Description
Technical field
The present invention relates to a kind of pull rope, particularly a kind of elevator pull rope.
Background technology
Elevator has penetrated into many corners of people's life, and elevator traction rope is the important component of elevator device, electricity
The capability and performance of terraced pull rope directly affects the safety coefficient of elevator, and existing elevator traction rope is all single cord, even more
Strand is also each independent each other.
The A of Publication No. CN 105369657 Chinese invention patent discloses a kind of elevator pull rope of new structure,
Its structure includes center rope strand, the peripheral rope strand positioned at center rope strand periphery, peripheral rope strand axis and center rope strand diameter parallel,
And each peripheral rope strand axis is equal to center rope strand axial line distance, the wire rope core of peripheral rope strand and center rope strand is Steel cord,
Steel cord periphery one layer of carbon fiber of cladding.The invention periphery rope strand is arranged in parallel in the periphery of center rope strand, and its axis is with
The diameter parallel of heart rope strand, and the axis of every peripheral rope strand is equal with the axial line distance of center rope strand, can pass through pull rope
During the grooving of traction rope sheave, rotation power is not produced inside pull rope, is avoided because the effect of rotation power makes pull rope outer surface
The first cladding shear, and cause the too fast fracture by fatigue of the first cladding and destroy pull rope performance, extend
The service life of pull rope, ensure the safe for operation of elevator.
But the structure is not fine and close enough between each rope strand of above-mentioned patent, and anti-extrusion ability is weaker.
The content of the invention
The technical problems to be solved by the invention are overcome the deficiencies in the prior art, there is provided a kind of novel elevator traction
Rope, its compact structure, anti-extrusion ability are strong, it is ensured that do not produce rotation power inside pull rope, the rope silk prevented in pull rope is cut
The phenomenon that shear force destroys, it can effectively extend the service life of pull rope.
The technical solution adopted in the present invention is：
A kind of novel elevator pull rope, including traction main body, the traction main body include rope strand and are coated on outside rope strand
The cladding enclosed, the rope strand include center rope strand, and the center rope strand periphery is provided with forms first by more first rope strands
Rope strand layer, the first rope strand with center rope strand is tangent contacts, and tangent contact between adjacent first strands, the first rope strand layer periphery
It is provided with the second rope strand layer being made up of more second rope strands and the 3rd rope strand, second rope strand and the 3rd rope strand interlock cloth
Put, and the second adjacent rope strand and the 3rd tangent contact of rope strand, the second rope strand and the 3rd rope strand with the first rope strand is tangent contacts,
Second rope strand is different from the 3rd strand diameter, and the second rope strand layer periphery is provided with the peripheral rope strand being made up of more 4th rope strands
Layer, the 4th rope strand simultaneously with the 3rd rope strand and the second rope strand is tangent contacts, each rope strand axis of each rope strand layer with
Center rope strand helically arrange by wire.
By such scheme, tangent contact between adjacent 4th rope strand.
By such scheme, a diameter of D1 of center rope strand, the first strand diameter is D2, and the second strand diameter is D3, and the 3rd restricts
The a diameter of D4 of stock, the 4th strand diameter is D5, it is assumed that benchmark rugosity isEach strand diameter and benchmark rugosityRatio about
For：
By such scheme, the 3rd rope strand layer, the 4th rope strand are additionally provided between the second rope strand layer and peripheral rope strand layer
Layer N rope strand layers, the homogeneous cut-grafting of rope strand of each rope strand layer is touched, and in adjacent two rope strands layer, one layer the same as the first rope strand layer knot
Structure, for another layer with the second rope strand Rotating fields, N is even number.
By such scheme, the rope strand is aramid fiber, shaped to be made, the synthetic fibers Kang La Qiang Du≤
2000MPa。
By such scheme, the traction main body comprises at least two, is connected between adjacent traction main body by connector, even
It is in integrative-structure that junctor is connected with cladding, and the thickness of the connector is less than strand diameter, and the connector is in cladding
Circular arc seamlessly transits.
By such scheme, the connector and inclusion enclave with polyurethane into.
By such scheme, the first rope strand layer is made up of the rope strand of the six roots of sensation first, and the second rope strand layer is restricted including the six roots of sensation second
Stock and the rope strand of the six roots of sensation the 3rd, the 3rd rope strand layer are made up of 12 the 4th rope strands.
Beneficial effect of the present invention is：
1st, the strand structure of pull rope is fine and close, and each rope strand is strong with other rope strand linear contact lays of surrounding, anti-extrusion ability, it is ensured that
Rotation power is not produced inside pull rope, prevents the phenomenon that the rope silk in pull rope is destroyed by shearing force, extends making for pull rope
Use the life-span.
2nd, the rope strand of pull rope uses synthetic fibres, and compared with steel wire, the proportion of synthetic fibres is steel wire proportion
1/4, tensile stress is 5 times of steel wire.With the elevator traction rope system that synthetic fibres are crafted than steel wire elevator traction rope system
Deadweight is lighter, driving power is stronger, energy consumption is lower.
3rd, the connector of pull rope not only enables the cross-sectional stability of bifilar pull rope side by side good or pull rope tool is led
Core component, its outer surface to performance are also effectively increased outer surface contact with traction groove of two cordage inclusion enclaves
Area；Pull rope guider is provided with before traction groove, its effect is that pull rope is accurately imported to traction groove, is eliminated simultaneously
Pull rope is rocked, and bifilar pull rope side by side is accurately made a gift to someone after traction groove, even if being acted on by trough rim frictional force, it is bifilar simultaneously
The dumbbell shape structure of row pull rope cause it is bifilar in it is any one all can not with traction groove trough rim occur relative motion, so as to disappear
Except the rolling phenomenon in groove of restricting so that rope silk is no longer influenced by the destruction of shearing force, at the same time also eliminates pull rope, drags
The abrasion of approaching channel, extend pull rope, the service life of traction groove；
4th, because connector adds frictional force, transmission efficiency is improved；
5th, the load main body of pull rope forms integument by the way that polyurethane is glued, by load main body " lock ring " together, no
It is yielding.
