Pipe diameter drifting equipment

The utility model discloses pipe diameter drifting equipment which comprises a rack device, a lifting mechanism, a material pushing and blowing mechanism, a material receiving mechanism, a conveying mechanism and a pushing mechanism. A pipe is borne on the rack device, and the lifting mechanism is used for lifting a drift diameter gauge so that the drift diameter gauge can be lifted to be aligned with one end of the pipe on the rack device. The pushing and blowing mechanism is used for pushing the lifted drift diameter gauge on the lifting mechanism into one end part of the pipe and blowing air into the pipe so as to blow out the drift diameter gauge from the tail end of the pipe; and the receiving mechanism is used for receiving the drift diameter gauge blown out from the tail end of the pipe and enabling the drift diameter gauge to roll into a starting station on the conveying mechanism. According to the drift diameter gauge conveying device, cyclic carrying and conveying of drift diameter gauges can be com
