[0002] A circular pier column reinforcement cage is a structure used in construction, primarily to support and reinforce concrete structures. It consists of a series of steel bars welded or tied together at specific spacings and shapes, forming a three-dimensional mesh structure. The main components of a circular pier column reinforcement cage include main reinforcement, stirrups, and connecting bars. During construction, the cage is first manufactured to specifications according to the design requirements. It is then hoisted and lowered into a pre-excavated foundation pit, where concrete is poured. Once the concrete hardens, a solid circular pier column structure is formed.

[0003] The round pier column reinforcement cage is lifted by a lifting device. The existing round pier column reinforcement cage lifting device mainly includes a hanger, a lifting rope and a hook. The hanger is fixed on the lifting arm, one end of the lifting rope is connected to the hanger and the other end is connected to the hook, and the hook hooks the round pier column reinforcement cage; the round pier column reinforcement cage is then lifted by raising and lowering the lifting arm or winding up the lifting rope; however, the hanger is fixed, and the connection end of the lifting rope and the hanger and the node where the hook hooks the round pier column reinforcement cage are not on the same vertical line, so the lifting rope will be tilted, and the lifting rope will generate a lateral pulling force on the round pier column reinforcement cage, which can easily cause the round pier column reinforcement cage to deform.

[0023] In one embodiment, Figure 1-Figure 3 As shown, the adjustment mechanism 500 includes an adjustment motor 510, a rotating disk 520 and a plurality of pushing components. The adjustment motor 510 is fixed to the bottom of the central body 100 of the sling and the rotating disk 520 is provided on the output end of the adjustment motor 510. The end surface of the rotating disk 520 is provided with a plurality of rotating disks 520 close to the edge position and the plurality of rotating disks 520 correspond to the plurality of pushing components one by one. The pushing components are slidably provided on the corresponding radial connecting rod 220, and the eccentric boss 570 is provided with an end intersecting with it.
