Abstract
The utility model provides multilayer strand compacting strand steel wire rope hinge rigging, which is formed by an annular steel wire rope, and a compacting strand steel wire rope is selected for the steel wire rope. The steel wire rope comprises a central strand, internal layer strands, secondary external layer strands, and external layer strands, each strand in the steel wire rope is formed by six external layer steel wires wrapping a center steel wire. Since a surface-contact shape is provided between steel wires in each strand of the steel wire rope, and the steel wire rope is formed by three strands wrapping and twisting one center strand, the steel wire rope is advantaged by good anti-rotation performance, high breaking force coefficient, and stronger wear resistance, anti-extruding performance, and impact load resistance performances. Also, since the strength of steel wire rope casting rigging is the same as the strength of the used steel wire rope, compared with common casting rigging, the bearing capacity can be improved by nearly 26.1%, and therefore the whole steel wire rope rigging is provided with higher bearing capacity and long service lifetime.
Description
Technical field
The utility model relates to a kind of rigging, particularly, relates to the hinged rigging of a kind of multilayer strand compacting thigh steel cable.
Background technology
Rigging is as every field such as manufactured consumer goods are widely used in making, ship, and along with the requirement of the personalized Conceptional Design of Main Girder Erection in each high-end field becomes increasingly conspicuous, market is also more and more higher to the requirement of rope rig.At present, the common rigging most of 35W of employing of steel wire rope * 7 circle thighs are serial, and its rupture pull force coefficient is 0.36, and strength grade is 1770MPA, low bearing capacity, and service life is short.
The utility model content
The purpose of this utility model is for defects of the prior art, proposes the hinged rigging of multilayer strand compacting thigh steel cable that a kind of rupture pull force coefficient is high, anti-wear performance is good.
The technical scheme that realizes above-mentioned purpose is as follows:
The hinged rigging of a kind of multilayer strand compacting thigh steel cable is made of annular wire rope, and steel wire rope adopts compaction-strand steel wire rope.
Further, described steel wire rope is to twist with the fingers the total head real shares steel wire rope that the central strand twisting forms by three layers of thigh bag, per share by core wire composition of 6 cover wire bags sth. made by twisting in the described steel wire rope, described cover wire approximate trapezoid, described core wire is similar to regular hexagon, is face between the per share interior steel wire of described steel wire rope and steel wire and contacts shape.
Further, described three layers of thigh comprise 16 of 6 on internal layer thigh, 12 of inferior outer layer strand and outer layer strand.
Further, described 12 outer layer strand comprise 6 thick strand and 6 thin strand.
The utlity model has following beneficial effect:
1, the mode of production of utilizing die drawing is carried out (cold-)drawn (steel)wire rope rope strand with mould when twisting with the fingers burst, wire shape in changing strand but substantially do not change the cross-sectional area of steel wire makes to be face between steel wire and steel wire in the rope strand and to contact shape, then closes rope again.Because the structure of rope strand is face contact shape through the mould extruding, has improved steel wire rope metal effective area, anti-wear performance is good in use.
2, the steel wire rope of this kind structure is formed by central strand twisting of three layers of thigh bags sth. made by twisting, rigging does not rotate under the state that does not carry, its resistance rotation performance is good, have stronger crush resistance and resistance to shock loads performance, bearing capacity of the present utility model has improved 26.1% on the basis of common compacting rigging, the rupture pull force coefficient reaches 0.41, and strength grade reaches 1960MPA, long service life.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and consists of the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not consist of restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the schematic diagram of the hinged rigging of a kind of multilayer strand compacting of the utility model thigh steel cable.
Fig. 2 is the cross section structure schematic diagram of steel wire rope on the hinged rigging of a kind of multilayer strand compacting of the utility model thigh steel cable;
By reference to the accompanying drawings, Reference numeral is as follows among the utility model embodiment:
Mark is illustrated as among Fig. 1-2,1 rigging, 2 central strand, 3 internal layer thighs, thick strand of thin strand, 5 times skins of 4 skins, 6 outer layer strand.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the hinged rigging 1 of a kind of multilayer strand compacting thigh steel cable of the present utility model is made of annular wire rope, and steel wire rope uses compaction-strand steel wire rope.
Steel wire rope comprises central strand 2,6 internal layer thighs 3,12 outer layer strand and 16 outer layer strand.Wherein time outer layer strand comprises 6 thick strand 5 and 6 thin strand 4.Per sharely in the steel wire rope twist with the fingers a core wire by 6 cover wire bags and form, wherein cover wire approximate trapezoid, the approximate regular hexagon of core wire, and be face between the per share interior steel wire of steel wire rope and steel wire and contact shape.
Its preparation method is:
Arrange steel wire by noseplate twisting with the fingers on strand car, mouthful be compacted to steel wire rope with the wolfram steel mould and be deformed to desired structure through closing up, effectively eliminate again the stress of thigh through post-former, then be received on the I-beam wheel.With the mode of production of die drawing, when twisting with the fingers thigh, carry out (cold-)drawn (steel)wire rope rope strand with mould, a change strand interior wire shape makes it to be face contact shape, is prepared into central strand 2, internal layer thigh 3, inferior skin carefully thigh 4, the thick thigh 5 of inferior skin and outer layer strand 6.
Close when restricting, each personal share arranges by noseplate on finished car, through pre-former, by closing up a mouthful compression, effectively eliminates the stress of thigh through post-former more again, then is received on the I-beam wheel.
Thigh is carried out with strand hinged in the steel wire rope two ends, be prepared into the hinged rigging of multilayer strand compacting thigh steel cable.
The structure of rope strand is face contact shape through the mould extruding, improved steel wire rope metal effective area, therefore the rupture pull force coefficient of steel wire rope is high, simultaneously, because the steel wire rope of this kind structure is twisted with the fingers a central strand twisting by three layers of thigh bag and formed, rigging does not rotate under the state that does not carry, and its resistance rotation performance is good, have stronger crush resistance and resistance to shock loads performance, anti-wear performance is good, long service life.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
