Description

The other hot-dip galvanizing steel wire rope of a kind of twin-stage

Technical field

The utility model relates to a kind of steel wire rope, and more particularly, it relates to the other hot-dip galvanizing steel wire rope of a kind of twin-stage.

Background technology

Under marine environment, engineer operation and the steel wire rope used by fishery fishing operation need through special process to improve the corrosion resistance of steel wire rope, the intensity of steel wire rope and anti-wear performance etc., at present conventional zinc-plated steel wire rope be exactly on steel wire rope plated surface zinc layers improve corrosion resistance.

The Chinese patent that the applicant is 96245662.4 at application number discloses a kind of external-rough type fishing wirerope, comprise wire rope core, be screwed in six rope strands around wire rope core, the structure of rope strand is stock core, outer steel wire floor in around stock core outside steel wire floor and inner steel wire floor, inside and outside steel wire floor is point cantact state, and every root steel wire diameter of outer steel wire floor is greater than the every root steel wire diameter of inner steel wire floor, outer steel wire floor is identical with the steel wire quantity of inner steel wire floor, the application passes through the diameter of outer steel wire floor to arrange larger at first, thicker than the zinc layers of inner steel wire floor in the zinc layers of the process China and foreign countries steel wire floor of zinc coat, improve corrosion resistance and ABRASION RESISTANCE, but meanwhile decline to some extent in flexibility because the excessive existence of adding zinc layers of diameter of outer steel wire floor result in whole steel wire rope, even if adopt the bag of point cantact mode of twisting with the fingers to improve the pliability of steel wire rope but not obvious in effect.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide the other hot-dip galvanizing steel wire rope of a kind of twin-stage while having original corrosion resistance, ABRASION RESISTANCE, also improve the flexibility of steel wire rope, avoid steel wire rope to beat tussling around phenomenon, improve service life.

For achieving the above object, the utility model provides following technical scheme: the other hot-dip galvanizing steel wire rope of a kind of twin-stage, comprise the first central strand and the 6 strand stocks of twisting around the first central strand, described rope strand comprises the second central strand, internal layer stock and outer layer strand from the inside to the outside successively, the material of described first central strand and the second central strand is fiber, internal layer stock is formed by 9 first steel wire twistings, and outer layer strand is formed by 9 second steel wire twistings.

As preferably, the zinc-plated grade of described first Steel Wire Surface is A level, and the zinc-plated grade of described second Steel Wire Surface is B level.

As preferably, the sth. made by twisting of described first steel wire and the second steel wire is to being left-hand lay, and described direction of rope lay is right-laid.

As preferably, in point cantact state between described first steel wire and the second steel wire.

Compared with prior art, the utility model has the advantage of: the second central strand of per share rope strand replaces original core wire, and the material of the first central strand and the second central strand is the pliability that fiber improves steel wire rope greatly, and the zinc-plated grade of the first Steel Wire Surface of rope strand is A level improves ABRASION RESISTANCE, the zinc-plated grade of the second Steel Wire Surface is B level, further raising ABRASION RESISTANCE, and the corrosion resistance of the zinc-plated pattern globality steel wire rope of bilayer, increase service life.

Accompanying drawing explanation

Fig. 1 is the sectional view of a kind of twin-stage of the utility model other hot-dip galvanizing steel wire rope embodiment.

Accompanying drawing illustrates: 10, steel wire rope; 20, the first central strand; 30, rope strand; 31, the second central strand; 32, internal layer stock; 321, the second steel wire; 33, outer layer strand; 331, the first steel wire.

Detailed description of the invention

With reference to accompanying drawing, a kind of twin-stage of the utility model other hot-dip galvanizing steel wire rope embodiment is described further.

Fig. 1 illustrates the sectional view of the other hot-dip galvanizing steel wire rope 10 of a kind of twin-stage, whole steel wire rope 10 comprises the first central strand 20 and the 6 strand stocks 30 of twisting in the first central strand 20 periphery, per share rope strand 30 comprises the second central strand 31 from the inside to the outside successively, internal layer stock 32 and outer layer strand 33, internal layer stock 32 is made up of 9 second steel wires 321, outer layer strand 33 is made up of 9 first steel wires 331 equally, the diameter of the first steel wire 331 is greater than the diameter of the second steel wire 321, the diameter of the first steel wire 331 is 1.26mm, the diameter of the second steel wire 321 is 0.63mm, the diameter of the first steel wire 331 is 2 times of the second steel wire 321 diameter, first steel wire 331 and the second steel wire 321 are all through hot dip galvanizing process, the zinc-plated grade on the first steel wire 331 surface is A level, the zinc-plated grade on the second steel wire 321 surface is B level, the surperficial minimum zinc layer weight of first steel wire 331 is 157g/m ², the surperficial minimum zinc layer weight of the second steel wire 321 is 48 g/m ², internal layer stock 32 and outer layer strand 33 all with the sth. made by twisting of left-hand lay to twisting, and the sth. made by twisting of whole steel wire rope 10 is to being right-laid, namely the sth. made by twisting method of steel wire rope 10 is right ordinary lay, avoid steel wire rope 10 to occur loose, and internal layer stock 32 is point cantact with the contact condition of outer layer strand 33, improves the flexibility of steel wire rope 10.The material of the first central strand 20 and the second central strand 31 is fiber, improves the flexibility of steel wire rope 10.

The steel wire rope 10 adopting the not zinc-plated mode of twin-stage to make greatly improves in corrosion resistance and ABRASION RESISTANCE, and the central strand material of the central strand of steel wire rope 10 and per share rope strand 30 is fiber, compare the flexibility that core wire improves steel wire rope 10, the two zinc-plated mode of perfect adaptation, namely be guaranteed in corrosion resistance and ABRASION RESISTANCE, in turn ensure that steel wire rope 10 has good flexibility.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
