The invention discloses a sisal hemp core steel wire rope for a high-speed elevator, which comprises a sisal hemp core and an outer layer strand, wherein the outer layer strands wrap and are twisted on the outside of the sisal hemp core uniformly. The outer layer strands comprise 8 steel wire strands each of which has a seal type structure, a central steel wire is arranged in the middle of the outer layer strands, the inner layer of the outer layer strands consists of 9 thin steel wires which wrap and are twisted on the outside of the central steel wire uniformly, and the outer layer of the outer layer strands consist of 9 thick steel wires which wrap and are twisted on the outside of the inner layer uniformly. The invention also discloses a method for preparing the sisal hemp core steel wire rope for the high-speed elevator, which comprises: preparing the sisal hemp core, preparing the outer layer strands and combining to make the rope. The sisal hemp core steel wire rope for the high-speed elevator is uniform in diameter, high in torsion resistance and long in service life.
Description
Technical field
The present invention relates to and a kind of steel wire rope and preparation method thereof, relate in particular to a kind of high speed elevator with sisal hemp independent wire strand core wire rope and preparation method thereof.
Background technology
Increasingly high along with floor, the speed of elevator is also progressively promoting, and 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 using 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+NF structure class steel wire rope with steel wire rope; National Specification 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; And the anti-verticity of steel wire rope is relatively poor, percentage elongation is higher, causes less stable in use.The preparation steel wire rope adopts the mode of the oiling again of pooling capital earlier can't guarantee the steel wire sufficient lubrication in the prior art; The stress of steel wire rope per pass operation has been eliminated undesirable assurance not anti-verticity, common sisal hemp core diameter poker property difference has guaranteed not the diameter uniformity of steel cable.
Summary of the invention
The present invention is intended to overcome the deficiency of above prior art, provides even, the anti-verticity of a kind of diameter high speed elevator good, that percentage elongation is low to use the sisal hemp independent wire strand core wire rope.
Another object of the present invention provides the preparation method of a kind of high speed elevator with the sisal hemp independent wire strand core wire rope.
The following technical scheme of the employing that the present invention solves the problems of the technologies described above:
A kind of high speed elevator is used the sisal hemp independent wire strand core wire rope, comprises sisal hemp core and outer layer strand, and said outer layer strand is wrapped the outside of sth. made by twisting at the sisal hemp core equably.
Further, said outer layer strand comprises 8 strands of steel strands.
Further, the per share steel wire rope of said outer layer strand all is the Xi Lushi structure, and the center is 1 core wire, and internal layer is that evenly bag is twisted with the fingers 9 finer wires in the core wire outside, and skin is that evenly bag is twisted with the fingers 9 thick wires in the internal layer outside.
High speed elevator of the present invention may further comprise the steps with the preparation method of sisal hemp independent wire strand core wire rope:
(1) preparation of sisal hemp core: the dimity is processed the sisal hemp core through a strand system of twisting with the fingers simultaneously;
(2) preparation of outer layer strand: arranged steel wire through noseplate twisting with the fingers on strand car, drench oil after, produce desired structure through closing up mouthful to compress with the line ball punching block, eliminate the stress of thigh again through post-former, be received in then on the I-beam wheel, be prepared into outer layer strand;
(3) close rope: the outer layer strand bag is twisted with the fingers the sisal hemp core and on finished car, is arranged through noseplate; Through pre-former, compress through closing up mouth again, again behind the stress through post-former elimination thigh; On stretcher, carry out predraft, be received in then and be prepared into said steel wire rope on the I-beam wheel.
Beneficial effect of the present invention is embodied in the following aspects:
(1) because steel wire rope uses the sisal hemp core through the primary twisting moulding; Guaranteed the support degree of sisal hemp core; And the inhomogeneity raising in rope footpath there is certain help; The use of control that adds each strand tension force and back deformation technique, rope footpath can remain on+2% ~+4% scope in, contrast common elevator and be significantly improved with hemp center wireline.
(2) because said steel wire rope uses burst oily technology of pouring, can make grease be coated in the surface of every steel wire uniformly, penetrate into steel wire rope inside fully, improve the service life of steel wire rope, according to test data, steel wire rope can improve more than 20% service life.
(3) because said steel wire rope per pass production process is all used the back deformation technique, eliminated the inner stress of steel wire rope fully,, made the anti-verticity of steel wire rope improve 30% according to test data.
(4) because said steel wire rope through predraft technology, according to test data, can make the construction of wire rope percentage elongation descend more than 50%, explain that its resistance to elongation can be better, good stability.
