The invention discloses a travelling cable for high-speed parallelly-connected elevators. The travelling cable comprises a cable core and an outer protective layer wrapped on the periphery of the cable core in squeezing mode, wherein the cross section of the outer protective layer is roughly oval, a first peripheral cylinder and a third pheripheral cylinder at two ends of a long axis direction of the oval cross section are respectively formed by two sections of converged minor-diameter arc cylinders, the converged portion of the two sections of converged arc cylinders form a concave, a second peripheral cylinder and a fourth peripheral cylinder at two ends in a short axis direction of the oval cross section are major diameter arc cylinders, and two ends of the major diameter arc cylinders are respectively in transition connection with a minor diameter arc cylinders. 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, specially refer 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, the used cable of elevator has its specific (special) requirements: its will be synchronized with the movement with elevator (trailing cable), the control line that had both needed the transfer control signal, also needing provides the power line of electric energy for the parts in elevator (such as the motor of switch elevator door, the ventilation fan at elevator top, the illuminating lamp in the elevator), thereby sometimes also needs video line so that the personnel in the Master Control Room can observe the situation in the elevator.
Existing elevator trailing cable is generally flat, and thinner thickness, when it uses as high speed interconnect elevator trailing cable, and owing to many ladders move in same hoistway, similar piston movement during every ladder operation, the hoistway wind-force of generation can blow trailing cable.When many elevators moved in the same way, the crossflow that produces in the hoistway can blow on the car guide rail wheel of inverted running closing on trailing cable, thereby break or break cable core, makes the elevator loss of function.Existing elevator trailing cable flexibility is relatively poor in addition, and when being squeezed, cable core easily is damaged.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of high speed trailing cable for elevator in parallel for the existing problem of existing elevator trailing cable.
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 that is extruded in described cable core periphery, it is characterized in that, the cross section of described outer jacket is substantially oblong-shaped cross section, each is made of the first, the 3rd outer rim cylinder at described elliptic cross-section long axis direction two ends two sections small diameter arc cylinders that cross, two sections circular arc cylinder intersections that cross form a depression, described elliptic cross-section short-axis direction two ends second, all round the edge cylinder be the 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 of the spaced core conductor of some rows and a load-carrying unit and two hollow gasbags of being arranged between the adjacent two winding displacement core conductors, and described core conductor, load-carrying unit and hollow gasbag are insulated layer and surround.
In a preferred embodiment of the invention, two hollow gasbags between the 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 is equidistantly arranged at interval.
In a preferred embodiment of the invention, described load-carrying unit is the aramid fiber rope.
Owing to having adopted technique scheme, the present invention compares with existing elevator trailing cable structure, has the following advantages:
1, because the cross section of outer jacket is substantially oblong-shaped cross section, thereby the thickness of trailing cable is increased, surpassed guide rail wheel gap, trailing cable of the present invention can not rolled by the guide rail wheel.
2, because the cross section of outer jacket is substantially oblong-shaped cross section, and second of described elliptic cross-section minor axis two ends, all round the edge cylinder be the large diameter circular arc cylinder, reduced the impact that cable is subjected to horizontal hoistway air-flow, under the wind-force effect, cable only can twist and can transverse shifting, and elliptic cross-section major axis two ends first, each is made of the 3rd outer rim cylinder two sections small diameter arc cylinders that cross, two sections circular arc cylinder intersections of crossing form is recessed under the vertical hoistway wind action stretching cable as two root posts, the probability of minimizing cable lateral shift.
3, the present invention arranges hollow gasbag in cable inside, has increased the flexibility of cable, has also increased the anti-pressure ability when cable is squeezed simultaneously, and when distortion of the cable, the protection cable core is without prejudice.
4, the present invention arranges many aramid fiber ropes in cable, has increased the stretching resistance of cable, adds the effect of playing tear line man-hour at cable simultaneously.
Description of drawings
Fig. 1 is the profile of high speed of the present invention trailing cable for elevator in parallel.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
As shown in Figure 1, provided the cross-sectional view of high speed trailing cable for elevator in parallel among the 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, thereby the thickness of trailing cable is increased, surpassed guide rail wheel gap, trailing cable of the present invention can not rolled by the guide rail wheel.
The outer rim cylinder 110 at elliptic cross-section long axis direction two ends, 120 respectively is made of two sections small diameter arc cylinders 111 that cross, 112 and 211,212, two sections the circular arc cylinders 111 that cross, 112 intersections form a depression 113, two sections the circular arc cylinders 121 that cross, 122 intersections form a depression 123, two places depression 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.Reduced like this impact that cable is subjected to horizontal hoistway air-flow, under the wind-force effect, cable only can twist and can transverse shifting.
Cable core is made of the equidistant core conductor 210 of arranging in eight row intervals and the load-carrying unit 220 and two hollow gasbags 231,232 that are arranged between the adjacent two winding displacement core conductors 210, and core conductor 210, load-carrying unit 220 and hollow gasbag 231,232 are insulated 240 encirclement of layer.
