[0002] The reinforced concrete pipe is a pipeline made of concrete and a steel reinforcement cage and used for conveying fluids such as water, oil and gas; wherein the steel reinforcement cage is usually produced by using a steel reinforcement cage seam welding machine.

[0003] In the actual production process by using the steel reinforcement cage seam welding machine, according to the construction requirements, the main reinforcement of the steel reinforcement cage is manually threaded through the corresponding template guide pipe of the fixed rotating disc and inserted into the corresponding template fixed pipe of the moving rotating disc for fixation. Then, the end of the disc reinforcement is manually fixed and welded on one of the main reinforcements, the moving rotating disc is driven to move away from the fixed rotating disc, and the moving rotating disc and the fixed rotating disc are driven to rotate, so that the disc reinforcement is wound on all the main reinforcements, and manual welding is performed during the winding process, and finally the product steel reinforcement cage is formed.

[0004] For the above-mentioned related technology, the inventors find that the positions of the template guide pipe on the fixed rotating disc and the template fixed pipe on the moving rotating disc are fixed and only one circle, which limits the position of the main reinforcement of the produced steel reinforcement cage, and it is inconvenient to produce steel reinforcement cages of different diameter sizes, and therefore needs to be improved.
