Description

Technical Field

[0001] The utility model relates to a lifting clamp, in particular to an anti-falling anode carbon block lifting clamp. Background Art

[0002] Anode carbon blocks refer to carbon blocks that are made of petroleum coke and asphalt coke as aggregates and coal tar as binder, have been roasted, and have a stable geometric shape. They are used as anode materials for pre-baked aluminum electrolytic cells. In the production process of anode carbon blocks, it is usually necessary to move the anode carbon blocks by crane. At present, most cranes use clamps and hoists to clamp anode carbon blocks. For example, Chinese patent CN119660544A discloses an anode carbon block loading and unloading device. However, the use of clamps to clamp anode carbon blocks depends entirely on the friction between the clamps and the anode carbon blocks after inflation. During the application process, debris in the environment can easily affect the stability of inflation and clamping.
