3. The pipe pulling apparatus of claim 1, wherein: the frame includes support and crane, and the crane can go up and down along the support, and traction mechanism sets up on the crane.
4. The pipe pulling apparatus pulling method of claim 1, comprising the steps of:
s1, lengthening the traction tube and pushing the traction tube: the pipe joint is connected to the traction pipe to lengthen the length of the traction pipe, and after the traction pipe is sent to the traction mechanism, the traction pipe is moved to one side of the forming equipment by alternately pushing the traction pipe through a drawing assembly of the traction mechanism until the traction pipe is moved to the output end of the pipe forming equipment;
s2, pulling the pipe and disassembling the pipe joint: after the traction tube is connected with the pipe, the traction tube is driven to be far away from the forming equipment by alternately pulling the traction tube through the pulling assembly of the traction mechanism, and the pipe joint is detached from the traction tube in the process so as to reduce the length of the traction tube.
5. The method according to claim 4, wherein adjacent pipe sections are threadably connected, and further comprising an elastic mechanism comprising a rotator for driving the grasper to rotate forward or reverse and a grasper for grasping or releasing the pulled pipe section, the grasper being coaxial with the grasper, the rotator being movable in the axial direction of the pipe;
in the steps S1 and S2, the action of increasing the number of pipe sections of the traction pipe or gradually disassembling the pipe sections of the traction pipe in the pushing or pulling process is automatically realized through the cooperation of the elastic mechanism and the traction mechanism.
6. The method according to claim 5, wherein the frame comprises a bracket and a lifting frame, the lifting frame can lift along the bracket, and the traction mechanism is arranged on the lifting frame; the traction method further comprises the following steps:
s3, reducing the height of the pipe traction device: after the step S2 is completed, the lifting frame is lowered through the lifting frame, so that the traction mechanism on the lifting frame moves downwards, and a moving space is provided for normal production of the pipe.
7. The method according to claim 6, wherein the lifting frame is provided with a moving wheel; and step S3, after the lifting frame of the pipe traction device is lowered until the moving wheel is contacted with the ground, the pipe traction device is pushed away by the moving wheel.
