Description

Elevator wire rope
Technical field
The present invention relates to a kind of elevator wire rope of super high-rise building, in particular to a kind of elevator wire rope, by Multiple steel core rope strand compositions, in the steel core of the cable wire, at least one steel are provided between core strands and outer layer strands Include to lubricate the high fibre core of oil content, therefore the characteristic of the low elongation of high resiliency can be maintained on core, oiling is enable to continue surely Surely it carries out.
Background technique
In general, metal material cable wire is widely used for including machinery, construction, ship, fishery, light industry, bridge In the extensive field such as beam, public cable car and electric power, the basic structure of such cable wire carries out as described below referring to Fig.1.
As shown, the rope strand 2 of general cable wire R, the core positioned inside or the multiple outer layers in outside to center 1 is twisted At.At this moment, each outer layer strands 2 are centered on one core wire 2a, and the plain line 2b of many stock units prolongs according to certain gradient The structure stretched, according to the construction of the direction of torsade and gradient, the number of strands of transfer and the torsade number of plies etc., according to different size It is divided into multiple types.
Cable wire R as shown in the figure, outer layer strands 2 be the structure being made of single layer or outer layer strands to have multilayer to constitute be most Universal structure.
In addition, for cable wire, there is a tension force effect based on loading along its length direction, or is connect with crust Touching is mobile formed during, formed between rope strand is mutual and the sub-thread of each stock, along with the load effect of contact friction, by Will be low in the service life for occurring metal fatigue repeatedly, and the damage of antirust Gold plated Layer is got rusty, and is occurred in order to prevent different View, carries out smearing protection using the lubricant of lubricating oil etc..
In cable wire as described above, constituting lubricating oil contained in the wirerope (rope core) of central part can have The form of oriented outer layer strands supply, the material of the steel core are divided into two major classes, the situation being made of fibers such as sisal hemps (Sisal) With the situation being made of steel core (steel core).
If cable wire uses the wirerope of the Fiber Materials, the relative amount of lubricating oil can be very high, therefore can To have the higher advantage of flexibility for making rope strand itself, but fracture loading is lower, and ductility is high, therefore mechanical characteristic value It is relatively low.
In addition, the steel core is broadly divided into representative two class: wirerope is located at the independent steel cord in cable wire center (IWRC, Independent Wire Rope Core) and independent steel cord rope strand are located at the center between on the inside of outer layer strands It installs wire rope core (CFRC, Center Fit Rope Core).Steel core of such steel core compared to the Fiber Materials, lubricating oil Content is relatively low, but cable wire is whole due to being made of epistasis material, and cutting loading is higher, and ductility is lower, cable wire Form will not deform, mechanical property is outstanding, but be suitable for the biggish purposes of tension, especially feel at ease among the above and fill wire rope core (CFRC), area of section is very wide, therefore is widely used as high level elevator cable wire.
A kind of structure is disclosed in patent the 10-1091578th, is had on the outside of the wirerope of independent steel cord (IWRC) Cable wire is formed along 6 outer layer strands, in the cable wire to the periphery side of independent steel cord IWRC wirerope for moistening The coated film that the hole that lubricating oil passes through is formed is handled, and the hole formed by the coated film in cable wire use makes lubricating oil Supply can be constantly from steel core side to outer layer strands side.
In addition, continuing to increase with nearest super high-rise building, elevator wire rope used in Super High building Demand shows ever-increasing trend.Cable wire used in Super High elevator as described above compared to existing middle layer or Cable wire used in the elevator of high-rise building, in order to ensure the safety of long-play distance, compared to existing cable wire, It is required that having higher safety coefficient and coefficient of elasticity and lower ductility, and require with fast state long-play When can also will be used to maintain upper and lower elevator taking sense vibration minimize quality characteristic.
Summary of the invention
(solving the problems, such as)
It is an object of the present invention to the existing Super High mansion elevator cable wire be solved the problems, such as, to provide one Kind elevator wire rope, maintains high resiliency, low ductility characteristic using independent steel cord (CFRC) structure of steel pole, it is contemplated that steel The use condition of rope and the content of lubricating oil can be made suitably to be changed.
(means solved the problems, such as)
In general, the elevator of super high-rise building, since the speed of service is very fast, the content of lubricating oil is lower to be prevented from lubricating Be advantageous for the aspect that oil disperses etc., but lubricating oil content it is relatively fewer can have an impact to the service life of cable wire, because This just needs periodically to carry out inspection and maintenance and oiling again.
Therefore, the present invention had not only had high resiliency but also by low elongation characteristic independent steel cord (CFRC) structure of steel pole institute structure At cable wire in, be applicable in the fibre core of lubricating oil contained by independent steel cord (CFRC) steel core center, therefore in contrast to existing Independent steel cord (CFRC) wirerope, the internal lubrication oil with higher amount, when cable wire is used by inside cable wire It flows out lubricating oil gradually, so as to prevent the too early depleted of lubricating oil, the quality of metal fatigue is maintained, in technology There is the feature for reducing the necessity of oiling again in characteristic.
Basic structure setting of the present invention is based on such as flowering structure: around the center rope strand being made of 36 single cords, The outer layer strands for having 26 sub-threads to constitute, share 10 and extend around it, and these center rope strands and outer layer strands it Between there are also independent steel cord (CFRC) wirerope for being made of 7 sub-threads, share 10.
Wire rope structure: 10 × 26 (outer layer strands)+1 × 36 (center rope strands)+10 × 7 (wirerope)
Above structure is shown in Fig. 2, as shown in Fig. 2, the outside for the center rope strand 10 being made of 36 sub-threads, is extended with 10 outer layer strands 20 being made of 26 sub-threads at the space between the center rope strand 10 and outer layer strands 20, have by 7 lists Structure existing for 7 wirerope 30 of stock composition.
The present invention passes through the center of more than one wirerope in the cable wire of the independent steel cord (CFRC) structure The structure that sub-thread is made of synthetic fibers, and reach the purpose of the invention.
The synthetic fibers for forming wirerope center sub-thread are preferably polypropylene (PP), in such synthetic fibers material Heart sub-thread (fibre core) according to use condition, suitable for 7 strand wires at least some.But according to different situations, It can also be by 7 wirerope all using the fibre core of the synthetic fibers (PP) material.
Range of the lubrication oil content of cable wire of the invention between 1.2~2.0%.
(The effect of invention)
The mechanical property that wire rope core (CFRC) possesses is installed centered on elevator wire rope of the invention, can not only be maintained high Elastic and low ductility, can also have makes to lubricate the increased advantage of oil content.
Also, cable wire of the invention have the advantage that by wirerope (RC) center insertion be coated with oil The number of fibre core (PP) changes, so that it may easily adjust the content progress of target lube manually, make containing for lubricating oil Buret reason and adjustment operation become more easily.
