AI Technical Summary
The existing wire rope cores have wear problems during use, resulting in short service life and insufficient lubricating performance.
The composite wire rope core design is adopted, in which the center strand consists of polypropylene fiber wire and sisal wire. An oil storage tank is provided around the polypropylene fiber wire, and a thin steel wire is installed between the center strand and the dry hemp strand to improve the strength and lubricating performance of the rope core.
By increasing the design of the oil storage tank, the oil content and lubricating performance of the rope core are improved, the wear of the wire rope is reduced, the service life is extended, and the strength of the rope core is improved by the addition of thin steel wire.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel wire rope cores, in particular to a composite steel wire rope core. Background Art
[0002] The core of the steel wire rope used in elevators is made of natural fibers or synthetic fibers. For example, the core made of sisal fiber rope. The grease in the rope core is squeezed into the spaces between the steel wires in the strands for lubrication, which greatly reduces the internal wear between the steel wires. Therefore, increasing the oil content of the rope core can improve the lubricity of the steel wire rope. Utility Model Content
[0003] The technical problem to be solved by the present invention is to provide a composite steel wire rope core in view of the above-mentioned deficiencies in the prior art. To solve the above-mentioned technical problem, the technical solution adopted by the present invention is:
[0004] A composite steel wire rope core comprises a central strand, a plurality of dry hemp strands are twisted in a forward direction on the outer side of the central strand, the central strand comprises a polypropylene fiber line and a plurality of sisal lines, the sisal lines are twisted in a forward direction on the outer side of the polypropylene fiber line, and oil storage tanks are evenly distributed around the polypropylene fiber line.
[0005] Furthermore, the oil storage tank is an arc-shaped tank, and the opening of the oil storage tank is one third of the diameter of the arc.
[0006] Furthermore, a thin steel wire is arranged between the central strand and the dry hemp strand, and the dry hemp strand wraps and twists the thin steel wire around the outer side of the central strand.
[0007] Compared with the prior art, the composite steel wire rope core of the utility model has an oil storage tank around the polypropylene fiber line, which increases the oil content of the rope core, improves the lubrication performance of the steel wire rope during use, reduces wear and increases service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 2 It is a structural schematic diagram of the central strand of the utility model;
[0010] Among them, 1. center strand, 2. dry hemp strand, 3. acrylic fiber line, 4. sisal line, 5. oil storage tank, 6. fine steel wire. DETAILED DESCRIPTION
[0011] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.
[0012] like Figure 1 and Figure 2As shown, a composite steel wire rope core includes a central strand 1, twelve dry hemp strands 2 are twisted in a forward direction on the outer side of the central strand 1, the central strand 1 includes a polypropylene fiber line 3 and four sisal lines 4, the sisal lines 4 are twisted in a forward direction on the outer side of the polypropylene fiber line 3, and oil storage tanks 5 are evenly distributed around the polypropylene fiber line 3.
[0013] After the center strand is twisted, it is soaked with lubricating grease. In the present embodiment, the oil storage tank 5 is an arc-shaped tank, which can store more lubricating grease and improve the oil content. The opening of the oil storage tank 5 is one-third of the diameter of the arc, and the smaller opening can better lock the grease. When in use, the two ends of the rope core are sealed with resin glue to prevent leakage of lubricating grease. During the use of the steel wire rope, the internal polypropylene fiber line 3 is squeezed, and the lubricating grease slowly seeps out from the opening, thereby extending the service life of the steel wire rope.
[0014] A thin steel wire 6 is arranged between the central strand 1 and the dry hemp strand 2. The dry hemp strand 2 wraps and twists the thin steel wire 6 around the outer side of the central strand 1, and the thin steel wire is used to improve the strength of the entire rope core.
[0015] The present invention is not limited to the described embodiments. Those skilled in the art may make some modifications or changes without departing from the spirit and scope of the present invention, that is, within the scope of disclosure. Therefore, the scope of protection of the present invention shall be subject to the scope defined in the claims.
