A hook assembly based on an ingot mold anti-unhooking and a hoisting equipment

Abstract

This utility model discloses a hook assembly and lifting equipment based on anti-disengagement of steel ingot molds, relating to the field of steel ingot mold lifting. The key technical points are: it includes an installation part and an elastic telescopic part located below the installation part. A hook is installed on the telescopic part of the elastic telescopic part. The elastic telescopic part has a high-strength spring and a damper. The effect is that when the hook lifts the steel ingot mold, the shaking and impact forces generated during the lifting process due to starting and stopping inertia and running vibrations are first transmitted to the elastic telescopic part. The high-strength spring in the elastic telescopic part absorbs some energy through its own elastic deformation, reducing the impact force. At the same time, the damper plays a buffering role, effectively dissipating the remaining energy, reducing the vibration amplitude and frequency, thereby reducing the periodic alternating load borne by the connection between the hook and the steel ingot mold, avoiding hook fatigue fracture, preventing relative displacement or disengagement between the steel ingot mold and the hook, and ensuring lifting safety.
