Description
Technical field
The present invention relates to electric cable for coal mining machine fields, are specifically related to a kind of intelligent flame retarding flat coalcutter Plastic-sheathed Cable.
Background technique
Coal is one of China's important energy source, is increasingly increased as economic construction of China continues to develop power requirement, coal
Charcoal dosage is also increasing, is faced with exhausted danger.Major coal mine steps up the exploitation to girdle, and conventional electric cable for coal mining machine is not
It is able to satisfy the needs of low seam mining machinery.
Since coalcutter is to move back and forth during coal mining, coalcutter and electrical power control cabinet are far, need with very long
Cable connects.And the severe bends of the figure of eight or serpentine can even occur for cable in moving process.Curved cable
Inner ring core is subject to large compressive and the outer ring core of cable by very big pulling force, in coalcutter walking to cable shape again
At very big longitudinal pulling force.General electric cable for coal mining machine be it is round, since bending radius is small when using on thin seam working surface
Conductor easy fracture, cable can play fire-retardant no toxic gas release, have Anti-Jamming, since bog-head coal sheaf space is narrow when meeting fire
Small, people is difficult execute-in-place.This requires that one side coalcutter system should have the protection function to cable bend and burning
Can, anti-interference and function for monitoring.For coalcutter under conditions of underground is this severe, this is clearly to be difficult to accomplish, on the other hand
Cable itself, which must be taken into consideration, should have certain flexibility and bending resistance, and in burning, micro- cigarette is discharged without toxic gas, resist
Interference and information transfer capability.That is cable bend certain radius at a certain temperature, continuous thousands of times or even up to ten thousand times, cable
Normal operation can still be maintained, cable conductor does not break, and insulation and sheath material also do not crack, micro- in burning
Cigarette is discharged without toxic gas, strong antijamming capability and information transfer capability.There are no one kind to have intelligent, bending resistance so far
The low seam mining machinery private cable of the characteristics such as song, low smoke and zero halogen, fire-retardant.
Summary of the invention
1. technical problems to be solved
The technical problem to be solved in the present invention is that providing a kind of intelligent flame retarding flat coalcutter Plastic-sheathed Cable, have
The characteristics such as intelligence, resist bending, low smoke and zero halogen, fire-retardant can be applied to the power supply of the various coalcutters of girdle and similar devices
Connection, cable can be moved freely with coalcutter and similar devices, improve the use scope and service life of cable.
2. technical solution
To solve the above problems, the present invention adopts the following technical scheme that:
A kind of intelligence flame retarding flat coalcutter Plastic-sheathed Cable, including oversheath and the control line being wrapped in inside oversheath
Core and power wire core, the power wire core are successively arranged power core conductor, power core conductor shielded layer, power from the inside to the outside
Core insulating layer, power wire core insulation screen and power wire core metal screen layer, the power wire core metal screen layer double as
Ground wire；The control conductor is successively arranged control core conductor, control core insulation layer and control conductor metal screen from the inside to the outside
Cover layer；
The oversheath is in flat, and the power wire core and control conductor arrange in a row, in the control core conductor
Equipped with tension silk, radio frequency core and optical transmission unit, the radio frequency core are additionally provided on the inside of the control conductor metal screen layer
It is successively arranged radio frequency cable core conductor, radio frequency line core insulation layer, radio frequency conductor screen and radio frequency core restrictive coating from the inside to the outside；Institute
The nonmetallic loose tube structure that optical transmission unit is center of circle central tubular is stated, the optical transmission unit is placed in control conductor metallic shield
The center point of layer, the radio frequency core and the control core conductor for being coated with control core insulation layer are surrounded on optical transmission unit week
Side, the control conductor metal screen layer are coated with cable core sheath；The power wire core insulating layer, control core insulation layer and
The material of radio frequency line core insulation layer is same using ethylene-propylene diene copolymer as the low smoke and zero halogen rubber of base-material, the material of the oversheath
Matter is different from each insulating layer using ethylene-propylene diene copolymer as the low smoke and zero halogen rubber of base-material.
Further, the power core conductor, control core conductor and radio frequency cable core conductor are all made of tin plating soft copper and lead
Body.
Further, the control core conductor, which is used, makees tension silk with high intensity spinning synthetic fibre silk fiber, with tin plating soft copper
Method of the line layered windings on spinning synthetic fibre silk fiber is made.Its pitch very little, its length is raw footage after the expansion of conductor monofilament
1.5 times or more, when being bent and being dilatory, like a spring, most active force all concentrates on spinning synthetic fibre silk fibre conductor cable
It ties up on material, breaks to efficiently avoid control core conductor and be pulled off with curved.
Further, the power core conductor and radio frequency cable core conductor are all made of the thin tin-coated copper strands of multiply and twist and answer
The method of strand is made, and stock strand is identical with the direction twisted again.So that the flexibility and ductility of cable are preferable, cable in bending and
When dilatory, conductor stress very little, effectively avoids power core conductor and radio frequency cable core conductor is pulled off and breaks with curved.
Further, the power wire core metal screen layer is woven by tin annealed copper wire, the power wire core metal
It is surrounded with nylon belting layer outside shielded layer, is equipped on the inside of the control conductor metal screen layer and is wrapped in radio frequency core and is coated with
Cable core nylon belting layer outside the control core conductor of control core insulation layer.Power wire core surface layer is to be woven by tin annealed copper wire
Made of power wire core metal screen layer, can be effectively controlled power wire core to extraneous interference, and be equipped on the outside of control conductor
Control conductor metal screen layer can be effectively controlled extraneous interference, so as to efficiently coalcutter be avoided to malfunction.Because nylon
Skin-friction coefficient is small, can reduce between power wire core and oversheath, radio frequency core and the control for being coated with control core insulation layer
Friction between cable core conductor processed and control conductor metal screen layer, so that can produce between the component of nylon belting layer two sides
Slight sliding, and then can prevent the core for putting place when cable Long-term bend by bending from fatigue fracture occurs.
Further, the optical transmission unit is coated with chain armor.Chain armor by optical transmission unit with
While radio frequency core and control core conductor separate, protective action can be played to optical transmission unit, and enhance optical transport list
The mechanical performance of member.
