Abstract
The invention relates to a non-rotating wire rope which comprises an inner-layer rope body and an outer-layer rope body, wherein the inner-layer rope body comprises center strands, inner-layer strands and filling strands, the outer-layer rope body comprises a plurality of independently compressed outer-layer strands, the twisting direction of the outer-layer rope body is opposite to the twisting direction of the inner-layer rope body, and the center strands are made of an oily high polymer material.
Description
Technical field
The present invention relates to steel wire rope technical field, be specifically related to a kind of non-rotating cable.
Background technology
Steel wire rope is widely used in being related to a plurality of industries of national economy, as industries such as mining, metallurgy, tourism, fishery, building, machineries.In use, the fracture of wire causing because operation and maintenance is improper and to scrap phenomenon of common occurrence.Have data to show, in the steel wire rope of scrapping, fatigue damage only accounts for 10～15%, and 70～80%, because of corrosion, cause.
Non-rotating cable refers to that steel wire rope is when vertically depending weight duty, can not produce a kind of performance around self axis rotation.The not verticity of steel wire rope, concerning using, has very important meaning.Under the use occasions such as sinking shaft when New Built Mine, various crane lifting weights, all require steel wire rope not rotate, could normally work.If wire rope rotating, can affect operating efficiency and property life security, concerning steel wire rope itself, due to rotation, can constantly reduce fatigue behaviour in addition, thereby affect the service life of steel wire rope.For single-strand wire rope, should dwindle the lay pitch of thigh, and the lay pitch of increase rope, and reduce number of share of stock as far as possible, and thigh is made to abnormity strand, so that the moment sum of increase thigh is offset the moment of rope, thereby meet non-rotary requirement.
The main boom hoist cable of crawler type lifting in the market mainly adopts 35 (W) * 7 steel wire ropes, in use, exist steel wire rope directly through bigger than normal, while rising and falling up and down main hook, be prone to grab, fall not smooth, easily recurring structure destroys, the quality problems such as service life is short, simultaneously because 35 (W) * 7 group number of share of stock amount is more, tissue is produced and brought certain difficulty, easy existence group rope strand tension force non-uniform phenomenon, the quality problems that exist with 35 (W) * 7 steel wire ropes for the main lifting of crawler crane, for this reason, user is badly in need of wanting to buy than the more excellent steel wire rope of 35 (W) * 7 performance, be badly in need of developing a kind of identical anti-verticity that has, and the more excellent main lifting Special high-strength of the crawler crane compaction-strand steel wire rope of other performance, meet the safe of 15 * K7:IWRC (K) high-strength compacted anti-rotation wire rope, softness is good, the main hook specification requirement smoothly of rising and falling up and down.
Summary of the invention
The object of the present invention is to provide a kind of damage steel wire rope that do not rotate.
For reaching this object, the present invention by the following technical solutions:
A non-rotating cable, described steel wire rope comprises internal layer rope and outer rope, described internal layer rope comprises central strand, internal layer thigh and fills thigh; Described outer rope comprises the outer layer strand of many independent compactings; Described outer rope is twisted with the fingers to twisting with the fingers to contrary with internal layer rope; Described central strand adopts containing oil polymer macromolecular material.
Central strand of the present invention adopts the internal lubrication that can guarantee steel wire rope containing oil polymer macromolecular material.
The lay pitch of described every outer layer strand is 5～8 times of strand diameter, for example, can select 5.01～7.96 times, 5.6～7.68 times, 5.89～7.24 times, 6～7.04 times, 6.34～6.8 times, 6.5 times etc., all can be used for implementing the present invention.
The lay pitch of described every outer layer strand is 6.4～7 times of strand diameter.The lay pitch is the extremely important twisting process parameter of of steel wire rope.There is to significant impact the aspects such as construction of wire rope performance and output, are also important technological parameters of twisting device.The lay pitch is defined as follows: when twisting with the fingers strand or closing rope, and the air line distance between the terminal that steel wire rotates a circle around wire rope core around thigh core or rope strand.
The compression ratio of described every outer layer strand when independent compacting is 5～14%, for example, can select 5.01～13.9%, 5.46～12.3%, 7～11.5%, 7.34～10.6%, 8～9.7%, 9.3% etc., all can be used for implementing the present invention.
The compression ratio of described every outer layer strand when independent compacting is 7～12%.
Described polymer macromolecular material is the combination of a kind of in nylon-66, nylon-6 or polypropylene or at least two kinds.Typical but non-limiting example comprises, nylon-66, nylon-6, polypropylene, the combination of nylon-66 and nylon-6, nylon-66 and polyacrylic combination, nylon-6 and polyacrylic combination, nylon-66, nylon-6 and polyacrylic combination, all can be used for implementing the present invention.
The steel wire rope that the present invention is finally twisted into is again through forging secondary compaction, and the compression ratio while forging is 15～25%, makes it to have good ABRASION RESISTANCE and increases the contact area that contacts with it parts.Utilize the intrinsic anti-revolving property of outer rope simultaneously, reduce the lay pitch of thigh, strengthen the lay pitch of rope, make it to reach anti-rotational object.
Compare with prior art scheme, the present invention has following beneficial effect:
Steel cord structure intensity of the present invention is high, rupture pull force is high, anti-verticity is good, also has good pliability simultaneously, meets the instructions for use of lifting owner boom hoist cable completely, and cost of manufacture is low.
Below the present invention is described in more detail.But following example is only simple and easy example of the present invention, does not represent or limit the scope of the present invention, and protection scope of the present invention is as the criterion with claims.
