AI Technical Summary

Technical Problem

T-beam reinforcement cages are prone to deformation during transportation and assembly, and the limited space in the mold makes assembly difficult. Conventional hoisting methods are unstable, affecting production efficiency.

Method used

Design a special lifting device that includes a truss, chain, and chain lock. The truss consists of a bottom strip frame and a top longitudinal beam, connected by a figure-eight brace. Combined with a fixed seat and chain lock, it achieves stable lifting, adapts to the structure of T-beam steel cage, and avoids deformation.

Benefits of technology

It enables the smooth hoisting of T-beam reinforcement cages, avoids deformation, improves production efficiency and hoisting stability, adapts to different length requirements, and enhances the rigidity and durability of the hoisting equipment.

Abstract

The utility model discloses a lifting appliance for a T-beam reinforcement cage, which belongs to the technical field of T-beam reinforcement cage lifting equipment, and particularly structurally comprises a truss, chains and chain lock catches, the top side of the truss is symmetrically and fixedly connected with a fixed seat, the center of the top side of the fixed seat is provided with a hanging hole for hanging a crane hook, and two ends of each chain are provided with two chain lock catches. The multiple sets of chains are evenly arranged in the length direction of the truss, each set of chains comprises four chains, the middle of each chain is fixedly connected to the truss, and each chain lock catch is connected to a reinforcing steel bar of a T-beam reinforcing steel bar cage in a hung mode. A plurality of groups of chains and chain lock catches are used for uniformly hanging steel bars on a top plate of the T-beam steel reinforcement cage, and the truss with a strip-shaped frame structure is matched, so that the hoisting is stable and reliable, the stress is uniform, the T-beam steel reinforcement cage is stably hoisted and is not deformed, and the damage to the T-beam steel reinforcement cage is avoided; the complete reinforcement cage is welded outside the mold, the space is large, and welding manufacturing is facilitated.
