Abstract

A grab bucket cable for a ship relates to the field of cables and comprises a cable core, a butyronitrile PVC composite elastomer inner protection layer, a polyester fiber yarn general weaving tensile layer and a flame-retardant polyurethane elastomer outer protection layer which are sequentially arranged from inside to outside; the cable core includes that one strengthens sinle silk, many power sinle silks and many dacron multifilament rope and fills the reinforcement, and many power sinle silks equipartition are in the periphery of strengthening the sinle silk, and every power sinle silk all includes the stranded tinned copper wire stranded conductor of outer high strength ethylene propylene rubber insulating layer and inlayer. The utility model discloses adopt the concentric type to constitute jointly by four power sinle silks, the conductor guarantees normal power supply, strengthens sinle silk and dacron multifilament rope and fills the circularity that the reinforcement had both improved strength and kept the cable core, and interior sheath, weaving tensile layer and outer jacket protection cable core. The utility model can endure long-time winding movement, and has excellent tensile, pressure-proof, bending, wear-resistant, oil stain property and the like.

Description

Grab bucket cable for ship

Technical Field

The utility model relates to a field of cable especially relates to the structure of the marine cable of grab bucket.

Background

In recent years, with the development of silt coast port construction, silt problems of silt coast, especially channel siltation problems, are more and more prominent, in order to clean up silt of a channel in time and ensure smooth passing of ships, various grab ships for wharf tunnel engineering are actively injected for use, a common rubber sleeve cable originally matched with a grab ship lifting tool device is difficult to adapt to long-time operation requirements, core breaking and cracking are often caused, the lifting tool cannot work normally due to power failure, the production efficiency is reduced, the service life is extremely short, frequent replacement is realized, the cost is high, waste is large, potential safety hazards are caused, and in view of the situations, a special power cable meeting the requirements of grab ship field operation is researched and developed from the aspects of cable design, process and materials, and the special power cable is an important task for cable scientific research and production enterprises.

Disclosure of Invention

The utility model aims at overcoming the not enough of prior art, provide a long service life's marine grab bucket cable.

The purpose of the utility model is realized like this: the grab bucket cable for the ship comprises a cable core, a butyronitrile PVC composite elastomer inner protection layer, a polyester fiber yarn general weaving tensile layer and a flame-retardant polyurethane elastomer outer protection layer which are sequentially arranged from inside to outside; the cable core includes that one strengthens sinle silk, many power sinle silks and many dacron multifilament rope and fills the reinforcement, and many power sinle silks equipartition are in the periphery of strengthening the sinle silk, and every power sinle silk all includes the stranded tinned copper wire stranded conductor of outer high strength ethylene propylene rubber insulating layer and inlayer.

The utility model discloses a strengthen the sinle silk and include the galvanized wire rope of outer rubber insulation layer and inlayer, increase strength.

The utility model discloses a power sinle silk has four, dacron multifilament rope packing reinforcement has four.

The utility model discloses adopt the concentric type to constitute jointly by four power sinle silks, interior sheath and outer jacket all adopt extrusion formula technology, utilize the technique gimmick that the compound hank direction of conductor and sinle silk stranding direction are unanimous. The conductor guarantees normal power supply, strengthens the sinle silk and dacron multifilament rope and fills the reinforcement and both improved strength and keep the circularity of cable core, and interior sheath, weaving tensile layer and outer jacket protection cable core. Make the utility model discloses can stand long-time coiling motion, extremely excellent tensile, withstand voltage, crooked, wear-resisting, greasy dirt characteristic etc. are applicable to and exchange under the 50HZ, and rated voltage is at the marine grab bucket device power interconnecting link of 1KV and below.

The utility model discloses rational in infrastructure simple, it is easy to manufacture, compact structure, preparation simple process, and it is extremely convenient to install and maintain.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in fig. 1, the grab bucket cable for the ship comprises a cable core, a butyronitrile PVC composite elastomer inner protection layer 5, a polyester fiber yarn general weaving tensile layer 6 and a flame retardant polyurethane elastomer (TPU) outer protection layer 7 which are sequentially arranged from inside to outside. The cable core is by a enhancement sinle silk 3, four power sinle silks 8 and four dacron compound silk rope fill reinforcers 4 and constitute, and four power sinle silks 8 equipartitions are in the periphery of strengthening sinle silk 3, strengthen sinle silk 3 and include outer rubber insulation layer 10 and the zinc-plated wire rope 9 of inlayer, and rubber insulation layer 10 parcel is on zinc-plated wire rope 9. Each power wire core 8 comprises an outer ethylene propylene rubber insulation layer 2 and an inner multi-strand tinned copper wire stranded conductor 1, and the high-strength ethylene propylene rubber insulation layer 2 is wrapped on the multi-strand tinned copper wire stranded conductor 1. Each polyester multifilament rope filling reinforcing piece 4 is respectively arranged between two adjacent power wire cores 8.

The utility model discloses have extremely excellent tensile, wear-resisting, crooked, withstand voltage characteristic, can stand long-time receipts, put the motion, the operating temperature that the cable conductor allows for a long time is up to 90 ℃, the removal friction temperature is allowed to be up to 120 ℃ under the cable operating condition, the ambient temperature of use is not less than-45 ℃, the installation lays the temperature and is not less than-25 ℃.
