The docking frame 340 is installed on the positioning slide seat 320, enabling it to drive the docking frame 340 to move to a specified position to achieve precise alignment with the steel reinforcement cage positioning member 230. Through the structure of the slide rail and the slide seat, the problem that the position of the steel reinforcement cage positioning member 230 may change is solved, ensuring that no matter where the steel reinforcement cage is located, the correct docking point can be found by adjusting the positioning slide seat 320, improving the flexibility and accuracy of positioning.

[0046] Furthermore, the positioning and docking assembly 350 includes a telescopic frame 351 that is slidably engaged with the docking frame 340.

When the stabilizing rod 233 of the positioning member 230 enters the stabilizing groove 363 of the movable frame base 362, the stabilizing screw 364 locks the stabilizing rod 233 to ensure the stability of the steel reinforcement cage in the vertical direction. The stabilizing seat 366 and the supporting telescopic frame 351 in the moving groove 365 further enhance the rigidity and stability of the overall structure. Through a multi-point contact and locking mechanism, the triangular stabilizing component 360 solves the lateral force and instability factors that may be encountered during the placement of the steel reinforcement cage, ensures the verticality and stability of the steel reinforcement cage in the pile foundation groove, and improves the safety and quality of construction.

[0051] In actual operation, the steel reinforcement cage is first fixed on the positioning frame 210 through the hanging component 220, and then the positioning and alignment mechanism 200 slowly moves the steel reinforcement cage above the positioning seat 100 through the top support and clamping component 240 and the guiding and sliding component 250. During this process, the positioning member 230 cooperates with the positioning and docking mechanism 300 to ensure the accurate placement position of the steel reinforcement cage. The positioning slide rail 310 and the sliding seat provide lateral sliding support, while the docking frame 340 and the triangular stabilizing component 360 ensure the stability and firmness of the steel reinforcement cage during the final placement. In this way, the device can effectively solve the problems of inclination, displacement, and inaccurate positioning that are prone to occur during the placement of traditional pile foundation steel reinforcement cages, and improve the construction efficiency and project quality.
