Description

Hoist cable

Technical field

The utility model relates to field of cable technology, be specifically related to hoist cable.

Background technology

At present, hoist cable is mainly used in crane, elevator, crimping machine, the occasion of transporter is used as controlling cable, the hoist cable of ordinary construction uses 3+1 structure mostly, there is cable structure uneven, the problem of unbalance stress, and owing to cable own wt is big, at strong pulling force, abrasion, mechanical strength is high, moist, it is dried, in the complex work environment of greasy dirt, it is not by far up to the mark in performance, the hoist cable of this kind of structure there will be distortion in use for some time, fracture, gall line skin, the problem of sheath cracking, to machinery equipment, personnel easily cause serious harm, and electric wire is short for service life.

In order to solve the problems referred to above, design a kind of novel hoist cable particularly necessary.

Summary of the invention

For not enough present on prior art, this utility model purpose is to be to provide a kind of hoist cable, simple in construction, and reasonable in design, it is ensured that the use intensity of cable and resistance to environment, weatherability, ruggedness is strong, and service life is long, safe and reliable, it is easy to promote the use of.

To achieve these goals, this utility model is to realize by the following technical solutions: hoist cable, including outer jacket, anti-twist layer, strengthen load-bearing tensile core, sheath, conductor wire core, Kafra fiber silk, strengthen filled core, wirerope, the external diameter of the wirerope being made up of multiply essence strand finest wire is enclosed with conductor wire core, conductor wire core, strengthen load-bearing tensile core and be enclosed with the reinforcement filled core twisted synthesizing cable of Kafra fiber silk, form cable integral unit, the external diameter of cable integral unit is enclosed with sheath, the periphery of the sheath that outer surface is woven with anti-twist layer is enclosed with outer jacket.

As preferably, described anti-twist layer is uniformly wrapped in the external diameter of sheath, and anti-twist layer uses the braiding of bundles of aramid fiber yarn to form, and can strengthen the tensile strength of whole electric wire.

As preferably, the external diameter of described sheath can be enclosed with the metal knitted sealing coat being made up of proof copper-wire braided, can effectively prevent electromagnetic interference.

As preferably, described outer jacket includes PUR, PVC, TPE, TPV a kind of thermoplastic elastomer (TPE) sheath therein, increases the ruggedness of cable.

The beneficial effects of the utility model: the cable of this kind of structure does not ftractures, pliability is good, self-supporting, tensile strength are high, and heat-resisting, cold-resistant, oil rub resistance, corrosion-resistant, anti-wear performance are well, service life is longer, wide adaptability.

Accompanying drawing explanation

This utility model is described in detail below in conjunction with the accompanying drawings with detailed description of the invention；

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with detailed description of the invention, this utility model is expanded on further.

With reference to Fig. 1, this detailed description of the invention is by the following technical solutions: hoist cable, including outer jacket 1, anti-twist layer 2, strengthen load-bearing tensile core 3, sheath 4, conductor wire core 5, Kafra fiber silk 6, strengthen filled core 7, wirerope 8, the external diameter of the wirerope 8 being made up of multiply essence strand finest wire is enclosed with conductor wire core 5, strengthen filled core 7 is enclosed with Kafra fiber silk 6, conductor wire core 5, strengthen load-bearing tensile core 3, strengthen filled core 7 and be twisted into cable integral unit, the external diameter of cable integral unit is enclosed with sheath 4, the periphery of the sheath 4 that outer surface is woven with anti-twist layer 2 is enclosed with outer jacket 1.

It should be noted that described anti-twist layer 2 is uniformly wrapped in the external diameter of sheath 4, anti-twist layer 2 uses the braiding of bundles of aramid fiber yarn to form.

It should be noted that described outer jacket 1 includes PUR, PVC, TPE, TPV a kind of thermoplastic elastomer (TPE) sheath therein, increase the ruggedness of cable.

Additionally, the material that described enhancing load-bearing tensile core 3 can be had equivalent effect by other forms.

This detailed description of the invention is from inside to outside: add the conductor wire core 5 of the wirerope 8 of multiply essence strand finest wire composition, the reinforcement filled core 7 of parcel Kafra fiber silk 6, strengthen load-bearing tensile core 3, sheath 4, anti-twist layer 2, outer jacket 1, wherein conductor wire core 5 and the reinforcement filled core 7 wrapping up Kafra fiber silk 6, strengthen load-bearing tensile core 3 and twist together stranding, form cable integral unit, strengthen load-bearing tensile core 3 and can strengthen the self-supporting ability of cable itself, cable integral unit wraps up sheath 4 again, electric wire overall mechanical strength can be increased, prevent core at random, increase cable to move, batch the service life of stretching, extension；Anti-twist layer 2 can use bundles of import aramid fiber yarn to weave, can greatly strengthen the tensile strength of whole electric wire, it is effectively improved because cable is frequently batching, the situation of easily torsional deformation under the working condition stretched, also additional proof copper-wire braided composition layer of metal sealing coat can be woven, can effectively prevent electromagnetic interference, it is ensured that the quality of core signal transmission is not affected by extraneous noise；The outer jacket 1 being wrapped in outside anti-twist layer 2 is made up of thermoplastic elastomer material, is greatly enhanced the toughness of electric wire, heat-resisting, cold-resistant, oil rub resistance, corrosion-resistant, anti-wear performance.

This detailed description of the invention uses and adds the wirerope being made up of multiply essence strand finest wire together with conductor sets as power wire core; PUR/TPE/TPV does protective cover material; ensure that use intensity and resistance to environment, the weatherability of cable, travelling performance is good, and tensile strength is high; service life is long; oil resistant is wear-resisting, protects the operation safety of machinery equipment and personnel, good stability; reliability is high, has wide market application foreground.

Of the present utility model ultimate principle and principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, in the range of these changes and improvements both fall within claimed this utility model.This utility model claims scope and is defined by appending claims and equivalent thereof.
