Description

Novel compacted strand steel wire rope

Technical Field

The utility model belongs to the technical field of the wire rope technique and specifically relates to a novel compaction thigh wire rope.

Background

The steel wire rope is a metal product with wide application, and is often used in the fields of lifting, traction, tensioning, bearing and the like of various devices, in the currently used steel wire rope, because steel wires are generally in a linear contact state, the internal structure of the steel wire rope is loose, and the steel wire rope is easy to rotate under the action of stress in the actual use process, so that the abrasion of the steel wire rope is aggravated, and the service life of the steel wire rope is shortened.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a compact structure, stability is strong, anti punching press ability and anti bending capability are strong novel compaction thigh wire rope.

The utility model discloses a realize through following technical scheme:

the utility model provides a novel compacted strand wire rope, includes central thigh, covering strand, packing strand and outer layer strand, its characterized in that: the wrapping strand is wrapped and twisted with the central strand, the filling strand is positioned in a concave part embedded into two adjacent wrapping strands in a linear contact manner, the central strand, the wrapping strands and the outer strands are twisted alternately, and fiber yarns are filled between the wrapping strands and the outer strands.

And the central filaments and the outer filaments of the central strand, the cladding strand, the filling strand and the outer strand are all in surface contact.

The number of the central strands was 1, the number of the clad strands was 4, the number of the filler strands was 4, and the number of the outer layer strands was 14.

And the lay length of the steel wire rope is 6 times of the diameter of the steel wire rope, and the lay length of the inner layer sub-rope is 5.5 times of the diameter of the inner layer sub-rope.

And the central strand and the cladding strand are respectively formed by twisting 1 central filament and 8 outer layer filaments.

Furthermore, the filling strand is twisted from 1 central filament and 6 outer filaments.

Also, the outer layer strands are twisted from 1 central filament and 6 outer layer filaments.

The utility model has the advantages that:

in the utility model, the wrapping strand twisting central strand increases the sectional area of the inner layer rope and improves the breaking force; each strand adopts an interactive twisting mode, so that the steel wire rope has the characteristic of no rotation; because each strand of the steel wire rope is a compacted strand, the steel wire rope has low internal oil content, is lack of lubrication and easy to rust, and has the problem of wire breakage due to increased friction between steel wires, fiber wires are filled between the cladding strand and the outer layer strand, the oil content of the steel wire rope is increased, the wear resistance of the steel wire rope is improved, and the flexibility of the steel wire rope is also improved; each strand adopts a surface contact mode, so that the contact stress among the strands is reduced; the arrangement proportion of the central wire and the outer wire of each strand is more suitable for rolling processing; the lay length is shortened, the gaps among strands are reduced, the stability of the steel wire rope is improved, and the fatigue life of the steel wire rope is prolonged.

Detailed Description

The present invention is described in detail below with reference to examples, which are illustrative and not restrictive, and the scope of the invention is not limited thereto.

The utility model provides a novel compacted strand wire rope, includes central thigh 5, and covering strand 4 fills thigh 2 and outer thigh 1, the utility model discloses an innovation lies in, covering strand package twists with fingers central thigh, fills the thigh and is located the depressed part that is two adjacent covering strands of linear contact form embedding, central thigh, covering strand and outer thigh adopt mutual system of twisting with fingers, and it has cellosilk 3 to fill between covering strand and the outer strand.

In this embodiment, the fiber filaments may be made of sisal core or other materials, such as nylon, polypropylene, etc.

In this embodiment, in order to increase the specific surface area and increase the oil storage capacity of the fiber, the fiber may adopt a mesh structure.

In this embodiment, the central filaments and the outer filaments of the central strand, the cladding strand, the filling strand and the outer strand are all in surface contact.

In this embodiment, the central strand is 1, the cladding strand is 4, the filling strand is 4, and the outer layer strand is 14.

In this embodiment, the lay length of the steel wire rope is 6 times of the diameter of the steel wire rope, and the lay length of the inner layer sub-rope is 5.5 times of the diameter of the inner layer sub-rope.

In this embodiment, the central strand and the cladding strand are formed by twisting 1 central filament and 8 outer filaments.

In this embodiment, the filling strand is formed by twisting 1 central filament and 6 outer filaments.

In this embodiment, the outer layer strands are formed by twisting 1 central filament and 6 outer layer filaments.
