TECHNICAL FIELD

[0001] The utility model relates to portal crane steel wire rope supporting rope protection technical field, specifically disclose a portal crane steel wire rope supporting rope protection device. BACKGROUND

[0002] When the portal crane steel wire rope does not bear the tension, the steel wire is relatively fixed on the portal crane arm supporting rope device by overcoming the self weight of the steel wire rope, preventing the steel wire rope from retracting and causing the equipment damage. The original portal crane supporting rope device adopts 45# steel to make the steel wire rope supporting roller, and the steel wire rope supporting roller is often stuck and cannot rotate, resulting in rapid wear of the steel wire rope.

[0003] The specific reasons are as follows: because the steel wire rope adopts a hemp core self-lubricating steel wire rope, the lubricating grease squeezed out under the action of tension in the working process penetrates into the gap between the steel wire rope supporting roller and the steel wire rope supporting roller, causing the steel wire rope supporting roller to be stuck and unable to rotate, and causing direct wear of the steel wire rope and the steel supporting roller.

[0004] To solve the above problems, the patent with publication number CN116119561A discloses a crane balance beam steel wire rope supporting roller, which comprises a base, first vertical plates fixedly installed at the top of the base, and a second vertical plate fixedly installed at the middle of the top of the base; a lubricating assembly comprising a liquid storage block fixedly connected to the top of the base and used for lubricating the outer surface of the roller body; and an oil delivery assembly comprising an oil box fixedly connected to one side of the first vertical plate and used for delivering oil to the lubricating assembly.
