AI Technical Summary
Existing equipment mostly uses a single-stage lifting mechanism with limited stroke, which cannot adapt to the precise positioning of different height work positions and requires multiple manual adjustments, resulting in low efficiency. The lifting and rotation functions are completed in stages, which poses risks of repeated hoisting and transfer of materials and collisions, especially for ton-sized sand boxes with poor safety.
The system employs a two-stage lifting structure consisting of a primary lifting mechanism and a secondary lifting mechanism. Combined with the sliding guides of the limit rod and the stabilizing rod, and the gear transmission of the rotating mechanism, it achieves synergy between multi-stage lifting and rotation, thereby enhancing the stability and precision of the equipment.
The lifting and adjustment range has been expanded, the structural stability of the equipment has been enhanced, the smoothness of lifting and rotating movements has been ensured, shaking and jamming have been avoided, and work efficiency and safety have been improved.
