Background technology
Can GB GB7588-2003 requirement elevator maintain and protection company regularly (at least annually) detection band-type brake reliably brake, yet, because the method for existing detection band-type brake is more loaded down with trivial details, and be difficult for accomplishing even not having condition to accomplish, therefore, because of band-type brake, cannot reliably brake and occur that the terraced accident of even shearing passenger of pendant happens occasionally.
GB GB7588-2003 require elevator band carry 125% load when descending band-type brake can reliably brake.The method of testing of prior art is at car, to load the counterweight of 125% load-carrying.Such as the elevator of 1 ton of load-carrying needs to drag the counterweight of 1.25 tons of weights, go test, need the counterweight of 1.25 tons of weights to be transported to elevator on-site, then by manually counterweight being put into car.This method is not only loaded down with trivial details, if mixing up, cannot reliably not brake by band-type brake, if there is slipping ladder in moving up the process of counterweight, may there is elevator and shear carrying personnel's accident, because this testing is numerous and diverse, thereby generally when elevator annual test, can not detect elevator internal contracting brake braking, therefore, because of band-type brake, cannot reliably brake and occur that the terraced accident of even shearing passenger of pendant happens occasionally.
On the other hand, in order to guarantee load capacity and the security of operation of elevator, GB7588-2003 requires the coefficient of balance of elevator to reach 45%～50%, generally all by 50% requirement.This just requires the weight of counterweight suitable.Because the deadweight of car cannot be measured, know that whether added counterweight quantity is suitable, can only draw operation curve by the output current of frequency converter when loading counterweight load (20%, 45%, 50%, 80%, 100% several grade counterweights of general general load-carrying) test ascending for elevator from light to heavy and go downwards to intermediate floor in car, by the focus of curve, measure the coefficient of balance of elevator, if coefficient of balance does not meet the demands, add and subtract measuring by different counterweight loads again after pouring weight.This method both bothered, and was affected by human factors again very greatly, and the result recording is extremely inaccurate.
