The travelling cable for high-speed parallelly-connected elevators has the advantages of being simple in structure, ingenious in design, capable of being effectively prevented from generating cross moving caused by wind power of a well.
Description
Technical field
The present invention relates to field of cables, specifically, be related specifically to a kind of high speed trailing cable for elevator in parallel.
Background technology
Along with emerging in multitude of skyscraper, elevator is widely used, elevator cable used has its particular/special requirement: it will be synchronized with the movement (trailing cable) with elevator, both the control line of transfer control signal had been needed, also need the power line for providing electric energy to the parts (illuminating lamp in the motor of such as switch elevator door, the ventilation fan at elevator top, elevator) in elevator, sometimes also need video line thus make the personnel in Master Control Room can observe situation in elevator.
Existing elevator trailing cable is generally flat, and thinner thickness, and when it uses as high speed interconnect elevator trailing cable, because multiple stage ladder runs in same hoistway, similar piston movement when every platform ladder runs, the hoistway wind-force of generation can blow trailing cable.When multiple elevator is run in the same way, the crossflow produced in hoistway, can blow to closing on trailing cable on the car guide rail wheel of inverted running, thus break or break cable core, make elevator loss of function.Existing elevator trailing cable flexibility is poor in addition, and when depressed, cable core is easily damaged.
Summary of the invention
Technical problem to be solved by this invention is for the problem existing for existing elevator trailing cable and provides a kind of high speed trailing cable for elevator in parallel.
Technical problem solved by the invention can realize by the following technical solutions:
High speed trailing cable for elevator in parallel, comprise cable core and the outer jacket being extruded in described cable core periphery, it is characterized in that, the cross section of described outer jacket is substantially oblong-shaped cross section, first of described elliptic cross-section long axis direction two ends, the small diameter arc cylinder that 3rd outer rim cylinder respectively crosses by two sections is formed, two sections of circular arc cylinder intersections crossed form a depression, second of described elliptic cross-section short-axis direction two ends, 4th outer rim cylinder is large diameter circular arc cylinder, the two ends of large diameter circular arc cylinder are connected with a small diameter arc cylinder arc transition respectively.
In a preferred embodiment of the invention, described cable core is made up of some rows spaced core conductor and the load-carrying unit be arranged between adjacent two winding displacement core conductors and two hollow gasbags, described core conductor, load-carrying unit and hollow gasbag surround by insulating barrier.
In a preferred embodiment of the invention, two hollow gasbags between described adjacent two winding displacement core conductors are symmetricly set on described load-carrying unit both sides.
In a preferred embodiment of the invention, described core conductor equidistant arrangement at interval.
In a preferred embodiment of the invention, described load-carrying unit is aramid fiber rope.
Owing to have employed technique scheme, the present invention, compared with existing elevator trailing cable structure, has the following advantages:
1, because the cross section of outer jacket is substantially oblong-shaped cross section, thus the thickness of trailing cable is increased, exceeded guide rail wheel gap, trailing cable of the present invention can not be rolled by guide rail wheel.
2, cross section due to outer jacket is substantially oblong-shaped cross section, and second of described elliptic cross-section minor axis two ends, 4th outer rim cylinder is large diameter circular arc cylinder, decrease the impact of cable by horizontal hoistway air-flow, under wind-force effect, cable only can twist and can not transverse shifting, and first of elliptic cross-section major axis two ends, the small diameter arc cylinder that 3rd outer rim cylinder respectively crosses by two sections is formed, under vertical hoistway wind action that what two sections of circular arc cylinder intersections of crossing were formed be recessed in as two root posts stretching cable, reduce the probability of cable lateral shift.
3, the present invention arranges hollow gasbag in cable inside, adds the flexibility of cable, too increases anti-pressure ability when cable is squeezed simultaneously, and when distortion of the cable, protection cable core is without prejudice.
4, the present invention arranges many aramid fiber ropes in the cable, adds the stretching resistance of cable, adds the effect playing tear line man-hour at cable simultaneously.
Accompanying drawing explanation
Fig. 1 is the profile of high speed of the present invention trailing cable for elevator in parallel.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
As shown in Figure 1, the cross-sectional view of high speed trailing cable for elevator in parallel is given in figure, as can be seen from the figure, this high speed trailing cable for elevator in parallel comprises cable core and is extruded in the outer jacket 100 of cable core periphery, the cross section of this outer jacket 100 is substantially oblong-shaped cross section, thus the thickness of trailing cable is increased, exceeded guide rail wheel gap, trailing cable of the present invention can not be rolled by guide rail wheel.
The outer rim cylinder 110,120 at elliptic cross-section long axis direction two ends is respectively made up of two sections of small diameter arc cylinders crossed 111,112 and 211,212, the two sections of circular arc cylinder crossed 111,112 intersections form a depression 113, the two sections of circular arc cylinder crossed 121,122 intersections form a depression 123, two places' depressions 113,123 under vertical hoistway wind action as two root posts stretching cable, the probability of minimizing cable lateral shift.
The outer rim cylinder at elliptic cross-section minor axis two ends is large diameter circular arc cylinder 130,140, the two ends of large diameter circular arc cylinder 130 are connected with small diameter arc cylinder 111,121 arc transition respectively, and the two ends of large diameter circular arc cylinder 140 are connected with small diameter arc cylinder 112,122 arc transition respectively.Which reduce cable by the impact of horizontal hoistway air-flow, under wind-force effect, cable only can twist and can not transverse shifting.
Cable core is made up of the core conductor 210 of eight row's interval equidistant arrangement and the load-carrying unit 220 be arranged between adjacent two winding displacement core conductors 210 and two hollow gasbags 231,232, core conductor 210, load-carrying unit 220 and hollow gasbag 231,232 surround by insulating barrier 240.
Every winding displacement core conductor 210 is arranged by three core conductor 211 parallel interval and forms; two hollow gasbags 231,232 between adjacent two winding displacement core conductors 210 are symmetricly set on both sides before and after load-carrying unit 220; which increase the flexibility of cable; too increase anti-pressure ability when cable is squeezed simultaneously; when distortion of the cable, protection cable core is without prejudice.
Load-carrying unit 220 is aramid fiber rope, which increases the stretching resistance of cable, adds the effect playing tear line man-hour at cable simultaneously.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
