Description

A wire rope safety anti-detachment device

Technical field:

The utility model relates to an improvement in the structure of a steel wire rope anti-detachment device for an aluminum electrolysis multifunctional crane for lifting aluminum.

Background technique:

In the aluminum lifting device of the electrolysis multifunctional crane, the steel wire rope is usually used to wind the movable pulley as the intermediate lifting mechanism of the power transmission. There are potential safety hazards in the production process of this structure. In the process of aluminum tapping and sporadic lifting, when the hook is lowered to a certain position, the steel wire rope will inevitably slack. When the steel wire rope is slack, due to its own elastic effect, the steel wire rope is separated from the correct position of the moving pulley rope groove, commonly known as "job jumping". If this phenomenon cannot be eliminated in time, when the hoisting device is restarted, it will inevitably cause jamming or tilting of the lifting object, resulting in serious consequences.

Utility model content:

The utility model aims at the problems mentioned above and provides a safety anti-off device for steel wire ropes with simple structure and convenient disassembly.

In order to achieve the above object, the utility model adopts the following technical scheme, the utility model comprises a pulley shaft, the pulley shaft is provided with an inner pulley and an outer pulley, and the bottom and sides of the outer pulley are respectively provided with webs and side plates, The side plate is fixed on the yoke plate of the pulley shaft; the bottom and side of the inner pulley are respectively provided with a web and a side plate, and the side plate is fixed on the yoke plate of the pulley shaft.

The beneficial effects of the utility model:

The utility model has the advantages of simple structure and convenient disassembly, which can effectively prevent the steel wire rope from falling out of the groove and play a very good role in safety guarantee.
