Description
Technical field
The utility model is related to a kind of traction rope, particularly 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 respectively independent each other.
The sub-thread traction rope that elevator uses is in the traction slot for entering traction wheel, since the effect of the frictional force of trough rim causes
Rope occurs rolling phenomenon in traction slot, and resulting shearing force leads to restrict silk by failure by shear, fracture of wire phenomenon occurs, lead
The service life of messenger is affected,
At the same time the relative friction of traction rope and traction slot makes traction rope be worn with traction slot, reduces traction
The service life of rope, traction slot.
Sub-thread traction rope and effective contact area of traction slot can not be effectively improved by the structural restriction of sub-thread traction rope,
So that transmission efficiency can not effectively improve, system energy consumption is caused not reduce effectively.
For the lifting capacity of hoisting elevator, mainstream way is to increase the rugosity of traction rope, however traction rope is passing through rope
During wheel, traction rope will flexural deformation, crimp, tensile stress during flexural deformation with the nearly rope sheave point of rope silk in section is less than
The tensile stress of remote rope sheave point, diameter of section is bigger, and the stress-deviation of point-to-point transmission is bigger, that is, Tensile stress influence of restricting causes to lead
The fatigue damage deviation of rope silk is bigger inside messenger.Crimp is that the rope silk of the remote rope sheave point in same section passes through adjacent rope silk
Gradually lead to the process of traction rope deformation to the extruding of nearly rope sheave point, at this point, the mutual displacement inside traction rope between rope silk will produce
Raw frictional force abrasion rope silk, leads to silk fracture of restricting, traction rope diameter of section is bigger, and extrusion deformation degree is bigger, restricts inside traction rope
The abrasion of silk is bigger, and rope silk phenomenon of rupture is more serious, and the service life of traction rope is shorter.
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, greatly increases the contact area of traction rope and traction slot, increases frictional force, so as to improve mechanical efficiency, extend traction rope,
The service life of traction slot.
Technical solution is used by the utility model：
One kind including at least two traction main bodys and connects adjacent traction main body in dumb-bell shape elevator traction rope
Connector, connection external surface are seamlessly transitted with traction body outer surface.
By said program, the traction main body includes load main body and is wrapped in the wrapping layer of load body surfaces, package
Layer is seamlessly transitted with connector circular arc.
By said program, the traction main body section is rounded, and each diameter for drawing main body is identical.
By said program, the traction main diameter D1With adjacent traction main center spacing L1Proportionate relationship be L1=
1.5D1。
By said program, the thickness L of the connector thinnest part2=0.3D1。
By said program, the connector and wrapping layer are made of polyurethane.
By said program, the load main body is by the spiral circular fiber rope of synthetic fibre tows stock twisting,Including in
Heart rope strand, the center rope strand periphery is provided with forms the first rope strand layer by more first rope strands, and the first rope strand is and axial cord
Stock is tangent, and tangent contact between adjacent first strands, the first rope strand layer periphery are provided with by more second rope strands and third rope
Second rope strand layer of stock composition, second rope strand and third rope strand interlaced arrangement, and the second adjacent rope strand and third rope strand
Tangent contact, the second rope strand and third rope strand are tangent with the first rope strand, and the second rope strand is different from third strand diameter, the second rope
Stock layer periphery is provided with the peripheral rope strand layer being made of more 4th rope strands, the 4th rope strand simultaneously with third rope strand and the
The tangent contact of two rope strands.
The utility model advantageous effect is：
1st, 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
Core component, its outer surface to performance are also effectively increased outer surface contact with traction slot of two cordage inclusion enclaves
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 cause it is bifilar in it is any one all can not with traction slot trough rim occur relative motion, so as 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；
2nd, since connector increases frictional force, so as to improve transmission efficiency；
3rd, using more traction main bodys, the failure by shear of single traction main body is reduced, extends service life；
4th, the load main body of traction rope forms wrapping layer by polyurethane gluing, by load main body " lock ring " together, leads
Draw main body to be unlikely to deform；
5th, every layer of every tow stock is contacted with the equal line of tow stock of surrounding, compact structure, and cross sectional shape is stablized, and is had suitable
Anti-extrusion ability；
6th, the diameter of traction rope main body and the specific proportions relationship and connector of Liang Gen traction ropes main center spacing are thick
Proportionate relationship is spent, in suitable ratio range, traction rope is made to be in the range of approrpiate wts, stability is optimal, service life
It is longer.
