AI Technical Summary
Technical Problem
Traditional winch hooks are prone to swaying due to inertia when lifting heavy objects, which can cause the material to swing and fall, resulting in insufficient safety performance.
Method used
An anti-sway mechanism is adopted, which uses the principle of electromagnetic damping to generate current by cutting magnetic field lines in the magnetic field through a guide rod, driving the motor to rotate the magnetic ring, reducing the sway amplitude, and combined with a buffer mechanism to improve stability.
Benefits of technology
It effectively prevents materials from swaying due to inertia during hoisting, improving safety and stability, preventing materials from falling, and reducing damage to the hook.

Abstract
The application discloses a straight-arm type aerial work platform winch hook mechanism, which comprises a top plate and a shell, a moving plate is slidably connected in the shell, a hook body is arranged at the lower end of the moving plate, a buffer mechanism for buffering the moving plate is arranged in the shell, a guide rod is fixedly connected to the upper end of the shell, the guide rod is made of steel, a conductor is arranged in the guide rod, the guide rod is connected with the lower end of the top plate through a universal joint, two symmetrically arranged fixing rods are fixedly connected to the lower end of the top plate, and horizontal plates are fixedly connected to the lower ends of the fixing rods. The application has the advantages that the anti-swing mechanism is arranged, the guide rod is reduced in swing amplitude under the action of a magnetic field according to the electromagnetic damping principle, and is gradually stabilized until the swing is eliminated. Compared with a traditional hook mechanism, the hook mechanism can effectively avoid the swing of materials due to inertia in the process of hoisting, avoids the falling of the materials, and greatly improves the safety performance of the device.
