Abstract
The present invention relates to a compensating cable for elevator. It is characterized by that the described compensating cable is made into flat form, its core portion has several steel wire ropes for bearing load and its exterior is covered with soft plastics containing metal granules or metal powder. Besides, its exterior also can be covered with soft plastics containing no metal granules or metal powder.
Description
Technical field
The present invention relates to traction elevator, relate in particular to the elevator compensating system.
Background technology
The effect of compensating cable of elevator is the moment variations of eliminating or reducing in the running process of elevator on the traction sheave that the length variations owing to suspension strop and trailing cable causes.
Traditional compensated chain is a loop chain, is installed with the rope of soft fibre establishments such as cotton, fiber crops in the chain link.The effect of rope is the noise that chain sends when reducing the elevator operation, and avoids the chain knotting.Though it has the low advantage of price, be difficult for guiding, and elevator speed is when higher, noise and knotting phenomenon still can not be avoided, so generally only be used for the low speed ladder.
U.S. Xi Ke company (Siecor Corporation) has released a kind of Whisperflex (this pool good fortune Simon Rex of prestige) compensated chain many years ago, and the cross section of this compensated chain is circular.On this basis, numerous similar products have also been produced, disclose the technical scheme of similar compensated chain as the patent of invention that application number is 03131665, name is called " Elevator balance compensation chain and Manufacture Method ", as shown in Figure 1, this compensated chain comprises chain 3, core 2 and the outside sheath 1 that is provided with, it can eliminate noise better, and the chain link of chain 3 can not tied a knot yet.In addition, because core 2 is mixed with metallic particles, can increase the linear mass of compensated chain, thereby the comparable traditional compensated chain of diameter is smaller.Simultaneously, cross section is that circle makes it easy guiding, and the possibility of bump hoistway reduces.
Yet the deadlock of this compensated chain is much larger than traditional compensated chain, and the natural torsion radius increases, and the natural torsion radius is with variation of ambient temperature (temperature is low, and it is big that the natural torsion radius becomes).In addition, though this compensated chain has been avoided the chain link knotting, can twist.
Because the existence of above-mentioned two kinds of phenomenons, so that this compensated chain draws the interior parts of bad elevator pit or it to be broken by the parts in the elevator pit sometimes.
Therefore, the result of use of this compensated cable also is not so good as anticipation, thereby still can only be used for slower elevators.
Summary of the invention
For addressing the above problem, the present invention aims to provide that a kind of flexibility is good, the natural torsion radius is little and can eliminate the compensating cable of elevator of compensated cable twisted phenomena.
A kind of compensating cable of elevator provided by the present invention is characterized in that: described compensated cable is flat, and its core has some steel wire ropes of bearing load, and its periphery is the flexible plastic that contains metallic particles or powder.
In above-mentioned compensating cable of elevator, its outside also can be surrounded by the flexible plastic that does not contain metallic particles or powder again.
Owing to adopted above-mentioned technical solution, the present invention replaces chain as force-summing element with seizing wire, and steel wire rope is surrounded by the plastics of gold doping metal particles or powder outward to improve the quality of unit length compensated cable.It no longer is a compensated chain, but a kind of new product between compensated chain and compensation rope.The present invention changes seizing wire into owing to force-summing element, thereby makes it can do to become band, and its profile such as flat cable are so be called compensated cable.Banded compensated cable flexible good, the natural torsion radius is little, and can eliminate the twisted phenomena of compensated cable.Simultaneously, banded compensated cable can teeter, and it is more simple to lead.The present invention can be as compensated chain without tensioning, but rocking during the elevator operation is littler than compensated chain, thereby is expected to be used for the higher elevator of speed.
Description of drawings
By the description of a following embodiment to compensating cable of elevator of the present invention, can further understand purpose of the present invention, specific structural features and advantage in conjunction with its accompanying drawing.Wherein, accompanying drawing is:
Fig. 1 is the schematic cross-section of existing compensated chain;
Fig. 2 is the schematic cross-section of compensating cable of elevator first embodiment of the present invention;
Fig. 3 is the schematic cross-section of compensating cable of elevator second embodiment of the present invention.
The specific embodiment
Referring to Fig. 2, embodiment of the present invention one, this scheme are base forms of the present invention.
This compensating cable of elevator is flat, its inside have several seizing wires 1 ', the specification of steel wire rope, diameter and quantity are according to the concrete specification decision of compensated cable;
Steel wire rope 1 ' the periphery be the plastics 2 that contain metallic particles or powder ', its proportioning is also according to the concrete specification decision of compensated cable.
Referring to Fig. 3, embodiment of the present invention two, this scheme are optimization forms of the present invention.The difference of scheme two and scheme one be the outermost layer of scheme two be not containing metal particle or powder plastics 3 ', can protect core, and improve the outward appearance of compensated cable, reduce the sassafras that rubs between compensated cable and the guider, thereby reduce wear.
Noise source when in sum, the invention enables compensated cable can not become the elevator operation.Because steel wire rope is very thin, the thickness of compensated cable is little, thereby compensated cable is flexible fine.Simultaneously, because compensated cable is flat, so compensated cable can natural distortion, guiding easily, and transverse shakiness is very little.
Though compensating cable of elevator of the present invention is described with reference to current instantiation, but those skilled in the art should be realized that, above example only is to be used for illustrating the present invention, also can make the variation and the modification of various equivalences under the situation that does not break away from spirit of the present invention.Therefore, if in connotation scope of the present invention to the variation of above-mentioned example, modification all will drop in the scope of claims of the present invention.
