Description

Steel wire rope

Technical field

The utility model relates to building and engineering material, particularly steel wire rope.

Background technology

Steel wire rope is the very large a kind of consumable material of use amount in producing, living.Directly influence the efficient and the safety of production, life the service life of steel wire rope.The steel wire rope that common process is twisted with the fingers system shows not wear-resisting performance under conditions such as vertical shaft hoisting, in the use therefore the phenomenon of fracture of wire in advance can be arranged more, and fracture of wire quantity transfinites and then need scrap.

Also there is structural unstable defective in the conventional structure steel wire rope.Rope strand is circular, and tangent to each other between the rope strand, the space between the rope strand is bigger, has gravitation and friction inevitably between the steel wire of internal layer rope, has reduced the compactedness between each strand, has influenced the life-span of steel wire rope greatly.

The conventional structure steel wire rope receives the restriction of equipment volume and Wire Rope Production factor, receives existing producing technique of steel cable restriction again.Therefore, have to strengthen the diameter of steel wire rope, or improve the tensile strength of steel wire rope.Parallel sth. made by twisting forge wire rope of the prior art, steel cable is loose, and whole rope rupture pull force is not enough.

The utility model content

The purpose of the utility model is to provide a kind of novel steel wire rope.

To achieve these goals, the steel wire rope that the utility model provides comprises: steel wire rope, comprise outer layer strands and the internal layer rope strand that coats by outer layer strands, and contact for face closely between outer layer strands and the internal layer rope strand.

In some embodiments, outer layer strands is 16 strands, per sharely is made up of 7 steel wires.

In some embodiments, the internal layer rope strand is 19 strands, per sharely is made up of 7 steel wires.

In some embodiments, 19 strands of internal layer rope strand ecto-entads are respectively 12 strands, 6 strands and 1 strand.

In some embodiments, it is characterized in that the outer layer strands cross section is fan-shaped.

According to the utility model; The rupture pull force of steel wire rope has been improved more than 20% on the basis of general steel wire rope; Increase the tensile strength of steel wire rope, prolonged the service life of steel wire rope, eliminated gravitation and friction between the internal layer rope strand simultaneously; Increased the compactedness between each rope strand, made steel wire rope tightr, wear-resisting.

The specific embodiment

Come the utility model is done further to describe in detail explanation below in conjunction with accompanying drawing and specific embodiment.

As depicted in figs. 1 and 2, steel wire rope comprises some strand, and rope strand is formed by some steel wire twisteds.Rope strand comprises outer layer strands 1 and the internal layer rope strand 2 that is coated by outer layer strands 1.In one embodiment, outer layer strands 1 is 16 strands, and internal layer rope strand 2 is 19 strands.The distribution ecto-entad of 19 strands of internal layer rope strands 2 is respectively 12 strands, 6 strands and 1 strand.

Like Fig. 3 and shown in Figure 4.Per share rope strand is formed by 7 steel wire 3 compactings, and internal layer rope strand 2 forges after compacting when twisted with outer layer strands 1.Through adopting such scheme, the rupture pull force of steel wire rope has been improved more than 20% on the basis of general steel wire rope, increased the tensile strength of steel wire rope, prolonged the service life of steel wire rope.

Steel wire rope forges after compacting in the process of twisted, makes the steel wire distortion, and it is big that the abutted surface between steel wire and the steel wire becomes, gap smaller.The outer layer strands cross section is fan-shaped, and internal layer rope strand cross section is irregularly shaped.For face contact closely, increased the compactedness between each rope strand between each rope strand, made steel wire rope tightr, wear-resisting.Simultaneously, eliminate gravitation and friction between the internal layer rope strand, improved the rotatory of steel wire rope in the course of work, be difficult for distortion, prolonged the service life of steel wire rope.

The per share finer wire of outer layer strands 1, internal layer rope strand 2 directly is twisted into face contact rope strand through the twisted machine, and rope strand is again through forging the formation steel wire rope.

Fig. 5 has schematically shown the longitudinal section that forges the mould in the process according to the steel wire rope of the utility model.Mould is strip, and the longitudinal section of lower ending opening is semicircle.When forging; In mould openings, put into pad; To wait that again the steel wire rope of beating puts into mould openings; The X common swager of series (X30 type and X50 type) that uses Chuangxin Precision Instrument Inst., Xian to produce forges steel wire rope, causes wirerope diameter, reduced cross-sectional area, and the silk in the rope is with burst distortion so that produce an opposed flattened and wear-resisting surface.The steel wire rope smooth surface, breaking load increases.

In sum, the utility model forges twisted with steel wire rope through 35 strand compactings and forms, outer 16 strands; 19 strands of internal layers, and per sharely form by 7 steel wire compactings, the rupture pull force of steel wire rope has been improved more than 20% on the basis of general steel wire rope; Increase the tensile strength of steel wire rope, eliminated gravitation and friction between the internal layer rope strand simultaneously, increased the compactedness between each rope strand; Make steel wire rope tightr, wear-resisting, improved the life cycle of steel wire rope.This steel wire rope can be widely used in equipment such as vertical shaft hoisting, large-scale lifting salvaging and the tower lifting in harbour, and effect is obvious.

The utlity model has the characteristics that tight, wear-resisting, disconnected broken pulling force is big, be difficult for distortion, have good economic benefit and social benefit.

Above-described only is the optimal way of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement, these also should be regarded as within the protection domain of the utility model.
