Step two, according to the diameter of the spiral corrugated pipe (1), looking up a table to find the corresponding scale of the hand wheel (8) and the height of the universal wheel (41), and then adjusting the adjusting bolts of the hand wheel (8) and the universal wheel (41) to enable the transmission rod (42), the universal wheel (41) and the spiral corrugated pipe (1) to be positioned in the same circle; then the spiral corrugated pipe (1) is hung between the support rods (2) through a crane;
Pushing the helical bellows abutting device to move to a position 50-100mm away from the abutting position of the installed helical bellows (1);
Step four, rocking a hand wheel to outwards move the support rods (2) on the left side and the right side of the spiral corrugated pipe (1) for a certain distance, wherein the spiral corrugated pipe (1) freely falls and contacts with the universal wheels (41) and the transmission rods (42);
Step five, a control switch of the motor (9) is turned on, and the spiral corrugated pipe (1) is conveyed to a position 20-30mm away from the butt joint of the spiral corrugated pipe (1);
Step six, respectively starting the lifting device (5) and the adjusting wheel (11), and adjusting the spiral corrugated pipe (1) in the up-down direction and the left-right direction so as to ensure that the spiral corrugated pipe and the butt joint are in an error range;
step seven, after the butt joint of the spiral corrugated pipe (1) is completed, a skid is paved below the spiral corrugated pipe (1), continuous transmission is carried out to enable the spiral corrugated pipe butt joint device to move backwards, the skid is paved at the central position of the spiral corrugated pipe (1), after the skid is paved, the lifting device (5) is reset, and finally the spiral corrugated pipe butt joint device is pushed out, so that the butt joint of the spiral corrugated pipe (1) is completed.
