AI Technical Summary
Existing concrete block clamps only apply force in two directions to clamp the blocks, and lack bottom support, which makes the blocks prone to slipping during hoisting and transportation, endangering the safety of construction workers.
A clamping device is designed, comprising a clamping assembly, a connector, a bottom support assembly, and an aligning assembly. Through a mechanical structure driven by a hydraulic rod and a motor, it achieves multi-point support and stable clamping of concrete blocks, ensuring stability during hoisting and aligning the blocks before clamping.
This effectively prevents concrete blocks from slipping during hoisting, protecting the safety of construction workers and improving the stability and safety of the construction process.
