Abstract
The utility model discloses a high tension-resisting flexible cable for a crane control button and a power supply system. The cable consists of a conductor, an insulating layer, a filling layer, a belting layer and a jacket layer from inside to outside; the outer circle of the jacket layer is divided into three equal sections respectively provided with tension-resisting steel wire ropes; outer jackets are respectively arranged outside the tension-resisting steel wire ropes; and the outer jackets and the jacket layer of the cable form an integrated structure. The cable can uniformly bear a tension force, and the whole cable cannot be easily deformed; the steel wire ropes have the advantages that the steel wire ropes have strong tension-resisting capability and cannot be easily bent and deformed; therefore, the insulating jacket layer and the conductor cannot be cracked and deformed, can run safely and can be broadly applied to operating buttons to crane control systems or the power supply systems of various gantry, bridge, girder and floor rail type cranes.
Description
Technical field:
The utility model relates to a kind of tension flexible cable, especially a kind of crane control button and power-supply system high tensile flexible cable.
Background technology:
In the special industries such as driving and crane, cable provides power and signal controlling operation for equipment, this type of cable performance requires high, structure is comparatively complicated, and its cross section generally can be circle or flat, at present, there is following defective in the employed control cable of this kind equipment: because cable in use not only will bear the gravity of self, but also to bear the pulling force that moves back and forth and produced from equipment, and therefore cause the core of cable to fracture easily, cause and scrap; Also have, cable in use needs frequently to move, and produces slippage between the core of cable and the sheath, and insulated wire cores is stretched out outside the sheath, and insulation is stretched, and when heavy current was passed through, cable was breakdown easily.And this present class cable is soft inadequately, and flexibility is little, and stretching resistance is little, and conductor ruptures easily, in use if cable breaks down and often causes the generation of production accident.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of crane control button and power-supply system high tensile flexible cable, this cable has higher pliability, and stronger tensile property bends repeatedly that conductor does not rupture, insulation and sheath chap line not.
The utility model technical solution problem adopts following technical scheme:
A kind of crane control button and power-supply system high tensile flexible cable, the cable from-inner-to-outer is made up of conductor, insulating barrier, packed layer, belting layer, restrictive coating, it is characterized in that, described restrictive coating excircle three equal parts are provided with the tension hawser, the periphery of tension hawser is provided with oversheath, and the restrictive coating of oversheath and cable itself forms integrative-structure.
Described conductor adopts the stranded conductor wire core of the special soft copper of the 6th class.
Described restrictive coating adopts the high flexibility elastomeric material.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Cable conductor is compact pliable and tough, easy fracture not, and promptly this cable has higher pliability, is flexible about 10 times of general cable; Insulating barrier and restrictive coating have excellent weather resisteant, heat-resistant aging and excellent tensile strength and toughness, resilience and excellent compression set and good electrical insulation properties, simultaneously insulation, restrictive coating chap line not also; Three soft hawsers (single diameter is between 1.0 ~ 4.0mm) have been added at equal equal portions on the cable jacket, make it have tension and stressed uniform characteristic, its tensile strength can reach 1500Mpa, thus guarantee restrictive coating and conductor do not rupture, indeformable, and operation safely.The utility model cable softness, tension, the control cable and the electric power system cable that have solved running control system are soft inadequately, flexibility is little, stretching resistance is little, conductor is the problem of fracture easily, makes its action button that is widely used in various gantry, bridge-type, beam type, floor rail type driving to running control system and power-supply system.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Number in the figure: 1 conductor, 2 insulating barriers, 3 packed layers, 4 belting layers, 5 restrictive coatings, 6 tension hawsers, 61 oversheaths.
Embodiment:
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.Embodiment, non-limiting examples is as described below:
Embodiment: shown in Figure 1, conductor 1 adopts the soft tinned copper wire of multiply of the 5th class formation to be twisted into conductor wire core, and conductor production is through a following youngster step: wire drawing-annealing is zinc-plated-and synnema-(multiple strand), conductor adopts restraints the form of twisting, and the cross section is at 6mm
2Following conductor adopts the synnema form, and the cross section is at 6mm
2And above conductor, because the cross section is big, conductor monofilament radical is too many, also will carry out multiple strand, wherein 2.5mm behind synnema
2With monofilament maximum gauge in the lower conductor is 0.16mm, 4-35mm
2The monofilament maximum gauge is 0.21mm in the conductor, 50-150mm
2The monofilament maximum gauge is 0.31mm in the conductor, 185mm
2With monofilament maximum gauge in the upper conductor is 0.41mm.Insulating barrier 2 adopts the high flexibility elastomeric material, adopts plsitive mold to extrude, and temperature is controlled between 160 ± 10 ℃; Packed layer 3 adopts the rope made of hemp to fill, and keeps the rounding property of cable shape; Belting layer 4 is that nonwoven fabrics is wrapped, and employing is put up wrapped, puts up rate 20%; Tension hawser 6 adopts three, and carefully (single diameter is embedded in restrictive coating 5 and is the three equal parts setting at 1.0 ~ 4.0mm) soft tension hawsers; The periphery of tension hawser 6 is provided with oversheath 61, and oversheath 61 forms integrative-structure with the restrictive coating 5 of cable itself.High flexibility elastomeric material restrictive coating 5 equally also adopts plsitive mold to extrude, and temperature is controlled between 150～170 ℃, can adjust mould according to the actual conditions of equipment and material.
