Abstract

The utility model discloses a compaction steel wire rope for a load elevator, which comprises a center strand, inner layer strands and outer layer strands. Each outer layer strand consists of outer layer steel wires, inner layer steel wires and a center steel wire and is of a seal type structure and the steel wires are in surface contact; each inner layer strand is formed by uniformly coating and twisting 6 steel wires outside a center steel wire; and the center strand is of a Warrington-type structure, is formed by uniformly coating and twisting 6 inner layer steel wires outside a center steel wire and consists of 6 thin steel wires and 12 thick steel wires serving as the inner layer steel wires. After the steel wire rope disclosed by the utility model is adopted, the contact area of the steel wire rope and a traction sheave is large and the compaction steel wire rope has good wear resistance and has good bearing capacity and rotation prevention performance.

Description

A kind of load-carrying compacted steel wire rope for elevator

Technical field

The utility model relates to a kind of metallic cable, relates in particular to a kind of load-carrying compacted steel wire rope for elevator.

Background technology

Steel wire rope is load-carrying original paper in the elevator, is almost bearing the total weight of elevator, and the safety that the quality of steel wire rope quality can directly have influence on elevator whether.In running process of elevator, steel wire rope is around traction sheave, and the unidirectional or alternating bending of diversion sheave.Steel wire rope is also bearing than higher specific pressure in grooving.So require steel wire rope to have than higher intensity, ABRASION RESISTANCE.And in running process of elevator, the rupture pull force of steel wire rope and bearing capacity also directly affect the security performance of elevator.Steel wire rope in the prior art in the load-carrying elevator is used common round-strand rope more; The steel wire rope of structure 8*19S+IWRC, it contacts with traction sheave and is circle burst contact, and contact area is little; ABRASION RESISTANCE is bad; And the bearing capacity of this type steel wire rope is relatively poor, and it is good inadequately that performance is revolved in resistance, and the uniformity of diameter poker is also not enough.

Summary of the invention

The utility model technical problem to be solved is that the load-carrying elevator is low with breaking force of rope in the prior art, and bearing capacity is not enough, and it contacts steel wire and is circle burst contact with traction sheave, and contact-making surface is little, and ABRASION RESISTANCE is bad, and resistance rotation performance is undesirable.

For addressing the above problem, the utility model provides a kind of load-carrying compacted steel wire rope for elevator, and it comprises central strand; Internal layer thigh and outer layer strand, said outer layer strand per sharely is made up of cover wire, steel wire of internal layer and core wire; Be the Xi Lushi structure, after compacting, be the face contact between the steel wire; Said internal layer thigh, it evenly wraps the sth. made by twisting core wire by 6 steel wires and forms; Said central strand is Wa Lin and gulps down the formula structure, and it is evenly wrapped by 6 steel wire of internal layer and twists with the fingers the core wire outside, is made up of 6 finer wires and 12 thick wire steel wire of internal layer.

Said central strand is 1 strand.

Said internal layer thigh is 8 strands.

Said outer layer strand is 8 strands, per sharely evenly wraps the sth. made by twisting core wire by 9 steel wire of internal layer, and 9 cover wires evenly wrap to be twisted with the fingers steel wire of internal layer and form.

The beneficial effect of the utility model is: the section of steel wire shape after compacting of the outer layer strand in the utility model changes; Be the face contact between the steel wire; The bulkfactor that this has just increased steel wire rope makes the rank street area of steel wire rope improve, and the whole rope rupture pull force of steel wire rope improves; Steel wire rope poker after compacting is even, has shock resistance preferably and antiwear property; Because deformation has taken place the outer layer strand after the compacting, itself and traction sheave contact area increase, and have resistance preferably and revolve performance.

The specific embodiment

As shown in Figure 1, the utility model provides a kind of load-carrying compacted steel wire rope for elevator, and it comprises central strand, internal layer thigh and outer layer strand.

It is as shown in Figure 2.Said outer layer strand per sharely is made up of cover wire, steel wire of internal layer and core wire, is the Xi Lushi structure, after compacting, is the face contact between the steel wire;

Preferably, said outer layer strand is 8 strands, per sharely evenly wraps the sth. made by twisting core wire by 9 steel wire of internal layer, and 9 cover wires evenly wrap to be twisted with the fingers steel wire of internal layer and form

As shown in Figure 3, said internal layer thigh, it evenly wraps the sth. made by twisting core wire by 6 steel wires and forms;

As shown in Figure 4, said central strand is Wa Lin and gulps down the formula structure, and it is evenly wrapped by 6 steel wire of internal layer and twists with the fingers the core wire outside, is made up of 6 finer wires and 12 thick wire steel wire of internal layer.

Said central strand is 1 strand.

Said internal layer thigh is 8 strands.

Obviously, the foregoing description only be for explanation clearly done for example, and be not qualification to embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all embodiments.And conspicuous variation of being extended out thus or change still are among the protection domain of the invention.
