Description
Technical field
The present invention relates to the elevator field, a kind of pulley for flat pattern composite steel band guiding particularly, this pulley is mainly as the traction sheave on elevator, track adjusting wheel, crosshead sheave, sedan-chair return pulley, to roller etc.
Background technology
Elevator is as a kind of vertical transport instrument, closely bound up with modern society life, along with the quickening of socioeconomic development and urbanization process, make high-rise more and more, and high-rise has become the sign in a city, and some even becomes the terrestrial reference in city.Along with appearance and the socio-cultural development of high-rise, be more and more powerful for the demand of elevator, particularly entered today of social senilization, the meaning of elevator is more great.Every day born a large amount of stream of peoples and the transportation of logistics all in running by global elevator, and it is extremely important that the effect that elevator is born in building has become, and is the indispensable part of modern society's life.
Traditional elevator mainly uses steel rope as traction and the carrier hung, and steel rope is carrying the weight of car and counterweight not only as safety component, especially as the carrier of traction, drives lift car and turns round up and down.Steel rope has been used many year as the elevator vitals, but its shortcoming is also very obvious, and steel rope has that rolled steel dosage is large, easily wearing and tearing, discontinuity, need lubricate, can get rusty, maintain the shortcomings such as trouble, installation requirement height.Therefore, development along with elevator technology, the trend of steel rope has appearred replacing with composite steel band, and will be main flow future, the advantage of composite steel band is that steel rope is incomparable, and composite steel band also has its shortcoming certainly, such as the easy sideslip of composite steel band left and right migration, cause vibration of elevator to produce noise, also aggravated the wearing and tearing of composite steel band simultaneously.
For avoiding composite steel band departing from pulley, existing pulley such as Chinese patent 00805967.5 and 201020530296.5, national standard (standard No. is GB/T11358-1999) etc. all are partial to adopt drum type groove 8a(such as Fig. 1), Chinese patent 200480043744.6 adopts concave slot 8b(such as Fig. 2), this kind grooved has tangential force to produce, thereby guarantees that composite steel band moves to the center on wheel.But will cause like this internal stress with the middle part greater than both sides, and the general flakiness ratio of traditional flat rubber belting is larger, internal stress obtains cambic release at Width.but width and the Thickness Ratio of the band that uses on elevator are smaller, adopt such technical scheme, stressed more peripheral the wanting greatly of composite steel band centre portion, the be squeezed overplate at top of the overplate of composite steel band bottom is stretched, the steel band discontinuity, easily cause composite steel band overplate cracking and steel band is damaged, and when wheel turnover wheel face contact with composite steel band and can experience the cross section bending, when not contacting thereafter, external force does not disappear, band reverts to the plane, internal stress changes relatively sharply, there is the flexural fatigue phenomenon, number of run acquires a certain degree, the inner wire wire rope core occurs separating with integument, cause the middle part cracking, composite steel band is scrapped, operation life reduces.With regard to present production technology, the cost of composite steel band is still higher, is about 8～10 times of steel rope cost, therefore should take into full account the service life of composite steel band.
also there are some designs to adopt the concaveconvex shape composite steel band, for example Chinese patent 200810061529.9, change in shape at composite steel band exactly, increase male and fomale(M﹠F) (or adopting polywedge bet), also correspondingly make male and fomale(M﹠F) on race, although also can effectively realize the guiding of composite steel band, but the critical defect of this structure is exactly to cause the friction coefficient of composite steel band and race larger, composite steel band can't skid, according to elevator standard, no matter which kind of reason of elevator is trapped in hoistway, should allow steel rope to skid on rope sheave, this kind structure can't realize skidding, therefore, its application is very limited.In addition, manufacture the cost of this kind concaveconvex shape composite steel band higher compared with common platypelloid type steel band.
Summary of the invention
