Abstract
The utility model discloses a self-supporting control cable which comprises an oversheath (5), a plurality of cable cores and a reinforcing member (4) which pass through a buffer layer (3) and are disposed in the oversheath (5), wherein the reinforcing member (4) and the cable cores are disposed in the oversheath (5) in a parallel way. By improving mechanical strength of the cable structure and bearing elements, the self-supporting control cable is applied to electric hoists, vehicles and flaw detection equipment, and also can be used as a self-supporting control cable using in installation systems for self-supporting hoistway or tilting shelves. Super-flexible steel wires are used as a single bearing part, to ensure that the cable can bear the weight itself during installation or suspension.
Description
Technical field
The utility model relates to the construction of cable, relates in particular to a kind of self-supporting control cable.
Background technology
Control cables generally comprises: center copper cash (solid wire of sub-thread or stranded wire), plastic insulation.Be electrically connected preferably performance although existing control cables has, because structure is comparatively complicated, weight is larger, when built on stilts or unsettled laying, might rupture because not bearing self overall weight.
The utility model content
The technical problems to be solved in the utility model is, can not bear the defective of own wt etc. for the prior art control cables, and a kind of self-supporting control cable is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of self-supporting control cable is provided, comprises oversheath, be located at multi-cable core and reinforcement in oversheath by resilient coating; Reinforcement is parallel with cable core in oversheath.
Preferably, the quantity of described cable core is eight, and eight cable cores are stranded according to the general layout layer-twisted type of 1+7 is an integral body.
Preferably, described cable core comprises the insulating barrier of conductor and coating conductor.
Preferably, described conductor is that the thin strand of multiply and essence are twisted into the thin one-level copper free wire of bundle.
Preferably, the material of described insulating barrier is polyvinyl chloride.
Preferably, described cable core is colored core or coding core.
Preferably, described resilient coating is nonwoven fabrics.
Preferably, described reinforcement is flexible steel wire.
Preferably, the external diameter of described flexible steel wire is 2.0mm-3.0mm, is preferably 2.8mm.
Implement self-supporting control cable of the present utility model, have the following advantages or beneficial effect: by improving the mechanical strength of the construction of cable and load bearing element, be applicable to electric block, driving and defect-detecting equipment, also can make the self-supporting control cable of the installation system use of self-bearing type hoistway or tilting shelf.Super flexible steel wire guarantees the weight of cable carrying electric wire self when installing or hang as single bearing part.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, during the below will describe embodiment, the accompanying drawing of required use is done simple the introduction, obviously, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, in accompanying drawing:
Fig. 1 is the cross sectional representation of the utility model self-supporting control cable embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, the various embodiment that hereinafter will describe will be with reference to corresponding accompanying drawing, these accompanying drawings have consisted of the part of embodiment, have wherein described the various embodiment that realize that the utility model may adopt.Should understand, also can use other embodiment, the embodiment that perhaps this paper is enumerated carries out the modification on 26S Proteasome Structure and Function, and can not break away from scope of the present utility model and essence.
In a kind of self-supporting control cable embodiment that the utility model provides, as shown in Figure 1, comprise oversheath 5, be located at oversheath 5 interior multi-cable core and reinforcement 4 by resilient coating 3; Reinforcement 4 is arranged in oversheath 5 abreast with cable core.
Wherein, the cable core radical in the present embodiment is preferably eight, and it is an integral body that these eight cable cores carry out layer-twisted type stranded according to the general layout of 1+7, guarantees the roundness of core wires.This cable core comprises the insulating barrier 2 of conductor 1 and coating conductor 1.Conductor 1 twists for multiply is thin and essence is twisted into the thin one-level copper free wire of bundle.Simultaneously, insulating barrier 2 is polyvinyl chloride (PVC) material, and preferred insulative material adopts high-quality PVC compound, is designed to colored core or coding core, has reduced the requirement of outside diameter of cable reduction to installing space.
Polyvinyl chloride, Polyvinylchloride, PVC, the thermoplastic resin that is polymerized under the initator effect by vinyl chloride.Be the homopolymers of vinyl chloride, ryuron and vinyl chloride copolymer are referred to as vinyl chloride resin.PVC is the white powder of impalpable structure, and the degree of branching is less.Industrial PVC molecular weight generally in 50,000～120,000 scopes, has larger polydispersity, and molecular weight increases with the reduction of polymerization temperature; Without definite melting point, 80～85 ℃ begin to soften, and 130 ℃ become the viscoelastic attitude, and 160～180 ℃ begin to change into viscous state; Mechanical performance is preferably arranged, about tensile strength 60MPa, impact strength 5～10kJ/m2; Excellent dielectric property are arranged.But to the poor stability of light and heat, more than 100 ℃ or through long-time exposure in sunshine, will decompose and produce hydrogen chloride, and further autocatalysis is decomposed, cause variable color, physical and mechanical properties also descends rapidly, must add in actual applications stabilizer to improve the stability to light and heat.
Resilient coating between cable core and oversheath 5 is nonwoven fabrics, namely coats a kind of yarn fabric of being made by special material and makes resilient coating and bearing bed, mechanical shock beyond can effectively keeping out like this.
In addition, the super flexible steel wire that reinforcement 4 is, external diameter can be 2.0mm-3.0mm, is preferably 2.8mm in the present embodiment.This super flexible steel wire that serves as reinforcement 4 is as single bearing part, and its outside has also coated one deck sheath material, guarantees the weight of cable carrying electric wire self when installing or hang.
The utility model is applicable to electric block, driving and defect-detecting equipment by improving the mechanical strength of the construction of cable and load bearing element, also can make the self-supporting control cable of the installation system use of self-bearing type hoistway or tilting shelf.Super flexible steel wire is as single bearing part, and its outside has also coated one deck sheath material, guarantees the weight of cable carrying electric wire self when installing or hang.
The above is only preferred embodiment of the present utility model, and those skilled in the art know, in the situation that do not break away from spirit and scope of the present utility model, can carry out various changes or be equal to replacement these features and embodiment.In addition, under instruction of the present utility model, can modify to adapt to concrete situation and material and can not break away from spirit and scope of the present utility model these features and embodiment.Therefore, the utility model is not subjected to the restriction of specific embodiment disclosed herein, and all interior embodiment of claim scope that fall into the application belong to protection range of the present utility model.
