Description
Technical field
The utility model is related to field of cable technology, and in particular to a kind of coal mine moving class flexible cable.
Background technology
Cable is typically by several or several groups of wires are formed around a center is stranded, rope is shaped like, while outside
Layer cover height insulating barrier, mine cable is the abbreviation of coal mine cable, the occasion for needing to move back and forth in unit, in order to
Prevent cable to tangle, wear and tear, pulling, hanging and be at random, often cable is put into cable-pulling chain, cable formation is protected, and electricity
Cable can also be realized with drag chain to be moved back and forth, this drag chain to be followed to be moved back and forth and nonabradable high flexibility Special electric
Cable is just drag chain cable, can generally also be referred to as trailing cable, tank chain cable, the drag chain cable structure of itself is exactly will be common
Cable body be put into drag chain box, it is well known that, due to drag chain cable working condition for long and tortuous or
It is frequently tortuous, if therefore center mode used using common cable body, for cable loss be it is very big, it is electric
Cable is easily broken off, and is caused equipment work to there is failure, has been had a strong impact on production efficiency.
Utility model content
There is composite core, its performance all has limitation.First, original composite core can not produce major diameter, and (diameter is big
In 9.5mm) require；Second, original composite core is easy to crack when reversing；3rd, bending radius is big during original compound chip bending；The
Four, fatigue resistance and antifatigue number of times are relatively low；5th, original easy delamination of composite core external protection.Can not by high-tensile,
These are conflicting for relatively low bending radius, higher windup-degree, higher temperature in use and higher fatigue resistance
Performance requirement effective integration is integrated, and forms high-performance composite materials core.Have limitation in performance, it is impossible to adapt to it is various not
With applied environment and use requirement, applicability is poor.
The patent of example provided above and existing technology also have the shortcomings that common a, composite core for its enhancing cable
Only longitudinal fiber strengthens, and without horizontal or oblique fiber reinforcement, the fatigue resistance of composite core and antifatigue number of times are relatively low,
The service life of cable is affected.And when making cable due to being extruded by aluminium conductor, composite core is easy to crack, and
It can't test out, composite core and the intensity and service life of power transmission cable certainly will be had influence on.
Concrete technical scheme of the present utility model is：A kind of coal mine moving class flexible cable, main body is by composite core, cable
The periphery embedding of core group has intensive sandy soil, and the outer wall of nettle layer is provided with the net in the middle of a circle oversheath, cable core group and oversheath
Several flexible balls are evenly distributed with rope layer, composite core includes inner core, structure sheaf, outer layer, the knot
Structure layer include fiber sleeve and thermosetting resin, the fiber sleeve be by plurality of fibers beam it is interlaced braiding form or along
Inner core axial direction spiral winding is formed, and the outer layer includes the fiber and thermosetting resin arranged along composite core length direction,
The pitch H of the fibre bundle is between 0.1mm-500mm.
Oversheath is made up of tin-coated copper plated aluminium magnesium material.
Nettle layer sets two ends to set ball flexible in jagged breach, and the flexible ball exists
It is uniformly distributed in nettle layer, at least 2, the center of ball is provided with a steel ball.
The beneficial effects of the utility model are：The utility model is novel in design, simple in construction, by entering to common cable
Row is changed, and adds ball, it is ensured that injury-free when cable is in bending, while also enhanced cylinder block strength, secure side
Just, low cost, using effect is obvious.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
A kind of coal mine moving class flexible cable, main body has intensive sandy soil 3 by composite core, the peripheral embedding of cable core group,
The outer wall of nettle layer is provided with the nettle layer in the middle of a circle oversheath 6, cable core group and oversheath and is evenly distributed with several tools
Flexible ball 5, its feature exists, and composite core includes inner core 2, structure sheaf 7, outer layer 1, and the structure sheaf 7 includes fibre
Tie up sleeve pipe and thermosetting resin, the fiber sleeve is to be formed by the interlaced braiding of plurality of fibers beam or along inner core axial direction side
Formed to spiral winding, the outer layer 1 includes the fiber and thermosetting resin arranged along composite core length direction, the fibre bundle
Pitch H between 0.1mm-500mm.
Oversheath 6 is made up of tin-coated copper plated aluminium magnesium material.
Nettle layer sets two ends to set jagged, flexible ball 5 in breach, the flexible ball
It is uniformly distributed in nettle layer, at least 2, the center of ball is provided with a steel ball 8.
