Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to an automatic balancing hook device for a universal bridge crane. Background Art

[0002] Silicon metal, also known as industrial silicon or crystalline silicon, is a silver-gray material with a metallic luster and is available in both block and powder form. Its primary component, silicon, accounts for approximately 98%, with the remaining impurities being iron, aluminum, and calcium. During its production and processing, lifting equipment is required to transport it between various steps.

[0003] The existing Chinese patent with authorization announcement number CN220376164U discloses a lifting device for metallic silicon material with a protective mechanism, including a moving component, a hoisting component, a hoisting component, an anti-falling component, a hoisting rope and a hopper, wherein: the moving component is used to transfer the block metallic silicon in the hopper; the utility model uses the moving component, the hoisting component and the hoisting component in combination, so that the hopper containing the block metallic silicon material can be hung on the hook at the bottom end of the hoisting rope through a lifting ring, and the hopper is lifted by the hoisting component, and then the position of the hopper can be moved by the moving component. The setting of the anti-falling component can limit the lifting ring on the hook to prevent the lifting ring from falling off the hook. The setting of the anti-falling component can prevent the block metallic silicon from falling from the hopper due to shaking during the lifting process. The block metallic silicon will fall into the inner cavity of the fixed shell to prevent the block metallic silicon from falling due to shaking and hitting the operator's feet.

[0004] The disadvantages of the above-mentioned existing technical solution are that ton bags are used for shipping metallic silicon, and multiple hanging straps are usually provided around the opening of the ton bag. The above-mentioned device is only provided with one hanging hook, which makes it inconvenient to adjust the balance of the ton bag when lifting it. Utility Model Content
