Abstract
The utility model relates to an explosion-proof trailing cable applied to an elevator. The cable comprises at least three conductor groups which are parallelly arranged side by side in a row. Each conductor group comprises six copper clad steel stranded conductors with insulations. Six conductors are arranged in a circle, and an elastic filling rope is arranged in a gap defined by six conductors. Six conductors are coated with a tin drainage line and a shielding layer in order. All conductor groups are coated with a sheath. Each copper clad steel stranded conductor is formed by stranding a number of fine copper clad steel wires with the diameter of 0.1mm to 0.2mm, wherein the copper content is 40%. The insulation is elastomer PVC insulation. Each shielding layer is formed by wrapping an aluminum-plastic compound tape. The sheath is a TPU elastomer sheath. The cable provided by the utility model has the advantages of excellent shielding performance and anti-jamming performance.
Description
Technical field
The utility model relates to a kind of explosion-proof trailing cable, specifically the explosion-proof trailing cable of elevator.
Background technology
The trailing cable that elevator is used is according to IEC 60227.6 and GB 5023.6 standard production, is applicable to rated voltage 300/500V(or 450/750V) and the circumnutating property connection flat cables such as following elevator and elevation and subsidence mechanical equipment, power supply power connecting line be used as.Conductor adopts filament diameter to be not more than the 5th kind of stranded conductor of 0.21mmTR type copper wire, the long-term working temperature that allows is no more than 70 ℃, lay ambient temperature and should be not less than 0 ℃, free suspension length is installed and is no more than 35m, translational speed is no more than 1.6m/ second, and cable laying installation permission bending radius should be not less than 6 times of the little limit of cable.At present the steel wire rope of such cable occurs the risk detached, and the soft copper conductor is prone to the phenomenon of disconnected core in running, affects the work of elevator inner part.
There are elevator and the elevation and subsidence mechanical equipment of the occasion use of explosion hazard in chemical industry, petrochemical industry, gas engineering, mine etc., for the generation of avoiding blast all requires to adopt explosion-proof lift.The same trailing cable used on elevator also should possess the explosion-proof performance of essential safety, and general trailing cable in use easily produces the gathering of static, does not possess explosion prevention function.
Summary of the invention
The utility model is intended to overcome the defect of prior art, provides a kind of elevator explosion-proof trailing cable, has excellent shielding properties and interference free performance.
In order to solve the problems of the technologies described above, the utility model is achieved in that
The explosion-proof trailing cable of a kind of elevator, it comprises at least three conductor groups, they are parallel is arranged in a row side by side, it is characterized in that: each conductor group comprises the copper covered steel stranded conductor of six tape insulations, the arrangement that forms a circle of six conductors, be provided with the elasticity gasket for packing in the middle of it, the outside of six conductors is surrounded by zinc-plated drainage thread and screen successively, and the outside of all conductor groups is surrounded by a sheath.
The explosion-proof trailing cable of described elevator is characterized in that: described copper covered steel stranded conductor is that multiply 0.1mm-0.2mm copper content is that 40% thin welding wire is stranded forms.
The explosion-proof trailing cable of described elevator is characterized in that: described insulation is elastomer PVC insulation.
The explosion-proof trailing cable of described elevator is characterized in that: to be that aluminium-plastic tape is wrapped form described screen.
The explosion-proof trailing cable of described elevator is characterized in that: described sheath is the TPU elastic body jacket.
The beneficial effects of the utility model are: optimized the structure of existing use with the trailing cable of steel wire load-bearing, improved the tensile strength of conductor, improved cable reliable rows in use, the characteristic that has possessed essential safety, can meet the explosion-proof lift requirement of using in there are the explosion hazard occasion in chemical industry, petrochemical industry, gas engineering, mine etc. fully.
The accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1: the explosion-proof trailing cable of a kind of elevator, it comprises eight conductor groups, they are parallel is arranged in a row side by side, each conductor group comprises the copper covered steel stranded conductor 1 of six tape insulations 2, the arrangement that forms a circle of six conductors, the outside that is provided with 3, six conductors of elasticity gasket for packing in the middle of it is surrounded by zinc-plated drainage thread 5 and screen 4 successively, and the outside of all conductor groups is surrounded by a sheath 6; Described copper covered steel stranded conductor 1 is that 40% thin welding wire is stranded forms for multiply 0.1mm-0.2mm copper content, this copper covered steel stranded conductor intensity reaches 780 MPa, be far longer than the tensile strength of copper wire 230 MPa, improved the intensity of cable conductor, prevent the appearance of disconnected core phenomenon, improved cable reliable rows in use.Contemporary for the steel wire load bearing element in trailing cable.Because the steel in the copper covered steel stranded conductor has conduction and drawing-resistant function concurrently, with existing use, with the trailing cable of steel wire load-bearing, compare, can save the use amount of copper material, alleviate the weight of cable; Described insulation 2, for elastomer PVC insulation, is played electric insulation and anti-flecition; Described screen 4 forms for aluminium-plastic tape is wrapped, an included tin-coated copper drainage thread 5, make so whole cable in idiostatic, can not produce electrostatic charge, whole cable is low electric capacity, the difficult electric charge of storing, good shielding properties and antistatic property are arranged, even circuit is short-circuited or electric spark, the flammable explosive gas around also being not enough to light; Described sheath 6 is the TPU elastic body jacket, adopts the extrusion way of squash type, will become cable core space padding and compacting, has guaranteed the stability of cable.
Claims (5)
