AI Technical Summary
In existing lifting equipment, the failure of the torsion spring in the reset rod causes the hook to fail to reset accurately, increasing the risk of the hook falling off and affecting the safety and reliability of lifting operations.
An anti-detachment component was designed, including an installation rod, a hook, a limiting groove, a lifting hook, a limiting hole, a blocking strip, a reset rod, a tension spring, a limiting rod, and a piercing rod. The reset rod is rotated by the torsion spring and engages with the blocking strip. The cooperation of the limiting groove and the limiting rod ensures that the hook is stably wound during lifting and avoids reset rod failure due to torsion spring failure.
It achieves a stable and anti-slip function for the hook, avoiding hook slippage due to torsion spring failure, and improving the safety and reliability of lifting equipment.

TECHNICAL FIELD
[0001] The utility model belongs to hoisting equipment technical field, concretely relates to a hoisting equipment with anti -drop hoisting hook. BACKGROUND
[0002] The anti-drop hoisting hook is a vital safety component in hoisting machinery, and its main function is to prevent the lifting hook from falling off or accidentally coming off during lifting, thereby ensuring the safety and reliability of the lifting operation.
[0003] The anti-drop component plays a vital role in hoisting machinery, and its main task is to ensure the stability of the lifting hook during operation and prevent safety accidents caused by the lifting hook slipping off. However, when the reset rod in the anti-drop component loses its function due to the failure of the torsion spring, the reliability of the entire anti-drop system will be severely threatened. Specifically, the reset rod is a key component in the anti-drop component, which is usually automatically reset by the elastic force of the torsion spring when the lifting hook is in a non-working state, ensuring that the lifting hook can accurately and stably enter the working state next time. However, if the torsion spring fails due to long-term use, wear or improper maintenance, the reset rod will not be able to reset normally. Once the reset rod fails, the consequences will be serious. First, the lifting hook may not be able to accurately enter the locking position of the anti-drop component when placed, leading to the lifting hook slipping off easily during lifting. Second, even if the lifting hook is locked, the locking force of the anti-drop component may be greatly reduced due to the incorrect reset of the reset rod, thereby increasing the risk of the lifting hook falling off.
