Abstract

The utility model discloses a compacted wire rope for a lift, consisting of outer layer strands, inner layer strands and centre strands, wherein the outer layer strands and the inner layer strands are uniformly arranged in circumference around the centre strands, and are circumferentially arranged in staggered manner, each of the outer layer strands is composed of an outer layer steel wire, an inner steel wire and a centre steel wire, and is formed after being compacted to be a compacted strand; each of the inner layer strands is composed of an outer layer steel wire and a centre steel wire to form a compacted strand; and the centre strands are composed of three strands, and each centre strand is made of ethylene propylene filament in twisting manner. Since a face contact wire rope enables the compression rate of the outer layer strands and the inner layer strands to be 11.7%, the inner steel wire section of the wire rope is changed to improve the density coefficient of the wire rope, the cross section area of the wire rope is improved by 11%, and the breaking force of the wire rope is improved by 10%; the forged wire rope is compact in structure and uniform in whole rod; the impact resistance and the wear resistance of the wire rope are improved, and the service life of the product is prolonged in double.

Description

A kind of compacted steel wire rope for elevator

Technical field

This patent relates to the steel wire rope of new structure, is suitable at a high speed and special elevator car traction main transmission elevating mechanism.

Background technology

At present, the steel wire rope that is adopted on the lift car traction main transmission elevating mechanism, it all is made up of outer layer strand, internal layer thigh and central strand or outer layer strand and the poly-third ethene wire rope core, outer layer strand generally adopts Xi Lushi or the various line contact structures of watt woods, adopts the round wire twisting of different-diameter to form.

When elevator uses, form elevating drive mechanism by steel wire rope, traction sheave, directive wheel and car roof wheel etc. and drive lift car lifting work.

Because the frequent lifting of elevator is used, and makes that the steel wire of steel wire rope outer layer strand is easy to wear, cause fracture of wire and disconnected thigh, shorten the service life of steel wire rope, and bring harm for elevator safety.

The utility model content

The purpose of this utility model provides the compacting steel wire rope of a kind of suitable high speed or special elevator use, and the steel wire rope that solution is commonly used causes fracture of wire and the thigh that breaks, the problem that shortens the service life of steel wire rope because the steel wire of steel wire rope outer layer strand is easy to wear.

The purpose of this utility model is to be achieved through the following technical solutions:

A kind of compacted steel wire rope for elevator is made up of outer layer strand, internal layer thigh and central strand, and outer layer strand and internal layer thigh are even layout around the central strand circumference, are staggered circumferential arrangement between outer layer strand and internal layer thigh;

Described outer layer strand, per sharely form by cover wire, steel wire of internal layer and core wire, outer layer strand is per share through the compacting aftershaping, cover wire, steel wire of internal layer and core wire are that circular steel wire is made the steel wire that the cross section is an abnormity through roll-in, die drawing by the cross section, promptly agree with mutually, form the compacting thigh at each other contact-making surface;

Described internal layer thigh per sharely is made up of cover wire and core wire, and cover wire and core wire are that circular steel wire is made the steel wire that the cross section is an abnormity through roll-in, die drawing by the cross section, promptly agrees with mutually at each other contact-making surface, forms the compacting thigh;

Described central strand is formed by three strands, and per share central strand forms by the poly-third ethene filament twisting.

Described outer layer strand has 8 strands, and the cover wire of described outer layer strand and steel wire of internal layer are respectively 9.

Described internal layer thigh has 6 strands, is per sharely formed by seven steel wire primary twistings, and these seven gauges of wire are identical, and wherein six roots of sensation steel wire is outer, and a steel wire is a core wire.

Central strand is the poly-third ethene wire rope core, forms the poly-third ethene wire rope core of twisted one-tenth by three strands.

Outer layer strand and internal layer thigh adopt roll-in or die drawing moulding process to process, and make steel cord structure become facial-contracted wire rope.

Outer layer strand and internal layer thigh close rope after adopting the moulding of compacting thigh, outer layer strand and internal layer thigh close rope after adopting the moulding of compacting thigh, the synthetic steel wire rope forges by the axle formula high frequency rotation equipment of forging, make steel wire rope rotation forge 4 tups continuous strike, the extruding under carry out radially compacting, the inner wire cross section of steel wire rope is changed, play the steel wire rope that reaches specified diameter by continuous many hammering reserving diameter parts.

Take such scheme, have the following advantages:

Because it is 11.7% that the facial-contracted wire rope of this patent makes outer layer strand and internal layer thigh compression ratio, steel wire rope inner wire cross section is changed, increase the bulkfactor of steel wire rope, make the cross-sectional area of steel wire rope improve 11%, the whole rope rupture pull force of steel wire rope improves 10%, and steel wire rope structure after forging is tight, and poker is even, improve steel wire rope shock resistance and antiwear property, and prolong product service life at double.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is a kind of structure chart of compacted steel wire rope for elevator.

Among the figure: 1, outer layer strand; 2, internal layer thigh; 3, central strand; 11, cover wire; 12, steel wire of internal layer; 13, core wire; 14, cover wire; 15, core wire.

The specific embodiment

As shown in Figure 1, a kind of compacted steel wire rope for elevator of this patent, form by outer layer strand 1, internal layer thigh 2 and central strand 3, outer layer strand 1 and internal layer thigh 2 are even layout around central strand 3 circumference, 2 on outer layer strand 1 and internal layer thigh are staggered circumferential arrangement, wherein outer layer strand 1 is made up of stereotyped writing, per share again by nine cover wires 11, nine steel wire of internal layer 12 and a core wire 13 are formed, and the diameter of cover wire 11 and core wire 13 is identical and be thick wire, and steel wire of internal layer 12 diameters are more much smaller than the diameter of cover wire 11 and core wire 13.

Described outer layer strand 1, per sharely form by cover wire 11, steel wire of internal layer 12 and core wire 13, outer layer strand 1 is per share through the compacting aftershaping, cover wire 11, steel wire of internal layer 12 and core wire 13 are that circular steel wire is made the steel wire that the cross section is an abnormity through roll-in, die drawing by the cross section, promptly agree with mutually, form the compacting thigh at each other contact-making surface;

Described internal layer thigh 2, per sharely form by cover wire 14 and core wire 15, cover wire 14 and core wire 15 are that circular steel wire is made the steel wire that the cross section is an abnormity through roll-in, die drawing by the cross section, promptly agree with mutually at each other contact-making surface, form the compacting thigh, per sharely formed by seven steel wire primary twistings, these seven gauges of wire are identical, wherein six roots of sensation steel wire is outer, and a steel wire is a core wire;
