Preferably, be also provided with normally closed switch between emergency source of electrical power and induction coil, described normally closed switch also connects elevator control gear, and it is subject to the direct control of elevator control gear, controls the switching device of emergency source of electrical power.
Use the elevator of the speed reduction gearing of the claims, comprise lift car, and be arranged on the elevator slide rail of lift car both sides, on elevator slide rail or outside lift car, be also arranged at electromagnetic damping speed reduction gearing.
Preferably, electromagnetic damping speed reduction gearing comprises the induction coil be arranged on elevator slide rail or outside lift car; Induction coil is also connected with elevator control gear, emergency source of electrical power, speed detector in turn; The running velocity of speed detector induction elevator, and send this speed to elevator control gear; Elevator control gear is according to the mode of operation of the speeds control emergency source of electrical power sensed.
Also be provided with normally closed switch between emergency source of electrical power and induction coil, normally closed switch also connects elevator control gear, and it is subject to the direct control of elevator control gear, controls the switching device of emergency source of electrical power.
Compared with prior art, the beneficial effects of the utility model are: speed detector occurs abnormal by the acceleration/accel after breaking to steel rope during elevator motion and makes rapid reaction, (elevator lower guide serves as iron core to make electromagnet, guide rail wound upon themselves coil, in this, as electromagnet) itself there is electric current to pass through, and guide rail is all magnetized, and the magnetic flow that the car now moved downward penetrates when cutting magnetic induction line is in change, therefore, car receives electromagnetic damping, thus make steel rope disconnected after in elevator personal casualty be reduced.
The utility model accelerates the processing speed of elevator emergency disposal system to elevator speed exception, and avoid due to elevator stall or elevator cables break as far as possible, to the danger taking the personal safety that elevator personnel produce, improve the reliability operation degree of elevator.
