Abstract
The invention discloses a reinforced type bending-resistant flat control cable. The reinforced type bending-resistant flat control cable comprises a flat outer sheath, wherein three rhombic holes and two circular holes are formed in the outer sheath; control wire cores with the same number are arranged in each rhombic hole; a tensile element is arranged in each circular hole; a reinforcing element is arranged in each middle core of the multiple control wire cores separately; a plurality of semicircular grooves are formed in the outer edge of the outer sheath; and the semicircular grooves are formed in the middle positions between every two groups of adjacent cable cores. The reinforced type bending-resistant flat control cable is simple in structure, quite high in mechanical strength and bending resistance, capable of effectively solving the problem that the core of an elevator cable is broken easily in a frequent bending environment, and also capable of prolonging the service life of the elevator cable.
Description
Technical field
The present invention relates to elevator cable field, and in particular to a kind of reinforced resist bending flat controls cable.
Background technology
Elevator cable is the important matching component of elevator, need to be moved up and down with elevator, and in the process, elevator cable was both
Deadweight is born, the stress that frequently U-bend is produced is born again.As skyscraper is more and more, elevator operation is more next
Faster, traditional elevator cable can not meet the service requirement of present elevator, it is easy to disconnected core, outer jacket cracking etc. occur and asks
Topic, once and disconnected core, fault of stop will occur, need whole replacing, repair fairly cumbersome.
The content of the invention
The technical problem to be solved is for the deficiencies in the prior art, there is provided a kind of simple structure, performance
The reinforced resist bending flat control cable of good and high life.
The invention discloses a kind of reinforced resist bending flat controls cable, including flat oversheath, it is provided with oversheath
Three diamond holes and two circular holes；The same number of control conductor is provided with each diamond hole, is provided with anti-in each circular hole
Draw element；The SMIS of many control conductors is provided with reinforcing element；Oversheath outer rim is provided with several semi-circular recesses, semicircle
Groove is located at per the middle position between 2 groups of adjacent cable cores.
In the present invention, it is preferable that the control conductor is made up of copper conductor and the inhibiting tape being extruded in outside copper conductor.
In the present invention, it is preferable that the reinforcing element is by centrally disposed steel core and the aramid yarn being extruded in outside steel core
Constitute.
In the present invention, it is preferable that the tensile elements are the aluminum rope of 36 thin aluminium wire twisteds, its nominal diameter is 2-
6mm。
In the present invention, it is preferable that described outer jacket is made up of sheath level PVC butyronitrile elastomer.
In the present invention, it is preferable that described semi-circular recesses are in upper and lower symmetrical structure.
The beneficial effects of the present invention is：
Present invention employs aramid yarn is reinforcing element, and aramid yarn strength high toughness is good, soft light weight, can bear cable frequently curved
The stress produced when bent, effectively prevent cable core break；Using flexible steel cable as tensile elements, its stretching resistance can bear cable
More than 50 times of deadweight, make cable have superpower resistance to tension；Outer jacket outer rim arranges semi-circular recesses, can effectively alleviate electricity
The horizontal mechanical stress that outer jacket is subject to during cable U-bend, enhances the resist bending and anti-wear performance of protective coverings of cable.In addition,
In order to preferably protect control conductor, oversheath to be provided with three protection holes, prevent control conductor to be subjected to displacement；It is same to arrange two
Circular hole, protects tensile elements, prevents tensile elements to be subjected to displacement.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Specific embodiment
The present invention is done with reference to the accompanying drawings and detailed description further is illustrated.
As shown in figure 1, a kind of reinforced resist bending flat of the present invention controls cable, including flat oversheath 1, outward
Three diamond holes 2 and two circular holes 3 are provided with sheath；The same number of control conductor, the control are provided with each diamond hole
Core processed is made up of copper conductor 4 and the inhibiting tape being extruded in outside copper conductor 5.
Tensile elements 6 are provided with each circular hole, the SMIS of many control conductors is provided with reinforcing element, the reinforcing element
It is made up of centrally disposed steel core 7 and the aramid yarn 8 being extruded in outside steel core；It is semicircle that the outer rim of oversheath 1 is provided with several
Groove 9, semi-circular recesses are located at per the middle position between 2 groups of adjacent cable cores.
Described control conductor is 6, and 6 control conductors and a reinforcing element are stranded in Pedicellus et Pericarpium Trapae by the way of " 1+6 "
In shape hole.
The tensile elements 6 are the steel wire rope of 36 finer wire twisteds, and its nominal diameter is 2-6mm, and steel wire rope draws
Conduct oneself with dignity up to cable more than 70 times of disconnected power, and flexibility is very well, makes cable have superpower resistance to tension.
The semi-circular recesses 9 located at centre position per 2 groups of adjacent cable cores, when can effectively alleviate cable U-bend outside
The horizontal mechanical stress that sheath is subject to, enhances the resist bending and anti-wear performance of protective coverings of cable.
The oversheath is made up of sheath level PVC butyronitrile elastomer, the mechanical strength is high, flexibility is good and wear-resisting,
Oil resistance is excellent, can greatly improve cable service life.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.Clearly each component part not can use prior art to be realized in the present embodiment.
