Description
Technical field
The utility model relates to mine hoist equipment technical field, particularly a kind of gig grooving error on-line computing model.
Background technology
Gig is the throat equipment of shaft production, and in recent years along with the mining increase of the degree of depth and the expansion of scale, multi-rope friction hoisting machine is widely used; But the tension imbalance problem between many ropes is more outstanding, 2004 editions " metal and nonmetal mine safety code " 6.3.3.15 article clear stipulaties " between each steel rope, Tension Difference is no more than 10% ".Grooving diameter error is no more than 80 μm; Thereafter, 2010 editions " metal and nonmetal mine safety codes " modify to it, require that between grooving, diameter error is no more than 50 μm, but at present, the measurement technique generally used in industry is not but innovated, the method for measurement of steel wire plus depth chi, can not reach the survey precision that " code " requires, error between friction wheel each grooving is caused to transfinite, the equalization of strain between the steel rope directly having influence on high-speed cruising, because tension imbalance between restricting causes following harm more:
Because many ropes can not bear heavy duty simultaneously, hoisting cable two ends lifting container is caused to tilt, increase the load of central roller cage shoe, the steel rope that tension force is little simultaneously can present larger sth. made by twisting to power, make lifting container generation lateral deviation rotational force, cause the rolling cage shoe load of container both sides to become large thereupon, reduce its service life, increase gig operating load simultaneously, also virtually add lifting power consumption and maintenance cost.
Due to tension imbalance between restricting, the less steel rope of tension force is through main driving wheel, and steel rope play can occur in grooving, sends huge sound when situation is serious, causes indivedual Rope slot liner sharply to wear and tear, and causes " inverted engine " accident more.In addition, steel rope also can rotate while play in grooving, makes " undercut " phenomenon that steel rope and grooving edge occur in various degree, reduces friction coefficient while increasing grooving width, hides some dangers for for promoting safety.
Tension imbalance can make the less steel rope of tension force operationally produce significantly to shake, even collide, on the contrary, and wearing and tearing that the steel rope that tension force is large is too early and produce permanent fatigue; Single stressed excessive time, steel rope internal grease can be made to overflow surface, cause inner oleaginousness to reduce, accelerate to wear and tear between steel wire, significantly reduction steel rope tenure of use, very easily cause rope-broken accident.
In sum, the overbalance of multi-rope friction hoisting machine steel wire rope tension, endanger huge in lifting, how can measure the diameter error on reel between each grooving fast and accurately, avoid occurring that between many ropes, tension imbalance phenomenon is the technical barrier that lifting worker is badly in need of solving.
