AI Technical Summary
The existing crane hooks are connected to the hook base via threaded connections and fasteners. Long-term use leads to reduced connection stability, posing safety hazards and affecting the practicality of the device.
A hook for a bridge crane was designed, employing a reinforcement mechanism and an anti-detachment mechanism. The hook is reinforced to the mounting base through components such as sliding rods, sliders, connecting rods, U-shaped frames, and clamps, while anti-detachment buckles and torsion springs prevent material from falling off.
This enhances the connection stability between the hook and the mounting base, prevents materials from falling off, and improves the safety and practicality of the crane.
