The flat energy elevator is a safe and energy-saving elevator. The theory of the flat energy elevator is as follows:
1. possess independent multiple safety guarantee system:
safety is the most fundamental requirement of an elevator, and the existing elevator realizes safety, power, brake and other functions by means of a slender hoisting rope, so that the safety of the operation of the elevator is proved to be difficult to ensure completely. Therefore, even if a certain cost is added, it is necessary to establish an independent security system.
2. Be equipped with the elevator from stand-by power supply in area:
and a plurality of adverse effects caused by sudden power failure are avoided.
3. The traction steel cable is cancelled, the function of a counter-weight pull rope is realized by a light plate strip, and the functions of power transmission and braking force are realized by a main steel rail:
the change makes it possible to raise the speed of elevator greatly and avoid great safety accident, and makes the power transmission and braking effect even better.
4. Energy conservation principle:
how many things go up and how many things go down in the long term. The electric energy with small deduction is converted into mechanical energy loss, mechanical operation loss and wind resistance loss, and most of energy can be recycled, which is the theoretical basis for making an elevator capable of greatly saving energy. On the basis of the energy balance recovery system, the invention aims at saving energy greatly.
