The utility model has the effects that: compared with the prior common wire rope, the wire rope for rotary drilling rig has the advantages of excellent non-revolving performance and high anti-breakage tensile force; the wire rope adopting the multi-layer strand structure has flexibility and excellent performance, thereby being suitable for rotary drilling rig.
Description
Technical field
The utility model belongs to the steel wire rope technical field, and the particularly a kind of accurate Calculation and steel wire rope designed in conjunction of drawing of adopting specifically is a kind of rotary drilling rig steel wire rope 35W * 7-D28.
Background technology
In theory, the any structure steel wire rope, silk, a strand twisting coefficient under the corresponding lay pitch multiple situation arbitrarily all can carry out accurate Calculation, but calculating process is extremely loaded down with trivial details, must be to finding the solution calculating about the unary biquadratic equation of lay pitch multiple, and the traditional theory design-calculated is according to the hypothesis that is based on strand in rope, silk is in tight contact condition in thigh, and this hypothesis is a kind of perfect condition, both do not meet objective reality, do not met modern steel wire rope design philosophy yet.In practice, parameter designing to a kind of new construction steel wire rope, usually adopt the class ratio method, promptly utilize known twisting coefficient and steel wire diameter proportionate relationship to carry out the steel cord structure design, gained result's accuracy can't be predicted in design process and need could verify when producing.
The utility model content
The purpose of this utility model provides a kind of rotary drilling rig steel wire rope, be the rotary drilling rig usefulness steel wire rope 35W * 7-D28 that adopts accurate Calculation and the method design that combines of drawing, reach under the situation of controlling strand, thread gap the steel cord structure parameter is designed, guarantee design result smooth implementation in process of production.And reach to compare good not verticity, higher rupture pull force are arranged with ordinary steel rope; Adopt multilayer thigh structurally flexible good, be adapted at using on the rotary drilling rig.
The utility model adopts following method for designing to realize:
By known twisting coefficient (table 1) is carried out the mathematical regression analysis, can obtain any lay pitch multiple and twisting coefficient relational expression under certain burst of (silk) number situation
m＝3.262002×K
-0.03136
In the formula: m-twisting coefficient
K-lay pitch multiple
Thigh (silk) radical is 6 o'clock twisting coefficient tables 1
| K | 6.0 | 6.5 | 7.0 | 7.5 | 8.0 | 8.5 | 9.0 |
| m | 3.092 | 3.078 | 3.068 | 3.059 | 3.052 | 3.046 | 3.041 |
| K | 9.5 | 10.0 | 10.5 | 11.0 | 11.5 | 12.0 | |
| m | 3.037 | 3.033 | 3.030 | 3.027 | 3.025 | 3.023 |
Provide data and compare returning twisting coefficient value that relationship calculates and table 1 thus, worst error is 0.27%, can meet design requirement fully.
Can obtain lay pitch multiple and twisting coefficient relationship under other strand (silk) radical situation with quadrat method.
Owing to thigh presents elliptic jet at rope cross section and silk in the thigh cross section, transverse and minor axis (i.e. thigh or steel wire diameter) pass is simultaneously:
L＝D/COSα
In the formula: the L-transverse
D-ellipse short shaft (thigh or steel wire diameter)
The spiral angle of α-thigh or steel wire
In the design's method, introduce the long axis system number concept for convenient design, represent with c:
c＝L/D
Be c=1/COS α
The major axis coefficient can obtain by known spiral angle or calculating.
Can tentatively obtain outer layer strand (silk) diameter by the relationship that obtains.In the design, at first determine design rope footpath and strand cross section transverse, by drawing twisting state cross section is carried out with outer layer strand in design rope footpath afterwards and draw, and on sectional view, check and measure a burst gap; According to the gap width size outer layer strand diameter is adjusted, made gap width reach desirable control range.Adopt same quadrat method, can design the thigh structure.
Method for designing characteristics: 1, in design, introduce gap design thought and use concrete grammar that thigh (silk) gap is controlled; 2, in design, use strand (silk) actual oval cross section, make design accurately; 3, design in conjunction with drawing, simplified design is calculated, and design result is intuitively embodied; 4, make design result practical in process of production.
