Description
Technical field
The present invention relates to elevators field, a kind of lifting steel band that can realize enhanced feature, this lifting steel band is main
As elevator traction, carry, hang and promote assembly and use.
Background technology
Elevator is as a kind of vertical transport instrument, closely bound up with modern society life, along with socioeconomic development and
The quickening of urbanization process, makes high-rise get more and more, and high-rise has become the mark in a city, has
A little terrestrial references even becoming city.Along with appearance and the socio-cultural development of high-rise, the demand for elevator is more
Coming the most powerful, especially into today of social senilization, the meaning of elevator is the most great.Global elevator every day
All in operating, carry the transport of substantial amounts of artificial abortion and logistics, the effect that elevator undertakes between floors has become to weigh very much
Want, be modern society's indispensable part of life.
Traditional elevator mainly uses steel wire rope as traction and the carrier of hanging, and steel wire rope serves not only as safety component,
Carry the weight of car and counterweight, especially as the carrier of traction, drive lift car to operate up and down.Steel wire rope is as elevator
Vitals has been used many years, but its shortcoming is also very it will be evident that steel wire rope has rolled steel dosage greatly, easily
Abrasion, discontinuity, need to lubricate, can get rusty, maintain the shortcomings such as trouble, installation requirement are high.Therefore, along with elevator technology
Development, occurred in that by the trend promoting steel band and replacing steel wire rope, and would is that main flow future, the advantage promoting steel band is
Steel wire rope is incomparable, and certainly promoting steel band also has its shortcoming, such as promotes the easy sideslip of steel band left and right migration, causes elevator
Vibration produces noise, the most also exacerbates the abrasion promoting steel band.
For avoid promote steel band deviation on pulley, existing pulley such as Chinese patent 00805967.5 and
201020530296.5, national standard (standard No. is GB/T11358-1999) etc. are all partial to use drum type groove 8a(such as Fig. 1),
Chinese patent 200480043744.6 uses concave slot 8b(such as Fig. 2), this kind of grooved has tangential force to produce, thus ensures to promote steel
Band 22 ' moves at Lun Shangxiang center.But so the internal stress causing band middle part is more than both sides, and traditional flat rubber belting
Universal flakiness ratio is bigger, and internal stress obtains cambic release at width.But the width of the band used on elevator
Smaller with thickness ratio, use such technical scheme, promote steel band mid portion stress to promote bottom steel band greatly compared with periphery
The be squeezed cover layer at top of cover layer be then stretched, steel band discontinuity, easily cause lifting steel band cover layer and open
Split and make steel band damage, and when passing in and out wheel, wheel face contacts can experience section flexure with promoting steel band, when not contacting outside
Power disappears, and band reverts to plane, and internal stress change the most drastically, exists flexural fatigue phenomenon, and number of run reaches certain journey
Degree, inner wire wire rope core occurs separating with integument, causes middle part to be ftractureed, then promote steel band and scrap, and service life reduces.
For current production technology, the cost promoting steel band is the highest, and about 8～10 times of steel wire rope cost, therefore should fill
Divide the service life considering to promote steel band.
Also there are some to be designed with concaveconvex shape and promote steel band, such as Chinese patent 200810061529.9, it is simply that carrying
Rise steel band to make in shape to change, add multiple scattered discontinuous projection, between each projection, (or use many wedges for concave surface
Band), race the most correspondingly makes male and fomale(M&F) and mates use with the projection promoting steel band and concave surface, although also can effectively realize carrying
Rise the guiding of steel band, but the critical defect of this structure is exactly to cause promoting the coefficient of friction of steel band and race relatively greatly, promotes steel
Band cannot skid, and according to elevator standard, no matter which kind of reason of elevator is trapped in hoistway, steel wire rope should be allowed to beat on rope sheave
Sliding, this kind of structure cannot realize skidding, and therefore, its application is extremely limited.Promote it addition, manufacture this kind of concaveconvex shape
The cost of steel band is higher compared with common platypelloid type steel band.
Such as the Chinese patent of Application No. 200780100831.4, although its two sides is also provided with circular arc spigot surface, but
Owing to its arc surface is to steel band inner recess so that thickness of strips is incremented by both sides by center position, its leading block is also
Being traditional drum type structure, owing to the inevitable defect of drum type structure is exactly that middle stress is bigger than normal, stress is inconsistent, and
Steel band is but minimum at its thickness of position that middle stress is maximum, therefore, easy cracking in the middle of steel band, once ftracture, then without
Method guides.
The and for example Chinese patent of Application No. 200810120635.X, it is (per share that its steel band two sides is provided with multiple arc surface
The corresponding arc surface of steel wire), this design has identical defect with the steel band of polywedge bet or band male and fomale(M&F), is i.e. to increase
Having added the contact area of steel band and pulley, thus caused coefficient of friction relatively big, promoting steel band cannot be realized by elevator standard requirement
Skid.Furthermore, promote steel band two sides and multiple arc surface is set, its multiple arc surfaces requiring to be also provided with correspondence on pulley, for
The requirement on machining accuracy of pulley is the highest, and the making required precision of the multiple circular arcs simultaneously promoting steel band is the highest, once promotes
The arc accuracy of steel band and pulley is inadequate, is made up of multistrand rope owing to promoting steel band and is connected, may result in lifting
There is multi-point constraint in steel band, causes the situation of Planar Mechanisms, is formed and pull between each circular arc, is easily caused lifting steel band abrasion and adds
Acute and produce cracking due to discontinuity.
