Abstract
The utility model relates to a cable used in hoisting equipment and especially relates to a rubber roll cable used in the hoisting equipment. The reinforced rubber roll cable used in the hoisting equipment comprises main core conductors with ethylene propylene diene monomer insulation, earth wire core conductors with the ethylene propylene diene monomer insulation, a chlorinated polyethylene rubber inner sheath and a chloroprene rubber or a chlorinated polyethylene rubber outer sheath. A polyester filament braiding layer is arranged between the inner sheath and the outer sheath. A reinforcement component used to support the main core conductors and the earth wire core conductors is also comprised. A cross section of the reinforcement component is similar to a triangle. Three vertexes and three edges are in an inner concave arc shape. The main core conductors are arranged on arc portions of the triangle edges respectively and the earth wire core conductors are arranged on the arc portions of the triangle vertexes respectively. By using the cable of the utility model, flexibility, bending resistance performance and torsional resistance performance of the cable conductor are increased.
Description
Technical field
The utility model relates to the hoisting equipment cable, relates in particular to hoisting equipment rubber drum cable.
Background technology
At present hoisting equipment is with drum cable ubiquity cable low problem in useful life, and after cable came into operation, under bending repeatedly, fracture appearred in conductor, causes cable termination in useful life and needs to change cable, and the cable user use cost is high.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and a kind of hoisting equipment enhanced rubber drum cable is provided.The flexibility of the utility model raising cable conductor and resistance to bend(ing), the anti-performance of turning round.
For addressing the above problem, a kind of hoisting equipment enhanced rubber drum cable, it comprises master core conductor and ground wire core conductor, chlorinated polyethylene rubber inner sheath and neoprene or the haloflex rubber oversheath that respectively carries the ethylene propylene diene rubber insulation, is provided with the dacron thread braid between described inner sheath and the oversheath; It also comprises the reinforcement that supports master core conductor and ground wire core conductor, the cross section of this reinforcement is subtriangular, its three summits and three arcs that the limit all is indent, described master core conductor is located at respectively the arc place of described triangle edges, and the ground wire core conductor is located at respectively the arc place on described triangle top.
Described hoisting equipment enhanced rubber drum cable, wrapped one deck polyester belt forward all on described master core conductor and the ground wire core conductor.
The utility model adopt to be strengthened structure as middle reinforcing element, and conductor also use polyester belt, and adopt forward lay configuration, with the flexibility of raising cable conductor and anti-bending, the anti-performance of turning round.Cable has good flexibility, and bending resistance, cold resistance, weatherability, ozone resistance, UV resistant performance excellence are than the long service life of the similar cable of tradition.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model schematic diagram.
Embodiment
As shown in Figure 1, a kind of hoisting equipment enhanced rubber drum cable, it comprises master core conductor 2 and ground wire core conductor 3, chlorinated polyethylene rubber inner sheath 4 and neoprene or the haloflex rubber oversheath 5 that respectively carries ethylene propylene diene rubber insulation 1, is provided with dacron thread braid 6 between described inner sheath and the oversheath; It also comprises the reinforcement 7 that supports master core conductor and ground wire core conductor, the cross section of this reinforcement 7 is subtriangular, its three summits and three arcs that the limit all is indent, described master core conductor is located at respectively the arc place of described triangle edges, and the ground wire core conductor is located at respectively the arc place on described triangle top.
Described hoisting equipment enhanced rubber drum cable, wrapped one deck polyester belt (not shown) forward all on described master core conductor and the ground wire core conductor.
After copper wire drawing is complete, carry out conductor resistance rate test and test of elongation rate, after the test passes, change the synnema operation over to, in copper wire, incorporate into during synnema and spin the synthetic fibre silk, detect qualified after, enter multiple strand operation, the outermost layer conductor twists to being left-hand.After conductor is stranded, need carry out conductor diameter, the outermost layer pitch is measured, the conductor DC resistance test after the test passes, changes over to and squeezes the insulation operation, super soft ethylene propylene diene rubber is adopted in insulation, detect the average thickness of insulation, the thinnest point, thickest point calculates corresponding concentricity, carries out simultaneously insulate heat and extends, concentricity, after the heat extension is qualified, change the stranding operation over to, during stranding, the saddle-shape reinforcing element is placed cable center, three-phase power core places in the groove, the ground core places the edge, after the stranding detection is qualified, enters inner sheath and extrudes operation, inner sheath adopts soft chlorinated polyethylene rubber, inner sheath extrude complete after, need carry out hot elongation test, after the pass the test, enter the reinforcing braid operation, adopt dacron thread evenly to be woven in outside the inner sheath, weave complete after, enter oversheath and extrude operation, oversheath adopts soft chlorinated polyethylene rubber, after cable went out bosh, the thinnest point was carried out in sampling, thickest point, average thickness is measured, the measurement of the projects such as heat extension.Measure qualified after, continue start, produce complete after, change the finished product operation over to, carry out manufacture test, after the pass the test, add a cover the quality certificate, dispatch from the factory.
