Abstract
The utility model belongs to the field of cables and particularly relates to a stretch-proof cable which comprises a sleeve layer, wherein an elastic layer is arranged in the sleeve layer, a cable core is arranged in the elastic layer, a spring is arranged in the cable core, the cable core consists of a plurality of twisted wire cores, and each wire core is sequentially provided with an insulating layer, a stretch-proof layer and a conductor from the outside to the inside. The utility model has the advantages that the stretch-proof cable improves the tensile strength of the cable and can effectively avoid repeated circumnutating due to frequent moving as well as conductor breaking and insulation cracking due to larger tension so as to guarantee the safety of equipment construction personnel.
Description
Technical field
The utility model belongs to field of cables, especially a kind of stretch-proof cable.
Background technology
Equipment such as driving, derrick crane, straddle truck, lift all carry out operation by motor and automatically controlled its power arm of control.Because these equipment its power arm when work can frequently move, when moving, its power arm drives and motor that the control power arm moves and automatically controlled also will move thereupon and its main power line is had the bigger power of pullling, therefore the motor main power line that is connected power supply with automatically controlled also will be frequently mobile thereupon and can be produced repeatedly and circumnutate, and also will bear bigger pulling force simultaneously.The motor of these equipment and automatically controlled 's main power line all uses Plastic-sheathed Cable at present.
Present Plastic-sheathed Cable is all by the core Shu Zucheng in outer field sheath and the sheath, and every intrafascicular core of core is made up of insulating barrier and linear conductor, passes through the insulating barrier mutually insulated between each core.This Plastic-sheathed Cable is in motor and automatically controlled moving process, motor and automatically controlled 's the power of pullling all acts on core and the sheath, because the resistance to tension of core and sheath is all relatively poor, therefore under frequent effect of moving circumnutating repeatedly of being produced and big pulling force, cable is easy to generate the conductor fracture phenomena of cut-offfing, insulate, thereby influences equipment construction personnel's safety.
Summary of the invention
The purpose of this utility model is the weak point that exists in the above-mentioned technology, and a kind of stretch-proof cable is provided, and it has the advantages that to stretch repeatedly, intensity height, good toughness.
The technical scheme that realizes the utility model purpose is as follows:
The stretch-proof cable, it comprises restrictive coating, is provided with in the restrictive coating to be provided with spring in the middle of being provided with cable core, cable core in elastic layer, the elastic layer, and cable core is made up of some stranded cores, and every core is provided with insulating barrier, tensile layer and conductor from outside to inside successively.
Described elastic layer is the king bolt spring layer.
Described tensile layer is netted steel wire floor.
The utility model has the advantages that the tensile strength that has promoted cable, can effectively avoid moving circumnutating repeatedly of being produced and conductor that big pulling force the produces fracture phenomena of cut-offfing, insulate because of frequent, thus assurance equipment construction personal security.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the stretch-proof cable, it comprises restrictive coating 1, be provided with in the restrictive coating 1 and be provided with spring 3 in the middle of being provided with cable core, cable core in elastic layer 2, the elastic layer 2, cable core is made up of some stranded cores, and every core is provided with insulating barrier 4, tensile layer 5 and conductor 6 from outside to inside successively, core comprises four among this city embodiment, elastic layer 2 is the king bolt spring layer, and tensile layer 5 is netted steel wire floor, is provided with filler between cable core and the elastic layer 2.
