Technical field
The present invention relates to the lifting system of a kind of elevator, more specifically, the present invention relates to the elevator traction system of a kind of big cornerite.
Background technology
In prior art, traction elevator mostly is single wheel design, and single guide deflection sheave list when the dark car counterweight of big load-carrying is rearmounted or when big load-carrying width car counterweight side is put, all can make rope spacing significantly increase so that traction wheel cornerite obviously reduces around structure. The wireline cornerite (the first cornerite) passed by traction wheel to be not less than 150 °, otherwise can skid, general traction system, this guide deflection sheave does not have power, also being exactly this 2nd cornerite not use, namely the effective cornerite of wireline in traction system be less than 150 °, particularly when designing ladder speed and require that increase or load-carrying increase, conventional single guide deflection sheave list can not meet the traction requirement of elevator around structure, and causes hoist ropes to skid.
Usually, the mode obtaining big traction in traction elevator has several as follows:
1, the positive pressure of wireline and traction wheel is improved, comprise and increase sedan-chair railway carriage or compartment light mass, reduction traction wheel grooved angle, increase undercut angles, in these methods, the safety coefficient of hoist ropes all can be made obviously to reduce owing to adding specific pressure, cost can be made significantly to increase, and traction increases not obvious;
2, improving cancellation ratio, increase compensated chain or tethered system, this can make product cost obviously increase, namely in order to obtain high cancellation ratio, the big load-carrying of a lot of high speed requires that lower traction still can not meet requirement, and owing to adding system weight, also reduces the safety coefficient of hoist ropes simultaneously;
3, traction wheel cornerite is increased, can too high main frame, adopt higher main engine bed, wireline after-combustion structure, but too high main frame cornerite increasing amount is very limited, generally will not adopt, and there is the work-ing life that twice inverse bending can significantly reduce hoist ropes due to hoist ropes in single guide deflection sheave after-combustion structure, in after-combustion structure in addition, traction wheel and guide deflection sheave groove number can be multiplied, and cause structure huge, and product cost can be caused to increase considerably.
