Abstract
A high-strength rope core of an elevator steel wire rope comprises a central strand and a composite strand which is wrapped and twisted outside the central strand in the forward direction, wherein the central strand is made of oil ramie yarn; the composite strand comprises four dry ramie yarns and four polypropylene fibers, and the dry ramie yarns and the polypropylene fibers are sequentially and uniformly arranged in an alternating manner; and a plurality of grooves are uniformly formed in the polypropylene fiber outer ring. Compared with the prior art, the utility model discloses an elevator wire rope high strength rope core adds synthetic fiber in natural fibre, improves the tensile strength of rope core, has seted up the breach moreover on polypropylene fiber, because dry ramie yarn surface is softer, when the twist, dry ramie yarn surface can be embedded into to the surperficial breach of polypropylene in, further promotes the intensity of rope core.
Description
Technical Field
The utility model relates to a wire rope technical field specifically indicates an elevator wire rope high strength rope core.
Background
The steel wire rope for an elevator is composed of strands and a core made of natural or synthetic fibers, and the core made of, for example, sisal has a high oil content and a good lubricating effect, but the tensile strength of the core is not as high as that of the core made of synthetic fibers.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to above-mentioned prior art not enough, and provide an elevator wire rope high strength rope core.
In order to solve the technical problem, the utility model discloses a technical scheme is:
a high-strength rope core of an elevator steel wire rope comprises a central strand and a composite strand which is wrapped and twisted outside the central strand in the forward direction, wherein the central strand is made of oil ramie yarn; the composite strand comprises four dry ramie yarns and four polypropylene fibers, and the dry ramie yarns and the polypropylene fibers are sequentially and uniformly arranged in an alternating manner; and a plurality of grooves are uniformly formed in the polypropylene fiber outer ring.
Further, the diameter of the central strand is 3.2 ± 0.1 mm.
Furthermore, the dry ramie yarn is formed by winding sisal fibers, and the surface of the dry ramie yarn is elastic.
Furthermore, the diameters of the dry ramie yarn and the polypropylene fiber are both 1.5 +/-0.1 mm.
Further, the groove is a trapezoidal opening or a square opening.
Compared with the prior art, the utility model discloses an elevator wire rope high strength rope core adds synthetic fiber in natural fibre, improves the tensile strength of rope core, has seted up the breach moreover on polypropylene fiber, because dry ramie yarn surface is softer, when the twist, dry ramie yarn surface can be embedded into to the surperficial breach of polypropylene in, further promotes the intensity of rope core.
