Abstract
The utility model discloses a resistant crooked for elevator flat cable of high strength, including the same equidistant cable core that directly drags side by side of a plurality of group's structures, its cable core forms at its central reinforcing element and around many insulation core transposition outside the reinforcing element by setting up, the outer directly crowded package outer jacket of cable core, both ends were equipped with the tensile component about wai hu was intraformational, were equipped with a plurality of semicircular groove in the outer jacket outer fringe, and semicircular groove locates the intermediate position department between the adjacent cable core of per 2 groups, insulation core comprises conductor and the insulating layer of crowded package outside the conductor. The utility model discloses simple structure has very high mechanical strength and good flexibility ability, can effectively solve elevator cable easy problem of breaking the core under frequent crooked environment, still can prolong the life of elevator cable.
Description
Technical field
This utility model relates to elevator cable field, is specifically related to a kind of high intensity resist bending elevator flat cable.
Background technology
Elevator cable is the important matching component of elevator, need to move up and down along with elevator, and in the process, elevator cable should bear deadweight, bears the stress that U-bend produces frequently again.Along with skyscraper gets more and more, elevator runs increasingly faster, and traditional elevator cable can not meet the service requirement of present elevator, it is easy to occur disconnected core, outer jacket problems of crack, and once disconnected core, fault of stop will occur, need whole replacing, repair fairly cumbersome.
Utility model content
Technical problem to be solved in the utility model is for the deficiencies in the prior art, it is provided that a kind of manufacture method is simple, performance good and the elevator flat cable of high life.
The utility model discloses a kind of high intensity resist bending elevator flat cable, including the cable core that some groups of structure phase equal pitch directly drag side by side, its cable core is to be formed by the reinforcing element being disposed therein the heart and many insulated wire cores being centered around outside reinforcing element are stranded；Directly extruding outer jacket outside cable core, the two ends, left and right in outer jacket are provided with tensile elements, and outer jacket outer rim is provided with several semi-circular recesses, and semi-circular recesses is located at the middle position between every 2 groups of adjacent cable cores；Described insulated wire cores is made up of conductor and the insulating barrier being extruded in outside conductor.
In this utility model, it is preferable that described conductor is that many soft copper tow strands form, copper wire percentage elongation 20%-30%, bundle strand lay ratio 10-15 times.
In this utility model, it is preferable that it is consistent that described insulated wire cores direction of lay twists direction with conductor bundle.
In this utility model, it is preferable that described insulating barrier is made up of PVC butyronitrile elastomer.
In this utility model, it is preferable that described tensile elements is to form steel wire rope for 19 finer wire twisteds, and its nominal diameter is 1.0-3.5mm.
In this utility model, it is preferable that described outer jacket is made up of sheath level PVC butyronitrile elastomer.
In this utility model, it is preferable that described semi-circular recesses is upper and lower symmetrical structure.
The beneficial effects of the utility model are in that:
It is reinforcing element that this utility model have employed aramid yarn, aramid yarn strength high toughness light weight good, soft, can bear the stress produced when cable is frequently bended, effectively prevent cable core break；Adopting flexible steel cable as tensile elements, its stretching resistance can bear more than 50 times of cable deadweight, makes cable have superpower resistance to tension；Outer jacket outer rim arranges semi-circular recesses, the horizontal mechanical stress that when can effectively alleviate cable U-bend, outer jacket is subject to, and enhances resist bending and the anti-wear performance of protective coverings of cable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments this utility model done and further illustrate.
As shown in Figure 1, a kind of high intensity resist bending elevator flat cable described in the utility model, concrete structure is: include the cable core that some groups of structure phase equal pitch directly drag side by side, and its cable core is to be formed by the reinforcing element being disposed therein the heart and many insulated wire cores being centered around outside reinforcing element are stranded；Directly extruding outer jacket 6 outside cable core, the two ends, left and right in outer jacket 6 are provided with tensile elements 5, and outer jacket 6 outer rim is provided with several semi-circular recesses 4, and semi-circular recesses 4 is located at the middle position between every 2 groups of adjacent cable cores；Described insulated wire cores is made up of conductor 1 and the insulating barrier 2 being extruded in outside conductor 1.
Described conductor 1 forms for many soft copper tow strands, copper wire percentage elongation 20%-30%, bundle strand lay ratio 10-15 times, improves mechanical strength and the resistance to bend(ing) of conductor.
It is consistent that described insulated wire cores direction of lay twists direction with conductor bundle, improves the flexibility of cable.
Described insulating barrier 2 is made up of PVC butyronitrile elastomer, can be not only used for the electric insulation layer of conductor, can be used for again the protective layer of reinforcing element, and this material softness is good, and mechanical strength is high, can improve cable service life.
Described tensile elements 5 is the steel wire rope of 19 finer wire twisteds, and its nominal diameter is 1.0-3.5mm, conduct oneself with dignity up to cable more than 50 times of steel wire rope pull-off force, and flexibility is fine, makes cable have superpower resistance to tension.
Described semi-circular recesses 4 is located at the centre position of every 2 groups of adjacent cable cores, the horizontal mechanical stress that when can effectively alleviate cable U-bend, outer jacket is subject to, and enhances resist bending and the anti-wear performance of protective coverings of cable.
Described outer jacket 6 is made up of sheath level PVC butyronitrile elastomer, and this mechanical strength is high, flexibility is good and wear-resisting, oil resistance is excellent, and cable service life can be greatly improved.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
