Description

Technical Field

[0001] The utility model relates to the technical field of steel smelting, in particular to a cable protection structure for a ladle covering device. Background Art

[0002] At present, the ladle cover device is usually installed on the vehicle frame. The structure can refer to the ladle cover device installed on the ladle car disclosed in Chinese invention patent CN114799139A. Usually, cables need to be set on the vehicle frame to connect various drive control components, but in the steel production process, molten iron is easy to overflow, especially under the blast furnace, resulting in a high probability that the molten iron will fall on the cable protection tube of the cover device. Since the cable protection tube is made of metal and is easy to conduct heat, the falling of molten iron will directly cause damage to the cable, affect the use of the cover device, and further affect steel production.

[0003] In the prior art, some protective measures have been adopted to prevent the molten iron from damaging the cable, such as adding a protective cover to the cable protection tube, placing foam material in the protection tube, etc. However, the effect of these protective measures in actual production is not ideal, because the protective cover may be damaged or displaced, and the foam material cannot completely isolate the temperature of the molten iron.

[0004] Therefore, there is no effective method in the prior art to solve the problem of cable damage caused by molten iron falling onto the cable protection tube of the covering device. Utility Model Content
