Problems solved by technology

Applying lubricating oil can reduce the wear of the wire rope, but the viscosity of the lubricating oil will increase the adhesion of the wire rope to small particles such as mud, sand, and gravel
When the wire rope with the above-mentioned foreign matter is in contact with the pulley and the reel, the wire rope will be squeezed by the foreign matter, which will damage the surface of the wire rope and shorten the service life of the wire rope

Abstract

The invention discloses a steel wire rope protector and engineering machinery. The steel wire rope protector comprises a supporting rod assembly and an idler wheel assembly. The supporting rod assembly comprises a first supporting rod and a second supporting rod. The idler wheel assembly comprises a first idler wheel, a second idler wheel, a first connecting shaft and a second connecting shaft. The first idler wheel is arranged outside the first connecting shaft in a rotating and sleeving mode, and the first connecting shaft is connected with the first supporting rod. The second idler wheel is arranged outside the second connecting shaft in a rotating and sleeving mode, and the second connecting shaft is connected with the second supporting rod. Brushes are arranged on the circumferential surface of the first idler wheel and the circumferential surface of the second idler wheel respectively. The steel wire rope protector can brush away foreign matter such as sand on the surface of a steel wire rope when the steel wire rope ascends or descends, and therefore the surface of the steel wire rope can be cleaned, the steel wire rope can be protected, and the service life of the steel wire rope can be prolonged.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a steel wire rope protection device and construction machinery. Background technique [0002] Steel wire rope is a flexible rope twisted with multiple or multiple thin steel wires, which plays the role of lifting, pulling, tensioning and bearing in material handling machinery. Steel wire rope has the advantages of high strength, light weight, stable operation, and is not easy to break suddenly. It is widely used in construction machinery such as rotary drilling rigs, cranes, and tower cranes. [0003] Steel wire ropes mostly play the role of lifting in construction machinery, such as the main winch wire rope of rotary drilling rig. As a lifting component, the steel wire rope needs to frequently go in and out of mud and sand during work, and also needs to shuttle between multiple fixed pulleys. In order to increase the service life of the steel wire rope, it is necessary to...
