Description

Technical Field

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

[0002] Anode carbon block refers to a carbon block produced with petroleum coke and asphalt coke as aggregate and coal tar as binder, and is used as anode material for prebaked aluminum electrolytic cell. This carbon block has been baked and has a stable geometric shape, so it is also called prebaked anode carbon block, and is also customarily called carbon anode for aluminum electrolysis. In the production process of anode carbon blocks, a crane is usually required to lift the anode carbon blocks for moving and stacking. At present, there are many lifting slings for anode carbon blocks, such as: an anode carbon block clamp disclosed in Chinese patent CN220165617U, an anode carbon block lifting sling disclosed in Chinese patent CN215287687U, etc. However, these anode carbon block slings still have some defects, such as: the angle of the clamping surface of the clamping arm of the sling in contact with the anode carbon block cannot be adjusted; the distance between the two clamping arms cannot be adjusted, etc., which makes the sling adaptable and difficult to apply to anode carbon blocks of different specifications.

[0003] In order to solve the above problems, people have been seeking an ideal technical solution. Utility Model Content

Then, the sling clamp is driven by the first hydraulic cylinder to swing inward to clamp the anode carbon block. Since the clamping plate and the sling clamp are hinged, a certain angle can be fine-tuned. In the clamped state, the clamping plate can fit the side wall of the anode carbon block.

[0023] In one embodiment, the sling beam 1 includes an upper beam 104 and a lower beam 101, and the upper beam 104 and the lower beam 101 are connected by a vertical hanger 102.

[0025] In one embodiment, the two second hydraulic cylinders 6 are connected by two sets of connecting plates, and a gap is left between the two sets of connecting plates. The part of the first hydraulic cylinder 5 located in the inner cavity of the lower cross beam 101 is arranged through the gap, which facilitates the vertical arrangement of the first hydraulic cylinder and the second hydraulic cylinder.
