[0074] During use, the lifting rod 2 and the central connecting plate 4 move up and down to drive multiple support rods 8, so that multiple hook rods 5 can be extended or retracted, so as to be suitable for different specifications of steel cages 1. It is highly versatile, easy to use, and low in cost. Meanwhile, this solution utilizes the cooperation between the lifting rod 2 and the central connecting plate 4, so that the lifting rod 2 drives multiple hook rods 5 to unfold or retract through multiple support rods 8, which is simple to operate and saves time and effort. In addition, the multiple support rods 8 provide a certain degree of support for the multiple hook rods 5, ensuring the strength of the entire device and extending its service life.

[0075] Furthermore, the support rod 8 connects the lifting rod 2 and the hook rod 5. The up-and-down movement of the lifting rod 2 drives the support rod 8 to move and rotate synchronously, thereby enabling the hook rod 5 to retract and extend, adapting to the hoisting requirements of steel cages 1 with different diameters. During hoisting, the lifting rod 2 bears an upward pulling force, and the hook rod 5 is in an extended state, further enhancing the fixed stability of the steel cage 1.

[0080] Preferably, in this embodiment, a pair of ear plates 9 are fixedly installed on the lower side of the above-mentioned multiple hook rods 5 respectively, and the upper end of each support rod 8 extends into the corresponding pair of ear plates 9 and is rotatably connected to the corresponding pair of ear plates 9 through a pin.

[0081] Preferably, in this embodiment, ear plates 9 are evenly spaced and fixedly installed on the circumference of the central connecting plate 4, and U-shaped grooves are respectively provided at the corresponding ends of the multiple hook rods 5.

Wide range of applications: The device, with its adjustable lifting rod and support rod design, can flexibly adapt to steel cages of different diameters to meet diverse construction needs.

[0092] 2. Simple structure and easy installation: The overall structure is compact and reasonable, with few parts, making installation and disassembly convenient, saving construction preparation time and improving work efficiency.

[0093] 3. Improve hoisting accuracy: The position of the hoisting rod can be precisely fixed through the adjustment of the central connecting plate and bolts, so as to achieve stable hoisting and precise docking of the steel cage, reducing deviation and damage.

[0094] 4. Enhanced safety: The hook is equipped with a cover and a safety pin to effectively prevent the steel cage from falling off during hoisting, ensuring the safety of construction personnel and equipment.

[0095] 5. Improve construction efficiency: The up-and-down movement of the lifting boom drives the support rod and hook rod to work synchronously, enabling rapid folding and unfolding, shortening the preparation and adjustment time for hoisting, and improving the overall construction progress.
