Description

Low-pressure high-strength degree tension flexibility reel cable

Technical field

The utility model relates to a kind of cables, and in particular to a kind of low-pressure high-strength degree tension flexibility reel cable.

Background technique

Drum cable is applied to rotary machine, Transport Machinery and conveyer, and drum cable can also be used in drag chain system simultaneously Make reel and trailing cable.Drum cable carries out movement of taking down the exhibits with dragging the guiding of axis or other similar devices.Such cable makes Often require that bending radius is smaller in.Drum cable bending radius depends on the construction of cable and outer diameter, cable itself and its peace Dress and usage mode.Drum cable structure by being generally conductor, insulation, braiding layer, sheath form.Country's similar product at present, In order to reduce fracture, mostly use increase tensile reinforcement member: such as polyester fiber, cotton is fine, terylene, galvanized mild steel cord etc., but makes It is still very short with the service life.

Utility model content

Utility model aims to solve the above-mentioned prior arts in order to reduce fracture, mostly uses and increases tension reinforcement Part: such as polyester fiber, cotton is fine, terylene, galvanized mild steel cord etc., but service life still very short problem, provides a kind of low Press high-strength tensile flexibility reel cable.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of low-pressure high-strength degree tension flexibility reel With cable, including three master cores, three auxiliary cores and aramid fiber rope, three master cores mutually fit, and aramid fiber is fine Dimension rope is placed in the middle part of three master cores, and the aramid fiber rope is bonded with three master cores, the auxiliary Core is fitted in the outside of adjacent master core respectively, the outside of three master cores, three auxiliary cores and aramid fiber rope Packet is equipped with inner sheath, and the outside packet of the inner sheath is equipped with braiding enhancement layer, and the outside packet of the braiding enhancement layer is equipped with outer shield Set, the master core and auxiliary core include conductor, conductor belting layer and insulating layer, and the outside packet of the main conductor is set There is conductor belting layer, the outside packet of conductor belting layer is equipped with insulating layer.

Preferably, if the conductor is to be twisted carried interest circle annealing copper wire or tinned wird using fine pith processing method The circular cross section minimum bending radius of synthesis is the 5th kind of flexible conductor of 6 times of outside diameters of cable.

Preferably, the insulating layer is ethylene propylene rubber insulated layer.

Preferably, the braiding layer is fiber braiding layer.

The substantial effect of the utility model is: primary structure is by conductor, insulating layer, stranding wrapping layer, sheath, volume Knit enhancement layer, external sheath layer composition.Cable conductor is twisted using multiply circle annealing copper wire or tinned wird (the 5th kind of flexible conductor) At circle, insulation uses ethylene propylene rubber insulated, wrapped band after stranding, after extrude one layer of sheath, reinforcement is woven outside sheath Layer, finally extrudes external sheath layer.The innovative point of this product is that cable center adds an aramid fiber rope, sheath+braiding layer+ Outer jacket, three-decker are closely sticked together, and increase the tensile strength of cable, to effectively raise making for cable Use the service life.Conductor uses the tin plating soft copper silk of 5 classes, and stranding cable core adds aramid fiber rope one by one (intensity be wirerope 5 ~ 6 times), And insulation, sheath use rubber, and cable is made to have more excellent flexibility.Add one layer of braiding enhancement layer between inner sheath and oversheath Structure.Make cable that there is time buffer function when being stretched or being bent, and material (sheath material, braiding) has in itself It is high-intensitive.Above 3 kinds of processing technologys improve the service life of the cable.

Detailed description of the invention

Fig. 1 is the overall structure diagram of the utility model.

In figure: 1, conductor, 2, conductor belting layer, 3, insulating layer, 4, inner sheath, 5, braiding enhancement layer, 6, oversheath, 7, Aramid fiber rope.

Specific embodiment

Below by specific embodiment, and in conjunction with attached drawing, the technical solution of the utility model is made further specifically It is bright.

Embodiment 1:

A kind of low-pressure high-strength degree tension flexibility reel cable, it is characterised in that: including three master cores, three auxiliary lines Core and aramid fiber rope 7, three master cores mutually fit, and aramid fiber rope is placed in the middle part of three master cores, The aramid fiber rope is bonded with three master cores, and the auxiliary core is fitted in the outside of adjacent master core respectively, The outside packet of three master cores, three auxiliary cores and aramid fiber rope is equipped with inner sheath 4, and the outside of the inner sheath is wrapped Equipped with braiding enhancement layer 5, the outside packet of the braiding enhancement layer is equipped with oversheath 6, and the master core and auxiliary core include There are conductor 1, conductor belting layer 2 and insulating layer 3, the outside packet of the main conductor is equipped with conductor belting layer, conductor belting layer Outside packet is equipped with insulating layer.If the conductor is to be twisted carried interest circle annealing copper wire or tinned wird using fine pith processing method The circular cross section minimum bending radius of synthesis is the 5th kind of flexible conductor of 6 times of outside diameters of cable.The insulating layer is that EP rubbers is exhausted Edge layer.The braiding layer is fiber braiding layer.

Primary structure is made of conductor, insulating layer, stranding wrapping layer, sheath, braiding enhancement layer, external sheath layer.Electricity Cable conductor is twisted into circle using multiply circle annealing copper wire or tinned wird (the 5th kind of flexible conductor), and insulation uses EP rubbers Insulation, wrapped band after stranding, after extrude one layer of sheath, weave enhancement layer outside sheath, finally extrude external sheath layer.This production The innovative point of product is that cable center adds an aramid fiber rope, sheath+braiding layer+outer jacket, and three-decker is closely glued It connects together, increases the tensile strength of cable, to effectively raise the service life of cable.Conductor is tin plating using 5 classes Soft copper silk, stranding cable core add aramid fiber rope one by one (intensity be wirerope 5 ~ 6 times), and insulate, sheath uses rubber, make Cable has more excellent flexibility.Add the structure of one layer of braiding enhancement layer between inner sheath and oversheath.Drawing cable There is time buffer function, and material (sheath material, braiding) itself has high intensity when stretching or being bent.Above 3 kinds of processing work Skill improves the service life of the cable.

Embodiment described above is a kind of preferable scheme of the utility model, is not made to the utility model any Formal limitation, there are also other variations and modifications on the premise of not exceeding the technical scheme recorded in the claims.
