Description
Technical field
The present invention relates to field of cable technology, particularly relate to a kind of elevator flat cable.
Background technology
Cable is the carrier of electric power conveying, its use scenes is boundless, also make in different application scenarioss also not identical to the requirement of cable performance, particularly under the environment of elevator use, existing cable is in use faced with problems, and the mechanical stress of such as bearing is little, in suspension and bending process, cable is easily stretched or disconnected core occurs, and affects the useful life of cable and the stable of Signal transmissions.The problems referred to above need improvement badly.
Summary of the invention
For solving the technical problem existed in background technology, the present invention proposes the elevator flat cable that a kind of tension is withstand voltage, be applicable to long distance suspension.
A kind of elevator flat cable that the present invention proposes, comprises many cables and flat sheath;
Many cables are spaced parallel longitudinal in flat sheath, and the axis of all cables is in the same plane, the polyester fiber reinforced layer that cable comprises cable core, is coated on the lapping layer of cable core outside, is coated on lapping layer outside;
Cable core comprises multiple conducting wires and a flexible core, and multiple conducting wires is stranded around a flexible core, and wire comprises the conductor in the middle part of being positioned at, is coated on the insulating barrier of conductor outside, is coated on the screen of insulating barrier outside;
Also be provided with two first strengthening cores and Duo Gen second strengthening core in flat sheath, two first strengthening cores lay respectively at many cable both sides and arrange vertically, and many second strengthening cores are parallel longitudinal, and every root second strengthening core is between adjacent two cables.
Preferably, the tensile strength of the first strengthening core is greater than the tensile strength of the second strengthening core.
Preferably, the first strengthening core and the second strengthening core form by many steel wires are stranded.
Preferably, the cable of the second adjacent both sides of strengthening core is equal with the distance between the second strengthening core.
Preferably, the axis of the first strengthening core and the axis of the second strengthening core in the same plane.
Preferably, flexible core has axial through hole.
The elevator flat cable that the present invention proposes; on the one hand; flat sheath and polyester fiber reinforced layer at outside guardwire, can improve the intensity of cable, on the other hand; flexible core on wire can by deformation from internal protection wire; further enhancing the intensity of cable, more on the one hand, the first strengthening core that flat sheath is arranged and the second strengthening core; improve the mechanical strength of sheath, thus improve the intensity of cable further.By the combination of said structure, enhance tension and the withstand voltage properties of cable greatly, make cable not easily be stretched in the course of the work or disconnected core occurs, its long service life, stable signal transmission.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of elevator flat cable that the present invention proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of elevator flat cable that the present invention proposes.
With reference to Fig. 1, the present invention proposes a kind of elevator flat cable, comprises many cables and flat sheath 1;
Many cables are spaced parallel longitudinal in flat sheath 1, and the axis of all cables is in the same plane, the polyester fiber reinforced layer 5 that cable comprises cable core, is coated on the lapping layer 4 of cable core outside, is coated on lapping layer 4 outside;
Cable core comprises multiple conducting wires 2 and a flexible core 3, and multiple conducting wires 2 is stranded around a flexible core, and wire 2 comprises the conductor 21 in the middle part of being positioned at, is coated on the insulating barrier 22 of conductor 21 outside, is coated on the screen 23 of insulating barrier 22 outside;
Also be provided with two first strengthening cores 6 and Duo Gen second strengthening core 7, first strengthening core 6 and the second strengthening core 7 in flat sheath 1 to form by many steel wires are stranded.Two first strengthening cores 6 lay respectively at many cable both sides and arrange vertically, and many second strengthening cores 7 are parallel longitudinal, and every root second strengthening core 7 is between adjacent two cables.
In such scheme; on the one hand; flat sheath 1 and polyester fiber reinforced layer 5 at cable core outer protection wire 2, can improve the intensity of cable, on the other hand; flexible core 3 on cable core can by deformation from cable core internal protection wire 2; further enhancing the intensity of cable, more on the one hand, the first strengthening core 6 and the second strengthening core 7 that flat sheath 1 is arranged; improve the mechanical strength of sheath, thus improve the intensity of cable further.
Due to cable in use, play the pressure that the stress that is subject to of both sides is subject to relative to middle part large, in order to protect cable both sides not to be torn, the tensile strength of the first strengthening core 6 is greater than the tensile strength of the second strengthening core 7.
The cable of the second adjacent both sides of strengthening core 7 is equal with the distance between the second strengthening core 7, the axis of the first strengthening core 6 and the axis of the second strengthening core 7 in the same plane, this structural design is more reasonable, and when cable is subject to external stress, each cable core is stressed more even.
Flexible core 3 has axial through hole, alleviates the weight of cable, and provides certain cushion space for the deformation of flexible core 3.
The elevator flat cable that the present invention proposes, utilizes the design of multistage tension pressure-resistance structure, protects wire from the inside to the outside; enhance tension and the withstand voltage properties of cable greatly; cable is made not easily to be stretched in the course of the work or disconnected core occurs, its long service life, stable signal transmission.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
