Abstract
The utility model relates to a reinforced fiber flat cable used for an elevator, belonging to an H01B type cable technique. The utility model consists of an insulation layer core extruded from a twisted soft conductor, a reinforced core and an elastic protection coat. The utility model is characterized in that the reinforced core on two sides of the flat cable is a reinforced fiber core which consists of a central bundle formed by a plurality of high tenacity polypropylene threads, an inner core formed by a plurality of Kevlar bundles combined by a plurality of Kevlar threads and a plurality of polyester bundles combined by a plurality of polyester threads through weaving, and then a PVC protection layer is extruded. The utility model has light weight and better flexibility, and the utility model has small bending radius which is difficult to cause torsion, and simulated life is more than 3 million times according to a bending test with high reliability. The utility model can be widely applied to a control system of a high speed elevator in high buildings.
Description
Technical field
The utility model belongs to H01B class cable technology, particularly relates to the fiber reinforced flat cable of a kind of elevator.
Background technology
Present known elevator control flat cable is the stube cable that is used between elevator car and the machine room control cubicle, follows elevator to move up and down, and is the artery of control elevator motion.Usually elevator control flat cable adopts steel wire rope to do strengthening core, is used to carry the weight of operation elevator cable.Because the deadweight of steel wire rope proportion ambassador cable increases, steel wire rope is harder in addition, if the filament diameter minimum for 0.2mm in processing or in continuous crooked use, there is one to have fracture just might bring disaster to adjacent insulated wire cores to influence cable useful life.
Summary of the invention
The utility model provides elevator fiber reinforced flat cable for solving the problem that existing known technology exists.
The utility model provide a kind of softness, reliable, be applicable to the elevator control flat cable that high-rise express elevator needs.
The purpose of this utility model is achieved in that
Determine the minimum Fracture Force of strengthening core of its needs carrying that is in operation according to the weight of cable, choose the aramid fiber silk of appropriate size, weave the formation inner core with auxiliary material dacron thread etc., extrude the polyvinyl chloride sheath again, fiber strengthening core symmetry is positioned over the insulated wire cores both sides that flat shape is arranged, extrudes cable cover(ing).
The utility model adopts following technical scheme:
Elevator is extruded the insulating barrier core with fiber reinforced flat cable by stranded flexible conductor, and strengthening core, elasticity protective jacket constitute, and the strengthening core that is characterized in the flat cable both sides is the fiber strengthening core.
The utility model can also adopt following technical measures:
The fiber reinforced flat cable of above-mentioned elevator, be characterized in the constituting of fiber strengthening core of flat cable both sides, by several polypropylene strength fibres is that several Shu Dilun bundles that several Shu Fanglun tow of forming of central beam, several aramid fiber silks and several dacron threads are formed are woven together and form inner core, squeezes the PVC sheath again.
The fiber reinforced flat cable of above-mentioned elevator is characterized in that the polypropylene strength fibre bundle number of fiber strengthening core is 1-2, and aramid fiber tow number is 2-6, and terylene bundle number is 2-10.
Description of drawings
Fig. 1 is the utility model cross section structure schematic diagram.
Fig. 2 is the structural representation of fiber strengthening core among Fig. 1.
Advantage and the good effect that the utlity model has be, product weight is light, flexibility good, Bending radius little being difficult for reversed, and bend test (test agree life) is greater than 3,000,000 times, The reliability height. Can be used for the high-rise high speed apparatus for controlling elevator.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following example now, and conjunction with figs. is described in detail as follows:
Embodiment
With reference to accompanying drawing 1 and accompanying drawing 2, elevator is the reinforced flat cables of 20 core fibres with fiber reinforced flat cable, and 1 extrudes polyvinyl chloride for copper conductor constitutes cable insulation core, the 2nd, fiber strengthening core.The polypropylene tow 4 that the fiber strengthening core is formed with 400 dawn polypropylene strength fibres is the 3 bundle aramid fiber tow 5 formed of central beam, 2400 dawn aramid fiber silks and 8 thin polyester threads 6 formation inner core that is woven together, crowded again PVC sheath 7.Copper conductor cable insulation core 1 and fiber strengthening core 2 are extruded polyvinyl chloride elastic body jacket 3 and are constituted the fiber reinforced flat cable of elevator.
Because the utility model has adopted aramid fiber silk strengthening core that product weight is alleviated in elevator control flat cable, flexibility is better, 15 ℃ of torsional deflection ∠ have improved the reliability of elevator cable, also provide assurance for the easy for installation of elevator cable and elevator even running simultaneously.
Claims (3)
