Two cover three locks knot and knotting method
Technical field
The present invention relates to two cover three lock knot and knotting method, belong to knot technical field.
Technical background
Rope tool is that the mankind contact and one of the instrument that uses the earliest, and for thousands of years, people, in use rope tool process, have invented a lot of knot technology, served the mankind.
Along with the continuous progress of mankind's science and technology, today, the mankind have entered into the great development epoch of height industrial civilization, modern mechanical technology needs and employs a large amount of new metallic cable tools: iron wire, steel cable etc., they have intensity, the super large elasticity and hardness etc. of superelevation, traditional knot technology is for them, can not be suitable for completely, because their hardness, elasticity orders about ability far beyond artificial hand-power, so from metallic cable tool is born, people even just do not expect will by knot Technology application in these industry rope tools.
In recent years, along with the technological progress of industrial machine, people start the feature according to these new rope materials, utilize industrial machine to process pointedly, start few use amount knot technology, serve industrial production, such as iron wire binding have employed the knot such as reef knot and the sheet bend technology, but compared in more conglomerate utilize thicker stronger modern industry rope tool, such as trip's tourist coach, the exploitation of glory-hole industry, large-scale field bridge building operations etc., also substantially uselessly at present arrive knot technology.
Summary of the invention
For resolving the problems referred to above, the invention provides a kind of two cover three lock knot and knotting method, specially for the knot technology of the feature design invention of modern industry rope tool, the craft knotting that it is not only applicable to traditional fibre class rope tool utilizes, can be more high strength, high hardness, elastomeric metallic cable tool utilized, we can utilize the mechanical force of machine, two cover three is locked knot Technology application in the manufacturing industry of steel rope ring and chain rope, produce the industry rope tool product of plurality of specifications and different demand, for the mankind carry out the accurate power transmission service of large load, very-long-range.
Steel rope ring is current common industry rope tool, for hoisting and hanging and the chain rope drive parts that may occur.
Chain rope drive has very-long-range, carries greatly, accurate without smooth, without polygon effect, close to plurality of advantages such as zero partial twist squares, the 4th kind of accurate kind of drive after gear, chain, toothed belt, knot locked by two cover three and the normal tight knot of derivative three cover three locks has firm, the reliable and stable characteristic of fabulous locking, can be industrial chain rope and manufactures used.
The form of two cover triangle chain of rings locking Anti-rope drop knot is two lassos, locking N-Side surf is that triangular form three triangle of restricting presses linkage structure mutually, locking firm stable, solves and uses Portuguese bowline or rolling hitch once occur that power is lost in one end or the rotatable rope stretching of loop bar saves lock-off distortion, even collapses defect and the problem of inefficacy.
The knotting method of knot locked by two cover three: first beat single knot, two cover three lock knot is got again on unijunction basis, particularly, make a call to a unstrained single knot, loop bar is inserted unijunction along one end rope yarn equality, reserve a little loop bar termination, push down side, outer end rope yarn on loop bar, another rope yarn is surrounded forward from the back side and firmly inserts loop bar, what judge this rope yarn curls up direction, outwards another fake is upwards pulled out again in loop bar side dorsad, direction rotating Vortex fake 180 ° is curled up with judged before, and then turn back 180 ° fake to be returned wear along loop bar termination and hang on loop bar, tension, be shaped to two covers three lock knot of aesthetic criteria.
Two cover three is locked knot and can be derived three covers three and lock normal tight knot, also can be called three covers three and lock consolidation forever, it is based on the method for beating two cover three lock knot, how all another end is many around one week or, the normal tight joint of knot locked by derivative three covers and above three of getting, its locking quality is more firm stable, and under normality, its certain safety factor is 100%.
Example is become to make three cover three locks, its knotting method is: first make a call to a unstrained single knot, by loop bar along the parallel insertion unijunction of one end rope yarn, reserve a little loop bar termination, push down side, outer end rope yarn on loop bar, another rope yarn is surrounded forward from the back side and firmly inserts loop bar, again alone around loop bar 360 °, and judge this rope yarn curl up direction, outwards another fake is upwards pulled out again in loop bar side dorsad, direction rotating Vortex fake 180 ° is curled up with judged before, and then turn back 180 ° fake to be returned wear along loop bar termination and hang on loop bar, tension, be shaped to three covers and the normal tight joint of above three lock knots of aesthetic criteria.
The application of knot and knotting method thereof locked by two cover three: two cover three lock knot and three covers three that derive lock the knotting that normal tight knot can be widely used in traditional rope yarn, also can be used for the machine knotting of wire rope, manufacture processes the parts product such as Industrial Steels becket bridle, chain rope, its medium chain rope product will be widely used in the power transmission of suspension type warehouse system, the power transmission system in the fields such as safe and efficient energy-conserving elevator, trip's tourist coach, large-scale field construction and outdoor mining activities.

Include in above-mentioned figure: rope yarn 1, loop bar 2, knot 3 locked by two cover three, three cover three lock knots 4, steel loop connection set 5, steel collar 6, cover rod tube 7, screw locking device 8.
Be further described below by way of embodiment:
Embodiment one: the knotting method of knot 3 locked by two covers three.
See Fig. 1.
Fig. 1 is the knotting evolutionary process schematic diagram of two cover three lock knot 3.
First beat unijunction, two cover three lock knot 3 is got again on unijunction basis, particularly, rope yarn 1 is first used to make a call to a unstrained single knot, by loop bar 2 along the parallel insertion unijunction of one end rope yarn, reserve a little loop bar 2 termination, push down side, outer end rope yarn 1 on loop bar 2, another rope yarn 1 is surrounded forward from the back side and inserts loop bar 2, what judge this rope yarn curls up direction, outwards another fake is upwards pulled out again in loop bar 2 side dorsad, direction rotating Vortex fake 180 ° is curled up with judged before, and then turn back 180 ° along loop bar 2 termination, fake to be returned to wear and hang on loop bar, tension, be shaped to two covers three lock knot 3 of aesthetic criteria.
Embodiment two: the knotting method of derivative three cover three lock knots 4.
See Fig. 2.
Fig. 2 is the knotting evolutionary process schematic diagram that knot 4 locked by three covers three.
Rope yarn 1 is first used to make a call to a unstrained single knot, by loop bar 2 along the parallel insertion unijunction of one end rope yarn, reserve a little loop bar 2 termination, push down side, outer end rope yarn 1 on loop bar 2, another rope yarn 1 is surrounded forward from the back side and inserts loop bar 2, again alone around loop bar 2 around 360 °, and judge this rope yarn 1 curl up direction, outwards another fake is upwards pulled out again in loop bar 2 side dorsad, direction rotating Vortex fake 180 ° is curled up with judged before, and then turn back 180 ° along loop bar 2 termination, fake to be returned to wear and hang on loop bar, tension, be shaped to three covers and the normal tight joint 4 of above three lock knots of aesthetic criteria.
Embodiment three: adopt three cover three lock knots 4 to manufacture steel rope ring.
See Fig. 3, Fig. 4.
Fig. 3 is a steel rope ring schematic diagram, and it is manufactured process and is: on steel collar 6, cover rod tube 7, gets one the three normal tight joint 4 of lock knot respectively, and then with screw locking device 8 by steel collar 6, overlap rod tube 7 and be socketed and lock.
