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 mainly as
Elevator traction, carry, hang and promote assembly and use.
Background technology
Traditional elevator mainly uses steel wire rope to serve not only as safety component as traction and the carrier of hanging, steel wire rope, carrying
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 weight
Take parts and be 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.In prior art often
Use V-type band otch and U-shaped band otch to increase traction capacity, but steel wire rope internal stress can be caused excessive, thus cause
Steel rope abrasion, wire and strand breaking, even wire cable rupture.Therefore, along with the development of elevator technology, occurred in that with promoting
Steel band replaces the trend of steel wire rope, and would is that main flow future, and the advantage promoting steel band is that steel wire rope is incomparable, when
So promote steel band and also have its shortcoming.Firstly, since each bar steel wire rope is relatively independent in steel band, position, space can only be leaned on nonmetal
Material is filled, and due to the long-term Tensile of nonmetallic materials and flecition, is easily caused in the middle of steel band and ftractures, once open
Splitting, steel band is scrapped, and loss is serious.Additionally promote the easy sideslip of steel band left and right migration, cause vibration of elevator to produce noise, with
Time also exacerbate promote steel band abrasion.
For avoiding promoting steel band deviation on pulley, existing pulley such as standard GB/T/T11358-1999 uses drum type
Groove 8a (such as Fig. 1), this kind of grooved has tangential force to produce, thus ensures that promoting steel band 22 ' moves at Lun Shangxiang center.But
Being so the internal stress causing band middle part to be more than both sides, and the universal flakiness ratio of traditional flat rubber belting is bigger, inside should
Power obtains cambic release at width.But the width of the band used on elevator is smaller with thickness ratio, uses such
Technical scheme, promote steel band mid portion stress and want big compared with periphery, promotes the cover layer bottom steel band and is squeezed and top
Cover layer is then stretched, steel band discontinuity, easily causes lifting steel band cover layer cracking and makes steel band damage, and
During turnover wheel, wheel face contacts with lifting steel band and can experience section flexure, and when not contacting, external force disappears, and band reverts to plane,
The most drastically, there is flexural fatigue phenomenon in internal stress change, number of run reaches to a certain degree, inner wire wire rope core and bag
Separating occurs in covering layer, and causes middle part to be ftractureed, then promote steel band and scrap, and service life reduces.With regard to current production technology
Speech, the cost promoting steel band is the highest, and therefore about 8～10 times of steel wire rope cost should take into full account lifting steel band
Service life.
Also there are some to be designed with concaveconvex shape and promote steel band, such as Chinese patent 200810061529.9, it is simply that promoting steel
Make on belt shape to change, add multiple scattered discontinuous projection, be concave surface (or using polywedge bet) between each projection,
The most correspondingly make male and fomale(M&F) on race and mate use with the projection promoting steel band and concave surface, although also can effectively realize promoting steel
The guiding of band, but the critical defect of this structure is exactly that to cause promoting the coefficient of friction of steel band and race relatively big, promote steel band without
Method is skidded, and according to elevator standard, no matter which kind of reason of elevator is trapped in hoistway, steel wire rope should be allowed to skid on rope sheave,
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 due to
Its arc surface is to steel band inner recess so that thickness of strips is incremented by both sides by center position, and its leading block still passes
The drum type structure of system, owing to the inevitable defect of drum type structure is exactly that middle stress is bigger than normal, stress is inconsistent, and at 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, its steel band two sides is provided with multiple arc surface (per share steel wire
A corresponding arc surface), this design has identical defect with the steel band of polywedge bet or band male and fomale(M&F), is i.e. to considerably increase
Steel band and the contact area of pulley, thus cause coefficient of friction relatively big, promoting steel band cannot be realized skidding by elevator standard requirement.
Furthermore, promote steel band two sides and multiple arc surface projection is set, its multiple crown face grooves requiring to be also provided with correspondence on pulley,
Requirement on machining accuracy for pulley is the highest, and the making required precision of the multiple circular arcs simultaneously promoting steel band is the highest, once
The arc accuracy promoting steel band and pulley is inadequate, is made up of multistrand rope owing to promoting steel band and is connected, may result in
Promote steel band and occur that multi-point constraint (promotes the protruding pact by crown face groove corresponding on pulley of each arc surface of steel band
Bundle), cause the situation of Planar Mechanisms, formed between each circular arc projection and pull, be easily caused lifting steel band abrasion aggravate and due to
Discontinuity and produce cracking.
