Abstract
The utility model provides a 3*7 wire rope, which relates to a wire rope used as a highway guardrail, which comprises three jets of steel wires which are intertwisted, each jet of steel wire core is a steel wire, and the jet surface is six steel wires. The 3*7 wire rope is intertwisted by three jets of steel wires, each jet of the steel wire core is a steel wire, the jet surface is six steel wires, a steel wire core 2 which is enclosed by the six steel wires 1 is intertwisted to form a steel wire jet, and then three steel wire jets are intertwisted to form the wire rope with a 3*7 structure. The 3*7 wire rope has light weight, large breaking load, excellent elasticity, excellent shock absorption effect and excellent anti-impact performance. The 3*7 wire rope is used as the highway guardrail, can effectively intercept accident vehicles which rush to the guardrail, has excellent inclusiveness for the vehicles, solves the safety problem of the vehicles which drive on a highway, and has long service life and low cost.
Description
Technical field
The utility model relates to a kind of steel wire rope as freeway guardrail.
Background technology
Steel wire rope is because of thick than other all kinds of steel wire diameter, overlay coating is thick, have good springiness, shock-absorbing effect is good, crashworthiness is good, to good, the corrosion resistance of pardon of vehicle, be to be used for the national highway job facilities, play a kind of product of security protection effect for running car.Though domestic have all kinds of structure steel wire ropes, as 6 * 37,6 * 36,6 * 7,18 * 7 etc., the strand wire of these structures is many, weight greatly, not shock-resistant and corrosion, they are mainly used in during building elevator and goods and mining industry promote.Have 1 * 37, its breaking load is little, crashworthiness is poor, can only be used for small-sized device for use in fishing trawl.
Traffic accident takes place in automobile sometimes in running at high speed, have smash guardrail after, rout up, smooth highway get on the bus rout up after, problem is also a little bit smaller, as on the hill path, car is translated into bottom of trench, will cause the major casualties of car crash.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide that a kind of in light weight, breaking load is big, good springiness, shock-absorbing effect is good, crashworthiness is good 3 * 7 steel wire ropes.
The implementation of the utility model purpose is, 3 * 7 steel wire ropes constitute by 3 strands of steel wires are stranded, and per share wire-core is 1 steel wire, and a strand face is 6 steel wires.
The utility model constitutes by 3 strands of steel wires are stranded, and per share wire-core is 1 steel wire, and a strand face is 6 steel wires.The utility model is in light weight, breaking load is big, good springiness, shock-absorbing effect is good, crashworthiness is good.The utility model can effectively be tackled the vehicle that meets accident that is flushed to guardrail as freeway guardrail, and is good to the pardon of vehicle, solved the safety problem of automobile at running on expressway, and long service life, cost are low.
Description of drawings
Accompanying drawing is the utility model structure cutaway view
The specific embodiment
With reference to accompanying drawing, the utility model constitutes by 3 strands of steel wires are stranded, and per share wire-core 2 is 1 steel wire, and a strand face is 6 steel wires 1.6 steel wires of the present utility model 1 are around wire-core 2 stranded formation steel strands, again with the steel wire rope of 3 stranded formation 3 * 7 structures of steel strand.
The utility model constitutes by 3 strands of steel wires are stranded, and per share wire-core is 1 steel wire, and a strand face is 6 steel wires.The utility model is in light weight, breaking load is big, good springiness, shock-absorbing effect is good, crashworthiness is good.The utility model can effectively be tackled the vehicle that meets accident that is flushed to guardrail as freeway guardrail, and is good to the pardon of vehicle, solved the safety problem of automobile at running on expressway, and long service life, cost are low.
