Description

A kind of anti-extrusion, endurance Spiral digging machine steel wire rope

Technical field

The utility model relates to a kind of steel wire rope, relates in particular to a kind of crush resistance, endurance Spiral digging machine steel wire rope.

Background technology

At present on important machinery such as Spiral digging machine and piling machine, use 6 * 19S, 6 * 29FI, the isostructural steel wire rope of 6 * 31WS, 6 * 36WS, because the environment of this equipment availability is more abominable, bear the big and difficulty or ease control of load-carrying, problems such as meeting is poor, not withstand voltage because of the steel wire rope flexibility, fatigability difference, and it is short service life to be directed at steel wire rope.

The utility model content

The utility model is intended to overcome above the deficiencies in the prior art, provides that a kind of new structure is anti-extrusion, the endurance Spiral digging machine

Use steel wire rope.

The utility model technical solution problem adopts following technical scheme:

Anti-extrusion, endurance Spiral digging machine steel wire rope are characterized in, comprise central strand, outer layer strand and main thigh; The number of share of stock of described outer layer strand is that 6 also even bags are twisted with the fingers in the outside of central strand, and the number of share of stock of described main thigh is that 6 also even bags are twisted with the fingers the outsides in outer layer strand; Described central strand and outer layer strand all adopt a watt woods to gulp down the formula structure, and the center is a core wire, are evenly to wrap 6 steel wires twisting with the fingers core wire in the core wire outside; Described main strand is adopted watt woods to gulp down-fabricated structure of Xi Lushi, the center is 1 core wire, ground floor is that evenly the bag sth. made by twisting is at 6 steel wires in the core wire outside, and the second layer is that even bag is twisted with the fingers 12 steel wires outside ground floor, and the 3rd layer is evenly to wrap 14 steel wires twisting with the fingers in the second layer outside; Each strand with strand between contact for line.

Further, 12 steel wires of the described main strand second layer, 6 is finer wire, 6 is thick wire; 6 finer wires embed the outer projection position of ground floor steel wire, embed thick wire respectively in 6 outer side clearances that form between 6 steel wires of ground floor; The ground floor steel wire is line with core wire and contacts, and for line contacts, the compound steel silk is the fan-shaped annular that goes up between second layer steel wire and the ground floor steel wire, is between compound steel silk and the second layer steel wire to contact, and is face between the compound steel silk and contacts.Described finer wire is a relative notion with thick wire, as long as the diameter of thick wire is greater than the diameter of finer wire.

Anti-extrusion, the fatigue proof Spiral digging machine of the present utility model preparation method of steel wire rope may further comprise the steps:

A, twist with the fingers strand: adopt preforming process, make the steel strand distortion, eliminate the residual stress of steel strand then with post-former, make steel strand straight, will closing up mouth and carry out oil spout during the thigh of the production center at strander;

B, close rope: 6 bursts of outer layer strand of steel wire rope are carried out the helicity rotation round central strand, 6 main strand is separated every thigh by noseplate on the crank closer car, through behind the pre-former, use the line ball mold pressing tight again, compression ratio is 8%, and the process post-former is eliminated the residual stress in the rope again, and outer layer strand is carried out helicity rotation bag sth. made by twisting then, steel wire rope closes the rope back and adopts 5～8% rates of forging to forge, and evenly coats surface lubrication fat then and promptly gets described steel wire rope.

The utlity model has following beneficial effect:

1, per share steel wire master thigh is designed to 33, and steel wire rope by such design, can strengthen the flexibility and the ABRASION RESISTANCE of steel wire rope through twisting with the fingers thigh and closing rope and divide the secondary twisting to form.

2, steel wire rope master thigh is the fabricated structure that " WS " Wa Lin gulps down formula-Xi Lushi, and the contact condition of each steel wire is a dotted line contact shape in strand, makes the more soft steel wire rope prehensile of having restricted that increases of steel wire rope.

3, steel wire rope is by a burst compaction process technology, make steel wire rope tightr, the effective area and the compactedness of steel wire rope have been increased greatly, reduced the construction of wire rope elongation, stablize the contact condition between each strand, improved the crush resistance and the impact resistance of steel wire rope, the load of being born simultaneously can be far above the value of prescribed by standard more than 15%.
