Description

A kind of used for high-speed railway galvanized steel wire rope of high-strength corrosion-resisting

Technical field

The utility model relates to a kind of rope, refers in particular to metallic cable.

Background technology

Compensation arrangement is the critical facility of high-speed railway, compensation arrangement requires very high to employed steel wire rope, the intensity that not only needs superelevation, and have high anti-corrosion property, ABRASION RESISTANCE and resist to press property, using maximum at present is the steel wire rope of the good zinc-plated multiply structure of ABRASION RESISTANCE, as 35W * 7,17 * 7,18 * 7 etc., since strand with strand in contact condition be that dotted line contact or full point contacts, these contact conditions are instability extremely, the galvanized steel wire rope intensity good for ABRASION RESISTANCE does not reach 2160N/mm ², actual rupture pull force is little, is difficult to bear big load; As select bright wire rope for use, then corrosion resistant performance does not reach requirement.Because the present limitation of structure, steel wire rope are difficult to reach simultaneously intensity height, rotproofness, ABRASION RESISTANCE, requirement that flexibility is good.

The utility model content

The purpose of this utility model has corrosion resistance, ABRASION RESISTANCE, the used for high-speed railway galvanized steel wire rope that flexibility is good simultaneously again for a kind of intensity height is provided.

The technical scheme that realizes above-mentioned purpose is:

A kind of used for high-speed railway galvanized steel wire rope of high-strength corrosion-resisting, the multistrand rope of forming by central strand, internal layer thigh and outer layer strand, described central strand is 1 strand steel wire rope, the internal layer thigh is to be evenly distributed on central strand 10 strand steel wire ropes on every side, outer layer strand is 10 strand steel wire ropes that are evenly distributed on around the internal layer thigh, strand with thigh between contact for line.

Central strand adopts the structure of 19W, the center is 1 steel wire, its outer internal layer of forming by 6 equally distributed steel wires, the skin of being made up of 12 equally distributed steel wires in the internal layer outside is in 12 steel wires, there are 6 to be thick wire, other 6 is finer wire, and arrange thickness steel wire space, at the recess embedding thick wire of adjacent 2 steel wire of internal layer, twist with the fingers finer wire at the bossing of every steel wire of internal layer, be the line contact between the steel wire.

The center of internal layer thigh is 1 steel wire, is made up of 6 equally distributed steel wires on every side, is the line contact between the steel wire.

Outer layer strand adopts 25F filled type structure, and the center is 1 steel wire, the internal layer of being made up of 6 equally distributed steel wires in the outside, recess at adjacent 2 steel wire of internal layer embeds filler wires, totally 6, evenly distribute 12 steel wires as skin in the outside of internal layer, be the line contact between the steel wire.

Steel wire is the category-B zinc-coated wire

Central strand in the such scheme adopts W watt of woods to gulp down the formula structure, has soft, resistant to bending characteristics.The internal layer thigh plays a part to support and improve the steel wire rope effective area, and it has, and steel wire quantity is few, contact condition is relatively stable, comparatively Rou Ruan characteristics.The outer F filled type structure that adopts, this kind structure effective area is big, resists pressure property height.

The utility model closes the one-shot forming of when rope, produces having on the above rope-forming machine of 20 dishes, and the ectonexine thigh carries out spiral rotation round a central strand simultaneously, and the contact condition between every steel wire all is that line contacts.

The utlity model has following beneficial effect:

1, because steel wire rope adopts the brand new of 1 * 19W+10 * 7+10 * 25FI-2160-￠ 9～￠ 10mm, high strength, the high tenacity of steel wire rope have been guaranteed, cold drawn finished product steel wire adopt dried draw to combine with the water tank drawing carry out simultaneously, not only improved mechanical performance, also guaranteed production efficiency.

2, close when rope disposable twisting and form, guarantee in the steel wire rope every, be the line contact condition between per share, increase the effective area of steel wire rope, thereby improved the rupture pull force of steel wire rope; Do the time spent when steel wire rope is subjected to external force, the levels steel wire does not produce mutual extrusion and bending, and the compact stress that steel wire bears is less, and fatigue behaviour is good.

3, go up under the effect of stating frame mode zinc-coated wire and can fortunately bring into play antiseptic property, improved service life.

4, close rope and adopted the Xi Lushi structure, increased the flexibility of steel wire rope.
