Description

Technical Field

[0001] The utility model relates to the field of ladder loading, in particular to an automatic ladder loading mechanism for producing pipe segment reinforcement cages. Background Art

[0002] When manufacturing reinforced concrete segments, a steel cage must be placed in a steel mold before pouring concrete. Since the segment structure is approximately strip-shaped, no reinforcement is required in the center. Steel bars are only placed below the surface of the concrete member that is exposed to air. The steel bars are combined to form a complete grid, figuratively referred to as a "reinforcement cage," "reinforcement mesh," or "reinforcement skeleton." A complete steel grid helps constrain concrete and improve the integrity of concrete components. The main function of the steel cage is similar to the load-bearing effect of the longitudinal reinforcement in a column, primarily resisting tension. Concrete has high compressive strength but very low tensile strength. The steel cage can constrain the segment concrete, improving its bending and shear resistance.

[0003] In the production process of steel cage, a large amount of steel bar materials are needed. Therefore, the continuous, large-scale and regular delivery of main bars is closely related to the production efficiency of the steel cage.

[0004] In order to ensure the transportation of steel bars, the existing step loader staggers the movable steps and the fixed steps so that the staggered spacing can accommodate multiple steel bars, thereby realizing the transportation of steel bars. However, the existing step loader can only be used for transportation. Once the transported steel bars contain steel bars of multiple diameters, manual screening and classification or screening and classification through additional equipment are required, which reduces the transportation efficiency.
