Abstract
The invention provides a lift cable with a steel wire bearing cable core and relates to the technical field of cables. The lift cable comprises a steel wire, an inner sheath, a plurality of threads of bundled naked copper wire conductors, a core wire insulating layer, a non-woven layer, a loading layer and an outer sheath, wherein the inner sheath is arranged outside the steel wire and the plurality of threads of the bundled naked copper wire conductors with the core wire insulating layer are stranded into a cable by taking a steel wire loading core cable as the center; the non-woven layer covers the plurality of threads of the bundled naked copper wire conductors, the outer sheath is arranged outside the non-woven layer, and the loading layer is arranged between the non-woven layer and the outer sheath. The lift cable adopts the steel wire bearing cable core and a textile protective braided layer, so that the lift cable can be suspended and used in a long length and the service life of the cable is prolonged.
Description
Technical field
The present invention relates to the cable technology field, be specifically related to a kind of elevator cable that carries cable core with steel wire.
Background technology
Elevator is the requisite equipment of riding instead of walk in the skyscraper, frequent moving up and down, for elevator provides the cable of working power also inevitable along with it moves up and down.For this reason, the traditional cable line is because design is reasonable inadequately, and is relatively poor because of its pull resistance in lifting process repeatedly, after longer regular elevating movement, fracture might occur, brings the interruption of outage or other correlation function.
Summary of the invention
The purpose of this invention is to provide a kind of elevator cable with steel wire carrying cable core, its adopts steel wire to carry cable core and yarn fabric protection braid, but length hangs use, has prolonged the useful life of its cable.
In order to solve the existing problem of background technology; The present invention adopts following technical scheme: a kind of elevator cable that carries cable core with steel wire; It comprises that steel wire, inner sheath, multiply carefully are twisted into the thin bare copper wire conductor of bundle, core insulation layer, nonwoven layers, bearing bed and oversheath; Said steel wire is provided with inner sheath outward, and it is the stranded stranding in center with steel wire carrying cable core that the said multiply that has the core insulation layer carefully is twisted into the thin bare copper wire conductor of bundle, and said multiply carefully is twisted into the thin bare copper wire conductor of bundle and is coated with nonwoven layers; Said nonwoven layers is provided with oversheath outward, and between nonwoven layers and oversheath, is provided with bearing bed.
As improvement, said core insulation layer is a PVC compound core insulation layer.
As improvement, said nonwoven layers is a nonwoven material layer.
As improvement, said bearing bed is a textile fabric interlacing bearing bed.
As improvement, said oversheath is a PVC compound oversheath.
The present invention has following beneficial effect: take steel wire to carry cable core, can grow the distance suspension and use; Textile fabric interlacing bearing bed and PVC compound oversheath have guaranteed the flexibility of cable to strengthen its pull resistance at low temperatures, make in the elevating movement process, not to be prone to phenomenon of rupture.In a word, this elevator cable adopts steel wire to carry cable core and yarn fabric protection braid, has satisfied length suspension instructions for use, has prolonged its useful life.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
With reference to Fig. 1; This embodiment adopts following technical scheme: a kind of elevator cable that carries cable core with steel wire; It comprises that steel wire 1, inner sheath 2, multiply carefully are twisted into the thin bare copper wire conductor of bundle 3, core insulation layer 4, nonwoven layers 5, bearing bed 6 and oversheath 7; The said steel wire 1 outer inner sheath 2 that is provided with, it is the stranded stranding in center with steel wire 1 carrying cable core that the said multiply that has core insulation layer 4 carefully is twisted into the thin bare copper wire conductor 3 of bundle, said multiply carefully is twisted into the thin bare copper wire conductor 3 of bundle and is coated with nonwoven layers 5; Be provided with oversheath 7 outside the said nonwoven layers 5, and between nonwoven layers 5 and oversheath 7, be provided with bearing bed 6.
Said core insulation layer 4 is a PVC compound core insulation layer.
Said nonwoven layers 5 is a nonwoven material layer.
Said bearing bed 6 is a textile fabric interlacing bearing bed.
Said oversheath 7 is a PVC compound oversheath.
