Reinforcement cage spiral winding method and device

The invention discloses a spiral winding method and device for a reinforcement cage. Comprising the following steps that a mold with a preset diameter is wound with steel bars, and the steel bars are made into intensive spiral stirrups; the multiple main reinforcements are marked at equal intervals; at least three main reinforcements penetrate through the stirrups, at least two carrier rollers are used, the carrier rollers are arranged at the two ends of the main reinforcements, and the stirrups are stretched so that the stirrups can be distributed on the main reinforcements; the distance between the stirrups is adjusted so that the stirrups can correspond to the marks of the main reinforcements, and the two ends of the main reinforcements are welded firstly; moving the carrier rollers to penetrate through the stirrups step by step, and welding at the same time until the reinforcement cage with three main reinforcements is completed; and the other main reinforcements penetrate through the reinforcement cage t
