipe rubber plug into the drill pipe by means of iron hammers and other artificial external force tools in the traditional operation are overcome.
