Abstract

The utility model provides a wire rope is moulded to three -strand clamp, includes the rope strand that the three -strand alternately each other was twisted with the fingers, the rope strand includes the thigh core of being made by the flaxen fiber, strand core is steel wire layer and outer steel wire layer in outwards the winding has in proper order, and outer steel wire layer surface scribbles anti -corrosion grease and cladding and plastic film, the outer winding of plastic film has the plastics silk. By adopting the above technical scheme, can reduce plastic film on the one hand under the protection of plastics silk, on the other hand has completely cut off rope strand and external contact under plastic film's cladding, and the main sea water that can prevent gets into protective layer and steel wire direct contact, also can prevent that the grease on rope strand surface from oozing simultaneously, and then improve the anticorrosive ability of rope strand.

Description

A kind of three strands of folder plastic steel wire ropes

Technical field

The utility model relates to a kind of three strands of folder plastic steel wire ropes.

Background technology

In fishery is fished for, due to the frequent traction of steel wire rope, steel wire rope directly with net hauler reel, ship side friction, cause that hauling is mechanical, ship side heavy wear; Meanwhile, also destroy the zinc coat of Steel Wire Surface, thus significantly accelerate the corrosion rate of steel wire.When manual auxiliary hauling, because burn into weares and teares the disrumpent feelings steel wire caused, often puncture the hand of fisherman; In addition, the grease on steel wire rope not only stains both hands, also owing to decreasing frictional force, makes gripping steel wire rope feel difficulty.Thus normal operation has been had a strong impact on.

For this reason, part Production for Steel Wire enterprise can arrange protective layer to steel wire rope surface, the Chinese patent " plastic coated galvanized steel wire for fishing " being 91208274.7 as application number discloses a kind of plastic coated galvanized steel wire for fishing, its core is the protective layer that the outer circumference surface of steel wire rope is coated with fiber or plastics and makes, or twist together again after the protective layer that in steel wire rope, the outer circumference surface of per share steel wire is made with fiber or plastics is respectively coated, although this steel wire rope can overcome the defect of the corrosion and damage by heavy wear in operation engineering, but the protective layer made due to fiber or plastics also has certain space, so seawater still may enter protective layer inside and directly contact in steel wire, the seawater simultaneously entered is not easy again to discharge, in the course of time will accelerate zinc layers to be corroded, finally steel wire rope also can be caused to be corroded.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of anti-sealing directly to contact with steel wire, wear-resistant, corrosion resistant three strands of folder plastic steel wire ropes.

For achieving the above object, the utility model provides following technical scheme: a kind of three strands of folder plastic steel wire ropes, comprise the rope strand that three bursts of intersections are twisted with the fingers mutually, described rope strand comprises the stock core be made up of flax fibre, described stock core is outwards wound with inner steel wire floor and outer steel wire floor successively, outer steel wire floor surface scribbles etch-proof grease and is coated with plastic sheeting, is wound with plastic wire outside described plastic sheeting.

By adopting technique scheme; plastic sheeting can be reduced on the one hand under the protection of plastic wire; rope strand and extraneous contact has been completely cut off on the other hand at the coated lower of plastic sheeting; mainly can prevent from seawater from entering protective layer directly contacting with steel wire; also can prevent the grease on rope strand surface from oozing out simultaneously, and then improve the antiseptic power of rope strand.

Of the present utility modelly to be set to further: the sth. made by twisting of the rope strand of described steel wire rope is to being right-laid, and the sth. made by twisting of steel wire is to being right-laid., can strengthen the centripetal force of steel wire rope so further, the very high sth. made by twisting power effect of steel wire rope entirety, reduces the possibility that steel wire rope falls apart.

Further be set to: described plastic wire is mixed by polypropylene and polyethylene; such plastic wire to possess again the character of certain cold-resistant, acidproof, high strength under the prerequisite having good stretch capability, heat resistance and smoothness; make protective layer more difficult damaged, thus be conducive to playing better protection to rope strand.

Accompanying drawing explanation

Fig. 1 is the strand structure schematic diagram of a kind of three strands of folder plastic steel wire ropes of the present utility model;

Fig. 2 is the structural representation of a kind of three strands of folder plastic steel wire ropes of the present utility model.

In figure: 1, rope strand; 2, PP plastic sheeting; 3, protective layer; 4, stock core; 5, inner steel wire floor; 6, outer steel wire floor.

Detailed description of the invention

Referring to figs. 1 through Fig. 2, the utility model embodiment is described further.

A kind of three strands of folder plastic steel wire ropes of the utility model, comprise the rope strand 1 that three intersections twist with the fingers plating zinc on surface mutually, the structure of every bar rope strand 1 comprises the stock core 4 that flax fibre is made, outside around inner steel wire floor 5 and outer steel wire floor 6 successively around stock core 4, in steel wire floor 5 are point-like contacts states with outer steel wire floor 6, the outer peripheral face of outer steel wire floor 6 is coated with PP plastic sheeting 2, rope strand 1 and extraneous contact can be completely cut off like this, what most importantly prevent seawater and rope strand 1 directly contacts and the exosmosing of rope strand 1 surface oil, thus reduces the degree that rope strand 1 is corroded.In addition; the tight twisting of PP plastic sheeting 2 outer peripheral face plastic wire and is made protective layer 3; the zinc layers on plastic sheeting 2 and steel wire can be prevented like this to be worn, thus to improve the anti-wear performance of steel wire rope further, finally again three rope strands 1 be twisted together under the work of rope-forming machine.

Further scheme is: the rope strand 1 of steel wire rope and the sth. made by twisting of steel wire, to being all right-laid, can strengthen the sth. made by twisting power effect of steel wire rope entirety like this, thus reduces the possibility that steel wire rope in use falls apart, and then is conducive to the efficiency improving fishery operation.

Further scheme is: protective layer 3 material of steel wire rope is synthesized by the ratio of polypropylene and polyethylene 7:3 in mass ratio; it had not only possessed good stretch capability, heat resistance and smoothness but also had had the performance of certain cold resistance, acid resistance and high strength; thus enhance the anti abrasive ability of protective layer 3; improve the wear-resistant and corrosion resistant ability of the entirety of steel wire rope; reduce the cost of fishery work, provide operating efficiency.

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.
