Abstract

The utility model relates to a steel cable of an anchor of a contact net, which comprises a central strand, an inner layer and an outer layer, wherein the periphery of the central strand is the inner layer, the periphery of the inner layer is the outer layer, nineteen Warrington type steel cables are twisted to form the central strand, the inner layer comprises twelve strands of inner layer steel cable strands, seven steel cables are twisted to form each strand of the inner layer steel cable strands, the outer layer comprises 12 strands of outer layer steel cable strands, twenty-five filling type steel cables are twisted to form each strand of the outer layer steel cable strands, the wire pitch of the twelve inner layer steel cable strands inside the inner layer is as same as the wire pitch of the twelve outer layer steel cable strands inside the outer layer, and each strand of the inner layer steel cable strands are in line contact with each strand of the outer layer steel cable strands. The steel cable of the anchor of the contact net has the advantages of being simple in structure, high in breaking force, long in fatigue service life, good in abrasion resistance and corrosion resistance and the like.

Description

The contact net steel wire rope that casts anchor

Technical field

The utility model relates to a kind of steel wire rope, particularly a kind of contact net steel wire rope that casts anchor.

Background technology

At present, electrification railway contact net weighs down takes turns the steel wire rope that uses on the tensioner that casts anchor, comprising 156 steel wires; Because the steel wire negligible amounts, bulkfactor is low, and the sth. made by twisting system stress between thigh and the thigh is bigger; In use, steel wire rope rotates easily, and thigh is little with the contact area of thigh simultaneously; Surface irregularity, fatigue life is little.

Summary of the invention

The purpose of the utility model is in order to overcome above deficiency, provide a kind of simple in structure, rupture pull force is high, tired long service life, contact net that wear-resisting corrosivity is good are casted anchor steel wire rope.

The purpose of the utility model realizes through following technical scheme: a kind of contact net steel wire rope that casts anchor, comprise central strand, and the periphery of central strand is an internal layer; The periphery of internal layer is outer; Central strand gulps down the formula steel wire by 19 Gen Walin and twists with the fingers, and internal layer is made up of 12 strands of steel wire of internal layer thighs, and per share steel wire of internal layer thigh is twisted with the fingers by 7 steel wires; Skin is made up of 12 strands of cover wire thighs; Per share cover wire thigh is twisted with the fingers by 25 filled type steel wires, and the lay pitch of 12 strands of cover wire thighs in the lay pitch of 12 strands of steel wire of internal layer thighs in the internal layer and the skin is consistent, and is line between per share steel wire of internal layer thigh and the per share cover wire thigh and contacts.

The utility model compared with prior art has the following advantages:

1, adopt high-strength galvanized steel wire production, adopt parallel closely knit sth. made by twisting on the structure, steel wire always reaches 403 with number, steel wire rope from the coarse to fine, bulkfactor reaches 0.7-0.76mm, the rupture pull force when keeping former thick specification state improves whole rope rupture pull force greatly;

Adopt after-processing technology when 2, producing, the sth. made by twisting system stress that produces when twisting with the fingers thigh and closing rope is by fully elimination, and fatigue performance is good, and steel wire rope has good not rotatory, has improved tired service life;

3, the slit diminishes between thigh and the thigh, and the slit is closure state, and smooth surface is smooth, has strengthened when steel wire rope uses and the contact area of coupling race, makes the anti-extruding wear resistance raising of steel wire rope;

4, after forging, owing to the mutual extrusion effect between thigh and the thigh, make the sectional area of thigh no longer keep original circular state, contact area increase between thigh and the thigh, steel cord structure is more stable, the structural stretch minimizing in the use;

5, select high-quality high-low temperature resistant grease for use; The steel wire of internal layer thigh adopts twists with the fingers burst oily technology of pouring, and the cover wire thigh adopts and closes rope immersion oil technology, has grease-filled fully between the rope strand; Friction when reducing the steel wire rope use between thigh and the thigh; The environmental requirement of harsh weather when satisfying the steel wire rope use, the wear-resisting corrosive nature of raising steel wire rope, thereby the service life of improving steel wire rope.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Label among the figure: 1-central strand, 2-steel wire of internal layer thigh, 3-cover wire thigh, a 4-watt woods gulp down formula steel wire, 5-steel wire, 6-filled type steel wire.

The specific embodiment:

In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.

Show cast anchor a kind of embodiment of steel wire rope of a kind of contact net of the utility model like Fig. 1, comprise central strand 1, the periphery of central strand 1 is an internal layer; The periphery of internal layer is outer; Central strand 1 gulps down formula steel wire 4 by 19 Gen Walin and twists with the fingers, and internal layer is made up of 12 strands of steel wire of internal layer thighs 2, and per share steel wire of internal layer thigh 2 is twisted with the fingers by 7 steel wires 5; Skin is made up of 12 strands of cover wire thighs 3; Per share cover wire thigh 3 is twisted with the fingers by 25 filled type steel wires 6, and the lay pitch of 12 strands of cover wire thighs 3 in the lay pitch of 12 strands of steel wire of internal layer thighs 2 in the internal layer and the skin is consistent, and is line between per share steel wire of internal layer thigh 2 and the per share cover wire thigh 3 and contacts.

The employing high-strength galvanized steel wire is produced, and adopts parallel closely knit sth. made by twisting on the structure, and steel wire always reaches 403 with number, steel wire rope from the coarse to fine, bulkfactor reaches 0.7-0.76mm, the rupture pull force when keeping former thick specification state improves whole rope rupture pull force greatly; Adopt after-processing technology during production, the sth. made by twisting system stress that produces when twisting with the fingers thigh and closing rope is by fully elimination, and fatigue performance is good, and steel wire rope has good not rotatory, has improved tired service life; The slit diminishes between thigh and the thigh, and the slit is closure state, and smooth surface is smooth, has strengthened when steel wire rope uses and the contact area of coupling race, makes the anti-extruding wear resistance raising of steel wire rope; After forging, owing to the mutual extrusion effect between thigh and the thigh, make the sectional area of thigh no longer keep original circular state, contact area increase between thigh and the thigh, steel cord structure is more stable, the structural stretch minimizing in the use; Select high-quality high-low temperature resistant grease for use; The steel wire of internal layer thigh adopts twists with the fingers burst oily technology of pouring, and the cover wire thigh adopts and closes rope immersion oil technology, has grease-filled fully between the rope strand; Friction when reducing the steel wire rope use between thigh and the thigh; The environmental requirement of harsh weather when satisfying the steel wire rope use, the wear-resisting corrosive nature of raising steel wire rope, thereby the service life of improving steel wire rope.
