Description

Technical Field

[0001] The utility model relates to a hoisting system for charging a blast furnace, in particular to an automatic cleaning and lubricating device for a hoisting steel wire rope. Background Art

[0002] The loading of blast furnace is realized by the winch system, which is driven by two motors. After being decelerated by the reducer, the winch drum is driven to rotate. The steel wire rope on the drum is used to pull the material cart alternately and cyclically through the fixed sheave group to transport raw materials from the bottom of the trough to the top of the blast furnace.

[0003] Through the analysis of the equipment operation status of the blast furnace charging winch system, we found that the main problem affecting the equipment operation rate is the wear of the winch wire rope. The wire rope is replaced twice a year, and there is room for cost reduction and improvement.

[0004] The wear of wire rope is reflected in:

[0005] The surface of the wire rope is not lubricated enough because the manual oiling method is used, which results in uneven lubrication and irregular timing, making it difficult to meet the lubrication needs of the wire rope.

[0006] The internal lubrication is insufficient. The reason is that the oil and dust on the surface of the wire rope are difficult to remove manually, and the lubricating grease is difficult to penetrate into the inside of the wire rope, resulting in a lack of lubrication inside the wire rope. Summary of the invention

[0007] The utility model aims at the problems existing in the prior art and proposes an automatic cleaning and lubricating device for a winch wire rope, which automatically cleans the wire rope through a wire brush roller and atomizes the wire rope through an oil spraying transverse pipe and compressed air, thereby slowing down the deterioration rate of the winch wire rope such as wear and breakage, and prolonging the service life of the material car wire rope.
