Abstract
The utility model relates to a towline cable with abrasion resistance and winding resistance for harbor machinery. Insulated wire cores are formed by pressing and wrapping insulating layers on the monofilaments of five classes of conductors. Wire group units are formed by a plurality of insulated wire cores. A cable core is formed by filling filling cores comprising high-strength fibre wires between the wire group units. The periphery of the cable core is pressed and wrapt with an inner sheath. The periphery of the inner sheath is woven with a woven shielding layer formed by weaving tinned copper wires. The periphery of the woven shielding layer is pressed and wrapt with an outer sheath. The insulating layers, the inner sheath and the outer sheath of the towline cable with abrasion resistance and winding resistance for the harbor machinery are all made of an elastomeric material. The utility model is a towline cable with abrasion resistance and winding resistance for harbor machinery, which has good abrasion resistance, strong winding resistance, ultraviolet irradiation resistance and long service life and can not generate the phenomena of core breaking and sheath breaking after being repeatedly wound.
Description
Technical field
The utility model relates to a kind of cable, and particularly a kind of wear-resistant, flexibility-resistant drag chain cable for harbor machines belongs to technical field of electric wires and cables.
Background technology
In recent years, the demand cumulative year after year of container hargour hoisting machinery, global harbour machinery output are with the speed increment of annual average near 20%, and the demand of domestic annual harbour machinery manufacturing industry has reached 80 hundred million.World Economics speedup and global trade speedup are the key factors that influences global container volume of trade speedup.The sustainable growth of world's containerized trade amount has stimulated harbour machinery, and particularly the demand of container crane significantly increases, and has directly stimulated the investment that global harbour is newly-built to the container terminal and transform, and the increase of Large Container Ship order.Harbour, the whole world is to the demand of container terminal newly-built investment will increasing container crane, and also will increase upgrading demand of container crane to the transformation of existing harbour.Harbour machinery will improve constantly the requirement of production efficiency, to its attached corollary equipment for example performance requirement such as special cable will be more and more higher also.At present harbour, not anti-circumnutate not wear-resistant with common cable can not adapt to the particularly needs of container crane of harbour machinery far away.The high-performance drag chain cable must be researched and developed and the particularly needs of container crane of harbour machinery could be satisfied.
Summary of the invention
The purpose of this utility model provides that good, anti-the circumnutating property of a kind of resistance to wear is strong, UV resistant according to, can not break after circumnutating wear-resistant, the flexibility-resistant drag chain cable for harbor machines of core, broken skin and long service life repeatedly.
The technical solution of the utility model is: a kind of wear-resistant, flexibility-resistant drag chain cable for harbor machines.The extruded insulation layer is formed insulated wire cores on conductor.Form line group unit by many eradications edge core.Between each line group unit, be filled with core and form cable core.The cable core periphery is extruded with inner sheath.The inner sheath periphery is woven with woven shield.The woven shield periphery is extruded with oversheath.
Described conductor is selected five class conductor monofilament for use, and this monofilament has more stable single wire fracture percentage elongation, and its conductor pitch control evenly.
Described insulating barrier is selected the elastomeric material with high mechanical properties for use.
The described core of filling out selects for use the high strength fibre skein silk to make the high strength fibre rope.
Described inside and outside sheath is all selected elastomeric material for use.
Described woven shield selects for use the tinned copper wire braiding to form, and the braiding coverage density is not less than 80%.
Owing to fill the high strength fibre rope between the online group of unit as filling out core, make this construction of cable consolidation, soft pliable song.Again because insulating barrier and inside and outside sheath are all selected elastomeric material for use.It is low temperature resistant, wear-resistant that this just makes this cable have, the advantage of good bandability and UV resistant.Particularly the sheath material of Shi Yonging can greatly reduce the wearing and tearing between cable and cable, cable and the drag chain, can guarantee that cable is durable in use, the maintenance period of prolonged mechanical equipment.
The utility model has the advantages that provide that good, anti-the circumnutating property of a kind of resistance to wear is strong, UV resistant according to, can not break after circumnutating wear-resistant, the flexibility-resistant drag chain cable for harbor machines of core, broken skin and long service life repeatedly.
