Description

A kind of high intensity high flexibility cable for elevator

Technical field

This utility model relates to a kind of cable, is specifically related to a kind of high intensity high flexibility cable for elevator.

Background technology

Elevator is a kind of goods vertical transport equipment being widely used, main by motor driving oil pump, relies on oil Cylinder drives heavy-duty chain to drive hydraulic lifting.Owing to using hydraulic pressure as lifting drive, there is the spies such as loading capacity is big, lifting is steady Point, is widely used in transport vertical with the goods building between high level.

Elevator cable not only through electric current, and still suffers from own wt and certain pulling force in running； Cable lifting following falling unit lifts, and flexion torsion is many, the cable discontinuity of different azimuth, produces internal stress, is very easy to make Becoming cable breakdown, and be stuck on the elevating mechanism of elevator, impact runs.Cable once ruptures, and can bring about and compares Serious potential safety hazard.

Utility model content

For solving the problems referred to above that prior art exists, it is an object of the invention to provide a kind of tension disconnected, resistance to bend around, strong Spend high cable for elevator.

For solving above-mentioned technical problem, this utility model be the technical scheme is that

A kind of high intensity high flexibility cable for elevator, including the cable core by some insulated wire cores strand system；Described absolutely Edge core includes being positioned at the conductor at center, being looped around the insulating barrier outside conductor and the first braid；In the outside of cable core successively It is provided with enhancement Layer, the second braid and oversheath；It is provided with at the gap of insulated wire cores center and insulated wire cores two-by-two Reinforcement.

Further improvement of the utility model is: described conductor is tinned copper wire conductor.Described conductor is by tin-coated copper The multi-core conductor that tow closes.

Further improvement of the utility model is: described insulating barrier is ethylene propylene diene rubber insulation, its thickness is 0.8 ~ 2.0mm；Described first braid is that aramid fiber silk braiding one layer forms；Described reinforcement is steel reinforcement.

Further improvement of the utility model is: described enhancement Layer is that aryl fiber cloth overlap is wrapped to be formed, its thickness For 0.2mm；Described second braid is that aramid fiber weaves or braided steel wire forms, and its count is 80%；Described oversheath For chloroprene rubber sheath, its thickness is 1.8 ~ 3.8mm.

Owing to have employed technique scheme, the technological progress that this utility model obtains is:

This utility model provides a kind of high intensity high flexibility cable for elevator, reasonable in design, have high intensity, Wear-resisting, resistance to bend around the disconnected feature of, tension, be suitable for flexion torsion, be not susceptible to fracture；Good insulating, is not susceptible to electric leakage existing As, it is highly suitable as elevator cable and uses, it is possible to significantly reduce cable replacement frequency.This utility model simple in construction, property Can be stable, manufacture process is simple, with low cost, it is not necessary to special installation, it is simple to industrialization promotion.

Some steel reinforcements it are provided with, it is possible to bear bigger pressure and pulling force, bending effect in this utility model Good, it is difficult to be broken off, intensity is high；And in moving process, protect the conductors from abrasion.First braid of the present utility model, Enhancement Layer, the second braid are effectively increased pull-off force and the pliability of cable, prevent insulated wire cores impaired so that cable is more Being easy to mobile, toughness foot, not easy fracture, ageing resistace is strengthened, is significantly improved the service life of cable.

This utility model oversheath has good mechanical performance, enhances the intensity of cable, wearability and weatherability, has Conductor in effect protection cable.

Detailed description of the invention

Describe this utility model below with reference to the accompanying drawings in detail.

A kind of high intensity high flexibility cable for elevator, as it is shown in figure 1, include cable core.Described cable core is by four covered wires Core strand system forms；Insulated wire cores includes being positioned at the conductor 11 at center, being looped around the insulating barrier 12 outside conductor 11 and the first braiding Layer 13.Described conductor 11 is tinned copper wire conductor, and the sectional area of conductor can be adjusted according to actual current throughput；Described absolutely Edge layer 12 insulate for ethylene propylene diene rubber, and its thickness is 0.8 ~ 2.0mm；Described first braid 13 weaves one for aramid fiber silk Layer forms, and count is 80%.It is provided with reinforcement 2 at the gap of insulated wire cores center and insulated wire cores two-by-two, described Reinforcement 2 is steel reinforcement；Five reinforcements 2 are set the most altogether.

Enhancement Layer the 3, second braid 4 and oversheath 5 have been orderly arranged outside each it at cable core.Described enhancement Layer 3 is aramid fiber Fiber cloth overlap is wrapped to be formed；Described second braid 4 forms for aramid fiber braiding or braided steel wire, and count is 80%； Described oversheath 5 is chloroprene rubber sheath, and thickness is 1.8 ~ 3.8mm.

When preparing cable, outside conductor, first extrude insulating barrier, weave one layer of aramid fiber silk again, make insulated wire cores； Use cable-former that together with five reinforcements, four insulated wire cores are twisted into cable core, overlapping wrapped aramid fiber outside cable core Cloth, then weave aramid fiber or steel wire, outside the second braid, finally extrude chloroprene rubber sheath, obtain high intensity high flexibility Cable for elevator.

The foregoing is only preferred embodiment of the present utility model, all according to this utility model claim done equal Deng change and modification, covering scope of the present utility model all should be belonged to.
