Description

For the open rope for being lifted

Technical field

This utility model be related to it is a kind of used in lift system or as in drive system control cable rope, The drive system such as window elevator systems.

Background technology

Various high-caliber standards must are fulfilled for for the rope in lift system or in window elevator systems.These Rope must have the longer life time, because they are repeatedly bent, and these ropes must be anticorrosive, because they are logical Chang Bixu is operated in erosion environment condition.

Rope on the basis of has following structure in the industry：19+8 × 7, it means that the core strand line of 19 steel wires with And eight strands of respective seven steel wires.

Utility model content

Main purpose of the present utility model is to provide a kind of optional rope, and the rope is than 19+8 × 7 rope structure more just Preferably.

Another object of the present utility model is to provide a kind of rope with the longer life time.

Another object of the present utility model is to provide a kind of rope, and the rope has for thermoplastic or elastomer There is good permeability.

According to first aspect of the present utility model, there is provided a kind of to be used in lift system or be used for drive system for example Rope in window elevator systems.The rope includes the layer strand of core strand line and only seven.This seven layer strands are around core Strand is twisted, and forms the unsaturated layer around core strand line.

Term " unsaturated layer " refers to the layer around core strand line, wherein, elastomer or polymer can be in normal extrusion works Permeate during skill.

The diameter of core strand line can be reduced using the layer strand of only seven, while reducing the number of strand twining steps. In such manner, it is possible to make less expensive rope.

Formation around the unsaturated layer of core strand line enables to thermoplastic or elastomer penetration.This infiltration has three Weight effect.First, will be rope machinery earth anchor solid in thermoplastic or elastomer.Secondly, except on silk via rope The corrosion protection that provides of each coating, thermoplastic or elastomer additionally provide the corrosion protection for rope.3rd, in behaviour In work, thermoplastic or elastomer are as a kind of cushion pad between two adjacent layer strands, therefore avoid or extremely The abrasion of two adjacent strands is alleviated less.

In the preferred embodiment of this utility model first aspect, at least one layer strand (most preferably whole layer strands) A steel wire and the six roots of sensation steel wire around steel wire twisting including the core as layer strand.

In order to further increase the penetration degree of polymer or elastomer, most preferably, a steel wire has a diameter D3, each own identical silk diameter d4 of the six roots of sensation steel wire, and d4 is less than d3, to produce the insatiable hunger around a steel wire And layer.Difference between d3 and d4 is preferably greater than 0.01mm.Due to the unsaturated layer in layer strand, thus polymer or Elastomer is not only permeated between layer strand, is also infiltrated into inside layer strand.In addition, because according to this utility model by reducing Gauge of wire in the layer is come unsaturation layer as realizing, and these steel wires are outside positioned at the footpath of the cross section of rope Silk at side, therefore the life time increase of rope, this is because the bending stress ratio produced in filament is produced in crin Bending stress it is less.

According to the preferred embodiment of first aspect, core strand line have three steel wires of the core as core strand line and around this three Nine steel wires of root steel wire twisting.

In order to further improve the penetration degree of polymer or elastomer, most preferably, three steel wires have diameter d1, Nine steel wires have diameter d2, and d2 is less than d1, to produce the unsaturated layer around three steel wires.Preferably, Difference between d1 and d2 is more than 0.01mm.Due to the unsaturated layer in core strand line, polymer or elastomer are also infiltrated into In core strand line.

Following structure is had according to the preferred embodiment of the rope of this utility model first aspect：3×d1+9×d2+7× (1×d3+6×d4)。

Preferably, silk diameter d3 is less than or equal to d1, more than or equal to d2.
