Abstract
The utility model relates to a steel wire rope for a high-speed elevator, comprising a central strand (or a hemp core), nine inner-layer strands and nine outer-layer strands, wherein the inner-layer strands wrap and twist the central strand (or a hemp core) symmetrically in a linear contact shape; and the outer-layer strands wrap and twist the outermost side of the steel wire rope symmetrically in a linear contact shape. As the steel wire rope is twisted by using the nine outer-layer strands to wrap and twist a central sub-rope (a metal core or a mixed metal core), the diameter uniformity of the steel wire rope is obviously improved compared with that of the steel wire rope with the hemp core; simultaneously the steel wire rope has better fatigue performance and lower extension; compared with that of eight strands of steel wire ropes, the reelability of the nine strands of steel wire ropes is better; and simultaneously, the steel wire rope has large contact surface with a traction wheel, has better wear resistance and is suitable for being used for a high-speed elevator.
Description
Technical field
The utility model relates to a kind of steel wire rope, specifically is meant the express elevator steel wire rope.
Background technology
More and more higher along with floor, the speed of elevator is also progressively promoting, the proportion that high-rise express elevator accounts in elevator is also rising year by year, because the speed of service of elevator is than higher, steel wire rope quality requirement to use is very high, particularly very high to the diameter poker uniformity and the requirement of fatigue life of steel wire rope.At present, elevator is in the majority with 8 * 19S+NE structure class steel wire rope with steel wire rope, this its rupture pull force coefficient of class steel wire rope national Specification has only 0.293, steel wire rope (being not more than 10mm) diameter range+2%～+ 6%, use ladder speed greater than the elevator of 2m/s on the life-span very short, fracture of wire, a disconnected burst phenomenon generally will appear in 2 years.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of ABRASION RESISTANCE, diameter poker uniformity and anti-fatigue performance all good express elevator steel wire ropes.
The technical scheme that solves the problems of the technologies described above is:
The express elevator steel wire rope comprises central strand, 9 internal layer thighs and 9 outer layer strand, described internal layer thigh symmetrically, be line and wrap the sth. made by twisting central strand touchingly, described outer layer strand symmetrically, be line and wrap sth. made by twisting touchingly in the steel wire rope outermost.
Further be improved to, described outer stock internal layer and skin are Xi Lushi; 9 finer wires of described internal layer symmetrically, be line and wrap the sth. made by twisting core wire touchingly; Described outer field 9 thick wires symmetrically, be line and wrap sth. made by twisting touchingly in the outer layer strand outermost.Described internal layer thigh be by 6 steel wires symmetrically, be line and wrap touchingly and twist with the fingers core wire and form.Described center stock internal layer and skin are Wa Lin and gulp down formula; 6 thick wires of described internal layer symmetrically, be line and wrap the sth. made by twisting core wire touchingly; Described skin comprises 6 thick wires and 6 finer wires, and wherein 6 thick wires are the recess that line embeds adjacent 2 steel wire of internal layer touchingly, and 6 finer wires are line and wrap the bossing of twisting with the fingers at 6 steel wire of internal layer touchingly respectively.
Substitute products as above-mentioned steel wire rope, another kind of express elevator steel wire rope, comprise hemp core, 9 internal layer thighs and 9 outer layer strand, described internal layer thigh symmetrically, be line and wrap the sth. made by twisting hemp core touchingly, described outer layer strand symmetrically, be line and wrap sth. made by twisting touchingly in the steel wire rope outermost.
Further be improved to, described outer stock internal layer and skin are Xi Lushi; 9 finer wires of described internal layer symmetrically, be line and wrap the sth. made by twisting core wire touchingly; Described outer field 9 thick wires symmetrically, be line and wrap sth. made by twisting touchingly in the outer layer strand outermost.Described internal layer thigh be by 6 steel wires symmetrically, be line and wrap touchingly and twist with the fingers core wire and form.
(form because center rope during steel wire rope is twisted with the fingers by 9 outer layer strand bags by internal layer thigh and central strand or hemp core, metal-cored or hybrid metal core) twisting forms, increased the contact area between steel wire rope and the traction sheave, each outer layer strand is to be the Xi Lushi twisting and to be formed by 9 thick wires, core wire of 9 finer wire bag sth. made by twisting simultaneously, outer 9 steel wires are thicker, make steel wire rope have good ABRASION RESISTANCE.
Because middle center rope (metal-cored or hybrid metal core) is to have 9 sub-threads (being the internal layer thigh) bag to twist with the fingers a central strand (or hemp core) twisting to form, its each sub-thread is to wrap the sth. made by twisting core wire symmetrically by 6 steel wires, has so just improved the uniformity of the rupture pull force and the rope footpath poker of steel wire rope greatly; Contrast 8 strand steel wire ropes, 9 strand steel wire rope reelabilitys can be good, simultaneously and the traction sheave contact-making surface big, have anti-wear performance preferably; 8 * 19S+NF steel wire rope of contrast same size, intensity, this structure breaking force of rope has improved 33% (the hybrid metal core improves 27%), diameter range requires+1%～+ 4%, in use the steel wire rope of this kind structure has stronger ABRASION RESISTANCE and fatigue resistance, and can reach more than 4 years service life.
