Description
Technical field
The utility model relates to elevator field, a kind of lifting steel band that can realize enhanced feature particularly, and this lifting steel band is used mainly as elevator hoisting, carrying, suspension and lifting component.
Background technique
Traditional elevator is mainly used wire rope as the carrier of traction and hanging, and wire rope, not only as safety component, is carrying the weight of car and counterweight, especially as the carrier of traction, drives elevator cab to turn round up and down.Wire rope has been used many years as elevator vitals, but its shortcoming is also very obvious, and wire rope has large, the easy wearing and tearing of rolled steel dosage, discontinuity, needs lubricate, can get rusty, maintain the shortcomings such as trouble, installation requirement height.In prior art, normal V-type band otch and the U-shaped band otch of adopting increases traction capacity, but can cause wire rope internal stress excessive, thereby causes disconnected strand of steel rope abrasion, fracture of wire, even wire cable rupture.Therefore, along with the development of elevator technology, occurred by the trend that promotes steel band and replace wire rope, and future will be main flow, the advantage that promotes steel band is that wire rope is incomparable, certainly to promote steel band also have its shortcoming.First, because each wire rope in steel band is relatively independent, position, space can only lean on nonmetallic material to fill, and due to the long-term Tensile of nonmetallic material and flecition, easily causes ftractureing in the middle of steel band, once cracking, steel band is scrapped, and loss is serious.Promote in addition the easy sideslip of steel band left and right migration, cause vibration of elevator to produce noise, also aggravated to promote the wearing and tearing of steel band simultaneously.
For avoiding promoting steel band departing from pulley, existing pulley for example standard GB/T/T11358-1999 adopts drum type groove 8a (as Fig. 1), and this kind of grooved has tangential force to produce, thereby guarantee to promote steel band 22 ' Lun Shangxiang center, moves.But will cause that the internal stress with intermediate portion is greater than both sides like this, and the general flakiness ratio of traditional flat rubber belting is larger, internal stress obtains cambic release at width direction.But width and the Thickness Ratio of the band using on elevator are smaller, adopt such technological scheme, promote stressed the wanting greatly compared with periphery of steel band intermediate portion, the be squeezed coating at top of the coating that promotes steel band bottom is stretched, steel band discontinuity, easily cause lifting steel band coating cracking and steel band is damaged, and when wheel turnover wheel face with promote steel band and contact and can experience cross section bending, while not contacting thereafter, external force does not disappear, band reverts to plane, internal stress changes relatively sharply, there is flexural fatigue phenomenon, number of run acquires a certain degree, inner wire wire rope core occurs separated with coating, cause intermediate portion cracking, promoting steel band scraps, service life reduces.With regard to current production technology, the cost that promotes steel band is still higher, is about 8～10 times of wire rope cost, therefore should take into full account the working life that promotes steel band.
Also there are some designs to adopt concaveconvex shape to promote steel band, for example Chinese patent 200810061529.9, at lifting steel band, do in shape to change exactly, increased the discontinuous projection of a plurality of dispersions, between each projection, be concave surface (or adopting poly Vbelt), on race, also correspondingly make male and fomale(M&F) and mate use with the projection and the concave surface that promote steel band, although also can effectively realize the guiding that promotes steel band, but the critical defect of this structure is exactly that to cause promoting the friction factor of steel band and race larger, promoting steel band cannot skid, according to elevator standard, no matter which kind of reason of elevator is trapped in hoistway, should allow wire rope to skid on rope sheave, this kind of structure cannot realize skids, therefore, its application is very limited.In addition, manufacturing this kind of concaveconvex shape, to promote the cost of steel band higher compared with common tablet steel band.
As the application number Chinese patent that is 200780100831.4, although its two sides is also provided with circular arc guide surface, but because its arc surface is to steel band inner recess, thickness of strips is increased progressively to both sides by central direction, its leading block or traditional drum type structure, because the inevitable defect of drum type structure is exactly middle stressed bigger than normal, stressed inconsistent, and at its thickness of the position of the stressed maximum in centre, be but minimum at steel band, therefore, cracking in the middle of steel band, easily ftractures, once cannot lead.
The Chinese patent that and for example application number is 200810120635.X, its steel band two sides is provided with a plurality of arc surfaces (the corresponding arc surface of per share steel wire), this design and poly Vbelt or there is identical defect with the steel band of male and fomale(M&F), be the area of contact that has greatly increased steel band and pulley, thereby cause friction factor larger, promoting steel band cannot realize and skidding by elevator standard requirement.Moreover, promote steel band two sides a plurality of arc surface projections are set, it requires also to arrange on pulley a plurality of crown face grooves of correspondence, requirement on machining accuracy for pulley is very high, the making required precision of a plurality of circular arcs that simultaneously promotes steel band is also very high, once it is inadequate to promote the arc accuracy of steel band and pulley, owing to promoting steel band, by multistrand rope, formed and be connected, will cause promoting steel band and occur multi-point constraint (each arc surface projection of lifting steel band is subject to the constraint of crown face groove corresponding on pulley), caused the situation of constraint, between each circular arc projection, form and pull, easily cause promoting steel band wearing and tearing aggravation and because discontinuity produces cracking.
