Background
The prestressed reinforcement cage is a reinforcement mesh framework of a conical concrete electric pole and a cylindrical concrete pipe pile, and the spiral reinforcement can be wound only when the reinforcement cage is stretched to a certain tensioning tension. Currently, there are two common tensioning processes in the industry:
(1) Tensioning by using an electric hoist, fixing one end of a steel reinforcement cage on a steel frame upright post, connecting the other end of the steel reinforcement cage with an electric hoist hook, manually operating the electric hoist to operate, tensioning the steel reinforcement cage to a tensioning force considered by an operator to be proper, and then winding a spiral rib. Tension force detection is not carried out in the whole tensioning process, the tension force detection is completely judged by the experience of workers, and the tension force is large or small in production, so that the spiral reinforcement of the reinforcement cage is wound loosely and unevenly, and the quality cannot be guaranteed; and when the tension pressure of the electric hoist is overlarge, potential safety hazards exist.
(2) A commercial semi-automatic winding machine is purchased, and the device adopts the mechanical structure tensioning of a worm gear and a worm, and the tensioning force is not detected.
