Background technology
Elevator is in running, mainly be to rely on the friction of elevator ropes and traction sheave to come hoisting elevator, there is simultaneously 6-8 root traction steel-cable to promote suspended carriage, steel wire rope and traction sheave are in operation, because the diameter of steel wire rope is inhomogeneous, each root steel wire rope is inconsistent in instantaneous travel line speed, cause steel wire rope and traction sheave to produce relative sliding, cause the vibration of elevator, and the service life of having reduced steel wire rope and traction sheave, use the building of stair higher, the probability that accumulation produces relative sliding is higher, and vibration of elevator is more obvious.At present, elevator wire rope is take 8 strands of sisal cores as main, primary structure 8*19S+NF, and this class steel wire rope can't satisfy the user demand of high rise elevator.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of high rise elevator steel wire rope, the wirerope diameter good uniformity that adopts this preparation method to make, in running, the comfort level of elevator and stationarity are good, are suitable for the used elevator of skyscraper.The problem that exists to solve prior art elevator wire rope on the middle and senior level.
The objective of the invention is to be achieved through the following technical solutions:
A kind of preparation method of high rise elevator steel wire rope, it may further comprise the steps:
A selects wire rod: select center, internal layer and outer used steel wire;
B, a wire drawing: the wire rod of selecting is carried out preliminary drawing with wire drawing machine, obtain needed specification;
C, heat treatment: with the steel wire of primary drawing through heating, Quenching Treatment after, again surface treatment finally obtains the quenching steel wire of sorbitizing;
D, the secondary wire drawing: the quenching steel wire that above-mentioned heat treatment is obtained carries out drawing, and wire drawing is carried out alternating bending to steel wire after finishing;
E twists with the fingers thigh: the steel wire after the secondary wire drawing is pressed desired structure and the required outer layer strand of specification twisting steel wire rope and internal layer thigh, carry out alternating bending behind the one-tenth thigh, make strand wire;
F, center rope in the twisting: the internal layer thigh bag that 8 step e obtain is twisted with the fingers 3 bursts of hemp core twistings, make the middle center rope of steel wire rope;
J, torsade: the middle center rope of 8 outer layer strand bags of step e gained being twisted with the fingers step f gained, be twisted into required steel wire rope, in the twisting process, the tension force of every thigh is measured and controlled, make the Tension Difference of every thigh be no more than 3% tension force, and the rope of steel wire rope is directly measured and controlled, make the diameter tolerance of steel wire rope remain on the diameter of the steel wire rope of 2-4%, carry out alternating bending after becoming thigh, make steel wire rope.
Especially, center, steel wire of internal layer are selected the 70# Fine Steel Casting iron among the described step a, and outer silk is selected the 45-60# Fine Steel Casting iron.
Especially, all adopt 2 groups among described steps d and the step e, every group of 14 orthogonal assembly pulleys carry out alternating bending.
Especially, the hemp core among the described step f adopts the poly-third ethene wire rope core of right-laid.
Especially, the sth. made by twisting of middle center rope is to being right-laid among the described step f, and the lay pitch is the rope footpath of 5.7-6.1 middle center rope doubly.
Especially, through 2 groups, the orthogonal assembly pulley of every group of 7 pulleys carries out alternating bending after becoming among the described step j strand.
Beneficial effect of the present invention is, the preparation method of the described high rise elevator steel wire rope compared with prior art steel wire rope that makes of the inventive method can make the rope footpath allowance control of steel wire rope in the steel wire rope rope footpath of 2-4%, the dispersion of strand wire is controlled in 5% in every meter on the steel wire rope, be 8 outer layer strand of steel wire rope, in every meter length, the thigh deflection of every thigh is no more than 5% of 8 thigh average deformation amounts.By the wirerope diameter good uniformity of said method gained, in running, the comfort level of elevator and stationarity are good, are suitable for the used elevator of skyscraper.
The specific embodiment
Further specify technical scheme of the present invention below by the specific embodiment.
In the present embodiment, a kind of preparation method of high rise elevator steel wire rope, it may further comprise the steps:
Step 1, select wire rod: center, steel wire of internal layer are selected the 70# Fine Steel Casting iron, and outer silk is selected the 45-60# Fine Steel Casting iron;
Step 2, a wire drawing: the wire rod of selecting is carried out preliminary drawing with wire drawing machine, obtain needed specification;
Step 3, heat treatment: with the steel wire of primary drawing through heating, Quenching Treatment after, again surface treatment finally obtains the quenching steel wire of sorbitizing.
Step 4, the secondary wire drawing: the quenching steel wire that above-mentioned heat treatment is obtained carries out again drawing, adopts 2 groups after wire drawing finishes, and every group of 14 orthogonal assembly pulleys carry out alternating bending to steel wire;
Step 5, twist with the fingers thigh: the steel wire after the secondary wire drawing is pressed desired structure and the required outer layer strand of specification twisting steel wire rope and internal layer thigh, adopt 2 groups behind the one-tenth thigh, every group of 14 orthogonal assembly pulleys carry out alternating bending to rope strand, make strand wire;
