Technical Field

The invention belongs to the technical field of steel wire ropes, and particularly relates to a steel wire rope with a waterproof wear-resistant fiber rope core.

Background

The steel wire rope has a plurality of steel wire rope products, is widely applied in the current production and life, and the service life of the steel wire rope directly influences the efficiency and safety of the production and life. The rope core is the central part of the steel wire rope, is an important component of the steel wire rope, is generally divided into a metal core and a fiber rope core, mainly plays a role in supporting and reducing pressure between strands, and can also play a role in oil storage and lubrication. For some trial working conditions of mine hoisting, ocean towing or more severe environments, the steel wire rope is in severe environments such as high humidity, acid-base corrosion, seawater erosion and the like for a long time, and abrasion and corrosion are easily caused due to friction and abrasion among strands and among rope pulleys in the using process, so that the service life of the steel wire rope is greatly influenced. Therefore, how to better protect the fiber rope core, improve the strength of the fiber rope core, enable the fiber rope core to be better waterproof and anticorrosive and improve the wear resistance becomes a key problem.

Disclosure of Invention

In view of the above disadvantages, the present invention provides a steel wire rope having a waterproof and wear-resistant fiber core, wherein the fiber core has high strength and high waterproof and wear-resistant properties, and can improve the compactness among strands and reduce the friction among strands, thereby prolonging the service life of the core and the whole steel wire rope.

The invention has the technical content that the steel wire rope with the waterproof wear-resistant fiber rope core comprises the fiber rope core and an outer layer rope strand, wherein the outer layer rope strand is arranged on the outer side of the fiber rope core; it is characterized in that a waterproof layer and a wear-resistant layer are sequentially arranged on the fiber rope core from inside to outside.

In the steel wire rope with the waterproof wear-resistant fiber rope core, the waterproof layer is made of PP, PE or PU functional plastics; the water-proof layer is preferably thermoplastic polyurethane elastomer (TPU); the waterproof layer is coated on the fiber rope core by adopting a conventional padding process, and the thickness of the waterproof layer is 0.1-0.25 mm; polyurethane is coated on the surface and in gaps of the fiber rope core through a padding process, and then the fiber rope core is formed into a film shape in a pre-baking oven, so that the surface state of the fiber rope core is changed, the surface of the fiber rope core is smooth, the surface tension is reduced, and the fiber rope core is endowed with good water resistance and oil repellency; the elongation of the polyurethane film is far greater than that of the rope core, so that the coating film of the waterproof layer keeps a good state and does not generate faults in use.

In the steel wire rope with the waterproof wear-resistant fiber rope core, the wear-resistant layer is made of PA plastic material, preferably PA6, PA12, PA66 or PA1010 plastic, is arranged on the waterproof layer of the fiber rope core through an extrusion molding process, and is annular and 0.3-0.5 mm in thickness; in order to further enable the fiber rope core and the outer layer rope strands to be compact in structure when the rope is combined, a plurality of spiral grooves corresponding to the outer layer rope strands are formed in the outer surface of the wear-resistant layer.

In the above-mentioned steel cord having a waterproof and abrasion-resistant fiber core, the fiber core may be a natural fiber core or a synthetic fiber core, including any of various materials such as sisal, jute, abaca, synthetic fibers PP, PVC, PE, high molecular modulus PVC, high density PE, etc., and fiber cores both suitable for steel cords; covers the wire core related to various current fiber core wire rope standards.

Compared with the prior art, the invention has the advantages that the fiber rope core is not exposed any more but closed, thus reducing the corrosion of external environment such as water vapor, acid and alkali to the rope core; secondly, the fiber rope core is not directly contacted with the outer layer strand any more, so that the abrasion of the outer layer steel wire to the fiber rope core is reduced, and the service life of the fiber rope core is prolonged; meanwhile, due to the existence of the wear-resistant layer, gaps among the strands are filled, and the strength of the rope core is indirectly improved.
