[0043] In practical applications, when the molten iron on the inner wall of the official film solidifies, the cast pipe is formed. When the cast pipe cools down for a period of time, the pipe pulling machine 7 moves forward along the track to the double-tube centrifugal pipe casting machine 2, and the push rod 3 withdraws the cast pipe. The pipe pulling machine 7 opens the puller to clamp the cast pipe, and then the pipe pulling machine 7 retreats to pull out the cast pipe. After the pipe pulling machine 7 pulls out a distance, the pipe hosting machine 5 catches the cast pipe, and then the pipe kicking machine 4 kicks the cast pipe to the pipe transport device 6 to complete the production process. In the technical solution provided in this application, an electric cylinder piston rod is used. In some embodiments, other forms of push rods, such as hydraulic push rods, can also be used to play the role of pushing out the cast pipe, which is not specifically limited in this application.
