Description

Composite construction strand compaction wire rope

Technical Field

The utility model relates to a composite construction strand compaction wire rope and manufacturing method thereof belongs to metal product processing technology field.

Background

The steel wire ropes in the application fields of large equipment lifting, highway bridge sling and the like are generally point-line contact type steel wire ropes, and not only are primary bending stress caused by external round objects such as pulleys or drums received in the using process of the steel wire ropes, but also secondary bending stress is generated due to severe mutual extrusion caused by excessive slippage of steel wires between rope layers, and meanwhile, the steel wire ropes are small in filling coefficient, low in breaking tension and large in use limitation, and cannot meet the actual requirements of continuously-increased fatigue resistance and breaking tension, so that the structural requirements, twisting methods and performance characteristics of the steel wire ropes need to be researched and improved.

SUMMERY OF THE UTILITY MODEL

The utility model relates to a solve present main equipment and promote, point line contact type wire rope of application fields such as highway bridge hoist cable usefulness, except receiving the primary bending stress that outside circular articles such as pulley or reel caused in its use, still exist the serious mutual extrusion that the excessive steel wire slided between the rope layer and caused and produce the secondary bending stress, its fill factor is little simultaneously, breaking force is low and use the limitation big, and be difficult to satisfy constantly increasing fatigue resistance, breaking force's actual demand's technical problem.

In order to solve the technical problem, the utility model discloses a following technical scheme:

a composite structure strand compacted steel wire rope is 8 xK 80WSNS + IWRC and sequentially comprises a central strand 1, an inner layer strand 2 and an outer layer strand 3 from inside to outside, and the total number of steel wires is not less than 941;

the central strand 1 is 55SWS in structure, is one in number and is formed by twisting 55 steel wires at one time;

the inner layer strand 2 has a structure of 41WS or 55SWS, the number of the inner layer strand is six or eight, and each inner layer strand is formed by twisting at least 41 steel wires at one time;

the outer layer strand 3 structure be 80WSNS, the quantity is eight, every includes strand inner 31 and strand inner and outer 32 from inside to outside in proper order, every comprises 80 steel wires, divides twice system of twisting.

The structure of the inner layer 31 of the strand is 1+7+7/7+14, and the number of the steel wires of the inner layer of the strand is 36.

The structure of the inner layer 32 and the outer layer 32 of the strand is 22+22, and the number of steel wires of the inner layer and the outer layer of the strand is 44.

Adopt above-mentioned technical scheme's beneficial effect:

1. the utility model discloses because wire rope center thigh, inlayer thigh and outer thigh are all through the roller compaction, be the face contact structural state between steel wire and the steel wire in the wire rope, the wire rope structure is inseparable, each thigh adopts the mode of once twisting with the fingers, make to be line contact structural state between steel wire rope strand and the thigh, have the required general soft characteristic ability of assurance wire rope, wire rope each thigh has all carried out the plastic-coated processing simultaneously for wire rope wear resistance, fatigue resistance and bearing capacity are showing and are increasing, and the life-span increases.

2. The utility model has the structure of 8 xK 80WSNS + IWRC, and is formed by twisting a central strand, six or eight inner layer strands and eight outer layer strands; compacting and coating plastics on the central strand and the inner and outer layer strands; twisting the outer layer strand twice, compacting after the first twisting, and then compacting by twisting for the second time; the steel wires formed in the steel wire rope strand are in a surface contact state and are tightly combined, and secondary bending caused by excessive slippage among the steel wires does not exist.

3. The utility model discloses wire rope metal filling coefficient is high, and effective metal section area increases, the dispersed stress that receives during the use, so wearability, fatigue resistance and breaking force are showing and are improving.

Detailed Description

Example one

A composite structure strand compacted steel wire rope is 8 xK 80WSNS + IWRC and sequentially comprises a central strand 1, an inner layer strand 2 and an outer layer strand 3 from inside to outside, and the total number of steel wires is 941;

the inner layer strand 2 is 41WS in structure, six in number and formed by twisting 41 steel wires once each;

Example two

A composite structure strand compacted steel wire rope is 8 xK 80WSNS + IWRC and sequentially comprises a central strand 1, an inner layer strand 2 and an outer layer strand 3 from inside to outside, and the total number of steel wires is 1135;

the inner layer strand 2 is 55SWS in structure, the number of the inner layer strand is eight, and each inner layer strand is formed by twisting 55 steel wires at one time;

The utility model discloses because wire rope center thigh, inlayer thigh and outer thigh are all through the roller compaction, be the face contact structural state between steel wire and the steel wire in the wire rope, the wire rope structure is inseparable, each thigh adopts the mode of once twisting with the fingers, make to be line contact structural state between steel wire rope strand and the thigh, have the required general soft characteristic ability of assurance wire rope, wire rope each thigh has all carried out the plastic-coated processing simultaneously for wire rope wear resistance, fatigue resistance and bearing capacity are showing and are increasing, and the life-span increases.
