Abstract

The utility model discloses a flat polyvinyl chloride insulating lift cable, belonging to the cable technical field, which comprises a flat outer sheath, and twenty-six control line cores, a grounding line core and two twisted pair mask signal lines which are arranged in the outer sheath. Twenty-four of the control line cores are uniformly divided into two groups, each group of twelve control line cores are uniformly divided into three bunches, after four control line cores are twisted into a bunch, each bunch is distributed on one side in the outer sheath in parallel, the two groups of control line cores on the two sides in the outer sheath are distributed symmetrically, and the rest two control line cores are twisted into a cable bunch, and are arranged between the two groups of control line cores together with the grounding line core and the two twisted pair mask signal lines. When the utility model moves along with the lift vertically, the deformation of the inner side and the outer side of the bending position of the cable is small, the cable can bear more bending, and thereby the operation is reliable; the pulling force is distributed uniformly inside the cable, and thereby the overall tensile strength is large; the utility model is bending resistant, has long service life, and thereby can be applied to a high-speed lift.

Description

Flat PVC insulated lift cable

Technical field

The utility model relates to a kind of cable, the cable that particularly a kind of elevator uses.

Background technology

Elevator cable of the prior art, generally its section is rounded, its tension and warping resistance scarce capacity, especially warping resistance ability, because its control signal wire is more, makes that the diameter of cable is bigger, when bending, be positioned at the inboard pressurized of bending part, the outside of bending part is subjected to pulling force simultaneously, satisfy it and have less radius bend, certainly will require all have bigger deformability in the inboard and the outside of bending part, cause agingly and damaged easily like this, useful life is short.

The utility model content

The purpose of this utility model provides a kind of Flat PVC insulated lift cable, makes it have good warping resistance ability, long service life.

The purpose of this utility model is achieved in that Flat PVC insulated lift cable, comprise that section is pancake oversheath, be provided with 20 six roots of sensation control core in the oversheath, a ground connection core and two pair twist shielded signal wire, wherein 24 control cores are divided into two groups, control cores by 12 for every group and be divided into three beams, after being twisted into bundle, every Shu Yousi root control core is distributed in the interior side of oversheath side by side, two groups of both sides control cores are symmetrically distributed in the oversheath, remains two control cores and are twisted into bunch of cables and ground connection core and two pair twist shielded signal wire and are set up in parallel at above-mentioned two groups and control between the cores.

Because overall appearance of the present utility model is pancake, little when it moves up and down with elevator in the interior outside distortion of cable bending part, to compare with the cable of circle, the utility model can tolerate more times bending, uses more reliable; Because control core, ground connection core and pair twist shielded signal wire in the oversheath become symmetery to distribute substantially, make the pulling force basically identical that the utility model left and right sides is subjected to, suffered pulling force distributes at the cable internal balance, make its whole tensile strength big, the utility model warping resistance, long service life can be applied on the express elevator.

For strengthening resistance to tension of the present utility model, the optional position left-right symmetric is provided with two steel cables in the oversheath; Also can in oversheath, a steel cable be set symmetrical center.The setting of steel cable, it is more reliable that the utility model is used.

For guaranteeing stranded rounding property, the described bunch of cables of two control cores that contains is by two control cores and two stranded forming of gasket for packing; The center that is twisted into bundle at four every group control cores also can be provided with gasket for packing.

Embodiment

As figure, be Flat PVC insulated lift cable, comprise that section is pancake oversheath 5, be provided with 20 six roots of sensation control core 1 in the oversheath 5, a ground connection core 3 and two pair twist shielded signal wire 4, wherein 24 control cores are divided into two groups, control cores by 12 for every group and be divided into three beams, be distributed in the side in the oversheath 5 behind the stranded bunchy of every Shu Yousi root control core 1-1 side by side, two groups of both sides control cores are symmetrically distributed in the oversheath 5, remains two control core 1-2 and are twisted into bunch of cables and ground connection core 3 and two pair twist shielded signal wire 4 and are set up in parallel at above-mentioned two groups and control between the cores.The optional position left-right symmetric is provided with two steel cables 6 in the oversheath 5, also can be provided with a steel cable in symmetrical center in oversheath 5, and its purpose is to strengthen the tensile strength of cable; The bunch of cables that two control of above-mentioned residue core is twisted into is by two control core 1-2 and two stranded forming of gasket for packing 2-2, and the center of the stranded bunchy of every Shu Sigen control core 1-1 is provided with gasket for packing 2-1.The insulating barrier of the insulating barrier of described control core 1, ground connection core 3 and oversheath 5 are made by pvc material; The insulating barrier of pair twist shielded signal wire 4 is made by vinyl chloride.

The utility model energy reliability application is at the High-speed Electric that can hang length 150m and translational speed 10m/s On the ladder, have that tensile strength is big, the advantage of bend-resistance, long service life.
