Abstract
The invention discloses a dragging-resistant flexible cable. The dragging-resistant flexible cable comprises three groups of cable cores, wherein tin-plated copper conductors are arranged in the centers of the cable cores; the tin-plated copper conductors are coated with isolation strips, ethylene propylene rubber insulating layers and first flax woven layers in sequence; the three groups of cable cores are arranged in an inner sheath; and the inner sheath is coated with a second flax woven layer and an outer sheath in sequence. Compared with the prior art, the dragging-resistant flexible cable has the advantages that flax is woven at high density outside cable core insulators, flax is woven sparsely outside the inner sheath, and the outer sheath is extruded, so that the outer sheath, a woven structure and the inner sheath are integrated, and the resistance to tension is enhanced greatly.
Description
Technical field
The invention belongs to field of cable technology, be specifically related to a kind of resistance toly drag flexible cable.
Background technology
Sea-freight prosperity makes harbour machinery develop rapidly, but because harbour machinery lifting is frequent, matched cable often needs to do high-speed mobile, bear larger pulling force and bend, usually namely there is various breakage failure about using half a year in traditional flexible cable, impact uses, and needs novel high-performance towing flexible cable supporting with it for this reason.The fillings such as the glass fibre that the many employings of cable are in the past extra or the rope made of hemp, but, no matter adopt which kind of additional materials to fill, between each insulated wire cores in cable core, all easily produce gap, especially for " 3 large 1 little " this common structure flexible cable, all the more so.This just makes the distortion that can produce stranded core in harbour machinery different areas of activity cable loading process, and outer field sheath is because of more soft, and core will protrude and cause cable outward appearance uneven, and physical property and electric property are all subject to very major injury.
Summary of the invention
The object of the present invention is to provide the resistance to of a kind of new construction to drag flexible cable, it is wear-resistant tensile not only, and frequent high-speed mobile pulls also not cracky, thus solves the problem.
For realizing this purpose, technical scheme of the present invention is: one is resistance to drags flexible cable, comprise three groups of cable cores, described cable core center is provided with tinned copper conductor, described zinc-plated soft copper conductor is coated with isolation strip, ethylene propylene rubber insulated layer, the first dimity braid outward successively, be located in an inner sheath in described three groups of cable cores, described inner sheath is coated with the second dimity braid, oversheath outward successively.
As preferably, described oversheath is chloroprene rubber sheath.
As preferably, described zinc-plated soft copper conductor by many tin-coated copper single cords oppositely again strand form.
As preferably, the count of described second dimity braid controls between 60%-75%.
Compared with prior art, the present invention considers that in use procedure, cable need bear larger pulling force, have employed the dimity on the one hand and carry out high density braided outside online core insulation; Also adopt the dimity to carry out open-weave outward at inner sheath on the other hand, and then extrude oversheath, thus oversheath, braiding and inner sheath are combined together, greatly strengthen resistance to tension.Wherein, extrude inner sheath and adopt squash type to extrude high-strength anti-flaming neoprene, so that the position of fixing each insulated wire cores also ensures the gap of tamping between insulated wire cores; Extrude oversheath and then adopt high-strength anti-flaming neoprene, make it infiltrate gap between braid, and be connected into one with inner sheath, improve wear-resistant tensile performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1. zinc-plated soft copper conductor, 2. isolation strip, 3. insulating barrier, 4. the first dimity braid, 5. inner sheath, 6. the first dimity braid, 7. oversheath.
embodiment
The present invention is further described in conjunction with the embodiments with reference to the accompanying drawings.
As shown in Figure 1, one is resistance to drags flexible cable, comprise three groups of cable cores, described cable core center is provided with tinned copper conductor 1, described zinc-plated soft copper conductor 1 is outer is coated with isolation strip 2, ethylene propylene rubber insulated layer 3, first dimity braid 4 successively, be located in inner sheath 5 in described three groups of cable cores, described inner sheath 5 is outer is coated with the second dimity braid 6, oversheath 7 successively.Wherein, described oversheath 7 is chloroprene rubber sheath; Described zinc-plated soft copper conductor 1 is oppositely answered strand by many tin-coated copper single cords and is formed; The count of described second dimity braid 6 controls between 60%-75%.
The present invention is mainly for the resistance to improvement dragging soft cable structure and carry out, the foregoing is only present pre-ferred embodiments, non-ly therefore namely limit to the scope of the claims of the present invention, therefore the simple and easy change of such as doing by specification of the present invention and graphic content and equivalent transformation, all should be contained in the scope of the claims of the present invention.
Claims (4)
