Description
Technical field
The utility model is related to a kind of traction rope, especially a kind of elevator traction 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 traction rope directly affects the safety coefficient of elevator, and existing elevator traction rope is all single cord, even more
Strand is also separate each other.
The Chinese utility model patent of 105369657 A of Publication No. CN discloses a kind of new structural elevator with leading
Messenger, structure include center rope strand, are located at the peripheral rope strand of center rope strand periphery, peripheral rope strand axis and center rope strand axis
It is 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 wire
Wire rope core, Steel cord periphery coat one layer of carbon fiber.The utility model periphery rope strand is arranged in parallel in the periphery of center rope strand,
Axis is parallel with the axis of center rope strand, and the axis of every peripheral rope strand is equal with the axial line distance of center rope strand, can make to lead
When messenger passes through the grooving of traction rope sheave, rotation power is not generated inside traction rope, the effect due to rotation power is avoided to make traction rope
First covering body of peripheral surface is sheared, and is caused the too fast fracture by fatigue of the first covering body and destroyed the usability of traction rope
Can, extend the service life of traction rope, ensures the operational safety 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.
Utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of novel elevator with leading
Messenger, compact structure, anti-extrusion ability are strong, it is ensured that rotation power is not generated inside traction rope, prevent rope silk in traction rope by
The phenomenon that shearing force is destroyed, can effectively extend the service life of traction rope.
Technical solution used by the utility model is：
A kind of novel elevator traction rope, including traction main body, the traction main body include rope strand and are coated on outside rope strand
The covering body enclosed, the rope strand include center rope strand, and 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 of more second rope strands and third rope strand, second rope strand and third rope strand interlock cloth
Set, and adjacent the second rope strand and the tangent contact of third rope strand, the second rope strand and third rope strand with the first rope strand is tangent contacts,
Second rope strand is different from third strand diameter, and the second rope strand layer periphery is provided with the peripheral rope strand being made of more 4th rope strands
Layer, the 4th rope strand simultaneously with third rope strand and the second rope strand is tangent contacts, each rope strand axis of each rope strand layer with
Center rope strand is helically linear to be arranged.
By said program, tangent contact between adjacent 4th rope strand.
By said program, a diameter of D1 of center rope strand, the first strand diameter is D2, and the second strand diameter is D3, third rope
The a diameter of D4 of stock, the 4th strand diameter are D5, it is assumed that benchmark rugosity isEach strand diameter and benchmark rugosityRatio about
For：
By said program, third rope strand layer, the 4th rope strand are additionally provided between the second rope strand layer and peripheral rope strand layer
The homogeneous cut-grafting of rope strand of layer N rope strand layers, 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 layer structure, N is even number.
By said program, the rope strand is aramid fiber, shaped to be made, the aramid fiber Kang La Qiang Du≤
2000MPa。
By said program, the traction main body includes at least two, is connected by connector between adjacent traction main body, even
It is in integral structure that junctor is connect with covering body, and the thickness of the connector is less than strand diameter, and the connector is in covering body
Circular arc seamlessly transits.
By said program, the connector and inclusion enclave are made of polyurethane.
By said program, the first rope strand layer is made of the first rope strand of the six roots of sensation, and the second rope strand layer includes that the six roots of sensation second is restricted
Stock and six roots of sensation third rope strand, the third rope strand layer are made of 12 the 4th rope strands.
The utility model advantageous effect is：
1, the strand structure of traction rope is fine and close, and other rope strand lines contact each rope strand with surrounding, and anti-extrusion ability is strong, it is ensured that
Rotation power is not generated inside traction rope, prevents the phenomenon that rope silk in traction rope is destroyed by shearing force, extends making for traction rope
Use the service life.
2, the rope strand of traction 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.The elevator traction rope system being crafted with synthetic fibres is than steel wire elevator traction rope system
Dead weight is lighter, driving power is stronger, energy consumption is lower.
3, the connector of traction rope not only enables the cross-sectional stability of bifilar traction rope arranged side by side good or traction rope tool is led
The contact of the outer surface and traction slot of two cordage inclusion enclaves is also effectively increased to the core component of performance, its outer surface
Area；Traction rope guider is provided with before traction slot, effect is that traction rope is accurately imported to traction slot, is eliminated simultaneously
The shaking of traction rope, bifilar traction rope arranged side by side is accurately made a gift to someone after traction slot, even if being acted on by trough rim frictional force, it is bifilar simultaneously
The dumbbell shape structure of row traction rope make it is bifilar in it is any one all can not with traction slot trough rim occur relative motion, to disappear
In addition to the rolling phenomenon in slot of restricting so that rope silk is no longer influenced by the destruction of shearing force, at the same time also eliminates traction rope, drags
The abrasion of approaching channel extends the service life of traction rope, traction slot；
4, since connector increases frictional force, transmission efficiency is improved；
5, the load main body of traction rope forms wrapping layer by polyurethane gluing, together by load main body " lock ring ", no
It is yielding.
