Description

Flexible towline cable

Technical Field

The utility model relates to the technical field of cables, especially, relate to a flexible towline cable.

Background

The towline cable is a high-flexibility special cable which can move back and forth along with the towline and is not easy to wear, and is called the towline cable, and is generally called the towline cable and the tank chain cable.

The existing drag chain cable is mostly of a multi-strand structure or a single-core structure, the drag chain cable of the single-core structure usually lays a plurality of cables at one time, and sometimes dozens of cables are laid, so that the mode is not only unfavorable for the installation of the cables, the cables are twisted with each other after being used for a long time, the friction force between the cables is large, the stress between the cables is uneven, and the cables are easily broken.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a flexible towline cable in order to remedy prior art's defect.

The utility model discloses a realize through following technical scheme:

the utility model provides a flexible towline cable, including the support chassis, the support chassis including four orthodrome skeletons that are four corners setting, and four orthodrome skeletons' outer wall is tangent, be equipped with the little pipe in center in the central space that four orthodrome skeletons constitute, there is the big pipe in outer lane in the outside cover of four orthodrome skeletons, be equipped with little orthodrome between per two adjacent orthodrome skeletons respectively, be equipped with sinle silk one respectively inside every orthodrome skeleton, be equipped with sinle silk two respectively inside every orthodrome skeleton, the outside cladding in the big pipe of outer lane has galvanized steel wire to weave the shielding layer in proper order, no seam lead alloy inner sheath and two steel band armor polyvinyl chloride oversheath.

The first wire core comprises a first conductor, a microporous polytetrafluoroethylene insulating layer, a ceramic fiber heat-insulating woven layer and an aluminum tape interlocking armor layer, wherein the microporous polytetrafluoroethylene insulating layer, the ceramic fiber heat-insulating woven layer and the aluminum tape interlocking armor layer are sequentially coated on the outer side of the first conductor.

And the second wire core comprises a second conductor, an ethylene propylene diene monomer insulating layer, a tinned soft copper wire and a polyester wire braided insulating shielding layer, wherein the ethylene propylene diene monomer insulating layer and the tinned soft copper wire and polyester wire braided insulating shielding layer are sequentially coated on the outer side of the second conductor.

And a gap between the central small circular tube and the outer ring large circular tube is filled with a water-blocking aramid yarn filling layer.

The utility model has the advantages that: the utility model discloses be equipped with four tangent big circular arc skeletons and four small circle arc skeletons in proper order between the big pipe in center pipe and outer lane, sound construction, antitorque can be good, puts the sinle silk in the circular arc skeleton, and when the cable distortion, the circular arc skeleton can alleviate the twisting power of sinle silk, and fine protection sinle silk does not receive the damage, still is difficult for the rupture, longe-lived.

Detailed Description

As shown in fig. 1 and 2, a flexible drag chain cable, including supporting framework, supporting framework including be four orthodrome skeletons 1 that are four corners setting, and the outer wall of four orthodrome skeletons 1 is tangent, be equipped with central little pipe 2 in the central space that four orthodrome skeletons 1 constitute, the cover has outer lane orthodrome 3 in the outside of four orthodrome skeletons 1, be equipped with little circular arc skeleton 4 between per two adjacent orthodrome skeletons 1 respectively, be equipped with sinle silk one inside every orthodrome skeleton 1 respectively, be equipped with sinle silk two inside every small circle arc skeleton 4 respectively, the cladding has galvanized steel wire to weave shielding layer 5, no seam lead alloy inner sheath 6 and two steel band armor polyvinyl chloride oversheath 7 in proper order in the outside of outer lane orthodrome 3.

The first wire core comprises a first conductor 8, a microporous polytetrafluoroethylene insulating layer 9, a ceramic fiber heat-insulating woven layer 10 and an aluminum tape interlocking armor layer 11, wherein the microporous polytetrafluoroethylene insulating layer 9, the ceramic fiber heat-insulating woven layer 10 and the aluminum tape interlocking armor layer are sequentially coated on the outer side of the first conductor 8.

And the second wire core comprises a second conductor 12, an ethylene propylene diene monomer insulating layer 13 and a tinned soft copper wire and polyester wire braided insulating shielding layer 14, wherein the ethylene propylene diene monomer insulating layer 13 and the tinned soft copper wire and polyester wire braided insulating shielding layer are sequentially coated on the outer side of the second conductor 12.

And a gap between the central small round pipe 2 and the outer ring large round pipe 3 is filled with a water-blocking aramid yarn filling layer 15.

The seamless lead alloy inner sheath 6 can be used as a waterproof protective layer to ensure that the conductor of the cable core is prevented from being invaded by moisture and water.
