Abstract
The invention discloses a self-supporting-type control cable which includes an external protective sleeve (5), and a plurality of cable cores and a reinforcement part (4), which are arranged in the external protective sleeve (5) through a buffer layer (3). The reinforcement part (4) and the cable cores are arranged in parallel in the external protective sleeve (5). Through improvement of a cable structure and the mechanical strength of a bearing element, the self-supporting cable is applicable to an electric hoist, a travelling crane and a flaw detection device; the self-supporting-type control cable can also be used for an installation system of a self-supporting hoistway or an inclined goods shelf; and super-flexible steel wires are used as a single bearing part to ensure that the cable bears the weight of the wires during installation or suspension.
Description
Technical field
The present invention relates to the construction of cable, relate 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.Although existing control cables has good electrical connection performance, because structure is comparatively complicated, weight is larger, in the time of built on stilts or unsettled laying, likely ruptures because not bearing self overall weight.
Summary of the invention
The technical problem to be solved in the present invention is, can not bear the defect of own wt etc. for prior art control cables, and a kind of self-supporting control cable is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of self-supporting control cable is provided, comprises oversheath, be located at multi-cable core and the 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 entirety.
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 invention, 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, as single bearing part, guarantees the weight that cable carries electric wire self in the time installing or hang.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, obviously, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, in accompanying drawing:
Fig. 1 is the cross sectional representation of self-supporting control cable embodiment of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, the various embodiment that below will describe will be with reference to corresponding accompanying drawing, these accompanying drawings have formed a part of embodiment, have wherein described and have realized the various embodiment that the present invention may adopt.Should understand, also can use other embodiment, or the embodiment enumerating is herein carried out to the modification on 26S Proteasome Structure and Function, and can not depart from the scope and spirit of the present invention.
In a kind of self-supporting control cable embodiment provided by the invention, as shown in Figure 1, comprise oversheath 5, be located at multi-cable core and the reinforcement 4 in oversheath 5 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 entirety 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.Meanwhile, 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 outside diameter of cable and has reduced the requirement to installing space.
Polyvinyl chloride, Polyvinylchloride, PVC, the thermoplastic resin being polymerized under 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 ℃ start to soften, and 130 ℃ become viscoelastic state, and 160～180 ℃ start to change into viscous state; There is good mechanical performance, tensile strength 60MPa left and right, impact strength 5～10kJ/m2; There are excellent dielectric property.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 declines rapidly, must add in actual applications stabilizer to improve the stability to light and heat.
Resilient coating between cable core and oversheath 6 is nonwoven fabrics, and coated a kind of yarn fabric of being made up of special material is made 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 been coated one deck sheath material, guarantees the weight that cable carries electric wire self in the time installing or hang.
The present invention, by improving the mechanical strength of the construction of cable and load bearing element, is 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 is as single bearing part, and its outside has also been coated one deck sheath material, guarantees the weight that cable carries electric wire self in the time installing or hang.
The foregoing is only preferred embodiment of the present invention, those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various changes or be equal to replacement these features and embodiment.In addition, under instruction of the present invention, can modify to adapt to concrete situation and material and can not depart from the spirit and scope of the present invention these features and embodiment.Therefore, the present invention is not subject to the restriction of specific embodiment disclosed herein, and the embodiment within the scope of all the application's of falling into claim belongs to protection scope of the present invention.
