Description
Technical field
The present invention relates to traction elevator and compensate system, in particular it relates to a kind of compensating cable of elevator.
Background technology
The effect of compensating cable of elevator is the moment variations eliminating or reducing on the traction sheave caused owing to the length of suspension strop and trailing cable changes in running process of elevator.
Traditional compensated chain is loop chain, is installed with the rope of the soft fibre such as cotton, fiber crops establishment in chain link.The effect of rope is to reduce the noise that when elevator runs, chain sends, and avoids chain to tie a knot.Though it has the advantage that price is low, but not easily leads, and when elevator speed is higher, noise and knotting phenomenon still cannot be avoided, so being normally only used for the low speed ladder of speed≤2m/s.
The elevator of speed >=2.5m/s substantially adopts at present and compensates rope.The diameter compensating rope selects according to the multiplying power of the diameter of suspension strop and assembly pulley: when pulley block ratio is 1, compensates the diameter of rope close to suspension strop diameter；When pulley block ratio is 2, compensate the diameter of rope more than suspension strop diameter.This allows for designer and the regulating wheel that quality is very big must be adopted to compensate rope with tensioning, causes compensating rope system structure complicated, and price is high.
1988, Xi Ke company of the U.S. (SiecorCorporation) is proposed a kind of Whisperflex (this pool good fortune Simon Rex of prestige) compensated cable (U.S. Patent number: 4,724,929), the cross section of this compensated cable is circular or pancake, as seen in figure la and lb.This compensated cable includes chain (or rope) 1, mixed with plastics (or rubber) core 2 of metallic particles and outside plastics (or rubber) sheath 3.Owing to metallic particles (is of a size of 0.02～0.04 inch relatively greatly, i.e. 0.51～1.02mm), and the adhesion of itself and plastics (or rubber) is little, for avoiding metallic particles to come off, and improving the outward appearance of compensated cable, sheath 3 is the indispensable ingredient of this compensated cable.This compensated cable can eliminate noise better, and the chain link of chain 1 is without knotting.Further, since core 2 is mixed with metallic particles, the linear mass of compensated cable can be increased, thus the comparable traditional compensated chain (rope) of diameter of chain link (or steel wire rope) is smaller.Meanwhile, cross section is circular or pancake is so as to easily lead, and the probability clashing into hoistway reduces, and rocking of pancake compensated cable is also less.
On this basis, also create numerous similar products, as application number be 03131665, name be called that the patent of invention of " Elevator balance compensation chain and Manufacture Method " discloses the technical scheme of similar compensated chain, structure and shape also as seen in figure la and lb.
But, above-mentioned compensated cable is to develop on the basis of original compensated chain and compensation rope, the loop chain of its core or being closely sized to original compensated chain and compensating rope of steel wire rope, periphery but adds plastics (or rubber) core 2 mixed with metallic particles and plastics (or rubber) sheath 3, thus its deadlock is much larger than traditional compensated chain, natural torsion radius increases, and natural torsion radius is with variation of ambient temperature (temperature is low, and natural torsion radius becomes big).Though additionally, the circular compensated cable in this kind of compensated cable avoids chain link knotting, but can twist.
Due to the existence of above two phenomenon, thus this compensated cable draw sometimes the parts in bad elevator pit or it drawn bad by the parts in elevator pit.
Therefore, this compensated cable result of use and not as it is contemplated that thus be still only used for slower elevators.
" compensating weight and elevator device " patent of invention that Authorization Notice No. is CN1220617C that Detweiler joint-stock company of Switzerland proposes is proposed another kind of compensated cable, and in patent, the text is as follows for claim 1:
" compensating weight of the hawser form that a kind of length for elevator device extends, including:
At least one bearing part,
The flexible sheath that one length extends, and
At least one weighted item, wherein weighted item comprises plastics with density equal to or more than 2.3g/cm3Granulated metal salt and granulated metal sulfide both at least one mixture."
The content of claim 8 and 9 is comprehensively as follows:
Its epitheca includes density equal to or more than 2.3g/cm3Slaine and metal sulfide both at least one, quantitative range is from 20% weight to 40% weight, and percentage ratio is relative to whole epitheca weight.
The patented product is not sold in China by Detweiler joint-stock company, can only be analyzed according to this patent document at present:
Claim 1 according to this patent, this product has epitheca, bearing part and three ingredients of weighted item.According to this patent specification, weighted item is frangible, it is possible to crack allowance exists, all the more so when dynamic bending, so epitheca is the required ingredient maintaining this product globality.Correspondingly, this process of producing product is complex.According to Claim 8, at least one in both slaine and metal sulfide in epitheca, its weight and whole epitheca weight ratio are 20～40%.This patent document not illustrating, what load is the load that bearing part bears be.
